What United Kingdom Investors Need to Know in 2026
British investors should prioritise a Stocks & Shares ISA before any general investment account. All gains inside an ISA are completely exempt from Capital Gains Tax and dividend tax — no limits, no time restrictions.
The UK's CGT annual allowance has been cut to £3,000 (from £12,300 in 2022/23). This makes the ISA wrapper more valuable than ever.
Post-Brexit, the UK operates independently from EU MiFID II. UK FCA regulation is considered equivalent in quality. US ETFs (SPY, QQQ) are accessible to UK investors — the PRIIPs restriction does not apply.
