Gifting a rental property: carryover basis and why heirs usually fare better

A landlord parent who wants to hand a rental to a grown child has two honest choices: deed it over now as a gift, or leave it in the will and let it pass at death. Most articles on this topic are written for large estates worried about estate tax, so they treat gifting as a smart way to move assets out of the estate. For a self-managing landlord with one to ten units, the estate-tax worry is usually irrelevant, and the real question is much narrower: which path leaves the family with the smaller income-tax bill when the property is eventually sold. The answer turns on two numbers, and gifting almost always loses.

The reason is basis. When you gift the property, the recipient takes your basis, your accumulated depreciation, and your built-in gain. When they inherit it, the basis resets to the value on the date of death and the depreciation slate is wiped clean. This guide walks the gift mechanics from IRS Publication 551 and Form 709, then runs the same duplex through both paths so you can see the gap in real dollars before you sign a deed.

Gift tax: the scary part that usually costs nothing

The phrase “gift tax” frightens people away from a move that, for a small landlord, rarely produces a tax bill at all. There are two separate thresholds, and confusing them is the most common mistake on the subject.

• The annual exclusion. You can give any one person up to 19,000 dollars in 2026 (38,000 dollars if you and a spouse split the gift) with no filing at all. A rental is worth far more than that, so a property gift will exceed the annual exclusion in the year you make it.
• The lifetime exemption. Exceeding the annual exclusion does not mean you owe tax. It means you file Form 709 to report the gift, and the excess reduces your lifetime exemption, which is 15 million dollars in 2026. You write a check to the IRS only after your cumulative lifetime gifts pass that figure.

So for a parent gifting a 340,000-dollar duplex, the practical gift-tax cost is one Form 709 and a 340,000-dollar dent in a 15 million-dollar exemption almost no small landlord will ever spend down. Gift tax is not the problem with gifting a rental. Income tax later is.

Carryover basis: what the recipient actually inherits

When you gift appreciated property, the recipient takes your basis, not its current value. That carryover basis drags three things along with it that decide the eventual tax bill.

• Your built-in gain. If you bought for 200,000 dollars and the duplex is worth 340,000 dollars, the recipient inherits your 140,000-dollar unrealized gain. When they sell, that gain is theirs to pay tax on.
• Your accumulated depreciation. Every year of depreciation you claimed lowered your basis. The recipient takes that lowered basis and the depreciation history with it, which sets up depreciation recapture taxed at up to 25 percent when they sell.
• Your remaining depreciation schedule. The recipient does not start a fresh 27.5-year clock. They continue your schedule, with whatever years are left, on the carried-over building basis. No reset, no new write-offs from a higher number.

Publication 551 also adds a wrinkle for property worth less than your basis at the time of the gift: a dual-basis rule, where the recipient uses your basis to figure a gain and the lower fair market value to figure a loss. For an appreciated rental this rarely bites, but if you are gifting a property that has fallen below your basis, flag it for your CPA, because the loss side can vanish entirely.

Inherit instead: the step-up that resets everything

Now run the other path. If the same duplex passes to your child at your death rather than as a lifetime gift, the basis steps up to fair market value on the date of death. Publication 559 describes the contrast plainly: the heir's basis is generally the date-of-death value, and the donor's accumulated depreciation does not carry over.

That step-up does three things a gift cannot:

• It erases the unrealized gain. The decades of appreciation you built up are wiped out. If the heir sells near the date-of-death value, there is little or no capital gain to tax.
• It clears the depreciation recapture. Because the depreciation history does not follow the property, the recapture that would have hit a gift recipient disappears.
• It starts a fresh schedule. The heir gets a new 27.5-year depreciation clock on the stepped-up basis, which is a larger number to write off than your old carried-over basis would have been.

The same duplex, both ways, in real numbers

Say you bought a duplex for 200,000 dollars, with 40,000 dollars allocated to land and 160,000 dollars to the building. Over the years you claimed 60,000 dollars of depreciation, so your adjusted basis is 140,000 dollars. The duplex is now worth 340,000 dollars, and your child will sell it shortly after receiving it. Here is the gap.

• Gift now. Your child takes your 140,000-dollar adjusted basis. Selling at 340,000 dollars produces a 200,000-dollar taxable gain, of which 60,000 dollars is depreciation recapture taxed at up to 25 percent and the remaining 140,000 dollars is long-term capital gain. Even at favorable rates, the family is looking at tens of thousands in tax on a property the parent could have passed differently.
• Inherit later. The basis steps up to 340,000 dollars at death. Selling at 340,000 dollars produces roughly zero gain, no recapture, and no tax. The 60,000 dollars of depreciation you claimed over the years is never recaptured.

The two numbers that drive that entire comparison are the unrealized gain (340,000 minus 140,000, or 200,000 dollars) and the accumulated depreciation (60,000 dollars). Gifting hands both to the recipient. Inheriting erases both. For a sister-case walkthrough of the receiving end, read inheriting a rental property and the step-up in basis, and fit either path into the broader rental property tax picture before you decide.

When gifting still makes sense

The step-up wins on income tax, but it is not the only consideration, and there are real cases where a lifetime gift is the right call. None of them are about saving the recipient money on a sale.

• You want the income off your return now. Shifting a rental to an adult child in a lower bracket moves the rental income and the depreciation to them. If they will hold the property rather than sell, the carryover-basis penalty never gets triggered.
• You are spending down a large estate. If you are one of the rare small landlords whose total estate approaches the exemption, moving appreciating property out now keeps future growth outside the estate. That is an estate-tax question, not an income-tax one.
• The property has not appreciated. If your basis and the market value are close, there is little built-in gain to hand over, so the step-up saves little and the gift is cleaner.

The decision is really a single comparison: how big is the unrealized gain and the accumulated depreciation you would be passing along, and is that cost worth whatever the gift accomplishes. The larger those two numbers, the more a gift costs the family relative to waiting.

Pin down the two numbers before you sign anything

Whichever way you lean, the gift-versus-bequest call is unanswerable until you know the property's current value, its adjusted basis, and how much depreciation you have claimed. Those are the inputs your CPA needs, and they are the inputs most landlords cannot produce on demand. I built rents.ai partly because I was tired of reconstructing basis and depreciation from a spreadsheet at the worst possible moment: its portfolio value and equity tracking surface the unrealized gain, and its depreciation rollup shows the accumulated depreciation you would be handing the recipient, the two numbers that decide gift versus bequest. What it cannot do is make the call, file Form 709, or replace a CPA: it organizes the figures, and a preparer who can see your whole return and estate has to weigh them.
