Foreign IBAN in Belgium: mortgage, rent and salary

An IBAN starting with LT, DE or NL is perfectly legal in Belgium, and nobody has been allowed to refuse it since 2016. On the ground, three files still get stuck: the mortgage, the rental guarantee and sometimes the salary payment. Here is what works, what genuinely blocks, and how to react.

What is a foreign IBAN, and why does yours start with LT or DE?

A so-called foreign IBAN is an account number whose first two letters point to a SEPA country other than Belgium. The prefix reflects the country that granted the licence to the institution, not the one where you live.

Hence the current map of neobanks available here. Revolut is licensed in Lithuania, N26 in Germany, bunq in the Netherlands. As long as a provider operates from its home country under freedom of services, your account carries its prefix, even if you have lived in Namur for twenty years and hold a Belgian ID card.

One exception changes things: the local branch. Since May 2025, Revolut has issued a Belgian IBAN (BE) to customers living in Belgium who have entered that address in their profile, through its Belgian branch. It is the only major neobank to have done so for retail customers. N26 stays on DE, bunq on NL.

One detail matters on the tax side: an account with a foreign IBAN must be declared to the tax authorities and registered once with the Central Point of Contact (CPC), the register of bank accounts kept by the National Bank of Belgium. A Belgian IBAN takes you out of that formality. We cover the mechanism in our article on neobank savings tax in Belgium.

Can an employer or a public body refuse your foreign IBAN?

No, it is prohibited. Article 9 of EU Regulation 260/2012, in force since 1 February 2016, forbids requiring that an account be held in a given country as long as the IBAN belongs to the SEPA area. The rule applies to employers, health insurance funds (mutuelles), public administrations, energy suppliers, telecom operators and insurers.

The text is clear; enforcement less so. The European Central Bank has tracked the issue for years within its retail payments forum, and the European Commission acknowledges that the practice has not disappeared a decade after the regulation took effect. Refusal rarely comes as an outright "no": it is an online form that only accepts eleven characters after "BE", a payroll system that blocks, a desk officer saying the system will not take it.

You can read the full text on EUR-Lex, the official EU law portal. Two sentences unblock the situation nine times out of ten, and the person opposite you often discovers the rule on the spot.

I ran into this with a Walloon payroll office on a side contract. Their bank details form would not take a 20-character IBAN. The administrator was not acting in bad faith: her tool dated from 2014 and she had never seen anything other than a "BE". One email with the regulation number, a manual entry on her side, and it was sorted in two days.

Can you have your salary paid into a foreign IBAN in Belgium?

Yes, and it is the most common use case. A salary payment is an ordinary SEPA credit transfer: it costs the employer the same, arrives within the same deadlines, and the 2012 regulation bars them from imposing a Belgian account on you.

What varies is administrative friction. From the feedback I collect, a Dutch IBAN goes down slightly better than a German one, with no logic behind it — that is desk habit, not regulation. Since Revolut started issuing BE numbers, its customers no longer hit the problem at all.

The real issue runs the other way: SEPA direct debits for rent, insurance, subscriptions and property tax. Technically, a mandate works on any IBAN in the area. In practice, some Belgian creditors still refuse to register the mandate, and you only find out when the payment bounces.

In practical terms, for everyday use: keep a Belgian account as long as you have sensitive direct debits running. I have seen a home insurance premium rejected on a German IBAN, with the formal notice arriving three weeks later. The problem was never the money — it was sitting in the account. The mandate had simply never been activated.

Can you get a mortgage with a neobank?

No. As of writing, no neobank active in Belgium offers mortgages. Not Revolut, not N26, not bunq, not Wise. The loan necessarily goes through a Belgian bank, a broker or a specialist credit provider.

Revolut launched the product in Lithuania and is working on other European markets, but nothing has been announced for Belgium. A mortgage requires a property valuation, a notarial deed, a mortgage registration and local recovery handling: precisely the kind of activity a pan-European cross-border model covers least easily.

