IR35 Shield's knowledge in the IR35 space is exceptional. Our firm, Professional Passport, delivers compliance across the recruitment sector and we are strongly recommending both agencies and clients use IR35 Shield as a way to manage their ongoing IR35 compliance process.

Crawford Temple

Chief Executive Officer

IR35 Shield is both efficient and user-friendly, and it demonstrates reasonable care, providing us and our clients with the necessary assurance. Companies with turnover exceeding £100m that are engaging dozens of contractors are naturally risk-averse, so providing this assurance is crucial.

This creative initiative produced by IR35 Shield is exactly why we did not hesitate to provide insurance to enhance its value for contractors. We are now encouraging our clients to utilise this service to enable them to concentrate on making a living but at the same time provide peace of mind. Well done IR35 Shield!

Peter Blackmore

Chief Executive Officer

Having adopted IR35 Shield as our compliance solution, it’s essentially been business as usual for us. We just open the tool, complete assessments as and when we need to and put the compliance observations into practice. The administration involved is minor. It’s almost as if the Off-Payroll reform never happened.

We have worked collaboratively with the creators of IR35 Shield on IR35 tax cases, winning an appeal at the tribunal with their assistance in 2019. Their knowledge and expertise in this area is exemplary and is clearly reflected in the detailed and comprehensive manner in which they conduct status assessments.

IR35 Shield has enabled us to offer an added value service that we otherwise would not have been able to provide to our clients. By underpinning our compliance offering, it has strengthened our reputation, while its own reputation has helped us get our clients on board with minimal fuss.
