As a new client of AG Tax Services, we have been delighted and very happy with the full service we have received from Michael and his team. They have identified errors and provided improvement options for our growing company, making us feel like we are finally in the right hands of competent tax accountants and an accounting firm. We've easily understood the options and corrections and appreciate the transparency as we move forward. Thank you for facilitating a smooth transition.

Michael and his team are the best in the business. I have went through 5 previous accountants that were not even close to the level of sophistication I experienced with AG Tax. The strategy we put in place is AWESOME! My taxes are way down!

I've loved the service I've received from AG Tax. I've worked with a lot of accountants over the years, and Michael is by far the best. He helped me think holistically about my business, cash flow, and taxes in a way that has unlocked a lot of financial growth for me and my business. Highly recommend. Super strategic and practical guidance.

Extremely unprofessional scammers parading as legitimate accountants.

We were referred to Michael Grossbach by our realtor. The first red flag was that his admin, Roisin pressured us heavily to put down a deposit in order to talk to Michael. Then once connected (he was very late to our meeting), it was clear that his tax philosophy was much closer to fraudulent practices skirting IRS regulations than we were comfortable with. Additionally, his suggested tax strategies were essentially debunked Reddit bro suggestions like shady life insurance policies (of course he has a buddy to recommend for commission) and buying short term rentals.

We were polite and said it wasn’t a good fit and asked for a refund of the deposit since no work had been completed. Instead Roisin and Michael decided the consult was worth $500 and no refunds were permitted. Any legitimate service provider should do a consult and a not charge if it is a good fit.

These guys are money hungry scammers who would rather have $500 than do legitimate business. Definitely avoid.
