.T01 File Extension
What is a T01 file?
A T01 file is a tax return created by H&R Block TaxCut 2001, a discontinued U.S. federal and state tax preparation program. It contains fillable tax forms and information a user entered on those forms for the 2001 tax year.
H&R Block developed desktop TaxCut software for Windows and macOS to allow users to more easily prepare their tax returns from home. TaxCut was available throughout most of the 2000s until H&R Block replaced it with H&R Block At Home for the 2009 tax year. H&R Block then rebranded At Home software as Tax Software.
How to open a T01 file
You can open a T01 file with H&R Block TaxCut 2001 and later versions of TaxCut. However, recent versions of H&R Block software do not support T01 files.
