How to figure your long-term capital gains bracket

To find your long-term capital gains rate: (1) work out your taxable income including the gain; (2) compare it to your filing status's breakpoints. A single filer in 2026 pays 0% while total taxable income stays under $49,450, 15% up to $545,500, and 20% above. The gain stacks on top of ordinary income, so part of one gain can fall in two bands. General information, not tax advice.

Step by step

  1. Find your ordinary taxable income (wages and other income minus your deduction), before the gain.
  2. Add the long-term gain on top to get total taxable income.
  3. Locate the breakpoints for your filing status (see the bracket table).
  4. Apply the rate band by band. The slice of the gain that fits below the 15% ceiling is taxed at 15%; any slice above it is taxed at 20%. If your total is under the 0% ceiling, that slice is 0%.
  5. Check the NIIT. If your modified AGI tops $200,000 (single) / $250,000 (joint), add 3.8% on the over-threshold portion.

Worked example

A single filer has $40,000 of ordinary taxable income and a $30,000 long-term gain. Total taxable income is $70,000. The 0% band for 2026 ends at $49,450, so the first $9,450 of the gain is taxed at 0% and the rest at 15%. No NIIT applies because income is far below the threshold. Use the calculator to run your own figures.

Frequently asked questions

How do I know if my capital gains are taxed at 0%, 15% or 20%?

Add your gain to your other taxable income. If the total is below your filing status's 0% ceiling ($49,450 single / $98,900 joint for 2026), the long-term gain is taxed at 0%. Between that and the 15% ceiling, it is 15%. Above the upper threshold, 20%. A large gain can straddle two bands.

Does my gain push my ordinary income into a higher bracket?

No - long-term capital gains are taxed in their own 0/15/20% schedule and do not raise the rate on your ordinary income. But the gain does count toward the taxable income that decides which capital-gains band the gain itself falls into, and it can affect other thresholds like the NIIT.

What income figure do I use - gross or taxable?

Taxable income: your income after the standard or itemized deduction. The 0/15/20% breakpoints are stated in taxable-income terms, so subtract your deduction first.
