The ISA allowance1 is the maximum amount of new money you can put into the range of tax-free savings and investment accounts that make up the ISA family.
The ISA allowance for the current tax year to 5 April is £20,000.
The tax year runs from 6 April to 5 April the following year.
ISAs are a brilliant vehicle for growing your wealth tax-free. But the rules are complicated, and seemingly made up by a bureaucrat with a grudge against humanity.
The purpose of this article is to help you make the most of your ISA allowance. We’ll iron out the wrinkles that aren’t readily apparent on the government’s ISA pages.
What is an ISA?
ISA stands for Individual Savings Account. It’s the UK’s top tax-free account for savings and investments that you want to access before retirement age.
ISAs are called tax-free wrappers because they legally protect the assets inside the account from:
Income tax on interest paid by cash, bonds and bond funds.
Dividend income tax on dividends paid by shares and equity funds.
Capital gains tax paid on the growth in value of assets such as shares, bonds, and funds.
You don’t even have to declare your ISA assets on your self assessment tax return. This can save you a bellyful of tax paperwork.
Your assets remain tax free as long they’re held in an ISA account – and you don’t have the cheek to die.
You don’t even lose out if you move abroad. (At least, not from the perspective of the UK government…)
Unlike a pension, your ISA funds are typically accessible2 at any time.
You’re also not charged income tax on withdrawals from an ISA unlike a pension. So there’s no danger of being pushed into a higher tax bracket by the wealth you accumulate.
But read more about ISAs Vs SIPPs to decide how to best allocate between them.
ISA accounts: what types are there?
Stocks and shares ISA
OEICs, Unit Trusts, Investment Trusts, ETFs, individual shares and bonds
Age 18+. Can be flexible but only the cash component
Savings in instant access, fixed rate, and regular varieties
Age 16+. Can be flexible
Lifetime ISA (LISA)
As per cash ISA or stocks and shares ISA
Open account from age 18-40. Pay in until age 50. Only use for buying first home, or from age 60, otherwise penalty charge
New Help to Buy ISAs are no longer available. If you have one already you can continue to save into it until 30 November 2029.
What about the NISA? NISA stands for New Individual Savings Account. The term was used to describe the new-style ISAs brought in by the Coalition Government of 2014. George Osborne’s NISA rules swept away some awkward restrictions of the past. And replaced them with a raft of new complications! Today every ISA uses the NISA rules. The NISA term is therefore redundant.
How much can I put in an ISA in 2020?
You can save up to £20,000 of new money into your ISAs during the tax year 6 April 2022 to 5 April 2023.
You can put all £20,000 of your ISA allowance into one ISA5 or split it across any combination of the following ISA types:
Stocks and shares ISA
Lifetime ISA (£4,000 annual limit)
Innovative Finance ISA
The rule is that you can only pay new money into one of each ISA type per tax year.
For example you could put £20,000 into a stocks and shares ISA and nothing into any other type.
Or you might split your £20,000 like this:
Stocks and shares ISA = £14,000
Lifetime ISA = £4,000
Innovative Finance ISA = £1,000
Cash ISA = £1,000
Or any other combination you like. Just so long as you don’t pay in more than £20,000 within the tax year, and you don’t put new money into more than one of each ISA type.
What about money in previous years’ ISAs? That money does not count towards your annual ISA allowance for the current tax year.
For clarity’s sake, we’ll refer to assets in your previous years’ ISAs as old money. Assets in the current tax year’s ISAs we’ll term new money.
Interest, dividends, and capital gains do not count towards your ISA allowance, either.
Your £20,000 ISA annual allowance is a ‘use it or lose it’ deal. You can’t rollover any of it into the following tax year.
The ISA deadline for using up your allowance this tax year is 5 April 2023.
More ISA wrinkles
Each ISA can be held with the same or a different provider.
Payment into a JISA uses up the child’s allowance, not yours.
