'''{{PAGENAME}}''' lists and describes the major difficulties that may be faced by '''non-US persons''' who move to the US and so enter the US 'tax net', where they were previously outside it. Non-US persons are '''US nonresident aliens'''. That is, they are not '''US citizens''' and not '''US permanent residents''' (also known as green card holders).

The US has complicated<ref>{{cite web| publisher=Wikipedia| url=https://en.wikipedia.org/wiki/Income_tax_in_the_United_States#The_complexity_of_the_U.S._income_tax_laws| title=Income tax in the United States § The complexity of the U.S. income tax laws| accessdate=March 17, 2019}}</ref> tax laws that often apply unfavourably to non-US investment holdings and assets. These can create significant tax difficulties and expenses for new US residents who have investments or other assets in their non-US country and which they do not cash in before becoming US residents.

The information in this page describes the situation for ''new'' US residents, people who have ''moved to the US'' from other countries. It is also a list of considerations for anybody who is ''not yet'' a US resident but is contemplating becoming one in future.

==Introduction==
{{see also|Tax basics}}

In contrast to countries that allow an initial period of ''non-domicile'' residence before becoming a full taxable resident, the US taxes its residents on their worldwide income, and applies its full tax code, from the moment that an individual becomes a US tax resident. It has [[Passive foreign investment company|punitive tax laws]] for assets or investments held outside of the US by US residents.

This combination causes problems for new US residents who leave investments or assets behind in their previous country of residence when they move to the US. The sections below describe how new US residents can face unpleasant US tax surprises.

==US residency for tax purposes==

===Definition of US residency for tax purposes===

The US uses two separate tests to determine "residency for tax purposes".<ref group=note>Your US "residency for tax purposes" does not necessarily match your US residency for immigration purposes. For example, under the ''substantial presence test'' you can become a US taxable person but not be a US resident under US immigration law. Conversely, under the ''green card test'', if you have not yet entered the US you are technically a US permanent resident according to US immigration law, but not yet a US taxable person.</ref> These are:
* the ''[https://en.wikipedia.org/wiki/Green_Card_Test green card test]'', and
* the ''[https://en.wikipedia.org/wiki/Substantial_Presence_Test substantial presence test]''.

Under the ''[https://en.wikipedia.org/wiki/Green_Card_Test green card test]'', you are a US taxable person if you have spent at least one day in the US as a permanent resident. Note that under this test, it is ''not'' a requirement that you possess a physical ''[https://en.wikipedia.org/wiki/Green_card green card]'', just that your application is approved and activated. Also, note that you are not a US taxable person if you have received the card, but have yet to enter the US.

Under the ''[https://en.wikipedia.org/wiki/Substantial_Presence_Test substantial presence test]'', the US counts the number of days of presence in the country in a given year, including weighted periods of presence in prior years.<ref group=note>The actual calculation is: (days present in the tax year) + (1/3) &times; (days present in the year before the tax year) + (1/6) &times; (days present in the year two years before the tax year).</ref> If this exceeds 183, unless you can use the ''[https://www.irs.gov/individuals/international-taxpayers/closer-connection-exception-to-the-substantial-presence-test closer country exception]'', you are a US taxable person for that year.

For the year of arrival, it is generally possible to apply ''split year'' tax treatment, so that you do not suffer US tax on income that occurred before you moved to the US.<ref name="split year">{{cite web| url=https://www.irs.gov/individuals/international-taxpayers/taxation-of-dual-status-aliens| title=Taxation of Dual-Status Aliens| publisher=IRS| accessdate=October 8, 2020}}</ref> However, electing this has some potential disadvantages. You cannot use the US standard deduction, and you cannot file a joint return with a spouse.<ref name="pub501">{{cite web| url=https://www.irs.gov/forms-pubs/about-publication-501| title=About Publication 501, Dependents, Standard Deduction, and Filing Information| publisher=IRS| accessdate=October 9, 2020}}</ref> Both of these disadvantages may increase your US tax liability relative to a similarly situated US citizen.

After the year of arrival, assuming you remain in the US, under the ''substantial presence test'' you will be a full US taxable person for the years that follow. For those years, you will be able to use the normal deductions and filing statuses available to US citizens.<ref name="pub501" />

Once you are a US taxable person -- that is, you pass one of these two tests -- your ''entire worldwide income'' is instantly subject to full annual US taxation and reporting.

===J, F, M and Q visa holders===

If you moved to the US for employment, and do not have a green card, it is likely that you have either an H or an L visa.<ref>{{cite web| url=https://travel.state.gov/content/travel/en/us-visas/visa-information-resources/all-visa-categories.html| title=Directory of Visa Categories| publisher=US Department of State| accessdate=October 12, 2020}}</ref> For these visas, the ''substantial presence test'' applies. However, J, F, M and Q visa holders can exclude a few calendar years, so effectively delaying (or entirely avoiding) becoming US taxable persons.<ref>{{cite web| url=https://www.irs.gov/individuals/international-taxpayers/substantial-presence-test| title=Substantial Presence Test| publisher=IRS| accessdate=October 8, 2020}}</ref><ref>{{cite web| url=https://www.irs.gov/individuals/taxation-of-alien-individuals-by-immigration-status-j-1| title=Taxation of Alien Individuals by Immigration Status – J-1| publisher=IRS| accessdate=October 8, 2020}}</ref>

If you later transition to an H or L visa, or a green card, you lose the benefits of staying outside the US tax system yet living in the US under a J or similar visa.

