Employer registration for PAYE and PRSI — mandatory before first payment
Any person or entity employing workers in Ireland must register as an employer with the Irish Revenue Commissioners before making any payment to an employee. This registration creates an employer record for both Pay As You Earn (PAYE) income tax withholding and Pay Related Social Insurance (PRSI) contributions, which are collected together under a unified system.
Statutory obligation and timing
The obligation to operate PAYE is imposed by the Taxes Consolidation Act 1997, Part 42. PRSI is collected alongside income tax under the PAYE system; employers are legally obliged to ensure that the correct amount of PRSI is deducted from employees and to remit it, together with the employer's own PRSI liability, to Revenue. Registration must be completed before making any payments to an employee.
Registration mechanism — Revenue Online Service (ROS)
Employers register through Revenue's eRegistration facility, accessed via the Revenue Online Service (ROS) for companies and agents, or via myAccount for individuals. The system issues an Employer Registration Number (ERN), sometimes displayed in formats such as 1234567T, which anchors all subsequent payroll submissions. Mandatory e-filers—most employers operating payroll—are required to register through ROS.
Non-resident companies establishing payroll in Ireland for the first time use form TR2(FT) if registering on paper; Irish companies without an agent use TR2; sole traders and partnerships use TR1 or TR1(FT) for non-residents. Employers already registered for income tax or corporation tax but adding their first employee use form PREM Reg. In practice, online registration via ROS is faster, cheaper, and the Revenue-preferred route.
Real-time payroll reporting under PAYE Modernisation
Since 1 January 2019, Ireland operates a real-time PAYE reporting system. Employers must submit payroll data to Revenue on or before each pay date, including gross pay, income tax withheld, PRSI deducted (employee share), PRSI owed (employer share), Universal Social Charge (USC), and the employee's Personal Public Service Number (PPSN). Revenue issues a Revenue Payroll Notification (RPN) for each employee, which the employer must request and use to calculate the correct withholding; the RPN replaces the old static tax-credit certificates and updates dynamically.
The employer record links every payroll submission back to the registered entity. Revenue can automatically register an employer if it believes registration is required but has not occurred; a formal notice of registration is issued, and the employer has 30 days to appeal to the Tax Appeals Commission.
PRSI obligations run in parallel
PRSI contributions go to the Social Insurance Fund, which funds social welfare benefits and pensions. Employers of workers aged 16 and over must record and pay PRSI for employees; most employees fall under Class A PRSI, which covers both employee and employer contributions plus a 1% National Training Fund Levy included in the employer share. The class of PRSI is determined by the nature of the employment and weekly earnings; PRSI contributions are payable once weekly earnings exceed €352.
Employers are liable for PRSI on the reckonable earnings of the employee (including notional pay). The employer deducts the employee share from gross pay and remits it to Revenue alongside the employer's own contribution. Under the Social Welfare Consolidation Act 2005 (as amended), employers who do not comply with PRSI obligations and are found guilty of an offence can be fined up to €13,000 or imprisoned for up to three years, or both. The collection of PRSI is not statute-barred, so non-compliance can be pursued indefinitely.
Practical implications for foreign employers
A foreign company hiring its first employee in Ireland—whether a locally-hired Irish resident or an intra-company transfer—must establish an Irish employer registration even if the company has no Irish entity. Many foreign employers use an Employer of Record (EOR) to avoid setting up payroll infrastructure; the EOR holds the employer registration and acts as the legal employer for PAYE/PRSI purposes, while the foreign company remains the economic employer. Alternatively, the foreign company can register directly with Revenue, obtain an ERN, implement compliant payroll software (or engage a payroll bureau), and submit real-time returns.
Employers operating a foreign payroll with no access to Irish payroll infrastructure, or employing non-PAYE employees without PAYE exclusion orders, may fall under the PRSI Special Collection System, where PRSI is remitted directly to the Department of Social Protection rather than through Revenue. This is a narrow exception; the default position is registration with Revenue and monthly remittance through the PAYE system.
