Payroll compliance is critical for SMEs, but it can quickly overwhelm non-payroll professionals. There are around 170 payroll laws in the UK, and the regulations change often.
Even one small mistake can cause problems for both employer and the employee. This guide breaks down key parts of UK payroll compliance. It explains what businesses need to follow and gives practical steps to keep payroll running smoothly.
What is payroll compliance?
Payroll compliance is when a business follows all the laws about paying its employees correctly. It covers every detail of worker pay, including salaries, tax deductions, pension contributions and payroll reporting.
These rules include systems like Pay As You Earn (PAYE), National Insurance Contributions (NICs), auto-enrolment pensions, Real Time Information (RTI) submissions and the protection of employee rights. When a company is payroll compliant, it avoids mistakes that can lead to fines or legal trouble.
Why payroll compliance matters
Following payroll rules in the UK is more than just a legal must. It’s a vital part of running a business. When payroll is done right, employees get the fair pay they deserve.
Careful attention helps stop costly mistakes before they happen. It also boosts staff morale and reduces employee turnover. A company with good payroll practices earns a better reputation with customers, employees and the wider public. In short, paying attention to payroll compliance helps a business run better.
What are the key areas of payroll compliance?
Payroll compliance means employers meet their legal obligations
There are several areas that HMRC looks at when it comes to payroll compliance. These include:
• PAYE (Pay As You Earn): Employers must deduct income tax and National Insurance from employee wages. These amounts are then sent to HMRC through the PAYE system. It’s very important that these calculations are correct so that employees are taxed at the right rate. When payroll’s accurate, there’s less chance of having to fix mistakes later.
• National Insurance Contributions (NICs): In addition to taking NICs from employee pay, businesses must also pay employer NICs. Some small businesses are eligible for Employment Allowance. This helps smaller businesses to reduce the tax they must pay.
Employers must be aware of the NIC thresholds and rates because they can change every tax year.
• Auto-enrolment and pension contributions: By law, businesses must sign up eligible employees for a workplace pension scheme. They then must pay a percentage of their earnings into the fund. If they don’t, they could face penalties from The Pensions Regulator. Employers should also explain pension options, so workers understand their benefits and how contributions support their retirement.
• Real Time Information (RTI) submissions: Employers must send payroll information to HMRC in real time. This means the details must be submitted on or before the day the employee is paid. Late or incorrect submissions can lead to fines. Using payroll software that connects with HMRC helps avoid these mistakes.
Staying on top of HMRC rules needs ongoing attention. Businesses must keep an eye on policy changes and change their processes as needed. This ongoing effort helps prevent errors before they happen.
Ensure National Minimum Wage (NMW) and National Living Wage (NLW) are applied
In the UK, ‘NMW’ stands for National Minimum Wage, which applies to workers under 21 years old or apprentices. ‘NLW’ stands for National Living Wage, which applies to workers aged 21 and over. The key difference is the age at which the respective minimum wage applies. NLW is a higher minimum wage for those 21 and older compared to the standard NMW for younger workers.
NMW and NLW rules make sure every worker earns enough to cover basic living costs and stops exploitation.
The National Living Wage is set higher to reflect the income needed for a basic but acceptable standard of living.
Every year, the UK government updates both these rates. All UK businesses must ensure they pay their employees at least the National Minimum Wage for every hour worked for those under 21. Apprentices in their first year of training, if over 21, must be paid at least the NMW.
Employees over 21 must be paid at least the NLW for every hour they work. The correct wage depends on the employee’s age and employment status.
To keep in line with the NMW/NLW rules, employers must:
- Check the new wage rates each year before the deadline to avoid underpayment
- Apply the pay rate for any hourly paid workers who are below the new minimum hourly rate
- Keep accurate records of employee hours and pay so they can show they’re following the law
- Understand the rules for apprentices and workers of different ages, because special rates apply
If a business fails to meet these requirements, it can face large fines. These can be up to double the underpayment. The government can also name the company publicly for breaking the wage rules.
