Error 1046: Authentication Failure is the most common issue when trying to submit your Real Time Information to HMRC

Error 1046, one of the most common issues that you may face when processing payroll. The Error 1046 will state: The supplied user credentials failed validation for the requested service.

BrightPay does not check your User/Sender ID and Password as we don’t know what they should be. BrightPay sends this information to the Government Gateway. If you get this Error 1046 it means that the Government Gateway has rejected the submission.

Is the User/Sender ID and Password correct?

Ensure that you can access the HMRC website at using your User ID and Password that you entered in BrightPay. If you are unable to log in you can call the HMRC Online Services Helpdesk on 0300 200 3600.

Is your password greater than 12 digits?

When you are entering your password into the HMRC website, only the first 12 digits will be accepted. However when entering your password into the software it recognises all digits and deems anything after the first 12 as being incorrect causing the Error 1046. If your password is longer than 12 digits, only use the first 12 in BrightPay.

Is your Government Gateway activated?

Once you have registered to use HMRC’s Government Gateway your new Activation Code will be sent via post within 7 days. Once received you can log into HMRC online using your User ID and Password and activate the service. You must do this within 28 days of the date shown on the Activation Code letter.

Double check the information you entered in BrightPay!

Ensure that your PAYE reference number, Accounts office reference and HMRC office name are entered correctly and match the details that HMRC have for you. Check the references don’t have 'Z' instead of '2' or '0' in place of 'O'. Ensure your email address is correct and matches the one you have registered with HMRC.
