Every UK adult gets a £20,000 ISA allowance each tax year — completely tax-free. Track how much of your 2026/27 allowance you've used across each ISA type, and see exactly what's left before the 5 April deadline.
For educational purposes only. ISA rules and allowances can change. The allowance resets on 6 April each year. Unused allowance cannot be carried forward.
You have the full £20,000 ISA allowance available this tax year. Any money you put in grows completely tax-free — no capital gains tax, no income tax on interest or dividends.
Knowing your allowance is step one. Understanding which ISA type suits your goals, how to invest inside a Stocks & Shares ISA, and how to claim your LISA bonus is where the real advantage is. Our free courses cover all of it.
