Wealthfront Tax-Loss Harvesting
This white paper summarizes the motivation, design, and historical results of Wealthfront’s Tax-Loss Harvesting service. Our actual results demonstrate that Tax-Loss Harvesting significantly improves the tax efficiency and ultimately the after-tax return of Wealthfront’s taxable portfolios. But more importantly Tax-Loss Harvesting typically more than pays for our advisory fee for almost all our clients. We believe Tax-Loss Harvesting should be a fundamental component of most every individual’s investment management strategy.
What is Tax-Loss Harvesting?
Tax-Loss Harvesting is a way to make an investment portfolio work even harder – not just in generating investment returns, but by also generating tax savings.
Tax-Loss Harvesting (TLH) works by taking advantage of investments that have declined in value, which is a common temporary occurrence in broadly diversified investment portfolios. By selling investments that have declined below their purchase price, a tax loss is generated – which can be used to offset other taxable items, thus lowering the investor’s taxes.
What’s more, any investment sold in this manner can be replaced with a highly correlated alternate investment, such that the risk and return profile of the portfolio remains unchanged, even as tax savings are created. These tax savings can even be reinvested to further grow the value of the portfolio.
Wealthfront developed software to make Tax-Loss Harvesting available to all our clients. Implementing Tax-Loss Harvesting in software makes it possible to look for harvesting opportunities on a daily basis, which could result in significantly greater benefit than what could be achieved from the manual end-of-year approach typically taken by traditional financial advisors.
Tax-Loss Harvesting is a Tax-Deferral and Tax Rate Arbitrage Strategy
Tax-Loss Harvesting can be used to defer tax liabilities, not avoid them. As a result it has very little value if applied over a short investment horizon (i.e. less than two years), but can be extremely valuable if executed over a long period of time. This is best demonstrated through an example that describes the benefits under two holding period scenarios:
Scenario 1 (one-year investment horizon)
Assume you buy 1,000 shares of ETF A at a price of $100 per share for a total investment of $100,000. A few months later, the market declines to the point ETF A is now worth $90 per share, or $90,000 total. You sell all your shares of ETF A and replace it with an equivalent amount of ETF B (500 shares at $180 per share), which tracks an index that is highly correlated to the one ETF A tracks. You now own a $90,000 position in ETF B and have realized a $10,000 short-term loss for tax purposes. ETF B closes the year at $200 per share at which time you sell your entire position. Your sale of ETF B generates a $10,000 short-term gain which balances your $10,000 short-term loss. In this case harvesting the loss in ETF A generated no value.
Scenario 2 (five year investment horizon)
This scenario is much more complex and requires the table below to follow.Let’s assume you started off with the exact same $100,000 investment in ETF A and a few months later it declined 10% at which time you harvested the loss and replaced it with an equivalent amount of ETF B. Once again ETF B appreciates to $100,000 by the end of the year, but this time you don’t liquidate your account. As a result your net realized short-term capital loss on this position for the year is $10,000, which generates a $4,000 tax savings when applied against your income and other realized gains under the assumption of a combined federal and state tax rate of 40%. If you reinvest that tax savings your end-of-year portfolio value is now $104,000. The next year your portfolio appreciates 1.9% to $106,000. The following year your portfolio declines in value by 11.7% to $93,600 at which time you once again harvest a loss of $400 (on your previously reinvested tax savings), which generates a $160 ($400 x 40%) tax savings for that year. You reinvest the $160 and the following two years your portfolio is flat and increases to $104,160 respectively. At the end of year 5 you liquidate the portfolio. At this point you have to pay the tax due on the $10,000 appreciation of ETF B and the $400 loss in year three that is recaptured. However, this time the gains are long-term capital gains, so you pay the lower 25% combined federal plus state tax rate, which results in a negative $2,600 cash flow ($10,400 long-term capital gain x 25%).
As you can see Scenario 2 results in a significant overall tax savings even though all of the realized losses are ultimately balanced with an equivalent realized gain. The positive economic benefit that results from this scenario can be attributed to the reinvestment of the tax savings and the significant difference in tax rates between short-term capital gains and long-term capital gains.
