You only need to enrol separately for HM Revenue and Customs’ (HMRC) PAYE Online service if you didn’t get a login when you registered as an employer - this is usually because you didn’t register online.
You’ll need your PAYE reference and Accounts Office reference - these are included in the letter from HMRC confirming your registration.
After enrolling, you’ll need to activate your account.
