Best Payroll Software for Small Businesses UK
Running payroll for a small business in the UK involves more than just paying your employees. You need to calculate income tax and National Insurance, handle student loan deductions, manage auto-enrolment pensions, submit Real Time Information (RTI) reports to HMRC, and produce payslips — all accurately and on time. Get it wrong, and you face penalties from HMRC and disgruntled employees.
For many small business owners, payroll is the most stressful part of their administrative workload. The right software can take the pain out of the process, automating calculations and submissions so you can focus on actually running your business. In this guide, we review the best payroll software for UK small businesses in 2026.
What Small Business Payroll Software Must Do
UK payroll software needs to handle several critical functions. At the bare minimum, it must calculate PAYE income tax and National Insurance contributions for each employee based on their tax code and earnings. It must also handle statutory payments including Statutory Sick Pay (SSP), Statutory Maternity Pay (SMP), and Statutory Paternity Pay.
RTI compliance is mandatory. Every time you pay your employees, you must submit a Full Payment Submission (FPS) to HMRC on or before the pay date. At the end of each tax month, you may also need to submit an Employer Payment Summary (EPS). Your software must handle both of these automatically.
Auto-enrolment pension management is another essential feature. Since 2018, all employers must enrol eligible workers into a qualifying pension scheme and make minimum contributions. Your payroll software should calculate pension contributions, manage opt-in and opt-out requests, and integrate with your pension provider.
According to HMRC's payroll guidance, employers must keep payroll records for at least three years after the end of the tax year they relate to. Your software should store these records securely.
The Best Payroll Software for UK Small Businesses
Moneysoft Payroll Manager
Moneysoft is one of the most popular payroll solutions for UK small businesses, and for good reason. It is affordable, reliable, and covers all the essentials: PAYE calculations, RTI submissions, auto-enrolment management, and payslip generation.
The software runs on Windows (with a cloud version also available) and is updated automatically when tax rates change. Moneysoft handles up to 100 employees on its standard licence, with pricing starting at around £99 per year for up to 25 employees. This makes it one of the most cost-effective options available.
The main limitation is that Moneysoft is a payroll-only tool. It does not integrate directly with most accounting software, so you will need to manually enter payroll journal entries into your accounts. For businesses that want an all-in-one solution, this creates extra work.
Xero Payroll
Xero offers payroll as an add-on to its accounting platform. This means your payroll data flows directly into your accounts, eliminating manual journal entries and ensuring your profit and loss statement is always up to date.
Xero Payroll handles PAYE, RTI, auto-enrolment, and payslips. It supports employee self-service, allowing staff to view payslips and request leave through an online portal. The integration with Xero's broader accounting features is seamless.
However, Xero Payroll is not cheap. It is charged per employee per month on top of your Xero subscription, and the costs scale quickly as your headcount grows. For a business with ten employees, the combined Xero and payroll cost can easily exceed £80 per month.
For sole traders without employees who use Xero for accounting, the payroll add-on represents unnecessary cost. Our Accounted vs Xero guide covers the broader pricing comparison.
Sage Payroll
Sage has been a payroll provider in the UK for decades, and its expertise shows. Sage Payroll handles everything from basic PAYE to complex scenarios including multiple pay frequencies, attachment of earnings orders, and statutory payments.
Sage offers both cloud and desktop versions. The cloud version integrates with Sage Accounting, while the desktop version can export data to various accounting platforms. Pricing starts at around £7 per month for up to five employees.
Sage's depth of features is impressive, but the interface can be intimidating for first-time users. Small business owners without a background in payroll may find the learning curve steep. For a direct comparison with other options, see our Sage vs Xero vs Accounted article.
BrightPay
BrightPay is a well-regarded payroll solution developed in Ireland and fully compliant with UK tax rules. It offers a clean interface, strong automation features, and excellent support for auto-enrolment. BrightPay Connect adds cloud features including employee self-service, online payslips, and remote access.
Pricing is based on an annual licence fee, typically around £139 per year for unlimited employees. This flat-rate model makes BrightPay particularly cost-effective for businesses with larger teams.
BrightPay integrates with several accounting platforms and pension providers. The automatic pension submission feature is a standout, reducing the manual work involved in managing auto-enrolment.
HMRC Basic PAYE Tools
HMRC provides a free payroll tool that handles basic PAYE for businesses with fewer than ten employees. It calculates tax and National Insurance, produces payslips, and submits RTI reports. For very small businesses with straightforward payroll needs, this can be sufficient.
The limitations are significant, however. HMRC's tool does not handle auto-enrolment, does not integrate with accounting software, and offers minimal reporting. The interface is functional but not user-friendly. It is a budget option, not a business-grade solution.
Moorepay
Moorepay offers a managed payroll service where they handle the processing for you. You provide employee data and any changes, and Moorepay calculates pay, generates payslips, and handles RTI submissions. This hands-off approach suits businesses that want to outsource payroll entirely.
The cost is higher than self-service software, but the time savings can be substantial. Moorepay also handles year-end processing, P60s, and auto-enrolment management. For businesses without a dedicated payroll person, outsourcing to Moorepay can be a sensible investment.
Key Features to Evaluate
When comparing payroll software, consider these factors:
RTI compliance — Essential. All options listed above handle this, but check that submissions are automated rather than requiring manual triggers.
Auto-enrolment — Must support your pension provider. Check integration with NEST, The People's Pension, or whichever scheme you use.
Scalability — What happens when you hire your sixth, tenth, or fiftieth employee? Some tools charge per employee, making costs unpredictable.
Accounting integration — Does payroll data flow into your accounting software? Manual re-entry is time-consuming and error-prone.
Employee self-service — Can employees view payslips, check leave balances, and update personal details online? This reduces your administrative burden.
Support — Payroll mistakes can be costly. Ensure your provider offers responsive support, particularly around year-end and when HMRC rules change.
The CIPD's reward management research indicates that payroll errors are among the top causes of employee dissatisfaction. Reliable software is essential for maintaining trust with your team.
Payroll Tips for Small Businesses
Beyond choosing the right software, these practices will help you run payroll smoothly:
Set a consistent pay schedule. Whether you pay weekly, fortnightly, or monthly, stick to the same dates. This helps with cash flow planning and employee expectations.
Process payroll early. Do not wait until pay day to run payroll. Processing a few days early gives you time to resolve any issues before employees expect their pay.
Keep records meticulously. Payroll records must be retained for at least three years. Your software should handle this automatically, but verify that records are being stored correctly.
Stay updated on rate changes. Tax thresholds, NI rates, minimum wage, and pension contribution rates change regularly. Ensure your software is updated before each new tax year.
Consider outsourcing if payroll is taking too much time. For very small businesses, a managed payroll service or your accountant handling payroll may be more efficient than doing it yourself.
Our Recommendation
For most UK small businesses, BrightPay offers the best balance of features, usability, and value. Its flat-rate pricing means costs are predictable regardless of headcount, and its auto-enrolment features are best-in-class.
If you already use Xero or Sage for accounting, their respective payroll add-ons provide the convenience of integration, though at a higher cost.
For sole traders and freelancers without employees, payroll software is unnecessary. Accounted handles everything you need for self-employed tax and accounting. Visit our features page to see how Accounted can simplify your financial admin.
