I had done my own taxes for years and thought I was doing a great job and didn't think my return was complex enough to warrant hiring a tax expert. But I was referred to Matt and trusted him with my taxes last year and he incovered stuff that I should have been claiming and got my return down considerably from prior years. The savings he found me paid for his services many times over. He was super easy to work with and will be going back every year from now on!
