Stepped-Up Basis: The Inherited Home Tax Guide 2026
Stepped-up basis (IRC §1014): basis resets to FMV at date of death. Parent bought $150K; dies at $520K; sell at $525K = $750 tax (not $85K+). 3 scenarios: sell quickly (minimal); hold (appreciation taxable); move in 2yr (Section 121 excludes $250K gain). Get date-of-death appraisal within 30 days. Rental recapture: 25% on depreciation taken. Own Luxury Homes® 12-Point Agent Integrity Audit™ — inherited property specialists.
Stepped-Up Basis Explained: The Inherited Home Tax Rule That Saves Most Heirs Tens of Thousands of Dollars
The stepped-up basis is the most powerful tax gift built into American inheritance law. It is also the most misunderstood. Heirs who don’t know about it make decisions — waiting to sell, renting the property, not getting an appraisal — that accidentally reduce or eliminate its protection. This guide explains exactly how it works, what actions preserve it, and what actions erode it.
The Stepped-Up Basis Explained With Real Numbers
Three Scenarios: The Same Property, Three Different Tax Outcomes
The property: purchased by parent in 2000 for $150,000. Value at date of death: $520,000. Scenario A: Heir sells within 6 months of death. Sale price: $525,000. Stepped-up basis: $520,000. Taxable gain: $5,000. Federal capital gains (15%): $750. Total tax: approximately $750. Scenario B: Heir waits 3 years. Home appreciates to $590,000. Sells. Stepped-up basis: $520,000 (unchanged from date of death). Taxable gain: $70,000. Federal capital gains (15%): $10,500. Total tax: approximately $10,500. Scenario C: Heir moves in for 2+ years, then sells at $590,000. Qualifies for Section 121 exclusion ($250,000 single). $70,000 gain < $250,000 exclusion. Total tax: $0. The lesson: the right strategy depends on whether you want to sell quickly (minimal tax), hold (growing taxable appreciation), or move in (Section 121 protection on top of stepped-up basis).
What the Stepped-Up Basis Does NOT Protect Against
The Three Situations Where You Still Owe Tax
Situation 1: Holding the property and it appreciates. Any appreciation above the stepped-up basis after the date of death is taxable when you eventually sell. The tax clock restarts at death, not at the original purchase — but it does restart. Situation 2: Converting to rental and then selling. When you rent an inherited property, you depreciate it based on the stepped-up basis (good). But when you sell: depreciation recapture applies. The depreciation you took reduces your basis further. The recapture tax rate is 25% on the depreciation amount. Example: $520,000 stepped-up basis; $15,000 in depreciation taken over 2 years; sale at $560,000; Depreciation recapture: $15,000 × 25% = $3,750. Gain above basis: ($560,000 − $520,000 + $15,000 depreciation) = $55,000 at 15% = $8,250. Total: $12,000 in tax on a $560,000 sale. Still manageable, but not $0. Situation 3: Inheriting in a state with inheritance tax. Six states (Iowa, Kentucky, Maryland, Nebraska, New Jersey, Pennsylvania) impose inheritance tax on the heir, not the estate. Rates vary by state and by relationship to the deceased. Surviving spouses are usually exempt. Children: often lower rates. Unrelated heirs: higher rates. Check your specific state.
The Documentation Checklist: Protecting Your Basis
| Document | Purpose | When to Get It | From Whom | ||||||
|---|---|---|---|---|---|---|---|---|---|
| Date-of-death appraisal | Establishes fair market value; becomes your stepped-up basis; primary IRS defense document | Within 6 months of death (sooner is better) | Certified residential appraiser licensed in the state where property is located | ||||||
| Executor/administrator appointment | Establishes legal authority to act on behalf of the estate | As soon as probate opens | Probate court in the state where property is located | ||||||
| Death certificate (multiple certified copies) | Required by every institution to establish death and transfer authority | Immediately; request 8–10 certified copies | County recorder or vital records office | ||||||
| Title search and property history | Confirms clean title; reveals any liens or encumbrances | Before any sale or refinance | Title company or real estate attorney | ||||||
| Property tax records | Shows assessed value (different from fair market value); needed for ongoing tax obligations | Within 30 days of death | County assessor's office | ||||||
| Existing mortgage statement (if any) | Shows payoff amount; confirms Garn-St. Germain rights (no acceleration on death) | Within 30 days of death | Mortgage servicer | ||||||
| Homeowner’s insurance policy | Must notify insurer of ownership change; coverage may lapse if not updated | Within 30 days of death | Current insurer | ||||||
| Do not sell or transfer inherited property without consulting an estate attorney and CPA first. The specific sequence of actions affects both your legal title and your tax outcome. | |||||||||
“The appraisal urgency conversation: "It’s been 9 months since my father died. We haven’t sold the house yet. Did we miss the window for the stepped-up basis?" "No — the stepped-up basis doesn’t expire. Your basis was set at the date of death and stays at that value. What you may have missed is the ability to document it accurately. A retrospective appraisal dated to 9 months ago is possible but more difficult for an appraiser to support defensively than one done at the time of death. Is there a reasonable estimate we can support? Were there any comparable sales around that date we can reference? This is what a qualified appraiser will look at. The lesson going forward: the appraisal should be ordered within the first 30 days of death for any real estate asset in the estate. It is the most important tax-protection document you can have for inherited property — and at $400–$800, it is also one of the cheapest relative to what it protects."”

What is stepped-up basis on inherited property?
Stepped-up basis (IRC §1014) means that when you inherit a property, your cost basis for tax purposes is reset to the fair market value at the date of the previous owner’s death — not the original purchase price. A parent who bought a home for $100,000 and it’s worth $600,000 at death: your basis is $600,000. If you sell at $600,000: $0 capital gains tax. The $500,000 of appreciation during the parent’s ownership is never taxed to the heir. To protect this benefit: order a qualified appraisal within 30 days of death; document the stepped-up value clearly; consult a CPA before any sale, rental, or transfer decision.
