Opening TAX files

Did your computer fail to open a TAX file? We explain what TAX files are and recommend software that we know can open or convert your TAX files.

What is a TAX file?

Files that contain the .tax file extension are most commonly used by the TurboTax tax preparation software program that is distributed by Intuit Inc.

There are a variety of TurboTax products available including the TurboTax Deluxe and the TurboTax Premier versions of the software. The tax returns that are created when a user does their taxes with these software products use the .tax file extension. Users can access their previous years' tax returns by opening these TAX files.

Some financial applications allow a user to import their tax information by importing the TAX files that have been created with these software programs.
