    I’ve went through many different tax site and prepares and Paramount was the most thorough, honest and considerate. They gave me a lot of helpful information and really worked with my situation to get me the best possible outcome. I appreciated their honesty and time. I hate tax season so it really helped to have nice, calm and considerate people working with me. They are also open throughout the year so that is extremely helpful! I would definitely recommend them for your tax prep
