Vanguard Short Term Bond Index Fund tax distributions
The Vanguard Short Term Bond Index Fund is usually considered a candidate for placement in tax advantaged accounts. The fund is often recommended for the following purposes:
- As a funding vehicle for short-term obligations.
- John Bogle in Bogle on Mutual Funds suggests using short term bond funds for funding an emergency fund. 
- As the fixed income allocation in an investment portfolio. Larry Swedroe  and William Bernstein  advocate using short term bonds for such purposes, although they both point out that investors do not need a mutual fund for purchasing short term treasury securities, so that a short term corporate and/or a short term municipal bond fund can be used in combination with treasury bills and notes.
Investors holding bonds in taxable accounts can compare expected after tax returns of short term municipal tax exempt bond funds, treasury short term bond funds, and corporate short term bond funds to determine which fund provides the highest after tax returns.
The table below summarizes the fund's relation to a number of tax factors.

Historical gains distributions : Modest
Dividends: Taxed at marginal tax rates
The following tables provide long term data on the fund's history of both dividend and capital gains distributions. The second table provides a database of the fund's accounting figures: the annual level of realized and distributed gains; its level of unrealized gains and loss carryforwards; as well as any annual in-kind redemption gains the fund has realized. These figures highlight the level of a fund's tax liabilities. Because both manager turnover of securities inside the portfolio and investor turnover of fund shares can affect the level of gains realization, a third table provides historical turnover ratios.
The following table provides a view of the fund's historical distributions expressed in terms of yields. A portion of the dividend income (column five, Table 2.) is treasury interest, which is not subject to state tax. The fund has distributed short and long term capital gains over its history. Gains distributions tend to track the creation and dissipation of loss carryforwards over interest rate cycles. The 2007 addition of an ETF share class to the fund should help moderate future taxable gains realizations as long as the ETF has sufficient institutional redemption. [notes 1]
The fund has changed tracking indexes once in its history. The transition year of the benchmark change is marked in red shading.

