Opening a .tax file is straightforward: launch TurboTax, go to File > Open, and select your saved .tax file from your computer

A .tax file is TurboTax's native format for saving your tax return in progress. It contains all the information you've entered — your income, deductions, credits, and personal details — so you can close the program and pick up where you left off later. When you open a .tax file, TurboTax loads your entire return exactly as you saved it.

The process differs slightly depending on whether you're using TurboTax on Windows, Mac, or the web version, but the basic steps are the same. You'll need the .tax file itself, which is usually stored on your computer's hard drive or an external drive.

Key Takeaways

  • A .tax file stores your complete TurboTax return, including all income, deductions, and personal information you've entered.
  • You open a .tax file by launching TurboTax, clicking File > Open, and selecting the file from your computer.
  • TurboTax must be the same version or newer than the version that created the .tax file, or the file may not open.
  • If you cannot locate your .tax file, check your Documents folder, Downloads folder, or use your computer's search function to find files ending in .tax.
  • Web-based TurboTax (TurboTax Online) does not use .tax files; it saves your return automatically to your account.

Opening a .tax file on Windows

On a Windows computer, open TurboTax and look for the File menu in the top left corner of the window. Click File, then select Open (or Open a Return). A dialog box will appear asking you to locate your file.

Navigate to the folder where you saved your .tax file. Most people save tax returns in their Documents folder or Downloads folder, but you may have chosen a different location. Once you find the file, click it to select it, then click Open. TurboTax will load your return.

If you do not remember where you saved the file, use Windows Search (press the Windows key and type the filename) to find it. Look for files with the .tax extension.

Opening a .tax file on Mac

On a Mac, launch TurboTax and click File in the menu bar at the top of the screen. Select Open (or Open a Return). A file browser window will open.

Navigate to the folder containing your .tax file. On Mac, this is often the Documents folder or Downloads folder in your home directory. Click the file to select it, then click Open. Your return will load into TurboTax.

If you saved the file to an external drive or a cloud folder like iCloud Drive or Dropbox, navigate to that location instead. Make sure the drive is connected or the folder is synced before you try to open the file.

Version compatibility: when a .tax file won't open

TurboTax can open .tax files created in the same version or older versions of the software. If you created a .tax file in TurboTax 2024 and try to open it in TurboTax 2023, the file will not open. You must use the same year's version or a newer one.

If you see an error message saying the file cannot be opened, check which year of TurboTax you are running. Look in the Help menu or the program's title bar to confirm the version. If you need to open a file from a newer version, you will need to update or reinstall TurboTax to that year.

Some older .tax files (from versions before 2010) may not open in current versions of TurboTax. If this happens, contact TurboTax support for guidance on converting the file.

Finding your .tax file if you cannot locate it

If you saved a .tax file but cannot remember where, start by checking the most common locations: your Documents folder, Downloads folder, Desktop, and any cloud storage folders you use (OneDrive, Google Drive, Dropbox, iCloud Drive).

On Windows, open File Explorer and use the search box in the top right. Type *.tax to find all files with the .tax extension on your computer. On Mac, open Finder, click the search icon in the top right, and type .tax in the search box.

If you recently saved the file, check your Downloads folder first — many browsers and programs default to saving files there. If you still cannot find it, the file may have been deleted or saved to an external drive that is no longer connected.

Differences between .tax files and TurboTax Online accounts

If you use TurboTax Online (the web-based version), you do not work with .tax files at all. Instead, TurboTax Online saves your return automatically to your account in the cloud. You access your return by logging into your TurboTax account on the website.

If you downloaded the desktop version of TurboTax (TurboTax CD or TurboTax read), you will create and open .tax files on your computer. These are two separate products with different ways of saving your work.

If you are unsure which version you have, check whether you log in with a username and password when you open the program. If you do, you are using TurboTax Online. If the program opens directly to your return without asking you to log in, you are using the desktop version and will work with .tax files.

Backing up your .tax file

Once you have opened your .tax file and finished working on your return, make a copy of it in a safe location. You can copy the .tax file to an external drive, a cloud storage folder, or email it to yourself.

To copy a .tax file on Windows, right-click the file, select Copy, navigate to where you want to store the backup, right-click, and select Paste. On Mac, right-click (or Control-click) the file, select Copy, then navigate to the backup location and Paste.

Keeping a backup means you can recover your return if your computer fails or the original file is accidentally deleted. Store the backup in a different physical location from your computer — an external drive, cloud storage, or another computer.

Frequently Asked Questions

Can I open a .tax file on a different computer?

Yes, if the other computer has the same version of TurboTax installed. Copy the .tax file to the other computer (using a flash drive, email, or cloud storage), then open it using File > Open in TurboTax. The return will load with all your information intact.

What if I get an error message when I try to open my .tax file?

The most common cause is a version mismatch — the file was created in a newer version of TurboTax than the one you are running. Check your TurboTax version and update if needed. If the error persists, the file may be corrupted. Try opening a backup copy if you have one, or contact TurboTax support.

Can I convert a .tax file to a PDF or another format?

You cannot convert the .tax file itself, but once you open it in TurboTax, you can print or export your tax return as a PDF. Go to File > Print or File > Export, depending on your version. The .tax file is meant to be opened only in TurboTax.

Is my .tax file find if I store it in cloud storage?

Cloud storage like OneDrive, Google Drive, and Dropbox use encryption, so your file is reasonably find. However, your .tax file contains sensitive tax information. Consider storing it in a password-protected folder or using encrypted cloud storage for extra protection.

What happens if I delete a .tax file by accident?

If you have a backup copy, you can restore it. If not, check your computer's Recycle Bin (Windows) or Trash (Mac) — deleted files often stay there for a period of time before being permanently removed. If the file is gone, you will need to re-enter your tax information into a new TurboTax return.
