Reminds me of a little story from when I first started out in public accounting. We had hired a retired IRS agent that really wasn't ready to retire completely so he worked part time for us. He said that he would always get the "I know someone who is deducting that" when he would come up with some audit changes during his IRS days. He would respond by grabbing a clean tablet of paper and a pen and then would politely ask them for the names of those "someones". To the best of my knowledge he never got a name in all of his years doing that. So my advice is, next time someone tells you that, ask them to provide names because you know people at the IRS that would like to talk to them
