By Chandraketu Tripathi · Updated April 2026 · Fact-checked ISA · April 2026One of the most significant changes to ISA rules in recent years took effect in April 2024: you can now pay into multiple ISAs of the same type in the same tax year. Previously, you could only contribute to one Cash ISA per year. Now, you can split your £20,000 annual allowance across as many cash ISAs as you like — from as many providers as you like. Here is everything you need to know.
The New Multiple ISA Rules — April 2024 ChangeBefore April 2024, HMRC rules only permitted contributions to one ISA of each type per tax year. For cash ISAs, this meant choosing a single provider. If the best easy access rate was with Provider A and the best fixed rate was with Provider B, you could only use one of them in that tax year. Since April 2024, this restriction has been removed. You can now contribute to as many Cash ISAs as you like in a single tax year, as long as your total contributions across all ISAs do not exceed £20,000. This allows you to split between an easy access ISA for flexibility and a fixed rate ISA for a higher guaranteed return — both in the same tax year. 💡 The multiple ISA rule change is particularly valuable for savers who want to split between an easy access ISA (emergency fund) and a fixed rate ISA (locked savings earning a higher rate). You can now hold both simultaneously without waiting for the next tax year. Practical Examples of Multiple ISAsExample 1: You contribute £5,000 to a Chip easy access Cash ISA (4.84% AER) as your emergency fund, and £15,000 to a SmartSave 1-year fixed Cash ISA (4.70% AER) for savings you do not need to access. Total ISA contributions: £20,000 — within the annual allowance. Example 2: You contribute £10,000 to a Trading 212 Cash ISA and £10,000 to a Stocks and Shares ISA with InvestEngine. Total: £20,000 — perfectly within the rules. Note that you can combine different ISA types as well as multiple providers of the same type. ISA Transfer RulesTransferring existing ISA money between providers does not count as a new subscription — it is free and does not affect your annual allowance. Always use an official ISA transfer form from your new provider rather than withdrawing and redepositing, which would use up your annual allowance. ⭐ OUR VERDICT The multiple ISA rule change since April 2024 significantly improves the flexibility of ISA saving. Take advantage by splitting your £20,000 annual allowance between an easy access ISA (for liquidity) and a fixed rate ISA (for a better return) — both tax-free, in the same tax year. Always check the specific terms of each ISA before contributing to ensure it allows top-ups within the same tax year, as some fixed rate ISAs only accept a single deposit at opening. Frequently Asked QuestionsCan I pay into two cash ISAs in the same tax year? Yes — since April 2024, you can contribute to multiple Cash ISAs with different providers in the same tax year. Your total contributions across all ISAs (cash, stocks and shares, innovative finance, Lifetime) cannot exceed £20,000 in 2026/27. Can I have a cash ISA and a stocks and shares ISA at the same time? Yes. You can contribute to both a Cash ISA and a Stocks and Shares ISA in the same tax year, as long as your total contributions across both do not exceed £20,000. This has always been permitted. Do I need to tell HMRC about all my ISAs? No — ISA providers report to HMRC on your behalf. You do not need to declare ISA interest or gains on your tax return. HMRC uses information from providers to monitor compliance with the annual allowance. What happens if I accidentally pay into two cash ISAs above the £20,000 limit? If you exceed the £20,000 annual ISA allowance, HMRC will contact you to inform you. The excess will need to be removed from the ISA. HMRC takes ISA breaches seriously — if you have multiple ISAs with different providers, keep careful track of your total contributions. |
