Rental History Can Reduce the Home-Sale Tax Break, Leaving Former Landlords Owing

A retired couple selling a home with a $430,000 gain expected the $500,000 Section 121 exclusion to eliminate tax. Because the property had three years of rental use, about $30,000 of gain remained taxable, largely through depreciation recapture, creating a federal bill up to $7,500. The IRS counts depreciation that was allowed or allowable, even if the owners did not claim it.
Section 121 lets eligible sellers exclude home-sale gain if they owned and lived in the property for at least two of the five years before selling; the limit is $250,000 for single filers and $500,000 for qualifying joint filers. A carve-out denies exclusion for depreciation after May 6, 1997, and Publication 523 tells former landlords to report that portion as unrecaptured Section 1250 gain.
In the example, a couple bought for $350,000, assigned $75,000 to land, rented for three years, and sold for $750,000. Depreciation over 27.5 years produced about $30,000, leaving $430,000 gain; $400,000 was excluded and $30,000 taxable, with maximum federal tax near $7,500. Publication 544 counts permitted depreciation, not merely amounts deducted.
Former landlords and retirees selling a long-held home could be most affected, because unclaimed or forgotten depreciation may create an unexpected tax bill even when the main exclusion applies. The result may reduce proceeds and complicate retirement cash-flow planning, and it could prompt sellers with rental history to review
