(UNITED STATES) — The Internal Revenue Service kept the federal tax rates on long-term capital gains at 0%, 15%, and 20% for tax year 2025, leaving retirees and other investors focused on how much income they can keep inside the 0% bracket.

IRS materials do not show a change to the rates themselves for 2025. The opening for tax savings comes from income levels, not from a new rate cut.

That distinction matters for households selling appreciated investments. Federal tax on gains still depends on taxable income and filing status, and retirees often report lower taxable income than workers, allowing more realized gains to fall into the 0% bracket.

For tax year 2025, the IRS thresholds for 0% long-term capital gains are $48,350 or less for single filers, $96,700 or less for married couples filing jointly, $64,750 or less for heads of household, and $48,350 or less for married people filing separately.

Above those levels, the IRS applies the 15% rate up to the next bracket, then 20% above that. Net short-term capital gains do not qualify for those rates and are taxed as ordinary income.

The structure leaves a narrow but valuable planning range for retirees. A person who no longer draws wages may have more room to realize gains at a federal tax rate of 0%, particularly if the standard deduction and modest ordinary income keep taxable income below the relevant threshold.

Capital gains tax also turns on timing. Gains are taxed when they are realized, meaning when the investment is sold, not while the asset simply rises in value on paper.

That makes the sale decision central. An investor can hold an appreciated stock, mutual fund, or other asset for years without triggering capital gains tax, then face the tax only in the year of sale.

The retiree angle in the IRS framework comes from that combination of lower ongoing income and control over realization. Someone who has left the workforce may be able to choose when to sell and how much gain to recognize in a given year, rather than stacking those gains on top of a full salary.

A single filer offers the clearest example. If taxable income totals $48,350, long-term capital gains fall inside the 0% bracket. If that filer instead has taxable income of $40,000, there is room for another $8,350 of long-term gains before crossing the threshold.

The tax effect can change quickly once income moves above it. Using that same single filer, a sale that pushes taxable income to $50,000 would place $1,650 above the $48,350 ceiling, with that slice moving into the 15% range under the IRS framework.

For a married couple filing jointly, the room is wider. Taxable income of $90,000 would leave $6,700 before reaching the $96,700 line for the 0% rate on long-term gains.

Heads of household face a threshold of $64,750. Married people filing separately use the same $48,350 figure as single filers.

Those thresholds apply only to long-term gains, which generally means gains on assets held long enough to qualify for long-term treatment. The IRS framework draws a hard line between those gains and short-term gains, which it taxes as ordinary income.

That difference can sharply alter the tax bill from one sale to the next. Two investors can realize the same dollar gain in the same year and still face different federal treatment if one gain counts as long term and the other counts as short term.

Most taxpayers who rise above the 0% thresholds remain in the 15% band before reaching the top capital gains rate of 20%. There is no adjustment to those three rates for 2025.

High-income taxpayers may owe more than the standard capital gains rate. The current guidance also points to the 3.8% net investment income tax, which can apply on top of capital gains tax.

That extra levy means the headline capital gains rate does not always capture the full federal bill. Investors with higher income can face the listed capital gains rate plus the additional 3.8% tax.

State taxes can also affect the final result, although the figures at issue here are federal IRS thresholds. Households looking at a large sale still need to measure the federal capital gains rate against any tax imposed where they live.

Retirees often look at these rules because their taxable income can fluctuate more than that of workers. Pension income, withdrawals, Social Security benefits, and investment sales do not always arrive in the same pattern each year, creating some flexibility in when gains are recognized.

That flexibility can produce wide swings in tax owed. A retiree who spreads sales over more than one tax year may keep more gains inside the 0% bracket, while a retiree who sells a large position in one year can push a larger share into the 15% range or higher.

The standard deduction adds to that dynamic by reducing taxable income before the capital gains thresholds are applied. Combined with lower ordinary income, that can leave more room under the IRS ceiling for a tax-free realization of long-term gains at the federal level.

Still, the opportunity is not automatic. A household must look at taxable income, filing status, the size of the gain, whether the gain is long term or short term, and whether the 3.8% net investment income tax applies.

The current IRS framework leaves the rates untouched while putting the focus on income management. The numbers that matter most in that exercise are the $48,350, $96,700, and $64,750 thresholds tied to filing status, along with the distinction between realized long-term gains and ordinary income.

Policy discussions around capital gains can shift, but the materials for 2025 do not show a change in the federal rate schedule. For now, the tax code continues to reward taxpayers who can keep taxable income low enough to use the 0% bracket, and retirees remain among the households most likely to benefit from that opening.
