Tax-Loss Harvesting

Tax-loss harvesting is an investment strategy that involves selling securities at a loss to generate capital losses that can offset capital gains realized elsewhere in your portfolio. If your capital losses exceed your capital gains in a given year, you may deduct up to $3,000 of the excess loss against ordinary income ($1,500 if married filing separately). Any remaining losses can be carried forward to future tax years indefinitely.

The key to effective tax-loss harvesting is maintaining your desired investment exposure. After selling an investment at a loss, you typically purchase a different but similar investment to keep your portfolio allocation intact. For example, you might sell one broad market index fund at a loss and purchase a different broad market index fund from another provider. The goal is to capture the tax benefit without meaningfully changing your investment strategy.

An important rule to understand is the wash sale rule, which prevents you from claiming a loss if you purchase a "substantially identical" security within 30 days before or after the sale. This means you must wait at least 31 days to repurchase the same security, or you can immediately purchase a similar but not identical alternative. The wash sale rule also applies across accounts, including IRAs.

Tax-loss harvesting tends to be most valuable for investors in higher tax brackets, those with significant realized capital gains, and those with taxable investment accounts. It is less relevant for tax-advantaged accounts like IRAs and 401(k)s, where gains and losses do not trigger current tax consequences. Some financial advisors and robo-advisors offer automated tax-loss harvesting as part of their portfolio management services.

While tax-loss harvesting can provide meaningful tax savings, it is important to consider the full picture, including transaction costs, the impact on your portfolio's cost basis going forward, and whether the deferred tax liability will ultimately be paid at the same or a different rate.
