Calculate your 2026 capital gains tax. Enter sale price, cost basis & income to see short vs long-term rate, NIIT, and what you owe.
Your capital gains tax rate in 2026 depends on one thing above all else: how long you held the asset before selling. Sell an investment you owned for one year or less and your profit is a short-term capital gain, taxed at your ordinary income rate (10% to 37%). Hold it for more than one year and it becomes a long-term capital gain, taxed at a preferential rate of 0%, 15%, or 20% depending on your taxable income.
That single distinction can cut your tax bill by more than half. A taxpayer in the 32% federal bracket pays 32% on a short-term gain but only 15% on the identical gain held for 366 days. On a $20,000 profit, that timing difference is worth $3,400 in real money.

Long-term rates are tied to your total taxable income, not a separate schedule. Here are the inflation-adjusted 2026 thresholds:
Notice how generous the 0% band is. A married couple with $90,000 of taxable income can realize long-term gains that keep them under the ~$98,900 ceiling and pay zero federal tax on those gains. This is the foundation of "tax-gain harvesting," covered below.
Short-term gains get no break — they stack on top of your wages and are taxed at the 2026 federal ordinary brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. For reference, the 2026 standard deduction is $15,000 (single) and $30,000 (married filing jointly), which reduces the taxable income figure those rates apply to.
Example: You earn $85,000 in wages (single filer, 22% marginal bracket) and flip a stock for a $10,000 profit after holding it five months. That $10,000 is taxed at 22%, costing you $2,200. Had you held it 13 months instead, it would fall in the 15% long-term band — a $1,500 bill and a $700 saving for waiting eight more months.
High earners face a surcharge on top of the rates above. The Net Investment Income Tax adds 3.8% to capital gains (and dividends, interest, and rental income) once your modified adjusted gross income exceeds:
These thresholds are not indexed for inflation, so more taxpayers cross them every year. A single filer with a $300,000 long-term gain in the 20% bracket effectively pays 23.8% federally once NIIT applies.
Assume a single filer with $120,000 of other taxable income who sells a stock position for a $50,000 gain. Here's how the holding period changes the outcome:
| Scenario | Holding Period | Rate Applied | Tax on $50,000 |
|---|---|---|---|
| Short-term | 11 months | 24% ordinary | $12,000 |
| Long-term | 13 months | 15% LTCG | $7,500 |
Bottom line: Holding two extra months saves this investor $4,500 — a 9% return on the position generated purely by patience. The median investor who reviews holding periods before selling captures most of this swing.
The formula is straightforward:
Capital Gain = Sale Price − Cost Basis
Your cost basis is what you paid for the asset, including commissions and reinvested dividends. Three details trip people up:
Gains on collectibles (art, coins, precious metals) are capped at a 28% rate, not 20%. Depreciation recapture on real estate (unrecaptured Section 1250 gain) is taxed up to 25%.
If you sell your primary residence, you can exclude up to $250,000 of gain ($500,000 married filing jointly) provided you owned and lived in it for at least two of the last five years. This is one of the most valuable tax breaks available to ordinary households.
Losses net against gains dollar-for-dollar. If your losses exceed your gains, you can deduct up to $3,000 against ordinary income per year and carry the rest forward indefinitely.
Sell underperforming positions to bank losses that offset your gains. Watch the wash-sale rule: if you buy a "substantially identical" security within 30 days before or after the sale, the loss is disallowed.
If a gap year, early retirement, or a sabbatical drops your taxable income into the 0% long-term bracket, deliberately realize gains tax-free and reset your cost basis higher. This is especially powerful before required minimum distributions begin — see our RMD Calculator 2026 to model when distributions push your income up.
Gains inside a Roth IRA or 401(k) aren't taxed as capital gains at all. For taxable accounts, simply crossing the one-year line converts ordinary rates into preferential ones. Coordinating this with your overall income — including Social Security and wages — matters; our Social Security Tax Calculator 2026 and Take-Home Paycheck Calculator 2026 help you see where your taxable income will land before you sell.
Don't forget your state. Most states tax capital gains as ordinary income with no preferential rate. California taxes gains up to 13.3%, and Washington imposes a 7% tax on long-term gains above roughly $270,000. Nine states — including Florida, Texas, and Nevada — levy no state income tax, so capital gains there face only the federal rate.
Short-term gains apply to assets held one year or less and are taxed at ordinary income rates of 10%–37%. Long-term gains apply to assets held more than one year and are taxed at preferential rates of 0%, 15%, or 20%. The one-year-and-one-day threshold is the single biggest factor in your rate.
In 2026, single filers with taxable income up to about $49,450 and married couples filing jointly up to about $98,900 pay 0% on long-term capital gains. The gain itself counts toward that income limit, so only the portion that keeps you under the threshold qualifies for the 0% rate.
You owe NIIT if your modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly). It adds 3.8% on top of your capital gains rate, so a top-bracket investor can pay an effective 23.8% federally. These thresholds are not adjusted for inflation.
Yes. Losses offset gains dollar-for-dollar. If losses exceed gains, you can deduct up to $3,000 against ordinary income each year and carry forward any remainder indefinitely. Beware the wash-sale rule, which disallows the loss if you rebuy a substantially identical security within 30 days.
Add all reinvested dividends to your original purchase price to get your true cost basis, then subtract that basis from the sale price. Reinvested dividends were already taxed as income, so failing to include them in your basis means paying tax twice on the same money.
