Payroll is one of those things you can't afford to get wrong. Miscalculate an employee's tax, miss an HMRC submission deadline, or botch your auto-enrolment pension contributions, and you're looking at automatic penalties starting at £100 per month — plus the stress of dealing with HMRC while you're supposed to be running a business.The good news is that modern payroll software handles most of this for you. The right platform will calculate income tax and National Insurance automatically, submit Real Time Information (RTI) to HMRC on or before payday, manage auto-enrolment pension contributions, generate payslips, and keep you compliant without you needing to become a payroll expert.But choosing the right one isn't straightforward. There are genuinely good options from under £100 a year to over £3,000, and the best choice depends on how many employees you have, whether you're already using accounting software, and how much you want to handle yourself versus outsourcing.This guide compares the leading payroll software options for UK small businesses in 2026, with current pricing, honest assessments of what each platform does well (and where it falls short), and the regulatory changes you need to know about this tax year.Table of ContentsWhat Changed for Payroll in 2025/26 and 2026/27What to Look for in Payroll SoftwareThe Best Payroll Software for UK Small BusinessesQuick Comparison TableFree vs Paid Payroll SoftwareCloud vs Desktop Payroll SoftwareWhat Features Are Actually Worth Paying For?How to Switch Payroll Software Without DisasterCommon Payroll Mistakes Small Businesses MakeNext StepsFAQsWhat Changed for Payroll in 2025/26 and 2026/27Before choosing software, you need to know what's changed — because the 2025/26 and 2026/27 tax years brought several significant shifts that directly affect which features your payroll software needs to support.Employer National Insurance Increased to 15%From April 2025, the employer NIC rate rose from 13.8% to 15%, and the Secondary Threshold (the point at which employers start paying NICs on an employee's salary) dropped from £9,100 to £5,000. This is a material cost increase for every small business with employees. Your payroll software needs to apply these rates correctly — and if you're using older or unpatched software, you could be underpaying NICs without realising it.Employment Allowance Rose to £10,500The Employment Allowance — which reduces your employer NIC bill — increased to £10,500 from April 2025. If your business qualifies (most small businesses do, unless you're the sole employee and also a director), this can offset a significant portion of the NIC increase. Make sure your payroll software claims this automatically.Making Tax Digital for Income Tax LaunchedFrom 6 April 2026, self-employed individuals and landlords with gross income over £50,000 must keep digital records and submit quarterly updates to HMRC. While this primarily affects self-assessment rather than PAYE payroll, it signals the direction of travel: HMRC is digitalising everything, and your payroll software needs to be on the GOV.UK recognised list of compatible providers.Mandatory Payrolling of Benefits in Kind Coming April 2027This one's a heads-up rather than an immediate action item. From April 2027, most employers will be required to report benefits in kind (company cars, private medical insurance, etc.) through payroll rather than via P11D forms after the year end. Voluntary registration for 2026/27 closed on 5 April 2026, but if you're choosing new payroll software now, check that it supports benefit-in-kind payrolling — you'll need it within a year.Auto-Enrolment Thresholds for 2026/27The auto-enrolment qualifying earnings band remains £6,240 to £50,270 for 2026/27, with the trigger threshold for automatic enrolment at £10,000. Total minimum contributions remain at 8% (5% employee, 3% employer). Your payroll software must handle this automatically — manual calculation is a recipe for errors and regulatory penalties.What to Look for in Payroll SoftwareNot every feature matters equally. Here's what genuinely matters for a UK small business, in order of priority.HMRC recognition. Your software must be on the GOV.UK list of payroll software recognised by HMRC for RTI submissions. Do not use any platform that isn't on this list — it's not legally compliant.Automatic tax and NIC calculations. The software should calculate income tax (using the correct tax code for each employee), employee NICs, employer NICs at 15%, and student loan deductions without manual intervention.RTI submissions. Full Payment Submissions (FPS) must be sent to HMRC on or before each payday. Employer Payment Summaries (EPS) are submitted monthly where applicable. Your software should handle both.Auto-enrolment pension management. The software should assess employee eligibility, calculate contributions, and integrate with your pension provider (NEST, People's Pension, Smart Pension, etc.).Payslip generation. Digital payslips that employees can access independently reduce your admin burden significantly.Statutory pay calculations. SSP, SMP, SPP, ShPP, and SAP all have specific rules and rates. Your software should calculate these automatically when you input the relevant dates and circumstances.Year-end reporting. P60s, P11Ds (until mandatory payrolling takes over), and final RTI submissions at year end should be handled within the software.Everything beyond this — employee self-service portals, mobile apps, AI-powered analytics, multi-currency support — is useful but secondary. Get the fundamentals right first.The Best Payroll Software for UK