Adaptive

There was a lot of pressure throughout the compliance check, like one wrong step and it could all go wrong. However, IR35 Shield briefed us on how things may develop, which enabled the business to prepare for potential events. It felt as if HMRC were fault-finding, not fact-finding, so being forewarned really helped us.

How we defend your business from an HMRC IR35 compliance check

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.

They succeeded in countering HMRC’s IR35 Opinion and extended time assessments with the Judge upholding RALC’s appeals.
