Get your taxes done using TurboTax

Yes, many of us will. My current front runner is TaxAct.

I wonder if it will be millions. Intuit sold 5 million copies of the desktop software last year. Windows 10 is still around 40% of windows users, so that means around 2 million users are on windows 10. I bet many of those will update their PCs or be willing to use the online software. I'd guess in the 100's of thousands?
