"Amazing experience with this firm! The most challenging part for my taxes is figuring out how to get the most deductions being that I often have more than one W-2. I usually also have some equity (RSU and ISO) which can get pretty confusing. They have been my go to firm for taxes for three years now. Thank you for the great work!" -Timar Smith, Google Review
