Nonresident alien investors and Ireland domiciled ETFs

This page intends to discuss why it may be better for a nonresident alien (NRA in US IRS terms) with no US tax treaty to invest in Ireland-domiciled exchange-traded funds (ETFs) as opposed to the popular US-domiciled mutual funds discussed often by US-based investors.

Please note that for Europeans it has become difficult to buy the us-domiciled funds due to 2018 European MIFID and PRIIPS regulations.

This article will assume the rate of 30% for any dividend withholding calculations in absence of a dividend tax treaty.

US tax treaties
Depending on your country of residence, you may be able to benefit from a US tax treaty for lower rates and higher exemptions. If you do, some parts of this article may not apply directly as you may be able to benefit from lowered treaty rates.

List of treaties can be found at United States Income Tax Treaties - A to Z.

Why invest in Ireland-domiciled ETFs as an NRA?
A few reasons for preferring Ireland-domiciled ETFs over US-domiciled ETFs:
 * Ireland-domiciled ETFs can benefit from the US-Ireland tax treaty rate of 15% on dividends and 0% on interest paid to Irish corporations, instead of 30% for non-treaty NRAs.
 * Double tax withholding for US-domiciled ETFs holding foreign securities. The US-domiciled ETF pays withholding to international governments, then the US levies 30% off of the remaining distributed dividends.
 * Complex and constantly changing US tax laws affecting NRAs. Leave it to iShares and Vanguard Dublin to deal with those.
 * Non-residents of Ireland are not liable to Irish gift tax or inheritance tax.
 * Availability of accumulating funds.

Caveats of investing in Ireland-domiciled ETFs?
Some of the downsides:
 * US-domiciled ETFs often have lower expense ratios.
 * US-domiciled ETFs usually have narrower bid/ask spreads.
 * Most Ireland-domiciled USD denominated ETFs have rather low daily trading volumes. See: Understanding ETF liquidity at ETF.com.
 * ETF options are limited but sufficient to build a Bogleheads-style lazy portfolios.
 * Depending on your broker, buying Ireland-domiciled ETFs usually costs more in transaction fees. Beware that next to transaction costs, brokers can have annual custody fees.
 * Many EU-domiciled ETFs are synthetic. See EU investing for more information.
 * The taxation mentioned here is only applicable for non-Irish residents. For people residing in Ireland another set of rules applies.

No Irish dividend tax withholding for Ireland-domiciled ETFs
Based on a few sources, Ireland does not withhold any taxes on capital gain or dividends paid by Ireland-domiciled UCITS ETFs for non-residents of Ireland. That seems to be true for Vanguard and iShares Dublin.

According to Dillon Eustace law firm:

"Taxation of investors from the perspective of the investment funds (Non-Residents):

''As outlined above, Irish investment funds are not subject to any taxes on their income (profits) or gains arising on their underlying investments. In addition, there are no Irish withholding taxes in respect of a distribution of payments by investment funds to investors or in relation to any encashment, redemption, cancellation or transfer of units in respect of investors who are neither Irish resident nor ordinarily resident in Ireland, provided the fund has satisfied and availed of certain equivalent measures or the investors have provided the fund with the appropriate relevant declaration of non-Irish residence.''"

According to iShares UK:

"Distributions from Exchange Traded Funds (ETFs) such as Dublin-domiciled iShares are exempt from Irish withholding tax by virtue of the shares issued by Dublin-domiciled iShares being settled via a recognised clearing system (Crest)."

A reply received from Saxo Bank customer support dated March 2015:

"Our corporate actions team replied that on VWRL there has previously been 0% tax. On Irish ETFs in general they can’t give an answer – it may be different on different ETFs."

Double tax withholding
From a Canadian perspective, according to PWL Capital:

"Investors are potentially subject to withholding taxes levied by the countries where the stocks are domiciled, whether that is the US, developed markets outside North America (western Europe, Japan, Australia), or emerging markets (China, Brazil, Taiwan). We refer to this as Level I withholding tax.

''When international stocks are held indirectly via a Canadian-listed ETF that holds a US-listed ETF, investors may also be subject to what we've called Level II withholding tax. This is an additional 15% [30% if no tax treaty] withheld by the US government before the US-listed ETF pays the dividends to Canadian investors.''

''You can think of Level I foreign withholding tax like a departure tax you pay when taking a direct flight to Canada from a foreign country (including the US). Level II tax is like a second departure tax you pay when an overseas flight to Canada has a layover in the US.''"

Estimating Level I tax withholding paid by US-domiciled funds
According to the same PWL Capital white paper, the following are the percentages of tax withholding paid by different types of US-domiciled ETFs

&dagger; Note that iShares MSCI EAFE ETF (EFA) excludes the US. You can use that number to approximate Level I taxes for the ex-US developed markets portion of the fund in question. If the US-domiciled fund you are analyzing has 60% US stocks vs 40% ex-US developed markets, the Level I tax withholding will be 0.40 * 7.5% = 3.0% approximately.

Estimating Level I tax withholding paid by Ireland-domiciled funds
Using annual reports of the most traded funds from iShares and Vanguard, the following is the resulting Level I percentages leaked by funds per percent dividend yield. Those figures were calculated for this wiki post. If you find other sources online confirming, please update and reference accordingly.

