What Is USC?
By PayMetric Labs Research Desk
Short answer
USC (Universal Social Charge) is an Irish tax charged on gross income in bands of 0.5%, 2%, 3%, and 8% for 2026, applied on top of Income Tax and PRSI.
USC applies to almost all income, unlike Income Tax, there's no equivalent of the standard rate cut-off band structure softening it at lower income, and it's charged on gross pay before pension contributions are deducted in most cases. The 2026 bands are: 0.5% on the first €12,012, 2% on the next slice, 3% up to €70,044, and 8% on everything above €70,044.
That €70,044 threshold is worth remembering specifically: it's where your USC rate jumps from 3% to 8%, a bigger single-step increase than most people expect, and it means a bonus or pay rise that pushes you just over that line has more of a tax bite than the same amount lower down.
USC is one of three deductions (alongside Income Tax and PRSI) that make up an Irish employee's total tax burden, and it applies to contractors and the self-employed too, calculated slightly differently depending on your structure (sole trader, PAYE umbrella, or director).
