What is a TT19 file?

A TT19 file is a tax return created by the 2019 version of Intuit TurboTax Canada, an application used to file tax returns in Canada. It stores tax data, which includes Canadian federal and provincial tax information and personal data entered by the user. TT19 files are similar to .TAX2019 files created by the U.S. version of TurboTax 2019.

More Information

  • Saving a 2019 tax return to be electronically filed or printed to be mailed.
  • Backing up a tax return in case of the loss or corruption of a tax return.
