The basic tax rate is 20% on earnings above your PAYE annual threshold for personal allowance (as above) and up to £34,500 for the tax year 2018-2019. These amounts it is also spread throughout the year. You will pay 20% on earnings above personal allowance thresholds (point 2) and up to:
- £664 per week
- £2,875 per month
- £34,500 per year if paid only once in a year.
If your earnings on a period (weekly, monthly or yearly) are higher than these thresholds, any earnings above these thresholds will be tax at the higher rate of 40%. There is a further tax rate of 45% but only for earrings above 150,000 but I will not go into further detail about this additional UK tax rate, you could find more information here.
