A guide to payroll compliance

As a small business owner, it’s important to stay on top of your payroll. One of your core responsibilities as an employer is ensuring you calculate your employees’ wages correctly and pay the correct amount in deductions, including National Insurance and income tax.

But it can be complicated — especially when payroll legislation changes. Luckily, payroll software makes it easier than ever to stay on top of any changes and keep things running smoothly.

In this guide, we’ll explain what payroll is, why compliance with payroll rules is so important, and what you can do to ensure you stay up to date to help you stay compliant.

Payroll tax compliance: In summary

• Payroll compliance isn’t just about paying wages; it’s a multi-layered employer duty. It requires running an accurate PAYE process and calculating correct Income Tax and National Insurance contributions (NICs).

• Running non-compliant payroll processes can result in steep financial and reputational consequences. HMRC monitors your submissions and hands out fees for missing Full Payment Submission (FPS) deadlines, making late payments, and inaccuracies.

• HMRC-recognised software is an essential tool that can support businesses during regulatory reviews. Platforms like QuickBooks can help you ensure compliance by replacing unorganised spreadsheets with structured digital records.

What is payroll compliance?

Payroll compliance refers to the process of accurately calculating employee wages, expenses and taxes. It means ensuring you’re following all the right rules and HMRC regulations and meeting your responsibilities as an employer, including:

• Processing correct employee pay

• Accurately deducting tax and pensions

• Submitting accurate, timely reports to HMRC.

Payroll tax compliance is important as it ensures your employees are getting paid the correct amount at the correct time. It also helps you avoid any possible penalties you may incur for non-compliance.

For example, if you incorrectly calculate the amount of National Insurance or Income Tax you have to pay, HMRC will investigate your report. They’ll want to find out whether the error was due to a lack of reasonable care, deliberate, or deliberate and concealed. 

If the error is found to have been deliberate and concealed, you could be facing a 100% fee, based on the amount of the extra tax due on top of what you already owe in penalties.

How to stay compliant with UK payroll laws

As a UK business owner, it’s your responsibility to pay and tax your employees correctly. Government guidelines may seem to shift, but the basics of payroll compliance are quite straightforward once you have the right processes and tools in place.

Follow the three-step payroll process

Pay As You Earn (PAYE), is the official system used across the UK to calculate how much National Insurance and Income Tax to deduct from employee wages. To use PAYE, follow the three-step process:

Step 1: Calculate initial wages

You’ll need to use your payroll software to process employee wages. You can use it to calculate their gross pay – what they earn before tax, including additional pay and bonuses.

Step 2: Determine NICs and Income Tax Deductions

You can also use your payroll software to work out what needs to be deducted from their gross pay. You’ll need to use employee tax codes to calculate individual deductions and contributions.

Step 3: Process payslips and submit to HMRC

Finally, you’ll need to create accurate payslips that detail gross pay, deductions and final net pay. On or before payday, you’ll then need to send all the required information to HMRC through approved software.

Keep accurate records

It may sound obvious, but a key part of proper payroll accounting is keeping accurate records.

You should work together with your HR team to achieve payroll compliance here, as each employee’s personal information and circumstances can affect their payroll. For example, changes such as promotions, pay rises or extended periods of leave can dictate the benefits they’re entitled to and, therefore, the deductions you need to include.

Having one system or software, such as QuickBooks, can help you stay on top of this. The combined platform makes it easier to ensure changes recorded in one area are automatically carried over to avoid mistakes and penalties.

Automatically enrol employees into pension schemes

One key element of private pension schemes is automatic enrolment. This is when workers are automatically enrolled onto the workplace pension scheme, meaning you’ll also have to contribute towards their protected pension pot.

As of February 2018, all employers are required to offer and comply with auto-enrolment to all eligible workers. It’s your duty as an employer to enrol your employees on your chosen workplace pension from the day they begin employment.

Again, you need to pay attention to these rules to ensure you’re automatically enrolling all the employees that you need to. HR should be able to help with this as they onboard new hires.

