Class 1 Structural Overview from 6 April 2003: Structural changes: The Class 1 and 2 annual maximum: Employees in contracted-out employment
Regulation 21(3), SS(C)R 2001
NIM01163 explains the calculation of the Class 1 and 2 annual maximum for employeeswho have more than one employment.
The calculation provides an annual maximum for all contributors who have more than oneemployment but it does not take account of those employees who, because they are incontracted-out employment, will pay primary contributions at a reduced main rate.
To ensure that these contributors are catered for, regulation 21(3) provides that for thepurposes of determining a contributors liability under the maximum calculation, aperson who pays an amount of primary Class 1 NICs at a rate of less than 11% because theyare in contracted-out employment shall be treated as having paid contributions at 11%.
