This is happening again as of Jan  31, 2026.

FAILED_VALIDATION: Error Code 54

This version of TurboTax is no longer current. You must ... blah blah Check for Updates and then you can e-file. 

Can not

If you can’t update your Windows program try doing a Manually update.  Don't know if it's only for personal programs or for Business too.

I just got the same error in TT Business.  I downloaded and installed the manual patch and got the same error again.

Same problem in TTax Business 2025:  Failed Validation Error 54.

- Checked for updates, none needed.

- Restarted computer, same error.

- Uninstalled and reinstalled TTax, same error.

Ridiculous that this same problem is happening this year.  Intuit / TTax could at least tell us what's going on, and whether we need to wait for an update.  Some of us would like to finish our taxes asap instead of waiting for the last minute.
