We have been entrusting our returns with Flex Tax for a number of years now. They are hard working, empathic and have assisted us in maintaining compliance even when hit with several personal set backs over the years. I appreciate their patience and getting us over the finish line.

I received an IRS penalty letter related to an AMT miscalculation from ISO, showing over $250,000 in tax due plus penalties and interest. I contacted Will at Flex Tax, and he immediately stepped in with expertise and calm professionalism. Will quickly identified the issue—an ISO spread that incorrectly triggered AMT in a prior year, which the IRS had carried forward in error. He reviewed my prior returns, recalculated the AMT credit, and prepared a detailed response with supporting documents. Thanks to his work, the IRS reduced my liability by over 80% to under $50,000, and waived all penalties. The fee was very reasonable considering the savings and time he helped me recover. I highly recommend Will and Flex Tax for anyone dealing with complex equity compensation or IRS notices.

Great accountants and customer service. I really like how quick the turnaround time is. They made it easy for my bakery to deal with all the work during tax season. I have to deal with a lot so this made my life easier. Also they speak Chinese so it helps when my bakery manager talks to them.

Great service and went above and beyond. Their accounting team knows what they’re doing and are experts in their field. Even though I’m not in the same city as them, they do everything great via email. I appreciate this especially since old school spots need you to visit their office.