Some providers have all-in-one cash ISAs. With these you can split new money between instant access and fixed-rate options, within a single ISA wrapper. That means you only count as contributing to a single cash ISA.
The Help to Buy ISA counts as a cash ISA. If you pay new money into your Help to Buy ISA then you can’t also pay new money into a Cash ISA. A few providers include their Help to Buy ISA within their all-in-one cash ISA.
A workplace ISA counts as a stocks and shares ISA. If you’re one of the three Britons6 who own one then you can’t pay new money into a standard stocks and shares ISA, too. See below for our cunning workaround.
You can only claim the government bonus when buying your first home from a Help to Buy ISA or a Lifetime ISA. Not both.
Withdrawing from an ISA: the flexible option
If you withdraw money from your ISA, can you replace it and not reduce your ISA limit?
Yes, but only if your ISA is designated as ‘flexible’.
If your ISA is not flexible (ask your provider) then a withdrawal reduces your tax-free ISA savings.
You put £10,000 into your ISA. That reduces your ISA allowance to £10,000.
You withdraw £5,000.
You can still only contribute another £10,000 into your ISAs this tax year.
The maximum you’ll have put into your ISAs this tax year is £15,000.
Flexible ISAs get around this problem – see below. Again, ask your provider if your ISA is flexible or check its key features documentation.
How many ISAs can I have?
You can have as many ISAs as you like. Or as many as providers are willing to open for you.
However you just can’t contribute new money to multiple ISAs of the same type in the same tax year.
That rule remains the same whether we’re talking about a freshly opened ISA or one that you hold from previous years.
You can put new money into a previous year’s ISA if your ISA provider allows.
If you put new money into a previous year’s ISA (for example a stocks and shares ISA) then you can’t put new money into another stocks and shares ISA.
The government calls this the one-type-of-ISA-a-tax-year rule. (Snappy!)
However you can open new ISA accounts by transferring old money into them from previous years’ ISAs.
You could open ten stocks and shares ISAs with multiple providers by transferring old ISA money into them. Let sanity be your guide.
That leads to an obvious workaround for moving new money into more than one ISA of the same type. More on this below.
An ISA transfer enables you to officially switch an ISA’s holdings to another provider. This way you avoid losing the tax exemption on your assets in doing the move.
The transfer rules for any ISA opened in the current tax year are straightforward:
You must transfer the whole balance of your ISA…
…and you can transfer it any time to another provider.
You can also transfer it to any other type of ISA, or even the same type. (Let’s live a little!)
If you transfer from one type of ISA to another, then you count as subscribing to the receiving ISA type. For example, say you transfer from a cash ISA to a stocks and shares ISA. You can now open a new cash ISA without contravening the ‘one type of ISA per tax year’ rule.
If you transfer from a Lifetime ISA to a different ISA type before age 60, you’ll have to pay a nasty penalty charge.
Beware any transfer fees imposed by your current ISA provider.
Transfers into a Lifetime ISA must not exceed the £4,000 current tax year limit.
The golden rule with any ISA move is always to transfer your money. Don’t just go “sod it!” and withdraw your cash in a flounce. If you transfer your ISA to another provider, your assets retain their tax-free status. If you just withdraw the money they don’t.
Find out how to transfer a stocks and shares ISA.
ISA transfer rules for previous years’ ISAs
You have more options with ISAs opened in previous tax years. You can transfer any amount from any of your old ISAs to the same or any other type of ISA.
Any number of your old ISAs can be consolidated into a new ISA of the same or different type.
Any of your old ISAs can be split by transferring a portion of the balance into multiple ISAs of the same or different types.
You can transfer to the same or different providers.
Transferring previous years’ ISAs leaves your current tax year’s allowance untouched.
For example, moving £40,000 from an old ISA into a new ISA still leaves you with a £20,000 ISA allowance for the current tax year.
You could transfer £4,000 into this year’s LISA from an old ISA (of any type), gain the government bonus, and leave your £20,000 allowance entirely intact.
