when does isa allowance reset

ISA Allowance Reset Date
The ISA (Individual Savings Account) allowance in the UK resets at the start of each new tax year, which begins on 6 April. For the 2026/27 tax year, this means your fresh £20,000 allowance became available from 00:00 on 6 April 2026 —right after the 2025/26 tax year ended at 23:59 on 5 April 2026.

Since today is 11 March 2026, you're still within the 2025/26 tax year (6 April 2025 to 5 April 2026). You have until 11:59pm on 5 April 2026 to max out your current £20,000 allowance, or it vanishes—no carryover allowed.

Key ISA Allowance Facts

• Annual Limit : £20,000 total across all your ISAs (Cash ISA, Stocks & Shares ISA, etc.) for 2025/26 and 2026/27. Note: Cash ISA drops to £12,000 in 2027/28.

• Tax Year Cycle : Always 6 April to 5 April. Deposits processed on/after 6 April count toward the new allowance.

• No Rollovers : Unused allowance doesn't carry forward; use it or lose it.

• Multiple ISAs OK : Split across types (e.g., one Cash ISA, one Stocks & Shares), but only one of each type per year.

Why It Matters Now (March 2026)

With the deadline looming in less than a month, many savers are rushing to top up before 6 April. Recent forum chatter and news highlight panic over forgotten contributions—don't let £20,000 slip away tax-free! Imagine planting £20k now in a high-yield Cash ISA at ~4-5% rates; that's potential £800-£1,000 interest by next year, all sheltered from tax.

Trending Tip : Check your provider's processing times—some need funds by 4 April to count for 2025/26. Tools like HMRC's ISA calculator or provider apps show your used allowance instantly.

"You have up until 11:59pm on April 5th 2026 to make the most of your current ISA allowance — otherwise you’ll lose it forever."

1. Review Usage : Log into your ISA accounts today—most show remaining allowance.
