    How Washington capital gains tax works

    Washington has no general state income tax, so most capital gains are not taxed at the state level.

    Washington taxes long-term capital gains over roughly $270,000 at 7%; ordinary income is untaxed.

    You will still owe federal capital gains tax — this calculator estimates the state portion only.

    Federal tax still applies

    The IRS taxes long-term gains (assets held over a year) at 0%, 15% or 20% depending on income, and short-term gains as ordinary income.

    So even in a no-income-tax state, selling an investment at a profit usually creates a federal tax bill.
