In the Budget today George Osborne announced that the personal allowance would be increased to £11,000 a year with effect from the 2017/18 tax year. This will be preceded by another increase in the personal allowance to £10,800 for the tax year 2016/17.
There have been a number of increases in the personal allowance over the last few years and these increases come after the recent increase in the personal allowance for the year 2015/16 to £10,600.
