When US companies expand into Ireland, the headline salary is only part of the employer cost picture. The bigger differences usually sit in payroll taxes, pension expectations, paid time off, and how exits are handled. Once you understand those categories, forecasting becomes much easier.
This guide breaks down the most common employer cost differences between the US and Ireland, with practical notes for budgeting your first Ireland hire.
The employer cost categories that matter most
For most employers, costs fall into six predictable buckets:
employer payroll taxes and statutory deductions
healthcare expectations and any private cover you choose to offer
pension and retirement saving contributions
paid time off and statutory leave planning
termination-related cost drivers such as notice and redundancy
internal admin time, especially where you do not have an Ireland payroll and HR setup
The employer cost categories that matter most
United States
US employers typically budget for FICA contributions, made up of:
Social Security tax: 6.2% employer contribution
Medicare tax: 1.45% employer contribution
These rates are confirmed by the IRS.
Social Security applies up to an annual wage base which changes each year. For 2026, the Social Security taxable maximum is $184,500.
Ireland
In Ireland, the main employer social insurance cost is employer PRSI (most commonly Class A for employees). Citizens Information sets out the rates and thresholds. As of 1 January 2026, employers pay:
9% on weekly earnings up to €552, and
11.25% where weekly earnings are above €552.
From 1 October 2026, the rates increase again to 9.15% and 11.4% on the same threshold.
In the US, payroll tax cost has a cap element through the Social Security wage base. In Ireland, employer PRSI is more of a steady ongoing cost that scales with earnings.
Healthcare: employer expectations are very different
United States
Healthcare is often one of the largest employer costs in the US because employer-sponsored insurance is a common part of the compensation package. KFF’s Employer Health Benefits Survey reported average annual premiums in 2025 of:
$8,951 for single coverage
$26,993 for family coverage
Employer and employee cost-sharing varies by plan, geography, and workforce demographics, but the premium level explains why healthcare is a major budget line for US employers.
Ireland
Ireland has a public healthcare system, and employers are not required to provide private medical insurance as a statutory benefit. Many employers still choose to offer private cover as a market benefit, particularly for mid-senior roles, but it tends to be treated as an optional perk rather than a default requirement.
US employers often feel healthcare as a fixed expectation for talent attraction. In Ireland, you have more flexibility, and the benefits decision tends to be role and market driven.
Pensions: US 401(k) culture vs Ireland’s auto-enrolment shift
United States
Employers are not generally required to offer a pension. Many offer 401(k) plans with employer contributions as a talent and retention tool, but the approach varies widely by company and sector.
Ireland
Ireland’s retirement savings landscape is changing. Ireland’s auto-enrolment scheme, MyFutureFund, applies to eligible employees and includes employee contributions matched by the employer, with an additional State top-up. Citizens Information summarises how the matching works.
If you are hiring in Ireland, pension planning is moving closer to being a default expectation, particularly for employers scaling a workforce.
Exit costs: notice and redundancy can change your model
Even when you are only hiring one person, exit planning affects employer cost forecasting.
In Ireland, statutory minimum notice periods depend on length of service and range from 1 week (13 weeks to 2 years) up to 8 weeks (15+ years), unless the contract provides longer.
Where redundancy applies and eligibility criteria are met, statutory redundancy is generally calculated as two weeks’ pay per year of service plus one bonus week, using a €600 weekly pay cap for the calculation.
US employers often treat exits as faster operationally, with cost shaped by severance strategy. Ireland exits are more strongly influenced by notice, process, and redundancy rules.
