Example: How Mei works out her Class 4 National Insurance contributions

Mei is a self-employed landscape gardener. In order to work out how much Class 4 National Insurance she is due to pay for the tax year 2015/16 she needs to know three things:

  • Her taxable profit: £27,000
  • The Class 4 National Insurance thresholds: (see above)
  • The Class 4 National Insurance rate her profit is subject to: 9%

As Mei’s taxable profit is over £8,060 but under £43,000, she is due to pay Class 4 contributions. She works how much is subject to Class 4 deductions:

£27,000 - £8,060 = £18,940 subject to Class 4 National Insurance

Mei then calculates how much she is due to pay:

£18,940 x 9% = £1,704.60 to pay in Class 4 National Insurance contributions

As Mei completes an annual Self Assessment tax return through FreeAgent, this is automatically calculated annually as part of her overall tax bill.