Ensure consistent employee input

We’ve talked a lot about what you need to do as a business owner. But it’s also important that your employees understand their responsibilities — not least because any mistakes they make will also reflect on you and your business. 

Workers’ payroll responsibilities can include things like: 

• Filling out regular timesheets to accurately record their working hours 

• Understanding and following your company’s expense policies

• Informing you of any relevant changes to their working status.

In addition to helping protect you from penalties, encouraging your workers to stay aware of their payroll duties can help keep them engaged as part of the company.

Keep a payroll checklist

Staying on top of deadlines, deductions, pensions, and payroll records can feel like a lot, especially when you’ve got a business to run. That’s why keeping a detailed payroll checklist can be a valuable compliance solution when managing multiple processes. It can help to keep you on track, so you don’t miss any key stages.

Your checklist could include:

• Checking when your payroll ends

• Processing new hires and leavers

• Submitting year-end payroll

• Creating P60 and P11Ds

• Preparing for the new tax year.

Managing HR payroll compliance

There are many different aspects of payroll compliance, with each overlapping with HR responsibilities and automatic enrolment rules. With this in mind, syncing with your HR team — and ensuring consistent, effective communication — is key to running payroll and tax smoothly.

For example, from the day an eligible employee begins employment, you have a duty to enrol them into a protected pension pot and contribute towards it. Your HR team will be able to help you stay on top of all new hires and their personal information, ensuring you begin paying into their pension at the right time.

Your HR team will also be able to keep you abreast of any personal updates so you can sync them with payroll. For example, extended leave, promotions and status changes can all directly affect payroll records. You’ll need to remain aware of any changes so you can ensure accurate and timely pay and deductions.

Current UK payroll compliance laws

Even when you have the correct payroll processes in place, staying on top of current compliance laws is another thing to bear in mind. However, the majority of what you need to know and keep an eye on are the foundational rates and parameters set by HMRC that govern payroll compliance in the UK. These include:

Secondary Class 1 National Insurance Thresholds

As an employee, you need to start paying National Insurance, where applicable,  once an employee’s gross pay exceeds the following limits:

• Weekly: £96 per week

• Monthly: £417 per month

• Annual: £5,000 per year.

National Living Wage hourly rates

You are responsible for paying the government-mandated Living Wage to all your employees aged 21 and over. This can change yearly, but is currently £12.71 per hour.

Statutory Sick Pay (SSP) and Statutory Maternity Pay (SMP)

These are the minimum amount employers need to pay employees who are too ill to work, or on maternity leave.

• Statutory Sick Pay. Employees are entitled to either £123.25 per week, or 80% of their normal average weekly earnings (whichever is lower).

• Statutory Maternity Pay. 90% of their average weekly earnings for the first six weeks, and either £194.32 or 90% (whichever is lower) for the remaining 33 weeks.

The Lower Earnings Limit (LEL)

The LEL is the minimum weekly income employees need to earn to qualify for certain state benefits without paying National Insurance. This includes the State Pension.

The current LEL for the 2026/2027 tax year is £129 per week (£559 per month or £6,708 per year).

2026 changes to payroll compliance in the UK

Payroll compliance legislation and processes are frequently tweaked, adjusted and updated by the government. It’s crucial that you stay on top of these changes to help you remain compliant with current payroll regulations.

Here are some of the headline changes from 2025 and 2026:

• Employees now qualify for Statutory Sick Pay and parental leave from the first day at work. Previously, employees were entitled to these benefits after a probation period.

• The Secondary Class 1 National Insurance rate increased from 13.8% to 15% on all earnings above £5,000.

• The Secondary Threshold reduced from £9,100 to £5,000 – meaning businesses may need to pay more in employer NICs.

• Employment Allowance rose to £10,500, and the eligibility threshold has been removed – this may benefit a wider range of businesses.

• The National Living Wage for workers aged 21 and over increased to £12.71 per hour.

• Wage rates for 18-to-20-year-olds have risen to £10.85, and 16-17-year-olds and apprentices, £8.00.

