Really?

I heard a commercial on the radio this morning about tax relief. The part that stuck out to me went something like this: "thousands of honest, hard-working Americans have used [insert service name] to take care of their tax problems." Something seems wrong to me. If you were an honest American, would you really have tax problems big enough to need a third-party? Just asking. Maybe someone who knows more about the IRS can see how this is possible, but it seems dodgy to me.
