Not tax advice. This article explains how stepped-up basis works and how Arizona's tax rules apply to inherited property — for educational purposes only. Your situation may differ. Consult a CPA or licensed tax professional before making decisions based on any information here.
TL;DR — The Short Answer
- Stepped-up basis resets your cost basis to the home's fair market value on the date of death — so selling shortly after inheriting typically produces little or no capital gain.
- Arizona has no state inheritance tax and no state estate tax — abolished in 2005. Zero state-level exposure regardless of estate size.
- Federal capital gains tax only hits appreciation above the stepped-up value — if the home is worth $450,000 when you inherit it and you sell for $465,000, you have a $15,000 gain, not a gain on the original purchase price.
- Inherited property automatically qualifies for long-term capital gains rates — 0%, 15%, or 20% depending on your income, even if you sell within days of inheriting.
- Federal estate tax applies only to very large estates — the exemption is $15 million per person starting 2026 (signed into law July 4, 2025). Most Arizona families are not close to this threshold.
What Stepped-Up Basis Means for an Inherited Arizona Home
When you inherit a home, the IRS resets your cost basis to the property's fair market value on the date the previous owner died. This is called stepped-up basis. Under IRS Publication 551 (Basis of Assets, Rev. December 2025), it means any capital gains the original owner accumulated over their lifetime are permanently erased — you start fresh at today's value, not what they paid decades ago.
The practical result: if you sell the home soon after inheriting it, and the market hasn't moved much since the date of death, your taxable capital gain is close to zero. The "stepped-up" part refers to the fact that this new basis is almost always higher than what the decedent originally paid — hence the step up.
The One Exception Worth Knowing
Stepped-up basis does not apply if you or your spouse gave the property to the decedent within one year before their death and then inherited it back. In that narrow scenario, your basis is the decedent's original adjusted basis, not the date-of-death value. For the vast majority of inherited family homes in Arizona, this exception doesn't apply.
Arizona Has No State Inheritance Tax or Estate Tax
Arizona abolished its state estate tax in 2005 and has never imposed a state inheritance tax. When you inherit a home in Arizona — whether in Scottsdale, Phoenix, Mesa, or anywhere else in the state — you owe the state of Arizona nothing based on the inheritance itself. No state forms, no state estate return, no state percentage. This makes Arizona one of the most favorable states in the country for inheriting real property.
Federal estate tax is a separate matter, but it only applies to very large estates. The One Big Beautiful Bill Act, signed into law on July 4, 2025, permanently set the federal estate and gift tax exemption at $15 million per person (indexed for inflation starting 2027). For married couples, that is $30 million combined. The exemption applies to the gross estate — the total value of everything the decedent owned. A single-family home in the Phoenix metro area, even a high-end Scottsdale property, rarely pushes an estate anywhere near $15 million on its own.

Worked Example: The Numbers in Practice
Here is an illustrative example — the numbers are not real transactions but are representative of a typical Phoenix-area inherited home scenario.
Without stepped-up basis, the heir would face a $388,000 capital gain — a potentially six-figure tax bill. With stepped-up basis, the taxable gain is $13,000, and at the 15% long-term capital gains rate, the federal tax owed is roughly $1,950. The rate depends on income — heirs below certain income thresholds may pay 0%.
Basis and Capital Gains Scenarios: A Data Table
The following scenarios illustrate how stepped-up basis changes the tax picture depending on when you sell and how much the home appreciates after you inherit it. All figures are illustrative.
| Scenario | Stepped-Up Basis | Sale Price | Taxable Gain | Est. Tax (15% rate) |
|---|---|---|---|---|
| Sell within 60 days, flat market | $420,000 | $418,000 | $0 (loss) | $0 |
| Sell within 6 months, slight appreciation | $420,000 | $435,000 | $15,000 | ~$2,250 |
| Sell after 2 years, strong appreciation | $420,000 | $490,000 | $70,000 | ~$10,500 |
| Sell after 5 years, major appreciation | $420,000 | $580,000 | $160,000 | ~$24,000 |
| Without stepped-up basis (hypothetical, for comparison only) | $95,000 (original cost) | $435,000 | $340,000 | ~$51,000 |
Tax estimates use a 15% long-term capital gains rate. Your actual rate may be 0%, 15%, or 20% depending on your total taxable income. Consult a CPA for your specific situation.
