Class 4 NIC on income

To calculate this figure you will need to deduct any remaining part of the lower profit limit for the year from your net profit and then calculate the Class 4 National Insurance contributions (NIC) due.

To assist with this you can use the tax calculation tool which is available within the Campaign webpages (see below link). Alternatively, you can telephone the Campaigns Voluntary Disclosure Helpline on Tel 0300 123 1078. Lines are open Monday to Friday 8.00 am to 6.30 pm and are closed Saturday and Sunday.

If you have income to disclose from a second business you should include the liability from this business in the 'Other liabilities' box under the appropriate year. Further information about 'Other liabilities' is available within the help associated to that box.
