Renting out rooms in my home, what's the proper way to deal with utilities for tax purposes?
It's the same result either way.  Say the bills are $600, and you are reimbursed $400. You'd be able to write off $400 as part of the utilities that are common expenses, but then claim the $400 as income.  I'd stick with that, and have contemporaneous records supporting all cash flow. You also can take 2/3 of any other maintenance costs that most homeowners can't. Like snow removal, lawn care, etc.
