How do you tax interest? What is the personal savings allowance?
Subscribers: see your detailed guide to this topic Savings income: How interest is taxed
This is a freeview 'At a glance' guide to the taxation of savings income.
Savings income is interest earned, typically on a cash balance, whether paid to you by a bank, building society or any other source.
At a glance
- There is both a tax-free savings band (the starting rate band for savings) and a tax-free personal savings allowance.
- Banks and building societies (since 6 April 2016) generally pay savings income gross (without tax being deducted).
- If you have lent cash to your own company it will pay interest net of a deduction of 20% tax:
- See company guide: Interest paid to directors and individuals
- See director guide: Interest relief: Making a loan to a close company
- Savings income from qualifying ISAs is tax-free.
The Starting Rate Band (SRB)
When savings income falls in the £5,000 SRB, it is taxable at the savings rate (0%).
The scale of the SRB is subject to levels of other income (excluding dividend income): it is not always £5,000. The more non-savings income an individual has (e.g. wages/pension), the less the SRB will be.
- Every £1 of other income above the personal allowance (£12,570) reduces the SRB by £1.
- The savings band is not available if other income exceeds the sum of the personal allowance and the savings band (£17,570)
The Personal Savings Allowance (PSA)
The PSA applies even if you do not qualify for the SRB.
From 2016-17, the PSA effectively exempts savings income within the allowance for basic and higher rate taxpayers. The allowance is £1,000, reduced to £500 for higher rate taxpayers and £0 for additional rate taxpayers, meaning that:
- Basic rate taxpayers do not have to pay tax on the first £1,000 of their savings income.
- Higher rate taxpayers do not have to pay tax on the first £500 of their savings income.
- Additional rate taxpayers are fully taxable on their savings income.