This move maxes out your LISA allowance for the tax year. But you must not then exceed that £4,000 limit by transferring in more cash into the LISA during the current tax year.
As before, make sure you transfer an ISA using the new provider’s ISA transfer process to maintain its tax-free status. Don’t withdraw cash or re-register assets using any other method.
As you can see, your old ISA optionality amounts to a near Bacchanalian free-for-all.
Which brings us to our heavily trailed workaround for the one-type-of-ISA-a-tax-year rule. Hang on to your hat.
Let’s say you wanted to split £20,000 between two new stocks and shares ISAs. You could do it like this:
£10,000 into a new stock and shares ISA.
£10,000 into a new cash ISA.
Transfer £10,000 from previous years’ ISAs into a new stocks and shares ISA.
Repeat as necessary.
Money is fungible, as they say.
Obviously this manoeuvre requires you having, say, an emergency fund of cash tucked away in your old ISAs. But that’s a good idea anyway.
Flexible ISAs let you withdraw cash and put it back in again later the same tax year. Their special sauce is they allow you to do this without grinding down your current tax year’s ISA allowance or reducing how much you’ve saved tax-free.
The following ISA types may be flexible:
Stocks and shares ISA
Innovative Finance ISA
Flexibility is not an inalienable right. The ISA provider has to offer it, and be prepared to deal with the administrative faff. Providers may offer flexible and inflexible versions of the same ISA type.
Here’s an example to show how the flexible ISA rules work:
ISA allowance = £20,000
Contributed so far = £10,000
Remaining contribution = £10,000
You now withdraw = £5,000
In this case can still pay £15,000 into your flexible ISA before the ISA deadline at the end of the tax year because:
Remaining ISA allowance = £15,000 (£10,000 remaining contribution + £5,000 replacement of the withdrawal.)
If your ISA was inflexible then your remaining ISA allowance would be just £10,000. In other words, you couldn’t replace the withdrawn amount. And it would have lost its tax-free status.
Contributions made in the same tax year as withdrawals work in this order:
Replace the withdrawal.
Reduce your remaining ISA annual allowance.
Withdrawals from an old flexible ISA can be replaced in the same tax year. This won’t reduce your current ISA allowance, if the ISA is no longer active.
Flexible ISAs containing assets from previous tax years and the current tax year work like this:
From money contributed in the current tax year.
From money contributed in previous tax years.
Replace previous tax year’s withdrawals.
Replace current tax year withdrawals.
Reduce your remaining ISA annual allowance.
All replacement contributions must happen in the same tax year as the withdrawal.
Some providers say the withdrawal has to be replaced in the same ISA account you took it from.
More quirky than an octogenarian British actor
The ISA rules enable you to put your withdrawn money back into different ISA type(s) with the same provider, if they make that facility available.
Check your provider’s T&Cs. Or send them thousands of emails in BLOCK CAPITALS until they respond.
A flexible stocks and shares ISA allows you to replace the value of cash withdrawn. You can’t replace the value of shares, or other investment types that you moved out of the account.
You can sell down your assets, withdraw the cash, and then replace that cash later in the tax year, and buy more assets with it.
Dividend income should also be flexible in a flexible ISA scenario.
If you transfer your flexible ISA to another provider then check that their product is also flexible.
You may lose the ability to replace withdrawals if you don’t replace them before you transfer a flexible ISA. Again, this is determined by your provider’s T&Cs rather than the rules. (Subject them to a paid Twitter campaign to get an answer on this one.)
If your withdrawals result in your account being closed, your provider can allow you to reopen your flexible ISA in the same tax year and replace the money. That applies to old and new ISA accounts.
Again, check with your provider… (Via a billboard installed outside their office if need be.)
Flexible ISA hack to build your tax-free ISA allowance
Open a flexible, easy access ISA that accepts ISA transfers.
