Best Payroll Software for the UK in 2026

Sage Payroll (part of the Sage HR suite) is one of the UK's most established payroll platforms, used by hundreds of thousands of British businesses. The software handles PAYE income tax calculations across all tax codes (including emergency codes, Week 1/Month 1 basis), National Insurance contributions for both employee and employer at the correct NI categories (A, B, C, H, J, M, V, X, Z), and RTI submissions directly to HMRC via Full Payment Submission (FPS) and Employer Payment Summary (EPS).

Sage Payroll manages pension auto-enrolment with qualifying scheme enrollment, contribution calculations, and the postponement and opt-out workflows that The Pensions Regulator requires. The platform handles all statutory payments — SSP, SMP, SPP, SSPP, and ShPP — with automatic entitlement calculations, and generates P45/P60/P11D documents at the correct filing points.

Sage is best suited to UK companies with 5–500 employees that want a locally supported, HMRC-recognised payroll product from a vendor with decades of UK compliance expertise. The platform integrates with Sage Accounting, making it a natural choice for businesses already using Sage for bookkeeping.

Moorepay is a UK payroll bureau and software provider that offers both self-service payroll software and fully managed payroll processing for British employers. The managed service model means Moorepay's team handles RTI submissions, PAYE reconciliation, and HMRC queries on the client's behalf — reducing the in-house payroll expertise required.

Moorepay's platform handles the full UK payroll compliance stack: PAYE calculations, NI contributions across categories, pension auto-enrolment including re-enrolment cycles, statutory payments, student loan deductions (Plan 1, Plan 2, Plan 4, and Postgraduate Loan), and year-end P60 production. The platform also includes HR modules for absence management and employment contracts.

Moorepay suits UK companies with 50–5,000 employees that want to outsource payroll risk to a specialist bureau rather than run it in-house. It is particularly popular among companies without a dedicated payroll manager who want compliance guaranteed by a specialist team.

IRIS Payroll is the UK's leading payroll software for accountants and payroll bureaus, used by over 11,000 accountancy practices across Britain. The software handles PAYE, NIC, RTI submissions, auto-enrolment, and all statutory payments for unlimited client companies from a single interface — making it the standard choice for accountants who process payroll for multiple businesses.

IRIS integrates directly with HMRC via RTI and supports the full range of UK payroll complexity: multiple pay frequencies (weekly, fortnightly, four-weekly, monthly) within the same client portfolio, PAYE Settlement Agreements (PSA), Construction Industry Scheme (CIS) deductions, and IR35 off-payroll working compliance. The software also generates client-ready payroll reports and employee payslips in branded formats.

IRIS Payroll is best suited to accountants running payroll bureaus and companies that want to outsource payroll processing to an accountant using industry-standard software. In-house HR teams at individual companies may find bureau-focused workflow assumptions less intuitive than HR-facing tools like Sage or BrightPay.

Deel offers EOR services in the UK, acting as the legal employer for companies that want to hire British workers without setting up a UK limited company. Deel handles PAYE registration, RTI submissions to HMRC, employer and employee NIC calculations, pension auto-enrolment with a qualifying scheme, and GBP salary payments.

For companies with an existing UK entity, Deel's global payroll product integrates with local UK payroll bureaus to process payroll while providing a consolidated multi-country dashboard. The platform handles P45/P60 generation and year-end P11D reporting for benefits in kind.

Rippling processes UK payroll natively through its global payroll engine, handling PAYE calculations, RTI submissions directly to HMRC, employer NIC at 13.8%, employee NIC based on the current thresholds, and pension auto-enrolment. US companies with a UK entity can manage both payrolls from one platform with automated GBP/USD reporting.

The platform handles Scottish income tax rates for employees with S tax codes, student loan deductions across Plan 1, Plan 2, Plan 4, and postgraduate loans, and statutory sick pay and statutory maternity/paternity pay calculations. Rippling also supports salary sacrifice pension arrangements and childcare voucher schemes.

ADP is one of the largest payroll processors in the UK, serving enterprises with hundreds or thousands of employees. The platform handles every aspect of UK payroll compliance: PAYE/RTI, employer and employee NIC across all categories, pension auto-enrolment with multiple scheme providers, statutory payments (SSP, SMP, SPP, ShPP, SAP), student loan deductions, and attachment of earnings orders.

ADP's UK payroll runs on dedicated local infrastructure with deep compliance logic built over decades. The platform handles complex scenarios including directors' NIC calculations (annual earnings period method vs cumulative method), IR35 off-payroll working rules for contractors, and Construction Industry Scheme (CIS) deductions.

Paychex provides managed payroll services in the UK through its local operations, handling PAYE/RTI submissions, NIC calculations, pension auto-enrolment, and year-end compliance. Mid-market companies that want payroll processed by specialists rather than running software in-house can use Paychex's bureau service.

The managed service model means Paychex's UK payroll team handles the processing, HMRC communications, and compliance filings, while employers provide the input data (hours, salary changes, new hires, leavers). This approach suits companies that lack dedicated payroll staff.

Workday's global payroll connectors integrate with UK payroll processors to provide enterprise-level reporting and workforce analytics alongside local compliance. Organizations running Workday HCM globally can add UK payroll through certified partners without building a separate data pipeline.

The platform provides consolidated payroll cost reporting across the UK and other countries, workforce planning tools for UK headcount, and compensation analytics in GBP. Actual UK payroll processing — PAYE calculations, RTI submissions, pension enrolment — is handled by the certified local partner.

ADP Workforce Now extends to UK payroll through ADP's local processing infrastructure, giving mid-market companies a unified HR and payroll platform across the US and UK. The system handles PAYE/RTI, NIC calculations, pension auto-enrolment, and statutory pay through ADP's established UK payroll engine.

The platform supports the full UK payroll cycle including P45/P60 generation, student loan deductions, and year-end reporting. For companies with 50-500 UK employees, Workforce Now provides a balance between enterprise capabilities and mid-market pricing.

Workday HCM provides the human capital management layer that feeds employee data into UK payroll processing through certified partners. Organizations standardized on Workday HCM get automated data synchronization between core HR records and the UK payroll engine, eliminating manual reconciliation.

The platform handles UK compensation structures, benefits management, and absence tracking that directly inform payroll calculations. For enterprises already using Workday, this is the most efficient path to UK payroll integration even though the actual payroll processing is outsourced to a certified partner.

QuickBooks Payroll in the UK handles PAYE calculations, RTI submissions to HMRC, employer and employee NIC, and basic pension auto-enrolment. For small businesses already using QuickBooks for accounting, the payroll add-on provides an integrated solution that syncs payroll journal entries directly to the general ledger.

The platform supports up to a few hundred employees and handles the core UK payroll requirements: tax code processing, student loan deductions, statutory sick pay, and statutory maternity pay. QuickBooks generates P45s for leavers, P60s at year-end, and files FPS and EPS returns directly with HMRC.

OnPay provides a clean, straightforward payroll interface that handles core UK payroll requirements for small businesses. The platform processes PAYE calculations, files RTI returns with HMRC, manages pension auto-enrolment, and handles basic statutory pay calculations without the complexity of enterprise platforms.

For small UK businesses with 5-50 employees that want reliable payroll processing without paying for features they will never use, OnPay offers a simplified alternative to feature-heavy platforms. The trade-off is limited support for complex UK payroll scenarios.
