What is a tax-free personal allowance? Your personal allowance is the amount you can earn each year before you pay tax. It is given to you in equal portions throughout the year, so that by the end of the tax year you have received your full allowance. In the 2017/18 tax year, the personal allowance for most people increased from Â£11,000 to Â£11,500.
Income tax is the single largest source of government revenue, making up about 30% of the total, followed by National Insurance contributions at around 20%. Each person has an income tax personal allowance, and income up to this amount in each tax year is free of tax. For the 2015/16 tax year, the tax-free allowance for under-65s with income less than Â£100,000 is Â£10,600.
