The 2025/2026 tax year ends on midnight 5 April 2026, and your annual £20k allowance will reset.
You have until midnight on 5 April to use any remaining ISA allowance.
However, this year, the end of the tax year falls on the Easter long weekend.
So in order to guarantee any deposits will land in your ISAs within this tax year, we encourage you to deposit before the deadlines below:
11pm Tuesday 31 March 2026 - Stocks & Shares ISA
11pm Thursday 2 April 2026 - Cash ISA
