Class 1A NIC reference checker

Step 1 - Enter your PAYE Accounts Office reference number

Step 2 - Choose the year you are paying for
Step 3 - Press the 'Check reference' button to check the format of your Accounts Office reference which will be shown in the result box below. If you need to start again, press on the 'Clear' button


Please use the reference number in the format shown, with no spaces. If you do not, your payment will take longer to reach your account.

Remember to change or remove the extra 4 numbers when no longer applicable. For example, when you pay your PAYE (not Class 1A NIC) on time all you need is your 13 character Accounts Office Reference.
