I used Revenue Canada's instructions for computer programs to create a spreadsheet that I called "payswell". I GPLed it and published it at sourceforge however I only implemented one tax year.

In the US every state has different income taxes; some don't have income tax at all such as Washington. I always intended to create a US spreadsheet but the task seems daunting.
