Pub. 15-T describes it. Our withholding matches to the penny the amount our homegrown spreadsheet calculates using the "Percentage Method Tables for Automated Payroll Systems..." described there.I'm annoyed that I have little understanding how the payroll system figure out how much to withhold.
Anyway, has anyone managed to get something more sensible out of the withholding system?
I think the personal finance toolbox spreadsheet's W-4 section (starts in cell Calculations!F57) implements that also, with the withholding brackets shown starting in call X97 on that same sheet. I don't think that would work "as is" for you because it probably assumes 401k contributions, etc., are spread evenly through the year, but if you want to "roll your own" you might be able to use some of it as a start.