Small Businesses1. Sage Payroll — Best All-Round for UK Small BusinessesSage is the most widely used payroll software among UK small businesses, and for good reason. It's purpose-built for UK compliance, handles PAYE, RTI, auto-enrolment, CIS (Construction Industry Scheme), and statutory payments out of the box, and doesn't require you to buy any additional accounting software to function.The platform includes employee self-service for payslips and tax documents, integrates with Sage Accounting if you use it (but works perfectly well standalone), and is fully cloud-based with automatic updates for tax year changes.Pricing (2026): Essentials plan starts at £20 per month for up to 10 employees, plus £1.30 per additional employee per month. For a 20-employee business, that's roughly £360 per year.Best for: Small businesses that want a dedicated, standalone payroll solution with strong HMRC compliance and don't want to rely on an accounting platform to run payroll.Limitations: The interface can feel dated compared to newer competitors. The learning curve is steeper than Xero or QuickBooks if you're completely new to payroll.2. BrightPay — Best Value for Micro-Businesses and AccountantsBrightPay has long been the tool of choice for UK accounting practices running payroll for multiple clients, and it's equally strong for small businesses running their own payroll. For the 2026/27 tax year, BrightPay is transitioning from its legacy desktop product to a cloud-first model, so new users should opt for BrightPay Cloud.Features include RTI, auto-enrolment, CIS, employee self-service, and a client portal. The desktop product was renowned for its one-time annual licence pricing, which made it exceptionally cost-effective.Pricing (2026): Cloud pricing starts at approximately £6 per employee per month. The legacy desktop licence (where still available) starts at around £139 per year — one of the cheapest options in the market for a full-featured payroll platform.Best for: Micro-businesses and accountants who want maximum features at minimum cost. Also strong for businesses that value having their accountant access the same system directly.Limitations: The cloud transition means some users are on an older desktop product that will eventually be phased out. Check which version you're buying.3. Xero Payroll — Best for Businesses Already Using XeroXero's payroll module is built directly into its accounting platform, which makes it seamless if you're already a Xero user. Payroll runs within Xero, and everything flows automatically into your accounts — no manual journal entries, no reconciliation headaches.It handles RTI, auto-enrolment, payslips, and statutory payments. The mobile app allows you to process payroll from your phone, which is genuinely useful for founders who aren't always at a desk.Pricing (2026): Xero doesn't offer a payroll-only plan. You need a Xero accounting subscription (from £15/month for Starter, £33/month for Standard, or £47/month for Premium), and payroll is included with Standard and Premium plans. For small teams on the Starter plan, payroll costs an additional £5/month plus £1 per employee.Best for: Small teams of 1–15 employees who are already using Xero for accounting and want everything in one place.Limitations: No standalone payroll option. If you don't use Xero for accounting, this isn't the right choice. Advanced payroll features (CIS, complex statutory pay scenarios) are more limited than Sage or BrightPay.4. QuickBooks Payroll — Best for QuickBooks UsersQuickBooks Payroll follows the same logic as Xero: it integrates directly with QuickBooks accounting, making it an excellent choice if you're already in that ecosystem. Payroll data flows into your accounts automatically, and the platform handles RTI, auto-enrolment, payslips, and employee self-service.Pricing (2026): Core payroll starts at £4 per month plus £1 per employee. Premium plan at £8 per month plus £1.50 per employee adds next-day direct deposit and HR features.Best for: Small businesses already using QuickBooks for accounting who want integrated payroll without switching platforms.Limitations: Like Xero, it's best suited as an add-on to the accounting platform rather than a standalone payroll tool. CIS support and advanced reporting are more limited than dedicated payroll platforms.5. Moneysoft Payroll Manager — Best Budget OptionMoneysoft is the no-frills option for businesses that need reliable payroll on a tight budget. It handles PAYE, RTI, auto-enrolment, CIS, and statutory payments. The interface is basic but functional, and at £90 per year it's hard to argue with the value.Pricing (2026): £90 per year. That's it. No per-employee charges.Best for: Micro-businesses with simple payroll needs who want a cheap, reliable, HMRC-compliant solution without monthly subscription costs.Limitations: Basic reporting. No employee self-service portal. The interface is dated. Limited integrations with other software.6. Employment Hero — Best Free OptionEmployment Hero offers a free tier that includes payroll and HR for small teams. It's cloud-based, covers RTI and auto-enrolment, and provides a combined HR and payroll platform at no cost for basic functionality.Pricing (2026): Free tier available. Paid plans from approximately £8 per employee per month for additional HR features.Best for: Very small businesses (1–5 employees) that want a combined HR and payroll platform and want to start without any upfront cost.Limitations: The free tier has feature limitations. The platform is relatively new to the UK market compared to Sage or BrightPay. Support options on the free plan