What is Bed & ISA and should I use it?

Bed & ISA lets you sell investments in a taxable account and immediately buy them back inside your Stocks & Shares ISA (using your £20,000 allowance). It shelters future growth and income from tax permanently, with no 30-day waiting rule.

Why it matters more than ever

Since 2023, the annual CGT allowance has been cut from £12,300 to £3,000. CGT rates rose in October 2024 to 18% (basic rate) and 24% (higher rate). Every pound of growth sitting in a general account outside an ISA is future CGT liability accumulating in real time.

How it works in practice

  1. Identify investments in your general account with gains within or close to your £3,000 CGT allowance
  2. Sell them — this crystallises the gain, but within the allowance there is no tax charge
  3. Immediately repurchase the same investments inside your ISA
  4. All future growth is permanently sheltered from CGT

The 30-day rule does not apply when repurchasing inside an ISA — you can sell and rebuy the same day.

Key takeaway: Bed & ISA is one of the simplest and most effective ways to move assets into tax-free status each year.
