Form 8582 When You Sell Your Rental: What Happens to Your Stuck Losses

Find it on your most recent Form 8582, Part VII, column (c). California keeps its own pile on FTB 3801, and the two often differ. Put the federal number in the calculator below.

What happens to the stuck losses, by exit

A simple example: the building is $1,000,000 above your basis and you hold $300,000 of stuck losses. $300,000 minus $1,000,000 is below zero, so $0 is allowed and all $300,000 is lost. Your children inherit the building, not your Form 8582.

The same $300,000, used in a sale against income taxed at 35%, is worth about $105,000 of federal tax.

On a sale, Form 8582 works in two steps

1. The sold building's own gain absorbs its stuck losses first. The gain is passive income, so it lets them through dollar for dollar. If the losses are bigger than the gain, the rest is freed too and can reduce any income.
2. On the tax bill, a freed loss comes off your highest-taxed income first. The gain keeps its own lower rate, 15% or 20% federal (up to 25% on the depreciation slice), while the loss is a deduction worth up to 37%. That is the rate swap.

Here is the rate swap in dollars, from the same engine that runs the calculator. A married couple with $300,000 of salary sells a rental with a $200,000 gain and holds $200,000 of stuck losses. Federal income tax is $79,468 with the losses stuck and $32,975 with them unlocked.

That is $46,493 saved. If the losses had only hit the gain, they would have saved $30,000. The gain did not become tax free. It traded places with the salary.

If your CPA grouped several rentals into one activity, selling one building may not count as selling your entire interest. Ask before you sell.

Which exit fits your losses

• Sell for cash. All the stuck losses free in year one, against gain taxed in the top brackets.
• Sell with a structured note. Each year's gain is passive income, so the sold building's own gain uses its losses first and only the leftover frees in proportion to that year's gain.
• 1031 exchange. A 1031 is not a fully taxable sale, so it frees none of them. But any boot is passive gain your stuck losses can cancel. Nobody sizes the 1031 or the Delaware statutory trust to fit your stuck losses. That is the step this page is about. Read 1031 exchange boot and suspended losses for how it works.

Frequently asked

Q: What happens to suspended passive losses on Form 8582 when I sell a rental? A: In a fully taxable sale to an unrelated buyer, they free up (§469(g)(1)(A)). The sold building's own gain absorbs them first, and any overall loss left over can reduce other income, such as your salary.

Q: Where is my suspended loss number on Form 8582? A: On your most recent Form 8582, Part VII, column (c), the carryforward into the next year. California keeps its own pile on FTB 3801.

Q: Do suspended losses free up in a 1031 exchange? A: No. A 1031 exchange is not a fully taxable disposition, so the losses stay suspended. Recognized boot gain is passive income, though, so the losses can cancel it.

Q: Do I lose my suspended losses if I hold the rental until I die? A: Mostly. They count only to the extent they exceed the step-up in basis (§469(g)(2)), which on a long-held building usually wipes them out.

Q: Do the losses come off my gain or my salary? A: On Form 8582 the building's gain absorbs them first. On the tax bill, a freed loss comes off your highest-taxed income first, so it can save more than the gain's own rate.
