At Home 2011 tax return data

Files with the t11 file extension contain tax-return data for the 2011 tax year created by At Home software.
The files store accounting and tax information used to prepare a 2011 tax return.
File type category:
Accounting, financial and tax file
Date updated: October 16, 2026
The t11 file belongs to the 2011 version of the At Home tax-preparation application. It contains the tax-return data entered for the 2011 tax year.
At Home uses this data to prepare the completed tax-return form. The completed form can be printed or sent by email to the tax office.
The format is supported by At Home for Microsoft Windows and At Home for Mac for Apple macOS and Mac OS X. Because it is tied to the 2011 tax year, it is a legacy format rather than a current tax-return format.
Open the file with At Home 2011 on Microsoft Windows. On Apple macOS or Mac OS X, use At Home for Mac.
The file may not open correctly in unrelated tax or accounting applications because it is specific to At Home's 2011 tax-return format.
Open the file in the appropriate At Home software and print or export the completed return as a PDF for sharing. A PDF contains a view of the return and is not an editable replacement for the original t11 file.
Some data may be convertible to an exchange format for bank or accounting purposes.
