Designed for contractors.

For contractors who want to run a limited company but are afraid of being caught out by IR35, Simplex offer a unique and innovative solution. Whilst many contractors have been forced to abandon limited companies and work through an umbrella, at Simplex we’ve gone a different route, ensuring that our limited company contractors remain compliant within IR35 whilst still maximising their take home pay. We offer our contractors the best of both worlds – all the convenience and ease of use of an umbrella company whilst still retaining the financial advantages of a limited company.
