Pay voluntary Class 3 National Insurance
Pay at your bank or building society
Pay at a branch by cash or cheque. You’ll need the payslip HM Revenue and Customs (HMRC) sent with your payment request.
Make your cheque payable to ‘HM Revenue and Customs only’.
Write your 18-digit reference number on the back of your cheque. You’ll find the reference number on the payslip provided by HMRC.
If you do not have an 18-digit reference number, you can:
- ask HMRC online
- phone the National Insurance enquiries line if you cannot ask HMRC online
HMRC will accept your payment on the date you make it, and not the date it reaches HMRC’s account, if you pay between Monday and Friday.
