TL;DR — Quick Verdict
- Under IRC Section 1014, inherited appreciated assets reset to fair market value at the owner’s death — wiping out capital gains that built up over a lifetime.
- A home bought for $200,000 and worth $800,000 at death passes to heirs with an $800,000 basis; sell immediately and the $600,000 gain owes $0 in federal capital gains tax.
- In the nine community property states, the “double step-up” resets 100% of a married couple’s shared assets — versus only 50% in common-law states. On a $2 million portfolio, that difference can save the survivor $150,000+ in tax.
- The 2026 federal estate tax exemption is $15 million per person ($30 million per couple), so the step-up benefits nearly everyone while estate tax hits almost no one.
- The single biggest mistake is gifting appreciated assets before death — a gift carries the old basis and forfeits the step-up entirely.
- Verdict: For appreciated assets you plan to hold, inheriting almost always beats gifting. Confirm your titling and community-property status now, while both spouses are alive.
Roughly $84 trillion is expected to change hands through inheritance over the next two decades, according to consulting firm Cerulli Associates — and a large share of it will move tax-free thanks to a single, often-misunderstood provision of the Internal Revenue Code. When someone dies owning appreciated stock, real estate, or a business interest, the asset’s cost basis “steps up” to its fair market value on the date of death. Decades of untaxed gains simply vanish for income tax purposes.
The mechanics matter enormously. A retiree who bought Apple stock in 1995 or a rental property in the 1980s may be sitting on gains that would trigger a six-figure tax bill if sold during life. Held until death, that same asset can pass to heirs with the gain erased. Fidelity and the IRS both describe this reset as one of the most powerful features of the U.S. tax code for ordinary families.
This report shows exactly how the step-up works, quantifies the community-property “double step-up” that favors couples in nine states, models real dollar savings, and details the titling and gifting mistakes that quietly cost heirs tens of thousands. Every figure is drawn from IRS guidance and the tax code itself.
How the Step-Up in Basis Actually Works
Cost basis is what you paid for an asset, adjusted for improvements and depreciation. Capital gains tax applies to the difference between your sale price and that basis. The step-up rule, codified at IRC Section 1014(a), replaces the decedent’s original basis with the asset’s fair market value on the date of death. The heir inherits both the higher basis and — per IRS rules — automatic long-term holding status, unlocking the preferential long-term capital gains rates regardless of how briefly they hold the asset.
Consider a concrete case. Margaret bought a rental duplex in 1988 for $150,000. By her death in 2026 it appraises at $650,000. Had she sold it the day before dying, her $500,000 gain (minus depreciation recapture) would have generated a substantial tax bill. Instead, her son inherits the property with a fresh $650,000 basis. If he sells within months for $660,000, he owes long-term capital gains tax only on the $10,000 of post-death appreciation — not on 38 years of growth.
The executor may elect an alternate valuation date six months after death instead of the date of death, which can lower the estate’s value in a falling market. One critical exclusion applies: assets classified as income in respect of a decedent — traditional IRAs, 401(k)s, and annuities — get no step-up. Heirs of those accounts still owe ordinary income tax on every dollar withdrawn, which is why inherited retirement account withdrawal rules demand separate planning.
The 2026 Tax Figures That Drive the Strategy
The step-up’s value depends on the capital gains rates it lets heirs avoid and the estate tax threshold above which a different calculus applies. Both were reset for 2026. The table below consolidates the federal figures that govern every step-up decision this year.

The $15 million exemption, made permanent by the 2025 federal tax law, reframes the entire strategy. Because fewer than one estate in a thousand now owes any federal estate tax, the old fear of estate tax rarely justifies giving up the income-tax step-up. For all but the wealthiest families, maximizing basis reset — not minimizing estate size — is the winning move. Families anxious about state-level exposure should still check the separate federal estate tax threshold and who it affects against their state’s rules.
