Can I deduct the portion of the room and board that was paid for by the 529 plan?

Q. Can I deduct the portion of the room and board (R&B) that was paid for by the 529 plan?

A. No.  You could deduct any R&B even if it was not paid for by the 529 plan.  R&B is not a qualified expenses for a tuition/education credit. 

R&B is a qualified expense and can be counted when determining if any of  the 529 distribution is taxable. 

If you are referring to adding the cost of room and board to your Qualified Educational Expense, for your 529 Plan distribution,  then yes, you can.  

Form 1099-Q doesn't need to be reported on your tax return as long as the distribution was used for qualifying expenses, which includes books, tuition, mandatory fees, room and board, and any necessary equipment.

TurboTax will help you determine taxability and only report any taxable income.

1. Open or continue your return.

3. Scroll down to the Education section under All tax breaks.
