You're here because you have a file that has a file extension ending in .tax. Files with the file extension .tax can only be launched by certain applications. It's possible that .tax files are data files rather than documents or media, which means they're not meant to be viewed at all.

The TAX file type is used by TurboTax, a tax-filing software created by Intuit Inc. The software is solely used for the creation of US-based tax returns and cannot be used internationally. There are Windows and Mac versions available. It can be used for both federal and state income tax returns. The resulting forms are subsequently validated and prepared for submission either online or via post. Previously this software was developed by Chipsoft until they later sold it to Intuit. The software uses a simple step-by-step methodology that means even people not familiar with tax returns can easily complete their individual or small business tax returns using the software. It is also fully supported and the developers are happy to answer general tax related questions in addition to those pertaining to the usage of their software The file extension is often prep ended with a year - for example “.tax08” or the more common “.tax2008” for tax returns in the year 2008.

Launch a .tax file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .tax file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .tax files aren't yet associated with it. In this case, when you try to open a .tax file, you can tell Windows which application is the correct one for that file. From then on, opening a  .tax file will open the correct application.

Be careful not to rename the extension on .tax files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

A file extension is the set of three or four characters at the end of a filename; in this case, .tax. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
