How to Avoid Capital Gains Taxes on a Home Sale in Arizona
With home values having appreciated dramatically over the past decade, many sellers are sitting on significant gains. Here's what you actually need to know — and what your options are.

First: most primary residence sellers won't owe anything
The federal government provides a significant exclusion for homeowners selling their primary residence — up to $250,000 in gains for single filers and $500,000 for married couples filing jointly. To qualify, you must have owned the home and lived in it as your primary residence for at least two of the five years before selling.
What this means in practice: if you're a married couple who bought your Scottsdale home for $600,000 and are selling for $1,050,000 — a $450,000 gain — you owe zero federal capital gains tax, as long as you meet the requirements. Most homeowners in this market fall comfortably within these limits.

When it becomes a tax issue
For high-end Scottsdale and Arcadia homes owned for a long time, gains can exceed the federal exclusion. Federal long-term capital gains rates for 2026: 0% for married couples with income up to $98,900; 15% for most middle and upper-middle income filers; 20% for the highest earners. There's also a 3.8% Net Investment Income Tax that can apply for higher-income sellers on gains above the exclusion.
On the Arizona state side: Arizona taxes capital gains as ordinary income at the flat 2.5% rate, but as of January 1, 2026, Arizona expanded its 25% long-term capital gains subtraction to all long-term gains — making the effective state rate just 1.875%. Additionally, the Arizona Senate passed SB 1633 in early 2026, which would create an unlimited state exemption on home sale gains. As of this writing, it still needs to clear the House and governor's signature.
Key strategies to reduce your liability
Track your cost basis. Every improvement you've made — renovations, additions, pool installation — increases your cost basis and reduces your taxable gain. Keep records of every significant improvement.
Time your sale. If you're in a lower-income year (retirement, career transition), selling then may put you in a lower capital gains bracket.
1031 exchange for investment properties. If selling an investment property rather than a primary residence, a 1031 exchange defers gains by rolling proceeds into a like-kind property.
