IR35 is tax avoidance legislation targeting ‘deemed employees’ - workers supplying their services to clients via an intermediary (such as a limited company) who would be classed as employees under employment law if not for the intermediary, and so should be taxed like employees.
Falling foul of the Act can lead to substantial costs in back taxes, fines and penalties and liability can now be traced to not only to your limited company, but also your agency or hirer. On top of this, falling within IR35 tax status means you could suffer a 20% decrease in net take-home pay.
These are the main factors affecting employment status, as per case law, and are based around the relationship between the contractor and the end hirer. IR35 Shield divides these into four - substitution, mutuality of obligation, control and other factors - and asks many detailed questions to accurately determine your employment status.
You can take an assessment as many times as you like. If you require the Staus Determination Statements, certificates and tax investigation insurance associated with these assessments, you need to purchase IR35 Shield for Contractors.
Our complex algorithms were built by industry-leading experts who have consulted with the Treasury on IR35. They are regularly refined in line with the latest IR35 tribunal case outcomes and regression tested for robustness against our extensive database of previously conducted assessments. So you get up-to-date employment legislation applied across every evaluation, without bias. Every time.
No. We do not send your data anywhere. If you are invited to take an assessment via an agency, accountant or other IR35 Shield client, your data will belong to the company that invited you. But if you complete your assessment using our IR35 Shield individual plan then the data is held securely in our servers and only you can access.
Tax law dictates that contracts in place as long as 20 years ago can be investigated. This means that IR35 Shield has carefully considered our data retention policies, which can be read about in our Terms and Conditions.
CEST only uses a basic checklist to determine status, rather than IR35 Shield’s highly complex weight-based algorithmic solution. IR35 Shield asks 101 questions, CEST asks 16. IR35 Shield has correctly predicted the status determinations of all previous IR35 tribunals; CEST was incorrect in over 30% of those tribunals. IR35 Shield gives a definitive determination on 98% of cases, CEST categorises 25% of cases as “indeterminate”.
A human expert would typically take 2-3 hours to deliver an assessment, charge hundreds of pounds, and could take days. Our solution will provide an accurate Status Determination Statement in 15 minutes, at any time of the day, for any number of concurrent assessments, and is not subject to human error or bias.
No. Our membership provides tax investigation insurance for assessments completed either before or during the contract but it does not cover contracts completed before the assessment. We advise that you take membership for any new contracts, then take more assessments for your historic contracts and keep a copy of the assessments alongside your contracts. For extra peace of mind, try to get your previous clients to sign off historic assessments using the sign off sheet at the back of the Status Determination Statement.
Built by industry-leading experts, using complicated algorithms and utilising Amazon’s latest auto-scaling, serverless technology, our virtual lawyer can assess thousands of contractors in a single day, evaluate them on a 19 point scale between outside and inside IR35, and generate a comprehensive Status Determination Statement for each individual. Our virtual IR35 lawyer puts the pieces together, stands back and evaluates the whole.
Artificial Intelligence – or AI – is the term applied when a machine mimics the cognitive functions typically attributed to a human in order to carry out a certain task. Already widely adopted in sectors such as medicine and finance, AI continues to permeate our daily lives in a variety of ways and is being credited for reimagining entire industries.

IR35 is tax avoidance legislation targeting ‘deemed employees’ - workers supplying their services to clients via an intermediary (such as a limited company) who would be classed as employees under employment law if not for the intermediary, and so should be taxed like employees.
Changes announced starting in April 2020 to the private sector mean every organisation, both public and private sector, engaging contractors will be affected by IR35.
  • Hirers determine the IR35 status of contractors
  • Agencies are responsible for calculating and deducting tax from contractors’ pay
  • Agencies risk liability for unpaid tax and penalties if an IR35 evaluation is incorrect
  • Accountants risk losing their contractor clients, as contractors are forced into payroll solutions
These are the main factors affecting employment status, as per case law, and are based around the relationship between the contractor and the end hirer. IR35 Shield divides these into four - substitution, mutuality of obligation, control and other factors - and asks many detailed questions to accurately determine your employment status.
Our complex algorithms were built by industry-leading experts who have consulted with the Treasury on IR35.

No! Our virtual IR35 lawyer can handle as many assessments as you can throw at him. We harness a mind-boggling new technology provided by AWS (Amazon Web Services) which allows us to automatically scale up our architecture to handle thousands of simultaneous assessments and Status Determination Statements, whenever the need arises.
Don’t worry - if you run out of credit, you will still be able to invite contractors to take the assessment, and they will still be able to complete it. However, if you wish to unlock the finished assessment (ie. view and download the Status Determination Statement) you will need to top up your credits to do so.
IR35 Shield has a setting to allow you to decide how much your contractor will see after completion of their assessment. This will be decided and implemented on setup, and can be changed at any time.

There are no other systems like IR35 Shield currently available. To avoid a case of “unknown unknowns”, we show you a demo of IR35 Shield and explain each screen and function. After you’ve seen this demo, we will happily provide you with a populated trial version so you can use the system armed with prior knowledge of how best to use it.
Although our development team has extensive experience in employment and taxation law, IR35 Shield is a software product, built by software experts. Offering legal advice, charging hours for consultancy, or working on sales forces us to spend less time on our core business - software development. This is why we created a white-label product for experts in accountancy, employment and law to use, harnessing the power of our software alongside the expertise provided by our Certified Partner. Best of all, this allows us to continue doing what we do best - building great software.
