What Happens to an STR's Tax Basis When You Die?

Basis is the number your exit is measured from

Every other page in this domain comes back to the same number: your adjusted basis. When you dispose of a short-term rental, your gain is measured using the amount realized and your adjusted basis. Adjusted basis is not simply the price you paid. It is what you paid, plus capital improvements, minus all the depreciation you claimed along the way. (The adjusted-basis guide covers basis in depth; the tax-bill guide works out the amount realized from sale consideration, debt payoff, and selling costs.) Depreciation is powerful because it lowers your taxable income now, but it does so by lowering your basis, which raises the gain waiting at the exit. That's the core tension across Wealth & Exit: the tax you defer through depreciation and through tools like the 1031 exchange doesn't disappear. It carries forward inside a lower and lower basis.

This page is about when deferred gain can stop being owed altogether, rather than being deferred again. That can happen when the property passes to an heir. It isn't something you can arrange with a transaction: it happens only at the owner's death.

What §1014 does at death

Under Internal Revenue Code §1014, when a person dies holding an appreciated asset, the basis of that asset is generally reset — "stepped up" — to its fair-market value on the date of death, in the hands of the person who inherits it. Put plainly, the heir is generally treated as if they acquired the property at its current value, not at the decedent's old, depreciation-reduced basis.

The consequence for a short-term rental is significant. Here is the careful version, because the details matter:

At death, §1014 generally resets the inherited property's basis to its date-of-death fair market value. Appreciation and depreciation-related built-in gain that would have mattered in a lifetime sale may therefore no longer produce the same income-tax gain to the heir. That can include potential unrecaptured §1250 gain associated with prior building depreciation and, depending on the assets and facts, built-in gain associated with depreciated §1245 components.

In other words, built-in gain is the gain a lifetime sale would have brought into tax: the appreciation, plus the specific depreciation-related pieces that the recapture and tax-bill guides break down by character. For the heir, that gain is measured against a fresh, higher basis. This is where gain carried during the owner's lifetime can cease to be built-in gain in the heir's hands. The recapture and tax-bill guides cover exactly how a lifetime sale would have taxed those pieces. The point here is plainer: the reset changes the basis the heir starts from.

It's a consequence of holding — not a strategy you run

This is the part generic articles get wrong, and it's the reason this page exists. A step-up is not something you do. You cannot execute it the way you execute a 1031 exchange or a cost-segregation study. It is simply what happens under current law if you are still holding the property when you die. That single fact reshapes everything people say about it:

It benefits your heirs, not you. During your lifetime you never touch that built-in gain tax-free. The only way to access the property's value without selling is to borrow against it. That is a refinance, which is not itself a taxable event; the Financing domain covers it. The step-up arrives only after you're gone, for someone else.

It can eliminate the inherited built-in income-tax gain, but it does not answer the estate-tax question. Those are two different sets of rules. Whether an estate owes estate tax is a completely separate question with its own rules, its own thresholds, and its own advisors. This page does not address estate tax, states no exemption figures, and is not estate-planning advice. If your estate is large enough for that question to matter, that's a conversation for your estate attorney and tax professional, not a website.

And because it depends on dying while holding, it can't be "used" as a plan without accepting what the plan requires: keeping that capital, and its deferred tax, locked in the asset for the rest of your life. That's a real trade-off. It connects directly to the question of whether a property still deserves your capital. A step-up can be one legitimate reason a long hold makes sense, but it is not a cost-free option.

Income-tax basis versus estate tax

Because the two get blurred constantly, it's worth being explicit. The step-up under §1014 is about income-tax basis — the number that determines capital gain and the depreciation-related pieces if the property is later sold. Estate tax is a separate federal tax on transfers at death, with its own rules, thresholds, and planning considerations. This page is only about the first. It deliberately states no estate-tax numbers, because those figures change and because deciding how they apply to you is exactly the kind of question that belongs with a qualified estate-planning professional. Keep the two ideas separate: a step-up can wipe income-tax built-in gain for your heirs while having nothing to say about whether your estate owes estate tax.

The traps that shrink or forfeit the step-up

The step-up is generous, which is precisely why so many well-intentioned moves accidentally give it away. These are the ones that bite short-term-rental owners specifically. For each one, the advice is the same: know the trap, then take it to a professional. Whether any of them applies to you turns on facts this page can't see.

Giving the property away during life. If you transfer an appreciated rental to your children (or anyone) as a gift while you're alive, §1015 generally gives them your carryover basis — your old, depreciation-reduced number — not a stepped-up one. The built-in gain carries over to them intact. The instinct to "just put the kids on the deed now" is a classic self-inflicted mistake: it can replace a potential future §1014 basis reset with carryover basis under §1015. A gift and a bequest (leaving the property to someone at death) have very different tax outcomes, and which one you want is an estate-planning decision for your attorney and tax pro.

How you own the property can decide whether you even get a clean step-up. The ownership structure matters enormously, and this is where the sharpest STR traps are:

• Held directly, or in a single-member LLC that's disregarded for tax, the step-up generally applies cleanly to the asset itself.
• Held inside an S-corporation, the step-up at death generally applies to the stock, not to the corporation's own basis in the property (its inside basis). So the built-in gain can survive inside the entity even after a shareholder dies. Owners who "put the rental in an S-corp to save on tax" are often the most surprised by this.
• Held through a partnership or multi-member LLC taxed as a partnership, the heir generally receives a basis adjustment in the inherited partnership interest. Whether the partnership's own basis in its assets (its inside basis) is also adjusted may depend on the §743(b)/§754 rules. That's a partnership-tax question for the entity's tax professional.

These are structural questions for the Entity domain and, above all, for your tax professional. This page names them as warnings so you know to ask. It does not tell you how to hold the asset, and choosing or changing an ownership structure for succession is not a decision to make off a web page.

State law can change the size of the reset. In community-property states, the rules can allow the entire property to step up at the first spouse's death; in common-law states, generally only the deceased spouse's share does. This turns on where you live and how title is held — a fact to raise with your professional, not a strategy to engineer here.

What this means for you

In short, a step-up in basis is real and powerful, and it's the legitimate endpoint for the deferral this domain describes. But four limits apply:

• It is a consequence of holding until death.
• It benefits your heirs rather than you.
• It addresses income tax, not estate tax.
• It can be forfeited by lifetime gifts or the wrong ownership structure.

Understanding it well changes how you weigh a long hold (see Does This STR Still Deserve My Capital?) and how you think about ever triggering the gain during life (see Should I Sell, 1031, or Refinance My STR? and the tax-bill guide). Acting on it — wills, trusts, entity structure, gifting, estate tax — is work for your own estate attorney and tax professional, every time.
