My CPA probably has filed my many years' tax returns wrong. We just found out this year that for the investment house we have, since we have been doing married filing separate, they have for many years, used 1/4 instead of 1/2 of depreciation for both of us. This resulted in significant over-paid taxes EACH year.
My question is what is the best thing we should do given:
1. One can only amend returns for the past 2-3 years (depending on when you filed)
2 . For depreciation, this is NOT accounting change, as it is a pure simple mistake, not accounting method or other change. So a special form for depreciation change is not appropriate probably.
Thanks a lot
