Payroll Migration: Switching Payroll Provider in Ireland

You do not have to wait until the end of the tax year to change payroll provider. A mid-year switch can be handled cleanly when the existing payroll data, Revenue access, year-to-date figures and cutover date are reconciled before the first live pay run.

The aim is continuity, not a restart. If the legal employer is unchanged, the migration normally continues under the employer’s existing PAYE registration while the people, systems or agent permissions used to process payroll change. Payrollcompany.ie manages that transition as a structured handover, then moves you into the ongoing process of running it.

A structured handover, not a software import

Who it’s for

Who This Payroll Service Is For

A payroll migration can make sense if you are:

Switching bureau or provider

Changing from one payroll bureau or outsourced payroll provider to another.

Moving away from an accountant

You want a specialist payroll service rather than payroll bundled into general accountancy work.

Leaving an in-house or DIY process

Taking payroll out of an internal or do-it-yourself process.

Moving off spreadsheets

Moving from spreadsheets or a largely manual workflow into a managed service.

Changing software and provider together

Changing payroll software while also changing the person or provider responsible for running it.

Moving a book from a practice

Moving a payroll book from an accountancy practice to a white-label payroll partner.

Accountancy practices moving client payrolls can also use the same migration principles. Our For Accountants service section explains the separate white-label workflow and Revenue relationship in more detail.

The legal picture

What Stays the Same When You Change Provider

Changing payroll provider is not the same as changing employer. Your employees do not leave one employment and start another merely because a different provider processes the pay run.

Registration follows the employer, not the provider

Where the legal employer remains the same, the existing employer PAYE registration normally remains the registration used for payroll. Revenue treats employer registration as an obligation of the employer, while a new registration question can arise where there is a genuine change of employer or ownership.

Revenue ties the registration to the employer, and its change-of-ownership process deals separately with situations where a new employer takes over a business.

The employee’s existing Revenue employment record and payroll submissions also remain in Revenue’s systems. What does need to move is the payroll information required to continue calculating and reporting the same employment correctly in the new payroll system.

Opening balances

Year-to-Date Figures Do Not Rebuild Themselves

One of the most important migration steps is carrying forward accurate year-to-date payroll balances. The latest Revenue Payroll Notification (RPN) gives the current tax credits, Income Tax and USC cut-off points and other Revenue instructions, but it is not a replacement for a complete payroll handover.

Before every live payroll, Revenue requires the latest RPN to be requested and used. Our Revenue Payroll Notification guide explains that process in detail, while the migration itself also needs opening balances from the existing payroll records.

Depending on the payroll, those balances can include:

If those figures are wrong at cutover, the new payroll may produce incorrect cumulative results, inaccurate year-to-date payslips or confusing payroll reports even when the current RPN itself is correct.

Revenue access

Revenue Access Needs Its Own Cutover Plan

A provider switch may require a change to Revenue access, but the exact setup depends on how the outgoing and incoming providers are authorised.

Where the new provider will act as a Revenue agent, Revenue’s current agent e-linking process allows an online customer to approve or reject the agent-link request in ROS or myAccount.

The old provider’s access should also be dealt with deliberately. Revenue’s current agent guidance says that when an agent ceases to represent a client, Revenue should be notified so the agent can be removed from the relevant client listing.

Previous Payroll Submissions Can Need Additional Access

An agent can only view and amend payroll submissions filed under that agent’s own certificate. If a new agent needs to view or amend submissions filed by a previous agent or directly by the client, the employer may need to provide an appropriate ROS sub-certificate.

That makes access planning part of the migration rather than an afterthought. A new provider should not assume that being linked as the current payroll agent automatically gives visibility of every historical submission made by someone else.

Do Not Hand Over the Employer's ROS Login

A payroll migration should use the appropriate Revenue authorisation and user-permission route rather than sharing the employer’s administrator login details. Revenue provides agent links and employer sub-user certificates so access can be controlled without passing around the employer’s own ROS credentials.

Before cutover

What We Review Before Cutover

The handover starts with the payroll as it actually operates today. We review the records, the Revenue position and the recurring pay setup before deciding what should be carried into the new system.

Process

How a Payroll Migration Works

1

Agree the scope

We confirm which payrolls are moving, their pay frequencies, the employees included and the ongoing service required.

2

Set the cutover date

The date is chosen around your actual payroll calendar. It can be mid-year and does not need to be 1 January.

3

Collect the handover records

We obtain the employee master data, year-to-date reports, recurring pay items, deduction records and other agreed payroll information.

4

Confirm Revenue access

Where an agent link or employer sub-user access is needed, the appropriate Revenue route is put in place before the first live submission.

5

Reconcile the opening balances

 We compare the figures being loaded into the new payroll with the agreed source records and the Revenue information available for the employer.

6

Resolve known discrepancies

If an earlier payroll submission is wrong, the correction is dealt with through the appropriate payroll or ROS process rather than silently carrying the error forward.

7

Retrieve current RPNs

The latest RPN is requested for every employee being paid in the first live run.

8

Run payroll and review control totals

Gross pay, deductions, employee counts and unusual movements are reviewed before approval.

9

Make the live payroll submission

Payroll information is reported to Revenue on or before the pay date under the employer’s correct registration.

10

Close the old access route

Once the outgoing provider has completed the agreed handover and is no longer authorised to act, unnecessary Revenue and data access should be removed.

