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 circles the same quantity: your adjusted basis. When you dispose of a short-term rental, your gain is measured using the amount realized and your adjusted basis — and the basis is not simply the price you paid: it's what you paid, plus capital improvements, minus all the depreciation you claimed along the way (P53 builds the basis; the Exit-Tax Anatomy page assembles 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 the whole Wealth & Exit domain keeps returning to: the tax you defer through depreciation and through tools like the 1031 exchange doesn't disappear — it rides forward inside a lower and lower basis.

This page is about where that carried-forward gain can actually stop being owed — not deferred again, but resolved — in the hands of whoever inherits the property. And the mechanism is not a clever transaction. It'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, the very built-in gain that a lifetime sale would have surfaced — the appreciation, and the specific depreciation-related pieces that P54 and the Exit-Tax Anatomy page break down by character — is measured against a fresh, higher basis for the heir. This is where gain carried during the owner's lifetime can cease to be built-in gain in the heir's hands. The exact character mechanics of how a lifetime sale would have taxed those pieces belong to P54 and the Exit-Tax Anatomy node; this page's job is the plainer point: 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 you access the property's value without selling is by borrowing against it (a refinance, which the Financing domain covers, and which is not itself a taxable event). The step-up arrives only after you're gone, for someone else.

It can eliminate the inherited built-in income-tax gain — it does not answer the estate-tax question. Those are two different regimes. 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 the thing 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, and it connects directly to P58's question of whether a property still deserves your capital — a step-up can be one honest reason a long hold is rational, but it is not free optionality.

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. In every case the pattern is the same: name the trap, then take it to a professional — because 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 rides along, intact. The instinct to "just put the kids on the deed now" is the classic own-goal: it can replace a potential future §1014 basis reset with carryover basis under §1015. Gift versus bequest is a genuine fork with very different tax outcomes, and which side you want is an estate-planning decision for your attorney and tax pro.

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

• 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 inside basis in the property — 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, while an adjustment to the partnership's inside basis in its assets may depend on the §743(b)/§754 rules. That's a partnership-tax question for the entity's tax professional.

These are structural questions that sit with the Entity domain and, critically, with 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

The honest summary is short. A step-up in basis is real, it's powerful, and it's the legitimate endpoint the domain's deferral arc has been pointing at — but it is a consequence of holding until death, it benefits your heirs rather than you, it addresses income tax and not estate tax, and it can be quietly forfeited by lifetime gifts or the wrong ownership wrapper. Understanding it well changes how you weigh a long hold (see P58) and how you think about ever triggering the gain during life (see P56 and the Exit-Tax Anatomy page). Acting on it — wills, trusts, entity structure, gifting, estate tax — is work for your own estate attorney and tax professional, every time.

The bottom line

Depreciation and deferral don't erase an STR's tax — they carry it forward inside a shrinking basis. Section 1014 is where gain carried during the owner's lifetime can cease to be built-in gain in the heir's hands: at death, an heir's basis generally resets under the inherited-property basis rules, so gain a lifetime sale would have surfaced may no longer be present in the same way for the heir. But it's a consequence of holding, not a lever you pull; it helps your heirs, not you; it's about income tax, not estate tax; and lifetime gifts or the wrong ownership wrapper can give it away. Know what it does — then take every actionable estate and entity decision to your own attorney and tax professional.
