What Happens to Suspended Rental Losses at Death?

A decedent's suspended passive losses from a rental may become deductible on the final return only to the extent they exceed the increase in basis the heir receives. The losses do not simply move to the heir's tax return.

Why death differs from a taxable sale

Rental losses can be suspended under the passive-activity rules for years when the owner lacks sufficient passive income or a qualifying exception. A fully taxable sale to an unrelated party has one release rule. Transfer at death has a different rule: the decedent's unused passive losses from the activity are allowed on the final return only to the extent they exceed the basis increase in the property transferred at death.

This rule prevents a double benefit where an heir takes a higher tax basis and the decedent also deducts all previously suspended losses. It is not a statement that every inherited property receives a full basis step-up; ownership structure, estate valuation, and other basis rules have to be established first. The estate and income tax workpapers should be reconciled rather than prepared independently.

Illustrative calculation

Suppose the owner has $90,000 of suspended passive rental losses attributable to a property, and the basis increase at death for that property is $65,000. In a simplified example, $25,000 may be allowed on the decedent's final return under this special rule; $65,000 is not carried to the heir. If the basis increase were $100,000, these particular suspended losses would not produce a final-return deduction through the death rule. Other passive activities and limits still require separate review.

Trace losses by activity and owner

Do not use a single portfolio loss total. Identify the relevant rental activity, any valid grouping elections, ownership percentage, prior-year Form 8582 carryforwards, and basis/at-risk limits. A passive loss that never passed the basis or at-risk limitation is not necessarily in the same category as a loss suspended solely under Section 469. Joint ownership, partnerships, and S corporations add pass-through schedules that need to be matched to the decedent's records.

Coordinate the final return and heir basis

Collect the decedent's depreciation schedules, prior Forms 8582, K-1s if relevant, deed and entity documents, date-of-death valuation, and estate tax filings. Determine the basis immediately before death and the heir's basis under the applicable rules. Show the basis increase and released loss calculation in a memo attached to the final-return file. An heir should separately establish their own depreciation starting point if the inherited property is held for rent.

Pay special attention to pass-through ownership

If a partnership owns the rental, the decedent transfers a partnership interest, not a direct deed in the building. Outside basis, inside basis, any Section 754 election, and the value of the inherited interest can affect the analysis. The partnership's final K-1 for the decedent and the successor's first K-1 should be coordinated. An inherited interest with debt allocations requires particular care because liabilities can change partner basis without changing property value in the same way.

For direct ownership, a valuation dated near death and a complete depreciation history help establish both the basis increase and the final-return loss release. The preparer should preserve a schedule showing which suspended losses were used against passive income before applying the death rule. If several rentals were grouped as one activity under a valid election, retain the original election and consistently apply that activity definition. Without that history, the final-return deduction can be overstated or missed.
