Speculation over changes to employer National Insurance contributions (NICs) has been rife in recent days, so it was no surprise when the Chancellor announced a 1.2 percentage point increase in the rate of employers NICs to 15% from next April. The increased rate will also apply to class 1A NICs (payable on benefits in kind) and class 1B NICs (payable under PAYE settlement agreements).
Perhaps more unexpected was the Chancellor's cut to the per-employee threshold at which employers start to pay NICs. For some time, this has been lower than the starting point for employees, but the reduction from £9,100 to £5,000, will mean that some businesses will pay employer NICs in respect of a larger section of their workforce than before. The new lower threshold will apply until 5 April 2028, after which it will be increased in line with the Consumer Price Index. To soften the blow for smaller businesses, the government announced that it would be increasing the £5,000 Employment Allowance to £10,500 from the next tax year and will remove the eligibility requirement for an employer NICs bill of below £100,000 in the previous tax year. According to government figures, this measure will mean that 865,000 employers pay no NICs next year.
It is worth noting that employer pension contributions are not subject to NICs, and the changes introduced by the Chancellor will increase the attraction of salary sacrifice arrangements for member contributions.
Employers can use tax-advantaged share plans to incentivise and reward their employees in a way that does not attract tax or NICs. In light of the Budget announcements, companies might think about introducing such plans or making greater use of those that they already have in place.
Generally, employers are prohibited from transferring their NICs liability to employees. One exception to this is on the exercise of options (as long as the option holder has agreed to it) and we might see more employers making use of this in future. The employee can claim tax relief for any employer NIC they pay, so for an additional rate taxpayer, this gives an effective combined tax and NICs rate of 55.25% (previously it was 54.59%) on their option gain.
