What are the PRSI classes?

Class A is the most common for private sector employees. Your class determines the rate of social insurance you pay and the benefits you receive.

What is the Universal Social Charge (USC)?

USC is a tax on your gross income, introduced to replace other levies. It has its own set of progressive rates.

Tax credits directly reduce the amount of Income Tax (PAYE) you pay. Everyone is entitled to personal and employee tax credits.

Ireland has weight-based income tax tiers, along with Universal Social Charge (USC) and social insurance (PRSI).

PAYE Rates: 20% on income up to the cutoff, 40% on balance.
Tax Credits: Reduce the amount of PAYE you owe (e.g., Personal Tax Credit, Employee Tax Credit).
USC: A tax that applies to your total gross income with its own progressive brackets.
PRSI: Mandatory social insurance (typically 4% for Class A employees).
