Using RTI there is little change to the information given to your employer. To help get employee’s tax right and make sure they get credit for the NICs that they pay, they should provide:

  • National Insurance number shown on the card or letter issued by the DWP. A National Insurance number consists of two letters followed by six numbers, followed by one letter - A, B, C or D.
  • Full formal name (surname and forename) must be obtained. It is important that full forename and not just the initials (for example, John Smith and not J Smith), are provided by employees.
  • Date of birth
  • Gender

The employer needs to verify the above information from an official source, such as employee’s birth certificate, passport, driving licence or official documents from HMRC or the DWP.
