How do I claim expenses from a previous year to offset income from rental arrears received this year?

[abletl]

My disabled daughter lives in my home and pays for room and board from SSI.  With deductions it's a wash and I don't owe any tax on it.  My issue is that her benefits were suspended for over a year due to an SSI error, and then reinstated with arrears paid from a previous year.  I understand that I have to declare the income from the arrears in the year I received them, but how can I claim expenses?  The expenses were in a previous tax year.

If you are reporting this as a rental on schedule E, you should have reported the expenses last year, 2022.

Because rental income is passive income, the loss would not have been allowed, but would be a carry-forward for 2023. 

This carry-forward loss would offset the additional income you finally received in 2023. 

If you didn't do it this way, amend 2022, claim the expenses and get the carryover loss.