Permanent establishment (PE) exposure
Hiring an employee resident in Ireland can create Irish permanent establishment (PE) exposure for a foreign company under domestic tax law and double-tax treaties (OECD Model Treaty Article 5). The presence of a dependent agent habitually exercising authority to conclude contracts, or a fixed place of business through which the enterprise's business is wholly or partly carried on, may trigger Irish corporation tax registration and filing obligations separate from the employer PAYE/PRSI registration. The employer registration itself does not create PE, but the underlying employment relationship (especially if the employee conducts sales, signs contracts, or manages operations for the foreign company in Ireland) can. Companies should assess PE risk before hiring, not after the first payroll run.

Mandatory written statement of employment terms — the 5-day core-terms requirement
Every employer in Ireland must provide new employees with a written statement of core terms of employment within five days of the start date, followed by a more comprehensive statement within one month. This two-stage disclosure obligation is imposed by the Terms of Employment (Information) Acts 1994 to 2014 as amended by the Employment (Miscellaneous Provisions) Act 2018, which came into force on 4 March 2019, and further updated by the European Union (Transparent and Predictable Working Conditions) Regulations 2022 (S.I. No. 686/2022), effective 16 December 2022.
The "Day 5" statement — core terms within five days
Within five days of commencement of employment, the employer must furnish a written statement containing the following five core terms:
- Full names of both the employer and the employee;
- Address of the employer;
- Expected duration of the contract (in the case of a temporary contract) or the end date (if a fixed-term contract);
- Rate or method of calculation of pay and the pay reference period (weekly, fortnightly, monthly);
- Number of hours the employer reasonably expects the employee to work per normal working day and per normal working week.
The statement must be in writing, signed and dated by or on behalf of the employer, and transmitted on paper or electronically provided the information is accessible to the employee. The employer must retain a copy throughout the employment and for one year after it ends.
The comprehensive statement — full terms within one month
Within one month of commencement, the employer must provide a comprehensive written statement covering all statutory particulars, including (in addition to the five core terms above):
- The place of work, or if there is no fixed or main place of work, a statement that the employee works at various places or is free to set their own place of work;
- Job title or nature of work;
- Date of commencement of employment;
- Details of any probationary period, including its duration and conditions;
- Any terms or conditions relating to hours of work (including overtime);
- Annual leave and public holiday entitlements;
- Sick leave and sick pay (if any);
- Pension arrangements (if any);
- Period of notice required on each side;
- Details of any collective agreements that directly affect the terms and conditions of employment.
The 2022 Regulations expanded the definition of "contract of employment" to include not only contracts of service and apprenticeship but also any contract under which an individual personally executes work or service for another person, and arrangements with employment agencies where the individual performs work for a client. This brings a broader range of workers within scope.
Requests by existing employees
Existing employees may make a written request to their employer for a "Day 5" statement. Upon receipt of such a request, the employer must issue the statement within two months of the date of the request. Employees who entered a contract of employment before 16 December 2022 may request a new comprehensive statement that includes both the Day 5 core terms and the full statement of terms; employees who started before 16 May 1994 may request a statement covering the new particulars introduced since that date.
Enforcement and penalties
Non-compliance triggers both civil and criminal liability.
An employer who fails to provide the Day 5 statement within one month of commencement commits a criminal offence under the Employment (Miscellaneous Provisions) Act 2018. An employer who deliberately or recklessly provides false or misleading information in the statement also commits an offence. On summary conviction, the employer may be fined up to €5,000 or imprisoned for a term not exceeding 12 months, or both. The Act provides a defence for clerical mistakes or errors made accidentally and in good faith.
In addition to criminal liability, an employee with at least four consecutive weeks' continuous service may refer a complaint to the Workplace Relations Commission (WRC) where the employer has failed to provide the Day 5 statement within five days, failed to provide the comprehensive statement within one month, or provided a statement that is deliberately false or misleading. Where a complaint is upheld, the WRC may award compensation not exceeding four weeks' remuneration—just and equitable in the circumstances. Employees who entered employment before the 2018 Act came into force must have one month's continuous service before they can bring a complaint.
Anti-penalisation protections
The Employment (Miscellaneous Provisions) Act 2018 introduced strong anti-penalisation provisions. An employer may not penalise or threaten to penalise an employee for:
- Invoking any right under the Terms of Employment (Information) Acts;
- Opposing in good faith an action that is unlawful under the Acts (such as refusing to conspire in falsifying contracts);
- Giving evidence in any proceedings under the Acts (for example, acting as a witness for a colleague's WRC case);
- Giving notice of the intention to do any of the above.
