Forms P11D, P9D and P11D(b) must reach HMRC by 6th July following the end of the tax year. You must also provide a copy of the P11D or P9D to the relevant employee by this date.
Your payment of the Class 1A NICs declared on form P11D(b) must reach HMRC by 22nd July, or by 19th July if you pay by cheque.
This doesn’t apply in your case, but if you had indicated that P11Ds were due on your final payroll submission, and then in the end they were not required, you must still take action. You should inform HMRC they are not due using the online form 'No Return of Class 1A National Insurance contributions'. If you do nothing, HMRC may issue you with P11D late filing penalties.
If you would like any assistance in preparing your P11Ds, P9Ds or P11D(b), please contact us to be put in touch with your local TaxAssist Accountant who would be happy to help.