The value of Tax-Loss Harvesting is maximized if your portfolio is never liquidated. This is possible even when you expect to employ your portfolio for your retirement needs. For example, you can place your appreciated assets in a Charitable Remainder Trust (CRT) or similar vehicle – generating income for yourself in retirement while donating the remainder of your portfolio to a non-profit organization of your choice. Because nonprofits are not taxed, they are able to sell your highly appreciated assets and generate retirement income for you with no regard to the cost basis or tax liability of those assets.
Similarly, you can choose to pass on all or a large percentage of your portfolio to your heirs. Because your heirs receive a step-up in basis for the portfolio on your death, they are again able to take full advantage of the portfolio’s value without regard to its low cost basis or its tax liability.
Finally, instead of fully liquidating your portfolio in retirement, you can liquidate only a part of the portfolio and pass on or donate the rest. Such partial liquidation approaches, when done tax-efficiently, can again allow you to keep most of the gains of Tax-Loss Harvesting.
Who should use Tax-Loss Harvesting?
Tax-Loss Harvesting is generally valuable for all investors with taxable accounts who have a long-term investment horizon. Harvested losses can be applied to offset both capital gains and up to $3,000 in ordinary income annually. Furthermore, any losses that cannot be applied in a given tax year can be carried over indefinitely to offset future income and capital gains.
Of course, Tax-Loss Harvesting is especially valuable for investors who regularly recognize short-term capital gains. These gains can come from the sale of company stock, real estate, or just about any investment. Tax-Loss Harvesting can even be used to minimize the gains associated with liquidating a portfolio to move to a new financial advisor.
Wealthfront’s Tax-Loss Harvesting service
For taxable accounts, Wealthfront offers the Wealthfront Tax-Loss Harvesting service for no additional charge. We monitor your portfolio daily to look for opportunities to harvest losses on the ETFs that represent each asset class in your portfolio. Under the right circumstances, we will sell one of your ETFs that is trading at a loss and replace it with an alternative ETF that tracks a different, but highly correlated index to maintain the risk and return characteristics of your portfolio. We will then hold that alternative ETF in your portfolio for a minimum of 30 days to avoid wash sales, which are described below. We will not sell the alternative ETF until it can be sold for a loss, which will generate additional Tax-Loss Harvesting benefit.
The following two tables list the primary and alternative ETFs we use to represent each asset class, their associated indexes, expense ratios and correlations in weekly returns between the primary and alternative ETFs estimated using the longest common available period of data ending on October 31, 2020.
Our asset class level Tax-Loss Harvesting strategy uses a cost-benefit analysis framework to evaluate potential harvesting opportunities for each ETF lot currently trading below its cost basis. Cost is measured in two ways:
Trading Cost: this is the cost of selling the primary ETF and buying the secondary ETF. The trading cost for each ETF is simply the estimated bid-ask spread. Wealthfront clients never incur any commissions from trading.
Opportunity Cost: This is not a true “cost”, but an estimate of the expected future harvesting benefit, which is modeled by assessing the likelihood that a better harvesting opportunity is available by waiting longer to perform the Tax-Loss Harvesting trade (and thus potentially capturing a larger decline). Expected return and volatility of each asset class are used as parameters in this estimate.
The benefit of a tax-loss harvest is calculated by multiplying the potential realized capital loss incurred from selling an ETF times either the short-term or long-term capital gains tax rate, depending on the ETF’s holding period.
When the expected benefit outweighs both types of costs, we execute two trades:
- We sell the specific ETF lot to recognize a loss, and
- We purchase the same dollar amount of a similar, but not substantially identical, ETF (see Table 2 for the alternative ETFs we use for each asset class) to maintain the desired asset class exposure.
We evaluate every ETF tax lot in each eligible account every day, and execute trades when our system identifies the necessary conditions.
Wash sale management
One complexity in executing our Tax-Loss Harvesting strategy is the management of wash sales. Normally, you recognize a loss when you sell a security for less than its cost basis. However, if you buy the same or substantially identical security within 30 days of the sale, the wash sale rule applies and you are not allowed to claim the tax benefit immediately.
