OmniTrust has provided a comprehensive guide to help non-residents in Belgium understand how to declare their taxes online. You can read the full article by clicking here, or see a brief summary below.
Non-residents earning income from Belgian sources, such as salaries, pensions, or rent, are subject to Non-Resident Tax (NRT), calculated like personal income tax. This applies to individuals residing or headquartered abroad who are not registered with Belgium’s national register. Non-residents with Belgian income, whether living abroad or staying temporarily in Belgium for work or studies, must file a “non-resident tax declaration.”
The NRT applies to non-residents who receive income from Belgian sources and either reside abroad or stay in Belgium temporarily (for work, studies, or other purposes). If you fit this category, you must submit a non-resident tax declaration.
For NRT purposes, legal cohabitants are treated as married persons. To be recognised as legal cohabitants, two individuals must file a declaration at their local municipal office, meeting the same legal criteria as those set by Belgian law. Foreign cohabitation agreements must also meet Belgian standards. Typically, married couples and legal cohabitants submit one joint declaration unless specific circumstances apply, such as the year of marriage, cohabitation declaration, divorce, separation, or the death of a partner. In cases where only one partner has NRT income, and the other partner has foreign or exempt income exceeding €12,550, separate declarations are required.
Parents with legal entitlement to their minor children’s property must include taxable income from such property in their declarations. In cases of joint entitlement, each parent must declare half of the taxable income. If one parent has sole entitlement, they must declare the entire income. However, child labour or child support income is reported in the children’s name, not the parents. Additionally, maintenance payments for non-resident children are excluded from the tax declaration.
Non-residents must declare all income received from Belgian and foreign sources. Belgian income that is exempt from tax and foreign income is not subject to non-resident tax. For real estate, if you or your spouse own rental property in Belgium, you must declare all properties. Real estate income is based on the Net Cadastral Income (NCI) rather than actual rent. If the total NCI is below €2,500 per year for each spouse, no tax is due, but you must still file a declaration and indicate “nil” on the form.
Non-residents must submit their tax declaration online via MyMinfin by November 22, 2024. A joint declaration requires both spouses’ connections. Those without MyMinfin access can submit a simplified version using a Belgian national number, which doesn’t allow changes after submission. Once submitted, you will receive confirmation of whether tax is owed or a refund is due. Be sure to complete the preparatory document before filing the declaration.

Luc is a Director of VAT at Kreston VDN in Belgium and a Certified Tax Adviser ITAA.
Luc is relatively new to the network, having joined Kreston VDN in January 2021, although he is very well known and respected in Belgium as a result of many years in the profession, including a Big 4 firm, in the Tax Administration in Brussels and for his profile as a result of publishing a large number of books on international and domestic VAT matters and having presented and lectured on the subject.
Luc wanted to join the leadership team given his experience in previously seeing an international network move from being a group of local specialists to a collaborative team with an international VAT and other indirect tax network. He knows what we need to do to continue to grow and wants to help us achieve our goals.

A few years ago, the Belgian government introduced a new tax regime for holders of investment accounts with a combined value of more than €500,000. However, this tax was abolished when a judgement by the Belgian Constitutional Court found it discriminatory. On 2 November, the newly elected government has proposed a new tax on investment accounts, broadening its scope to address the concerns of the Constitutional Court.
Personal scope
Both physical and legal persons are subjected to the new tax on investment accounts. Investment accounts held by a legal structure (including a trust or foundation) are deemed to be held by the person who qualifies as the founder of that structure.
The tax applies to both residents and non-residents (physical persons as well as legal persons) holding a Belgian investment account, unless a double tax treaty prevents Belgium from levying tax on the assets of non-residents.
Material scope
The tax is aimed at investment accounts with an average value of more than €1 million during a given period. All financial assets held in the investment account are taken into account to determine the average value of the account, as opposed to the previous tax on investment accounts that excluded certain financial products. Life insurance contracts with an underlying investment account also seem to be in scope.
Shares are excluded, provided that they are not held in an investment account (e.g. registered shares) unless the anti-abuse rule applies (see section on anti-abuse rule).
Since the tax aims to subject the investment account to tax (and not the person holding it), it is not necessary to divide the value among all accountholders. However, this could lead to some strange consequences.
Tax rate
The investment accounts in scope are subjected to a yearly tax of 0.15% on the average value of the account, calculated based on its value at quarterly reference dates (31 December, 31 March, 30 June and 30 September).
Exemptions
Exemptions would apply for certain financial companies such as banks, insurance companies, pension funds, and so on.
Anti-abuse rule
A refutable presumption applies that splitting up accounts, converting financial assets and transferring assets to a foreign legal person are done with the intention to evade tax. Such actions, taken as from 30 October 2020 (i.e. the day that the initiative was leaked in the Belgian media), are neglected for purposes of the investment account tax.
Conclusion
Although the new tax on investment accounts has some similarities to the old one, the scope is much wider since it applies to physical persons as well as legal persons (both residents and non-residents). The first reference period will begin on the first day after publication in the Belgian Official Gazette (expected at the beginning of 2021) up to 30 September 2021.
