TT18 File – What is .tt18 file and how to open it?

Definition and Purpose of TT18 Files

A TT18 file is specifically associated with TurboTax Canada, a tax preparation software application. The file extension .TT18 denotes a tax return file created using TurboTax Canada 2018. It contains all the necessary financial and personal information required to file taxes with the Canada Revenue Agency (CRA). Upon completion of the tax return within the TurboTax application, it is saved as a TT18 file.

Structure and Compatibility

TT18 files are structured to adhere to the Canadian tax filing requirements set forth by the CRA. They store data in a proprietary format that is compatible solely with TurboTax Canada 2018 software. This ensures that the information is accurately parsed and formatted when submitting the tax return electronically or by mail. However, it also means that TT18 files cannot be opened or processed by other tax preparation software or third-party applications.

Alternative Methods for Opening TT18 Files

If you do not have TurboTax Canada 2018 installed or cannot access the software, there are limited alternative methods for opening TT18 files:

2. File Conversion Services: Some online services offer file conversion capabilities, including the ability to convert TT18 files to other formats. However, these services may come with limitations or compatibility issues, and the accuracy of the converted data is not guaranteed.
