UK savers are receiving important reminders about adhering to a crucial financial regulation: the annual £20,000 limit on Individual Savings Accounts (ISAs). This rule applies to the current 2025/26 tax year, which runs from 6 April 2025 to 5 April 2026.
Understanding the ISA Allowance
The Government's official GOV.UK website clearly states: "In the 2025 to 2026 tax year, the maximum you can save in ISAs is £20,000." This allowance can be utilized in a single account or distributed across multiple ISA products, providing flexibility for different saving strategies.
Types of ISAs Covered
The £20,000 annual limit encompasses several ISA varieties:
- Cash ISAs
- Stocks and Shares ISAs
- Lifetime ISAs
- Innovative Finance ISAs
Significant Rule Change
A major development in ISA regulations has transformed saving opportunities. According to Money Saving Expert (MSE), the traditional "one-ISA-per-year" restriction has been eliminated. Since April 2024, savers can open multiple Cash ISAs or multiple Stocks and Shares ISAs with different financial institutions within the same tax year.
MSE clarifies: "Yes. You've always been able to from past years' ISAs, but since April 2024 you've been able to open more than one in the current year too (for example, a fix and an easy access) just as long as you're not putting in more than £20,000 in total."
Current Market Options
For those considering where to place their ISA funds, several competitive options are available:
- Trading212 offers a variable easy access Cash ISA with a boosted rate of 4.43% for the first year, reducing to 3.6% thereafter (rates are variable and subject to change)
- Close Brothers provides a fixed-rate Cash ISA at 4.08% for one year
Important Tax Year Considerations
The MSE website emphasizes critical timing aspects: "Once that year's closed, you can't put another penny in that specific ISA allowance. So if you put aside nothing in the 2023/24 tax year, when the maximum was £20,000, that's it – it's gone."
Similarly, if you deposited only £2,000 during 2023/24, you cannot add additional funds to that specific tax year's allowance now that the period has concluded. However, funds already deposited remain protected within the tax-free wrapper indefinitely.
As each new tax year begins on 6 April, savers gain access to a fresh £20,000 allowance, creating ongoing opportunities for tax-efficient saving and investment growth.
