Starting on my 2021 taxes, I made an error on our tax returns which affected my Biz Income that was reported. I discovered this mistake this month and realized I made the same mistake every year since. My Gross Income was over reported. I then contributed too much in my SEP for each of those years. I haven't determined how much...probably a few hundred each year.
Is it worth it to do an amended return for each of those year which would result in refunds, but would also then have a penalty from the overpayment? Thanks.
