Frequently asked questions

How is a C/C++ Developer contractor taxed in Ireland?

Your tax treatment depends on your operating structure. PAYE umbrella: the umbrella deducts employer PRSI before calculating your gross, then applies Income Tax, USC, and PRSI (Class A). Sole trader: you pay Income Tax, USC, and Class S PRSI on net profits, which is generally more tax-efficient. Director: treated similarly to sole trader but with director-level PRSI (Class S). The calculator above shows all three side by side.

What is a typical take-home retention rate for C/C++ Developer contractors in Ireland?

Retention rates vary by structure and day rate. Sole traders typically retain 55–65% of gross contract income at mid-market rates after Income Tax, USC, and PRSI. PAYE umbrella structures retain slightly less due to employer PRSI. Higher rates push retention lower as more income falls into the 40% tax band.

Should a C/C++ Developer contractor in Ireland use a sole trader or PAYE umbrella structure?

Sole trader generally gives better take-home at most day rates but requires filing a Form 11 self-assessment return annually. PAYE umbrella is simpler but results in lower net pay because employer PRSI is deducted before your gross is calculated. For most C/C++ Developer contractors, the additional admin of sole trader pays off financially beyond roughly €300/day.
