But eating while traveling is much more expensive than eating while at home. Travel meals are deductible according to my CPA (and quickbooks has a "travel meals" category).Travel, secondary housing, etc is ok for interviews. Food can be, but it's iffy. If you're feeding someone else then it's entertaining expenses. If you're just eating, then no. Everybody eats, regardless of whether they're interviewing or not.
Give me a break. This stuff isn't that bad. The IRS publishes publications that explain all these rules. Sometimes there is a judgement call, but as long as you're reasonable at worst you'll have to pay that back in an audit with penalties and interest. Try these IRS resources that answer all your questions. You'll probably learn something else useful while you're in there.Unfortunately the tax laws are so complicated that what is/is not deductible is realistically only determined when you are audited.
