Stepped-Up Basis for Real Estate Investors (2026)

When a real estate investor dies and leaves a rental property to their heirs, something remarkable happens: the property's tax basis — the number that determines how much gain gets taxed — is reset to fair market value on the date of death. All the accumulated depreciation recapture, all the deferred capital gains from decades of appreciation, are permanently and completely eliminated. Not deferred. Eliminated. This is the stepped-up basis rule under IRC § 1014, and for long-term real estate investors, it is one of the most powerful tax strategies in the code.

What is stepped-up basis?

Under IRC § 1014, a heir's cost basis in property received from a decedent is equal to the property's fair market value on the date of death (or an alternate valuation date elected by the estate).¹ The heir didn't pay that amount — the step-up is purely a tax construct that treats the property as if the heir had purchased it fresh at the date-of-death value.

The practical consequence is enormous for rental property holders: all of the following are reset to zero at the new stepped-up basis:

• §1245 recapture (ordinary income on accelerated/bonus depreciation from cost segregation)
• §1250 unrecaptured gain (the 25%-capped recapture on straight-line building depreciation)
• Long-term capital gains (appreciation above the original purchase price)
• Net Investment Income Tax exposure (3.8% NIIT on the deferred gain)

If the heir sells the property immediately after inheriting it at the FMV that became their basis, they owe no federal tax whatsoever on any of it.

The four-layer tax stack that disappears

Real estate investors who sell a rental face a layered tax bill that many don't fully appreciate until they're looking at a closing statement. A property with cost segregation and 20+ years of appreciation can face all four layers stacked:

A 1031 exchange defers all four layers. An installment sale spreads layers 2–4 across years (but front-loads §1245 in year one). A stepped-up basis at death permanently eliminates all four layers, with no exchange timing rules to navigate and no replacement property to find.

Worked example: $214,000 in tax permanently erased

Consider a realistic long-hold scenario:

Property history: Residential rental purchased in 2006 for $500,000 (land $100K, building $400K). Cost segregation study done in 2010 — $80,000 of 5/7/15-year components fully expensed via bonus depreciation (§1245 recapture pool = $80,000). Remaining $320,000 building depreciated straight-line over 27.5 years; by 2026 that's 16 years of depreciation: $320,000 ÷ 27.5 × 16 = $186,182 (rounded to $186,000, all §1250 recapture).

Adjusted basis at sale: $500,000 − $80,000 (§1245 dep) − $186,000 (§1250 dep) = $234,000

Current FMV (2026): $1,100,000. Selling costs: $60,000 (5.5%). Amount realized: $1,040,000. Total gain: $1,040,000 − $234,000 = $806,000.

Tax if sold today (MFJ investor with $275,000 other income, passive property — not REPS):

If this investor lives in California, add 13.3% state tax on the entire $806,000 gain — another ~$107,198. Total tax burden: $321,926.

The community property advantage: a double step-up

For married couples in one of the nine community property states — Arizona, California, Idaho, Louisiana, New Mexico, Nevada, Texas, Washington, and Wisconsin — the step-up in basis works even better at the first spouse's death.³

In common-law (non-community property) states, a property held as joint tenants with right of survivorship gets only a half step-up when the first spouse dies. The surviving spouse's original half retains its old carryover basis; only the decedent's 50% share steps up to FMV.

In community property states, the entire property — both spouses' shares — steps up to FMV at the first spouse's death under IRC §1014(b)(6). The surviving spouse can then sell the property with a full step-up basis and owe zero federal tax.

Example: A California couple bought a rental in 2000 for $350,000 that's now worth $1,100,000. Accumulated depreciation of $250,000. If spouse A dies in 2026:

• Community property (CA): Surviving spouse's entire basis steps up to $1,100,000. Sells for $1,100,000 → $0 gain → $0 federal or state tax.
• Common-law state (JTWROS): Only 50% steps up. Surviving spouse's basis = $175,000 (their original half) + $550,000 (decedent's stepped-up half) = $725,000. Sell for $1,100,000 → $375,000 gain → substantial tax bill.

Investors in community property states who hold appreciated real estate in joint tenancy should confirm how their state characterizes the property — and whether their estate documents are structured to preserve community property treatment.

The gift trap: why gifting real estate is usually worse than bequeathing it

It's common for real estate investors to consider gifting appreciated property to children — whether for estate tax reasons or to shift income to a lower bracket. But gifting real estate triggers the carryover basis rule under IRC §1015: the recipient takes the donor's basis, not the property's fair market value.⁴

In our example above: if the investor gifts the property to their child instead of bequeathing it, the child inherits a $234,000 carryover basis. When the child eventually sells, they face the same $806,000 gain — the entire four-layer tax stack — that the parent was trying to avoid. The $214,728 federal tax bill travels with the basis, not with the donor.

