My taxes are complicated and I've always paid a CPA. I'm planning to try Turbo Tax this year but want assurance that I can get a refund if I end up having to use a CPA.

My taxes are extremely complicated and I'm tired of paying someone $600 to do them for me. I own my own business, and file in 2 states. I'm concerned that even after paying for Turbo tax I'll still end up having to use a CPA. I want assurance that I can get a refund from TT if I cannot use their services.