Transfer your non-flexible old ISAs into the flexible ISA.
Your flexible ISA now accommodates the value of the old ISAs – say £40,000.
If your flexible ISA doesn’t pay table-topping interest then withdraw your cash and spread it liberally among the humdinger savings accounts of your choice, or an offset mortgage.
Move your cash back into the flexible ISA by 5 April of the current tax year, and fill as much of the current year’s ISA allowance as you can, too. For instance another £20,000.
In our example, you now have £40,000 + £20,000 = £60,000 tax-free and flexible.
From April 6 of the new tax year: withdraw your cash and liberally spread it.
Repeat as required.
This may look like a vain activity at the moment. But this method builds up a flexible tax-free position that could prove valuable later in life, when you have more cash.
Perhaps it could become a place to shelter and grow your 25% tax-free pension cash. That could be instantly transferred into a stocks and shares ISA, come the day.
Or maybe you’ll sell a business one day, or receive some other windfall, or taxes could go up…
Watch out for the £85,000 FSCS compensation limit (see below). Open a new flexible ISA with a different authorised firm before you go over that line.
What happens if you exceed the ISA allowance?
HMRC should get in touch if you exceed the ISA allowance. You may be let off for a first offence, but otherwise they will instruct your ISA provider on what action to take.
Action is likely to include your extraordinary rendition to an offshore black site where you will be forced to read HMRC compliance manuals for the rest of your life.
Or, alternatively, maybe HMRC will require overpayments and excess income to be removed from your account. And also invite you to pay income tax and capital gains (potentially on all assets in the ISA) from the date of the invalid subscription until the problem is fixed. Eek!
Your ISA provider may also charge you a fee for all the hassle.
You can similarly get into hot water for dropping new money into your ISA as a UK non-resident, or for breaching the one-type-of-ISA-a-tax-year rule, or for breaking the age restrictions.
You can call HMRC on 0300 200 3300 to discuss all this.
Just don’t expect them to admit the Deep State stuff. Open your eyes sheeple. [Editor’s note: we’re joking!]
FSCS compensation scheme
What if your ISA provider goes bust and your money can’t be recovered? In that case the Financial Services Compensation Scheme (FSCS) waits in the wings.
Cash – You can claim up to £85,000 compensation on cash held with each authorised firm.
Innovative Finance – Not covered by the FSCS scheme. You’re on your own.
Watch out for the definition of an ‘authorised firm’. Often multiple brand names sit under the same authorised firm umbrella.
For example, if you have cash at HSBC and First Direct then you’re only covered for £85,000 across both. They are one and the same authorised investment firm.
Investments parked at the same bank should be covered for another £85,000 – on top of your cash.
The Bank of England provides a list of authorised firms and their ultimate parents. We don’t know how often it’s updated.
What happens to my ISA if I move abroad?
You can still put new money into your ISA for the remainder of the tax year when you stop being a UK resident. But you can’t contribute new money again until your residential status changes back.
Your ISA assets will continue to grow free of UK tax. But watch out . Your new country of residence may demand a slice.
You should still be able to transfer ISAs without losing your tax exemption.
Ditto for withdrawing money from a flexible ISA and replacing it.
Ditto for inheriting an ISA.
To be safe, check with your provider before doing anything.
You should also tell your ISA provider when you’re no longer a UK resident. The UK means England, Wales, Scotland, and Northern Ireland. The Channel Islands and the Isle of Man are excluded.
If you split your time between the UK and other territories you can do a residency test. This will determine your status. Fun!
You don’t lose your ISA annual allowance if you’re a Crown employee serving overseas, or their spouse / civil partner.
Well, we’re sure this brief post has cleared everything up… But do let us know in the comments if we’ve missed a bit.
Oh, inheriting an ISA is one gap in our mini-novella above. Just in case you’re planning on inheriting one very soon, check out the government guidance. (Hark! Is that the sound of sawing through brake cables?)
Take it steady,
