EOR Services UKWhen it comes to running a compliant, efficient business in the UK, understanding payroll laws isn’t just useful — it’s essential. At, we help simplify the process, ensuring employers avoid penalties while keeping employees informed and empowered.

Whether you're a growing startup or an established company, knowing your obligations — and your rights — matters. This guide breaks down complex payroll legislation into easy-to-understand sections for both employers and employees.

What Is Payroll?

The process of determining and disbursing employee wages is known as payroll. It comprises deductions for things like income tax and National Insurance contributions, as well as the overall amount of money that a business pays workers during a given time period. Payroll also entails maintaining correct financial records and sending data to HM Revenue and Customs (HMRC).

Payroll in the UK is strictly controlled to guarantee that workers receive their salaries on schedule, fairly, and with the appropriate deductions and contributions.

Legal Responsibilities of Employers

Employers in the UK have several legal obligations when it comes to payroll. One of the first responsibilities is to register as an employer with HMRC before the first payday. Once registered, the employer receives a PAYE (Pay As You Earn) reference number and is expected to operate the PAYE system correctly.

Under PAYE, employers deduct income tax and National Insurance from employees’ wages before paying them. These deductions must then be reported and paid to HMRC. Employers must also provide each employee with a payslip, showing how their pay has been calculated, including hours worked, deductions, and net pay.

The PAYE System Explained

PAYE is the system HMRC uses to collect Income Tax and National Insurance contributions (NICS) from employment. If you employ people and they earn above a certain amount, you must operate PAYE as part of your payroll.

Employers must submit a Full Payment Submission (FPS) to HMRC every time they pay employees. The FPS includes details of employees' pay, tax, NICS, and other deductions. If any corrections need to be made, an Employer Payment Summary (EPS) is submitted.

It’s important to submit the FPS on or before the employee's payday. Late submissions can result in penalties unless there's a reasonable excuse.

Minimum Wage Laws

One of the most fundamental aspects of payroll law in the UK is the National Minimum Wage (NMW) and National Living Wage (NLW). These are the minimum hourly rates that workers must be paid, and they vary depending on age and whether the worker is an apprentice.

As of April 2025 (check for latest rates on GOV.UK), the rates are reviewed and typically updated every April. Employers must make sure they pay at least the current minimum wage to all employees. Failure to do so is illegal and can result in serious consequences, including fines and public naming by HMRC.

Statutory Payments

UK payroll Employers are required by regulations to make specific statutory payments to qualified workers. These consist of:

Statutory Sick Pay (SSP): Employees who are too sick to work are eligible for £116.75 per week for a maximum of 28 weeks starting in 2025.

Statutory Maternity Pay (SMP): Paid for up to 39 weeks — 90% of average weekly wages for the first 6 weeks, followed by 90% or a flat rate (whichever is lower) for 33 weeks.

Statutory Paternity Pay (SPP), Shared Parental Pay (ShPP), and Adoption Pay follow similar structures.

All payments are subject to eligibility rules regarding employment length and earnings thresholds.

Holiday Pay

Employees in the UK are entitled to a minimum of 5.6 weeks of paid holiday per year. For someone who works a five-day week, that’s 28 days. This includes bank holidays, although there’s no legal requirement to give bank holidays as paid leave—this is up to the employer.

For employees with variable hours or pay, holiday compensation is calculated using the average pay over the preceding 52 weeks. Employers must account for holiday pay accurately and ensure it is paid on time.

Deductions from Pay

Payroll laws in the UK strictly control what deductions employers can make from employees’ pay. Some deductions are required by law — such as tax, National Insurance, student loan repayments, and pension contributions. Others may be contractually agreed in writing.

Employment Rights Act 1996The protects workers against unlawful deductions. Any unauthorised deduction may lead to legal action and an employment tribunal.

Auto-Enrolment and Pensions

Real Time Information (RTI)

RTI is an HMRC system requiring employers to submit payroll data every time they pay employees, rather than once a year.

This improves accuracy, reduces fraud, and ensures HMRC has up-to-date information on income, tax, and NI contributions.

Employers must submit FPS on each payday, and EPS where adjustments are needed. Failing to comply may result in penalties.