It should be noted that a wash sale does not completely eliminate the benefit of harvesting a loss, but only temporarily reduces that benefit by the amount of the wash sale itself. For example, if you sell 1,000 shares of a particular ETF to harvest a loss, but happen to buy 10 shares of the same ETF within 30 days, you will still be able to take advantage of the harvested loss on 990 of the 1,000 shares originally sold – as only 10 shares are actually subject to the wash sale rule in this situation. In this situation, the disallowed loss from the 10 shares where the wash sale rule applied is added to the cost basis of the 10 new shares you purchased. You can get the tax benefit of the loss when you sell the 10 new shares.
In the case of applying Tax-Loss Harvesting to a portfolio of index based ETFs, you need to use two securities that track different indexes to avoid violating the substantially identical clause of the wash sale rule. Swapping an ETF with another that tracks the same index from a different issuer (i.e. Vanguard vs. Schwab) would violate the substantially identical rule. As a result, you’ll see that the alternative ETFs presented in Table 2 track different, but highly correlated indexes from the recommended primary ETFs in Table 1.
The risk of a wash sale increases with the number of rebalancing trades made as part of the ongoing management of a portfolio. If not carefully managed, a security sold to harvest a loss might be re-purchased for another reason (change in asset allocation, rebalancing, dividend reinvestment, or deposit) and the tax benefit could be disallowed, defeating the purpose of Tax-Loss Harvesting. We carefully manage the interaction and timing of trades within our portfolio management service to help avoid wash sales.
The situation becomes more complex in the case of multiple accounts, as the wash sale rule applies to all of an investor’s accounts including IRAs – as well as spousal accounts for joint filers. For example, if an investor sells a security in her personal non-retirement account and repurchases it within 30 days in her IRA, it’s considered a wash sale; if her spouse purchases the same security within 30 days in his personal non-retirement account, it’s also viewed as a wash sale. Wealthfront monitors all the accounts it manages for each client to avoid any transactions that might trigger a wash sale. Additionally, clients can link a spousal account to ensure that wash sales are not generated across accounts belonging to the same taxable household. We urge all our clients to consult with their tax advisors to confirm that our Tax-Loss Harvesting strategies are right for them.
Measuring Tax-Loss Harvesting
A basic measure we use to quantifyTax-Loss Harvesting is called Harvesting Yield. This measures the quantity of harvested losses (both short- and long-term) during a given period, as a fraction of the portfolio’s value.
- STCL is the short-term net capital loss realized
- LTCL is the long-term net capital loss realized
- PortfolioBeginningBalance is the value of the portfolio at the beginning of each year
To arrive at annual figures, we sum the Harvesting Yield for each day within a given year.
Economic Value of Tax-Loss Harvesting
The economic value of Tax-Loss Harvesting depends on a broad range of assumptions describing the specifics of the client’s tax situation. For example, (a) the availability of taxable income which may be offset with harvested losses (short-term capital gains, long-term capital gains, and up to $3,000 in ordinary income per year); (b) the tax rates (both federal and state) applicable to the income being offset; (c) the client’s tax rate at the time the portfolio used to generate the tax losses is liquidated (which can change due to changes in tax policy or changes in income); (d) the client’s investment horizon; (e) the rate of return on reinvested tax savings; and (f) the frequency with which you add deposits to your portfolio.
Tax Savings and Liabilities
The economic value of the harvested losses can be measured using the difference between the tax savings generated today (due to the ability to offset taxable income items) and the present value (PV) of the increased tax liability in the future (due to the decreased cost basis of the instruments used to harvest the tax losses). The Tax Savings today are given by the following formula:
- Amount Offset is amount of tax losses utilized
- Current Tax Rate is the combined federal + state tax rate applicable to the taxable item being offset (ordinary income, short-term capital gains, or long-term capital gains) adjusted for the deductibility of state taxes at the federal level.
And the present value of the increased tax liability is represented by the following formula:
- Amount Offset is amount of tax losses utilized
- Future Tax Rate is the long-term capital gains rate prevailing at liquidation
- Discount Factor is a discount applicable to payments occurring in the future to account for the time value of money. It is given by (1 + r)-T, where r is the assumed annual rate of return on the reinvested tax savings, and T is the number of years until projected portfolio liquidation.
The client benefits from the deferral of taxation, as well as the difference between the tax rates applicable today and the lower, long-term capital gains rate, which will apply to the portfolio gains at that time. In some instances, described earlier, clients may even be able to avoid taxation altogether.
