Who we are: 

Contracting compliance issues are complex – from self‑employed status, IR35, S44, CIS, Umbrella compliance and MSC legislation. A single mistake can trigger costly HMRC challenges. At Markel Tax our team brings over 20 years of specialist insight from those legally qualified, former HMRC professionals and those who have run their own recruitment and umbrella businesses -so we understand all the commercial pressures agencies face.

We help agencies strengthen their contracts and processes through full supply‑chain audits, providing clear visibility of any risk and practical recommendation to improve their position which will support you to grow your business with confidence.