===Timing becoming a US taxable person===

If you meet the ''substantial presence test'' for a year, your residency start date is generally the first day of presence in the US during that year. If you meet the ''green card test'', your residency start date is the first day of presence in the US as a permanent resident. The IRS provides a [https://www.irs.gov/individuals/international-taxpayers/alien-residency-examples number of examples] of when your US tax residency begins.

If you have deferred income in a given year, it may be worthwhile to try and delay becoming a US taxable person, or if possible, making use of any window of time during which you can be physically present in the US but not yet a US tax resident. See [[#Earnings and salary|Earnings and salary]] below for more.
 
Pay particular attention to any pre-arrival trips you might make to the US. These have the potential to produce a surprising and unpleasant US tax outcome, by effectively backdating your arrival date to the date of the visit.<ref group=note>For example, suppose you move to the US on an H or L visa in mid-June, but spent three weeks on a training course in the US in January. Ordinarily, your arrival date would have been mid-June and failing the ''substantial presence test''. However, your January training course puts you over the ''substantial presence test'', and worse, the date you become a US taxable person is then January. So any earnings you made in March to June, and any actions you took to mitigate US tax before actually moving to the US, are now all US taxable items, potentially with disastrous results.</ref>

==US tax treaties==

If there is an ''income tax treaty''<ref name="treaties">{{cite web| url=https://www.irs.gov/businesses/international-businesses/united-states-income-tax-treaties-a-to-z| title=United States Income Tax Treaties - A to Z| publisher=IRS| accessdate=October 8, 2020}}</ref> between the US and the country where you retained non-US holdings, it ''may'' offer some limited protection against US tax problems on your non-US investments and assets.<ref group=note>At the time of writing, the US maintains income tax treaties with Australia, Austria, Bangladesh, Barbados, Belgium, Bulgaria, Canada, China, Cyprus, Czech Republic, Denmark, Egypt, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Indonesia, Ireland, Israel, Italy, Jamaica, Japan, Kazakhstan, Latvia, Lithuania, Luxembourg, Malta, Mexico, Morocco, Netherlands, New Zealand, Norway, Pakistan, Philippines, Poland, Portugal, Romania, Russia, Slovak Republic, Slovenia, South Africa, South Korea, Spain, Sri Lanka, Sweden, Switzerland, Thailand, Trinidad & Tobago, Tunisia, Turkey, Ukraine, United Kingdom, and Venezuela.</ref>

And if there is a separate ''estate tax treaty''<ref name="estate tax treaties">{{cite web| url=https://www.irs.gov/businesses/small-businesses-self-employed/estate-gift-tax-treaties-international| title=Estate & Gift Tax Treaties (International)| publisher=IRS| accessdate=October 10, 2020}}</ref> between the US and the country where you retained non-US holdings, it ''may'' offer some protection against confiscatory US estate tax on your assets, should you die while a US resident.<ref group=note>At the time of writing, the US maintains estate tax treaties with Australia, Austria, Canada, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Japan, Netherlands, South Africa, Switzerland, and the United Kingdom. The estate tax treaties with Ireland and South Africa may be deficient in important areas.</ref>

Canada does not have a separate estate tax treaty with the US. Instead, the US maintains a single treaty with Canada that combines both income taxes and estate taxes. Under this combined treaty, Canadians receive protection up to the level of the US estate tax exemption allowed to US citizens, the same as generally provided by the separate US estate tax treaties for other countries.<ref>{{cite web| url=https://www.irs.gov/businesses/international-businesses/canada-tax-treaty-documents| title=Canada - Tax Treaty Documents| publisher=IRS| accessdate=August 9, 2020}}</ref>

It will be worth being familiar with any applicable treaty. However, reading treaties is not a simple exercise. Most are written in dense prose, and some exist only as an elderly basic treaty but with many clauses overridden by subsequent ''protocols''. And US income tax treaties usually contain a ''saving clause''<ref>{{cite web| url=https://www.irs.gov/businesses/tax-treaties-can-affect-your-income-tax| title=Tax Treaties Can Affect Your Income Tax| publisher=IRS| accessdate=October 12, 2020}}</ref> that, for US residents (and US citizens), denies most treaty benefits that would mitigate US tax. For example:

{{quotation|Notwithstanding any provision of this Convention except paragraph 5 of this Article, a Contracting State may tax its residents (as determined under Article 4 (Residence)), and by reason of citizenship may tax its citizens, as if this Convention had not come into effect.|US/UK tax treaty, Article 1 paragraph 4<ref>{{cite web| url=https://www.treasury.gov/resource-center/tax-policy/treaties/Documents/uktreaty.pdf| title=U.S.-U.K. income tax treaty, signed July 24, 2001, London| publisher=US Treasury| accessdate=October 12, 2020}}</ref>}}

==Delayed or deferred earnings and salary==

Income is often paid to employees in arrears, so it is quite possible that you will receive your final non-US paycheck when a US taxable person. This can generate an unwanted and perhaps unnecessary US tax liability, because the US taxes income based on date of receipt.<ref>{{cite web| url=https://www.irs.gov/businesses/small-businesses-self-employed/what-is-taxable-and-nontaxable-income| title=What is Taxable and Nontaxable Income?| publisher=IRS| accessdate=October 8, 2020}}</ref>

If you have coverage from a US income tax treaty,<ref name="treaties" /> this may (if not overridden by a treaty ''saving clause'') offset that issue, because treaties usually reserve taxing rights on employment income to the country in which the work was performed. Otherwise, or to avoid this issue, it is usually best to accelerate income where possible so that you receive it before becoming a US taxable person. Receiving it afterwards may lead to double-tax.

