Frequently Asked Questions

Find answers to common questions about ISA wrappers, allowances, and choosing between Cash ISA and Stocks and Shares ISA.

What is the annual ISA allowance for 2026?

UK residents aged 18+ can subscribe up to £20,000 per tax year across all ISA wrappers combined. This allowance resets on 6 April each year.

Can I hold both a Cash ISA and a Stocks and Shares ISA simultaneously?

Yes, you can hold one of each type in the same tax year, but your combined subscriptions cannot exceed £20,000. Funds in one wrapper are completely separate from the other.

Are Cash ISAs flexible? Can I withdraw money without penalty?

Flexible Cash ISAs allow withdrawals without tax consequences, though some may revert withdrawn amounts on reinvestment. Traditional Cash ISAs offer fixed terms. Always check your provider's specific terms.

Is growth in a Stocks and Shares ISA tax-free?

Yes. Capital gains, dividend income, and interest within a Stocks and Shares ISA are all tax-free, even if they exceed the normal capital gains tax or dividend allowance.

What happens to my ISA if I move abroad?

You remain liable for UK tax on ISA income and gains only while classified as a UK resident. Check HMRC guidance and inform your ISA provider of any residency changes.

Can I switch between Cash ISA and Stocks and Shares ISA mid-year?

You can transfer existing balances between providers or wrapper types. Transfers preserve your ISA status and do not count against your annual allowance.
