Hello everyone! On this site we talk frequently about the benefits of investing and ideally making use of an ISA for the tax-saving benefits (don’t worry if you missed ISA’s, you can read more about them here! ) Today I’m going to be looking at the Bed and ISA, which is a simple technique for maximising those ISA benefits.
(If you’re unclear what an ISA is, we suggest starting with our post on why use an ISA.
The Bed and ISA strategy involves selling investments held outside of an ISA and then using the proceeds to buy them back within the ISA. This effectively “beds” the investments into the tax-efficient wrapper of an ISA, allowing you to avoid capital gains tax and potentially reduce income tax.
By taking advantage of the tax wrapper in this way, you can make the most of your investment returns and minimise your tax liabilities. It’s a smart move for anyone looking to build long-term wealth while keeping their tax bill as low as possible.
As ever – our normal note that we take care with what we write on this site but it is not official “financial advice” and whatever investments and savings you enter need to be right for your circumstances. We always suggest doing your own further research. If you’re in doubt about anything, it’s worth consulting a regulated and reputable financial advisor who can provide tailored advice built for you.
Unbiased is a resource that can help you match with an advisor who matches your needs.
What is a Bed and ISA?
As with many things in the financial markets, what sounds a complex term is actually something extremely simple.
It simply refers to selling investments held in a general account (where increases in value and dividends will be subject to additional tax if you go beyond annual allowances) and rebuying those investments in an ISA to made use of your annual allowance.
How can I transact a Bed and ISA?
It depends on your provider as to how many steps you have to go through. in all cases it’s something pretty simple to do, but some make it a click of a button (literally having a Bed and ISA option) and some require you to go through a few steps.
What we’ll do is talk through the whole process of what happens to aid understanding and let you know what you need to do.
Just remember that you’re able to pay a maximum of £20,000 in each tax year into any type of ISA, and can’t exceed this.
- You’ll need to sell your existing investments in your general account and convert this into cash. (For avoidance of doubt as it’s a logical question, you do have to sell and rebuy, you cannot simply move the investments from one account to other).
- Transfer the money from your general account into your ISA.
- Purchase your new investments in the ISA.
- Done!

Are there any potential downsides with a Bed and ISA?
Briefly out of the market
You’ll be very briefly “out of the market” when selling the investments in your general account, meaning that you might be advantaged or disadvantaged by any price movements during this period (i.e, you may be able to buy your investments back cheaper than you sold them, but they also may have got slightly more expensive).
Unless you’re in a period of extreme market turbulence we suggest trying not to worry about this too much – rebuying for Bed and ISA is fairly quick so any adverse movement is likely to be limited and outweighed by the longer term tax benefit.
Potential costs of dealing
Depending on what you’re buying and selling and the terms and conditions of your provider, you may be charged dealing fees on the purchase and sale.
These are entirely dependent on your provider so we can’t advise you here and you’ll need to check yourself – with some it is free, with some it is not.
If you are trading single name UK shares, you may also have to pay stamp duty.
Tax on a gain may be incurred when you sell
To be clear, this is tax you’re going to have to pay at some point anyhow if you’ve made a gain rather than an additional charge, but if you crystallise (I.E actually make from your sale in reality) more than the £3,000 capital gains tax allowance, you’ll need to pay capital tax in line with your rate of income tax.
Does the 30 day rule apply to Bed and ISA?
For some other sell and rebuy approaches (like “Bed and Breakfasting” which I’ll cover in a separate post) you have to wait 30 days after sale before rebuying the same asset.
For avoidance of doubt, this rule does not apply to Bed and ISA – you can do the sell and rebuy immediately.
Are there alternatives I should think of beyond putting my money into an ISA?
If you don’t need the money for a long time, a pension is the other extremely beneficial investment savings approach worth considering.
If you’re looking for more here, we’ve got an article right here comparing the benefits of pensions and ISA’s!
We’ve also compared the performance of stocks and shares accounts and savings accounts to help you decide if a stocks and shares or cash ISA may be better for you.
