Identify the File Extension and Select the Correct Application

Checking the file properties helps reveal its true format, allowing you to manually associate it with the correct tax software.

When system software is corrupted or freshly installed, default file associations can be lost. By identifying the exact file extension, you can easily determine which application is required to open your tax records.

1
Open File Properties

Open File Explorer, navigate to your external drive, and locate the tax return item. Right-click the file and select "Properties" from the context menu.

2
Check File Type

In the General tab, look at the "Type of file" field to find its extension (for example, .tax2022 or .pdf). This indicates what software is required to read the data.

3
Choose Another App

If you have the correct software installed, right-click the file again, hover over "Open with", and select "Choose another app". Select the appropriate tax software and check the box that says "Always use this app to open files".

Identify the File Extension and Select the Correct Application
Missing Software: If you do not have the corresponding tax software installed on your new Windows 11 setup, you will need to download and install it before you can open the native tax data file.

Frequently Asked Questions

Why does Windows 11 ask me how I want to open this file?

This prompt appears when Windows encounters a file format it does not recognize, when your default app settings have been reset, or if the software originally used to open the file has been uninstalled or corrupted.

How can I change default apps in Windows 11?

Open Windows Settings, go to Apps, and click on 'Default apps'. From there, you can search for a specific file extension (like .pdf or .xlsx) and choose which program should open it automatically.

Can I open a tax return file in Microsoft Word or Notepad?

No, opening a native tax data file (like .tax or .t22) in text editors like Word or Notepad will display unreadable gibberish. You must use the specific tax software it was created in, unless the document was explicitly exported as a standard PDF.
