How Much Savings Interest Can You Earn Tax-Free?

Frequently Asked Questions

What is the Personal Savings Allowance (PSA)?

The PSA lets you earn savings interest tax-free. Basic rate taxpayers get £1,000 PSA; higher rate taxpayers get £500; additional rate taxpayers get £0.

What is the starting rate for savings?

The starting rate band is up to £5,000 of savings income taxed at 0%. However, it is reduced pound-for-pound if your non-savings income (salary, pension) exceeds the personal allowance.

Who benefits from the starting rate for savings?

People with low earned income (below about £17,570). If your salary plus pension is below £17,570, you can earn up to £5,000 of savings interest at 0%, in addition to your PSA.

Do ISA savings count towards the PSA?

No. Interest in Cash ISAs and Stocks & Shares ISAs is completely exempt from income tax and does not count towards your PSA limit.

How much savings interest can I earn tax-free in 2025/26?

It depends on your income. A basic rate taxpayer could earn up to £1,000 (PSA) completely tax-free. Someone with very low non-savings income could earn up to £6,000 (£1,000 PSA + £5,000 starting rate).

Do I need to declare savings interest on self-assessment?

If your savings interest exceeds your PSA, you should report it. HMRC may automatically collect tax through a PAYE code adjustment if the amount is below £10,000. Self-employed people should always include it.

What counts as savings income?

Bank/building society interest, NS&I savings income (some products), most interest from peer-to-peer lending, interest from investment bonds (some), and some types of dividend/interest from investment trusts.

Does the PSA apply to offshore savings?

Yes, the PSA applies to all savings interest received by UK residents, including interest from overseas accounts. All interest must be declared on self-assessment if it exceeds the PSA.

What tax rate applies to savings above the PSA?

Basic rate taxpayers pay 20%; higher rate taxpayers pay 40%; additional rate taxpayers pay 45% on savings interest above their PSA.

Are Premium Bond prizes taxable?

No. Premium Bond prizes (winnings) from NS&I are entirely tax-free and do not count towards the PSA.

How does the PSA interact with higher rate threshold changes?

If you're pushed into the higher rate band by fiscal drag, your PSA drops from £1,000 to £500. This is an additional cost of the frozen higher rate threshold.

Can couples combine their PSAs?

PSAs are per individual, not joint. A couple each earn their own PSA. Holding savings jointly means each earns 50% of the interest, using 50% of their respective PSAs.
