07 October 2016

7 October 2016

The technical specifications for RTI 2017-18 on GOV.UK have been updated and the latest version allows for National Insurance numbers (NINO) with a larger range of 2-letter prefixes (including KC) to be submitted.

The LTS and TPVS/VSIPS test services are now available for 2017-18, with a further update planned for late November to cover the above NINO changes. The DPS test service for 2017-18 is also available now.

National Insurance numbers with ‘KC’ prefix

As a reminder, if you do receive a KC prefix NINO HMRC has advised the following:

In July we told you that a small number of our customers were not able to submit Real Time Information (RTI) data for employees with National Insurance numbers with prefix ‘KC’.

From 15 November 2016 customers will be able to submit RTI data for employees using this National Insurance number prefix.

Some software products, including HMRC’s Basic PAYE Tools, may not be updated before April 2017. If this applies to you then you should continue to follow this guidance when submitting your RTI:

  • the National Insurance number field should be left blank
  • you should make sure the employee address field is completed in those cases.

If you/your employee has a ‘KC’ National Insurance number, there is no need to request a new one.

You should continue to apply tax codes and notices you receive from us in the normal way.
