Stocks and Shares ISA Guide UK 2026
Everything you need to know about Stocks and Shares ISAs. Tax-free investing, allowances, and best providers.
What is a Stocks and Shares ISA?
A tax-free wrapper for investments. Any profits (capital gains) and income (dividends) inside an ISA are completely tax-free. You can invest up to £20,000 per tax year across all ISA types.
ISA vs General Account
Outside an ISA, you pay Capital Gains Tax on profits above £3,000 and Income Tax on dividends above £500. Inside an ISA: £0 tax on everything. Over 10-20 years, this saves thousands.