To illustrate the economic value of Tax-Loss Harvesting, let’s consider an example where a client has an investment portfolio worth $100,000 and has harvested $6,000 in tax losses in a given year, reflecting a Harvesting Yield of 6.0%. We will show later that this Harvesting Yield is slightly lower than the cross-vintage average realized experience of clients with risk score 8.0 taxable portfolios, the most commonly selected risk score among our clients. Further suppose that the client has generated $1,000 in short-term capital gains (either at Wealthfront or elsewhere), and $2,000 of long-term capital gains (again either at Wealthfront or elsewhere). The $6,000 of harvested losses could be used to offset $1,000 of short-term capital gains, $2,000 of long-term capital gains, and $3,000 of ordinary income. The ordinary income offset is limited to $3,000 per year, and is applied only after all net capital gains have been offset.
To give a sense of the range of economic benefits generated, we consider two clients differing in their tax burden. The client subject to the lower tax burden faces a combined tax rate of 25% on ordinary income and short-term capital gains, and 15% on long-term capital gains today. The client subject to the higher tax burden faces a combined tax rate of 45% on ordinary income and short-term gains, and 25% on long-term capital gains. We’ll assume that each client intends to completely liquidate the portfolio in 20 years, at which point their gains will be subject to taxation at long-term capital gains rates, equal to those prevailing today (15% for the low tax burden client, and 25% for the high-tax burden client). For the discount rate, we use 8%, which is slightly lower than the average return of clients invested in taxable accounts with a risk score of 8.0, our average and most common risk score. Table 3 below computes the tax savings, present value of the increased tax liability, and the net economic benefit to each client type.
When expressed as a fraction of the portfolio value, this economic benefit amounts to an incremental return of 1.11% in the current year for the client facing the low tax burden, and an incremental return of 1.98% for the client facing the high tax burden. Both of these values compare very favorably with Wealthfront’s annual advisory fee of 0.25%.
In these examples, the client was able to use the full amount of the harvested losses ($6,000). If the client did not have sufficient taxable gains or remaining ordinary income credit in a given year to take advantage of the full amount of the harvested losses, the excess losses are carried forward indefinitely for use in subsequent years.
Finally, it is worth pointing out that an increase in future tax rates may decrease or increase the economic benefit of the harvested losses, depending on when the losses are realized. If tax rates were to double between the time of the harvest and time of liquidation, to 30% and 60% for the client with low tax burden and high tax burden, the economic benefits would decrease to 0.91% and 1.66% of the portfolio value – still large multiples of Wealthfront’s annual advisory fee. However, if tax rates rise over time, losses harvested from later deposits will have a higher initial tax benefit. The later losses will be more likely to maintain a larger difference between the tax rate applied at the time the loss is harvested and the time of final liquidation.
As you can see, the precise details of the computation determining the value of Tax-Loss Harvesting are significantly affected by the particulars of each client’s tax situation. In general, the greater the wedge between the tax rate applicable to the income items being offset today and the long-term capital gains rate applicable when the portfolio is liquidated, the greater the economic benefit of Tax-Loss Harvesting. Similarly, the longer the time between the client’s investment horizon, and the higher interest rates, the lower the present value of the future tax liability, and thus, the greater the benefit of Tax-Loss Harvesting.
Tax-Loss Harvesting can add more value to clients who make regular deposits into their accounts compared to ones who make a single deposit when the account is opened and never add any more funds. That’s because losses are more likely to be found in recently-purchased holdings that have not had as much time to appreciate. If you add more deposits, you have more recently purchased holdings.
An example can help make this more clear. Let’s say two investors both choose a portfolio that returns 8% per year, and that the assets in the portfolio always yield 5% in losses in the first year after purchase, and no more losses after the first year. Investor A makes a single deposit of $10,000, and no more after that. This investor harvests $500 in losses in the first year, but no losses in subsequent years. Investor B makes an initial deposit of $10,000 and follow-on deposits of $2,500 at the beginning of each subsequent year. This investor harvests $500 in losses in the first year, and then $125 in losses in each following year. The table below shows the portfolio value and total losses harvested for each investor over a 10-year period. At the end of 10 years, Investor A has an average annual harvesting yield of 0.50%, while Investor B has an average annual yield of 0.94%.
