Have you ever wondered why the IRS doesn't add calculations to the pdf tax forms on their website? After all, some states such as Alabama, Ohio, and Oklahoma have done exactly that.
We don't know the answer to that question either, but we have added the calcs ourselves.
The pdf tax files on this site were downloaded from IRS.gov. Calculations were then added with javascript to make them self-calculating. Then they were posted here for your use. In most cases you only need to enter the income, deductions, and credits you are claiming and the rest of the form will automatically calculate. Since these are the same forms as on IRS.gov (except for the calculations) you can use them to file your tax return. The yellow and red information boxes that you see on the screen will not print when the forms print.
Please read the terms of use before using the forms.
To calculate the forms must you first download the pdf files to you computer and then open them with Adobe Acrobat Reader.