"Penalisation" is broadly defined and includes suspension, lay-off, dismissal, demotion, changes to terms and conditions to the employee's detriment, disciplinary action, coercion, and intimidation. An employee who is penalised may bring a separate complaint to the WRC and may be awarded up to four weeks' remuneration.
A WRC Inspector who encounters non-compliance and has reasonable grounds for believing an employer has committed an offence may issue a fixed payment notice as an alternative to prosecution. This administrative penalty is designed to encourage compliance without requiring criminal proceedings.
Practical implications for foreign employers
A foreign company hiring its first employee in Ireland—whether an Irish resident or an intra-company transferee—must comply with the Day 5 and one-month written-statement requirements even if the foreign entity has no Irish registered office. The obligation runs to the legal employer (the entity that pays the employee or, in the case of an EOR arrangement, the entity named as employer).
Many foreign employers find it operationally simpler to engage an Employer of Record (EOR) who takes on the legal employer role, issues compliant contracts, and operates Irish payroll; alternatively, the foreign company can register directly with Revenue, set up compliant HR and payroll infrastructure (or engage an Irish payroll bureau or law firm to draft contracts), and issue the required statements itself. Either way, the five-day clock starts ticking on the employee's actual start date, not on the date payroll is set up or the date the employer entity is incorporated. Delayed compliance—waiting until the end of the first week or the first pay cycle—exposes the employer to both WRC complaints and criminal prosecution.
Ireland's written-statement framework is unusually prescriptive compared to many common-law jurisdictions. The combination of a short initial deadline (five days), detailed mandatory content, a criminal offence for late or false statements, and a one-month service threshold for civil complaints means that first-time employers should prepare template contracts before the first hire, not after. The statement must be tailored to each employee (especially the pay rate, hours, and contract duration), signed by or on behalf of the employer, and delivered within the statutory window. Generic offer letters or email confirmations are insufficient unless they contain all five core terms in a signed, dated written statement.

Permanent establishment (PE) risk — when hiring creates an Irish taxable presence
A foreign company hiring an employee resident in Ireland—or posting an employee to work in Ireland—must assess whether the employment relationship will create an Irish permanent establishment (PE) that triggers Irish corporation tax registration and filing obligations. This is the first question a cross-border employer should answer, before setting up payroll or issuing contracts. The PE determination is separate from the employer's PAYE/PRSI registration duty (which is mandatory for any Irish payroll) but often flows from the same underlying facts: the presence of people and activities in Ireland.
Domestic PE definition — Section 25 TCA 1997 and the branch-or-agency test
Under Irish domestic law, a non-resident company (a company not tax-resident in Ireland) is subject to Irish corporation tax on its chargeable profits, as defined by Section 25 of the Taxes Consolidation Act 1997 (TCA 1997), where it carries on a trade in the State through a branch or agency. "Branch or agency" is the domestic statutory term; in practice, Irish Revenue applies the internationally recognized permanent establishment (PE) framework drawn from the OECD Model Tax Convention and Ireland's network of more than 70 bilateral tax treaties.
Ireland does not define "permanent establishment" exhaustively in statute. Revenue practice follows the OECD Model Tax Convention Article 5 framework, which provides that a PE is "a fixed place of business through which the business of an enterprise is wholly or partly carried on." The OECD definition includes a place of management, a branch, an office, a factory, a workshop, and—for construction or installation projects—a building site that lasts more than a specified duration (typically six or twelve months, depending on the treaty).
Two principal PE triggers for employment-driven situations
When a foreign company hires an employee in Ireland, two PE pathways are most relevant:
1. Fixed-place-of-business PE
A fixed place of business in Ireland through which the foreign company carries on its business wholly or partly constitutes a PE. The test requires:
- Geographical fixity: The business activity is tied to a specific location (an office, a desk in a co-working space, a home office used regularly and exclusively for the employer's business, a factory floor). The place need not be owned or formally leased by the foreign company; disposal of the space is sufficient if the company uses it on a regular and ongoing basis.
