UK ISA Withdrawal Calculator 2026 — Tax-Free Savings & Reinvestment Strategy

You can withdraw any amount from your ISA at any time without penalty. However, if you withdraw and then re-invest, it may use your annual allowance.

Withdrawals themselves do not reduce your annual allowance. You can withdraw and redeposit the same amount in the same tax year without losing allowance room.

The annual ISA allowance is £20,000 for the 2026/27 tax year. This combined limit applies across all ISA types: Cash ISAs, Stocks & Shares ISAs, Innovative Finance ISAs, and Lifetime ISAs.

Yes. You can have one Cash ISA and one Stocks & Shares ISA simultaneously. Withdrawals from any ISA don't affect your ability to contribute elsewhere, provided you stay within the £20,000 annual limit.
