Joint savings accounts

A joint savings account is one savings account shared by two people. Nationwide, which offers joint savings accounts, describes it simply: "A joint savings account is where 2 people share 1 savings account"¹. Both holders can usually pay money in, and depending on how the account is set up, either or both of you can take money out. Couples often use one to save towards a shared goal such as a deposit, a wedding or home improvements, and some people use one with a family member to manage shared money.

The two things that most often catch people out are tax and protection. Interest on a joint account is normally split equally between the holders for tax purposes, so each of you declares your half². And the Financial Services Compensation Scheme (FSCS) protects each eligible holder up to £120,000 per authorised firm, which means a joint account with two holders is protected up to £240,000 in total³. But that £120,000 is per person per banking group, not per account, so money in your sole accounts with the same group counts too⁴.

What a joint savings account is and how it works

A joint savings account works much like any other savings account, with the key difference that two people own it together. MoneyHelper, the free government-backed money guidance service, explains that a joint account normally allows two or more people to receive payments, transfer money and manage the account, depending on the bank². With savings, the arrangement is usually simpler: two named holders pay in and build the balance together, and the interest is calculated on the whole balance.

Joint accounts are commonly opened by couples, but people also open them with other family members, for example to manage shared household money. Citizens Advice Scotland notes that you can open a bank account jointly with other people, for example to manage household bills or with a spouse or civil partner⁷. The same principle applies to savings: the account belongs to both of you, and each holder's rights over the money depend on how the account is set up and, if things go wrong, on rules about ownership that differ across the UK.

One point worth understanding early is that a joint account is a single pot, not two separate ones. Under the deposit protection rules, a depositor's share of a joint account is calculated by dividing the total balance equally between the number of account holders⁸. That equal split matters for compensation if a bank fails, and, as the next sections explain, it also shapes how the interest is taxed and who is treated as owning the money if you separate.

If you are weighing up the different kinds of savings account, from easy access to fixed rate, our guide to types of savings account sets out how each one works.

Who can open one and what the provider asks for

Each provider sets its own eligibility rules, but the requirements are broadly similar across the market. Nationwide, for example, requires both account holders to be UK residents aged 16 or over¹. Both of you will need to prove your identity and address, in the same way as when opening a sole account, and our guide to opening a savings account explains what documents providers typically ask for.

Not every savings account accepts joint applicants. Which? found in February 2026 that some providers only make their accounts available to sole applicants, and of the top-paying easy access accounts that were available to joint applicants, one required the account to be opened in a single name first, with the second holder added later through a separate process⁶. So it is worth checking the account's terms before you apply, rather than assuming every account works the same way.

How you apply depends on the provider. Nationwide says you can open a joint savings account online in its app or internet bank, or at any of its branches, and that at least one holder must already have accounts with it¹. Other providers have their own routes, including by post or over the phone.

There are also savings schemes aimed at individuals that couples can still use side by side. StepChange notes that if you and your partner have a household award of tax credits or Universal Credit, you will each be allowed to open your own Help to Save account⁹. Help to Save is a government-backed scheme with a bonus on what you save, and it is held individually rather than jointly. Our Help to Save guide explains how it works.

Withdrawals and access: either to sign or both to sign

The most important practical question with any joint account is who can take money out. Most joint accounts are set up as "either to sign", which means each account holder can give payment and withdrawal instructions independently¹⁰. nidirect, the Northern Ireland government service, puts it plainly: each account holder can withdraw money without asking the other person¹¹.

That arrangement suits most couples saving towards a shared goal, but it carries an obvious risk: either of you can empty the account at any time, without the other's consent. Some banks offer an "all to sign" arrangement instead, which means all account holders have to make decisions jointly, though MoneyHelper notes this usually limits account management to a branch². If control over the money matters to you, for example when saving with someone outside your household, it is worth asking a provider whether an all-to-sign option exists before opening the account.

Access rules also interact with the type of savings account you choose. An easy access account lets you withdraw whenever you like, a notice account requires a waiting period, and a fixed-rate bond locks the money away until maturity. Those rules apply to the joint account as a whole, regardless of which holder asks for the withdrawal.

A joint account cannot be a cash ISA

A cash ISA is a savings account where interest is paid free of income tax, but it cannot be held jointly. Which? states the position directly: "You can't have two account holders on a cash Isa, so couples can't use them to save together"⁶. Each ISA must have one account holder, who has their own ISA allowance.

This does not stop a couple saving together tax efficiently. Each of you can open your own cash ISA, and between you hold twice the allowance. Nationwide notes that for joint accounts, each account has its own £20,000 annual cash limit, shared between the holders, in addition to the £20,000 limit across sole accounts¹. In other words, a couple can shelter money in two separate ISAs, or hold a joint ordinary savings account alongside them.

