2026 long-term capital gains rates

Filing status0% up to15% up to20% above
Single$49,450$545,500$545,500
Married filing jointly$98,900$613,700$613,700

Thresholds apply to total taxable income, with the gain “stacked” on top of ordinary income. Example: single, $40,000 ordinary taxable income, $50,000 gain. The first $9,450 of the gain fills the 0% band up to $49,450, and the remaining $40,550 is taxed at 15% = $6,082.

Short-term gains

Assets held one year or less are taxed at ordinary rates. The calculator adds the gain to your other taxable income and takes the difference in tax.

Net investment income tax

An extra 3.8% applies to the smaller of net investment income or modified AGI above $200,000 (single), $250,000 (joint) or $125,000 (separate). These thresholds are not indexed for inflation. If you leave MAGI blank, the calculator estimates it as taxable income plus the gain plus the standard deduction.

Not modeled

Collectibles (28% max), unrecaptured Section 1250 gain on real estate (25% max), the home-sale exclusion ($250,000 / $500,000), loss carryovers and state tax.

Federal estimates using 2026 IRS figures and the standard deduction. They leave out credits, state tax and other deductions, so treat them as a planning number, not a tax return.
