14.1 National Insurance numbers

So that we can make sure that your employee's National Insurance contributions can be set against the right person's record, you must include the employee's correct National Insurance number (NINO) on any forms that ask you for it. Leaving it off can cause problems and delays.
We have to find out the missing NINO and will probably need to contact you before National Insurance contributions can be allocated to the employee's account. In the meantime, this may cause a delay in working out and paying that person's benefit (including their state pension).
