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
- The government gateway is too busy
