As of July 4th 2016, a new prefix ‘KC’ was brought into use for National Insurance (NI) numbers.
Unfortunately, the HMRC (Her Majesty's Revenue & Customs) systems for Real Time Information (RTI) submissions has not been not updated to accommodate this new prefix. The specifications provided to the HMRC software developers were not amended to include this in the list of valid prefixes for NI numbers.
As a result of this, any RTI submissions which include a NI number with the prefix of ‘KC’ would be rejected by the HMRC systems.
HM Revenue & Customs are aware of this and are currently working on a resolution. Please see the following update from HMRC:
Once HM Revenue & Customs (HMRC) has resolved the issue and provides further guidance, Oracle will take the appropriate action to ensure customers can process the 'KC' prefix correctly.
In the meantime, please follow the advice given by the HMRC in Pay As You Earn (PAYE): Service Availability and Issues
