How do I register for PAYE as an employer in Ireland?
To register as a PAYE employer in Ireland, you register with Revenue through ROS using Form TR1 (individuals) or TR2 (companies), and then operate PAYE Modernisation by reporting payroll in real time via Revenue Payroll Notifications.
Detailed Explanation
## How Do I Register for PAYE as an Employer in Ireland?
Once you hire your first employee, you become a PAYE employer and must register with Revenue, deduct and remit income tax, USC, and PRSI from your employees' pay, and file regular returns. Failing to register before paying any employee is a Revenue compliance breach.
## Step 1: Register as an Employer with Revenue
For sole traders and partnerships: Register using Form TR1 through Revenue Online Service (ROS). If you are already registered for income tax or VAT, you can add PAYE employer status through ROS by updating your existing registration.
For companies: Register using Form TR2 through ROS. If the company already has a corporation tax registration, add PAYE employer status to the existing record.
Required information: - Business name and address - PPS number (sole traders) or company registration number - Date from which you will be paying employees - Expected number of employees
Revenue typically processes PAYE employer registrations within 3-5 working days. You will receive an employer tax reference number.
## PAYE Modernisation: Real-Time Reporting
Ireland operates a real-time PAYE reporting system (PAYE Modernisation) which has been in effect since 1 January 2019. Under this system:
- You must report payroll to Revenue **on or before** each pay date (not retrospectively)
- Reports are submitted via **Revenue Payroll Notifications (RPNs)** which employers download before each payroll run
- Employees' tax credits and USC cut-offs are embedded in the RPN, so you do not need to manually enter allowances
You need either Revenue-approved payroll software or an approved payroll bureau to operate PAYE Modernisation correctly.
## PRSI Classes
Payroll taxes in Ireland include employer PRSI (a cost to the employer) and employee PRSI (deducted from the employee's pay). The class depends on the employee's type of work:
| PRSI Class | Employee Type | Employer PRSI Rate | |------------|---------------|-------------------| | A1 | Most employees (private sector, full-time) | 15% | | A1 | Weekly earnings above €500 (lower threshold) | 15% | | S | Self-employed, company directors (sole trader-style) | 0% (paid personally) | | J | Low-paid employees under €38/week, employees over 66 | 0.5% employer | | D | Civil service pensioners | N/A |
For most standard employees, Class A1 applies: employer PRSI of 15% and employee PRSI of 4% on earnings above €352 per week.
The 15% employer PRSI is a significant cost on top of salary. Paying a gross salary of €50,000 costs the employer €57,500 when employer PRSI is included.
## Filing the Monthly P30 Return
As a PAYE employer, you must file a P30 return every month (or quarterly for very small payrolls) through ROS, reporting:
- Total income tax deducted from employees
- Total USC deducted
- Total employee PRSI deducted
- Total employer PRSI due
Payment of all these amounts is due by the 23rd of the month following the payroll period for online filers.
For example, January's payroll taxes are due by 23 February.
## PAYE for Company Directors
Company directors who are proprietary directors (owning more than 15% of shares) are treated differently from standard employees:
- PRSI Class S applies (not Class A): no employer PRSI (0%), but the director pays PRSI at 4% as if self-employed
- Income may also be subject to self-assessment preliminary tax obligations
- If the director is also a controlling director, Revenue may scrutinise the split between salary and dividends
## Annual P35 End-of-Year Return
The P35 is the annual end-of-year PAYE return, due by 15 February of the following year for online filers. It reconciles the monthly P30 returns with the total tax deducted from all employees across the year.

Real-World Examples
Startup hiring its first employee
A SaaS company hires a developer on €60,000 gross. The company must register as a PAYE employer before the first pay date, download the employee's RPN from ROS, deduct income tax, USC, and employee PRSI, and also pay employer PRSI of 15% (€9,000 per year). Total employment cost: €69,000.
Sole trader moving from subcontractor to employee model
A trades business has been using self-employed subcontractors. Revenue audits and reclassifies three workers as employees based on the employment indicators. Retrospective PAYE, employer PRSI, and interest are due from the date of reclassification. PRSI alone could be 15% of three years of wages.
Company director on proprietary director PRSI
The founder of a company owns 40% of shares, making them a proprietary director under PRSI rules. PRSI Class S applies: they pay 4% PRSI personally but the company pays no employer PRSI on the salary. This saves 15% employer PRSI compared to a standard employee at the same salary level.
Common Mistakes to Avoid
- Paying employees before completing Revenue PAYE employer registration, which is a compliance breach that can attract penalties
- Not checking whether a worker should be classified as an employee (PAYE, Class A PRSI) or a self-employed contractor (Class S), since misclassification leads to significant retrospective PAYE and PRSI liabilities
- Missing the monthly P30 payment deadline of the 23rd of the following month, which attracts interest and surcharges on late payment
- Forgetting to factor in employer PRSI of 15% when budgeting for a new hire: a €50,000 salary costs €57,500 in total payroll cost before any other employee benefits
Frequently Asked Questions
How do I register as a PAYE employer with Revenue in Ireland?
Register through Revenue Online Service (ROS) using Form TR1 if you are a sole trader or Form TR2 if you are a company. You will need your PPS number or company registration number and the date from which you intend to pay employees. Processing takes 3-5 working days.
What is PAYE Modernisation in Ireland?
PAYE Modernisation is Ireland's real-time payroll reporting system, in operation since 1 January 2019. Employers must report each employee's pay and tax deductions to Revenue on or before every pay date by downloading Revenue Payroll Notifications and submitting payroll submissions through approved software.
What is the employer PRSI rate in Ireland?
The standard employer PRSI rate is 15% for employees earning above €500 per week (Class A1). For lower-paid employees earning under €38 per week (Class J), the rate is 0.5%. Proprietary directors (owning more than 15% of shares) are on Class S: no employer PRSI applies, but the director pays 4% PRSI personally.
When must the monthly P30 PAYE return be filed?
The P30 must be filed and the associated taxes paid by the 23rd of the month following the payroll period for online filers. January payroll taxes are due by 23 February, February by 23 March, and so on.
Does a sole trader need to operate PAYE on their own income?
No. A sole trader's own income is not processed through PAYE. It is taxed under self-assessment, with income tax, USC, and PRSI Class S declared and paid via the annual Form 11 return. PAYE only applies when the sole trader pays wages to employees or directors.
Practical Tips
- Register as a PAYE employer before offering employment to anyone: Revenue enforcement teams can identify unregistered employers through PRSI records and the penalties for late registration include retrospective liability
- Budget for employer PRSI of 15% on top of every salary: a €45,000 salary costs €51,750 in total, so build this into your hiring budget from the start
- Use Revenue-approved payroll software from day one: manual PAYE calculation is error-prone and PAYE Modernisation requires software integration to submit real-time payroll reports to Revenue
- Check each new worker's employment status carefully using Revenue's Employment Status indicators before classifying them as employee or contractor: misclassification is one of the most common triggers for employer PAYE audits
