CDTFA Offer & Compromise

Hiring Bill from a google search was the best thing that ever happened to me. My business owed over $250,000 to the CDTFA. I was hoping that Bill firm could help me reach a manageable payment plan. In the end, Bill & Dan were able to negotiate an offer and compromise for a fraction of what was owned,... allow me to resolve a problem that I though would never go away. The entire staff was fantastic. I would recommend Bill Hartsock to anyone seeking a competent knowledgeable and professional tax attorney. Thank you for me there for me.

Bill and his team are the best

Bill Hartsock and his team provided me the most professional, knowledgeable, aggressive and fair representation I could have ever asked for. Bill and his team are straight up and know tax law. This was most important to me, as the team helped me understand that although they couldn’t make my tax prob...lem go away, they could and did minimize to the fullest and fairest extent my tax liability exposure. I would definitely go to Bill and his team again. They are simply the best in their field

Aggressively making happy customers

I am most impressed by Bill's relentless drive to make happy customers and he is aggressive. He tends to understate what he can deliver, so I checked with him frequently in the initial a couple of months. After he won the first round with IRS perfectly, I was really impressed, but felt that we were p...robably a little bit lucky. Quickly, he won the second round, again perfectly. Then I just forgot about my IRS audit all together: I did not contact him and did not even think about it at all, just waiting to receive monthly bill from him and pay it, I was 100% assured that my case was in capable hands. I slipped so far on this slope that I even forgot to return his call on monthly status update. Why should I care? Bill is handling it! Then all of a sudden, my audit is over: I owe IRS not a penny. By the way, his staff, Sherry and Thida, in particular, are nice and caring. After I handed them a tone of my tax documents, I was expecting that Sherry would sit down with me to decipher them, but she did it without a single question.

Miracle Worker

We had the worst of the stereotypical auditors. We'd been dealing with her for three years until the firm with whom we had been dealing missed an appointment. They told us it was all over, we would have to pay $30K+. Bill Hartsock got us a new appointment with a new auditor After Bill met with the...m, we owed the IRS NOTHING!!
