Definition and overview
An ISA, or Individual Savings Account, is a tax-efficient wrapper for savings and investments in the UK. The ISA allowance 2025/26 represents the total you can contribute to all your ISAs combined in one tax year without incurring tax penalties. For instance, if you put £10,000 in a Cash ISA and £10,000 in a Stocks and Shares ISA, you reach the full tax-free ISA allowance 2025 limit.
Tax year timeline
The 2025/26 tax year starts on 6 April 2025 and ends on 5 April 2026, as confirmed by Yorkshire Building Society.

This timeline ensures the ISA allowance 2025/26 aligns with HMRC’s fiscal calendar.