The accounting figures and associated ratios (tables 3 and 4) can help one visualize some of the major determinants of a fund’s tendency to distribute taxable gains. These determining features include:
Turnover: The rate at which a fund manager sells securities within the fund has a major effect on potential gains realization. Bond funds have higher turnover ratios than stock funds, since the bond manager must buy and sell bonds as they mature, and as the manager maintains the maturity and duration structure of the portfolio. The gains or losses on a bond are primarily determined by changes in interest rates, and in some instances, credit quality.
Similarly, fund shareholders' sales flows have major effects on a fund’s distribution tendencies. Net flows into the fund have the following effects:
- Constant inflows allow a fund manager to purchase a wide range of bonds at different prices. The manager can select high basis securities when forced to sell a bond (this may realize a loss). The manager can also select low basis securities when redeeming a bond in-kind (a non-taxable transaction that can remove an unrealized gain out of the portfolio.)
- A large and growing net asset base serves to diffuse any realized capital gains across a large base of shareholders and reduces the per share gain distribution. Large outflows have the opposite effect; any gains realized are spread across a smaller asset base and result in higher per share distributed gains. 
The level of unrealized gains and carryover realized losses in a fund: A fund which defers gains realization accumulates unrealized appreciation, which when distributed, will be taxed; thus the unrealized gain/loss figure shows the potential gain (or loss) that would be realized if the portfolio was to be entirely liquidated. Any loss carryovers a fund possesses can be used to offset future realized gains (carryovers have an eight year expiration period). The third tab on the Table 3. spreadsheet shows the data in percentage of total assets form.
Net sales/redemptions: This statistic reveals whether investors are net buyers or sellers of the fund.
Realized gain/loss: A realized capital gain/loss is an increase (or decrease) in the value of a security that is "real" because the security has been sold by the portfolio manager. The capital gains/losses are "realized" by the fund, and any distributions to the shareholder as a result of realized gains (adjusted for any realized losses) are taxable during the tax year in which the security was sold. Realized losses can be used to offset realized gains in an attempt to reduce taxable gains. If realized losses are higher than realized gains, a fund can "carry forward" these excess losses to offset future gains. In-kind redemption gains are included as gains in this statistic. As these gains are not taxable, they must be deducted from the realized/gain tally to reflect the net gain/loss for the year. (see tax attributes for the net gain computation).
Distributed gains: A net realized gain will be distributed to shareholders as a capital gains distribution.
Unrealized gain/loss: An unrealized capital gain/loss (also called a "paper profit or loss") is an increase (or decrease) in the value of a security that isn't "real" because the security hasn't been sold. When a portfolio manager sells a security, however, the capital gains/losses become "realized" by the fund, and any realized gains (net of any losses) are taxable during the tax year in which the security was sold. Funds with low turnover rates, such as index funds, tend to have more unrealized gains than actively managed funds and are less likely to pass taxable gains on to investors. A fund's unrealized appreciation or depreciation figures are valuable because they can give an idea of whether a fund would need to distribute any gains if all of its securities were sold. Such information may help you determine your potential exposure to taxable distributions. This statistic is volatile, and will increase or decrease depending on market returns.
Loss carryforward: Realized losses can be “carried forward”, over a set span of years, to offset any future net realized gains.
In-kind redemptions: Instead of selling securities, a portfolio manager may elect to distribute securities in-kind to redeeming shareholders. Unlike a sale, an in-kind transfer is not taxable. This technique is frequently used in the ETF creation/redemption process. For institutional redemptions, a portfolio manager can select low-basis securities to transfer (removing the embedded tax liability) from the portfolio.
Vanguard Short Term Bond Index Fund has a high internal turnover rate. Shareholder turnover, on average, has roughly been in line with the fund's duration (suggesting a holding period of between two and three years).
Average net assets: Average net assets are derived from NSAR reports from the EDGAR database.
Redemptions: The dollar amount of fund shares sold by shareholders.
Sales: The dollar amount of fund shares bought by shareholders.
Turnover: The rate at which the fund manager sells securities within the portfolio. The reciprocal of this number reflects the average holding period of the portfolio. Low turnover often results in low capital gains realization.
R/ANA: The redemptions/average net assets (R/ANA) ratio reflects how fund shareholders are turning over their holdings in the fund. It is analogous to the investment manager's turnover ratio.
R/S: The redemption/sales ratio (R/S) illustrates whether investors are net buyers or sellers of the fund. A ratio of less than 1 means that investors are net purchasers of the fund. A ratio more than one means investors are net sellers of the fund. The R/ANA and R/S ratios, viewed together, can signal market timing activity within a fund. For example a fund showing an R/ANA ratio of 400% and an R/S ratio of 1 (equal buys and sells) is likely being market timed by fund shareholders.
Mutual fund distributions will be taxed according to the tax laws governing the investment over the holding period of the investment, which are subject to change. The actual tax imposed will depend upon each individual's tax rate and the timing of purchases and sales. The federal tax rates applicable to mutual fund distributions and investor sales of securities for the period 2013 onward are outlined below. Keep in mind that investment income may also be subject to state and local taxation.
- Short-term capital gains distributions are made from realized gains on securities held for one year or less. Short-term gains are taxed at ordinary income tax rates up to 39.6%. Mutual fund short-term gain distributions are included in a fund's ordinary dividend distribution; therefore, capital losses may not be subtracted from these distributions when computing taxes.
- Long-term capital gains distributions are made from realized gains on securities held for more than one year. Long-term gains are taxed at 0% for taxpayers in the 10% and 15% tax brackets, at 15% for taxpayers in the 25%, 28%, 33%, and 35% tax brackets, and at 20% in the 39,6% tax bracket. They are reported on tax Schedule D along with any other capital gains, and can be reduced by capital losses.
- Qualified dividends are the ordinary dividends [notes 3] that are subject to the same tax rate that applies to long-term capital gains. They should be shown in box 1b of the Form 1099-DIV you receive.
- When you sell at a loss you will either offset capital gains which would have otherwise been taxed at your capital gains rate or you will offset income (up to $3,000 maximum per year) which would have otherwise been taxed at your marginal income tax rate, or both. If you offset capital gains that would have otherwise not been taxed at all (because your capital gains tax rate is 0%) then this part of the tax loss harvest may be an outright loss.
- The Affordable Care Act imposes a Medicare surcharge of 3.8% on all net investment income (NII) once the taxpayer's adjusted gross income exceeds $200,000 (single) or $250,000 (married); while this tax is not part of the income tax, it has the same effect on investors as a higher tax rate. The NII tax begins to apply to individuals falling in the 33% tax bracket. Thus the top effective marginal tax rate is 23.8% on qualified dividends and long-term gains, 43.4% on ordinary investment income.
|Taxable income up to this level||Tax rate|
|Single||Married filing joint||Head of Household||Ordinary income||Long-term gains and qualified dividends|
In addition, there is a 3.8% Medicare tax rate on investment income in excess of an adjusted gross income of $200,000 ($250,000 for married filing jointly), and 0.9% on salary and self-employment income in excess of this level.
- Because ETF share classes reduce transaction costs and bring tax benefits to the fund portfolio regardless of share class turnover (which can be quite high) we provide separate R/ANA and R/S ratios for the ETFs. We must approximate the average net asset figure for ETFs. One should also note that Vanguard includes share class conversions (investor/ETF) in the sales and redemptions totals for the fund. Vanguard does not quantify conversions. These non-transaction conversions inflate the reported mutual fund shareholder ratios. The fund has experienced steady growth in ETF shares.

- Fairmark says:
A portion of your ordinary dividend may be nonqualified because it can include items like these:
- Taxable interest. When a mutual fund receives taxable interest, the income gets paid out as a dividend. It's a dividend when it goes out of the mutual fund, but it wasn't a dividend when it came into the mutual fund, so it can't be a qualified dividend.
- Nonqualified dividends. Your mutual fund may receive dividends that are nonqualified. For example, the mutual fund may sell shares just 35 days after buying them, but after receiving a dividend. The mutual fund has to hold the shares at least 61 days to have a qualified dividend. Any amount the mutual fund receives as a nonqualified dividend gets paid to you as a nonqualified dividend.
- Short-term capital gain. When a mutual fund has a short-term capital gain, it pays this amount to the mutual fund shareholders as an ordinary dividend.
- Holding mutual fund shares less than 61 days. You should also be aware that any dividend you receive on mutual fund shares held less than 61 days is a nonqualified dividend, even if the mutual fund reports that amount to you as a qualified dividend. You don't have to buy the shares 61 days before the dividend is paid, but the total amount of time you hold the shares (including time before and after the dividend) has to be at least 61 days.
Almost all of the dividends distributed by Equity REITS come in the form of non-qualified dividends. Non-qualified dividends are taxed at marginal income tax rates.