Keeping informed lets employers adjust payroll budgets and protect cash flow. Employers must also be careful with other wage-related issues. For example, any deductions for uniforms or training mustn’t drop an employee’s pay below the legal minimum wage.
Employment rights: Holiday pay, sick pay and parental leave
Payroll compliance isn’t just about getting the numbers right. It’s also about respecting employee rights for pay and leave. Employers must follow laws related to holiday pay, sick pay and parental leave. This makes sure workers get the benefits they deserve.
• Holiday pay: Employees have the right to paid holiday leave. In the UK, the statutory minimum number of holiday days per year is 28 days, which is equivalent to 5.6 weeks of paid annual leave for a full-time employee working a 5-day week.
Their holiday pay should be calculated based on their regular earnings. This calculation may include overtime and commission payments when needed. It’s important that holiday pay reflects a worker’s normal income accurately.
• Statutory Sick Pay (SSP): If an employee is off work because of illness for more than three consecutive days, they may be eligible to SSP. Businesses need to know who qualifies for SSP. They must also keep clear records of absences. This protects both the employee and the employer in case of disputes.
• Parental leave: Maternity, paternity, statutory adoption, parental bereavement and shared parental leave come with pay and benefits that must be applied correctly. Businesses must stay updated on the latest changes in parental leave rights so employees get proper support during their leave.
From 6th Apil 2025, new legislation will come into effect, entitling employees to between one and 12 weeks' neonatal care leave (NCL) where their baby requires specialist neonatal care after birth. This will be available on top of any other leave the employee is entitled to, including maternity and paternity leave.
The importance of data protection for payroll compliance
Payroll data holds sensitive personal information. That’s why it’s crucial to follow the UK General Data Protection Regulation (UK GDPR) when storing and using employee data. Employers must handle this information in a lawful, fair and secure way.
They should only collect and store data for specific and lawful reasons like salary processing, tax reporting and managing pension contributions. Being clear about why data is collected builds trust with employees.
Payroll records must be stored securely. Only staff who need access should be able to see the data. Using secure systems - like encrypted payroll software, secure cloud storage and two-factor authentication – helps protect sensitive data.
If a company doesn’t follow data protection rules, it can face large fines from the Information Commissioners Office (ICO). Beyond fines, a breach can hurt a company’s reputation and weaken employee trust. Regular audits, strong encryption and staff training can lessen risk.
Payroll compliance for agency workers
When a business hires temporary or agency workers, there are rules that must be followed. These are the Agency Workers Regulations 2010. They protect temporary staff and make sure they get the same basic rights as permanent workers.
Agency workers are entitled to equal pay and the same working conditions as regular employees. They should have access to company facilities and benefits. And they have the right to paid holiday leave.
Businesses that use agency staff must track how long these workers have been employed. This makes sure that agency workers get fair treatment after 12 weeks of continuous work. Failing to do so can lead to fines or legal claims.

How to make sure your business is payroll compliant
Stay informed about payroll legislation
Payroll laws change regularly. It’s essential for every business to stay updated with the latest rules and HMRC guidance for running payroll. Keeping up to date makes it easier to run payroll correctly and avoid costly mistakes. Business can:
- Read HMRC updates, newsletters and employer bulletins. These give direct insights into changes, deadlines and updates. They help businesses stay informed about what affects payroll processes
- Businesses can also join professional payroll bodies like The Chartered Institute of Payroll Professionals (CIPP). These groups offer expert advice and help businesses understand payroll rules. They can be a helpful resource when dealing with payroll compliance issues
- It’s also a good idea to follow industry publications and news sources. Many payroll and HR websites offer detailed articles on compliance updates and new laws
- Attending events and webinars can also provide practical advice on managing payroll
Regularly checking for updates is a smart move. It helps ensure that your business doesn’t fall behind on the latest requirements. This proactive approach is key to a smooth payroll process.
