If you're an employee in Ireland, you'll see three main deductions on your payslip: Income Tax, Universal Social Charge (USC), and Pay Related Social Insurance (PRSI). Understanding USC and PRSI is key to figuring out your true take-home pay.
What is Universal Social Charge (USC)?
USC is a tax on your total income. It was introduced in 2011 to replace the income levy and health levy. Unlike income tax, there are very few tax credits or reliefs that can be used to reduce it. It's charged in bands, with the rate increasing as your income rises.
What is Pay Related Social Insurance (PRSI)?
PRSI contributions are made by both employees and employers and go towards the Social Insurance Fund. This fund pays for a wide range of social welfare benefits. The amount you pay is a percentage of your earnings, and most employees fall into 'Class A'.
