Bed & ISA Transfer
The Formal Definition
A UK-specific administrative procedure wherein an investor sells holdings inside a taxable General Investment Account (GIA) and immediately repurchases the identical securities inside a tax-free Stocks & Shares ISA to shelter future gains from Capital Gains Tax.
Sheltered Capital = Realized GIA Holdings Sold (Utilizing Annual CGT Allowance) → Cash Repurchased Inside Annual £20,000 ISA Limit
Cole Barrett's Reality Check
The Unvarnished Bottom Line"A Bed & ISA transfer is the UK investor's legal escape hatch from HMRC. You cannot transfer physical shares directly from an ordinary account into an ISA by law, so your broker sells the shares, moves the cash into the ISA, and re-buys the stock. The trap? Bid-ask spread toll and stamp duty eat into your principal if your broker handles it clumsily."

How Brokers Weaponize This Term
Legacy UK investment platforms market Bed & ISA transfers as 'free platform services' while charging dealing commissions on both the sale leg and the repurchase leg, alongside 0.5% UK Stamp Duty on repurchased equities.

Does selling shares for a Bed & ISA trigger UK Capital Gains Tax?
Yes. The sale leg inside your General Investment Account is a taxable disposal and counts toward your annual Capital Gains Tax allowance.
Do you have to pay UK Stamp Duty on a Bed & ISA repurchase?
Yes. Repurchasing UK common stock inside the ISA wrapper incurs the standard 0.5% Stamp Duty Reserve Tax (SDRT).
