1031 Exchange Basics for Rental Property Owners

A Section 1031 exchange lets some investors sell one piece of real estate and roll the proceeds into another without paying tax on the gain right away. It is a deferral, not forgiveness, and the rules are strict. This guide covers the basic concepts so you know what to ask before you list a property. Tax law and IRS guidance can change, so confirm details with a qualified tax professional and the IRS before acting.

What a 1031 exchange is

Under Section 1031 of the tax code, you can defer gain when you exchange real property held for investment or business use for other real property of like kind. For most landlords, that means selling one rental and buying another rental or investment property. Since 2018, the rule applies only to real property, not to personal property such as appliances or furniture, as described in the IRS page on like-kind exchanges of real estate.

“Like-kind” for real estate is fairly broad. It refers to the nature of the property, not its quality or use. A rental house can generally be exchanged for a different type of investment real estate. Your own home, and property held mainly for resale (like a flip), generally do not qualify. U.S. real estate is not like-kind to real estate outside the United States. The exchange is reported on Form 8824.

Why landlords use it

When you sell a rental, you may owe tax on the gain, including on depreciation you claimed. Our guide to selling a rental property explains how that works. An exchange can postpone that bill and keep more money working in the next property. The tax basis of the old property generally carries over to the new one, so the deferred gain stays built in.

The core rules

• Qualified intermediary. In the usual deferred exchange, where you sell first and buy later, you cannot touch the sale proceeds. A qualified intermediary holds the funds and handles the paperwork; using one is the standard safe harbor described in the Form 8824 instructions. If sale proceeds land in your own account, the exchange can fail.
• Identification deadline. You must identify replacement property within 45 days after you transfer the property you are giving up. The identification must be in writing, signed, clearly describe the property, and be delivered to the right party within that window.
• Closing deadline. You must receive the replacement property within 180 days of the transfer, or by the due date (including extensions) of your tax return for that year, whichever is earlier. Both clocks run at the same time from the day you transfer the old property; they are calendar days, and weekends and holidays generally do not extend them. The IRS has postponed these deadlines in limited cases, such as for some federally declared disasters, so ask your advisor if one affects you.
• Same taxpayer. The taxpayer who sells generally must be the one who buys. Ownership questions, especially with LLCs and partnerships, need care. See landlord LLC and legal structure.
• Set it up first. You need to arrange the exchange before closing the sale, not afterward.

Confirm the exact deadlines and identification rules in current IRS guidance for your situation.

Where “boot” comes in

If you receive cash or other non-like-kind property in the exchange, or end up with less debt on the new property than you had on the old one, the difference is generally called boot and may be taxable. Planning the debt and equity on both sides helps avoid surprises.

A simple example

The numbers below are round and invented to show the idea. They are not a prediction of your taxes.

This simplified example ignores closing costs and assumes the replacement costs the same as the old property sold for, with no cash taken out and no drop in debt. If you add cash to buy a more expensive property, that added amount generally increases your basis. In the exchange column, you start the new property with a lower basis than its price, so there is less depreciation to deduct, and a larger gain later if the new property is sold in a taxable sale. Tax deferral is useful, but it is not free money.

Costs and trade-offs

• Intermediary fees and added closing costs
• Pressure from the deadlines, which can push you toward a property you would not otherwise buy
• A lower basis and smaller depreciation on the replacement
• Loss of flexibility if you wanted to cash out

Also consider the whole picture. Selling and paying tax may make sense if you want to simplify, reduce debt, or leave landlording. Look at rental cash flow and cap rate to judge whether the replacement property is actually a better investment, not just a tax move.

Other situations to ask about

Exchanges interact with other tax rules, such as how property passes to heirs, or how a rental converted to personal use is treated. These areas are complex and depend on current law, so raise them with your professional if they apply to you.

Next steps

Before you list, write down your adjusted basis, estimated sale price, and what you would want to buy next. Meet with a CPA to compare the tax from a regular sale against an exchange, and ask for a referral to a qualified intermediary. Then read the IRS page on like-kind exchanges and check the current deadlines. Keep clean records of improvements and depreciation, as described in rental property depreciation explained, since they drive your basis.
