IRC § 1014 step-up basis — why Utah heirs need an appraisal even without estate tax

Most heirs of Utah real estate skip the appraisal. The estate doesn't owe federal estate tax (almost no Utah estate does, with the exemption at $13.99 million), Utah doesn't have a state estate tax, and the property is going to the heirs free and clear. The lawyer doesn't push for it. The CPA, if there is one, mentions it once and moves on. Six months later the inheritance is done, the heirs hold the property, and nobody got a date-of-death appraisal.

Then five years pass. The heirs sell. The CPA preparing Schedule D asks for the cost basis. The heirs say, "It was inherited — isn't the basis what the parents paid?" And the CPA explains the step-up rule, asks where the date-of-death appraisal is, and discovers there isn't one. Now the basis is whatever the heirs can defensibly reconstruct — county-assessor values, MLS records of a sale that didn't happen, or worse, the IRS audit position that basis is zero until proven otherwise.

The $1,000 the estate didn't spend on an appraisal becomes a $25,000 capital-gains tax problem. Below is what the basis-step-up actually does, why the documentation matters more than the math, how retrospective appraisals work for old deaths, and the Utah-specific wrinkles that come up for Transfer on Death Deed transfers and probate-avoidance trust funding.

Nothing here is legal or tax advice — that's the practitioner's call. This is the appraiser's view of what should have been done, and what to do now if it wasn't.

The 26 USC § 1014 mechanic — basis equals fair market value at death

Under IRC § 1014, the basis of property acquired from a decedent is the fair market value of the property at the date of the decedent's death (or at the alternate valuation date if elected on Form 706). The decedent's original purchase price — what they paid when they bought the home decades ago — is irrelevant to the heir's basis.

The mechanic applies whether the property transfers via will and probate, intestate succession, revocable trust distribution, beneficiary deed, or Utah's Transfer on Death Deed. The legal mechanism doesn't change the basis rule. What matters is that the transfer happens at or by reason of death.

The practical effect: when the heir later sells, capital gain is calculated as:

Sale price − (Stepped-up basis + Post-inheritance improvements) = Taxable capital gain

So the entire appreciation that occurred during the decedent's ownership disappears from the heir's tax exposure. Forty years of appreciation can vanish in one transfer. This is one of the most generous provisions in the entire Internal Revenue Code — and it is the reason high-net-worth families plan to hold appreciated assets until death rather than gifting them during life.

What the rule does NOT do: it does not eliminate gain that accrues AFTER death. If the heir holds the property for five years and it appreciates further, that post-inheritance gain is taxable when sold. The step-up resets the clock; it doesn't pause it.

A worked Utah example — Sugar House bungalow, 2010 to 2026

Make the math concrete. A 1920s brick bungalow on a tree-lined Sugar House street, 1,800 square feet, classic Salt Lake architecture. The decedent bought it in 2010 for $220,000 — Salt Lake City was still recovering from the 2008 financial crisis and prices were depressed. The owner dies in 2023. By then, the Wasatch Front housing market has run for over a decade; the appraised value on the date of death is $580,000.

Three years later, in 2026, the heir decides to sell. Cosmetic improvements during the holding period cost $15,000. The home sells for $620,000 (Salt Lake County values have continued appreciating, though more slowly than 2020-2022).

With step-up basis documented by qualified appraisal:

• Stepped-up basis at date of death: $580,000
• Plus post-inheritance improvements: $15,000
• Adjusted basis: $595,000
• Sale price: $620,000
• Taxable capital gain: $25,000
• Federal tax at 15% long-term rate: $3,750

Without basis documentation (IRS uses decedent's purchase price):

• Decedent's original basis: $220,000
• Plus improvements (if heir can document): $15,000
• Adjusted basis: $235,000
• Sale price: $620,000
• Taxable capital gain: $385,000
• Federal tax at 15% long-term rate (most of it; some at 20% for high-income heirs): roughly $58,000-$77,000

The difference between $3,750 in tax with a documented step-up and $58,000-$77,000 without it is what a $1,000 appraisal saves. The math gets more dramatic for higher-value properties (Park City vacation homes, Deer Valley estates) and for longer holding periods (homes inherited in the 1990s and sold today).

