Understanding IR35
The Intermediaries Legislation β widely known as IR35 β is a body of tax law embedded within the Finance Act. Its purpose is to prevent individuals from gaining tax advantages by operating as contractors when the reality of their working relationship closely mirrors that of a traditional employee. If you invoice through a limited company or personal service company yet your working arrangements resemble permanent employment, IR35 may apply to you.
What Do the Latest Changes Mean for You?
Under the reformed rules, contractors working through their own limited company who are engaged by medium or large private sector businesses are now assessed on their IR35 status by the end client β not the contractor themselves. If you are deemed to fall inside IR35, the agency or end client becomes responsible for deducting income tax and National Insurance before you receive payment.
This means you may no longer be able to pay yourself through dividends or offset certain business expenses. Instead, you would be taxed as an employee of your own company, subject to Corporation Tax, Employer's National Insurance, and PAYE deductions on top of that.
Does IR35 Apply to Everyone?
Not necessarily. If you operate as a genuinely independent contractor β running a real business, serving multiple clients, using your own equipment, and setting your own working patterns β the rules may not apply to your situation. The key is being able to demonstrate that independence clearly and consistently.
HMRC provides an online determination tool (CEST), though it has been widely criticised for producing ambiguous results. We strongly recommend speaking with one of our compliance advisors before relying on any single tool for your status assessment.
The SDC Test Explained
Supervision, Direction and Control (SDC) is one of the primary tests used to determine whether a contractor falls inside or outside IR35. It examines four key dimensions of how work is performed:
π Supervision
Is there someone overseeing the quality and completion of your work? Supervision can exist even when it's occasional or provided for training purposes.
π§ Direction
Are you instructed on how to carry out the work β following specified processes, methods, or procedures set by someone else?
π Control
Does someone else determine your hours, location, task priorities, or workflow? If your working day is largely dictated by a client, control may apply.

If your contract is determined to fall inside IR35, there is no need to worry. Twenty Four Seven MS provides a fully compliant umbrella employment arrangement.

When Does the Legislation Apply?
The off-payroll working rules currently apply to all medium and large private sector companies, as well as all public sector bodies. If your end client falls into one of these categories and determines your role to be inside IR35, you must ensure you are receiving your pay through a compliant channel β such as our umbrella service β before commencing or renewing that contract.
