Open T05 File
Files with the T05 extension are a type of United States tax return file for tax year 2005.
T05 files are created with TaxCut 2005, a tax preparation program.
Tax Cut 2005
H&R Block's TaxCut 2005 software is a US federal tax preparation program that gives you the tools you need to prepare and file your 2005 federal and state tax returns.
The T05 file includes tax forms with fields that contain values filled in by the user.
Basically, the T05 file is a data file, not a multimedia or office file.
TaxCut returns can only be opened by the version of TaxCut in which the return was created, that is, in this case, with version 2005.