- Duration and permanence: The activity must have a degree of permanence. A single sales visit does not create a PE; continuous or regular use of the location over months or years does. Interruptions encountered in the normal course of business (holidays, travel) do not defeat permanence if the business resumes at the same place.
- Business carried on: The enterprise's business—not merely preparatory or auxiliary activities—must be carried on through the fixed place. Revenue distinguishes between core income-producing activities (sales, manufacturing, service delivery, technical support, business development) and purely preparatory or auxiliary functions (storage of goods for display only, collection of information, advertising). Activities that are preparatory or auxiliary in nature are generally excluded from the PE definition under OECD Article 5(4).
Practical implication for remote employees: A foreign company that hires an Irish-resident employee to perform core business functions (sales to Irish or European customers, software development for the company's products, customer success management, finance or HR operations for the global entity) and that employee works from a home office in Ireland on a regular, ongoing basis, may create a fixed-place PE in Ireland. The employee's home office can constitute a "place at the disposal" of the employer if the employer exercises control or direction over where and how the work is performed and the work is performed there regularly (not just occasionally while traveling). Revenue has historically taken a pragmatic view, focusing on the nature and degree of the activity and whether the location is genuinely at the employer's disposal; a few days per year does not create PE, but months or years of continuous remote work by an employee performing revenue-generating or core operational duties does present material PE risk.
2. Dependent-agent PE (agency PE)
Even without a fixed place of business, a PE arises if a dependent agent in Ireland has, and habitually exercises, authority to conclude contracts in the name of the foreign enterprise. This pathway is codified in OECD Model Tax Convention Article 5(5) and is expressly recognized in Ireland's tax treaties and Revenue practice.
The test requires:
- Dependent status: The agent must be economically or legally dependent on the foreign enterprise. An independent agent acting in the ordinary course of its business (a broker, commission agent, or any other agent of independent status) does not create a PE for the principal, provided the agent's business is not devoted exclusively or almost exclusively to that one principal. Employees are almost always dependent agents.
- Authority to conclude contracts: The agent must have legal authority to bind the foreign company contractually. This authority may be formal (a power of attorney, a delegation letter, an express term in the employment contract) or may be established by the agent's conduct and the enterprise's acceptance of that conduct. The agent need not physically sign contracts; it is sufficient if the agent negotiates all material elements of a contract in a manner that binds the enterprise, even if formal signature occurs elsewhere (for example, a sales employee in Ireland who negotiates price, scope, and delivery terms with Irish customers and the foreign head office routinely rubber-stamps the deal).
- Habitual exercise: The authority must be exercised regularly, not occasionally. Revenue applies the same continuity test as for the fixed-place PE: one contract does not create PE; a pattern of contract conclusion over months or years does. The frequency must be normal for the line of business.
Practical implication for sales and business-development employees: A foreign company that hires an Irish-resident employee as a sales manager, account director, or business-development lead—who has authority to negotiate and conclude contracts with Irish or EMEA customers in the company's name—creates a dependent-agent PE in Ireland from the date the employee habitually begins exercising that authority. This is the most common employment-driven PE trigger for foreign companies entering the Irish market. The employee need not be Irish-resident; an intra-company transferee from the foreign head office who is posted to Ireland and exercises contract authority creates the same PE.
Consequences of having a PE in Ireland
If a foreign company is found to have a PE in Ireland—whether by fixed place of business or dependent agent—the company becomes chargeable to Irish corporation tax on the income and chargeable gains attributable to that PE. The consequences include:
- Corporation tax registration: The company must register with Irish Revenue for corporation tax purposes, obtain a tax reference number, and file annual corporation tax returns (Form CT1).
- Profit attribution: The foreign company must compute the "relevant branch income" attributable to the PE using transfer-pricing principles, treating the PE as if it were a separate and independent enterprise dealing at arm's length with the rest of the company. This requires a functional analysis showing the functions performed, assets used, and risks assumed by the Irish PE.
- Corporation tax rate: Profits from trading activities attributable to the Irish PE are taxed at Ireland's 12.5% corporation tax rate (for trading income) or 25% (for non-trading income, passive income, certain excepted trades). If the foreign company's home jurisdiction provides a foreign tax credit for Irish tax paid, or a branch exemption for foreign-branch profits, the net additional tax burden may be minimal or zero. However, the compliance and documentation burden is real.