Common-Law vs. Community Property: The Double Step-Up
Where you live changes the math dramatically. In the 41 common-law states, jointly owned property gets a step-up only on the deceased spouse’s half. The survivor keeps their original low basis on the other half. In the nine community property states — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin — IRC Section 1014(b)(6) resets 100% of qualifying community property when the first spouse dies. IRS Publication 555 confirms the entire asset’s fair market value becomes the new basis.
Picture a couple who bought a stock portfolio for $200,000 that is now worth $2 million. In a common-law state, one spouse’s death steps up only half: the basis rises to roughly $1.1 million, leaving about $900,000 of gain still baked in. Sell the whole portfolio and the survivor faces tax on that $900,000. In a community property state, the same death resets the full $2 million. The survivor can sell the next day with zero capital gains. At a combined 23.8% rate, that titling difference is worth well over $150,000.
Verdict
For married couples holding heavily appreciated assets, community property titling is decisively better — it can double the step-up and erase six figures of capital gains. Couples in the five elective states (Alaska, Florida, Kentucky, South Dakota, and Tennessee) can pursue similar treatment through a community property trust, though the IRS has not fully settled that question. Couples in the remaining common-law states cannot access the double step-up and should plan around the 50% reset instead.
The catch is documentation. Simply being married does not confer community property status; the asset must be titled and characterized as community property, ideally purchased with community funds during the marriage. Retitling separate property into community property carries its own legal and creditor consequences, so this is a decision for a qualified attorney — and one that must be made while both spouses are living.
Step-Up vs. Lifetime Gifting: Which Wins?
Families often assume giving assets away before death is the generous, tax-smart choice. For appreciated property, the opposite is usually true. A lifetime gift under IRC Section 1015 carries over the giver’s original basis — the recipient inherits the low basis and the full built-in gain. Waiting for death triggers the Section 1014 step-up instead, wiping that gain out.
Run the numbers on a $500,000 asset with a $100,000 basis. Gift it during life and the recipient keeps the $100,000 basis; selling for $500,000 produces a $400,000 taxable gain — roughly $95,200 in tax at the 23.8% top effective rate. Let the same asset pass at death and the basis steps up to $500,000; an immediate sale produces zero gain and zero tax. The step-up path saves the family the entire $95,200.

Verdict
For appreciated assets held by someone whose estate is below the $15 million exemption, inheriting beats gifting nearly every time. Gifting makes sense mainly for cash, assets that have lost value, or estates large enough to face estate tax — where removing future appreciation outweighs the lost step-up. When in doubt, appreciated assets stay put.
What Most People Get Wrong
The step-up is generous, but it is easy to forfeit. Four mistakes recur often enough that estate attorneys see them weekly.
Mistake 1 — Gifting appreciated assets to dodge probate. Adding an adult child to a deed or handing over stock during life feels efficient. The consequence is a carryover basis: the child inherits decades of gain and a tax bill that death would have erased. The correct action is to use a revocable living trust or a transfer-on-death deed, which keeps the asset in the estate for step-up purposes while still bypassing probate. Compare the mechanics against other probate avoidance strategies and their costs before retitling anything.
Mistake 2 — Ignoring the one-year gift-back rule. Under IRC Section 1014(e), if you gift an appreciated asset to a dying person and it returns to you (or your spouse) within one year of their death, the step-up is denied. Families attempting to “harvest” a step-up from a terminally ill relative often trip this wire. The correct action is to route such assets to a trust for other beneficiaries rather than straight back to the original donor.
Mistake 3 — Assuming irrevocable trust assets get a step-up. IRS Revenue Ruling 2023-2 confirmed that assets in an irrevocable grantor trust not included in the decedent’s gross estate receive no step-up. Many families set up these trusts for creditor protection and are blindsided at death. The fix is deliberate drafting — granting the grantor a power that forces estate inclusion when a step-up is the priority.
Mistake 4 — Failing to document date-of-death value. Without a qualified appraisal or brokerage statement fixing fair market value at death, the IRS can challenge the heir’s claimed basis years later when the asset sells. The correct action is to obtain a formal valuation immediately, a step that also feeds the executor’s duties and fee obligations.