• Statutory Sick Pay (SSP) rose to £123.25 per week, while Statutory Maternity Pay and Family Leave Pay increased to £194.32 per week.

• The Lower Earnings Limit adjusted to £129 per week.

• Small Employers’ Relief (SER) increased to 109%, with the £45,000 threshold staying the same.

With these changes in mind, a good payroll system will help you make any necessary adjustments to your processes that are affected by new legislation.

What are the risks of payroll non-compliance?

Your business could face a range of consequences if you’re found to be running a non-compliant payroll. HMRC monitors and reviews all submissions and administer fees for errors and late payments – whether they occur due to a lack of reasonable care or are deliberate.

Payroll compliance risks include:

• Late filing. Missing deadlines for Full Payment Submission (FPS) or Employer Payment Summary (EPS) forms.

• Late payments. Delays in sending collected PAYE totals to HMRC.

• Inaccurate reporting. Mistakes calculating Income Tax or NICs. These can lead to penalties of up to 100% of the underpaid amount.

• Record-keeping failures. Forgetting to secure payroll history, which can result in steep statutory fines.

Additional benefits of staying compliant with payroll laws

Aside from compliance itself – and avoiding the related fines – there are many wider business benefits to ensuring you remain compliant with current payroll laws.

More robust audit trails

One of the main benefits of payroll software is the protection it can offer you in case of investigation. Utilising HMRC-approved software helps by creating clean, historical digital audit trails. These are detailed records of relevant transactions and payments, including supporting information such as invoices and purchase orders. 

A sound audit trail can be helpful in protecting your business (and your reputation) if you find yourself under investigation for anomalies or errors. For example, HMRC may review your records for discrepancies. In this instance, having detailed, verifiable transaction trails helps you prove that minor errors were unintentional, rather than a deliberate attempt to conceal underpaid amounts. 

Automating your payroll with software also reduces any risks of human error and miscalculations, protecting you against any potential penalties.

Keeping audit trails also mean you can: 

• Ensure your bookkeeping is accurate

• Provide detailed insight into your business

• Protect you against fraud.

Better employee satisfaction

Accurate, timely payroll means you’re more likely to have workers that are content with their employer. In short, when you make sure employees are paid the right amount, on time has a direct impact on company culture. Consistently calculating correct deductions for Income Tax, National Insurance contributions, and workplace pensions fosters organisational trust in the long term.

When it comes to payslips, payroll compliance can prevent the drop in staff morale and high turnover rates that often follow chronic payment errors or delayed pension contributions.

Improved business reputation

Maintaining a track record of flawless payroll compliance signals financial health and corporate responsibility to external stakeholders, and prospective clients and employees. It also minimises the risk of public regulatory audits or legal disputes that could damage your business’ reputation. can help with wider company reputation as a reliable business to work for.

Clearer financial picture

A compliant payroll system requires your records to be highly organised and integrated with your wider business accounts. Consistent accuracy eliminates messy, manual data tracking and provides a reliable view of true staffing costs. Overall, this can help you make better data-led decisions, budget effectively, and plan long-term growth strategies. 

Compliance features to look for in a payroll software

Every business is different, so it’s a good idea to do your research into available payroll compliance services and tools to ensure you find the best fit. A modern, HMRC-compliant system should help with:

• Providing secure, detailed audit trails. This will help to protect your reputation during a review from HMRC

• Handling GDPR compliance for payroll by encrypting sensitive, confidential information. This would include the likes of NI numbers and salary figures

• Seamless integration with your business accounts, to eliminate manual formula slips

• Automatically applying changing tax brackets like SSP and NI deduction rates to ensure consistency

• Direct integration with HMRC. This allows you to submit Real-Time Information (RTI) on time and avoid late-submission fees.

Streamline your payroll processes with QuickBooks

QuickBooks’ industry-leading payroll software lets you easily handle all of this, so you’re not left feeling stressed when payday comes around. It allows you to integrate with your existing accounting software to streamline your workflow and ensure you’re completing all your key tasks correctly and in good time.
