Selling a rental property in Tucson can mean a big tax bill, especially if you’ve owned it for years and it has gained value. A 1031 exchange can let you defer that tax by rolling your sale proceeds into another investment property. The rules are strict, though, and the timing is unforgiving. Chris J. Reynolds, CPA, helps Tucson and Southern Arizona investors plan these exchanges before the For Sale sign goes up, so the numbers work and the deadlines don’t catch you off guard.
What Is a 1031 Exchange?
Under Section 1031 of the Internal Revenue Code, you generally don’t owe tax right away when you swap real property held for business or investment for other real property of a “like kind.” Instead of paying tax on the gain now, you carry it forward into the new property. The tax isn’t forgiven. It’s deferred, and it can keep deferring through future exchanges.
Since 2018, this applies only to real property, and not to your primary home or property held mainly to resell, such as a flip.
Key 1031 Exchange Rules to Know
- 45-day identification deadline. After you close on the property you’re selling, you have 45 days to identify your replacement property in writing.
- 180-day closing deadline. You must receive the replacement property within 180 days of the sale, or by the due date of your tax return for that year (including extensions), whichever comes first. Both clocks start at the same time, and neither one can be extended.
- Like-kind real property. “Like kind” is broader than most people expect. A rental house can be exchanged for an apartment building, a retail center or vacant land, as long as both are held for investment or business use in the United States.
- Qualified intermediary (QI). In a typical delayed exchange, you can’t touch the sale proceeds. A QI holds the money and handles the paperwork. Your agent, attorney, or accountant from the past two years generally can’t serve as your QI, so we help you coordinate with an independent professional.
- Boot. Any cash or non-like-kind property you receive in the exchange is called boot, and it’s taxable up to the amount of your gain.
- Debt replacement. If you pay off less debt than you take on, or vice versa, the difference can create taxable boot. To avoid it, you generally need to buy property of equal or greater value and replace the debt, or add cash of your own to make up the difference.
How Chris Helps Before, During and After Your Exchange
Most exchange problems start before the sale. Here’s where we come in:
- Planning before you list. We estimate your gain and tax cost, then help you decide whether an exchange makes sense at all. Sometimes paying the tax and moving on is the better call.
- Coordinating the team. We work with your qualified intermediary, title company and realtors so the contracts, closing documents and timing all line up.
- Calculating deferred gain and basis. We figure out how much gain you’re deferring and what your basis is in the new property, which drives your future depreciation.
- Form 8824 reporting. The exchange is reported on your tax return using IRS Form 8824, and we prepare it so the transaction is documented properly.
Chris is also a landlord with rental properties in Tucson. He’s been on the owner’s side of repairs, tenants and tough sell-or-hold decisions, so he understands what you’re weighing.
Arizona Treatment of 1031 Exchanges
Arizona starts its income tax calculation from your federal numbers, so gain that you properly defer under Section 1031 is generally deferred for Arizona income tax as well. If an exchange fails or you receive boot, the taxable gain is generally taxed in Arizona too. Arizona’s individual income tax is a flat rate (2.5% for the 2025 tax year), and Arizona allows a 25% subtraction for qualifying net long-term capital gains from assets acquired after 2011. If you live outside Arizona but own property here, you may still have an Arizona filing obligation. We look at both the federal and Arizona sides together.
Common 1031 Exchange Mistakes
- Waiting to plan until you’re under contract. A QI generally has to be in place before you close on the sale.
- Touching the money. If sale proceeds land in your account, even briefly, the exchange can fail.
- Missing a deadline. Day 45 and day 180 are firm. Weekends and holidays don’t extend them.
- Forgetting the tax-return date. If you sell late in the year, your 180 days can be cut short unless you file an extension.
- Ignoring debt. Buying a cheaper property or taking on less debt can trigger boot.
- Exchanging property that doesn’t qualify. A flip, a primary residence or foreign property won’t work.
1031 Exchange FAQ
Can I do a 1031 exchange on my Tucson rental house?
Usually, yes, if you’ve held it for investment or business use and you’re buying other qualifying real property in the U.S.
Do I have to use all of my sale proceeds?
To defer all of the gain, you generally need to reinvest all of the net proceeds and replace the debt. Any cash you keep is boot and may be taxable.
Can I exchange into property in another state?
Yes. Real property in the U.S. is generally like kind to other U.S. real property, so Tucson investors often exchange into properties elsewhere. State tax rules vary, so we look at that too.
What if I can’t find a replacement property in 45 days?
The deadline can’t be extended. If you miss it, the exchange generally fails and the gain is taxable for the year of the sale.
