FPS not subitting. It says it cannot my hmrc login or password is incorrect when they arent

Hey there, Louise68.

A common cause of rejection when submitting an FPS is the Government Gateway credentials entered. It's either not activated yet, or it was entered incorrectly.

To activate your credentials, see this article for steps: Turn on RTI reporting to HMRC in QuickBooks Online Standard Payroll. Once done, follow these steps to check if the entered credentials are correct:

1. Go to the Gear icon. 
2. Select Account and Settings.
3. Hit the Payroll tab.
4. Search for the Online filing with HMRC section, then click it. 
5. Check if the entered credentials are correct. Make changes to it if necessary. 
6. When finished, press Save, then Done.

After that, go back to submitting your FPS in QuickBooks Online. However, if you're still getting the same issue, I'd suggest logging into the HMRC Online Services and reset your password from there or give them a call for further investigation.
