Date-of-death appraisals for inherited land: what executors need

When someone dies owning land, the estate usually needs to know what that land was worth on the day they died. Not today, and not when it sells, but on that specific date. That value sets the heirs' tax basis, determines whether estate tax is owed, and often decides how property is divided among family members.

An appraisal that looks back to a past date is called a retrospective appraisal. It's routine work, but it has a few requirements that ordinary appraisals don't, and land adds its own complications.

1. Why the date-of-death value matters

For most families, the most important number isn't estate tax. It's income tax basis. Under federal law, inherited property generally takes a basis equal to its fair market value at the date of death. This is the "step-up."

Say a parent bought 80 acres for $120,000 in 1985, and it was worth $1.6 million when they died. If the heirs sell for $1.7 million, their taxable gain is about $100,000, measured from the date-of-death value, not $1.58 million measured from the original price. A defensible appraisal is what supports that basis if the IRS ever asks.

Federal estate tax itself applies only to larger estates. The basic exclusion is $15 million per person in 2026. But even estates under that threshold often file an estate tax return to elect "portability," which passes a deceased spouse's unused exclusion to the survivor. That return needs values too.

2. Community property: both halves step up

California is a community property state, and that has a large and often-missed benefit. When one spouse dies, both halves of community property generally receive a new basis, not just the half that belonged to the spouse who died.

That means a surviving spouse who holds community property land should usually get a date-of-death appraisal of the whole property, even though nothing is being sold or divided yet. Years later, when the survivor sells or passes the land on, that appraisal is the record of what the basis became.

3. How a retrospective land appraisal works

The appraiser values the property as it was on the date of death, using the market as it was on that date. In practice:

• Comparable sales come from around the valuation date. Sales that happened afterward can sometimes be used to confirm a trend, but the market the appraiser is describing is the one that existed on the effective date.
• Condition is as of that date. If a barn burned down or an orchard was pulled after the death, the appraisal still reflects the property as it stood.
• The inspection is done today, so the report explains any differences between what the appraiser saw and what existed on the valuation date, using photos, aerial imagery, and family knowledge.

Retrospective appraisals can be prepared years after the death. It's common to discover the need when heirs finally sell, or when a CPA asks what basis to report.

The most important number for most families isn't estate tax. It's income tax basis.

4. What the IRS expects to see

For federal estate and income tax purposes, fair market value is defined as the price at which property would change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or sell, and both having reasonable knowledge of relevant facts. The report should apply that definition, not a quick-sale or liquidation value.

A report that holds up under examination:

• States the effective date and the definition of value clearly
• Describes the property, including legal access, zoning, water, and any leases or easements in place on that date
• Shows the comparable sales, the adjustments, and the reasoning behind them
• Addresses highest and best use, especially for land near development
• Is prepared by a qualified, credentialed appraiser and complies with USPAP

An estate may also be able to elect an alternate valuation date six months after death, but only if doing so lowers both the value of the gross estate and the estate tax owed. If your advisor is considering that election, the appraisal can include both dates.

5. California rules that catch families off guard

Property tax reassessment under Prop 19

Before 2021, California let parents pass real property to their children without a property tax reassessment. Proposition 19 narrowed that exclusion to a family home the child moves into as a primary residence, and qualifying family farms, both subject to a value cap. Most other inherited land, including vacant land, rental property, and investment acreage, is now reassessed to market value.

The county assessor sets that new assessed value, not your appraisal. But if the assessor's number looks high, a well-supported date-of-death appraisal is strong evidence in an assessment appeal.

The change-in-ownership filing

When a property owner dies, a Change in Ownership Statement (Death of Real Property Owner), form BOE-502-D, must be filed with the county assessor, generally within 150 days of the date of death. Missing it can lead to penalties.

Probate referees

If the estate goes through probate, a court-appointed probate referee values real property for the court's inventory. That value serves the court process. Many executors still commission an independent appraisal to support tax basis, to divide property fairly among beneficiaries, or for trust administration outside probate.
