Shared account for a flatshare in Belgium: what works

A flatshare in Belgium does not need a joint account. It needs one account that carries the direct debits, and a method for splitting everything else. A joint account is a current account opened in the name of several holders, each of them liable for the balance. A shared pot is only a tracking space inside an app, with neither the same rights nor the same risks. bunq, N26 and Revolut set very different limits on their shared products, and for three people renting together in Ixelles or Leuven the best answer is usually the least banking one.

Should a flatshare in Belgium open a joint account?

In most cases, no. On a current account with several holders, each holder is liable for the whole negative balance, including spending they never made. A flatshare whose line-up changes every year has no reason to sign that commitment just to handle rent and two energy bills.

In practice, the banking liability piles on top of one you have already signed. Since 1 September 2018, Wallonia and Brussels have regulated the flatshare lease: a single contract between the landlord and all the flatmates, together with a compulsory flatshare pact signed no later than the day of the lease. A solidarity clause is not required by law, but landlords insert one almost every time, which already makes each flatmate liable for the full rent. Adding a joint account simply multiplies the doors through which a debt can find you.

In eight years working in a branch, the scenario I saw again and again was never theft. It was the sudden departure. One flatmate leaves in June, the energy direct debit keeps hitting an account sitting at minus 340 euros, and the bank claims the balance from the two remaining holders. Neither the flatshare pact nor good faith changes anything, because the bank is not a party to that pact.

What happens if a flatmate leaves mid-lease?

Removing a holder from a Belgian joint account requires the agreement of every holder plus a branch visit or a signed procedure. Until that is done, the person who left stays liable for whatever happens on the account, and they usually find out the day it goes overdrawn. An account in one person's name is sorted out in an evening: the direct debit moves, the standing order is cancelled, nobody signs anything.

Who carries the direct debits without a joint account?

One flatmate, the most stable one on the lease, puts rent and energy suppliers on their own current account. The others feed that account with a standing order dated the 1st of the month, at a fixed amount covering their share of rent plus an energy advance. The holder does take a real cash-flow risk, and that should be said out loud, but it is capped at one month of charges instead of an unlimited overdraft shared four ways.

bunq, N26 or Revolut: which sharing feature is worth it?

None of the three neobanks gives you a free shared account able to carry rent. bunq and N26 both put sharing behind a paid plan, and the Revolut vault is not an account. That is the part product pages never lead with.

Can an N26 Shared Space replace a joint account?

No, for two reasons. The first is pricing: Shared Spaces require an N26 Smart, Go or Metal plan, and the free Standard account does not include them. The second is structural: a Space stays a sub-pocket of the main account, funded by internal transfer. For a flatshare it works as a common piggy bank, not as a payment account.

Is a bunq shared account useful for a Belgian flatshare?

It can be, on two conditions. The main holder's Pro or Elite subscription is due every month, even if the other flatmates pay nothing on their side. And the IBAN is Dutch: for a Belgian resident that is a foreign account, to be reported once to the Central Point of Contact at the National Bank of Belgium and then mentioned every year in the tax return. Two formalities for something Tricount covers for free.

Why is Tricount still the default for flatshares in Belgium?

Because it asks nobody to change bank. Everyone keeps their own account, adds expenses as the month goes, and the app works out who owes what. It is the only tool on this list that still works when one flatmate banks with Belfius, the second with KBC and the third with Revolut.

The app's history is worth knowing. Tricount was founded in Brussels and had 5.4 million users when bunq bought it in May 2022, for a reported 17 million euros. The takeover neither shut the app down nor forced anyone to open a bunq account: it stayed free, and bunq reported 16.4 billion euros of shared expenses running through Tricount in 2024 alone. One detail worth watching: free does not mean without a catch, since the app also feeds bunq's funnel and you will see product offers.

For the repayment itself, the obvious Belgian tool is the Payconiq by Bancontact app, which becomes Bancontact Pay in spring 2026 with no reinstallation needed. A payment request goes out by message and can be settled by up to thirty people, from one Belgian account to another, free of charge.

How do you split rent and bills without falling out?

By separating fixed from variable. The fixed part, rent and energy contracts, runs by direct debit from a single account fed by standing orders. The variable part, groceries, cleaning products, the washing machine repair, goes into Tricount and gets settled every month.

A worked example makes it concrete. Rent of 1 350 euros for three unequal bedrooms, split 500, 450 and 400 euros by floor area, plus a 60 euro energy advance each: every flatmate sets a standing order on the 1st towards the holder's account, of 560, 510 and 460 euros respectively. The holder never has to chase anyone, and the balance on their current account tells them straight away if somebody forgot.

This reasoning holds for a classic flatshare, three or four people who are not a household. For two flatmates who have been a couple for years and plan to buy together, a joint account at a Belgian bank becomes the simplest option again, and that profile is exactly what banks designed it for. The difference is simple: in a couple, shared financial liability is already accepted; in a flatshare, it lands on you by accident.
