IR35 Calculator

Not sure if you are inside or outside of IR35? Our calculator can help.

Do you provide your services through a limited company?

If the answer’s yes, then HMRC need to be convinced that you’re not using your limited company to disguise a relationship with your client which would otherwise be that of employment.

Don’t be alarmed if you’re confused – so are most of HMRC and the MPs overseeing the legislation – that’s why it’s best to make certain your limited company’s position with some professional help.

To help you navigate the IR35 minefield, use our IR35 calculator – based on HMRC’s own Business Entity Tests – to determine your risk of being caught by the legislation.

Have you ever actually provided a substitute?


Do you carry out any of the services from your own office?


Does your company have to work set hours stipulated by your client?


Other than observing client specifications, are you told how to do the work?


Do you need to seek permission from your client to take time off?


Are you obliged to carry out tasks not covered within the scope of your contract?


Does your notice period exceed 30 days?


Does your company carry any business insurances? EL, PL, PI etc…


Is your company financially liable to correct any faulty work?


Were you ever a permanent employee of your end client?


Do you have any line management responsibilities over client staff – appraisals, disciplinary etc?


Do you have an ‘office holder’ position within the client’s organisation (director, chairman) with high level managerial responsibilities, such as control over budgets etc?