==Tax and reporting for non-US cash accounts==

The US requires you to report any non-US financial accounts above a relatively low threshold amount on 'informational' forms. These reports have to be made annually, and while broadly duplicative,<ref name="duplicative">{{cite web| url=https://www.irs.gov/businesses/comparison-of-form-8938-and-fbar-requirements| title=Comparison of Form 8938 and FBAR Requirements| publisher=IRS| accessdate=November 4, 2019}}</ref> one or both of the following may required:

* [https://www.irs.gov/forms-pubs/about-form-8938 Form 8938], Statement of Foreign Assets. Here you list the details, income and balances of all your non-US accounts.
* [https://www.irs.gov/businesses/small-businesses-self-employed/report-of-foreign-bank-and-financial-accounts-fbar FinCEN Form 114], Foreign Bank Account Reporting (FBAR). Filed annually with the Financial Crimes Enforcement Center. This form can only be filed electronically. The threshold for filing is very low, just $10,000 in non-US accounts.

It is easy to overlook these forms, but the penalties for non-filing are huge, starting at $10,000 even for ''non-wilful'' errors.<ref group=note>In 2015, congress mandated the IRS to revise the FBAR penalty amounts upwards from $10,000 and $100,000, citing "inflation" as the reason for the increases. Notably however, the threshold non-US account balance for filing this form has remained at $10,000 since the FBAR was first introduced in 1970. Unlike the penalties for non-filing, the threshold has ''never'' been increased for inflation. For more, see: {{cite web| url=https://sherayzenlaw.com/us-taxpayers-nightmare-continues-fbar-penalty-inflation-adjustment/| title=US Taxpayers’ Nightmare Continues: FBAR Penalty Inflation Adjustment| publisher=Sherayzen Law| accessdate=November 3, 2019}}</ref>

Since the ''[https://en.wikipedia.org/wiki/Foreign_Account_Tax_Compliance_Act Foreign Account Tax Compliance Act]'' (FATCA) passed into law in 2010, a number of non-US financial institutions now regularly refuse accounts to US citizens and US residents, and some may unilaterally close the accounts of anyone who becomes a US citizen or US resident. You will want to be certain that any non-US bank or other financial institution you hold accounts with will allow you to maintain those accounts after you have become a US taxable person. Under FATCA, non-US banks must provide the IRS with details of the assets of, and interest and dividend payments made to, US residents and US citizens.<ref group=note>The actual mechanism here is generally that non-US banks report information to their ''local'' tax authorities, and these authorities then forward that information to the IRS under cover of FATCA ''intergovernmental agreements'' (IGA).</ref>

===Non-US savings accounts and other interest-paying accounts===

As well as reporting the existence of any non-US savings or interest bearing accounts annually on Form 8938 and FinCEN Form 114, you also need to report any interest income you receive from these accounts as US taxable income. US banks will send Form 1099 to investors to inform them of the taxable interest they have receive, but you will probably not receive these forms from non-US banks.

Without a Form 1099, you have to account for the interest yourself on your US tax return, computing the USD equivalent to whatever you received, and using the exchange rate in effect on the date of payment. If your foreign bank pays you interest monthly, this can quickly become a huge workload. Also, note that non-US savings accounts that are tax-sheltered or tax-free in the country where the account is based are generally not sheltered from US tax. For example, a UK cash [[UK Individual Savings Accounts|Individual Savings Account]] (ISA) is fully taxable to the US for a US resident.

In many cases, the best way to handle this problem is to simply cash in these accounts before becoming a US resident, convert the balance to USD and transfer it into your US accounts, and then re-invest the money in US savings accounts once you are a US resident.

==Non-US investment accounts==

As with [[#Non-US cash accounts|non-US cash accounts]] above, these accounts need to be reported on [https://www.irs.gov/forms-pubs/about-form-8938 Form 8938] and [https://www.irs.gov/businesses/small-businesses-self-employed/report-of-foreign-bank-and-financial-accounts-fbar FinCEN Form 114] if you meet the asset limits for reporting. Note that these 'informational' reports generally encompass non-US pensions as well as any and all other non-US investment accounts. Also similarly to non-US cash accounts, any investment accounts you hold in non-US financial institutions are at risk of closure, if these financial institutions have a policy of avoiding US FATCA reporting.

===PFIC tax penalty for non-US taxable accounts===

Directly holding shares or bonds poses no particular problems, but any ETFs, funds, investment trusts or other collective investment vehicles held before becoming a US taxable person are ''very likely'' to be non-US domiciled, making them [[Passive foreign investment company|passive foreign investment companies]] (PFICs).<ref>{{cite web| url=https://hodgen.com/what-is-a-pfic/| title=What is a PFIC?| publisher=HodgenLaw PC| accessdate=October 15, 2020}}</ref>

The US tax rules on PFICs are harsh to the extent that they entirely discourage ownership.<ref>{{cite web|url= https://thunfinancial.com/why-americans-should-never-ever-own-shares-in-a-non-us-incorporated-mutual-fund/|title=Why Americans Should Never Own Shares in a Non-US Mutual Fund (PFIC)|last=Kuenzi | first=David| date=2016 |website=https://thunfinancial.com | publisher= Thun Financial Advisors | accessdate=December 30, 2016}}</ref> But because US tax laws for US domiciled ETFs held by nonresident aliens are also [[Nonresident alien taxation|harsh]], most nonresident aliens will [[Nonresident alien investors and Ireland domiciled ETFs|prefer non-US domiciled funds and ETFs]]. This makes it probable that any existing investments you hold on moving to the US are PFICs. If you hold any non-US domiciled funds or ETFs, your main defence against PFIC issues is to sell these before you become a US taxable person.