Keep in mind that each index provider (MSCI/FTSE) has a different definition of "Developed Markets" and "Emerging Markets". Different indices have different allocations of those markets, too.

Calculating tax withholding as a ratio
To better compare different ETFs we can convert the tax withholding percentages into a total annual approximation, let's call it the Tax Withholding Ratio (TWR). This makes it easily comparable to the expense ratios found on funds' fact sheets. See references for more about this method.

To calculate the Tax Withholding Ratio (TWR), we need four pieces of information:
 * L1TW: Percentage of tax withholding paid by the fund on the dividends distributed by the underlying international securities held (Level I). This can be estimated using each fund's annual report, by dividing "Non-reclaimable withholding tax" by "Dividend Income".
 * L2TW: Percentage of tax withholding on dividends the individual pays (Level II). If you are a non-treaty NRA investing in US-domiciled ETFs, that number is 30%. If you are investing in Ireland-domiciled ETFs and you do not reside in Ireland, you do not have to pay any Irish tax withholding.
 * YIELD: Annual yield of the fund. As you cannot know the amount of future dividends in advance, an approximation based on historical values (gross before withholding was paid) should be sufficient. Dividend yield is used in the formula as the Level I taxes are paid on dividends received by fund.
 * TER: The fund's Total Expense Ratio. Can be obtained from a fund's KIID document.

The math after that is rather simple: TWR = (YIELD &times; L1TW) + ((YIELD &times; (1 - L1TW) - TER) &times; L2TW) The first part calculates the Level I leakage. The second part uses the remaining dividend, deducts the fund's TER then applies the individual's Level II tax to the remaining sum.

You can now add our TWR to the fund's published expense ratio to get a comparable total ratio paid annually. Note that this makes abstraction of the dividend tax that the individual investors pays to his resident-country on the dividends that he actually receives.

Example calculation for S&P 500 ETFs
Let us compare the US-domiciled Vanguard S&P 500 ETF (VOO) vs Ireland-domiciled Vanguard S&P 500 UCITS ETF (VUSA).

Vanguard S&P 500 ETF (VOO): TWR for VOO = 0 (no L1 withholding) + ((2.0% * (1 - 0) - 0.05%) * 0.30) = 0.59%
 * L1TW = 0%, as it is US-domiciled, holding US securities
 * L2TW = 30%, no-tax-treaty NRA rate
 * YIELD = 2.0%, estimated as we need it for comparison purposes, not exact dollar calculations
 * TER = 0.05%

Vanguard S&P 500 UCITS ETF (VUSA): TWR for VUSA = (2.0% * 0.15) + 0 (no L2 withholding) = 0.30%
 * L1TW = 15%, as it is Ireland-domiciled, holding US securities
 * L2TW = 0%, no Irish tax withholding on UCITS funds
 * YIELD = 2.0%, estimation
 * TER = 0.07%

L1TW for VUSA can be also calculated using its annual report. For 2014, Foreign Withholding Tax (7,721,652) divided by Dividend Income (52,371,805) = 14.74%. TedSwippet explains that it's not 15.0% on the dot due to a 2.5% REIT allocation, which may distribute dividends or capital gains at different rates than the US treaty rate of 15% for dividends. A tax drag differing from the treaty rate may for instance be caused by foreign companies in an index, capital gains being taxed differently than dividends and REITs can recharacterize distributed dividends as return of capital, which is not to be taxed.

Including the funds' expense ratios: VOO's total cost is 0.64%, while VUSA's total cost is 0.37% for a NRA without tax treaty access.

Example calculation for FTSE World ETFs
Let us compare the US-domiciled Vanguard Total World Stock ETF (VT) vs Ireland-domiciled Vanguard FTSE All-World UCITS ETF (VWRL).

Vanguard Total World Stock ETF (VT): &dagger; Ratios of US/EM/DM obtained from VT's Vanguard.com portfolio page. TWR for VT = (2.0% * 0.039) + ((2.0% * (1 - 0.039) - 0.17%) * 0.30) = 0.07794 + 0.52562 = 0.60%
 * L1TW &dagger; = 0% * 52% (US) + 9% * 10.8% (Emerging Markets) + 39% * 7.5% (ex-US developed) = 3.9%
 * L2TW = 30%, no tax treaty NRA rate
 * YIELD = 2.0%, estimation as we need it for comparison purposes, not exact dollar calculations
 * TER = 0.17%

Vanguard FTSE All-World UCITS ETF (VWRL): TWR for VWRL = (2.0% * 0.103) + 0 (no L2 withholding) = 0.21%
 * L1TW = 10.3%
 * L2TW = 0%, no Irish tax withholding on UCITS funds
 * YIELD = 2.0%, estimation
 * TER = 0.25%

Including the funds´ expense ratios: VT's total cost is 0.77%, while VWRL's total cost is 0.46% for a no-tax-treaty NRA. Note that as allocation to countries changes over time, tax drag will change over time as well. Note that as yield changes over time, tax drag will change over time as well.
