I know someone who is a complete idiot that took the H&R test and passed. Unless your dealing with the H*R block owner who is a real tax consultant, I would rather see you attempt the schedule "C" yourself.
It's not that hard. You have to have proper records to fill it out and this is why you need to maintain the spreadsheet all year. If your spreadsheet is accurate, then you are better qualified to do your taxes than any idiot from an H&R block office.
They basically prey on low income wage earners and attempt to give them a short term loan to give them the return cash ahead of time for a loan fee. Most would qualify for free return directly from the IRS and get the return as quickly as the H&R block stealing a % of their return.
I consider the whole thing a scam. There is much fraud and the more fake dependants the merrier. The IRS allows undocumented dependants, so it means a fraudulent tax return company can defraud us real taxpayers thousands of dollars. They will "fix" the return to get the maximum "earned income tax credit"
This is basically the sweet spot of where you claim to earn the lowest amount of income and get a refund for being so poor. Each dependant makes this number higher. A common fraudulent tax preparer will make a fake company I.E. independent contractor where you made enough money to qualify for the gov't handout and not enough to pay for Obama care or any tax.
If you do enough MS, you could fall into this sweet spot if that is all you do, but doubtful if you claim mileage.
