No state tax on gains · Only federal tax and NIIT apply (Washington taxes large long-term gains).
Flat-rate states · Gains are taxed as ordinary income at a single rate.
Graduated-rate states · Gains are taxed as ordinary income across brackets.
How the capital gains calculator works
Long-term gains (held more than a year) use the federal 0/15/20% rates, stacked on top of your other taxable income, so part of a gain can be taxed at 0% and the rest at 15% or 20%, not a flat rate. Short-term gains are taxed as ordinary income. The 3.8% Net Investment Income Tax applies once income clears the threshold. Most states then tax the gain as ordinary income; Texas and Florida tax it not at all, and Washington applies a stand-alone excise only to large long-term gains.
These are annual-bracket estimates, not your final tax liability. They exclude the alternative minimum tax, loss carryovers, local taxes, and credits. Where a 2026 figure has not yet been finalized, the calculator says so plainly. This is general information, not tax advice.