are limited.7. PayFit — Best for Automation and Growing TeamsPayFit focuses on simplifying payroll through automation and a clean, modern interface. It handles RTI, auto-enrolment, statutory payments, and benefit-in-kind reporting, and includes HR features like leave management and onboarding.Pricing (2026): From approximately £17 per month plus £6 per employee. More expensive than basic options but includes significantly more automation and HR functionality.Best for: Growing businesses (10–50 employees) that want a modern, automated platform combining payroll and HR, and are willing to pay more for a better user experience.Limitations: Higher cost than basic payroll tools. May be more than a micro-business needs.8. Deel — Best for International PayrollIf your business employs people or engages contractors outside the UK, Deel handles multi-country payroll, tax compliance, and contract generation across 150+ countries. It's overkill for a purely UK operation, but essential if you have international team members.Pricing (2026): UK payroll from approximately $29 per employee per month. Employer of Record (EOR) services from $599 per employee per month.Best for: Businesses with international employees or contractors who need compliant payroll and payments across multiple jurisdictions.Limitations: Significantly more expensive than UK-only solutions. Unnecessary complexity if all your employees are UK-based.Quick Comparison TableFor a business with 10 UK employees, here's what you'd pay annually (approximate, based on 2026 pricing):Moneysoft: ~£90/year — Budget, reliable, basic.BrightPay (desktop): ~£139/year — Strong features, great for accountants.Sage Payroll: ~£240/year — Best all-round UK compliance.QuickBooks Payroll: ~£168/year — Best with QuickBooks accounting.Xero Payroll: ~£396+/year — Best with Xero accounting (requires accounting subscription).Employment Hero: Free (basic) — Best no-cost starter option.PayFit: ~£924/year — Best for automation and HR integration.Deel: ~£3,480/year — Best for international teams only.The range is dramatic. A 10-person UK business can run compliant payroll for under £100 a year with Moneysoft, or spend over £3,000 with Deel. Unless you have international employees, there's rarely a reason to be at the top end of that range.Free vs Paid Payroll SoftwareWhen Free WorksHMRC offers its own Basic PAYE Tools for free, and it's perfectly adequate for businesses with fewer than 10 employees running straightforward monthly payroll. Employment Hero's free tier is another option that adds a more modern interface and basic HR features.Free payroll software works well for micro-businesses with simple needs: a handful of employees, all UK-based, no CIS requirements, no complex statutory pay scenarios.When You Need to PayThe limitations of free tools become apparent quickly as you grow. Limited or no CIS support, basic or absent reporting, no employee self-service, and minimal customer support are typical constraints. Once you have more than 5–10 employees, or your payroll involves any complexity (contractors, CIS, benefits in kind, multiple pay frequencies), a paid platform is worth the investment. At £90–£240 a year for the most popular options, the cost is trivial compared to the cost of a payroll error.Cloud vs Desktop Payroll SoftwareThe market has overwhelmingly moved to cloud-based payroll, and for most small businesses, cloud is the right choice. You get automatic updates (critical for tax year changes), access from any device, built-in data backup, and no dependency on a single computer.Desktop payroll software still exists — BrightPay's legacy desktop product being the most notable example — and it works well for businesses that want a one-time annual licence cost, prefer to keep data locally, or have unreliable internet connectivity. However, the direction of travel is clear: BrightPay itself is transitioning to cloud-first, and most new entrants to the market are cloud-only.If you're choosing payroll software for the first time in 2026, default to cloud unless you have a specific reason not to.What Features Are Actually Worth Paying For?Essential — You Need TheseHMRC-recognised RTI submissions, automatic tax and NIC calculations at current rates, auto-enrolment pension management, payslip generation, and statutory pay calculations. Every paid platform in this guide includes all of these.Worth Having — Improves Your LifeEmployee self-service portals (so employees access their own payslips and P60s without asking you), integration with your accounting software (eliminates manual journal entries), and CIS support if you work in construction.Nice but Not CriticalMobile app access, AI-powered analytics, customisable reporting dashboards, and multi-currency support. These add value for specific use cases but aren't worth paying a premium for if your payroll is otherwise straightforward.Don't Pay Extra ForFeatures you'll never use. If you have 5 UK employees and no plans to hire internationally, you don't need Deel. If you're not in construction, you don't need CIS. Be honest about your actual requirements and choose accordingly.How to Switch Payroll Software Without DisasterSwitching payroll software mid-year is possible but risky. The cleanest time to switch is at the start of a new tax year (6 April), when there's no mid-year employee data to transfer and no partial-year reconciliation to manage.If you're planning to switch, give yourself at least 4–6 weeks before the transition date. Run parallel payroll for at least one pay period (process payroll in both old and new systems and compare the results). Ensure