How are capital gains taxed in Wyoming in 2025?

Wyoming has no state individual income tax, so capital gains are not taxed at the state level. On top of that, the federal government taxes long-term gains at 0%, 15%, or 20% (and short-term gains at ordinary rates), and high earners may owe the 3.8% Net Investment Income Tax.

Does the 3.8% Net Investment Income Tax apply?

It can. The NIIT adds 3.8% on the lesser of your net investment income and the amount your modified AGI exceeds $200,000 (single or head of household), $250,000 (married filing jointly), or $125,000 (married filing separately). These thresholds are set by statute and are not adjusted for inflation. This calculator includes it automatically.

Wyoming Capital Gains Tax 2025

This calculator works out the total tax on a capital gain in Wyoming for the 2025 tax year — the federal 0% / 15% / 20% long-term rate, the 3.8% Net Investment Income Tax for high earners, and the Wyoming state portion. Wyoming has no state income tax, so the only tax on your gain is federal (plus NIIT for high earners).

Federal long-term gains (assets held over one year) are taxed at 0%, 15%, or 20% by total taxable income. For 2025 the 0% band runs to $48,350 (single) or $96,700 (married filing jointly), 15% up to $533,400 (single) or $600,050 (joint), and 20% above. Short-term gains are taxed at ordinary federal rates. High earners also owe the 3.8% Net Investment Income Tax (NIIT) on the lesser of the gain and modified AGI over $200,000 (single) / $250,000 (joint) / $125,000 (married filing separately).
