Inherited Property Basis and Date-of-Death Valuation

When an heir sells inherited property, gain or loss is usually measured from a basis tied to the decedent’s date of death, rather than the decedent’s original purchase price. This is often called a step-up in basis, but the adjustment can also be downward if the property’s fair market value fell. The planning question is to establish the correct basis and retain support for it before calculating gain or loss.

The general basis rule

For property acquired from a decedent, the usual basis is fair market value (FMV) on the date of death. If an estate qualifies for and elects the alternate valuation method for federal estate-tax purposes, the relevant value may instead be determined under that election. Some property may receive special-use valuation, and special rules apply to certain excluded conservation-easement value and other categories. The estate’s reported value and the beneficiary’s records should be reconciled rather than assuming every asset uses the same number.

Suppose a decedent bought shares for $20,000, and their FMV at death is $52,000. If the ordinary date-of-death rule applies, the heir’s initial basis is generally $52,000. If the heir later sells them for $58,000, the preliminary gain is $6,000 before considering selling costs and any other relevant adjustments. If the shares were worth only $14,000 at death, the general basis would generally be $14,000; the rule is not always an increase.

Alternate valuation is an estate election

The alternate valuation election is generally made by the estate’s personal representative on the estate-tax return when the statutory requirements are met. It is not an election the beneficiary makes independently just because the property fell in value. The election generally values property at the earlier of its distribution or six months after death and must satisfy the estate-tax rules, including the requirement that it reduce both the gross estate value and estate tax. Review the Form 706 instructions for the applicable year and estate facts.

For example, if an estate properly elects alternate valuation and stock is distributed to an heir three months after death, the relevant estate value is generally based on the distribution-date value under the election. Property still held at the six-month date is generally valued then. The exact basis therefore depends on the estate’s election and the timing of distribution, not merely on a beneficiary’s preferred measurement date.

Inherited basis is usually long-term holding period

If inherited property is a capital asset and the heir later disposes of it, the gain or loss is generally treated as long-term regardless of how long the heir personally held it. This avoids a short-term result when the heir sells soon after receiving the asset. Determine basis, amount realized, and character separately: the holding-period rule does not itself tell you whether the sale produced a gain, a loss, or a particular tax amount.

Important exceptions and adjustments

Property returned to the original donor shortly before death

A special anti-abuse rule can prevent a basis adjustment for appreciated property if the decedent acquired the property by gift from the heir or the heir’s spouse within one year before death, and it passes back to that donor. In the circumstances described by the IRS, basis may remain tied to the decedent’s adjusted basis instead of receiving the usual date-of-death FMV. Analyze the direction and timing of the transfer; do not assume that every asset held by a decedent gets a fair-market-value reset.

Special-use valuation for a farm or closely held business

A qualified estate may elect special-use valuation for certain real property used in farming or a closely held business. A qualifying heir’s initial basis may reflect the special-use value rather than ordinary FMV. If the heir later stops using the property in a qualifying way or transfers it to a nonfamily member within the recapture period, additional estate tax may apply. The code has specific eligibility, use, ownership, election, and recapture requirements; treat special-use valuation as a distinct rule, not a routine alternative basis method.

Community property and jointly owned assets

Community-property rules can adjust the basis of both halves of qualifying community property when a spouse dies, subject to statutory conditions. Jointly owned property, tenancy by the entirety, qualified joint interests, retirement accounts, and assets passing by beneficiary designation may have rules that differ from a simple probate transfer. Determine ownership form and the decedent’s included share before applying the general rule to the whole asset.

Consistent basis reporting for certain estates

For estates required to file Form 706, certain beneficiaries must use the estate-tax value reported for inherited property under the consistent-basis rules and may receive Schedule A to Form 8971 from the executor. This connects the estate’s reported value with the beneficiary’s tax basis. A beneficiary should not replace the reported figure with an unsupported estimate. If a Schedule A is missing or appears inconsistent, request clarification and preserve valuation records.

Basis is not necessarily the same as a sale price

FMV at death is a valuation at a point in time, commonly supported by an appraisal, market quotation, or other evidence appropriate to the asset. A later sale price can be higher or lower because markets change, the property condition changes, or the sale terms differ. The sale price does not retroactively set the inherited basis simply because it is the first observable transaction after death.

For publicly traded securities, date-specific market data can often support the value. Real estate, closely held business interests, art, and other unique assets may require a qualified appraisal. If the estate used an alternate or special-use method, obtain the relevant estate-tax reporting and election records. A defensible basis file should show the asset description, valuation date, valuation method, reported amount, later capital improvements, distributions, and disposition costs.

Calculate gain or loss when the beneficiary sells

Start with the beneficiary’s adjusted basis. Compare it with amount realized, generally the sale proceeds reduced by applicable selling expenses. If the proceeds exceed adjusted basis, the difference is generally gain; if lower, it is generally loss, subject to the rules for the asset and transaction. Capital improvements made after inheritance can increase basis, while depreciation claimed on rental or business property can reduce adjusted basis. Do not use the initial inherited value as a permanent number if post-inheritance tax adjustments occur.

Example: an heir receives a rental property with an inherited basis of $400,000, later makes $30,000 of capital improvements, claims $12,000 of depreciation, and then sells it for net proceeds of $455,000. Before considering other items, adjusted basis is $418,000 and the preliminary gain is $37,000. The gain’s character and any depreciation-related consequences require separate analysis. This illustrates why basis records must continue after the inheritance.

Common planning and exam errors

• Calling the rule a guaranteed step-up. FMV below the decedent’s basis can produce a step-down.
• Using the decedent’s purchase price as the heir’s basis without testing the inherited-property rules.
• Letting the heir choose an alternate valuation date independently of the estate’s election.
• Assuming every asset in a spouse’s name or a jointly held account receives the same basis adjustment.
• Ignoring the one-year transfer-back rule, special-use valuation, or community-property treatment.
• Treating FMV at death as the amount the heir must report on a later sale even after improvements, depreciation, or other basis adjustments.
• Assuming a recent sale alone proves the date-of-death value without considering changes in condition or market conditions.
• Applying a short-term holding period because the heir sold within one year of distribution.

A basis-document checklist

1. Identify the asset, ownership form, transfer path, and decedent’s date of death.
2. Obtain the date-of-death valuation or the estate’s valid alternate or special-use valuation records.
3. Review Form 706 reporting and Schedule A to Form 8971 when applicable.
4. Check for special rules such as a recent gift from the beneficiary, community-property treatment, or joint ownership.
5. Track post-death improvements, depreciation, distributions, and other basis adjustments.
6. When the asset is sold, calculate amount realized and character separately from the basis determination.

Exam takeaway

The general inherited-property basis is date-of-death FMV, with a possible valid alternate valuation election. That basis can rise or fall relative to the decedent’s cost. Special-use, gift-transfer, community-property, and consistent-reporting rules matter, and the beneficiary must maintain the basis through later improvements, depreciation, and sale. Confirm the governing rule and the estate’s actual value records before calculating the taxable disposition.
