Employees working abroad: Irish employer duties

Mellow Editorial·5 min read

Employees working abroad temporarily or permanently create real obligations for Irish employers — on tax, social insurance, employment law and reporting — that cannot be ignored just because the employee has left the country.

What triggers employer duties when an employee works abroad

The starting point is whether the employee remains on the Irish payroll. If they do, Revenue's default position is that Irish PAYE, USC and PRSI still apply, regardless of where the work is physically performed. The employee's physical location does not automatically end your obligations as the employer of record.

The two questions that shape everything else are: how long is the employee abroad, and where are they working? A week at a client site in Amsterdam is very different from a year working remotely from Lisbon. Duration and destination together determine whether you face a temporary inconvenience or a set of ongoing compliance obligations in a second jurisdiction.

Tax residency and the risk of a second payroll obligation

Ireland taxes residents on worldwide income. An employee who stays tax-resident in Ireland — broadly, someone present in Ireland for 183 days or more in a tax year, or 280 days across two consecutive years — continues to be subject to Irish income tax at 20% up to the standard rate band (around €44,000 for a single person in 2026) and 40% above that, plus USC and PRSI in the usual way.

If the employee breaks Irish tax residency, the picture changes. They may become tax-resident in the host country, which can require you to register as an employer there and operate that country's payroll. Running two payrolls simultaneously is possible but administratively demanding, and the rules differ sharply between countries.

Ireland has double taxation agreements (DTAs) with a large number of countries. These agreements determine which country has the primary right to tax employment income and can prevent the employee being taxed twice on the same earnings. As the employer, you need to know whether a DTA applies and what it says, because it affects how you operate withholding tax. A tax advisor with international experience is essential here — the treaty provisions are specific and sometimes counterintuitive.

Social insurance: where things get complicated quickly

PRSI does not follow the same rules as income tax. Social insurance is governed separately, and EU regulations coordinate which country's social security system applies when an employee moves within the EU or EEA.

For moves within the EU or EEA, an employee can often remain in the Irish social insurance system (paying employee PRSI at approximately 4.1% and triggering employer contributions at approximately 11.15%) using an A1 certificate issued by the Department of Social Protection. This is typically available for postings of up to 24 months. Without an A1, the host country's social security system may apply, and you may need to register and contribute there instead.

For moves outside the EU or EEA, the position depends on whether Ireland has a bilateral social security agreement with the destination country. Where no agreement exists, there is a real risk of double contributions — paying into both systems simultaneously. That is expensive and worth resolving before the employee travels.

Employment law and the employment contract

Irish employment legislation — including the statutory entitlement to four working weeks of annual leave — generally continues to apply to employees who remain employed under an Irish contract, even while abroad. However, the host country may impose its own mandatory employment protections on top of, or instead of, Irish law. Many EU countries apply local law to workers posted there, even temporarily.

Updating or supplementing the employment contract before the employee travels is good practice. The contract should be clear on: which law governs the relationship, where disputes are resolved, how expenses and allowances are handled, and what happens if the arrangement changes. Leaving this implicit creates ambiguity that can become expensive to resolve.

Permanent establishment risk

This is the obligation that catches employers off guard most often. If an employee working abroad has authority to conclude contracts on behalf of the Irish company, or operates from a fixed place of business in the host country, the company may inadvertently create a taxable presence — a "permanent establishment" — in that country. That means corporate tax registration and filing obligations there, not just payroll.

The threshold for what constitutes a permanent establishment varies by country and by the relevant tax treaty. A senior salesperson closing deals from a home office in Spain is a different risk profile from a developer working remotely on internal systems. The distinction matters and is worth taking specialist advice on before the arrangement begins, not after Revenue or the foreign tax authority raises a query.

Reporting to Revenue

Irish payroll reporting operates in real time: submissions must be made to Revenue via ROS on or before each payday. If the employee remains on the Irish payroll while abroad, this obligation continues unchanged. If their status changes — for example, they become non-resident and are removed from the Irish payroll — that change should be reflected accurately and promptly in your records and submissions.
