I've been self-employed for 15 years. Way back in the beginning my then tax guy said not to claim home office expenses because it would come off the price of my house when I sell it.Enter new tax guy today. He said, definitely take it and all related expenses - utilities, insurance, repairs and maintenance of house - in the appropriate proportion. I was told (long ago) that home office deduction is a red flag to the IRS. This guy says a Supreme Court case expanded the ability to claim home office expenses so no worries.Color me eager to get more deducted but nervous about audits.What do you think about this?
