Can I use my long-term capital loss that I have from my single returns in 2023 on my joint return in 2024? I got married in 2024.

If you have a capital loss carryover from tax year 2023 then you are required to enter carryover on the 2024 tax return.  Your filing status does not effect how to report the carryover.

Yes, as DoninGA said, you can use the capital loss carryover from your 2023 single return on your 2024 joint return. But you have to use the correct carryover amounts. In your other question you said that you omitted the loss from your 2021 return, so it did not carry over to 2022 and 2023. You absolutely must recalculate the 2021, 2022, and 2023 tax returns so that you have the correct amounts on your 2023 return to carry over to 2024.

Please do not post any more separate questions about your capital loss carryover. When information is scattered in multiple threads it's confusing and hard to follow, and hard to see the whole picture. Please keep all your related questions in one thread. If you have further questions about your capital loss carryover, post a reply in this thread. Do not post another separate question.