Beyond this, in all cases you should also consider selling (and then potentially repurchasing) any assets you own that have a built-in and as yet unrealised capital gain. The US taxes capital gains based on the difference between the USD value at purchase and the USD value at sale,<ref>{{cite web| url=https://www.irs.gov/taxtopics/tc409| title=Topic No. 409 Capital Gains and Losses| publisher=IRS| accessdate=October 9, 2020}}</ref> and provides no step-up in basis for when you move to the US.<ref name="carltonfields">{{cite web| url=https://www.carltonfields.com/files/Uploads/Documents/all/us-pre-immigration-tax-planning-brochure-english.pdf| title=US Pre-Immigration Tax Planning| publisher=Carlton Fields| accessdate=October 9, 2020}}</ref> Without washing away any capital gains before moving to the US, you could find yourself having to pay a large and unnecessary US capital gains tax on gains that occurred years or even decades before you set foot in the US.

Long-term bond and CD-like saving holdings taken out before becoming a US resident may pay out their interest after you become a US taxable person. In this case, investigate if it is possible to allocate any part of the interest payment to periods before becoming a US resident.

===Non-US tax-advantaged accounts lose tax advantage===

Unless any applicable US tax treaty<ref name="treaties" /> specifically mentions them,<ref group=note>This happens rarely, if ever.</ref> any non-US accounts that are not pensions, but are tax-advantaged or tax-free to residents of the country in which they are based, lose their special status and become taxable to the US when you are a US resident. Examples include UK [[UK Individual Savings Accounts|Individual Savings Accounts]] (ISA), Canadian [[finiki:Tax-Free Savings Account|Tax-Free Savings Accounts]] (TFSA), and French [[Wikipedia:fr:Assurance-vie en France|Assurance-vie]] and [[Wikipedia:fr:Plan d'Épargne en Actions|Plan d'Épargne en Actions]] accounts.

For all such accounts, consider closing or collapsing them before becoming a US taxable person. If this is not possible, or not desirable, at the minimum you should ensure that they contain no PFICs. The most likely, but cleanest, US tax outcome is that the US will treat these as ordinary unwrapped taxable investment accounts. Less clean is if the US treats them as foreign trusts.

In all cases, as with [[#Taxable accounts|taxable accounts]] above, you will want to wash out any capital gains in these accounts ''before'' becoming a US taxable person. The advantage with these accounts is that you will generally incur no non-US capital gains taxes by doing this while still a resident in the country where the accounts are located. Conversely, if any assets in the accounts have built-in capital losses, it may be worth deferring selling these until ''after'' you are a US resident, so that you can then use these losses to offset any future US capital gains taxes.

===Non-US pensions may lose pension status===

A few US tax treaties<ref name="treaties" /> cover non-US and cross-border pensions well,<ref group=note>The US tax treaties with the UK and Canada are known 'good' treaties in this respect.</ref> but where one does not, this can leave you with a problematic and unpleasant situation where you hold a non-US pension.<ref>{{cite web| url=https://www.irsmedic.com/blog/2015/03/foreign-retirement-plan-taxable.html| title=Is your foreign retirement or pension plan taxable? Is it reportable?| publisher=IRS Medic| accessdate=October 15, 2020}}</ref> Note that whether or not they are exempt by treaty from annual US taxation, pensions are ''not exempt'' from [https://www.irs.gov/forms-pubs/about-form-8938 Form 8938] and [https://www.irs.gov/businesses/small-businesses-self-employed/report-of-foreign-bank-and-financial-accounts-fbar FinCEN Form 114] reporting.

If the pension is not covered by treaty but can be collapsed or otherwise unwound, it can be worth doing this before becoming a US taxable person. Otherwise, a number of US tax treatments are possible,<ref>{{cite web| url=https://www.bdo.com/insights/tax/private-client-services/foreign-trusts-from-a-united-states-perspective-ta| title=Foreign Trusts From a United States Perspective: Taxpayer Nightmares and How to Keep Them from Happening| publisher=BDO| accessdate=October 9, 2020}}</ref> but most if not all can often lead to double-tax on pensions; once annually to the US while assets grow, then again to the country where the pension is located on withdrawals.

For cases not covered by treaty, and where collapsing or unwinding the pension is not possible or not desirable, there may be few defences against this unpleasant and costly US tax treatment. Damage limitation may be your only option. As with other account types above, making sure that the accounts contain no PFICs and washing away any built-in gains before becoming a US taxable person are usually sensible moves. You might also consider holding only your lower growth assets in these pensions, to try to further reduce any double-tax outcomes.

