Arizona capital gains tax overview

Arizona capital gains tax planning starts with the federal rules, then layers on Arizona's own treatment (graduated income tax (top rate up to 2.5%)). This calculator estimates both so you can see a combined effective rate before you sell stocks, crypto, real estate, or other capital assets.

Federally, short-term gains (held one year or less) are taxed as ordinary income, while long-term gains generally use 0%, 15%, or 20% preferential rates for tax years 2025 and 2026. High earners may also owe the 3.8% Net Investment Income Tax when MAGI exceeds the IRS threshold for their filing status.

Arizona generally taxes capital gains under its graduated income-tax framework. For planning estimates we apply Arizona's top modeled rate (graduated income tax (top rate up to 2.5%)) to taxable gains. Your actual marginal state rate may be lower depending on total Arizona taxable income.

Arizona figures in this model are drawn from the official source we cite for the state: https://azdor.gov/. Confirm the current-year statute or agency page before you file — rates and special rules can change.

Arizona’s model uses graduated income tax with a top rate up to 2.5% on taxable capital gain. Among states that tax the gain, that top rate is one of the lower ones encoded here.

The 2.5% figure is a planning ceiling in this tool, not a flat tax on the first dollar. Federal NIIT is still added when MAGI is high enough, and it does not shrink because Arizona’s rate is low.

FAQ

Arizona FAQs

How does Arizona tax capital gains?

Arizona generally taxes capital gains under its graduated income-tax framework (Graduated income tax (top rate up to 2.5%)). For planning we apply the top modeled rate to taxable gains; your actual Arizona marginal rate may be lower depending on total taxable income.

Is the Arizona amount on this calculator exact?

No. Graduated states are estimated at the top modeled rate, not a full multi-bracket state return. Federal tax and NIIT are stacked separately. Federal short-term and long-term capital gains tax, and the 3.8% Net Investment Income Tax when MAGI exceeds the IRS threshold, can still apply.

Where do Arizona rates come from?

Our model cites https://azdor.gov/. Use this page for a combined federal-plus-state planning estimate, then confirm with Arizona instructions or a CPA.

Are Arizona capital gains sourced by residency or by where the asset sits?

Arizona generally taxes residents on worldwide income, including capital gains, under its graduated framework (Graduated income tax (top rate up to 2.5%)). Nonresidents may still owe Arizona tax on certain sourced assets such as in-state real property. This page assumes Arizona residency for the state line.

Is Arizona’s capital-gains tax a flat 2.5%?

The model’s top rate is up to 2.5% on a graduated scale. It is not encoded as a flat tax on every dollar.

Does a low Arizona rate remove the 3.8% federal NIIT?

No. NIIT is federal. Arizona’s top rate, up to 2.5%, does not change the NIIT threshold.
