Some say the tax prep franchises aren’t exactly experts. Some say they’re more interested in repeat business and up selling other products by finding refunds to cover them - legal or not.
Most people don’t realize the tax preparer is basically liability free from the IRS perspective. You’re on the hook 100% for the accuracy when you sign them, no matter how many CPA’s and lawyers you hired to do them for you. Nearly all tax preparers, like financial auditors, have a disclaimer absolving themselves if they were provided inaccurate info (such as a form you might have signed where the $12/hr seasonal dufus marked you told them you bought the car instead of leased - so their “insurance” covers diddly squat.)
Some say I might know at least one such franchisee that paid some of her people under the table cash, made lots of bad advice (some on purpose, some incompetent), and who push auxiliary sales. Some say I might have had a derelict family member who worked at another tax prep franchise in two different states for many seasons despite being too inept to balance his own checkbook, but gave plenty of “expert” advice to happy refund recipients.
Caveat emptor
