reporter: he paid deutch s firm a fee of $2,900 and they arranged a payment plan with the irs. $905 a month but upset with those terms, he then called the irs himself. to my surprise, it took less than half an hour to set up a payment plan that was actually $200 a month less than what the roni deutch firm set up. reporter: but deutch told us what mr. thomas accomplished is rare. he does not reflect what it is like for the average taxpayer who owes the irs and attempts to negotiate on their own behalf. but deutch s firm is being sued by california s attorney general for making exaggerated claims. she calls it election year politics but her firm is not the only one being investigated. we ll solve your tax problems. world news also reported here on tax masters, under investigation for deceptive practices in at least two states. when you call, you think you re talking to a tax professional. you re really talking to just a salesperson who is trying to get you to sign up. r