Depending on the nature of your non-US pension, you may find yourself having to complete one or more of the following forms:
* [https://www.irs.gov/forms-pubs/about-form-8833 Form 8833], Treaty-Based Return Position Disclosure. Used to claim tax treaty benefits.
* [https://www.irs.gov/forms-pubs/about-form-8621 Form 8621], Information Return by a Shareholder of a Passive Foreign Investment Company (PFIC). Extremely time-consuming, but required if you hold any non-US domiciled funds or ETFs. The IRS's estimated time to complete this form is over 48 hours.<ref>{{cite web| url=https://www.irs.gov/instructions/i8621| title=Instructions for Form 8621| publisher=IRS| accessdate=November 3, 2019}}</ref>
* [https://www.irs.gov/forms-pubs/about-form-3520 Form 3520], Annual Return to Report Transactions With Foreign Trusts and Receipt of Certain Foreign Gifts. For any activity involving non-US trusts, and also for gifts and bequests from non-US sources above $100,000.
* [https://www.irs.gov/forms-pubs/about-form-3520-A Form 3520-A], Annual Information Return of Foreign Trust with a US Owner. Required if you own a non-US trust. Another extremely time-consuming and complex form.

==Non-US real estate==

{{anchor|visa uncertainties}}Non-US real estate can produce several of the most vexing problems for new US residents. Moving to the US on a work visa, for example H or L, is an uncertain prospect. Your US residency status is entirely dependent on your employment, and if you lose or leave your job, you have just 60 days in which to either find another job with an employer willing to sponsor an H visa,<ref group=note>If the annual H-1B visa cap has already been reached, this may not be possible. For more, see: {{cite web| url=https://en.wikipedia.org/wiki/H-1B_visa#Congressional_yearly_numerical_cap_and_exemptions| title=H-1B visa § Congressional yearly numerical cap and exemptions| publisher=Wikipedia}}</ref> or leave the US to avoid becoming 'out of status' for US immigration.<ref>{{cite web| url=https://www.alllaw.com/articles/nolo/us-immigration/what-happens-h-1b-holder-loses-job.html| title=What Happens If an H-1B Holder Loses Their Job?| publisher=NOLO| accessdate=October 10, 2020}}</ref>

===Retaining your non-US principal residence===

Because of the visa uncertainties [[#visa uncertainties|outlined above]], it is common for people moving from other countries to the US to retain ownership of their previous home, perhaps renting it out, until they are certain that their residency in the US is secure. This period can extend for several years, perhaps while waiting for permanent residency (green card) processing. However, these actions do not intersect well with US tax laws.
 
====Tax on rental income====

If you keep your home in your previous country, and rent it out while a US resident, your rental income is fully taxable to the US.<ref group=note>This usually results in a negative cash-flow. Suppose you rent your non-US home out for $2,000/month, and at the same time rent a home in the US for the same $2,000/month. You might think this would be neutral, but because of tax, it is not. The $2,000 you receive in rent is taxable income, but the $2,000 you pay in rent is not tax-deductible. As a result, you will lose out, to the extent of your marginal tax rate, so perhaps $500/month or more in deadweight tax cost.</ref> You will be able to claim some rental expenses,<ref>{{cite web| url=https://www.irs.gov/taxtopics/tc414| title=Topic No. 414 Rental Income and Expenses| publisher=IRS| accessdate=October 10, 2020}}</ref> but these are limited.

You can also claim depreciation on your non-US home rental, but the depreciation benefit is lower for non-US properties than it is for US ones.<ref>{{cite web| url=https://silvertaxgroup.com/foreign-rental-property-depreciation/| title=Understanding Foreign Rental Property Depreciation and IRS Income Guidelines| publisher=Silver Tax Group| accessdate=October 10, 2020}}</ref>

====Capital gains tax on sale====

In many countries, selling your principal home is entirely free of capital gains tax. However, the US limits tax-free gains. You can exclude up to $250,000 per individual if you have lived in this home for two of the past five years, otherwise there is no capital gains exclusion, and the entire gain on the property is US taxable.<ref>{{cite web| url=https://www.irs.gov/taxtopics/tc701| title=Topic No. 701 Sale of Your Home| publisher=IRS| accessdate=October 10, 2020}}</ref> This rule applies to all property sales, without regard for your having owned the home for years or decades before becoming a US resident or US taxable person.

Moreover, the gain is measured from purchase price ''in USD'' to sale price ''in USD'', with no step-up on becoming a US resident.<ref name="carltonfields" /> This can mean that, as with stocks and other investments mentioned above, you may end up with a US capital gains tax liability for gains that occurred years or even decades before you set foot in the US.

Some countries may offer a way to enter into a transaction that results in you 'resetting' your basis in a property for US tax purposes, without the property changing actual ownership. If it does, it will be well worthwhile considering doing this before becoming a US resident.

Otherwise, the only way to mitigate this is to either be sure to sell the property before exceeding the 'two of the past five years' rule, or to continue to own it until you have left the US and escaped from its 'tax net'.

====Tax on 'phantom' gains due to currency effects on sale====

Because the gain is measured as the difference between the house price ''in USD at the rate in effect at the time of purchase'' and the house sale proceeds ''in USD at the rate in effect at the time of sale'', there may be a gain (or loss) due purely to foreign exchange rate differences.

It is entirely possible to recognise a non-USD ''loss'' on selling a property that becomes a phantom USD ''gain'' solely because of exchange rate changes over the period of ownership. Unfortunately, you will have to pay the US tax on the ''phantom'' property gain with ''real'' money.

