IR35 Calculator

Whilst searching the Internet, you may find several types of IR35 calculators which will tell you your recommended take home pay when working inside or outside IR35.

Some will ask you to simply enter your daily/hourly rate along with whether you work inside or outside IR35, whereas others like the HM Revenue and Customs calculator, works out how much you need to pay to the Revenue if your contract falls inside IR35. HMRC’s ‘IR35 Status check tool’ can be found here:

The issue with using an online IR35 calculator is that no two contracts are the same, which makes it near impossible to get an accurate calculation. Also calculating take home pay whether you are inside or outside IR35 is quite complicated and very much dependent on quite a few variables which even include your short, medium and long term business goals and aspirations never mind your daily rate, approximate expenses, attitude to pensions or likely capital purchases.
