Taxes are one of the most anxiety-inducing parts of selling property as an out-of-state owner. Will you get double-taxed? What’s this withholding you’ve heard about? Does the stepped-up basis really eliminate your capital gains?

The good news is that the tax picture is usually better than people expect — especially for inherited property. Understanding what you may owe (and what you may not owe) helps you make better decisions and plan your timeline. Here’s a plain-English breakdown of the key tax considerations.

Do You Owe Federal Capital Gains Tax?

When you sell property for more than your tax basis (generally what you paid for it, or its fair market value when you inherited it), the profit is considered a capital gain and may be subject to federal income tax.

The rate you pay depends on how long you held the property:

  • Long-term capital gains (held more than one year): taxed at preferential rates of 0%, 15%, or 20% depending on your total taxable income
  • Short-term capital gains (held one year or less): taxed at your ordinary income tax rate, which could be as high as 37%

Here’s where it gets much better for inherited property: thanks to the stepped-up basis (more on this below), your tax basis on inherited property is typically the fair market value at the date of death — not the original purchase price. This often dramatically reduces or even eliminates your capital gains.

Example: If you inherit a home worth $400,000 at the time of death and sell it for $420,000, you only owe capital gains on the $20,000 difference — not the full appreciation over the deceased’s lifetime. This is one of the most misunderstood and most valuable tax benefits of inherited property.

Note: A CPA can help you calculate your specific basis and estimated tax liability before you sell, so you can plan accordingly. We always recommend getting this number before you make decisions about timing or pricing.

Arizona State Income Tax on Real Estate Sales

Arizona levies state income tax on gains from real estate sales, including sales by nonresidents. If you live in another state and sell Arizona property, you’ll need to file an Arizona nonresident income tax return (Form 140NR) reporting the gain.

The natural question is: will you get taxed twice — once by Arizona and once by your home state?

Generally, no. Here’s why:

  • Arizona and California have a reciprocal credit arrangement. If you’re a California resident, you’ll report the gain on your California return, but California will give you a credit for the tax you paid to Arizona on the same income. (Arizona provides a similar credit going the other direction.)
  • Most other states have similar credit provisions. You’ll file in both states, but the credit mechanism ensures you’re not taxed twice on the same gain. Your home state taxes the gain and gives you credit for what you paid to Arizona, or vice versa.
  • States with no income tax (like Texas, Florida, Nevada, or Washington): you’ll pay Arizona tax on the gain, but there’s no home-state return to worry about on this income.

The specifics depend on your state and your overall income picture, which is why a CPA who understands multi-state filing is valuable here.

Arizona Nonresident Withholding

This is the one that surprises most out-of-state sellers.

Arizona requires buyers (or more commonly, the escrow or title company handling the closing) to withhold 3.5% of the gross sales price when the seller is a nonresident and the expected gain exceeds $1,000.

Let’s break down what that means with a concrete example:

  • You sell your Arizona property for $350,000
  • The title company withholds $12,250 (3.5% of $350,000)
  • This $12,250 is sent to the Arizona Department of Revenue on your behalf
  • You receive your remaining proceeds at closing

This is not an additional tax. It’s a prepayment — think of it like federal income tax withholding from your paycheck. When you file your Arizona nonresident return, you’ll calculate your actual Arizona tax liability on the gain and reconcile it against the amount withheld.

If the withholding exceeds your actual tax liability (which it often does, especially for inherited properties with a high stepped-up basis), you’ll receive a refund from the Arizona Department of Revenue for the difference.

There are limited circumstances where the withholding can be reduced or waived — for example, if the transaction will result in a loss rather than a gain. Your CPA can advise on whether to file for a withholding waiver before closing.

What Is the Stepped-Up Basis? (And Why It Matters for Inherited Property)

The stepped-up basis, explained simply: When you inherit property, your tax basis is “stepped up” to the fair market value at the date of death — not the original purchase price. This can significantly reduce or eliminate capital gains taxes when you sell.

Example: Your parents bought their Arizona home for $80,000 in 1985. It was worth $350,000 when they passed away. You sell it for $360,000. Your taxable gain is $10,000 (sale price minus stepped-up basis) — not $280,000 (sale price minus original purchase price). At a 15% long-term capital gains rate, that’s roughly $1,500 in federal tax instead of $42,000.

The stepped-up basis is one of the most significant tax provisions in the entire U.S. tax code for inherited property, and it’s frequently misunderstood. Many heirs assume they’ll owe tens of thousands in capital gains, only to discover that the stepped-up basis reduces their liability to a fraction of what they feared — or eliminates it entirely.

