Should I operate as a sole trader or limited company in Ireland?

Both structures are common in Ireland and each has distinct advantages. Sole trader: simpler and cheaper to set up and run, profits taxed at Income Tax rates (20%/40%) plus USC and PRSI Class S, minimal annual filing requirements (Form 11), no separate company tax return. Limited company: Corporation Tax at 12.5% on trading income (significantly lower than personal Income Tax rates), limited personal liability, ability to retain profits in the company, and more flexible pension and remuneration planning. The tax crossover point: at higher income levels (typically above €50,000–€80,000 profit), incorporating as a limited company can save significant tax because 12.5% Corporation Tax is much lower than 40%+ Income Tax. However: a company involves annual accounts, a Corporation Tax return (CT1), a Company Directors Annual Return, and potentially payroll — so costs and admin increase. Always get personalised advice from an accountant before deciding.

  • Sole trader: simple, profits taxed at 20%/40% IT + USC + PRSI
  • Limited company: 12.5% Corporation Tax on profits — big saving vs 40% IT
  • Crossover point: typically above €50,000–€80,000 profit, company may be more tax-efficient
  • Company: more admin (CT1, annual returns, payroll) and accountancy costs
  • Irish 12.5% Corporation Tax is one of Europe's lowest — a significant advantage at scale
