Stepped-up basis is the reset of an inherited asset’s cost basis to its fair market value at the owner’s death. Appreciation during the decedent’s lifetime — including gains deferred through decades of exchanges — simply disappears for income-tax purposes, making the step-up the most consequential rule in long-horizon real estate and alternatives planning.
How the step-up works
Under IRC Section 1014, property acquired from a decedent takes a basis equal to date-of-death fair market value (or the alternate valuation date). An investor who bought a property for $500,000, depreciated it to a $200,000 adjusted basis, and dies when it’s worth $2 million passes heirs an asset with a $2 million basis: the $1.8 million of gain — and the accumulated depreciation recapture inside it — is never income-taxed. Heirs can sell immediately with little or no gain, or hold and depreciate again from the stepped-up basis, restarting the shelter. Basis can also step down if values fell; community-property states can double the benefit on both spouses’ halves; and assets that bypass the estate mechanism — notably retirement accounts and income in respect of a decedent — get no step-up, a mapping worth keeping precise in client conversations.
Why it anchors alternatives strategy. The step-up converts deferral into elimination: the entire logic of swap till you drop — serial 1031 exchanges into progressively more passive holdings like DSTs, and even a terminal 721 exchange into operating partnership units (which also generally step up at death) — is a race between the tax bill and the estate plan that the estate plan is designed to win. The rule interacts with estate tax rather than replacing planning: the step-up erases income tax on appreciation, while estate tax applies (above the exemption) on the same value — for most estates under the exemption, the step-up is close to a free elimination of a lifetime’s deferred gains.
Perennial caveat for anything written down: the step-up is a recurring target of reform proposals (repeal, carryover basis, gain-at-death regimes have all been floated across administrations), so long-horizon strategies premised on it carry legislative risk worth acknowledging — current law is generous, and “current” is doing work in that sentence.
FAQ
What is stepped-up basis in simple terms?
When you inherit an asset, its cost basis resets to its value at the owner’s death — the gains that built up during their lifetime are never income-taxed.
Does stepped-up basis eliminate depreciation recapture?
Generally yes — the reset basis wipes the deferred gain and the recapture liability that traveled with it, which is the endgame of serial 1031 strategies.
Do all inherited assets get a step-up?
No — retirement accounts (IRAs, 401(k)s) and income in respect of a decedent don’t; jointly held and community property follow their own rules. The asset’s path through the estate determines the treatment.