====Tax on 'phantom' gains when repaying a foreign mortgage====

If you pay off -- or even make normal repayments on -- a non-US mortgage, whether or not these repayments are related to selling a non-US property, there may be a further tax to pay due to foreign exchange rate changes. The US views repayments on a non-US mortgage as a potential currency gain, making it a taxable event.<ref>{{cite web| url=https://www.ustaxfs.com/foreign-mortgage-repayment-exchange-rate-gain/| title=Foreign Mortgage Repayment and Exchange Rate Gain| publisher=US Tax & Financial Services| accessdate=October 10, 2020}}</ref> This is a second way in which the US can tax a ''phantom'' property gain.

====Depreciation recapture tax====

If you rented out your house and took US tax deductions against rental income for depreciation, then on selling it the gain attributable to the depreciation is taxable at US income tax rates, rather than at capital gains tax rates.<ref>{{cite web| url=https://en.wikipedia.org/wiki/Depreciation_recapture_(United_States)| title=Depreciation recapture (United States)| publisher=Wikipedia| accessdate=October 12, 2020}}</ref> This tax rule yet again has the effect of further increasing your US tax liability on selling a property.

===Retaining your non-US investment real estate===

If you own investment real estate that is not your principal residence, then all of the tax rules for principal residence above apply. That is, [[#Tax on rental income|tax on rental income]], [[#Capital gains tax on sale|capital gains tax on sale]], [[#Tax on 'phantom' gains due to currency effects on sale|tax due to currency effects]], [[#Tax on 'phantom' gains when repaying a foreign mortgage|tax due to foreign mortgage repayments]], and [[#Depreciation recapture tax|depreciation recapture tax]].

The only difference is that you no longer have a two-year selling window for a $250,000 'principal residence' exemption for US capital gains tax, but may instead be liable for US capital gains tax on the entire gain in the property since buying it, even if you sell the very next day after becoming a US resident.

To avoid this harsh tax result, you should ''strongly consider'' selling -- or otherwise 'resetting' the US basis in -- any investment real estate that you own, and that has a built-in capital gain, ''before'' becoming a US resident. Conversely, if it happens to have a built-in capital loss, consider deferring the sale until ''after'' becoming a US resident; this will allow you to use the loss to offset future US capital gains taxes.

==US estate tax==
{{main article|Estate and inheritance tax}}

The US has a large estate tax exemption for citizens and [[Domicile|domiciled]] or permanent residents, but for individuals who are not [[Domicile|domiciled]] in the US, the estate tax exemption is just $60,000.<ref>{{cite web| url=https://www.irs.gov/individuals/international-taxpayers/some-nonresidents-with-us-assets-must-file-estate-tax-returns| title=Some Nonresidents with U.S. Assets Must File Estate Tax Returns| publisher=IRS| accessdate=October 10, 2020}}</ref> There is no unlimited marital exemption, unless your spouse is a US citizen. US estate tax rates for individuals not domiciled in the US are 26-40% of US assets above the $60,000 exemption.

As a new or temporary US resident, it is quite possible that you are subject to US income tax, but your domicile does not allow you to use the large US estate tax exemption for people domiciled in the US.<ref>{{cite web| url=https://en.wikipedia.org/wiki/Estate_tax_in_the_United_States#Non-residents| title=Estate tax in the United States| publisher=Wikipedia| accessdate=October 10, 2020}}</ref> This produces a difficult dilemma. You would only be subject to US estate tax on your 'US situs'<ref group=note name="US situs">'US situs' assets would include not just everything you own physically in the US and in US based account, but also US company stocks and any US domiciled funds or ETFs held in any non-US accounts that you possess</ref> assets (not your worldwide assets), but you cannot hold non-US domiciled funds or ETFs without falling foul of draconian US [[Passive foreign investment company|PFIC]] tax rules, and US domiciled funds and ETFs are 'US situs' assets. In this case, you risk significant US estate tax liabilities if you hold more than $60,000 in any US based investments or assets.

Nationals of one of the handful of countries with a US estate tax treaty<ref name="estate tax treaties" /> may be able to mitigate the US estate tax. Otherwise, the only way to mitigate this is to either become fully domiciled in the US, or keep 'US situs' assets to below $60,000 in total.

==US state income taxes==
{{main article|State income taxes}}

State income tax is too complex and disparate to fully cover here, but as a general rule, if you live in a state with an income tax, everything listed above that is federally taxable will have a state tax that is payable on top.

In addition, several states do not honour US income tax treaties.<ref group=note>For example, California famously does not recognise [[finiki:Registered Retirement Savings Plan|Canadian retirement accounts]] as tax-deferred. For more, see:{{cite web| url=http://gedeonlawcpa.com/how-does-california-ftb-tax-rrsp/| title=How Does California FTB Tax RRSP?| publisher=Gedeon Law and CPA| accessdate=October 10, 2020}}</ref> This can mean that gains in a non-US pension that are not taxable federally may nevertheless still be taxable annually to your state of residence. And it can create ridiculously complex scenarios, and also often leads directly to double-tax -- once when the gains accrue, and then again when you make withdrawals. This is a particular issue if you move state or country for retirement.

==Becoming a green card holder or US citizen==

One common way to alleviate [[#visa uncertainties|visa uncertainties]] caused by your US visa being tied to your job is to apply for US permanent residency (a ''[https://en.wikipedia.org/wiki/Green_card green card]''). Note however that while this will make your position as a US resident more secure, it comes with a series of drawbacks that may prove unpalatable, particularly for high net worth individuals.

