What is a T21 file?

A T21 file is a U.S. tax return created by the 2021 version of H&R Block Tax Software, a Windows and macOS program used to prepare and file U.S. tax returns. It contains a user's 2021 tax data, including their state and federal tax forms and other information.

More Information

The 2021 version of H&R Block Tax Software (for Windows and macOS) creates and periodically saves a user's tax return progress in a T21 file. This allows users to take a break from filling out their tax return and resume their progress by loading the T21 file.

The program also creates a T21 file when users back up their tax returns for archival purposes. To create this backup, users select File → Backup Tax Return.

By default, H&R Block Tax Software 2021 saves T21 files in the following directory:

~/​Documents/​HR Block