That leaves the awkward question: does your foreign IBAN penalise your application? Not on the principle of approval. But nearly all Belgian banks offer a rate reduction conditional on having your income paid in with them, often bundled with mortgage protection and fire insurance. That reduction is not compulsory, it is commercial — and over twenty-five years, a few tenths of a percentage point add up to thousands of euros.

A friend built his file last year with two lenders. The first offered a clearly lower rate provided his salary landed in an account opened with them; the second attached no condition but started higher. He ran the numbers over the full term, opened a Belgian account, and kept his neobank for everything else. That is not IBAN discrimination, it is the business model of Belgian mortgage lending.

Can you set up a rental guarantee from a neobank?

No, and this is the most concrete blocker for a tenant. A rental guarantee on a blocked account (compte bloqué) must be opened in the tenant's name at a financial institution offering the service. Belgian banks do — BNP Paribas Fortis, KBC, CBC, Belfius, ING, Triodos. No neobank offers it.

Two rules protect the tenant and are far too little known: the bank cannot charge for opening this account, and it cannot require you to have your salary paid in as a condition. If you are offered a "current account plus salary domiciliation" package as a prerequisite, that is out of bounds.

Ceilings depend on the Region where the property is located, and the gap is real:

Each Region also runs a support scheme for households below certain income thresholds: the Fonds du Logement in Wallonia, BRUGAL in Brussels, the Vlaamse Huurwaarborglening in Flanders. These are interest-free loans and they, too, go through a Belgian bank.

The order of operations matters. I watched someone sign a Brussels lease expecting to open the blocked account "within the week", with a neobank as their only bank. A Belgian account had to be opened in a hurry, with the identity verification delays that come with it, and the landlord was starting to lose patience. If you are flat-hunting, open the Belgian account before you sign.

What should you do when your IBAN is refused?

Five steps, in this order, and none of them costs money. The first one settles almost every case.

1. Write, do not call. An email quoting Article 9 of EU Regulation 260/2012 and asking for your IBAN to be registered. Keep the record.
2. Escalate one level if the answer is negative: customer service, then the organisation's complaints department, in writing.
3. Report it to the FPS Economy. The Directorate-General for Economic Inspection handles this type of breach, through the ConsumerConnect contact point. Free, online.
4. File the case on Accept My IBAN, the industry platform backed by several European providers, which feeds the Commission's work. Almost 3,500 cases were reported there between February 2021 and September 2023.
5. Refer the matter to Ombudsfin if the dispute involves a financial institution rather than an ordinary creditor.

The classic mistake is to give in straight away and open a Belgian account because it feels simpler. Sometimes it is. But every unreported refusal sustains the fiction that the problem has gone away, while the Commission observes the opposite. Two minutes of reporting is what moves the needle.

Which setup actually works in Belgium?

A Belgian bank for the heavy files, a neobank for everything else. This is not a soft compromise: it is the only setup that covers the mortgage, the rental guarantee and foreign exchange costs at once.

State of play in summer 2026. Offers change quickly: check the terms in force when you decide.

Who this suits — and who it does not. If you are planning neither a property purchase nor a move within three years, a neobank as your main account works well, and Revolut's Belgian IBAN removes the last common friction. If you are house-hunting or building a mortgage file, keep or reopen a Belgian account: you will need it, and doing it under time pressure is worse.

In short

A foreign IBAN is nothing irregular in Belgium: EU Regulation 260/2012 has prohibited refusing it since February 2016, and a refusal can be challenged in writing and then reported free of charge to the FPS Economy. Salary and direct debits go through without any objection in principle, with occasional rejections to unblock. The two real walls lie elsewhere: no neobank writes mortgages here, and none opens a blocked account for a rental guarantee — two months' rent maximum in Wallonia and Brussels, three in Flanders. The setup that holds is a Belgian bank for those two files and a neobank for daily life. To pick which one, the comparison tool puts the offers side by side and the quiz gives a recommendation in two minutes.
