Understanding ISA Withdrawals in the UK

ISA Allowance Rules

The UK ISA allowance is £20,000 per tax year (April-March). This is a combined limit across all ISA types. Withdrawals do not reduce the allowance for future redeposits in the same tax year.

Tax-Free Status

ISA interest and investment returns are tax-free even after you withdraw. Withdrawals are never taxed, making ISAs advantageous for savings.

Multiple ISAs Strategy

You can hold a Cash ISA and a Stocks & Shares ISA at the same time. Withdrawals from either don't prevent future contributions, provided you stay within the annual limit.

Redeposit Flexibility

Withdrawn funds can be redeposited in the same tax year. This flexibility allows you to move money between accounts or product types while managing allowance efficiently.

Frequently Asked Questions

Clear answers to common questions to help you use this calculator confidently.

How much can I withdraw from my ISA?

Tap to view the answer

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.

Does withdrawing from my ISA affect my annual ISA allowance?

Tap to view the answer

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.

What is the UK ISA allowance for 2026/27?

Tap to view the answer

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.

Can I have multiple ISAs and withdraw from each one?

Tap to view the answer

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.
