The main tax allowances for 2014/15 have increased to the following amounts:
Individual Personal Tax Allowance: £10,000
Individual Personal Tax Allowance for those who were born between 6 April 1938 and 5 April 1948: £10,500
Individual Personal Tax Allowance for those who were born before 6 April 1938: £10,660
So the personal tax allowances for all ages are starting to come into line and the idea is to increase the general personal allowance to £10,500 so there may not be any age advantage at some point in the future.