Once approved for US [https://en.wikipedia.org/wiki/Green_card Lawful Permanent Resident] (LPR, ''green card'') status, your entire worldwide income is fully taxable to the US, no matter where in the world you live.<ref name="cbt">{{cite web| url=https://www.irs.gov/individuals/international-taxpayers/taxpayers-living-abroad| title=Taxpayers Living Abroad| publisher=IRS| accessdate=November 2, 2019}}</ref> Unlike all other developed nations, the US taxes not only on residency, but also on citizenship, and US LPRs are 'deemed' to be fully US taxable under citizenship-based taxation, even though not actually US citizens.

To free yourself from US tax as an LPR, you must generally affirmatively surrender your green card using USCIS [https://www.uscis.gov/i-407 Form I-407]. If you do not do this, you remain a US taxable person even if your physical green card (and very probably also your US immigration status) has expired.<ref>{{cite web| url=https://www.angloinfo.com/blogs/global/us-tax/tax-court-affirms-informal-relinquishment-of-green-card-not-enough/| title=Tax Court Confirms It — “Informal” Relinquishment of Green Card NOT Enough!| publisher=Angloinfo| accessdate=September 19, 2020}}</ref>

If you become a US citizen, and wish to free yourself from US tax, your only option is to renounce US citizenship.<ref>{{cite web| url=https://travel.state.gov/content/travel/en/legal/travel-legal-considerations/us-citizenship/Renunciation-US-Nationality-Abroad.html| title=Renunciation of U.S. Nationality Abroad| publisher=U.S. Department of State| accessdate=October 10, 2020}}</ref>

{{anchor|Expatriation tax}}In both cases, this may subject you to the US ''[[US tax pitfalls for a US person living abroad#Expatriation tax|expatriation tax]]''. This is an unpleasant tax that includes US capital gains tax on a 'deemed' disposition of assets with built-in gains, full and immediate US income tax on 'deemed' withdrawal of the value of any pensions and retirement savings (even when not actually withdrawn, and perhaps not even ''withdrawable'', if non-US), and a harsh 40% transfer tax on any subsequent gifts or bequests to US persons.<ref>{{cite web| url=https://www.withersworldwide.com/en-gb/insight/expatriation-and-compliance-what-you-need-to-know-now| title=Expatriation and compliance: What you need to know now| publisher=Withers Worldwide| accessdate=October 12, 2020}}</ref>

Given the above, it is worth thinking ''very carefully indeed'' about whether or not taking out a US green card or US citizenship is a sensible move. If you are a temporary US resident, or if you do not plan to spend the rest of your life in the US, it may be better to stick to employment-based visas exclusively. Many US immigration professionals now recommend this, in preference to obtaining a green card.<ref>{{cite web| url=https://hodgen.com/leaving-the-usa-and-leaving-u-s-tax-law-behind-you/| title=Leaving the USA and leaving U.S. tax law behind you| publisher=HodgenLaw PC| accessdate=October 12, 2020}}</ref>

==Temporarily leaving the US==
If you hold a green card, and intend to spend a period of several months outside the US, you may need to apply for a ''reentry permit''. From USCIS:

{{quotation|A lawful permanent resident (LPR) normally may travel outside the United States and return; however, there are some limitations. A reentry permit can help prevent two types of problems:
* Your Permanent Resident Card becomes technically invalid for reentry into the United States if you are absent from the United States for 1 year or more.
* Your U.S. permanent residence may be considered as abandoned for absences shorter than 1 year if you take up residence in another country.
A reentry permit establishes that you did not intend to abandon status, and it allows you to apply for admission to the United States after traveling abroad for up to 2 years without having to obtain a returning resident visa. Reentry permits are normally valid for 2 years from the date of issuance.|USCIS Guide B5, How do I get a reentry permit?<ref>{{cite web| url=https://www.uscis.gov/sites/default/files/document/guides/B5en.pdf| title=How do I get a reentry permit?| publisher=USCIS| accessdate=January 21, 2021}}</ref>}}
As noted [[#Becoming a green card holder or US citizen|above]], your entire worldwide earnings and assets remain both taxable and reportable to the US. It may be possible to claim tax treaty benefits to reduce any US tax, but doing so runs the risk of involuntary ''[[#Expatriation tax|expatriation]]''.<ref>{{cite web| url=https://hodgen.com/green-card-treaty-election-exit-tax-danger/| title=Green card + treaty election = exit tax danger| publisher=HodgenLaw PC| accessdate=January 21, 2021}}</ref>

Reentry permits are intended for temporary absence from the US, although there is no definition of ''temporary'' in the law or regulations surrounding them. They cannot be extended. You can apply for more than one, and must be physically present in the US to apply. There is no regulation that limits how many you can have, but issuance of each is at the discretion of the USCIS processing officer. Processing officers are required to assess the circumstances of an application, including any history of past applications.<ref>{{cite web| url=https://www.uscis.gov/policy-manual/volume-11-part-c| title=Policy Manual: Part C - Reentry Permits| publisher=USCIS| accessdate=January 21, 2021}}</ref>

{{anchor|Leaving the US}}
==Permanently leaving the US==

===Departing alien clearance===
Non-US citizens who leave the US are ''technically'' required to obtain a ''departure permit'' (also called a ''sailing permit').<ref name="1040c">{{cite web| url=https://www.irs.gov/individuals/international-taxpayers/departing-alien-clearance-sailing-permit| title=Departing Alien Clearance (Sailing Permit)| publisher=IRS| accessdate=January 21, 2021}}</ref>'<ref group=note>The use of the term ''sailing permit'' provides a clue to the outdated nature of this requirement.</ref>

Obtaining this certificate requires filing the following form:
* [https://www.irs.gov/forms-pubs/about-form-1040-c Form 1040-C], U.S. Departing Alien Income Tax Return. Reports income received or expected to be received for the entire tax year, with payment if required.

