IR35 defence services. By proven IR35 experts
In recent years dealing with IR35 and off-payroll enquiries has become highly specialised work. Success now depends on a comprehensive knowledge of the relevant statute and evolving case law, together with extensive experience of HMRC enquiry and tax tribunal work. With our success in tax tribunals against accomplished HMRC Counsel, you can be confident you've hired the right team.
Building a foundation
During the enquiry stage, the team work to help establish the facts and grounds of appeal, designed to maximise the chances of obtaining early closure of the enquiry.
A solid foundation is laid at this stage should the matter have to be brought into appeal proceedings.
Defending in tribunal
Leading up to tribunal, the team spend months intensively preparing and dealing with all detailed directions culminating in skeleton arguments.
During tribunal, our experience enables us to identify and convey to the court the substance of the dispute and why an appeal should be allowed.
