This document summarizes upcoming changes to income tax personal allowances for individuals aged 65-74 and aged 75 and over in the UK. Beginning in the 2013-14 tax year, the higher personal allowances will be restricted based on an individual's date of birth. The amounts of the allowances will no longer be increased annually. The changes are aimed to simplify the tax system and spread relief fairly across age groups. They are estimated to raise £360 million for the UK exchequer in 2013-14.
