How are Income Tax, USC, and Class S PRSI calculated for a Sole Trader in Ireland in 2026?

Irish sole traders deduct allowable business expenses (TCA 1997 s. 81) from gross turnover to arrive at net Schedule D profit; neither Class S PRSI nor USC is tax-deductible. In 2026, Income Tax is 20% up to 44,000 € (single) and 40% above, reduced by the 2,000 € Personal Tax Credit and up to 2,000 € Earned Income Credit. USC applies above 13,000 € profit at 0.5% / 2% / 3% / 8% (plus a +3% self-employed surcharge = 11% above 100,000 €), and Class S PRSI applies from 5,000 € profit at a blended 4.2375% rate (4.20% Jan–Sep, 4.35% from Oct 1, 2026; minimum 650 €/yr).

Why does marginal self-employed tax in Ireland jump above 100,000 € (and when do contractors incorporate an Irish Ltd)?

Above 70,044 € of net Schedule D profit, Irish sole traders face a 52.24% marginal rate (40% IT + 8% USC + 4.2375% PRSI), and above 100,000 € an extra +3% self-employed USC surcharge pushes the marginal rate to 55.24%.