all employee data — tax codes, NI numbers, year-to-date figures, pension contribution records — transfers accurately. Notify HMRC of the new software provider if required. And keep your old software accessible for at least 12 months after switching, in case you need to reference historical data or respond to HMRC enquiries.Common Payroll Mistakes Small Businesses MakeEven with good software, certain errors crop up repeatedly.Using the wrong tax code. If HMRC sends a P6 or P9 notice changing an employee's tax code, your software should pick this up automatically. But check — manual overrides can cause codes to stick when they shouldn't.Not claiming Employment Allowance. If you're eligible for the £10,500 Employment Allowance and you're not claiming it, you're overpaying NICs. Check your payroll software settings.Late RTI submissions. FPS must be submitted on or before payday. Late submissions trigger automatic penalties. Set up your software to submit automatically on pay day, not manually afterwards.Ignoring auto-enrolment duties. Every UK employer must assess employees for auto-enrolment eligibility and re-enrol those who've opted out every three years. Your software should handle this, but you need to action the prompts when they appear.Not keeping records for the required period. HMRC requires you to keep payroll records for at least three years after the end of the tax year they relate to. Your software should store these, but check your retention settings — and keep backups.Next StepsIf you're choosing payroll software for the first time, or considering a switch, here's the practical sequence.Work out your actual needs: how many employees, UK-only or international, any CIS requirements, do you already use accounting software that has a payroll add-on? Use the comparison above to shortlist two or three options that match your budget and requirements. Take advantage of free trials — most providers offer them. Run a test payroll cycle before committing. Check that the software is on the GOV.UK list of HMRC-recognised payroll providers. Set up and test before your first real pay run, and run at least one parallel cycle if you're switching from another system.Payroll doesn't have to be complicated. The right software, set up properly, turns it from a monthly headache into a ten-minute task. Take your time choosing, get the fundamentals right, and you'll wonder why you ever stressed about it.Need more help getting your business off the ground?

For most small UK businesses, Sage Payroll (from £20/month for up to 10 employees) offers the best combination of HMRC compliance, features, and reliability without requiring additional accounting software. If you're already using Xero or QuickBooks for accounting, their built-in payroll modules are the most convenient choice. For micro-businesses on a tight budget, Moneysoft (£90/year) or the free tier of Employment Hero are strong starting points.Is there free payroll software that's HMRC compliant? Yes. HMRC's own Basic PAYE Tools is free and handles RTI submissions for businesses with fewer than 10 employees. Employment Hero offers a free tier that includes cloud-based payroll and basic HR features. Both are on the GOV.UK list of recognised payroll software.How much does payroll software cost for a small business? Costs range from free (HMRC Basic PAYE Tools, Employment Hero free tier) to approximately £90–£400 per year for the most popular paid platforms (Moneysoft, BrightPay, Sage, Xero, QuickBooks). International payroll platforms like Deel are significantly more expensive, starting at around $29 per employee per month.What are the employer NIC rates for 2026/27? The employer NIC rate is 15% (increased from 13.8% in April 2025). Employer NICs apply on earnings above the Secondary Threshold of £5,000 per year (£96 per week). The Employment Allowance of £10,500 is available to eligible employers to offset their NIC liability.When is the best time to switch payroll software? The start of a new tax year (6 April) is the cleanest switching point — no mid-year employee data to transfer and no partial-year reconciliation. If you need to switch mid-year, allow 4–6 weeks for setup and run at least one parallel pay period in both systems to verify the new software is calculating correctly.Do I need payroll software if I only have one employee? Yes, if that employee is paid through PAYE. All UK employers must submit RTI to HMRC on or before each payday, regardless of how many employees they have. HMRC's free Basic PAYE Tools is designed exactly for this scenario.What is mandatory payrolling of benefits in kind? From April 2027, most UK employers will be required to report benefits in kind (company cars, private medical insurance, etc.) through their payroll software in real time, rather than reporting them annually on P11D forms after the tax year ends. If you're choosing payroll software now, check that it supports benefit-in-kind payrolling — you'll need this capability within a year.What happens if I submit RTI late? HMRC issues automatic penalties for late Full Payment Submissions. Penalties start at £100 per month for businesses with 1–9 employees, rising to £400 per month for those with 250+ employees. The three most common penalty triggers are late RTI submissions, missed auto-enrolment duties, and incorrect NIC calculations.Last updated: May 2026. Pricing verified against provider websites and independent comparison sources (WhichPayroll, Small Business UK, ObvioTech, ExpertSure) in March–May 2026. All software listed is on the GOV.UK recognised list of HMRC-compatible payroll providers.
