What is Payroll tax compliance?

Payroll tax compliance involves more than just paying taxes. Employers must calculate the right amounts for income tax, PRSI (Pay Related Social Insurance), and USC (Universal Social Charge). Employers also need to report payroll information regularly to Revenue and keep detailed records of all payments. This process ensures employees’ taxes are up to date and that employers meet all legal requirements.

Payroll taxes impact both employee earnings and employer obligations. Failure to comply can result in penalties, interest charges, and damage to reputation. Therefore, understanding payroll tax compliance is the first step toward managing payroll correctly.

Main payroll taxes and statutory deductions

In Ireland, there are three main payroll taxes every employer must handle carefully. These are:

• PAYE (Pay As You Earn): This is the income tax deducted from an employee’s paycheck. Employers are responsible for calculating and deducting the right amount based on the employee’s tax credits and tax rates.
• PRSI (Pay Related Social Insurance): This is a social welfare contribution paid by both employers and employees. PRSI helps fund social welfare benefits like illness, unemployment, and pensions.
• USC (Universal Social Charge): USC is a tax charged on gross income before any tax credits. Unlike PAYE or PRSI, only employees pay USC, but employers must deduct it accurately.

Here is a simple overview of who pays each tax:

Payroll Tax Type	Employer Pays	Employee Pays	Purpose
PAYE (Income Tax)	No	Yes	Taxes income
PRSI	Yes	Yes	Social insurance support
USC	No	Yes	Additional charge on income

In 2025, payroll tax rates and bands remain in effect with some changes following the Budget announcements. Employers must stay updated on these rates to deduct the correct amounts from each employee’s pay.

Employer payroll obligations and reporting deadlines

Besides deducting payroll income taxes, employers have important reporting and record-keeping duties. Irish payroll law requires that employers submit payroll data to Revenue in real-time before or on the employees’ payday. This system is called Real Time Reporting (RTS) under PAYE Modernisation.

Employers must ensure all employee pay, tax credits, and deductions details are correct in these regular submissions. Failure to report on time can lead to penalties. Payroll reporting deadlines depend on the employer’s payroll frequency but must be consistent and timely.

Employers must provide detailed payslips to each employee. Payslips should clearly show gross pay, each statutory deduction (like PAYE, PRSI, USC), net pay, and employer contributions. Keeping detailed payroll records is mandatory; business owners should keep records for at least six years.

Irish payroll legislation changes in 2025

The Irish government has introduced new payroll rules in 2025, including the introduction of automatic enrolment payroll for workplace pensions. This means employers must automatically enroll eligible employees in a pension scheme and contribute alongside the employee.

Another key update is the increase in the National Minimum Wage to €13.50 per hour for employees aged 20 and over, effective from January 1, 2025. Employers must update their payroll systems to ensure all payments meet this new legal minimum.

Employers should update their payroll policies and software to reflect these changes and ensure full compliance. Regularly reviewing payroll legislation ensures that any budget-related tax rate changes or reporting rules are implemented on time.

Data security and digital record-keeping

Under GDPR, employers must protect all employee payroll data, including tax details, bank information and pay records.

Key best practices include:

• Storing payroll data securely on encrypted, access-controlled systems.
• Maintaining digital backups in Revenue‑approved formats.
• Keeping records only as long as required (six years minimum).
• Ensuring employee data access is limited to authorised personnel.

Digital record‑keeping also simplifies payroll audits and compliance checks.