This section examines the loss-harvesting results experienced by Wealthfront clients since the launch of the service in October 2012.
Realized Harvesting Yields
In order to analyze the harvesting yields realized by clients, we aggregate clients into cohorts based on the year in which they first started using TLH (i.e. the client “vintage”) and their risk score. The vintage is a fixed client characteristic, but clients can move across risk score groupings based on their risk score on a given day in the sample. On each day, we compute the aggregate losses harvested within portfolios of clients belonging to a given cohort, sum these losses across clients in the cohort, and divide them by the aggregate portfolio balance of clients belonging to the cohort, to obtain that day’s Harvesting Yield. We then compute an annualized “since inception” Harvesting Yield for each cohort, by averaging the daily Harvesting Yield figures, and multiplying by 252 (the number of trading days in a year). The values for the 2020 cohort are reported unannualized, since a complete year of Tax-Loss Harvesting data is not yet available. The annualized Harvesting Yields for each vintage by risk score cohort are reported in Table 3. The data include all tax losses harvested through November 30, 2020.
Within any given vintage year, the realized Harvesting Yield generally increases with portfolio risk score, because higher risk levels result in higher allocations to more volatile asset classes (such as stocks) and will thus result in more harvesting opportunities. This pattern plays out across risk scores within a vintage year, as well as in the cross-vintage average figures, reported in the column titled “AVG.” That being said, you should not increase your risk level to get more Tax-Loss Harvesting benefit, because it is more likely to lead to a level of portfolio volatility that will cause you to prematurely liquidate and lose money (see DALBAR analysis).
The second pattern that can be observed in client data is that the Harvesting Yields can vary substantially across vintages for a given risk score. This is because each vintage experiences a different set of market conditions, which affect the scope of the harvesting opportunities. For example, the periods in which markets experience large peak-to-trough swings, generally create more Tax-Loss Harvesting opportunities than placid periods. The 2020 vintage is the most striking example of this. Clients who made their first deposits in early 2020 were able to harvest large amounts of losses when markets plunged during the onset of the COVID-19 pandemic.
The last two rows in the table provide summary statistics indicating the scope of harvesting opportunities. The “Market Volatility” row shows the annualized volatility of the VOO ETF, which tracks the S&P 500, from the first trading day of each year through the final date in our sample (November 30, 2020). The “Maximum Market Drawdown” row reports the maximum loss that an investor in the VOO ETF would have sustained between the first business day of each vintage and the last calendar day of our sample. For example, a maximum drawdown of 0% for the 2013 vintage means that at no point subsequent to the initial investment (made on January 2, 2013) through the end of the sample was VOO below its value on the first business day of 2013. Similarly, for the 2016 vintage, the largest cumulative drop experienced by an investor who made their initial investment on January 4, 2016 (the first business day of 2016) through the end of the sample was -10.29%.
Within each risk score, there is a strong negative correlation between the annualized harvesting yields realized by the different cohorts and both the volatility and the maximum drawdown realized by the market over the corresponding time period. Importantly, even for vintages where markets were broadly trending up (i.e. the maximum VOO drawdown was zero), our Tax-Loss Harvesting service can still take advantage of intermediate market swings to harvest losses. This reflects a meaningful advantage of Tax-Loss Harvesting that monitors for losses daily relative to more traditional approaches, such as year-end Tax-Loss Harvesting.
Value Of Tax-Loss Harvesting Relative To Our Fee
Next, we examine the ability of Tax-Loss Harvesting to pay for itself, by providing tax benefit in excess of Wealthfront’s annual 0.25% advisory service fee (which also includes automatic rebalancing, dividend reinvestment, and tax-efficient withdrawals). In this analysis, we estimate tax rates for each client based on the income, marital status, and state of residence provided during the account signup process. The tax rates and income brackets we use are the ones effective for the 2020 tax year. For each client, we calculate the total amount of long-term and short-term losses harvested during the lifetime of their account, and use the appropriate estimated tax rates to compute a total estimated tax benefit. We then compare this total benefit to the total estimated advisory fee paid by the client, using an annualized rate of 0.25% applied to each day’s total account balance.
