When an investment goes down in value and you sell it or exchange it for a different investment, you realize a capital loss. There will be times where you may want to realize a capital loss on purpose for tax reasons to reduce your income tax bill. Capital losses can be used to offset capital gains, and potentially used to offset some ordinary income.

Key Takeaways

  • Realizing capital losses might be useful because they can offset capital gains.
  • You can deduct up to $3,000 per year of your losses that exceed your capital gains.
  • If your capital losses exceed the $3,000 limit, you can carry your losses forward to future tax years.
  • When selling stocks to tally capital losses, you cannot purchase the same stock again for 30 days before or after the sale.

Why You Would Intentionally Realize a Capital Loss?

One reason you might consider intentionally realizing capital losses would be if you were incurring large capital gains in the same tax year. Let's say you sold a piece of real estate, a business, or a mutual fund or stock with a large capital gain. You might be able to rearrange other investment holdings you have for the purpose of generating losses to offset your capital gain.

This works best with mutual funds and exchange-traded funds. With mutual funds, by exchanging one fund for another, you can realize a capital loss for tax reasons without necessarily incurring a long-term investment loss. Here’s an example of how this works:

  • Assume you own a Vanguard S&P 500 index fund. You bought it for $100,000 at the beginning of the year. The market went down, and it is now worth $70,000. You know in the long run the markets will recover, so you don’t want to sell it at a loss, but you would like to be able to use the loss for tax purposes.
  • Instead of selling your fund and going to cash or moving into a different type of investment, you sell it and buy a fund with a similar risk profile that tracks a different index. As the market recovers, you hope that your portfolio will recover.
  • Since you switched to a different investment, that $30,000 loss will be considered a realized loss and you will report it on your tax return.
  • If your capital losses exceed your capital gains for the year, you can deduct up to $3,000 of the loss against ordinary income. In many cases, you can then carry over into the next tax year any of those losses above $3,000.

Ordinary income tax rates are higher than capital gains tax rates. For someone in the 33% tax bracket, having an additional $3,000 of capital loss that could be deducted against ordinary income would save them an extra $390 a year (calculated by taking the difference between the 33% income tax rate and the 20% capital gains tax rate and multiplying by $3,000). For some taxpayers, it can save even more. When this strategy is used consistently it can add up to multiple thousands in tax savings over an investor's lifetime.

Capital Losses With Individual Stocks

With individual stocks, this strategy does not work in the same way. Although you can sell your existing stock, and realize the loss, you cannot easily replace it with a similar stock that would be expected to perform in the same way. You might come close by purchasing stock in the same industry, but company-specific factors may lead one stock to perform quite differently than the other.

When selling investments to realize a capital loss for tax purposes, make sure you are buying investments with different ticker symbols. If you buy the same security 30 days before or after the sale, the wash-sale rule may apply and your tax loss could be disallowed.


The wash sale rule does not apply if you sell and buy mutual funds with different ticker symbols, even if the two funds own the same underlying securities.

There are a variety of facts and circumstances (the fund's holdings, the proportion of securities, how the fund is managed, and who the manager is) you should consider when deciding if two funds are similar enough to trigger a wash sale. No clear rule has been set for mutual fund wash sales, so cautious investors may want to avoid selling a fund and then buying a fund that tracks the same index.

Frequently Asked Questions (FAQs)

What is a wash sale?

Per IRS rules, a wash sale is when, within 30 days before or after, you sell a security and then buy a substantially similar one. In general, wash sales would be used to offest capital gains with capital losses.

What are capital losses?

In investing, a capital loss occurs when you sell a security for a price that's lower than you bought it. For example, if you bought one share of Apple at $175 and then sold it at $150, you'd have a capital loss of $25.
