From April 2016, HMRC introduced a tax-free Personal Savings Allowance of £1,000 (or £500 for higher rate taxpayers) on the interest that you earn on your savings.
To be eligible, for the £1,000 tax-free Personal Savings Allowance, your taxable income needs to be less than £46,350 a year in 2018/19.
To be eligible for the £500 tax–free Personal Savings Allowance, your taxable income needs to be between £46,351 and £150,000 a year.
Examples, provided by HMRC are as follows:
| Example 1 | 
 If you earn £20,000 income a year and £250 in interest  | 
 From April 2016 you won’t have to pay tax on your interest as it is within your £1,000 Personal Savings Allowance.  | 
|---|---|---|
| Example 2 | 
 If you earn £20,000 income a year and £1,500 in interest  | 
 You won’t need to pay any tax on your interest up to £1,000, but you will still need to pay tax on the £500 interest you have earned over your Personal Savings Allowance. You will pay tax at the 20% savings rate.  | 
| Example 3 | 
 If you earn £60,000 income a year and £250 in interest  | 
 You won’t have to pay tax on your interest as it is within your £500 Personal Savings Allowance.  | 
| Example 4 | 
 If you earn £60,000 income a year and £1,100 in interest  | 
 As a higher rate tax payer you won’t have to pay tax on your interest up to £500, but you will still need to pay tax on the £600 interest you have earned over your Personal Savings Allowance. You will pay tax at the 40% savings rate.  | 
Please note that from April 2016, banks and building societies will stop automatically taking 20% in income tax from interest earned on your non-ISA savings.
