The Chancellor Philip Hammond has announced in his 2017 Budget today that the personal allowance will increase with effect from April 2018 to £11,850.
This is the amount that people can earn before having to pay any tax on earnings above that level.
An increase of £350 in the personal allowance means an extra £70 a year (or £5.83 a month) in the pocket of a basic rate tax payer.
Currently the personal allowance sits at £11,500 for the year 2017/18 and so this is an increase of 3.04%.
The eventual aim that has been proposed by the government is to get the personal allowance to £12,500 a year.
The higher rate tax bracket will also be increase from £45,000 to £46,350. The aim is for this to be increased eventually to £50,000.

Also announced in the Budget today was the increase in the National Minimum Wage of 4.4%, rising from £7.50 an hour to £7.83 an hour with effect from April 2018.
