The personal allowance for 2018/19 is £11,850. However, some individuals do not benefit from the full personal allowance. There is a reduction in the personal allowance for those with ‘adjusted net income’ over £100,000, which is £1 for every £2 of income above £100,000. So for 2018/19 there is no personal allowance where adjusted net income exceeds £123,700.
The basic rate of tax is currently 20%. From 6 April 2018 the band of income taxable at this rate is £34,500 so that the threshold at which the 40% band applies is £46,350 for those who are entitled to the full personal allowance. Additional rate taxpayers pay tax at 45% on their income in excess of £150,000.
The tax on income (other than savings and dividend income) is different for taxpayers who are resident in Scotland to taxpayers resident elsewhere in the UK. The Scottish income tax rates and bands apply to income such as employment income, self-employed trade profits and property income
