You lock in a paper loss and make it real. That real loss can offset real gains elsewhere. For example, you sell Stock A at a $5,000 loss. You also sell Stock B at a $5,000 gain. The loss cancels the
gain. You owe $0 in capital gains tax on that sale. The key term here is capital loss — a loss you realize when you sell an asset for less than you paid. Unrealized losses do not count. You must sell to claim the tax benefit. This move does not fix a bad investment. It simply makes the loss work for you. You still need a sound long term plan. Short Term vs Long Term Gains and Losses The IRS treats short term and long term gains in different ways. Short term means you held the asset for one year or less. Long term means you held it for more than one year. Short term gains face ordinary income tax rates. Those rates range from 10% to 37% in 2026 under finalized IRS federal brackets. Long term gains face lower rates of 0%, 15%, or 20% for most investors in
2026, with thresholds adjusted for inflation including the updated standard deduction. The key term is netting process — the IRS rule that requires you to match short term losses against short term gains first. You then match long term losses against long term gains. This order affects your total savings. Short term losses are more valuable. They offset high taxed short term gains first. Smart investors harvest short term losses when they can. Who Can Benefit Most From This Strategy Tax-loss harvesting helps taxable brokerage accounts only. It does not help IRAs or 401(k) plans. Those accounts already grow tax deferred or tax free. High earners gain the most. According to Fidelity, investors in higher brackets saved the most in a 2024 analysis. A top earner can save up to 37% on short term offsets plus state tax savings. The key term is taxable account — a regular brokerage account
with no special tax shelter. Gains and losses here trigger taxes each year. If you hold stocks, ETFs, mutual funds, or crypto in such an account, this strategy can help you. Even middle income earners can benefit. Anyone who pays capital gains tax can use this tool. It works best when you have gains to offset.
