So I have a few years business and personal of tax filings to catch up on. I just found out that interest paid on business purchases is deductible, even if you use a personal card. May issue is that I have been really bad about using one payment method. Is there a way to find out how much interest I have paid on specific purchases? I spent a while just maintaining high-interest debt without really making a dent. Most, but not all of the purchases are deductible in some way. Any advice?
