Taxes in Belgium in 2026 for expats and businesses

Belgium tax rates in 2026: the short version

Belgium takes a bigger share of a salary than any other developed country. According to the OECD (Organisation for Economic Co-operation and Development) report Taxing Wages 2026, the tax wedge - taxes and contributions as a share of what the employee costs the employer - for a single worker on the average wage in Belgium was 52.5% in 2025. That is the highest in the OECD, where the average is 35.1%.

Until recently the country was far gentler on capital: a private investor's gains on shares under normal management of private wealth were not taxed at all. That era ended on 1 January 2026. The law of 6 April 2026, published in the official gazette Moniteur belge on 21 April, introduced a 10% tax on gains on financial assets, crypto included, retroactively from the start of the year.

All amounts are in euros. Income of 2026 is declared in 2027, which Belgian documents call tax year (aanslagjaar / exercice d'imposition) 2027 - so the same rates appear under different years.

Belgium is a federation: tax on buying property, inheritance tax and car taxes are set by its three regions - Flanders, Wallonia and Brussels. Income tax, VAT and corporate tax apply nationwide.

Who is a tax resident of Belgium

Belgian tax law has no 183-day rule. Residence depends not on the calendar but on where the family home or centre of economic interests is, which makes it harder to shed than in countries that count days.

Under the 1992 Income Tax Code (Wetboek van de inkomstenbelastingen, WIB 92 / Code des impôts sur les revenus, CIR 92), a resident is someone whose domicile - the actual permanent home - is in Belgium or, failing that, whose centre of income and assets is there. A tax resident pays tax on worldwide income, a non-resident only on Belgian income.

The practical takeaway: as soon as a family rents a flat and registers with the municipality, Belgium treats it as resident from that day, even if the move happened mid-year. The reverse also holds: deregistering on departure does not help if the family stays in Belgium.

If two countries both claim residence, their double tax treaty decides using tie-breakers - permanent home, centre of vital interests, nationality. Why 183 days is not always decisive is covered in our article on tax residence in 2026.

A residence permit plus municipal registration almost always means tax residence. The route from a residence permit to a passport is on the page about Belgian citizenship by naturalisation, and relocation conditions are in our Belgium overview.

Belgium tax residency rules: residence without a 183-day rule

Belgium has no 183-day rule. You become resident through the family home or, if there is none, through a centre of income and assets managed from Belgium. That is how Article 2 of the Income Tax Code 1992 works.

Registration at a municipal address creates a presumption of residence: the tax office treats you as resident until you prove otherwise. The Belgian code looks at the dinner table, not the calendar: where the family eats, residence follows. A resident pays 25-50% plus the municipal surcharge on worldwide income, a non-resident only on Belgian income.

The law does not stop you from confirming the status on your own. But mistakes cost more: a forgotten municipal registration or a family left in Brussels keeps you resident and taxed at up to 50% on worldwide income. Murblz support removes these risks: we review the ties, prepare the deregistration and evidence, and obtain a residence certificate from the new country. We guarantee professional work and a transparent process, and in most cases a result on the first filing.

What is the income tax rate in Belgium and how much of a salary is left

Belgium's 50% rate starts at 51,070 euros of taxable income a year. By comparison, in neighbouring Germany and France the top 45% rate kicks in at incomes several times higher. So the top rate here hits not millionaires but an ordinary well-paid professional.

The scale is progressive: each rate applies only to the slice of income within its band. The thresholds are indexed by the Federal Public Service Finance (FOD Financiën / SPF Finances), Belgium's tax authority.

Tax-free allowance. The first 11,550 euros of 2026 income are untaxed: the personal income tax reform law of 15 July 2026 (published on 29 July 2026) raised the amount from the indexed 11,180 euros, retroactively from 1 January. It will rise in steps until tax year 2031 and is higher for dependants; for pensioners and benefit recipients the increase is offset elsewhere, so working people gain most.

Municipal surcharge. On top of federal tax, the municipality (gemeente / commune) levies its own surcharge of 0 to 9% of the tax, about 7% on average. It follows the registered address on 1 January after the income year.

Spouses. Couples file jointly, but each income is taxed separately. If one spouse earns little, up to 11,780 euros of the other's 2026 income can be shifted to them (the marital quotient, huwelijksquotiënt / quotient conjugal), or up to 12,790 euros if both spouses are 66 or older. The law of 15 July 2026 halves this relief by 2030 and phases it out over 20 years for couples aged 66 and over.

Worked example: what is left of a 4,500-euro salary

A worked example: a single employee without children, 54,000 euros gross a year (4,500 a month, excluding the 13th-month bonus and holiday pay), municipal surcharge 7%. Employees automatically deduct flat-rate professional expenses: 30% of income after social security, capped at 6,070 euros for 2026.

