How Savings Interest Tax Works

All interest from banks, savings accounts, fixed bonds, credit unions and PayPal balances counts as taxable income unless held inside an ISA.

  • You receive a Personal Savings Allowance based on your tax band.
  • You may also benefit from the £5,000 starting rate for savings.
  • Interest is added to your total income to determine your tax band.
  • Banks report your interest to HMRC automatically.
  • Tax is usually collected via your tax code or Self Assessment.
