The banks are the paying client. They have reason to be concerned that eyes are dotted and tees are crossed, or they would not be shopping tax prep franchises. RALs are under fire because of their very steep interest charges among other things, which can be as much as 1000%. Not all RALs, this year, will result in a credit check, they're random, due to pressure by the IRS. The banks are at risk that this business will become a thing of the past.
But there are two different things going on here. The bank business-RALs, and tax preparation. The shops don't address the competency of the tax preparation. You're on your own there; fallout belongs solely to the shopper.
It's true that some tax prep offices are pitifully trained. I would dread the thought of going through the process of finding someone competent and knowledgeable among the major players - HRB, Liberty, Jackson-Hewitt. It would take legwork and research. There are experienced, conscientious prep offices. Ask questions - what's their retention rate, do they guarantee accuracy, how long have the preparers worked there, do they train/certify annually. When you find an office who gives the right answers to those questions, then test them further with questions specific to your situation.
I remain of the opinion that these are shops to be avoided. Too much to risk, which could result in years of grief and aggravation.
