much more comprehensive. It is based on this guide https://www.irs.gov/pub/irs-pdf/p15.pdf which is fairly complicated. It all varies based on how often you get paid, whether you're married filing jointly, etc. I didn't put in all those different cases into my spreadsheet. So it's really only useful for someone who is married filing jointly that gets paid every week and makes roughly the same amount I do. I didn't program in the entire tax table. Which means I have to update my calculations if I ever move up into the next bracket in the table.

You can fill out this form accurately at any point during the year and it will tell you what your tax liability will be and what to set your withholdings to in order to get there.



I can definitely sanitize my spreadsheet and post it, but it would probably take longer to figure out how mine is setup than to just create one for yourself using the guide and the calculator.
