A joint bank account is one that you share with one or more people.
It doesn't necessarily have to be your partner or spouse - friends, housemates and business partners might also want to share an account to make managing finances easier.
Opening a joint bank account is often a practical decision - for example, it can make paying household bills easier, and ensure a stress-free way to manage shared income and outgoings. But it also creates a financial link between you and the other account holders.
All of the banks and building societies in the table below let you set up a joint account as either-to-sign (where any account holder can authorise transactions).
We've also shown you those that permit both-to-sign joint accounts (where all account holders must authorise transactions), along with the maximum number of people that can be added to a joint account, and which firms let existing customers convert a sole account into a joint account.
Accounts are listed alphabetically:
Bank of Scotland | 76% | 2 | Yes | No |
Barclays | 70% | 4 | Yes | Yes |
RECOMMENDED PROVIDER First Direct | 88% | 2 | Yes | No |
Halifax | 75% | 2 | Yes | No |
HSBC | 71% | No max | Yes | No |
Lloyds Bank | 74% | 2 | Yes | No |
Metro Bank | 76% | 4 | Yes | No |

Joint accounts can be a neat way to make the most of inflation-busting interest rates.
Banks tend to let you hold just one interest-paying current account in your name alone, but you can open an additional account in joint names.
Bank of Scotland is an exception - you can add 'Vantage' to a maximum three accounts per person (six between two people) to earn interest.
Unlike interest-paying accounts, there's little to be gained by opening multiple cashback current accounts, as banks tend to restrict benefits - for example, Barclays customers can only hold one Rewards Wallet each.
However, a joint account is a good way of getting more value from a packaged account ,as you'll both be covered, but will pay just the same monthly fee between you.
No matter who pays in and who spends what, each account holder is jointly responsible for any debt.
If you've agreed to an either-to-sign joint account, any account holder can increase or decrease an overdraft without the permission of the other(s).
The bank could pursue any account holder for an overdrawn balance, even if they were unaware of it.
Yes, joint accounts create a financial link between you and any other account holders - known as 'financial associates' - meaning prospective lenders may look at their credit report as well as yours when assessing applications.
If you share a bank account with someone who has a poor credit history, it could make it more difficult for you to get credit, even in your own name.
If there's a dispute, you must tell your bank immediately.
After being notified of a disagreement, providers will register the dispute and either freeze the account or switch it to 'both-to-sign' so that it no longer accepts instructions from just one account holder.
This means that debit cards and cheque books are blocked, and access to online or telephone banking is suspended until the dispute is resolved, or you both agree to close the account.
In some cases, direct debits and standing orders are automatically cancelled, so you may be advised to open a new sole account to cover essential bills.
Some providers will let one person close a joint account, as long as there isn't a dispute registered. But otherwise, you'll both need to sign and send an account closure form or visit a branch together.
You won't be able to close an account until any overdraft has been paid off.
Your bank or building society will also need to know how the money will be distributed between you, and what should happen to any standing orders or direct debits.
Remember that details of all financial associations will remain on your credit report unless you tell the credit reference agencies otherwise.
Contact all three agencies - TransUnion, Equifax and Experian - to issue a 'notice of disassociation'. This means that the other account holder's financial circumstances won't affect your credit applications in future.
Providers in England and Wales may freeze a joint account when one person loses mental capacity, unless a power of attorney is already in place to make decisions on their behalf.
This is designed to protect the vulnerable, but it can take several months and a lot of money for a deputy to be appointed by the Court of Protection.
This would involve temporarily blocking debit cards, withdrawals, online banking and even direct debits - only Clydesdale and Yorkshire Banks, Co-operative Bank, First Direct, Nationwide, Post Office, Santander, TSB and Virgin Money told Which? the account would remain in full service for the other account holders.
In Scotland, banks must automatically allow the other account holders to carry on using the account under the Incapacity Scotland Act 2000, provided it was set up on an either-to-sign basis.
In Northern Ireland, practices vary between banks.

The introduction of the personal savings allowance (PSA) in April 2016 means that annual interest from bank and savings accounts is now tax-free up to £500 for higher-rate taxpayers and £1,000 for basic-rate taxpayers.
Where two joint account holders are in different tax brackets, HMRC told us that half of the interest earned is attributed to each account holder, and then set against their individual PSA.
For example, if the account earned £500 in interest, the basic-rate taxpayer's remaining tax-free allowance would be £750, while the higher-rate taxpayer's allowance would drop to £250.
When an account holder dies, money held in joint names usually passes automatically to the surviving account holder, which means that they are still able to access the funds, and probate is avoided.
Under Scottish law, a deceased's share doesn't pass automatically by survivorship to the remaining owner, but the bank may allow them to continue to operate it.
After receiving the death certificate, the bank can transfer the account into the surviving party's sole name, although any existing overdraft facilities may be reviewed.
The tax implications can be less straightforward:
For example, if a son or daughter operates a joint account on behalf of an elderly parent, and never contributed to the account, all of the money will be treated as part of the deceased's estate.
