Scope: England, Wales & Northern Ireland. Savings tax rules are UK-wide. Rates shown are indicative as at January 2026.
TL;DR
- Cash ISAs remain 100% tax-free, which matters more after age 60.
- FSCS protection increased to £120,000 per person per bank from 1 December 2025.
- From April 2027, under-65s lose £8,000 of their Cash ISA allowance.
- Over-65s keep the full £20,000 allowance thanks to a campaign led by Martin Lewis.
- Using the ISA wrapper can be worth £200+ per year on the same savings balance.
Why This Matters More After 60
Once you stop working, your income usually falls — but your savings often peak. That flips the tax problem on its head.
Interest that once went unnoticed can now:
- Push you over your Personal Savings Allowance (PSA)
- Create unexpected tax bills
- Reduce the real return on “safe” cash
A Cash ISA solves this cleanly — and in 2026, the rules make timing critical.
FSCS Protection Update (Critical 2026 Change)
As of 1 December 2025, protection under the Financial Services Compensation Scheme (FSCS) increased:
- £120,000 per person, per institution
- £240,000 for joint accounts
This applies equally to Cash ISAs and standard savings accounts held with authorised UK providers.
Advisor insight:
For couples in retirement, this allows six-figure sums to be held in cash without spreading money across multiple banks purely for safety.
Why 2026 Is the Year of the “Last Big Cash ISA” (Under-65s)
This is the single biggest forward-looking change most savers have missed.
The April 2027 Cliff Edge
From April 2027:
- Cash ISA allowance for under-65s falls from £20,000 → £12,000
- That is an £8,000 permanent annual loss of tax-free shelter
The Over-65s Win
After pressure from Martin Lewis, the government confirmed:
- People aged 65+ keep the full £20,000 allowance
What This Means in Practice
- 2026 is the last full year to lock large balances into Cash ISAs if you are under 65
- Once money is inside an ISA, it remains protected forever
This is not a rate decision — it’s a structural tax decision.
Best Over 60s Cash ISA Rates (January 2026)
These are not “special senior products” — they are simply the best-value mainstream ISAs, suitable for retirees who prioritise access and FSCS safety.
Easy Access
- Trading 212 — 4.40%
- Leeds Building Society — 3.96%
1-Year Fixed
- Cynergy Bank — 4.16%
Advisor note:
Fixed ISAs suit savers with no planned withdrawals in the next 12 months. Easy access suits drawdown and emergency buffers.
Example Calculation (Why the ISA Wrapper Matters)
Scenario: £50,000 savings, basic-rate taxpayer, 4% interest.
Standard Savings Account
- Interest earned: £2,000
- Personal Savings Allowance: £1,000
- Tax due: 20% on £1,000 = £200
- Net interest: £1,800
Cash ISA
- Interest earned: £2,000
- Tax paid: £0
- Net interest: £2,000
Verdict:
The ISA wrapper is worth £200 per year, with no extra risk and the same interest rate.
The Transfer Rule Most Over-60s Get Wrong
Never withdraw ISA cash to move it.
If you do:
- You permanently lose its tax-free status
- You may not be able to put it back due to allowance limits
Always use the official ISA Transfer Service.
Your new provider handles everything — the money never leaves the ISA system.
This mistake alone costs retirees thousands in avoidable tax.
The Spouse Advantage (Inheritance Planning Insight)
Cash ISAs do not disappear when someone dies.
Through Additional Permitted Subscription (APS):
- The surviving spouse receives a one-off extra ISA allowance
- Equal to the value of the deceased’s ISA holdings
- On top of their own annual allowance
This allows couples to:
- Preserve tax-free savings
- Simplify estate planning
- Avoid forced taxable reinvestment
For over-60s, APS is one of the most valuable — and least understood — ISA benefits.
Is This Financially Worth It?
- £20k–£80k in savings: ISA almost always beats taxable accounts
- Joint savers: FSCS + APS create powerful combined protection
- Drawdown retirees: Easy-access ISAs prevent tax drag
Main risk: staying loyal to old accounts and letting inflation and tax erode returns silently.

Best ISA for Over 60s in 2025
Most over 60s will benefit most from a high-rate, easy-access Cash ISA (Zopa or Coventry BS), as these provide the best combination of flexibility and returns. If you won’t need to access the funds anytime soon then a fixed-rate ISA (Metro Bank or Close Brothers) pays out better interest.
