There is only one file type that uses the .T12 extension:
At Home 2012 Tax Return
Tax return created with the 2012 version of H&R Block At Home tax preparation software; includes United States federal tax forms for the 2012 tax year; may also contain state tax forms if a state return has been selected; stores data entered by the user so the tax return can be saved and continued at a later time.
Completed tax returns can be printed and mailed or filed directly from within the software. At Home is available in Basic, Deluxe, Premium, and Premium & Business editions.
NOTE: At Home 2012 can also import data from At Home 2011 (.T11) files.
