The rule in Washington

Washington levies no income tax but charges an excise on large long-term gains: 7% above a $278,000 standard deduction, rising to 9.9% on gain beyond $1,000,000.

  • Washington levies no income tax but does tax long-term capital gain by excise: 7% on the first $1,000,000 above the standard deduction, and 9.9% above that, from tax year 2025 (ESSB 5813).
  • The standard deduction is $278,000 for 2025 and is adjusted annually; the 2026 amount had not been published when this was compiled, so 2026 uses the 2025 figure.
  • Real estate is exempt, as are assets in retirement accounts, most business assets that can be depreciated or expensed, timber, and commercial fishing privileges. Short-term gain is not taxed at all.

This covers a straightforward sale of stock, funds, crypto or property. It does not model the $250,000/$500,000 exclusion on a main home, depreciation recapture on a rental (taxed at up to 25%), collectibles (28%), qualified small business stock, wash sales, or a 1031 exchange.
Your other income was reduced by the 2026 standard deduction of $16,100 to reach taxable income. Switch to "taxable income" under More options if you have already done that.

Assumptions
  • One sale of a straightforward capital asset — shares, funds, crypto or investment property — by an individual US resident.
  • The gain is stacked on your other taxable income, which is what decides the federal band.
  • No main-home exclusion, depreciation recapture, collectibles rate, qualified small business stock, opportunity zone or 1031 exchange.
  • State tax uses that state's rule for a gain allocated to it; a gain sourced to another state, or a part-year move, is not modelled.
  • No local income tax: county in Maryland and Indiana, municipal in Ohio and Pennsylvania, city in New York.

Frequently asked questions

Does Washington tax capital gains?

Washington levies no income tax but charges an excise on large long-term gains: 7% above a $278,000 standard deduction, rising to 9.9% on gain beyond $1,000,000.

How much is capital gains tax in Washington?

On a $100,000 long-term gain for someone earning $100,000, Washington takes $0 — an effective 0%. Federal tax adds $15,000, for $15,000 in all.

Is short-term capital gain taxed differently in Washington?

Yes — Washington's excise applies to long-term gains only. A short-term gain is not taxed by the state at all, though it is federally, at ordinary rates.

How long do I have to hold something for the lower rate?

More than one year, federally. The holding period starts the day after you acquire the asset, so something bought on 10 March is long-term only if sold on 11 March the following year or later. Inside a year the gain is ordinary income at your income tax bracket, which for most people is 22% or 24% rather than 15%.

Do I pay Washington tax on a gain if I moved away before selling?

Generally you are taxed by the state you were resident in when the gain was realised, and some states also tax gains sourced to property inside them however long you have been gone. A part-year move usually means allocating the gain between the two states. This page assumes a full-year Washington resident.
