Sale of Principal Residence / §121 Planning: The Home-Sale Exclusion Is Simple Until It Isn’t
Home sale planning can require ownership and use tests, partial exclusions, basis reconstruction, depreciation, nonqualified use, divorce, death, rental conversion, §1031 interaction, and state deferred-gain tracking.
The §121 home-sale exclusion is familiar, but mixed use, nonqualified use, depreciation, prior exchanges, divorce, trusts and partial exclusions can make a residence sale substantially more complex than the headline exclusion amount suggests.
Verify ownership and use periods
The practitioner should establish the exact acquisition date, periods of principal-residence use, absences and prior §121 exclusions. Married taxpayers can have different ownership/use histories.
Nonqualified use can allocate gain
Periods of nonqualified use after 2008 can make part of the gain ineligible for exclusion, subject to statutory exceptions. Chronology matters; later residence use does not erase all earlier nonresidence periods.
Depreciation is not excludable
Gain attributable to depreciation allowed or allowable for post-1997 business or rental use generally cannot be excluded. Preserve home-office and rental depreciation records.
A prior §1031 exchange changes the analysis
Property converted from rental/investment use to a principal residence can be subject to both §1031 holding rules and §121 nonqualified-use limitations. Track the exchange basis and deferred gain.
Life events can create partial exclusions or legal issues
Employment, health and unforeseen-circumstance exceptions may permit a reduced exclusion. Divorce, trust ownership and death can alter ownership/use/basis and require legal-document review.
Planning takeaway
The home-sale exclusion is simple until the property’s history is not.
Build a property chronology, reconcile depreciation and prior exchanges, and preserve acquisition/improvement records until the final tax consequences are settled.
