Get your taxes done using TurboTax

Yes, it's simple to multiply the numbers. The issue is that the pre-filled 45% in colume (b) and 67.5% in column (c) are too high unless I am missing where those numbers came from. Since they are too high, the schedule calculates quarterly payments for quarters 2 and 3 (columns (b) and (c)) that are too high. So you owe a penalty that you shouldn't actually owe. I don't like to pay penalties, especially ones I shouldn't actually owe.
