The Irish Fractional CSO Landscape
Demand for part-time commercial leadership concentrates in Dublin SaaS and fintech, Galway medtech and Cork life sciences, with pipeline and ARR accountability the recurring brief. The ERF Q1 2026 Labour Market Monitor recorded temporary and contracting roles overtaking permanent recruitment in 2025, at 48% of net fee income against 44% for permanent placement. Sourced base salaries for a full-time CSO run 180,000 to 250,000 euros (Morgan McKinley 2026 Ireland Executive Salary Guide, Robert Half Ireland 2026). Day rates for a fractional CSO run 900 euros at entry, about 1,250 euros senior and up to 1,800 euros at the top (Fractional Edge rate card 2026, PayMetric Labs 2026).
Karshan Framework, DPC Direct Marketing, Sales Compensation under Irish Law
Ireland does not apply IR35: employment status follows the Supreme Court ruling in Revenue Commissioners v Karshan (Midlands) Ltd of October 2023, which set a five-step sequential test covering the work and wage bargain, substitution, control, a holistic review of the terms and the legislative context, with Revenue publishing its Guidelines for Determining Employment Status for Taxation Purposes (Part 05-01-30) in May 2024. Fractional CSOs therefore contract through a personal limited company, as a sole trader, or via a PAYE umbrella (PayMetric Labs 2026). Where a contractor is reclassified, the engaging company becomes liable for unremitted PAYE, USC and PRSI: BDO Ireland illustrated a 21,017 euro re-grossed liability on 20,000 euros of net pay (BDO Ireland, September 2025). Employer PRSI on a salaried CSO is comparatively low at about 11.25% for Class A (Saffery, NKC and PwC 2025-26), so the employer-charge saving is smaller in Ireland than in most European markets, and the case for fractional rests on time bought rather than on charge arbitrage.
