Opening a Belgian bank account as a non-resident: what banks require

Two authorities: the NBB for soundness, the FSMA for conduct

A Belgian bank account is mainly accessible to EU residents and to people with a concrete plan in the country, as a euro account opened at a bank licensed by the National Bank of Belgium. The National Bank carries out prudential supervision, the FSMA checks conduct rules towards clients, and the largest banks are also supervised directly by the European Central Bank.

In Belgium the National Bank carries out prudential supervision of credit institutions, while the FSMA checks compliance with conduct rules towards clients. The country's largest banks are also supervised directly by the European Central Bank.

A market dominated by four large banks

KBC, BNP Paribas Fortis, Belfius and ING Belgium hold most personal accounts, alongside smaller banks such as Argenta and Crelan. Brussels, Antwerp, Ghent and Liège host most branches, but opening increasingly happens through an app.

EU residents: the right to a basic banking service

Any consumer legally resident in the Union can request a basic banking service in Belgium, a payment account with a debit card at a capped price. This right does not cover savings or credit, and a bank may refuse on anti-money-laundering grounds.

Outside the EU: why refusals are more frequent

A non-resident living outside the European Economic Area often runs into the requirement of a Belgian address. Banks more readily accept a request for a bank account in Belgium tied to a signed job, studies, a property purchase or a business activity in Belgium.

National register number or BIS number

Banks identify Belgian clients by their national register number. A foreigner not registered with a municipality but with rights or obligations in Belgium receives a BIS number from the Crossroads Bank for Social Security, often asked for at opening.

Documents for a first appointment

A passport or EU identity card, proof of address, a tax number from the country of residence, a CRS self-certification and proof of income form the basis. Depending on the profile, the bank adds, for a non-resident account, a Belgian employment contract, a property sale agreement or university enrolment.

A 100,000 euro guarantee and protection for securities

Deposits are covered by the Guarantee Fund up to 100,000 euros per person per bank. Securities held in custody fall under a separate regime: the Protection Fund pays up to 20,000 euros if financial instruments cannot be returned.

The NBB's Central Point of Contact

Belgian banks report the existence of their clients' accounts to the Central Point of Contact kept by the National Bank. Belgian residents declare their foreign accounts there themselves, while non-residents' tax authorities are informed through CRS.

Bancontact, Payconiq and instant SEPA transfers

Belgian debit cards run on the Bancontact network, accepted throughout the country, and the Payconiq by Bancontact app handles mobile payments. Euro transfers follow SEPA standards, including the instant transfers Belgian banks widely offer.

Before opening an account with KBC Bank

At KBC Bank, present mainly in Flanders and Brussels, the digital onboarding route generally assumes Belgian identification; a non-resident should first check whether opening in a branch is possible and which foreign documents are accepted.

How to choose a bank for a Belgian bank account

The first criterion is language and proximity: the country has a Dutch-speaking area, a French-speaking area and bilingual Brussels, and not every branch offers the same service in each language. A client settling in Antwerp or Ghent does not have the same needs as one living in Liège or Brussels, and the size of the branch network matters.

Next, compare package prices, the quality of the app, card payment limits and the level of support for foreign clients. The large banks generally offer full packages, while smaller institutions rely on simple pricing. Ask each one what it requires from a client without a national register number, because the answer varies from one bank to another.

Finally, think about duration: a bank account in Belgium often serves for several years, sometimes beyond a stay. Check how the bank treats a client who moves, what it charges if the balance stays low and whether it keeps remote access after a departure abroad. A considered choice avoids having to open and then close several accounts in succession.

Steps to open an account in Belgium as a non-resident

Start by clarifying the reason for opening: a job, studies, a property purchase, retirement, a business activity or a family project. This reason guides the choice of bank and the list of documents to provide. Then note your tax details, including the tax identification number of your country of residence, which appears in the CRS self-certification.

Contact the chosen bank, in a branch or through its online channels, and ask for the exact list of documents. At the appointment, show the original of your identity document, your proof of address and income and, if you have one, your BIS number. The adviser may ask about the origin of funds and the intended use of the account.

Once the file is accepted, the bank activates the account and hands over the card and access codes, sometimes by separate post. Make a first test transfer before sending a large sum through it. In practice, timelines depend on the bank and on how complete the file is, and no opening can be promised in advance.

Common mistakes with a Belgian account and reasons for refusal

The most common refusal comes from an insufficiently documented reason. Asking for a Belgian account with no demonstrable link to the country, with no job, studies, property or project, leads the bank to conclude that it cannot assess the risk. Present the context from the start and attach the documents that prove it, rather than waiting to be asked.

Another mistake is supplying contradictory documents, for instance a different address on the passport, the proof and the form. Banks are required to detect inconsistencies and to refuse if doubt persists. Beware also of repeated requests at several branches of the same bank, which leave a trace in its internal system and can complicate the file.

Ask for the reason in writing, correct the file if necessary, then try another bank or, if you are legally resident in the Union, invoke the right to a basic banking service mentioned above. This service remains limited to payments, but it can help a European resident who gets no answer elsewhere.

CRS reporting for a bank account in Belgium and checks

An account in Belgium opened by a non-resident falls under the automatic exchange of information. The bank collects the holder's tax residence and sends the required data to the Belgian tax authority, which then passes it on to the authority of the country of residence. It is therefore prudent to declare the account in your country of residence according to its own rules.

Reporting rules vary from one country to another: some ask you to flag every foreign account, others only the income it produces. Ask your tax authority or an adviser. This text is informational and does not replace personalised advice, especially if your situation links several countries.

Before acting, finally check the current conditions with the bank and the supervisory authorities, because procedures and required documents change. Confirm the deposit guarantee amount, the applicable fees and the closing procedure. With these checks, opening a Belgian account can be prepared calmly.