If the appraisal didn't get done at the time of death, all is not lost — see the next section.

Retrospective appraisal mechanics — how far back is too far back?

When the date-of-death appraisal wasn't commissioned at the time of death, a retrospective appraisal can be commissioned now for a past effective date. This is the second-best documentation and is widely accepted by the IRS provided the work is done by a qualified appraiser to USPAP standards.

How retrospective appraisals work:

• The effective date is the date of death. Not the date of engagement. Not the date of inspection. Not the date the report is signed. The effective date is the date the value opinion is anchored to, and for step-up basis purposes it's always the date of death.
• The comparable sales must predate the effective date. An appraiser working in 2026 for a 2018 date of death uses comparable sales that closed in 2017-2018 — not 2024-2026. The retrospective rule is that the appraiser uses only data that would have been knowable as of the effective date.
• The inspection can happen at any time. Even if the property has been renovated or sold since the date of death, the appraiser can use historical photos, county records, and the heir's records to reconstruct the condition as of the effective date. The inspection (or virtual inspection) just documents what the property looks like NOW for context.
• Data quality drives defensibility. For 2-to-10-year-old effective dates, Utah MLS data, county recorder records, and contemporary photos provide robust support. For 10-to-20-year-old dates, data is thinner but still adequate. Beyond 20 years, the appraiser leans more on broader market indices and the report's limiting conditions note the data constraints.

Retrospective work is harder than current-date appraisal, not easier — the dataset is fixed in the past, condition has to be reconstructed, and market-conditions adjustments require historical analysis. Don't engage an appraiser who quotes a retrospective at current-date fees; the work is meaningfully more involved.

Utah Transfer on Death Deeds and step-up basis

Utah's Transfer on Death Deed statute (Utah Code 75-6-401) allows a real-estate owner to designate a beneficiary who automatically takes the property at the owner's death — outside probate, with no separate court proceeding. The TOD deed is recorded during the owner's lifetime but conveys no present interest; the beneficiary's interest vests only at death.

For IRC § 1014 purposes, the TOD deed is fully equivalent to inheritance by will or trust. The property transfers at death, the basis steps up to fair market value at date of death, and the beneficiary needs the same qualified-appraisal documentation as any other heir.

What can go wrong with TOD deeds and basis documentation:

• No probate proceeding to anchor the appraisal. When a property passes via probate, the personal representative is required to file an inventory under Utah Code 75-3-706, which usually triggers the appraisal. TOD deed transfers skip probate entirely — the beneficiary takes the property by deed recording, and nobody is procedurally required to commission an appraisal. The beneficiary has to know to do it themselves.
• No estate attorney involved. TOD deeds are often used precisely because they avoid the cost of probate. The beneficiary may never speak to an attorney at all — just receives the deed, records it, and holds the property. The appraisal-for-basis-step-up advice never reaches them.
• The owner often dies suddenly. TOD deeds get used by aging owners trying to simplify their affairs. Sudden death means no thoughtful estate-administration process, no executor following a checklist, no opportunity for the family to ask "what about an appraisal?" until years later when the property sells.

The practical recommendation: anyone who is the beneficiary of a Utah TOD deed should commission a date-of-death appraisal within the first year after the owner's death. The cost is modest ($600-$1,200), the documentation is permanent, and the future tax savings can be substantial.

One appraisal, two purposes — pairing step-up with Form 706

For estates that DO file Form 706 (gross estate above $13.99 million in 2025), the date-of-death appraisal does double duty. The same USPAP-compliant report that supports the value on Schedule A of Form 706 becomes the documentation of the stepped-up basis for the heirs. Hiring one qualified appraiser, getting one report, and using it for both purposes is the standard practice.

For estates below the federal threshold (the vast majority of Utah estates), there is no Form 706 — but the basis-step-up documentation requirement remains. The same appraisal is needed, just without the 706 filing. The cost is the same.

One important nuance: if the executor elects the alternate valuation date under IRC § 2032 on Form 706, the stepped-up basis is also set as of the alternate date (not the date of death). The heirs inherit the alternate-date value. This rarely matters because the alternate election is uncommon, but for high-value estates it's worth understanding.

The appraisal is the basis. The basis is the savings. The math is straightforward.
