If you’re thinking of selling your Arizona home in 2025, you may be wondering: “Will I have to pay taxes on my profit?”
Many homeowners believe the sale of a primary residence is always tax-free. The truth is, it depends.
The IRS allows you to exclude up to $250,000 in gains if you’re single or $500,000 if you’re married filing jointly — but only if you meet the rules under IRS Section 121.
The Basics of the Exclusion
- You must have lived in the home for 2 of the last 5 years.
- Couples must be married and file taxes jointly to qualify for the $500K exclusion.
- You can only use this exclusion once every 2 years.
What Counts Toward Your Cost Basis?
Not everything you spend on your home counts.
- Capital Improvements (increase basis): kitchen remodels, new roof, solar, HVAC, or even tree removal if roots threaten the foundation.
- Routine Maintenance (doesn’t increase basis): trimming trees, painting, or fixing a leaky faucet.
Tip: Always keep receipts for improvements. Your CPA will thank you when it’s time to calculate your gain.
Arizona’s Unique Advantage
Arizona is a community property state, which gives surviving spouses an important benefit. When one spouse passes away, the surviving spouse receives a 100% step-up in cost basis for the entire home.
👉 Example: A couple bought their Chandler home for $200,000. At the husband’s passing, the home was worth $800,000. The wife’s new basis became $800,000 — so if she sold right away, she’d owe no tax at all.
⚠️ But here’s the catch: to secure that stepped-up basis, you need a professional appraisal at the time of death. Without it, your CPA may have no way to defend your numbers.
Common Mistakes to Avoid
- Assuming all sales are tax-free.
- Forgetting the 2-year residency rule.
- Adding kids to the title (creates tax headaches instead of avoiding them).
- Skipping the appraisal after a spouse passes.
- Not keeping receipts for improvements.
Pro advice:
“The IRS doesn’t care about what your neighbor said — they care about your paperwork.”
