Debt Management and Banking Manual

Debt and return pursuit: miscellaneous charges: Class 1A NICs - penalty determinations for late return of form P11D(b)

Class 1A NICs penalties are imposed under Regulation 81(2) Social Security (Contributions) Regulations 2001 where the employer does not provide a return by 6 July each year. R81(2) is in two parts, each imposing different penalties which may be appealed against and are due and payable 30 days after issue of the notice imposing the penalty. Penalties are imposed only on P, P(SC) and Taxed Award Scheme employers.

Penalties under R81(2)(a)

The penalties under R81(2)(a) are imposed automatically using the Employer Compliance System (ECS). Penalties are imposed for the number of months the failure to provide a return continues, up to a maximum of 12 months.

Penalties are charged at £100 per month or part-month for every 50 employees. The R81(2)(a) penalties cannot exceed the amount of Class 1A contributions due for the year and where the amount of the penalty is less than £100, as a result of this cap, it will not be charged.

“Interim” penalties where the return is outstanding will be issued in bulk at 4-monthly intervals, in November, March and July each year. “Final“ penalties, where the return has been submitted, will be issued on a daily basis as returns are received and captured.

Penalties under R81(2)(b)

Penalties under R81(2)(b) are imposed after the failure has exceeded 12 months from the due date.

Recovery action

SAFE will make initial applications for payment. If unpaid, the charge will be passed automatically to IDMS and follow the existing IDMS rules to decide the next action and as appropriate the enforcement path.


The work item will appear on the C/W MISC Worklist and is distinguished from EOY penalties by the letter ‘B’ in the interest indicator field.

Class 1A NICs penalties are recoverable as if they were Class 1A contributions due from the employer. You may therefore take any of the normal methods of enforcement proceedings to recover Class 1A NICs penalties. If you take proceedings for both tax and NIC Class 1A penalties in the same action, show them separately as ‘tax’ and ‘Class 1A NICs’ penalties.
