How the £5,000 starter rate band works
The starter rate for savings is a 0% tax band of up to £5,000, but it sits inside your normal tax bands rather than being granted separately. To benefit, your non-savings income (everything except interest, dividends, and capital gains) must be lower than the sum of your Personal Allowance and the starter band — i.e. £12,570 + £5,000 = £17,570.
Tapering rule: the available starter band equals the larger of zero and (£17,570 − non-savings income). Specifically:
- Non-savings income £0 to £12,570 → full £5,000 starter band available.
- Non-savings income £15,000 → £2,570 starter band available.
- Non-savings income £17,570 or more → £0 starter band.
The starter band is used before the Personal Savings Allowance. So a retiree with £14,000 of pension income and £2,000 of savings interest pays no tax: £2,000 falls into the £3,570 (£17,570−£14,000) starter band at 0%.
Why most workers can't use it (and who can)
For full-time employees earning the National Living Wage (£12.21/hr × 35 hrs × 52 weeks = £22,222 in 2025/26), the starter band is fully tapered away. The starter rate is therefore not a useful planning tool for most working-age people.
Categories who typically benefit:
- Retirees on State Pension only (£11,973 full new amount in 2025/26 → £5,597 starter band, capped at £5,000).
- Pensioners with State Pension plus a modest private pension up to £15k–£17k.
- Students and parents on extended unpaid leave with no current employment income.
- Self-employed in a low-earnings year (e.g. start-up loss-making years).
- Asset-rich, income-poor retirees who took inheritance lump sums and live off savings.
- Couples where one partner has reduced earnings — they should hold most savings in the lower-income partner's name.
Three worked examples (UK 2025/26)
Example 1: Full-state-pension retiree using full £5,000 band
Margaret receives full new State Pension of £11,973 (2025/26). She has £100,000 in fixed-rate bonds at 4.5% paying £4,500 of interest. Non-savings income £11,973 — below £17,570.
Calculation: Personal Allowance covers £11,973 of pension, leaving £597 of PA spare. Starter band: £17,570 − £11,973 = £5,597, capped at £5,000. PSA: £1,000. Total tax-free: £597 + £5,000 + £1,000 = £6,597 against £4,500 interest. Tax due £0. Margaret could earn £2,097 more in interest before paying anything.
Example 2: Pensioner with workplace pension — partial band
Henry receives State Pension £11,973 + workplace pension £4,500 = £16,473 of non-savings income. He earns £3,000 of interest from a £75k deposit.
Calculation: PA covers £12,570 of pension; remaining £3,903 of pension taxed at 20% = £780.60 (already deducted via PAYE on the workplace pension). Starter band: £17,570 − £16,473 = £1,097. PSA: £1,000. So £1,097 + £1,000 = £2,097 tax-free; £903 of interest taxable at 20% = £180.60.
Example 3: Student couple — £0 starter band
Aisha and Tariq are both PhD students with stipends of £19,500 each (taxable as employment for the supervisory portion in some cases — assume taxable). Each has £20,000 in savings at 4% = £800 interest. Non-savings income £19,500 — above £17,570 so starter band is £0 each. PSA each = £1,000.
Calculation: Each: £800 interest within £1,000 PSA = £0 tax. Even without the starter band, the PSA suffices.
Common mistakes to avoid
- Forgetting that the PSA shrinks to £500 once your total income (including the interest itself) crosses £50,270 — high-rate banding.
- Assuming peer-to-peer lending interest counts inside an ISA — only IF ISAs (Innovative Finance) qualify; ordinary P2P platforms do not.
- Treating ISA interest as part of your PSA — ISA interest is fully exempt and never uses your £1,000/£500 allowance.
- Believing children's savings interest is exempt — under the £100 parental settlement rule, interest above £100/parent is taxed on the parent.
- Forgetting partner's savings — couples can split balances to use both PSAs (£1,000 + £1,000 = £2,000 tax-free at basic rate).
- Missing the starter rate for savings — £5,000 at 0% if non-savings income is below £17,570, often overlooked by retirees.
When to use this calculator
Use this calculator if you are a retiree, semi-retiree, sabbatical-taker, or anyone with non-salaried periods producing low employment income but significant cash holdings. Run it once per year when bond rates fix or roll over, and any time your pension income changes (e.g. when a small annuity starts paying, or when a partner's death removes one income source). Couples should examine asset placement: the lower-earner partner can shield far more interest tax-free if they sit below £17,570.
Regional differences (Scotland, Wales, Northern Ireland)
Income tax bands differ in Scotland (Starter 19%, Basic 20%, Intermediate 21%, Higher 42%, Advanced 45%, Top 48%). However, savings interest, dividends, and capital gains are taxed at UK-wide rates regardless of where you live, because these are reserved (non-devolved) tax categories. Wales uses UK rates for income tax (the Welsh rate is currently 10p matched to UK basic rate). Northern Ireland uses UK rates throughout. Your Personal Savings Allowance, Dividend Allowance, and Annual Exempt Amount are identical across all UK nations.
