FAQ — Self-Employed Tax Calculator
Which taxes do I pay on self-employed profits in Ireland?+
Three layers: income tax at 20%/40% after the Personal and Earned Income Tax Credits, USC including the 3% self-employed surcharge above €100,000, and Class S PRSI at 4% subject to the annual minimum. The calculator totals all three from your net trading profit.
What is the Earned Income Credit?+
A tax credit for self-employed individuals who have no access to the PAYE credit, now aligned in value with it. It is applied automatically here alongside the Personal Credit.
Why is my USC higher than an employee's on the same income?+
Because of the self-employed surcharge: an extra 3% of USC applies to relevant self-employed income above €100,000. Below that level, the USC computation is the same as for an employee.
