Do I have to amend the following few years tax returns for an increase in the form 8582 loss from a few years back? Or can I just update the next year 8582 available loss with change from a few years back?
I had schedule E rental losses in all years from 2020 to 2023. I filed my taxes for all of those years. Now I am noting that I had a bigger loss in 2021 and need to increase the carry forward losses to roll to 2023 or 2024 directly. This will give me a larger form 8582 loss in 2024 but will not change any other calculation or tax liability in the years 2020 to 2023. Do I have to amend the full 2021, 2022 and 2023 tax returns to benefit for this increase in 8582 loss from 2021? Or can I just amend 2021 and its form 8582 and just change the beginning carry over loss in 2024? Do I have to amend 2022 and 2023 tax return in order to increase form 8582 loss carry forward?