A few key points about the stepped-up basis:

  • It applies to all inherited property — not just property held in a trust. Whether you inherited through a will, a trust, or intestate succession, the stepped-up basis applies.
  • The “date of death” value is what matters. You’ll typically need an appraisal or Comparative Market Analysis (CMA) reflecting the property’s fair market value as of the date of death to establish your basis.
  • Community property states get a double step-up. Arizona is a community property state. If one spouse dies, both halves of the community property get a stepped-up basis — not just the deceased’s half. This can be a significant benefit for surviving spouses.
  • Inherited property is treated as long-term regardless of how long you’ve held it, so you’ll always qualify for the lower long-term capital gains rates.

Getting the stepped-up basis right is the single most important tax step for anyone selling inherited property. An incorrect basis calculation can mean paying thousands more in tax than you actually owe.

The 1031 Exchange: Deferring Gains If You're Reinvesting

If you’re selling an Arizona investment property (rental property, for example) and plan to purchase another investment property, a 1031 exchange (named after Section 1031 of the Internal Revenue Code) allows you to defer capital gains tax by reinvesting the proceeds into a “like-kind” property.

The key requirements:

  • The property being sold and the replacement property must both be held for investment or business use (not personal residences)
  • You must use a qualified intermediary — you cannot touch the sale proceeds yourself
  • You must identify replacement properties within 45 days of closing
  • You must close on the replacement property within 180 days

A 1031 exchange doesn’t eliminate the tax — it defers it to a future sale. But for investors who plan to continue holding real estate, it can be a powerful tool for building wealth without triggering a tax event.

Important: A 1031 exchange must be set up before you close on the sale. If you think this might apply to your situation, talk to a CPA or qualified intermediary well before your closing date. Once the sale closes without a 1031 structure in place, the opportunity is lost.

How the Sale Timeline Affects Your Taxes

When you sell can affect how much you owe. Here are the key timing considerations:

  • Long-term vs. short-term rates: Property held for more than one year qualifies for long-term capital gains rates (0%, 15%, or 20%). Property held for one year or less is taxed at your ordinary income rate (up to 37%). However, inherited property is always treated as long-term, regardless of how long you personally held it.
  • Tax year planning: If you’re expecting a large gain, timing the sale to fall in a year when your other income is lower can keep you in a lower capital gains bracket.
  • Arizona withholding timing: The 3.5% withholding happens at closing, and you won’t get any overpayment back until you file your Arizona nonresident return. If cash flow is a concern, factor this into your planning.
  • Stepped-up basis documentation: The longer you wait to sell after inheriting, the harder it can be to document the date-of-death value. Getting an appraisal or CMA soon after inheriting protects your basis and your tax position.

Working with a CPA Who Knows Arizona Nonresident Rules

Selling Arizona property as an out-of-state owner involves multi-state tax filing, potential withholding reconciliation, and (for inherited property) basis calculations that can make or break your tax outcome. This is not the year to use a generic tax prep service or file your own returns.

Look for a CPA who:

  • Has experience with Arizona nonresident returns (Form 140NR)
  • Understands multi-state credit calculations for your home state
  • Knows how to properly calculate and document a stepped-up basis for inherited property
  • Can advise on the 3.5% withholding and whether a waiver or reduction makes sense

The cost of working with a knowledgeable CPA is typically a few hundred dollars — and it can easily save you thousands by ensuring your basis is calculated correctly and your returns are filed properly.

Frequently Asked Questions

Do I have to pay taxes in Arizona if I live in another state?

If you sell property located in Arizona, you are subject to Arizona income tax on the gain from that sale, regardless of where you live. You’ll file an Arizona nonresident return (Form 140NR). However, your home state will generally give you a credit for taxes paid to Arizona, so you typically won’t be double-taxed on the same income.

What is the 3.5% Arizona withholding on real estate sales?

Arizona requires escrow or title companies to withhold 3.5% of the gross sales price when the seller is a nonresident and the expected gain exceeds $1,000. This is not an additional tax — it’s a prepayment of your Arizona income tax that you reconcile when you file your Arizona nonresident return. If more was withheld than you owe, you’ll receive a refund.

Do I owe capital gains tax if I inherited the property?

You may owe very little or nothing. When you inherit property, your tax basis is “stepped up” to the fair market value at the date of death. You only pay capital gains on the difference between the stepped-up basis and the sale price. If you sell relatively soon after inheriting, that difference is often minimal. Inherited property is also always treated as long-term, qualifying for lower tax rates.

Can I defer capital gains by doing a 1031 exchange?

If the property was used as an investment (rental, etc.) and you plan to purchase another investment property, a 1031 exchange can defer your capital gains tax. You must use a qualified intermediary, identify replacement properties within 45 days, and close within 180 days. The exchange must be set up before your sale closes. Consult a CPA or tax attorney to determine if this applies to your situation.
