If the employer had contracted with the utility companies, builder and so on to providethe services leading to the expenses, the liability is under Class 1A. The Class 1earnings would then be £1000 monthly and the thresholds reached on different dates. Thefirst payment of earnings for primary NICs is July (£4000 cumulative salary); and inAugust (£5000 cumulative salary) for secondary NICs.

If the employer decides to ‘pay on account’ (NIM12026)Class 1 NICs are due from the first month and the employer adjusts the final payment atthe end of the year to ensure the same amount of NICs is paid as in the example.

  • The above example is for a tax year prior to 6 4 2003. From 6 4 2003, a new primaryliability was introduced on all earnings above the Upper Earnings Limit. This should betaken into account when applying the example to tax years 2003/2004 onwards. Full guidanceon the new primary liability on earnings above the Upper Earnings Limit is provided at NIM01100.
