If you employ even one person, you need payroll software that files correctly with HMRC every time you pay them. The short answer for most UK small businesses in 2026: BrightPay and Sage are the two most widely used dedicated payroll tools, while Xero and QuickBooks are the obvious picks if you want payroll built into the accounting software you already use. The right choice depends on how many people you pay, whether you already keep your books in a cloud tool, and how much of the pension and reporting admin you want handled automatically.
Payroll is one of those bits of uk small business software that has to be right rather than clever. Get it wrong and you underpay staff, miss a pension deadline, or file late with HMRC and collect a penalty. This guide compares the main options, explains the jargon, and gives realistic costs so you can shortlist quickly.
What payroll software actually has to do
Any payroll tool you pick must be HMRC recognised and support Real Time Information, or RTI. RTI is the system where you report pay and deductions to HMRC on or before the day you pay staff, rather than once a year. HMRC keeps a public list of recognised payroll software, and every tool below is on it.
Beyond RTI, good payroll software should:
- Calculate PAYE income tax, National Insurance and student loan deductions automatically.
- Handle statutory pay: sick pay, maternity, paternity and shared parental leave.
- Manage auto-enrolment pensions, including assessing who must be enrolled and sending contribution files to your provider (Nest, The People’s Pension, Smart Pension and similar).
- Produce payslips, P60s and P45s.
- Submit an Employer Payment Summary and full payment submission each pay run.
If you are still deciding whether payroll even sits with you or an accountant, remember that changes such as day-one employment rights and a possible National Insurance cut for under-25s make accurate records more important, not less. The software is only part of the job; the process around it matters too.
The main options for 2026
BrightPay
BrightPay is a firm favourite with UK accountants and small employers, partly because of its licence-based pricing rather than a per-employee monthly fee, which can work out cheaper if you have a stable headcount. It handles auto-enrolment, statutory payments and RTI cleanly, and has a cloud version alongside the desktop app. If you run payroll yourself and want something built specifically for the job, it belongs on your shortlist.
Sage Payroll
Sage is the incumbent many UK businesses grew up with. Sage Payroll is a mature, well-supported product that scales from a handful of employees upwards, and it links to Sage Accounting if you use it. It tends to sit at the pricier end, but you are paying for depth and phone support.
Xero Payroll and QuickBooks Payroll
If your books already live in Xero or QuickBooks, adding their payroll module keeps everything in one place, so wages post straight to your accounts. Both are solid for smaller teams. Xero Payroll is well regarded for auto-enrolment handling, and QuickBooks bundles payroll into its subscription tiers. The convenience is real, though very complex payrolls sometimes outgrow them.
FreeAgent
Popular with contractors, freelancers and small limited companies, FreeAgent includes payroll within its accounting package and is free for many customers of NatWest, Royal Bank of Scotland and Mercantile business banking. If you are a director paying yourself a small salary plus dividends, it is often all you need. It is worth reading alongside our guide to the best business bank accounts, because your bank may effectively hand you the software.
The names you may not have shortlisted
Two or three challengers are worth a look if standard payroll feels like a chore. PayFit is a modern, automation-first payroll and HR platform aimed at growing small and medium teams, designed to reduce manual steps. Staffology, now part of IRIS, is a cloud payroll and HR tool with an open approach that suits businesses wanting integrations. And Employment Hero bundles payroll with wider HR, onboarding and benefits, which appeals if you want people management and pay in one system. None of these are household names, and that is exactly why they are worth a demo before you default to the big four.
Payroll software compared and costed
Prices below are indicative market ranges for a small employer in 2026, not quotes. Payroll pricing changes often and depends on employee count, so always confirm on the vendor’s site before you buy.
| Tool | Best for | Rough cost basis | Pension auto-enrolment |
|---|---|---|---|
| BrightPay | Owners who want dedicated payroll, and accountants | Annual licence rather than monthly per-head | Yes |
| Sage Payroll | Established firms wanting depth and support | Monthly subscription by employee band | Yes |
| Xero Payroll | Businesses already using Xero accounting | Add-on to a Xero subscription | Yes |
| QuickBooks Payroll | Businesses already using QuickBooks | Included in or added to a QuickBooks plan | Yes |
| FreeAgent | Directors, contractors and micro companies | Free with some business bank accounts, else monthly | Yes |
| PayFit | Growing teams wanting automation and HR | Monthly, typically per-employee | Yes |
| Employment Hero | Teams wanting payroll plus HR in one | Monthly, per-employee | Yes |
As a rough guide, per-employee cloud payroll add-ons in the UK commonly land somewhere between a few pounds and around £10 per employee per month, with a base fee on top. Licence-based tools like BrightPay can be cheaper for a settled team because you are not paying more every time headcount ticks up. The honest takeaway: at small scale the price differences are modest, so pick on fit and reliability, not on saving a fiver.
How to choose the right one for you
Work through these questions in order:
- Do you already use cloud accounting? If you are committed to Xero or QuickBooks, start with their payroll module. One login, one dataset, wages posted automatically.
- Do you run payroll yourself or does an accountant? If your accountant does it, ask what they use. Many use BrightPay or Sage, and it is easier to sit on the same system.
- How much will you grow? If you plan to hire steadily, a tool with strong HR features like PayFit or Employment Hero saves you bolting on separate systems later.
- How complex is your pay? Shift work, variable hours and lots of statutory leave reward a dedicated payroll tool over a light accounting add-on.
Whatever you choose, budget for it alongside your other running costs. Payroll sits in the same monthly bucket as your accounting subscription, card payment fees and, once you cross the threshold, the admin that comes with VAT registration. Seeing them together stops payroll feeling like a surprise line item.
Frequently asked questions
Do I legally need payroll software?
You do not have to buy software, but you must report to HMRC in real time if you pay employees. HMRC offers free Basic PAYE Tools for employers with fewer than 10 staff, though it does not produce payslips or handle auto-enrolment well, so most businesses find paid software easier once they have any real complexity.
Can I run payroll for just myself as a company director?
Yes, and this is common. A single-director company paying a modest salary is straightforward, and tools like FreeAgent or BrightPay handle it comfortably. You still need to submit RTI reports each time you pay yourself, even if the amount is below the tax threshold.
Does payroll software handle workplace pensions?
The good ones do. Auto-enrolment means you must assess staff and enrol eligible workers into a pension, then send contribution data to your provider. BrightPay, Sage, Xero, QuickBooks, PayFit and the others listed all support this and connect to major providers such as Nest and The People’s Pension. Always confirm your specific pension provider is supported before committing.
What happens if my payroll filing is late?
HMRC can charge penalties for late full payment submissions, rising with the number of employees and repeated lateness. Filing on or before payday is the safe habit. This is one reason automation-focused tools appeal: they cut the chance of a missed run.
Can I switch payroll software mid-year?
Yes. You will need year-to-date figures for each employee to carry over so tax and NI keep calculating correctly. Most providers have an import process, and the cleanest time to move is the start of a new tax year in April, though it is possible at any point with care.
What to do next
- List your must-haves: employee count, whether you already use cloud accounting, your pension provider, and how much HR you need alongside pay.
- Shortlist two or three: pair the obvious fit (your accounting tool’s payroll, or BrightPay) with one challenger such as PayFit or Employment Hero, and book demos.
- Check HMRC recognition and pension links: confirm each tool is on the HMRC recognised list and supports your exact pension scheme.
- Ask your accountant: if they run or review your payroll, matching their preferred system usually saves time and money on both sides.