Who Should Prioritize This — And Is It Worth It?
The step-up rewards specific profiles more than others. If you own long-held real estate, a concentrated stock position, or a family business with a low basis, the reset is the centerpiece of your plan — potentially worth more than any other single move. Retirees sitting on a primary residence bought decades ago frequently hold gains that dwarf their other assets, making the step-up the difference between heirs keeping or selling the home.
Married couples in community property states have the strongest case of all: coordinating titling now can double the eventual reset. Couples in common-law states should still weigh a community property trust in an elective state if their appreciated holdings are large. By contrast, if your assets are mostly cash, recently purchased, or held in retirement accounts that never step up, the strategy offers little — your energy belongs elsewhere in the estate plan.
The break-even is easy to see. The planning cost — a living trust, updated deeds, an attorney consultation — typically runs a few thousand dollars. The tax saved on a single appreciated property can reach $100,000 or more. For anyone holding assets that have doubled or tripled since purchase, the step-up is unambiguously worth the effort. Families also weighing a near-term sale should read how the tax implications of selling inherited property interact with the fresh basis before listing.
Frequently Asked Questions
Does inherited property get a step-up if the estate owes no estate tax?
Yes. The step-up under IRC Section 1014 applies regardless of estate size. With the 2026 federal exemption at $15 million per person, almost no estate owes federal estate tax, yet virtually every inherited appreciated asset still resets to fair market value at death. The two systems operate independently — you get the income-tax step-up even when zero estate tax is due.
Do retirement accounts like IRAs get a step-up in basis?
No. Traditional IRAs, 401(k)s, and annuities are classified as income in respect of a decedent under IRC Section 691 and are explicitly excluded from the step-up. Heirs owe ordinary income tax on every dollar withdrawn, at rates up to 37%. This is why estate planners often direct such accounts to charities or lower-bracket heirs while steering step-up-eligible assets like stock and real estate to individuals.
Which states allow the double step-up in basis?
The nine community property states — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin — allow a full 100% step-up on qualifying community property under IRC Section 1014(b)(6). Five additional states (Alaska, Florida, Kentucky, South Dakota, and Tennessee) permit elective community property trusts that may achieve the same result, though the IRS has not conclusively confirmed that treatment.
Can I get a step-up by gifting assets to a dying relative?
Rarely, and it is risky. IRC Section 1014(e) denies the step-up if you gift an appreciated asset to someone who dies within one year and the asset passes back to you or your spouse. The one-year window blocks the most obvious “basis harvesting” attempts. Structuring the bequest to pass to other beneficiaries through a trust can preserve the step-up, but this requires careful legal drafting.
How We Researched This Article
This analysis is built entirely on primary federal tax authorities. The core step-up mechanism comes from Internal Revenue Code Section 1014 and the corresponding gift-basis rules at Section 1015, cross-referenced against IRS Publication 551 (Basis of Assets) and Publication 555 (Community Property) for the treatment of inherited and community property. The community property double step-up rests on IRC Section 1014(b)(6), and the one-year gift-back limitation on Section 1014(e). The exclusion of irrevocable grantor trust assets reflects IRS Revenue Ruling 2023-2.
The 2026 tax figures were verified against IRS Revenue Procedure 2025-32 for long-term capital gains thresholds and against IRS estate tax guidance implementing the 2025 federal tax law for the $15 million per-person exemption. Net Investment Income Tax thresholds derive from IRC Section 1411. Readers can confirm the underlying code at the Cornell Legal Information Institute, review official guidance at the Internal Revenue Service, and cross-check inflation-adjusted brackets through the Tax Foundation.
All dollar illustrations — the $600,000 home gain, the $2 million portfolio, the $500,000 gift-versus-inheritance comparison — are modeled scenarios using verified 2026 rates, not measured averages, and are labeled as such. They assume federal treatment only; state income and estate taxes vary and can materially change outcomes. Because community property characterization and trust inclusion turn on individual facts, these figures illustrate the framework rather than predict any specific result.
