Pay Periods in Ireland: What Employers and Employees Need to Know

Understanding pay periods is crucial for both employers and employees. For Irish businesses, choosing the right pay period can impact cash flow, employee satisfaction, tax obligations, and administrative workload. In this article, Osservi breaks down everything you need to know about pay periods in Ireland—from legal requirements and common practices to strategic payroll planning.

What Is a Pay Period?

A pay period is the recurring schedule by which an employee is paid. It determines how often employees receive their wages and directly affects payroll processing cycles.

Common types of pay periods include:

• Weekly

• Fortnightly (every two weeks)

• Monthly

• Bi-monthly (twice a month)

• Four-weekly

In Ireland, employers can choose the most appropriate pay frequency for their business—provided it complies with employment law and is clearly outlined in the employment contract.

Legal Framework for Pay Periods in Ireland

Under the Payment of Wages Act 1991, employees in Ireland are entitled to:

• Know when they will be paid and how often.

• Receive a payslip for each pay period.

• Get paid on a regular and predictable basis.

Employers must communicate the pay period in the written terms of employment (commonly referred to as the “contract of employment”) given to employees within five days of starting work.

Failing to adhere to this can result in penalties and claims made to the Workplace Relations Commission (WRC).

Types of Pay Periods and Their Pros and Cons

1. Weekly Pay

• Common for: Hourly workers, contractors, construction, hospitality.

• Pros:

  • Employees receive frequent income.

  • Easy to adjust for overtime and variable hours.

• Cons:

  • Higher administrative burden.

  • More complex payroll processing.

2. Fortnightly Pay

• Common for: Retail, logistics, part-time employees.

• Pros:

  • Balances regular income and admin load.

  • Still flexible for workers with changing shifts.

• Cons:

  • Can confuse employees who budget monthly.

  • May require more frequent payroll runs.

3. Monthly Pay

• Common for: Salaried and full-time employees in corporate environments.

• Pros:

  • Reduced administrative workload.

  • Easier monthly cash flow management for employers.

• Cons:

  • Employees must manage longer gaps between paydays.

  • Delays in correcting errors affect the entire month.

4. Four-Weekly Pay

• Common for: Some manufacturing and legacy payroll systems.

• Pros:

  • Predictable structure (every 28 days).

  • 13 pay periods per year (extra cycle helps annual planning).

• Cons:

  • Doesn’t align with calendar months.

  • Confusing for annual budgeting and statutory deductions.

Statutory Considerations in Irish Payroll

Employers must consider how pay periods affect:

• Income tax (PAYE)

• Universal Social Charge (USC)

• PRSI contributions

• Pension deductions

• Holiday accrual and sick pay

For example:

• PAYE tax bands apply differently for weekly vs. monthly pay periods.

• Cumulative tax credits must be divided evenly based on pay frequency.

Osservi’s payroll services ensure accurate tax computation based on your chosen pay schedule, preventing costly errors and compliance issues.

How Pay Periods Impact Payroll Management

For Employers

• Choosing the right pay period helps with cash flow forecasting.

• A longer pay period (monthly) reduces processing frequency but requires accurate forecasting of hours/overtime.

• Shorter pay periods can improve employee morale but increase processing costs.

For Employees

• Pay frequency affects budgeting and financial planning.

• Employees must know how their tax is calculated and how deductions work per period.

Osservi recommends employee self-service payroll portals to help staff access payslips, track deductions, and understand net pay in real time.

How to Choose the Right Pay Period for Your Business

Choosing the right pay frequency depends on:

• Industry norms

• Size of the business

• Type of workforce (salaried vs. hourly)

• Cash flow capacity

• Payroll team resources

Tip: Businesses undergoing rapid growth or workforce changes may benefit from a professional payroll partner like Osservi to evaluate the best structure and ensure seamless implementation.

• Provide written notice to employees.
