Notes about the T05 file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The T05 file type is primarily associated with 'TaxCut' by H&R Block e-solutions. TaxCut is software to prepare US federal and state income tax forms.
