From April 2016, a tax-free allowance of £1,000 (or £500 for higher rate taxpayers) will be introduced for the interest that people earn on savings. If they are a basic rate taxpayer and have a total income up to £42,700 a year, they will be eligible for the £1,000 tax-free savings allowance.
If they are a higher rate taxpayer and earn between £42,701 and £150,000, they’ll be eligible for a £500 tax-free savings allowance, but those with income in excess of £150,000 a year will be taxed in full on their interest income.