How the Basis Is Established — and Why Getting This Right Matters
The stepped-up basis is the fair market value of the property on the date of death — not the date you filed probate, not the date the deed transferred to you, and not today's value. This usually means getting a date-of-death appraisal from a licensed real estate appraiser. If the estate was required to file a federal estate tax return (Form 706), the executor will have filed Schedule A (Form 8971) and you should receive a copy that documents the estate tax value — that becomes your basis.
For smaller estates that don't file Form 706, a qualified appraisal done close to the date of death is the standard way to establish the number. Keep this appraisal permanently — it is the foundation of your tax position when you eventually sell.
Caution: Some heirs assume Zillow's "Zestimate" or the county assessor's value is their stepped-up basis. Neither is a qualified appraisal. If you're audited, IRS expects a licensed appraiser's opinion of fair market value as of the date of death. A rough number today used backward is not the same thing. Get the appraisal done while the death-date evidence is fresh.
Selling an Inherited Arizona Home: Cash Sale vs. MLS Listing
Stepped-up basis applies the same way regardless of how you sell. Whether you list on the MLS through an agent or sell directly to a cash buyer, the taxable gain is identical — it is the sale price minus the stepped-up basis. What changes is the net proceeds after transaction costs.
A cash sale typically means no agent commission (usually 5–6% on a traditional listing), no repair requests, and a closing timeline measured in days rather than 60–90 days. For inherited homes that may have deferred maintenance, be mid-probate, or involve out-of-state heirs who need to settle the estate quickly, those factors often matter more than squeezing out the last dollar on sale price. That said, the right choice depends on the home's condition, the local market, and your specific timeline — not a rule of thumb.

Frequently Asked Questions About Capital Gains on Inherited Arizona Homes
Do you pay capital gains tax when you sell an inherited house in Arizona?
Usually little to nothing. When you inherit a home, your tax basis resets to the property's fair market value on the date of the owner's death — this is called stepped-up basis. If you sell at or near that value, your capital gain is zero or very small. Arizona has no state inheritance tax or estate tax. Any federal capital gains tax applies only to appreciation above the stepped-up value. Consult a CPA or tax professional for advice specific to your situation.
What is stepped-up basis for an inherited home?
Stepped-up basis means your cost basis in an inherited property is reset to the fair market value at the date of the previous owner's death — not what they originally paid for it. If the home was bought for $80,000 in 1985 and was worth $450,000 when the owner died, your basis is $450,000. A sale at $460,000 produces only a $10,000 gain, not a $380,000 gain. This treatment is established under IRS Publication 551 (Basis of Assets). Consult a CPA for situation-specific guidance.
Does Arizona have an inheritance tax or estate tax?
No. Arizona abolished its state estate tax in 2005 and has never had a state inheritance tax. Arizona heirs owe no state-level estate or inheritance tax regardless of the estate's size. Federal estate tax may apply to very large estates — the exemption is $15 million per person starting in 2026 under the One Big Beautiful Bill Act signed July 4, 2025. Most Arizona families are well below this threshold.
How long do I have to sell an inherited home in Arizona to avoid capital gains tax?
There is no strict deadline tied to tax treatment. Inherited property automatically qualifies for long-term capital gains rates regardless of how long you hold it before selling — even if you sell within weeks of inheriting it. The key variable is not timing; it is how much the property has appreciated above the stepped-up basis. If you sell quickly while the market is close to the date-of-death value, your gain is typically minimal. Consult a CPA or tax advisor for advice specific to your estate.
Can I sell an inherited Arizona home to a cash buyer and still benefit from stepped-up basis?
Yes. Stepped-up basis applies regardless of how you sell — cash buyer, MLS listing, or any other method. What matters is the sale price relative to your stepped-up basis, not the type of buyer. A cash sale can close in days rather than months, which is often valuable when an estate needs to settle quickly, probate is ongoing, or siblings want to divide proceeds. Consult a CPA about your specific tax situation before closing.
