Outsource Payroll Ireland 2026 — When and How to Outsource Payroll

Payroll outsourcing in Ireland means contracting a third party — an accountancy practice or specialist payroll company — to process your payroll on your behalf. You provide the inputs (hours worked, starters, leavers, any pay changes), and the outsourced provider handles everything else: the calculations, Revenue submissions, payslips, and now auto-enrolment.

With PAYE Modernisation, Enhanced Reporting Requirements, and auto-enrolment all adding complexity to the Irish payroll run, outsourcing has become an increasingly attractive option for Irish businesses that don’t want to develop in-house payroll expertise.

What Payroll Outsourcing in Ireland Covers

A full-service Irish payroll outsourcing arrangement typically includes:

Payroll calculations

• PAYE income tax using Revenue-issued credits and cut-off points
• PRSI at the correct class for each employee
• USC at current tiered rates
• Benefit in Kind (BIK) calculations for company cars, health insurance, gym memberships
• Holiday pay and statutory entitlements
• Statutory sick pay under the Sick Leave Act 2022

Revenue compliance

• PAYE Modernisation: real-time Payroll Submission Requests (PSRs) to Revenue ROS after every payroll run
• Enhanced Reporting Requirements (ERR): reporting travel and subsistence, remote working allowances, small benefit exemptions
• P60s to all employees in January
• P45s for leavers

Auto-enrolment (from 2025)

Banking (where included)

• SEPA XML payment file generation for bulk payroll payments through Irish banks

What Payroll Outsourcing Costs in Ireland

Irish payroll outsourcing is typically priced per employee per month or as a flat monthly fee:

Additional factors that increase cost:

• Weekly payroll vs monthly — more frequent processing means higher fees
• Variable hours — businesses with irregular hours each period cost more to process than fixed-salary businesses
• Complexity — businesses with BIK, commission, or complex shift patterns cost more
• Auto-enrolment — some providers charge a supplement for auto-enrolment administration
• New starters and leavers — high-turnover businesses often pay a per-event fee for each new starter or leaver

Outsourcing vs Running Payroll In-House

For businesses under 15 employees with a stable, predictable payroll, running payroll in-house with BrightPay, Thesaurus, or Collsoft is significantly cheaper. For larger businesses, or those where the payroll person is also doing three other jobs and payroll errors are a recurring issue, outsourcing often makes financial sense when the time cost is properly accounted for.

How to Choose a Payroll Outsourcing Provider in Ireland

1. Ask your accountant first
Many Irish accountancy practices offer payroll processing alongside their bookkeeping and accounts work. If you already have a trusted accountant, asking them to handle payroll keeps everything in one place and simplifies year-end accounts. Ask about their auto-enrolment capabilities and whether payroll is included in your current fee or charged separately.

2. Confirm compliance capabilities
Ask explicitly:

• Are you set up for PAYE Modernisation real-time submissions?
• Do you handle ERR reporting?
• Are you processing auto-enrolment from 2025?
• What payroll software do you use?

A payroll provider using outdated software is a compliance risk. Most established Irish practices use BrightPay or Thesaurus.

3. Understand the process for submitting inputs
How do you send hours, starters, and leavers each period? The best providers use a simple, structured online portal or form. Avoid providers that rely entirely on email threads — it creates version control problems and makes disputes difficult to resolve.

4. Confirm payslip delivery
How are payslips delivered to employees? Email directly from the bureau? Via a self-service portal? Employees increasingly expect to access their own payslips on their phone without having to ask HR.

5. Check turnaround times
For monthly payroll, most providers can turn around in 24–48 hours with reasonable inputs lead time. For weekly payroll, shorter turnarounds are needed. Confirm what lead time they need and whether rush processing is available.

6. Verify liability and insurance
If the bureau makes a payroll error resulting in underpayment to an employee or an incorrect Revenue submission, what happens? Reputable providers carry professional indemnity insurance and will correct errors at their own cost. Confirm this in writing.

Auto-Enrolment and Outsourced Payroll

Auto-enrolment adds a new compliance layer from 2025. If you outsource payroll, your bureau must:

• Check employee eligibility on an ongoing basis as new staff join or existing staff change hours
• Calculate and deduct employee contributions
• Add employer contributions
• Generate and submit NTMA contribution files each period

Ask your payroll provider explicitly whether auto-enrolment is included in your existing fee or whether there will be an additional charge. Many providers are absorbing it; some are adding a supplement.

Verdict

Outsourcing payroll makes sense for Irish businesses that want someone else to be responsible for compliance — PAYE Modernisation, ERR, auto-enrolment — and are willing to pay the premium over running payroll software in-house.

For businesses with fewer than 15 employees and a stable payroll, the cost difference between outsourcing and running your own payroll software is significant enough that it’s worth developing the in-house capability. For larger, more complex businesses, or those where the person who “does payroll” is already stretched too thin, outsourcing the whole function is a practical and increasingly common choice.

Frequently Asked Questions

What does payroll outsourcing cost in Ireland? Typically €50–€100/month for small businesses (1–5 employees), scaling to €400–€800/month for 30–100 employees. Prices vary by pay frequency, complexity, and provider.

What’s the difference between a payroll bureau and payroll outsourcing? The terms are largely interchangeable in Ireland. A payroll bureau is a provider that processes your payroll on your behalf — that’s what payroll outsourcing means in practice.

Can my accountant handle payroll outsourcing? Many Irish accountancy practices offer payroll bureau services. Ask your accountant — combining payroll with accounts work simplifies your year-end process.

Does an outsourced payroll provider handle auto-enrolment? Most established Irish payroll bureaus handle auto-enrolment from 2025. Confirm this explicitly and ask whether it’s included in your current fee.

What are the risks of outsourcing payroll? Key risks: errors by the provider (mitigated by choosing a provider with professional indemnity insurance), loss of in-house knowledge (mitigated by keeping records and understanding the basics), and slower response to urgent changes (mitigated by clear SLAs). These risks are manageable with the right provider.

Is payroll outsourcing suitable for a small Irish business? For businesses with under 10 employees and a stable payroll, running payroll in-house with BrightPay or Thesaurus is usually cheaper. Outsourcing becomes more attractive as complexity and employee numbers increase.
