It's never too late. And if you hire the right one they can audit your last return to be sure it is correct. If not, they can file an amended return to pay whatever you missed before it piles up higher interest and fines or if you're lucky to factor in things you didn't know and get you a refund of part of what you paid. A good one like John can do that, and many others I'm sure.I wish i would have hire one
