T2 File Name Extensions

Updated: 2023-06-05

What is a file name extension?

A file name extension are the letters and numbers that appear after the dot in the file name. For example .xlsx and .docx for Microsoft® Excel and Word. Windows® uses the extensions to relate a file to a particular software program, so that when you double-click on a file name, the right program opens. By default, Windows® hides these extensions from view unless you explicitly turn on the option to see them. So, it's quite possible you may never have noticed file extensions on your files.

Each TaxCycle T2 supports more than one calendar year. When creating a new T2 return, TaxCycle chooses the most recent module that supports the corporation's taxation year.

In TaxCycle T1, the file name extension matches the year of the tax return year it supports. However, TaxCycle T2 file extensions do not necessarily match the year-end of the corporate tax return. You may prepare a T2 return with a tax year-end in 2021 that has the .2022T2 file extension.

In TaxCycle T2, the file extension refers to the year that the module was released and not the taxation years it supports. You will notice that when we release at new T2 module--which usually happens in June or July each year--the file name extension will change and TaxCycle will suggest you to convert in-progress returns to the new module.

File Extensions in the Title Bar

By default, TaxCycle shows the corporation's year end date in a blue title bar at the top of the TaxCycle window when a file is open. It does not show the file name and extension. To include the file name with extension in the title bar:

  1. To open Options from the Start screen, click Options on the left side. If you have a file open, go to the File menu, then click Options.
  2. On the left, expand the Return preparation section and click on the Display page.
  3. On the right, check Show file name in window title.
  4. Click Apply or OK.
  5. When you have a return open, the file name with the extension now appears in parentheses after the details in the title bar.
