Arizona Capital Gains Tax Rate (2026)
Arizona capital gains tax overview
Arizona adopted a flat 2.5% income tax rate effective 2023, replacing its prior graduated system.
Federal + Arizona combined rates
Your total capital gains tax bill includes both layers — federal and state. Here is what an Arizona investor pays in 2026 for long-term gains:
| Federal Long-Term Rate | Arizona State Rate | Combined Rate | Plus NIIT (if applicable) |
|---|---|---|---|
| 0% | 2.50% | 2.50% | 6.3% |
| 15% | 2.50% | 17.5% | 21.3% |
| 20% | 2.50% | 22.5% | 26.3% |
The NIIT (Net Investment Income Tax) adds an extra 3.8% for taxpayers whose MAGI exceeds $200,000 (single) or $250,000 (married filing jointly). It is a federal tax only — Arizona does not have an equivalent.
How Arizona compares to other states
Arizona's top rate of 2.50% places it in the lower-middle tier of state capital gains taxation. For comparison:
- Zero-tax states (FL, TX, NV, etc.): 0% — total with 15% federal = 15%
- Low-rate states (AZ, IN, PA): 2.5–3.1% — total with 15% federal = 17.5–18.1%
- Arizona: 2.50% — total with 15% federal = 17.5%
- High-rate states (NY, NJ): 10.75–10.9% — total with 15% federal = ~26%
- California: 13.3% — total with 15% federal = 28.3%
Tax-reduction strategies for Arizona residents
With a top state rate of 2.50%, minimizing capital gains tax is particularly important in Arizona. Key strategies:
- Hold over 1 year for long-term federal rates (0/15/20%). Arizona does not offer a preferential state rate, but federal savings alone are often 7–17%.
- Tax-loss harvesting: Offset your gains with losses realized in the same year. A $20,000 loss offsets $20,000 of gains dollar-for-dollar, saving up to 23% ($4,500) on that $20,000 at top rates.
- 0% bracket planning: In lower-income years (retirement, sabbatical, between jobs), realize gains at the federal 0% rate. You still owe Arizona state tax, but eliminating the federal component is significant.
- Donate appreciated stock directly to charity or a donor-advised fund to avoid capital gains tax entirely while generating a charitable deduction for the full fair market value.
- Installment sales: If selling a business or real estate, structuring as an installment sale spreads the gain over multiple years, potentially keeping each year's gain in a lower bracket.
Detailed Arizona capital gains tax rules
Tax history and legal basis
Arizona taxes capital gains as ordinary income. In 2023, Arizona moved to a flat tax rate of 2.5%, down from a progressive system with rates up to 4.5%.
Exemptions and special treatment
Arizona allows a 25% exclusion on long-term capital gains from Arizona-sourced assets (like AZ real estate or AZ business sales). This reduces the effective rate to ~1.875% on qualifying gains. The exclusion does not apply to stock market gains.
Filing requirements
File Form 140 (resident). Capital gains flow through from your federal return. Arizona conforms to the federal definition of capital gains. Filing deadline is April 15.
Recent changes and legislative updates
Arizona's 2023 flat tax of 2.5% made it one of the lowest-tax states in the nation. The previous top rate was 4.5%. Combined with the 25% exclusion on AZ-sourced gains, the state is increasingly attractive for retirees and investors relocating from high-tax states like California.
Worked example: $50,000 capital gain in Arizona
Here's exactly what an Arizona resident would owe on a $50,000 long-term capital gain with $80,000 in other income (single filer, 2026):
| Component | Amount | Notes |
|---|---|---|
| Capital gain | $50,000 | Long-term (held over 1 year) |
| Federal tax (15%) | −$7,500 | Based on $80,000 ordinary income + gain |
| Arizona state tax (2.5%) | −$1,250 | Applied to the full gain amount |
| Total tax owed | −$8,750 | Federal + state combined |
| You keep | $41,250 | 82.5% of your gain |
After both federal and Arizona state tax, you keep $41,250 of your original $50,000 gain. The effective combined rate is 17.5%. This is well below the national average, making Arizona one of the more tax-friendly states for investors.
Frequently asked questions — Arizona
Does Arizona tax short-term and long-term gains differently?
No — Arizona taxes both short-term and long-term capital gains as ordinary income at the same rates as wages. There is no state-level preferential rate for patience. The federal system, however, taxes long-term gains at 0/15/20% vs. up to 37% for short-term — a significant difference that applies regardless of state.
Do I need to file an Arizona tax return if I only have capital gains?
If you have capital gains income and meet Arizona's filing threshold, you are required to file an Arizona state income tax return. The threshold is typically similar to the standard deduction amount — check the AZ Department of Revenue for the current year's filing requirements.
What if I moved to Arizona mid-year?
If you moved to Arizona during the year, you are a part-year resident. Arizona generally taxes capital gains realized while you were an Arizona resident. Gains realized before you moved may be taxable by your prior state. Keep detailed records of when each sale occurred relative to your move date.
