ISA Deadline 2026: Use Your £20,000 Allowance Before 5 April

Every year, the ISA deadline tends to sneak up on us. We know it’s coming, yet every March, there’s a collective scramble to beat the midnight buzzer on 5 April. For the 2025/26 tax year, your £20,000 allowance is "use it or lose it." If you don’t hit "confirm" by the 5th, that tax-free ceiling resets to zero on the 6th. You can’t roll it over, and you can’t get it back. But this year isn't just another calendar reset. Missing the 5 April cut-off doesn't just mean losing your allowance; you may end up paying more tax on returns outside an ISA.