The trade-off is that interest on a joint ordinary savings account is taxable, split between the holders, while interest in a cash ISA is not. Whether that matters depends on how much interest you earn and your personal savings allowance. Our comparison of cash ISAs versus ordinary savings works through the sums.

Tax on joint savings: interest split 50/50

Interest earned in a joint account will usually be split equally between each person, with tax only due if a share is above the annual allowance². Each holder then applies their own personal savings allowance and pays any tax they owe separately. Which? describes the same rule: tax on interest earned would typically be split 50:50 between you¹². HMRC's own form P53Z confirms the mechanics: "If you have a joint account only enter your share, usually 50%, of the interest received"¹³.

Each of you then pays tax on your half according to your own circumstances. Interest above your personal savings allowance is charged at your usual rate of income tax, whether that is 20%, 40% or 45%¹⁴. The personal savings allowance itself, and the starting rate for savings that can help lower earners, are explained in our guide to how tax on savings interest works.

The equal split can work in a couple's favour when one person is a non-taxpayer or has unused allowance, and against you when both holders are higher-rate taxpayers. It is also worth knowing that if your bank or building society tells HMRC you have more than £10,000 in savings interest, HMRC will send you a notice to file a tax return, and you must tell HMRC how much interest you earned on a Self Assessment return¹⁵.

Two changes are on the horizon. From 6 April 2027, the tax rate on savings interest is set to rise by two percentage points: to 22% for basic-rate taxpayers, 42% for higher-rate taxpayers and 47% for additional-rate taxpayers¹⁶. Which? has reported that this will push more savers over the threshold at which tax becomes due¹⁷. If all the money in a joint account actually belongs to one person, you will need to let HMRC know that, for it to treat all the interest and the possible tax bill as that person's responsibility¹².

Deposit limits: per account or per holder

When a savings account has rules such as a maximum deposit or a maximum balance, those rules apply to the account, not to each holder separately. Nationwide states this plainly: "Account rules like maximum deposits or balances apply to the savings account, not each account holder"¹. So if a joint account has a £50,000 balance cap, the cap is £50,000 for the pair of you, not £50,000 each.

Some providers apply personal limits differently. NS&I, the government's savings arm, applies a personal holding limit to some products, and for its Direct Saver it states that half of the balance in a joint account counts towards each account holder's personal holding limit¹⁸. The same principle applies to its Green Savings Bonds, which can be held jointly¹⁹. If you are saving large amounts, check the product's terms for how joint holdings are treated.

The £20,000 ISA limit works differently again, because an ISA cannot be joint. As noted above, a joint ordinary savings account has its own £20,000 annual cash limit per account, shared between the holders, and this sits alongside each person's £20,000 ISA limit across their sole accounts¹.

Who owns the money if you separate

What happens to the money in a joint savings account after a break-up depends on where in the UK you are and whether you were married or in a civil partnership.

In England and Wales, money in joint accounts belongs to whoever paid it in, but a non-contributing partner could claim a share if they can prove the account was intended as a shared fund. If you were married or in a civil partnership, money belongs to both of you equally¹⁰.

In Scotland, any money a married couple or civil partners have in a joint savings account opened during the marriage or civil partnership belongs to the account holders equally, though if you can prove you paid in more money, you might be able to claim more¹⁰.

In Northern Ireland, money in a joint savings account after a break-up belongs to each of you equally, unless a court decides differently¹⁰.

Joint savings can also be treated as yours in other official assessments. If you jointly hold capital such as a joint savings account, you will usually be treated as having half of the money when your finances are assessed for care and support at home²⁰, and if you have a partner aged 60 or over, you may be able to ignore 50% of your joint savings in a means test for residential care or hospital residence²¹. Our guide to how savings affect benefits covers the treatment of joint money in benefit claims.

What happens when one account holder dies

If an account holder passes away, the joint account will continue in the names of the remaining holders². In practice, the provider will ask for the death certificate. Nationwide, for example, states: "Once we receive the death certificate, we will change the account to the other account holder's name"¹. NS&I says the same in its terms: if one account holder of a joint account dies, the surviving account holder will get ownership of the account¹⁹.

The surviving holder does not necessarily keep everything free of other claims, though. NS&I's Direct Saver terms state that if the last surviving account holder dies, no more deposits can be accepted, the balance becomes part of the account holder's estate, and the account continues to earn interest¹⁸. And in Scotland, the rules around estates are more complicated: Citizens Advice Scotland explains that if a joint account was held by spouses or civil partners and both contributed to it, it is presumed the money is held equally, so half the balance on the date of death is presumed to belong to the person who died. A surviving holder might have to prove they paid in all the money for the account to be excluded from the deceased's estate²².

Inheritance tax can also arise. MoneyHelper notes that unless you were married or in a civil partnership, you might have to pay tax on some or all of the money in the account when the other holder dies². Spouses and civil partners are treated differently, and our section page on personal tax explains the rules around estates.

