calculating spreadsheets available?

It would make a good title of a movie. ;-)

===============================I didn't examine [them] in detail but a google for "tax spreadsheet" produced a number of hits. Examples (seemed like there were others as well):

Thanks. I cannot say enough good things about the taxvisor Income Tax Planning Spreadsheets. I use them to get the state estimated taxes as close to the full tax amount as possible, so taxpayer don't end up paying estimated and a large "tax due" in one year, which could lead to the AMT.
