Calculate how much more tax you will have to pay if you’re caught by IR35
Use this calculator to work out your additional tax burden if your contract is inside IR35.
IR35 is intended to tackle tax avoidance by ‘disguised employees’, but the legislation is highly complex and contractors risk being incorrectly classified as caught by IR35. You can learn more in our IR35 guides.
Based on your current rate, this calculator will compare tax liabilities for falling inside and outside of IR35. It also calculates the tax burden for being caught by IR35 as both a cash sum and a percentage increase.
