How much income tax you pay will depend on your earnings and tax-free allowances.

How much income tax do I pay?

You're able to earn a certain amount of income tax-free each year. In the 2018-19 tax year, that personal allowance is £11,850. 

On income between £11,851 and £46,350, you'll pay income tax at 20% - known as the basic rate.

Between £46,351 and £150,000, you'll pay at 40% (known as the higher rate) and above £150,000, you'll pay 45% (the additional rate). 

Note that you're personal allowance decreases by £1 for every £2 you earn over £100,000. This means that in 2018-19 once your income is over £123,700, you'll be taxed on your full earnings, and between £120,000 and £123,700 you'll effectively be charged 60% tax as you lose the 20p/ £1 personal allowance. The point at which you'll fully lose your personal allowance in 2019-20 will be £125,000.