Data quality

Corrections Discovered During Migration

A migration sometimes exposes issues that were already present, such as a duplicated employee, an incorrect year-to-date balance, a missed taxable benefit or a payroll submission that does not match the payroll records.

Revenue allows payroll submissions to be corrected through payroll software or ROS, as explained in its payroll corrections guidance. The right correction depends on what was wrong and when it occurred.

We don't paper over the difference

We don’t simply create an off-payroll balancing figure to make the new system agree. Where a discrepancy affects Revenue reporting, the payroll records and Revenue submission need to be aligned through the proper correction route.

No bureau required

Switching From an In-House or DIY Payroll

A migration does not need an outgoing payroll bureau. If you have been running payroll internally, the same controls still apply: confirm the employer registration, review employee records, reconcile year-to-date figures and identify anything that needs to be corrected before the next live pay run.

DIY migrations often need more attention to process as well as data. The new setup should define who sends payroll changes, the cut-off for inputs, who approves the run and how employee queries are handled. That prevents the informal habits of the old process being recreated in the new one.

Payroll Data Needs a Controlled Handover

Payroll files contain detailed employee personal and financial information. The Data Protection Commission specifically uses outsourced payroll as an example of a controller-processor relationship. The employer is the data controller and the payroll company is the data processor in that arrangement.

The migration should therefore use an agreed secure transfer method and a written processing agreement that reflects the payroll work being performed. Access should be limited to the people who need it for the handover and ongoing service.

Getting started

What We Need From You

You do not need to rebuild the payroll from memory. We start with the records you already have and identify any missing information during the review.

Your employer PAYE registration details.
Current payroll reports and employee master data.

Year-to-date payroll totals.

Details of recurring pay, benefits and deductions.

Pension and MyFutureFund information where relevant.

Details of any unresolved payroll corrections.

Your payroll calendar and approval contacts.

Contact details for the outgoing provider if you authorise us to coordinate the handover directly.

After cutover

What Changes After the Migration

Once the cutover is complete, payroll moves from a one-off transition project into a repeatable pay-run process. The agreed inputs come in by the payroll cut-off, the latest RPNs are retrieved, payroll is calculated and reviewed, the Revenue submission is made on or before the pay date, and payslips and reports are issued through the agreed workflow.

Employees may notice a different payslip layout or a new payroll contact, but a provider change should not be used to reset their employment history, tax-year payroll totals or existing statutory records.

What goes wrong

Common Payroll Migration Problems

Choosing a cutover date before the data is ready.

A convenient date is not useful if the opening balances, employee records or Revenue access are still incomplete.

Assuming the new agent can see everything the old agent filed.

Revenue restricts agent access to submissions filed under that agent’s certificate unless the employer provides the appropriate additional access.

Loading totals without reconciling them.

Opening balances should agree to the source payroll records and the Revenue information available to the employer before they are relied on.

Sharing administrator credentials for convenience.

Use the proper agent or sub-user access route rather than circulating the employer’s ROS administrator credentials.

Treating the RPN as the whole handover.

The RPN provides current Revenue instructions, but the new payroll still needs accurate year-to-date and recurring payroll data.

Leaving old Revenue access open indefinitely.

Once the old provider no longer represents the employer, its agent relationship or other unnecessary access should be removed.

Carrying a known error into the new system.

If an earlier payroll or Revenue submission is wrong, deal with the correction as part of the transition instead of embedding it in the new opening balances.

Changing too many things in the first live run.

Where practical, preserve established pay frequencies and pay elements through cutover, then make separate planned changes once the new payroll is stable.

Frequently asked questions

Common questions about payroll migration

Yes. A provider change can be made during the tax year. The key is to reconcile year-to-date payroll information, arrange the correct Revenue access and choose a cutover date that fits the real pay cycle.

Not simply because you appoint a different payroll provider. If the legal employer remains the same, payroll normally continues under the existing employer PAYE registration. A new registration question can arise where there is a genuine change of employer or business ownership.

No. The new provider requests the latest RPN from Revenue for the existing employment. The payroll system also needs the correct year-to-date opening balances so the employee’s ongoing payroll record is not treated as if the tax year started again.

Not automatically. Revenue says an agent can view and amend submissions filed under that agent’s certificate. Access to submissions filed by a previous agent or directly by the employer can require an appropriate employer sub-certificate.

No. Revenue access should be arranged through the appropriate agent relationship or controlled sub-user certificate rather than sharing the employer’s administrator credentials.

If the outgoing provider is recorded as a Revenue agent and no longer represents you, the agent relationship should be removed through the appropriate Revenue process once the handover is complete.

Revenue allows payroll submissions to be corrected through payroll software or ROS. The migration review should identify the issue and determine the proper correction instead of hiding it inside a balancing adjustment.

No. The cutover should be chosen around your payroll timetable and readiness of the migration data. Year-end can be convenient, but it is not the only practical point to change provider.

Yes, where those pay frequencies form part of the agreed payroll scope. The migration maps each payroll calendar and cut-off so the first live runs are sequenced correctly.

Yes. We review the existing records, Revenue registration, employee data and year-to-date figures in the same way, then agree the cutover and ongoing payroll process.

Yes, if you authorise us to do so. Direct coordination can make it easier to obtain the agreed payroll reports, employee data and outstanding-issue list, while you remain in control of the relationship and access permissions.

It depends on the number of employees, pay frequencies, payroll complexity, data quality and Revenue access required. We do not use a fixed timeframe unless it has been agreed for your specific migration.
