Exclusion of capital gains from house sale with carryover losses

[zoneman2018]

Sold a house last year and have capital gains.  I know I am eligible for the $250K/$500K exclusion, however I also have a carryover loss from the sale of another house the previous year.  Do I have to use that loss to offset the gain this year, or can I use the exclusion on the gain and continue to carry over the loss to this year, and beyond ?

@zoneman2018 more detail required on the first home transaction.

selling your primary home at a loss is a personal loss and not deductible anywhere.  Say more about the home sold at a loss. Your personal home, a vacation home, investment property, etc.

not tracking how you could have a carryover loss on a prior home sale.  Again, more detail required.

Ah, sorry, I see where it makes a difference, NCperson.

The property sold in 2024 was not for personal use (never lived there, not a vacation home or rental).  Treated it like an investment.  The house sold in 2025 was my personal home.

@zoneman2018 so if that first home was never a rental and not your primary home, it was a 2nd home.  The loss on that home is a personal loss and not tax-deductible.  If you reported it on form 1099-B, suggest going back and amending.  

You can't treat things "like" an investment.  There are certain rules and regulations that govern what an investment is.  And a home that is not rented out is a personal asset and not an invested asset, so it is not an investment. 

You do not have carry-over losses. 

For the home sold in 2025, as long as it was your primary home and you owned and lived in it for 2 of the last 5 years, then you are eligible for the exclusion of $250,000 (or $500,000 if filing JOINT)

So besides Form 8949 and Schedule D, what other proof would be needed to show it was an Investment Property?  Perhaps your answer would depend on how the property was acquired?  It was inherited.  So what part of the following statement is not true ---

Regarding capital gains on inherited property (and losses), you can claim a capital loss on inherited property if you sold it and all of these are true:

   You sold the house in an arm’s length transaction.
   You sold the house to an unrelated person.
   You and your siblings didn’t use the property for personal purposes.
   You and your siblings didn’t intend to convert the property to personal use before the sale.
An arm’s length transaction is a transaction where the buyers and sellers have no relationship to each other. Except when handling an inheritance, related parties include:

   The estate
   The executor
   Beneficiaries of the estate
Report the sale on Form 8949, which will transfer to Schedule D. Enter your basis in the property as your share of the fair market value (FMV) of the property on your mother’s date of death.

 @zoneman2018 when I asked for the backstory, you didn't indicate that you inherited the property!  BIG missing detail.   Under the assumption that your intent was to sell this property faily quickly after you inherited it, then the losses are deductible.  

back to your original question: 

<<Do I have to use that loss to offset the gain this year, or can I use the exclusion on the gain and continue to carry over the loss to this year, and beyond ?>>

the loss reported when you sold the property in 2024 can be netted against any capital gains you have into the future, and if you don't have any gains to let that loss against, up to $3,000 of the losses can be used each year until consumed to reduce your ordinary income.

you use the exclusion on the gain and then continue to carry over the loss to this year and beyond.