Calculating the tax benefit of harvested losses requires some assumptions beyond the tax rate levels. We use the following methodology:
- Long-term losses are multiplied by the client’s estimated long-term capital gains tax rate. This is the sum of the federal capital gains rate and marginal state income tax rate.
- Short-term losses are multiplied by the client’s estimated short-term capital gains rate. This is the sum of their marginal federal and state income tax rates.
The analysis assumes full utilization of losses to offset gains. In reality this may not be the case – some may rarely make withdrawals from their accounts and may not have any capital gains to offset. However, we should remember that excess losses after all capital gains have been offset can be used to offset up to $3,000 of income per year, and any excess still remaining after that can be carried over indefinitely into the future. Income is taxed at a higher rate than long-term capital gains, so losses are more valuable when used to offset income as compared to long-term gains.
We find that the median ratio of tax benefit to fee is 4.7x, meaning that for a typical customer, our Tax-Loss Harvesting service is paying for itself more than four times over and more than 96% of clients who used Tax-Loss Harvesting received more in tax benefit than they paid in fees. The small minority of clients whose tax benefit has not exceeded their total fee tend to be invested in lower-risk portfolios and live in states with low or no taxes.
Assessing Our Tax-Loss Harvesting Efficiency
To assess the efficacy of our approach toTax-Loss Harvesting, we compared our annual Harvesting Yield to the theoretical maximum Harvesting Yield possible in a given year. We use backtested data to perform the analysis because it would be exceptionally difficult to use actual data for Wealthfront given all the idiosyncrasies of our individual client accounts. The theoretical maximum Harvesting Yield can be computed by performing a backtest where wash-sale rules and transaction costs are ignored, so losses can be harvested every day, until the bottom of every downturn since the initial purchase.
We measure the effectiveness of our Tax-Loss Harvesting service using the Harvesting Efficiency Ratio, defined as follows:
For the purposes of the backtest we assume that an investor initially deposits $100,000 and then deposits $10,000 each quarter thereafter. The rate at which funds are being added equals 40% (= 4 * $10,000 / $100,000) in the first year and 30% (= 4 * $10,000 / $140,000) in the second year, which is more conservative than the historically observed add-on rate of our clients, who are young and in the wealth accumulation phase of their lives. The backtest period runs from January 2000 through December 2020.
We subdivide the backtest period into twelve overlapping, 10-year subperiods. Figure 1 displays the Harvesting Efficiency Ratio for our Tax-Loss Harvesting service for each of the 10-year subperiods for a client invested in a Risk Score 8.0 taxable portfolio. We present detailed results for the Risk Score 8.0 portfolio as this is the most commonly chosen risk score among our clients. On average, our Tax-Loss Harvesting service captured 83% of the theoretical maximum Harvesting Yield. As you can see, the Harvesting Efficiency Ratio of our service is remarkably stable across the five-year subperiods, ranging between 73% and 88% of the theoretical maximum.
This result carries over to all portfolios independent of their Risk Score. We repeated the above analysis for taxable portfolios with Risk Scores ranging from 1.0 to 10.0, and in Figure 2 reported the average Harvesting Efficiency Ratio achieved by each algorithm across the 10-year subperiods. Across the various portfolios, Tax-Loss Harvesting achieved a Harvesting Efficiency Ratio of 79%.
These results lead us to believe there is very little additional benefit that can be gained through additional tweaks to our Tax-Loss Harvesting service. Although small improvements are theoretically possible, there’s unlikely to be another asset class-based Tax-Loss Harvesting algorithm that’s significantly better than our implementation. This assertion is backed up by experiments we ran testing the actual observed efficacy of our competitors’ Tax-Loss Harvesting services.
Using additional backtests, we can also see that our Tax-Loss Harvesting strategy has a significant advantage over an approach that only checks for losses once per year. To create the comparison, we run backtests which only allow loss-harvesting at year-end. Figure 3 shows the harvesting efficiency ratio, averaged across each 10-year subperiod, for Wealthfront’s Tax-Loss Harvesting strategy and the year-end harvesting strategy. For any particular risk score, we can compare the Harvesting Efficiency of our strategy to that of the year-end strategy by taking the ratio of the two Harvesting Efficiency values. On average, across the ten risk scores, this ratio is 128%.
