Pay voluntary Class 3 National Insurance
Approve a payment through your online bank account
You can pay voluntary Class 3 National Insurance directly using your online or mobile bank account.
You’ll need:
- your online banking details
- the 18-digit reference number shown on your HM Revenue & Customs (HMRC) payment request
If you do not have an 18-digit reference number you can get help from the National Insurance Helpline.
Your payment may be delayed if you use the wrong reference number.
When you’re ready to pay:
-
Select the ‘pay by bank account’ option.
-
You’ll then be directed to sign in to your online or mobile banking account to approve your Class 3 National Insurance payment.
The payment is usually instant but sometimes it takes up to 2 hours to show in your account.
