How to open TT15 file?

The most common problem when using TurboTax 2015 Tax Return Format is that a specific TT15 is not associated with the program.

The first thing you should do is just "doubleclick" on the TT15 file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Programs to open TT15 file

Step 2. Create association of TurboTax with TT15 files

However, it may happen that the application itself does not cause the TT15 file to open in the TurboTax application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the TurboTax application as the default for handling the TT15 file.

Step 3. Update TurboTax to the latest version

If, despite the association of the TurboTax program with the TurboTax 2015 Tax Return Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Intuit Inc. website or update the program from the application.

Step 4. Check for the following problems with the TT15 file

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the TT15 file. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the TT15 file that we want to open. Sometimes virus-infected TT15 files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the TT15 file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular TT15 file corruption. The easiest way to restore the file is from a backup or by contacting , but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted file TT15 except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. It is best to move TT15 to a different directory.
This problem only occurs with more complex files. In this case, the TT15 file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the TT15 file while scanning. If nothing helps, please reset the device.
