NIM24131 - Class 4 NICs: Structure: Annual Class 4 NICs maximum pre 6 April 2003: Contributors who are employed and self-employed: Examples: Profits exceed the Upper Profits Limit but maximum Class 1 NICs paid
Regulation 100 - Social Security Contributions Regulations 2001
NIM24125 provides guidance on the calculation method used to determine the Class 1,2 and 4 NICs annual maximum liability for a contributor who is both employed and self-employed during the same tax year.
The following example illustrates the calculation for a contributor whose profits for the tax year exceed the Upper Profits Limit and who has also paid the maximum amount of Class1 and 2 NICs payable.
The calculation method shown applies only to tax years up to and including the 2002/2003 tax year. For guidance on the Class 1, 2 and 4 NICs annual maximum for tax years from 2003/2004 see NIM24150 onwards.
The example uses the rates and limits in force during the 2002/2003 tax year.
Mr Parker has been self-employed for the whole of the 2002/2003 tax year. His profits from self- employment for the year amount to £60,000. Mr Parker was also employed during the 2002/2003 tax year and has paid the maximum amount of Class 1 NICs due. The total amount of Class 1 and 2 NICs paid by Mr Parker is £2628.80
Step 1
Calculate the Class 2 and 4 maximum for the tax year.
Class 4 = £30,420 (UPL) - £4.615 (LPL) x 7% | = £1,806.35 |
---|---|
Class 2 = £2.00 x 53 | = £106.00 |
Class 2 + 4 maximum | = £1,912.35 |
Step 2
Deduct from step 1 the amount of Class 1 and 2 NICs paid
£1,912.35 - £2,628.80 = minus £716.45
Step 3
If the result of step 2 is a negative figure, no Class 4 NICs are due
If the result of step 2 is a positive figure, that is the maximum amount of Class 4 NICs due
As the figure at step 2 is a negative figure, Mr Parker is not liable to pay any Class 4NICs.
