At the closing of the sale of their house today, each of my parents was given a form to fill out to determine whether the sale needed to be reported to the IRS. They were the normal questions (lived there 2 out of 5 years?, etc.), but they came to one that asked about business use of the home since 1997. My father used part of the basement in his freelance art business starting several years prior to 1997 until
1999, so we had to mark that box Yes. That led the closing agent to retrieve those forms and fill in another one to report the sale.My father said he did take deductions for the basement office for the years he freelanced. I skimmed Publication 523 to determine what he needs to do, but I have questions:
1) I unserstand that he has to report the previous years' deduction amounts on Schedule D and pay Capital Gains tax on them, correct?2) Does he have to go back to the first year he claimed the deduction, or only to 1997, which was the focus year of the form they started to fill out?
