The 20% basic rate band is £31,785 for 2015/16 and will be £31,900 for 2016/17. This means that you pay 40% tax if your taxable income exceeds £42,385 for 2015/16 and £42,700 for 2016/17. It is proposed that the higher rate tax threshold will increase to £43,300 for 2017/18. The 45% top rate continues to apply to taxable income over £150,000 for 2015/16.