- Branch registration with the Companies Registration Office (CRO): A foreign company carrying on business in Ireland through a branch (a non-resident company with a place of business in Ireland) must register the branch with the Companies Registration Office under Part 21 of the Companies Act 2014. This is a corporate / commercial-law obligation separate from the Revenue tax registration, but triggered by the same underlying PE facts.
Mitigating PE risk — the entity-vs-EOR decision
Foreign companies hiring their first employee in Ireland typically choose one of three structures to manage PE risk and compliance:
1. Establish an Irish subsidiary (limited company)
Incorporating an Irish private company limited by shares (LTD) gives the foreign parent a separate Irish legal entity. The Irish subsidiary is the employer, holds the PAYE/PRSI registration, files Irish corporation tax returns as an Irish-resident company (taxed on worldwide income, subject to treaty relief), and bears the employment and operational liabilities. This approach eliminates PE risk for the foreign parent (assuming the subsidiary is a genuinely independent entity with substance and economic reality, not a sham or shell) but imposes the full cost of Irish entity formation, annual statutory filings with the CRO, audit (for companies above the small-company thresholds), and corporate governance.
2. Use an Employer of Record (EOR)
An Employer of Record (EOR) is a third-party service provider that acts as the legal employer of the Irish employee on behalf of the foreign company. The EOR holds the Irish PAYE/PRSI employer registration, issues the employment contract and written statements, operates payroll, files real-time PAYE returns to Revenue, and remits PRSI to the Social Insurance Fund. The foreign company remains the economic employer (the employee performs work for the foreign company, receives direction from the foreign company, and may use the foreign company's systems and branding) but is not the legal employer for Irish employment-law and payroll purposes.
The EOR structure does not eliminate PE risk for the foreign company if the employee's activities would otherwise create a PE. If the employee works from a fixed place in Ireland performing core business functions for the foreign company, or if the employee habitually concludes contracts in the foreign company's name, the foreign company still has a PE under Irish tax law; the existence of an EOR as the legal employer is ignored for PE purposes because the EOR is transparent (the business being carried on is the foreign company's business, not the EOR's business). However, the EOR simplifies payroll compliance and employment-law administration, and many foreign companies accept the PE risk (either because the attributed profits would be minimal, or because a foreign tax credit eliminates double taxation, or because the 12.5% Irish rate is favorable) while deferring the cost and complexity of setting up an Irish entity until headcount or revenue justifies it.
3. Register directly with Revenue and operate payroll without an Irish entity
A foreign company with no Irish entity can register directly with Irish Revenue as an employer, obtain an Employer Registration Number, implement compliant payroll software or engage an Irish payroll bureau, submit real-time PAYE returns, and file Irish corporation tax returns for the PE's attributed profits (if a PE exists). This approach is uncommon for first-time hirers because it combines the compliance burden of both payroll and PE tax filings without the liability-shielding or structural clarity of an Irish subsidiary or EOR.
Practical takeaway: assess PE risk before hiring, not after
The entity-vs-EOR-vs-direct-registration decision is a threshold question that precedes the hire. PE exposure is driven by the nature of the employee's work (core vs. auxiliary), the location and permanence of the work (home office in Ireland used regularly vs. occasional travel), and the authority granted to the employee (authority to bind the company contractually vs. no external-facing authority). A foreign company hiring a sales director, engineering manager, or country head in Ireland who will work from Ireland and exercise meaningful business authority should presume PE risk and structure accordingly: either establish an Irish entity and accept Irish tax residency for that entity, or use an EOR and prepare for PE reporting. A foreign company hiring a purely back-office support employee (payroll clerk, internal IT support) with no customer-facing or contract-authority role, working remotely from Ireland, presents lower PE risk but is not automatically exempt; the fixed-place-of-business test still applies if the work is regular and the location is at the employer's disposal for a meaningful duration.
Delayed PE assessment—waiting until after the first pay run or the first year of operations—exposes the foreign company to back-taxes, interest, penalties for late registration, and the cost of retrospective profit attribution. The prudent path is to assess PE risk at the offer stage, structure the hire through the appropriate vehicle (entity, EOR, or direct with PE filing), and document the analysis in writing.