The gift vs bequest calculus changes when the estate is large enough that the estate tax applies (above $15 million per person in 2026). In that case, gifting now can reduce the taxable estate — but the income tax cost of the carryover basis must be modeled against the estate tax savings. That's exactly the scenario where a specialist advisor earns their fee.

Trust planning: preserving (or losing) the step-up

How real estate is held in trust significantly affects whether heirs receive a stepped-up basis:

Revocable living trusts — the most common estate planning tool — are grantor trusts for tax purposes. Assets held in a revocable trust receive a full IRC §1014 step-up at death. The trust does not protect the step-up; it simply passes it through.⁵

Irrevocable trusts vary significantly. Assets transferred to a completed-gift irrevocable trust generally lose the step-up — the grantor no longer owns the asset for estate tax (or IRC §1014) purposes. However:

• Intentionally Defective Grantor Trusts (IDGTs): taxed as grantor trusts for income tax but excluded from the taxable estate. Assets are generally not included in the estate for §1014 purposes, so they don't get a step-up. This creates a tension: IDGTs reduce estate tax but forfeit the step-up in basis.
• §2036 retained interest trusts: if the grantor retains a qualifying interest (such as in a Grantor Retained Annuity Trust), IRC §2036 pulls the property back into the taxable estate — meaning the step-up is preserved.

For most investors well below the $15M estate exemption, the step-up in basis is far more valuable than any irrevocable trust structure. With OBBBA making the $15M exemption permanent, very few real estate investors need to sacrifice the step-up for estate tax reasons.

OBBBA context: $15M exemption + step-up = most portfolios pass tax-free

Before the One Big Beautiful Bill Act (signed July 4, 2025), the estate tax exemption was scheduled to revert to approximately $7M in 2026 — creating pressure for large-portfolio investors to engage in complex estate planning. The OBBBA made the $15M per-person exemption permanent ($30M for married couples) and indexed it for inflation starting in 2027.⁶

The practical result for most real estate investors:

• A portfolio worth $14M passes to heirs entirely free of federal estate tax — and with a full stepped-up basis on every property.
• Heirs can sell any or all properties immediately with zero federal income tax on all prior appreciation and depreciation.
• The complexity of irrevocable trust structures designed to reduce estate tax is unnecessary for most families with sub-$15M portfolios.

At $30M exemption per couple, even many commercial real estate portfolios that previously required aggressive planning now pass cleanly through a simple revocable trust + step-up structure.

The 1031-until-death cascade: the ultimate REI tax strategy

The most powerful application of the step-up in basis is combining it with the 1031 exchange to run a "1031 cascade" — a series of exchanges that keeps deferred gain rolling forward across multiple properties over a lifetime, until death permanently eliminates it all at once.

How it works:

1. Investor buys first rental for $300K in 1995.
2. Sells (1031) → replaces with $600K property in 2005. Deferred gain carries forward.
3. Sells (1031) → replaces with $1.5M commercial building in 2015. Deferred gain grows.
4. Investor dies in 2030. Property FMV: $2.8M. Heir's new basis: $2.8M.
5. Heir sells for $2.8M → $0 gain → $0 tax — on 35 years of compounded appreciation and depreciation accumulation.

The 1031 exchange defers but doesn't eliminate. The step-up eliminates. Together, they create a tax elimination strategy across an entire investing lifetime. A DST (Delaware Statutory Trust) can play the role of the final replacement property — providing passive income during late-career years, no active management, and a step-up at death to clear the accumulated deferred gain.⁷

When to consider alternatives to holding until death

The step-up strategy assumes the investor holds the property until death. That's not always the right plan:

• Need liquidity now. Real estate is illiquid. If the investor needs cash — for retirement income, medical costs, or other investments — holding to death isn't viable. An installment sale or a 1031 into a higher-income property may be better.
• Estate concentration risk. A portfolio that's 90% real estate with adult children who don't want landlord responsibilities creates a liquidity problem at death. Heirs selling multiple properties simultaneously often accept lower prices. Life insurance held in an irrevocable life insurance trust (ILIT) can provide liquidity without losing the step-up on the real estate.
• Property is losing value. A stepped-down basis (property worth less at death than purchase price) is allowed under §1014 but works against heirs — they inherit a lower basis. A loss-generating property may be better sold during life to recognize the loss against other income.
• Passive losses locked in carryforward. Suspended PAL carryforwards under IRC §469 don't get a step-up at death — they're gone. An investor with large suspended losses might consider a lifetime disposition to release those losses rather than letting them expire unused. See our passive activity loss guide for how to model this.