Tax-Loss Harvesting may be a highly valuable way to improve the tax efficiency of your portfolio, but it’s important to understand that it is a tactical approach and should not interfere with your strategic investment objectives such as broad diversification through an optimal asset allocation, disciplined and tax-efficient rebalancing and low-cost indexing.
Since Tax-Loss Harvesting systematically lowers the cost basis of a portfolio by replacing securities (ETFs or stocks) that trade at a loss, investors might be concerned with how to deal with a portfolio with a low cost basis in the future. Generally speaking, portfolios with a low cost basis require more careful disposition. Investors may choose to minimize their tax liabilities that result fromTax-Loss Harvesting by using the low basis portfolio as a charitable donation or passing the portfolio on to heirs through an estate at a stepped-up cost basis.
Tax-Loss Harvesting is only relevant for taxable accounts. It does not apply to tax-deferred accounts such as IRAs and 401(k) accounts, since gains and losses in those accounts are not taxable events. However alternative ETFs may need to be used when investing your tax deferred account to avoid wash sales. Tax-Loss Harvesting is also not typically suited for custodial accounts such as UTMA/UGMA accounts unless the minor has significant taxable capital gains or income from other sources.
We believe the results presented in this white paper clearly demonstrate that Wealthfront’s fully automated Tax-Loss Harvesting service could significantly improve the after-tax returns for young people with a long investment time horizon, and pay for itself. Our research shows that for the vast majority of clients, the benefits of Tax-Loss Harvesting significantly outweigh Wealthfront’s advisory fee. We thus believe Tax-Loss Harvesting should be a fundamental component of most every individual’s investment management strategy.
Tables 4a and 4b below display the 2021 income tax brackets for married couples filing jointly, along with the prevailing federal tax rates for ordinary income, dividends, interest, short-term capital gains, and long-term capital gains. Ordinary income rates have two components – a base rate and an additional Medicare tax of 1.45% for joint incomes of $250,000 or less or 2.35% for incomes above $250,000. Taxpayers with joint incomes above $250,000 also pay an additional 3.8% Net Investment Income Tax on all capital gains, dividends, and interest.
In addition to the above federal tax rates, income and capital gains are subject to taxation at the state level. State tax rates vary considerably, from no income tax to rates of over 12% for those in the highest brackets in California. As such, your income and short-term capital gains can be subject to taxation ranging from roughly 10% (lowest federal tax bracket + no state tax) to over 50% (highest federal tax bracket + highest California tax brackets). Long-term capital gains are subject to lower levels of taxation, varying from 0% to over 30%.

The results of the historical backtests are intended to be used to help explain possible benefits of the Tax-Loss Harvesting strategy and should not be relied upon for predicting future performance. Backtested results are calculated by the retroactive application of a model constructed on the basis of historical data and based on assumptions integral to the model which may or may not be testable and are subject to losses. Backtested results have inherent limitations. Specifically, backtested results do not reflect actual trading or the effect of material economic and market factors on the decision-making process. Actual performance may differ significantly from backtested performance. Clients should be aware that the potential for loss (or gain) may be greater than demonstrated in the backtests. The results are not predictions, but they should be viewed as reasonable estimates. Backtested results are adjusted to reflect the reinvestment of dividends and other income and, except where otherwise indicated, are presented net of fees.
Wealthfront assumed it would have been able to purchase the securities recommended by the model and the markets were sufficiently liquid to permit all trading. Different methodologies may have resulted in different outcomes. For example, WEalthfront assumed that an investor’s risk profile and target allocation would not have changed during the time period shown; however, actual investors may have experienced changes to their allocation plan in response to changing suitability profiles and investment objectives. Furthermore, material economic and market factors that might have occurred during the time period could have had an impact on decision-making. Investors evaluating this information should carefully consider the processes, data, and assumptions used by Wealthfront in creating its historical backtests.
When Wealthfront says it replaces investments with “similar” investments as part of the Tax-Loss Harvesting strategy, it is a reference to investments that are expected, but are not guaranteed, to perform similarly and that might lower an investor’s tax bill while maintaining a similar expected risk and return on the investor’s portfolio. Expected returns and risk characteristics are no guarantee of actual performance.
