Arizona Capital Gains Tax Rules
Arizona taxes capital gains at its flat 2.5% income tax rate in 2026. Long-term gains on assets acquired after December 31, 2011 get a 25% subtraction (A.R.S. 43-1022), so only 75% of the gain is taxed — an effective rate of 1.875%. Short-term gains, and long-term gains on assets acquired before 2012, are taxed in full. This state tax is separate from — and in addition to — the federal capital gains tax you owe to the IRS.
Understanding Arizona's capital gains rules is essential for investors, homeowners selling property, and business owners who plan to sell assets. The calculator above computes your estimated federal and Arizona state capital gains tax based on your sale price, cost basis, holding period, and income. It subtracts the 2026 federal standard deduction ($16,100 single, $32,200 married filing jointly, $24,150 head of household) from the income you enter, stacks the gain on top of your other income, and taxes each slice at its own rate.
Federal vs Arizona Capital Gains Tax
The federal tax on a gain depends on your taxable income and on how long you held the asset. For long-term gains (held more than 12 months), the 2026 federal rates set by IRS Rev. Proc. 2025-32 are 0% on taxable income up to $49,450 single / $98,900 married filing jointly / $66,200 head of household, 15% up to $545,500 single / $613,700 joint / $579,600 head of household, and 20% above those thresholds. The gain is stacked on top of your other income, so one sale can be taxed partly at 0%, partly at 15% and partly at 20%. Short-term gains are taxed as ordinary income at the 2026 federal brackets of 10% to 37%. A 3.8% Net Investment Income Tax is added on the lesser of the gain or the amount by which your modified adjusted gross income exceeds $200,000 (single or head of household) or $250,000 (married filing jointly).
Worked example (2026): a single filer with $90,000 of other income sells stock held for two years at a $50,000 gain. Federal tax is $7,500 (the whole gain falls in the 15% band) and Arizona tax is $938, a combined $8,438 or 16.9% of the gain. Sold after 11 months instead, the same gain is short-term: $11,364 federal plus $1,250 Arizona tax, $12,614 in total. The calculator above reproduces both results.
Arizona Cap Gains Strategies & Exemptions
Several strategies can help Arizona taxpayers reduce their capital gains tax burden. First, hold assets for more than 12 months to qualify for the lower long-term federal rate. Second, harvest capital losses to offset gains — if you have losing positions, selling them in the same tax year can reduce your net taxable gain. Third, use tax-advantaged accounts (401k, IRA, HSA) to shelter future investment growth from both federal and Arizona state tax.
For Arizona homeowners, the federal home-sale exclusion allows you to exclude up to $250,000 (single) or $500,000 (married filing jointly) of gain from the sale of a primary residence, provided you meet the 2-of-5-year ownership and use tests. The calculator does not apply this exclusion, so enter only the gain that remains after it. Consult an Arizona tax professional to understand which exclusions apply to your specific situation.
Always work with a qualified tax professional before executing large asset sales. Tax laws change, and individual circumstances — such as installment sales, like-kind exchanges (1031 exchanges for real estate), or business asset sales — can significantly affect your total tax liability.
Phoenix & Scottsdale Real Estate — Arizona 1031 Exchange Rules for Cap Gains Deferral
Arizona's investor real-estate markets — Phoenix, Scottsdale, Chandler, Gilbert, Tucson — see heavy 1031 exchange activity because a well-executed 1031 defers both the 15-20% federal LTCG and Arizona's 2.5% state tax indefinitely. Per the Arizona Department of Revenue guidance on capital gains, Arizona conforms to the federal §1031 rules with no state-level deviations, so an investor selling a Scottsdale rental and reinvesting proceeds into a Tucson multi-family within the standard 45-day identification / 180-day close window defers the full state + federal bill. Two Arizona-specific rules matter: (1) primary residences do NOT qualify for 1031 — those must use the federal §121 $250K/$500K exclusion instead; (2) short-term vacation rentals (Airbnb, VRBO) held less than 2 years are treated as inventory not investment property, which disqualifies them from §1031. Arizona's flat 2.5% rate, applied after the 25% long-term subtraction, makes even a "small" gain worth deferring — on a $500,000 long-term gain that is $9,375 of Arizona tax deferred ($12,500 if the property was acquired before 2012). Snowbird investors (retirees splitting between AZ and MN/WI) should also check the "safe harbor" residency rules — being an AZ resident on the sale date locks in the 2.5% rate regardless of where the property is located.

Frequently Asked Questions
What is the Arizona capital gains tax rate in 2026?
Arizona taxes capital gains at its flat 2.5% income tax rate in 2026. Long-term gains on assets acquired after December 31, 2011 get a 25% subtraction, so only 75% of the gain is taxed — an effective rate of 1.875%.
Does Arizona tax short-term vs long-term capital gains differently?
Yes, slightly. Both are taxed at Arizona's flat 2.5% rate, but a long-term gain on an asset acquired after 2011 gets a 25% subtraction, so only 75% of it is taxed. Short-term gains are taxed in full.
Are there Arizona capital gains exemptions?
Arizona subtracts 25% of a net long-term capital gain on assets acquired after December 31, 2011 (A.R.S. 43-1022). At the federal level you can exclude up to $250,000 of gain ($500,000 if married filing jointly) on the sale of your main home if you meet the ownership and use tests. Consult a tax professional for your specific situation.
How does Arizona capital gains compare to federal rates?
Federal long-term capital gains rates for 2026 are 0%, 15% and 20%: the 15% rate starts above $49,450 of taxable income for single filers ($98,900 married filing jointly) and the 20% rate above $545,500 ($613,700). Arizona state tax is charged in addition to the federal tax. For example, a single filer with $90,000 of other income and a $50,000 long-term gain owes $7,500 federal and $938 to Arizona.
Do I owe Arizona capital gains tax if I move before selling?
If you move before selling an asset, your state tax obligation depends on where you were a resident when the sale occurs. If you are a Arizona resident at the time of sale, Arizona capital gains rules apply. Always consult a tax advisor when changing states.
Can I use a 1031 exchange to defer Arizona capital gains tax on rental property?
Yes — Arizona conforms to federal §1031 with no state-specific deviations. Sell a Phoenix or Scottsdale rental, identify replacement investment property within 45 days, close within 180 days, and both the federal 15-20% LTCG and Arizona's 2.5% state tax are deferred until the replacement property is sold outside a 1031. On a $500,000 long-term gain that is $9,375 in Arizona tax deferred ($12,500 if the property was acquired before 2012). Two limits: (1) primary residences do NOT qualify — use the federal §121 exclusion instead ($250K single / $500K MFJ); (2) short-term rentals (Airbnb/VRBO) held less than 2 years may be treated as inventory rather than investment, disqualifying the exchange.
Do Arizona snowbirds who split time between AZ and another state pay the 2.5% state cap gains tax?
Only if they are an Arizona resident on the sale date. Arizona uses a facts-and-circumstances residency test — driver license state, voter registration state, days-present count (generally 9+ months in AZ = clear resident), and where the tax home is filed all matter. If you sell stock, real estate, or business interests while still legally domiciled in MN, WI, or another origin state, you owe that state's tax rate (which is often higher than 2.5%). Snowbirds planning a large sale year should consult a tax pro before switching residency mid-year — the timing of the residency change relative to the sale date determines which state's rate applies.
