HMRC are planning to update their systems to accept the new formats from Tuesday 15th November 2016
"From 15 November 2016 customers will be able to submit Real Time Information data for employees using this National Insurance number prefix.
Dataplan are aware of this issue and will be working with HMRC to ensure all is well when it comes to any changes.
If you/your employee has a 'KC' National Insurance number, they don't need to request a new one. Dataplan will continue to apply any tax code notices you receive from HMRC in the normal way"
So what are the changes?
The National insurance number validation will be changed to:
characters D F I Q U and V are not used as
- The letter O is not used as the second letter of a prefix
- Prefixes BG, GB, KN, NK, NT, TN and ZZ are not valid
