What to look for in payroll software UK?

The UK payroll software market has never been more competitive. Every platform now offers HMRC Real Time Information (RTI) submissions as standard, but the differences in usability, integration depth and price are significant. Before comparing specific platforms, it helps to understand what actually matters for your situation.

HMRC compliance is non-negotiable — any software you choose must handle RTI submissions automatically, calculate PAYE and National Insurance correctly and manage pension auto-enrolment. Beyond compliance, the key differentiators are how much manual work the software eliminates, how well it integrates with your accounting software and whether the pricing scales reasonably as you grow.

Key features to look for

HMRC RTI submissions — automatic, every pay run
Auto-enrolment pension management — handles staging dates and contributions
Integration with your accounting software (Xero, QuickBooks, Sage)
Employee self-service — payslips accessible without chasing HR
HMRC Basic PAYE Tools alternative — proper software vs free government tool
CIS (Construction Industry Scheme) support if relevant
Multiple pay frequencies — weekly, fortnightly, monthly

What is the best payroll software for small businesses in the UK in 2026?

Sage Payroll remains the most widely used payroll solution for UK small businesses in 2026. Its longevity in the UK market means deep HMRC integration, reliable compliance updates and a support team that understands UK-specific requirements. Pricing starts from around £8 per month for up to 5 employees, scaling to £20–£40 per month for growing teams.

BrightPay has become the standout challenger for small businesses — particularly those who find Sage's interface dated. BrightPay offers a genuinely modern experience, excellent auto-enrolment handling and a price point that undercuts Sage significantly. The annual licence model rather than monthly subscription suits businesses that prefer predictable costs.

Xero Payroll is the natural choice if you're already using Xero for accounting. The seamless integration eliminates manual journal entries and the interface is consistent with the rest of the Xero ecosystem. It's not the cheapest standalone payroll option, but the time saved on reconciliation makes it excellent value for existing Xero users.

"The best payroll software is the one your team will actually use correctly. A cheaper tool that gets used wrong costs far more than a premium tool used right."

Best payroll software for growing UK teams

As businesses grow beyond 10–15 employees, payroll software requirements change significantly. You need more sophisticated reporting, HR integration, expense management and ideally a self-service portal that reduces payroll queries to your accounts team.

Moorepay and MHR iTrent lead the mid-market with comprehensive HR and payroll integration. Ciphr is another strong option for businesses that want payroll as part of a broader people management platform. These solutions are substantially more expensive — typically £50–£200 per month depending on headcount — but the reduction in admin overhead justifies the cost at scale.

QuickBooks Payroll occupies an interesting position — strong enough for growing businesses, familiar enough for accountants, and competitively priced compared to enterprise alternatives. If your accountant uses QuickBooks, this is often the path of least resistance.

Free payroll software UK — what's actually available

HMRC's own Basic PAYE Tools is free and handles RTI submissions for businesses with fewer than 10 employees. It is functional but basic — no payslip generation, no integration with accounting software and a UI that hasn't changed significantly in years. For a business processing payroll monthly with a small team, it works. For anything more complex, it quickly becomes a limitation.

Payroll by Wave and Gusto offer free tiers with basic functionality. Moneysoft Payroll Manager offers a genuinely capable free version for businesses with up to 10 employees — it's widely used by sole traders and micro businesses as a step up from HMRC Basic PAYE Tools without the cost commitment of commercial software.

Buying Guide

How to choose — key decisions explained

Employee count

Under 5 employees — HMRC Basic PAYE Tools or Moneysoft free tier is adequate. 5–15 employees — BrightPay or Sage Payroll. 15–50 employees — Xero Payroll or QuickBooks Payroll. 50+ employees — consider dedicated HR/payroll platforms.

Accounting integration

If you use Xero, Xero Payroll is the simplest choice. QuickBooks users should consider QuickBooks Payroll. Sage accounting users naturally fit Sage Payroll. Mixed or no accounting software — BrightPay offers the best standalone option.

CIS requirements

If you operate in construction and need CIS deductions, Sage Payroll and Xero both handle this well. BrightPay also offers CIS support. Not all platforms handle CIS — check before committing.

Budget

Free — HMRC Basic PAYE Tools or Moneysoft. Under £15/month — BrightPay or Sage entry tier. £15–40/month — Xero Payroll or QuickBooks Payroll. £40+/month — mid-market HR/payroll platforms.

FAQs

Frequently asked questions

You are legally required to submit payroll information to HMRC in real time via RTI. You can do this using HMRC's free Basic PAYE Tools or any HMRC-recognised payroll software. The software itself is not a legal requirement — accurate and timely RTI submissions are.

HMRC Basic PAYE Tools is free and handles RTI for up to 10 employees. Moneysoft Payroll Manager also offers a capable free version for small teams. For anything beyond basic payroll processing, paid software typically pays for itself quickly in time saved.

Most commercial UK payroll software handles auto-enrolment pension management, including assessing employee eligibility, calculating contributions and communicating with pension providers. HMRC Basic PAYE Tools does not handle auto-enrolment — you would need a separate solution.

Entry-level payroll software starts from around £5–10 per month for very small teams. Mid-range options for growing businesses typically cost £20–60 per month. Enterprise HR and payroll platforms for larger organisations are priced on headcount, often £5–10 per employee per month.
