EDIT: I'm not a tax person, obviously people aren't being illegal and dishonest. It's just smart to write off everything possible in a founder's life as a business expense. Maybe housing or this or that doesn't qualify where you live? Great that's what the minimal salary is for. Everything else goes on the company card.
2nd EDIT: I don't really understand why everyone is so cagey whenever this topic comes up. This isn't news. The IRS isn't reading this saying "gosh darn they figured out a new loophole". The laws are clearly spelled out, it's up to you to apply them to your situation. Remember, tax evasion is illegal. But minimizing tax liability is 100% okay and literally the name of the game. Otherwise, we wouldn't have tax breaks in the first place.
