Beats the hell out of me. Why not simplify the tax code so no one needs a tax preparer?
It might have something to do with creating chaos and confusion. (In addition to reasons mentioned in post 6 and 7).

Generally, the IRS does not contact taxpayers by phone. But legitimate bill collectors and tax scammers do. Once the private collection program begins, which Congress says should be early next year, it will be even more difficult to distinguish between the real and fake bill collectors.
This is the correct question.