Correlation is a measure of statistical association, or dependence, between two random variables. The values presented here are based on a particular historical sample period, data frequency, and are specific to the assets/indices used in the analysis. Correlations may change over time, such that future values of correlation may significantly depart from those observed historically.

The return information uses or includes information compiled from third-party sources, including independent market quotations and index information. Wealthfront believes the third-party information comes from reliable sources, but Wealthfront does not guarantee the accuracy of the information and may receive incorrect information from third-party providers. Unless otherwise indicated, the information has been prepared by Wealthfront and has not been reviewed, compiled or audited by any independent third-party or public accountant. Wealthfront does not control the composition of the market indices or fund information used for its calculations, and a change in this information could affect the results shown.
Wealthfront’s investment strategies, including portfolio rebalancing and tax loss harvesting, can lead to high levels of trading. High levels of trading could result in (a) bid-ask spread expense; (b) trade executions that may occur at prices beyond the bid ask spread (if quantity demanded exceeds quantity available at the bid or ask); (c) trading that may adversely move prices, such that subsequent transactions occur at worse prices; (d) trading that may disqualify some dividends from qualified dividend treatment; (e) unfulfilled orders or portfolio drift, in the event that markets are disorderly or trading halts altogether; and (f) unforeseen trading errors. The performance of the new securities purchased through the Tax-Loss Harvesting service may be better or worse than the performance of the securities that are sold for Tax-Loss Harvesting purposes.
Tax loss harvesting may generate a higher number of trades due to attempts to capture losses. There is a chance that Wealthfront trading attributed to tax loss harvesting may create capital gains and wash sales and could be subject to higher transaction costs and market impacts. In addition, tax loss harvesting strategies may produce losses, which may not be offset by sufficient gains in the account and may be limited to a $3,000 deduction against income. The utilization of losses harvested through the strategy will depend upon the recognition of capital gains in the same or a future tax period, and in addition may be subject to limitations under applicable tax laws, e.g., if there are insufficient realized gains in the tax period, the use of harvested losses may be limited to a $3,000 deduction against income and distributions. Losses harvested through the strategy that are not utilized in the tax period when recognized (e.g., because of insufficient capital gains and/or significant capital loss carryforwards), generally may be carried forward to offset future capital gains, if any.
Wealthfront only monitors for Tax-Loss Harvesting for accounts within Wealthfront. The client is responsible for monitoring their and their spouse’s accounts outside of Wealthfront to ensure that transactions in the same security or a substantially similar security do not create a “wash sale.” A wash sale is the sale at a loss and purchase of the same security or substantially similar security within 30 days of each other. If a wash sale transaction occurs, the IRS may disallow or defer the loss for current tax reporting purposes. More specifically, the wash sale period for any sale at a loss consists of 61 calendar days: the day of the sale, the 30 days before the sale, and the 30 days after the sale. The wash sale rule postpones losses on a sale, if replacement shares are bought around the same time. Wealthfront may lack visibility to certain wash sales, should they occur as a result of external or unlinked accounts, and therefore Wealthfront may not be able to provide notice of such wash sale in advance of the Client’s receipt of the IRS Form 1099.
The effectiveness of the Tax-Loss Harvesting strategy to reduce the tax liability of the client will depend on the client’s entire tax and investment profile, including purchases and dispositions in a client’s (or client’s spouse’s) accounts outside of Wealthfront and type of investments (e.g., taxable or nontaxable) or holding period (e.g., short- term or long-term). Except as set forth above, Wealthfront will monitor only a client’s (or client’s spouse’s) Wealthfront accounts to determine if there are unrealized losses for purposes of determining whether to harvest such losses. Transactions outside of Wealthfront accounts may affect whether a loss is successfully harvested and, if so, whether that loss is usable by the client in the most efficient manner.
A client may also request that Wealthfront monitor the client’s spouse’s accounts or their IRA accounts at Wealthfront to avoid the wash sale disallowance rule. A client may request spousal monitoring online or by calling Wealthfront at (844) 995-8437. If Wealthfront is monitoring multiple accounts to avoid the wash sale disallowance rule, the first taxable account to trade a security will block the other account(s) from trading in that same security for 30 days.
