What Is Sole Trader?
By PayMetric Labs Research Desk
Short answer
A sole trader is the simplest self-employment structure: you register directly with the tax authority, invoice clients under your own name, and pay tax on net profit through an annual self-assessment return.
As a sole trader, there's no legal separation between you and your business, you and the business are the same entity, which means simpler setup and accounting, but also that you're personally liable for any business debts. You invoice clients or agencies directly, deduct allowable business expenses from your revenue, and pay Income Tax and social insurance on what's left (net profit), not on your gross invoiced amount.
In Ireland, sole traders file an annual Form 11 return with Revenue and pay Income Tax at the standard PAYE bands (20% up to the standard rate cut-off, 40% above), plus Class S PRSI and USC. It's generally considered the simplest of the three main Irish contractor structures (alongside PAYE umbrella and limited company director), though it offers less scope to defer or shelter income than operating through a company.
Sole trader status suits shorter engagements or lower day rates where the accounting overhead and reduced flexibility of a limited company aren't worth it. As income and contract length grow, many contractors switch to a limited company structure for the extra tax planning flexibility.
