What is the ISA allowance for 2025/26?

The total ISA allowance is £20,000 per tax year for adults. This is split across all your ISAs — you can put the whole £20,000 in one type or divide it. The Lifetime ISA has a separate £4,000 limit within the £20,000. Junior ISA limit is £9,000.

Can I have multiple ISAs UK?

Yes — from 2024/25 onwards, you can pay into multiple ISAs of the same type in one tax year. Previously you could only pay into one Cash ISA per year. Now you can split £20,000 across multiple Cash ISAs, multiple Stocks & Shares ISAs, etc.

What is the Lifetime ISA limit?

£4,000 per year, which counts towards your overall £20,000 ISA allowance. So if you put £4,000 in a LISA, you have £16,000 left for other ISAs. Government adds 25% bonus (up to £1,000/year) on LISA contributions.

When does the ISA year end?

The ISA tax year runs 6 April to 5 April. Unused allowance doesn't carry over — use it or lose it. The 2025/26 ISA year ends on 5 April 2026. Many people contribute near the deadline, but consistent saving is usually better.
