Key Payroll Taxes Employers Must Comply With in the UK

National Insurance Contributions (NICs)

NICs are mandatory taxes paid by the UK employers on the earnings of their employees, which are above a set limit, as well as some benefits. These payments aren’t the same as what workers make, but they help pay for state benefits like the State Pension and the NHS.

Sampling is done using the PAYE system, where the rates vary depending on the level of earnings and the form of benefit. For the 2025-26 fiscal year, key

Income Tax (PAYE System)

Payment As You Earn (PAYE) is a way for companies to collect taxes. It means that income tax and social contributions like National Insurance are taken out of a worker’s salary or wages before the worker is paid. The employer will then pay these amounts that have been deducted on behalf of the employee to the corresponding national tax authority.

Apprenticeship Levy

Large employers in the UK are taxed over £3 million a year to pay for the Apprenticeship Levy. This tax forms a digital fund to pay for apprenticeship training and skill-building. The levy funds that aren’t used expire after 24 months. Small businesses get help from the government with funding, and larger businesses can give the leftover funds to other businesses. The government introduced the initiative to improve skills and allow flexibility in training current employees or recruiting new ones.

Pension Auto-Enrolment Contributions

Pension schemes consist of recurring payments to a retirement fund, often a percentage of salary, made by employees, employers, or a combination of the two. The National Pension System (NPS) in India is mandatory, so employees have to make contributions, including 10 percent of the yearly salary with an equivalent state contribution to Tier-I accounts.

Hike in Employment Allowance

It has been raised by £5,000 to £10,500. The Employment Allowance is a government program that lets businesses lower the amount of National Insurance their employers pay. This is a positive development for the numerous businesses that can enjoy this allowance.

Note: Employment Allowance can only be used to the extent of the value of the Employer’s NIC you are supposed to pay. Because of this, a qualified business with Employers National Insurance of £1000 will only have to pay that amount.

Decrease in Secondary Threshold

Employers’ National Insurance contribution secondary threshold has now been scaled down to £5,000 as compared to £9,100. This implies that now employers will begin to pay National Insurance at reduced salary levels.

Rise in the NIC rate of Employers

The NIC rate of employers has increased by 13.8% to 15%. This will have a direct effect on the value of National Insurance that the employers are obligated to pay.
