I am getting error 1046 when I send data to HMRC. What could be wrong?

This means 'Authentication Failure. The supplied user credentials failed validation for the requested service'.

The possible reasons for this error are:

  • User ID is wrong.
  • Password is wrong (Try logging in at the HMRC site).
  • You registered your HMRC account for PAYE but haven't yet received the activation PIN.
  • The PAYE Reference on the Employer Details page is wrong (Log in to the HMRC site to see what reference they hold).
  • The User ID is for a different business.
  • Government systems are too busy.