This form cannot be filed by mail or online, but only in person at selected IRS offices. Filing it requires you to supply copious documents supporting all of your received and expected income for the year.<ref name="1040c" /> Again ''technically'', this form applies not only to green card holders, but also to holders of a work visa such as H or L. Also, ''technically'' it apparently applies to ''any'' departure from the US, even temporary ones, for example a short vacation.

This is all ''technically''. In practice, neither the IRS nor USCIS has enforced this requirement in decades, and compliance is virtually nonexistent.<ref>{{cite web| url=https://www.gao.gov/assets/310/303328.pdf| title=GAO-10-429 Tax Compliance: IRS May Be Able to Improve Compliance for Nonresident Aliens and Updating Requirements Could Reduce Their Compliance Burden| publisher=GAO| date= April, 2010 |accessdate=January 21, 2021}}</ref> Nevertheless, a cautious green card holder (or even work visa holder) wishing to effect a clean and entirely indisputable exit from the US might want to jump through this almost entirely pointless bureaucratic hoop. 

===Disconnecting from the IRS===
{{see also|US tax pitfalls for a US person living abroad#Expatriation tax|Taxation as a US person living abroad#Expatriation tax for losing citizenship or permanent residency|label 1=US tax pitfalls for a US person living abroad § Expatriation tax|label 2=Taxation as a US person living abroad § Expatriation tax for losing citizenship or permanent residency}}

If you surrender your green card, or [https://en.wikipedia.org/wiki/Relinquishment_of_United_States_nationality renounce] US citizenship, after leaving the US, you may be subject to the ''expatriation tax'', discussed [[#Expatriation tax|above]]. Otherwise, if you are in the US on a work visa such as H or L, the process is simpler and less costly.

For your final year in the US, you generally can (and should) chose ''split year'' treatment, so that any income or other financial moves you make after leaving the US are not taxed by the US.<ref name="split year" /> The only time you might consider not using this is if you leave the US very close to or exactly at the end of the calendar year.

===Leaving US accounts behind when you go===

For any US based taxable accounts you hold, your likely best action is to close them and transfer the proceeds to your new country. If you do not do this, you risk substantial US estate taxes if your new country does not have a US estate tax treaty.<ref name="estate tax treaties" />

If you have saved into a US based retirement plan, such as a [[401(k)|401k]] or [[IRA]], you may face challenges managing it once no longer a US resident. For example, some or all of the following:
* US provider restricting your trading, or restricting other account activity
* US provider unilaterally closing your account entirely,
* US provider failing to correctly apply US tax treaty withholding rates,
* US provider withholding US tax on fully tax-free Roth withdrawals,
* US provider incorrectly reporting US tax withholding amounts,
* Perpetual risk of US estate taxes (except if covered by a US estate tax treaty<ref name="estate tax treaties" />),
* Potential home country tax annually on gains inside the pension, and
* Political risk of future US tax laws that are hostile to US nonresident aliens.

Similar difficulties apply to any other US tax-advantaged accounts you might have acquired during your stay in the US, for example a [[Health savings account]] (HSA). While it may be possible to withdraw early from these accounts, there is generally a tax penalty for doing so.<ref>{{cite web| url=https://www.irs.gov/taxtopics/tc557| title=Topic No. 557 Additional Tax on Early Distributions from Traditional and Roth IRAs| publisher=IRS| accessdate=October 15, 2020}}</ref>

If you do not plan on retiring in the US, you should consider very carefully whether it is sensible to participate at all in a 401k, IRA, HSA or any other US tax-advantaged account. It is however usually worthwhile to participate in an employer 401k at least up to the maximum employer match, provided this match more than offsets any early withdrawal penalty you might have to pay.

===FIRPTA and selling your US home===

If you own a home in the US, you should generally sell it before leaving the US, and while you are still a US taxable person. Otherwise, you face a potential large tax penalty from the US ''[https://en.wikipedia.org/wiki/Foreign_Investment_in_Real_Property_Tax_Act Foreign Investment in Real Property Tax Act]'' (FIRPTA). This tax requires US nonresident aliens to pay US income tax rates on any gains in the value of US real estate, and so leaving you in a worse tax position that a similarly situated US citizen. Once you stop being a US taxable person, you become a US nonresident alien.

FIRPTA also applies a sizeable US tax withholding against the full proceeds of any sale of US real estate by a nonresident alien. The rate is generally 15% of the full property sale price, although some exceptions to this may apply.<ref>{{cite web| url=https://www.irs.gov/individuals/international-taxpayers/firpta-withholding| title=FIRPTA Withholding| publisher=IRS| accessdate=October 12, 2020}}</ref> You will have to file a US [https://www.irs.gov/forms-pubs/about-form-1040-nr 1040-NR] nonresident alien tax return to recover any over-withheld amount.
