If the above error message appears on the FPS exception report, it is because the employee's National Insurance (NI) letter is incorrectly set to B, E, I, or T. According to HMRC guidelines, these letters are not valid for employees born after 5 April 1961.
To remove this error message, the support team will need to run a background update. After the team has made the update, you'll need to regenerate the FPS file and submit it.
To do this, follow the steps below.
Log a support case: Raise a new case online and reference this article. Attach the FPS exceptions report for review.
NI letter update: Confirm the correct NI letter. Support will investigate and update the NI letter on the locked tables to the proper classification for that period.
Regenerate and submit FPS: Once Support confirms the NI letter has been corrected, regenerate the FPS and resubmit it.
Pay adjustment (If Required): The NI letter change will not automatically recalculate employee pay.
If pay needs to be adjusted based on the correct NI letter:
Submit the corrected FPS first.
Process a cancel payment and a manual payment using the updated NI classification.
Any pay difference will be reflected in the next FPS submission for the pay group.