Use HMRC compliant payroll software
Using HMRC-recognised payroll software is key for payroll compliance. This software is designed to reduce mistakes and make payroll management easier. It automates many tasks and ensures you follow all relevant payroll, tax and employment laws.
The benefits of using HMRC compliant payroll software include easy integration with HMRC systems. It automatically calculates PAYE, NICs and pension contributions. This means your business meets its legal obligations without extra effort.
Automated RTI submissions are another big plus. With RTI, payroll information is sent to HMRC on time and correctly. This helps prevent fines caused by late or wrong filings.
Many payroll software solutions come with employee self-service portals. These let workers check their online payslips, P60s and tax details whenever they need to. It also saves time for your payroll team.
Best practices for UK business for payroll audits
HMRC can audit your payroll at any time, often with little notice. It’s wise to do internal payroll audits regularly. These audits help you catch mistakes before they become expensive problems.
It’s recommended that you conduct a payroll audit at least once a year. Audits check that everything is running as it should. They help ensure tax codes and employee classifications are correct.
Audits also verify that all deductions and contributions match government rules. They cross-check employee hours, wages and benefits for accuracy. Modern payroll systems often use AI to help with these checks.
AI-powered payroll tools can flag unusual issues like duplicate payments or wrong tax codes. They can spot cases where an employee is being paid below the minimum wage. Custom payroll reports can highlight these exceptions for double-checking.
For small businesses that handle payroll in-house, hiring an external expert for an independent payroll audit every year is a good idea. Another option is to outsource payroll entirely. In those cases, payroll audits are usually part of the service.

What are the consequences of non-compliance with payroll legislation in the UK?
Not following payroll rules in the UK can lead to serious consequences. If a company doesn’t comply, it can face large fines from HMRC. It might also face legal action.
Non-compliance can damage a company’s reputation. It can lead to employee dissatisfaction and low morale, hurting business productivity. In some cases, it can even lead to criminal charges.
Fines for payroll non-compliance can range from a few hundred pounds for small mistakes to tens of thousands for major breaches. For example, not paying the National Minimum Wage is taken very seriously. Penalties for errors like underpayment of wages, late payments or wrong reporting can be steep.
The size of the fine usually depends on the company’s size and the type of mistake. Sometimes, companies that don’t follow the rules are publicly named. Public naming can seriously hurt a company’s reputation.
Examples of fines and penalties for non-compliance of payroll law
In 2024, 524 employers in the UK were publically named on the .gov.uk website for not following payroll rules. They had failed to pay the National Minimum Wage to their workers.
These companies were ordered to pay nearly £16 million in back wages. They also faced fines of up to 200% of the amount they’d underpaid. Not only did they have to pay, but they also suffered damage to their reputation.
How outsourcing makes payroll compliance easier for SMEs
Payroll compliance is a core part of running any business. But keeping up with around 170 payroll laws is a real challenge. For many SMEs, staying compliant on their own can be challenging.
By staying informed, using the right payroll software and doing regular audits, employers can avoid costly mistakes. A good payroll system builds trust with employees. Workers expect to be paid correctly and on time.
Mistakes like incorrect hours or wrong deductions can lead to underpayments or overpayments. These errors frustrate staff and may lead to legal disputes. They can also result in higher staff turnover, which hurts the business.
Many businesses find that outsourcing payroll makes this process much easier. When you outsource, you work with experts who keep up to date with the latest rules. These experts use HMRC-recognised software and follow best practices to keep every detail in check.
Outsourcing also frees up time so you can focus on growing your business. It reduces the risk of mistakes that could lead to fines or legal trouble. With so many payroll laws and constant changes, businesses need skilled staff and reliable software to stay compliant.
A proactive approach to payroll compliance protects your business from penalties. It builds trust with your employees and improves overall payroll efficiency. Outsourcing is one way to ensure your payroll is handled properly.
