LLC Taxed as S-Corp Solution
Great price and just what I needed to file my taxes as an LLC taxed as an S-Corp. I have always done all of my taxes myself, but this year as S-Corp I wanted to make sure I was organized and did everything correctly. TaxAct was a great price since all I needed to do was input the information.
