What is a T09 file?
Tax return created using At Home 2009, an H&R Block program used to create U.S. state and federal tax returns for the 2009 tax year; includes tax forms and filled in fields by the user; may be e-filed and printed using At Home 2009.
H&R Block At Home was previously named TaxCut, which created files with the extension ".tXX", where "XX" is the two-digit tax year being filed. For example, .T08 TaxCut files are for the 2008 tax year.
