What is a .T21 file?

A .T21 file is a special type of computer file that is used for storing information about someone's taxes in the United States for the year 2021. This file is made by a program called H&R Block Tax Software, which is available for computers running Windows or macOS. People use this software to help them fill out and send their tax forms to the government. The .T21 file keeps all the important details of a person's tax return, including the forms for both state and federal taxes, and any other necessary tax information for that year.

To open a .T21 file, you need to use the H&R Block Tax Software. This is the same program that was used to create the file. It's designed to work with these specific types of files, making it easy to view and edit your tax return information if needed.
