Pay voluntary Class 3 National Insurance
Pay online using your 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 on your HM Revenue and Customs (HMRC) payment request
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
Your payment may be delayed if you use the wrong reference number.
The payment is usually instant but can take up to 2 hours to show in your bank account.
If 5 April falls on a weekend or bank holiday, make sure your payment reaches HMRC on the last working day before it.
