If you’re a UK investor looking to make the most of your Individual Savings Account (ISA), you might have come across the term 'Bed & ISA'.
Bed & ISA is a financial strategy that can help you shelter more of your investments from tax liabilities.
Here’s a quick rundown of what it is, how it works, and why it might be worth considering.
What is Bed & ISA?
Bed & ISA is a process where you sell investments such as stocks, funds, or bonds held outside an ISA and immediately repurchase them within an ISA wrapper. 'Bed' refers to selling assets, while 'ISA' is about bedding them down into your tax-efficient ISA account.
It’s a common process for UK investors who have not maxed out their annual ISA allowance (£20,000 as of 2025) but still hold taxable investments elsewhere, such as in general investment accounts (GIAs).
The goal with Bed & ISA is to shift assets into an ISA where future growth, dividends, and interest can be shielded from capital gains tax (CGT) or income tax.
This is particularly salient toward the end of the tax year when some people can find themselves with spare allowance in their overall ISA annual limits.
However, it’s not about avoiding tax on past gains, but protecting yourself against future liabilities.
How does Bed & ISA work?
The process is simple but involves a few steps. First, you sell your investments held outside an ISA through your broker or platform; this might trigger a CGT liability if the asset has grown beyond your annual CGT allowance (currently £3,000).
Next, you use the proceeds to buy the same (or similar) investments back within your ISA, assuming you have enough of your ISA allowance left. Some platforms handle this as a single transaction to minimise market risk, meaning you’re not left exposed if prices shift between selling and buying.
Remember, it's important to ensure the process doesn’t cause any issues for your investments, and timing is essential. You can’t repurchase the exact same shares outside an ISA within 30 days without tripping over HMRC’s "bed and breakfasting" rules, but moving them into an ISA sidesteps this neatly.
What are the benefits of Bed & ISA?
The central reason for performing Bed & ISA is tax efficiency. Inside an ISA, you won’t pay CGT on future profits or income tax on dividends, unlike in a regular trading account.
Over time, this can add up, especially if your investments grow significantly. It’s also a way to consolidate your portfolio, making it easier to manage everything under one tax-free roof.
There are costs to weigh up, including platform fees, potential CGT on the initial sale, and the bid-offer spread of investments. But for long-term investors, the tax savings can often outweigh these.
With the tax year nearing its end, it's important to act quickly if you still have unused ISA allowance or investments outside the tax-free wrapper.
Bed & ISA is a smart, tax-efficient tweak to maximise your ISA’s power. That being said, if you have any concerns over the procedure, how much tax you could save, or how your investments are managed, it's critical to consider consulting with an adviser who could help you through the process.