Removing a holder or changing the account

Circumstances change, and providers have processes for removing a holder from a joint account. Nationwide notes one detail worth knowing: if your savings account has a nominated account for withdrawals, it will not automatically remove or change this when a holder is removed¹. A nominated account is the external bank account that withdrawals are sent to, so if it points to the departing holder's account, you need to ask for it to be changed rather than assuming the provider will do it.

If you are separating, the practical steps usually involve closing the joint account and dividing the balance, or moving the money into sole accounts. Which? has guidance on financially separating from an ex-partner, including what happens to joint accounts¹⁰. If the relationship ended some time ago, also be aware of the credit file point covered below: closing a joint account does not remove the financial link between you.

Switching works for joint accounts too. The Current Account Switch Service works for joint accounts provided you are switching to another joint account and all account holders agree, and you can also switch a sole account to a joint account elsewhere². Our guide to switching savings accounts covers the process.

FSCS protection: £120,000 per person, £240,000 for two

The Financial Services Compensation Scheme protects deposits in UK banks, building societies and credit unions authorised by the Prudential Regulation Authority (PRA), and the limit is £120,000 per eligible person, per authorised firm²³. Joint accounts are eligible for FSCS protection up to the same limit of £120,000 per eligible person²⁴. The Bank of England gives the worked example: "In other words, a joint account with two holders would be protected up to £240,000"³.

FSCS assumes the money in a joint account is split equally between the holders unless evidence shows otherwise²⁶, and its protection checker makes the same assumption for a joint account with two account holders⁴. The limit rose from £85,000 to £120,000 on 1 December 2025²⁷. The Building Societies Association confirms the same figure applies at building societies: the maximum amount covered for a couple would be £240,000²⁶.

Three details decide how much protection you actually have:

• The limit is per person, per authorised firm, not per account. If you have an individual account and a joint account within the same banking group, the £120,000 limit applies across all these accounts, not to each separate account⁴. Banks in the same group that share a banking licence are treated as one bank²³.
• Your half of the joint account counts towards your own limit. FSCS protects each of you, whatever the number of account holders, up to £120,000 in total across all accounts you hold with that firm²⁸.
• Business partnerships are treated differently. If joint account holders are acting as business partners, the partnership is only entitled to a single claim of £120,000, not one claim per partner²³.

To protect more than £120,000, you can spread money among deposit takers with different authorisation numbers, with each holding no more than £120,000 of yours⁴. FSCS also protects certain qualifying temporary high balances up to £1.4 million for six months from when the amount was first deposited, for example after a house sale²³. Our narrow guide to FSCS cover on joint savings accounts goes deeper, and temporary high balance protection explains the six-month rule.

If a bank fails, FSCS will pay compensation within seven working days, though more complex cases, including temporary high balance claims, take longer²³. FSCS cannot protect money held with e-money or payment services firms, but if a savings platform or aggregator deposited your money with a regulated bank that then fails, it is likely that FSCS will protect it, with the same compensation limits as for other bank accounts⁴. Our guide to cash savings platforms explains how they work.

You can check whether a provider is covered using the FSCS protection checker²⁹.

Joint accounts, credit files and debts

A joint savings account itself has no impact on your credit score or history¹. But joint accounts in general can create financial links that do. Opening a joint bank account adds a financial link to the other person, so companies look at both credit histories, and a poor history on their side might lower your chances of being accepted². MoneyHelper advises only opening a joint bank account with someone you trust, as it could damage your credit score if they have poor credit³⁰.

Two further points matter. Closing a joint account will not remove the link to the other person from your credit file; you can ask credit reference agencies for a "notice of disassociation" if you have no other financial connection². And Shelter notes that a past joint account could affect your credit file and make it harder to open a bank account and borrow money³¹.

Joint money can also be reached by creditors. In Scotland, if a creditor takes money from a joint account, the creditor is entitled to the full amount in certain cases, including where only the account holder in debt paid money in, or where the debt was incurred jointly³². Where the account is in two names and only one person owes the debt to HMRC, HMRC will say 50% of the money in the account can be taken³³. And if one holder is made bankrupt, half of any credit balance in a joint account is paid to the official receiver or trustee³⁴.

Free help

Several free, impartial services can help with joint savings questions. MoneyHelper, the government-backed money guidance service, covers joint accounts, tax on savings interest and how FSCS protection works². Citizens Advice can help with banking questions, debts and what happens to accounts after a death²². StepChange, a debt advice charity, advises on joint accounts and bankruptcy³⁴. The FSCS runs the protection checker and publishes its own guides to what is covered²⁹. If you have a complaint about a savings provider that it will not resolve, the Financial Ombudsman Service can look at it, and our guide to consumer protection explains how to complain.
