Capital Gains Tax Raid! How the 'Bed and ISA' Strategy Saves Your Stock Profits in 2026

⚠️ Senior Editor's Note (Jan 2026): The Capital Gains Tax (CGT) annual exempt amount remains at a rock-bottom £3,000 for the 2025/26 tax year. This means 'Bed and ISA' is no longer just for the wealthy—it is essential for anyone with a modest portfolio. Be aware: selling shares to move them counts as a "taxable event."

Capital Gains Tax Raid!

For years, UK investors enjoyed a generous tax-free cushion. You could realize over £12,000 in profit on stocks and pay absolutely zero tax.

Those days are effectively over. The fiscal landscape has shifted dramatically.

In 2026, your tax-free allowance is a measly £3,000. If your profit outside of an ISA exceeds this by even £1, you must report it to HMRC and pay Capital Gains Tax (up to 20% for higher rate taxpayers).

However, there is a legitimate strategy used by astute investors to shield their wealth permanently. It involves migrating your assets from a "Taxable General Investment Account (GIA)" to a "Tax-Free ISA." This is known as Bed and ISA.

What is 'Bed and ISA'?

You cannot simply transfer shares directly into an ISA (known as an in specie transfer). HMRC rules dictate that you can only subscribe cash into an ISA.

Therefore, the 'Bed and ISA' process is a manual workaround:

1. Sell: You sell your shares in your General Investment Account (GIA). Note: This crystallizes your gain or loss.
2. Transfer: You move the cash proceeds into your Stocks & Shares ISA.
3. Buy: You immediately repurchase the same shares (or different ones) inside the ISA wrapper.

Once inside the ISA, those assets are ring-fenced. They can grow to £1 million, and you will never pay Capital Gains Tax or Dividend Tax on them again.

The "Bed and Breakfasting" Rule (Why This Works)

HMRC enforces a strict anti-avoidance rule called "Bed and Breakfasting."

It states: "If you sell a share and buy it back within 30 days in the SAME account, the sale is ignored for tax purposes." This prevents investors from artificially manipulating their tax bill.

Crucially, this rule does NOT apply to ISAs.

Because an ISA is a completely separate tax entity, you can sell in a GIA and buy in an ISA instantly without violating the 30-day rule. It is 100% compliant and efficient.

The Cost: Is It Worth It?

While the tax savings are massive, the process is not free. You must account for:

• Trading Fees: Commissions to sell and buy (e.g., £5-£10 per trade).
• The Spread: The difference between the market buy and sell price.
• Stamp Duty (UK Stocks): When buying back UK shares, you typically pay **0.5% tax**. (US stocks and ETFs are generally exempt).

Compare these transactional costs (perhaps £50 total) against a potential future tax bill of thousands. The math heavily favors the strategy.

The Limit: £20,000 Per Year

You are limited by your annual ISA allowance. You can only contribute up to £20,000 per tax year (resetting on April 6th). If you hold £50,000 in a taxable account, you must execute this strategy over multiple tax years.

Account Type	Capital Gains Tax	Dividend Tax
General Account (GIA)	Yes (Above £3k profit)	Yes (Above £500)
Stocks & Shares ISA	Never	Never

Chief Editor’s Verdict

The deadline is April 5th, 2026. If you do not utilize your £20,000 ISA allowance by then, it is lost forever.

Your Action Plan
1. Audit your General Investment Account for unrealized gains.
2. Calculate if selling will trigger a tax bill today (does the profit exceed £3,000?).
3. Execute the 'Bed and ISA' to fill your £20,000 allowance.
4. Secure your future growth from HMRC's reach.
