We believe a robust IR35 compliance process should be detailed yet easy to manage, closely follow IR35 status case law, and crucially, be frictionless to implement.
Our unique blend of exceptional technology, protected by a team of proven experts, will safeguard your business now and in the future.
IR35 is UK tax legislation designed to identify contractors who operate as disguised employees. If your private sector business is medium/large and engages contractors, you are responsible for assessing their IR35 status. Incorrect assessments could lead to unpaid taxes, penalties, and time-consuming HMRC checks. Our services can reduce your risk by helping you assess IR35 status accurately for every contract and working arrangement.
We provide everything your business needs to stay compliant with IR35.
Get consistent, case law-backed IR35 status determinations using our automated assessment software. Designed for medium and large businesses, our tools provide fast, accurate results with clear reasoning to support compliance decisions.
The written contract plays a critical role in determining IR35 status. Poorly worded contracts can weaken your position if HMRC challenges a determination. We review your contracts for IR35 risk and help ensure they support a strong, compliant position.
Our audit process checks your contracts, status decisions, and working practices to identify gaps before HMRC does. Use it to strengthen your compliance process and prepare for potential investigations or internal reviews.
If HMRC opens an enquiry, our experts will manage your defence for you. From reviewing evidence to preparing documentation, we work with your team to protect your business from penalties and disruption.
Equip your staff with the knowledge to manage IR35 responsibilities confidently. Our training covers legal obligations, real-world scenarios, and how to spot issues before they escalate.
Add an extra layer of confidence with IR35 protection. Our Tax Investigation Service covers up to £200,000 of legal costs so you're not left exposed if your business is investigated.

Chat with an expert about our Tax Investigation ServiceThe team successfully defended IT Contractor Richard Alcock at First-tier Tribunal, which defeated two barristers representing HMRC Solicitor’s Office. Chris and Dave worked together for 18 months to build the case defence before defending during a four day hearing. They succeeded in countering HMRC’s IR35 Opinion and extended time assessments with the Judge upholding RALC’s appeals.
When a long-time client of IR35 Shield received notice of an IR35 investigation by HMRC, the company turned to IR35 Shield's compliance experts for representation. Within months, the investigation was closed with no tax bill.
Dave and Chris are currently managing a range of IR35 enquiries and also offer consulting for businesses to help ensure their procedures and processes achieve defendable positions in light of the new off-payroll working legislation.
