Daperis CPA1031 Exchange Guide: How Real Estate Investors Defer Capital Gains
Sell an investment property you've held for years and the tax bill can be brutal. Federal capital gains tax, depreciation recapture, the extra tax on investment income, and whatever your state charges on top, it can eat a big chunk of your gain before you even reinvest a dollar.
A 1031 exchange lets you put that off. Not avoid it forever, just delay it, by rolling the money from one investment property into another "like-kind" property instead of cashing out. Done right, you owe nothing on that gain the year you sell. Done wrong, even off by a few days, the whole thing falls apart and you owe tax on the full gain like a normal sale.
What Actually Qualifies
Both the property you sell and the one you buy have to be for investment or business use, not your home, and not something you bought to flip. "Like-kind" is broader than people expect. Almost any investment real estate counts as like-kind to any other. A rental house for a commercial building, land for an apartment complex, one state for another, all fine. What doesn't count anymore is personal property. Since 2017, this only works for real estate, not equipment, vehicles, or other business property.
The Two Clocks That Run Everything
Two deadlines start the moment you close on your original property's sale, and they run at the same time, not one after the other.
You have 45 days to name, in writing, the property or properties you want to buy. It has to be specific, a real address or legal description, not "something in Brooklyn." It has to go to your intermediary, not just be written down somewhere for yourself, and it has to arrive before day 45 ends.
You then have 180 days total from the original sale, not 180 days after the 45 ends, the 180 includes those first 45, to actually close on the new property. If your tax return for that year is due, with extensions, before day 180, the deadline moves up to your filing date instead. People miss this when they put off filing an extension.
Neither deadline moves for holidays, weekends, financing problems, or almost anything else. The only real exception is a federally declared disaster. Miss either one and the whole exchange fails, you owe tax as if you just sold normally.
You Can't Touch the Money
This trips up more people than the deadlines do. The money from your sale can't pass through your hands, even for a second, or the exchange is dead. That's why you need a qualified intermediary, a neutral third party who holds the money and uses it to buy the new property for you. Set this up before you close on the sale, not after. Adding one after the fact is usually too late.
What Still Gets Taxed
To defer all your gain, the new property generally needs to be worth as much or more than what you sold, you need to reinvest all your equity, and your new debt needs to match or beat the old debt. Fall short anywhere and that shortfall, called "boot," gets taxed even though the rest of the exchange still works. You can do a partial exchange on purpose, you just pay tax on the boot and defer the rest.
The Tax Doesn't Disappear, It Follows You
A 1031 exchange delays the tax on depreciation you've already claimed, it doesn't erase it. Your old property's numbers carry over into the new one. That affects how much you can depreciate going forward, and it means the deferred tax is still waiting for you whenever you eventually sell without exchanging again.
Watch Out for Family Deals
If you're exchanging directly with a relative, both sides usually need to hold onto the property for at least two years, or the deferred gain gets taxed retroactively. There are a few exceptions, mainly if someone dies or there's an involuntary sale, but in general, exchanging with family or a business partner needs extra care. Flag it early if that's your situation.
Paperwork
A completed exchange goes on Form 8824 with your return for the year you sold, even though you don't owe tax on the deferred gain yet.
Why People Do This Over and Over
There's no limit on how many times you can exchange. Some investors chain these together for decades, moving into bigger properties, better markets, all without a tax bill along the way. Eventually the deferred gain catches up, either when a property finally sells outright, or, in some cases, never, if it passes to heirs, who get a fresh basis at that point.
Keep It Simple / Key Takeaway 🍕
A 1031 exchange is powerful, but it doesn't forgive mistakes. The deadlines are firm, the intermediary needs to be in place before you close, and the property ID has to be specific and on time. If you're thinking about selling an investment property and buying another, this needs to be part of the plan before you sign a listing, not after the sale closes.
Combining a 1031 exchange with cost segregation on the replacement property is a common next step, here's how that works.
