What is a TAX file?

TAX is a file format used by a software tool for TAX returns called TurboTax. The TAX file is used by the Turbo Tax package to store TAX declarations of both individuals and companies. These files are stored and TAX returns for earlier periods can be accessed if needed.

TurboTax is a software released by Intuit Inc. used in the United States and Canada. In Canada, TAX files are used in the certified NETFILE format.

How to open TAX files

If you cannot open the TAX file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports TAX among those that are installed on your device.

A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the TAX file can be found in the table. Now just download and install the appropriate application.

Possible problems with the TAX format files

The inability to open and operate the TAX file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the TurboTax Tax Return Format file. Below is a list of possible problems.

  • Corruption of a TAX file which is being opened
  • Incorrect links to the TAX file in registry entries.
  • Accidental deletion of the description of the TAX from the Windows registry
  • Incomplete installation of an application that supports the TAX format
  • The TAX file which is being opened is infected with an undesirable malware.
  • The computer does not have enough hardware resources to cope with the opening of the TAX file.
  • Drivers of equipment used by the computer to open a TAX file are out of date.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the TAX file should operate with your programs without any problem. If the problem with the TAX file has not been solved, it may be due to the fact that in this case there is also another rare problem with the TAX file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?

If you want to associate a file with a new program (e.g. my-file.TAX) you have two ways to do it. The first and the easiest one is to right-click on the selected TAX file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the TAX file extension to the corresponding software in the Windows Registry.

Is there one way to open unknown files?

Many files contain only simple text data. It is possible that while opening unknown files (e.g. TAX) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