Out of 54,000 euros gross, tax and contributions take about 19,400 euros, almost 36%. On top, the employer pays its own contributions of about 25-27%, so the full cost of this employee to the company is roughly 67,000-69,000 euros. A special social security contribution is also withheld: 9.30 to 60.94 euros a month depending on household income.

Of every pay rise at this level, less than half reaches the employee. Tax is withheld monthly (bedrijfsvoorheffing / précompte professionnel) and settled through the return.

How much social security employees and the self-employed pay in Belgium

Employee social security in Belgium has no ceiling: 13.07% is withheld from 3,000 euros a month and from 30,000 euros a month alike. In Germany, by contrast, pension and health contributions stop at an annual cap, so for high salaries the Belgian burden is noticeably heavier.

The employer pays about 25-27% of gross on top; the exact rate depends on the sector and the size of the company. These contributions are what puts Belgium at the top of the OECD ranking for taxes on labour.

The self-employed (zelfstandigen / indépendants) and directors of their own companies pay contributions themselves through a social insurance fund chosen at registration. The 2026 rates are set by the National Institute for the Social Security of the Self-Employed (RSVZ / INASTI).

Each fund adds its administration fee on top. The annual maximum for a main occupation is about 20,400 euros (4 × 5,103.05), reached at roughly 110,000 euros of income - a rare advantage over salaried work, where contributions never stop.

Provisional contributions are based on income from three years earlier and recalculated once the actual income is confirmed, so with growing income a large top-up bill often arrives two or three years after starting. The contributions reduce taxable income.

Workers posted from another EU country can stay in their home system for a time with an A1 certificate under the EU coordination rules. The A1 is not issued to employees of Russian companies, so for work in Belgium contributions are usually paid in Belgium from the first month.

What are the corporate tax and dividend tax rates in Belgium

A small Belgian company pays 20% instead of 25% on its first 100,000 euros of profit, but from 2026 the price of that discount is paying a director at least 50,000 euros a year. The threshold used to be 45,000 euros; the increase was introduced by the personal income tax reform law of 15 July 2026, and the threshold will be indexed from 2027 income.

The standard corporate income tax rate (vennootschapsbelasting / impôt des sociétés) is 25%. The 20% rate applies to companies that are small under the Code of Companies and Associations, if at least one individual director is paid at or above the threshold - or at least the company's taxable profit, if that is lower. From 2026, benefits in kind valued at flat rates (car, housing, heating) can make up no more than 20% of that salary.

Dividends to an individual are taxed at 30% at source, usually as a final tax for residents. The first 833 euros of share dividends in 2026 are exempt: the amount has been frozen until 2030, and the tax withheld on it is refunded through the return. A company receiving dividends from a subsidiary in which it holds at least 10% generally does not pay tax on them, thanks to the participation exemption.

For owners of foreign companies another rule matters more - the so-called Cayman tax (kaaimantaks / taxe Caïman). Income of trusts, foundations and companies in jurisdictions where they are taxed at less than 15% is treated as received directly by the resident founder. After the move a foreign holding may save nothing, yet it must be disclosed at once. More on these rules is in our section on controlled foreign companies.

A Belgian company can be set up without the director moving, but the tax authority checks where it is really managed from. Details are on the pages about company registration in Belgium and business accounts in Belgium.

What is the VAT rate in Belgium in 2026 and when to register

Since 1 March 2026 a night in a Belgian hotel carries 12% VAT instead of 6%. Of the increases in the budget agreement, those for hotels, campsites and pesticides went ahead, while the planned rises for takeaway food and concert tickets were withdrawn after objections from the Council of State (Raad van State / Conseil d'État), the supreme administrative court that also advises on draft laws.

The standard VAT rate (btw / TVA) is 21%, the same as in the Netherlands and higher than in Germany (19%) and France (20%). The reduced rates are tied to specific lists in the VAT Code.

Small business threshold. With turnover of up to 25,000 euros a year excluding VAT, the small business exemption scheme (vrijstellingsregeling / régime de franchise) applies: no VAT on invoices and no VAT returns, but no recovery of input VAT either. The 25,000-euro threshold has not changed since 2016; a phased increase to 30,000 euros is under discussion in parliament. Since 2025, small businesses from other EU countries can use the Belgian exemption if their total EU turnover is up to 100,000 euros.

E-invoicing. Since 1 January 2026, all VAT-registered businesses established in Belgium must invoice one another only in a structured electronic format through the Peppol network, a pan-European standard for exchanging invoices between accounting software. A PDF sent by email no longer counts as an invoice for domestic business-to-business (B2B) transactions. Fines are 1,500 euros for a first breach, 3,000 euros for a second and 5,000 euros for each further one.

VAT returns are filed monthly or quarterly; the quarterly regime is available to businesses with turnover of up to 2.5 million euros a year.

Are there tax breaks in Belgium for expats, IT specialists and freelancers

Belgium's main tax break for newcomers is the regime for inbound professionals: up to 35% of pay can be paid as a tax-free reimbursement of expenses. From 2025 the entry threshold was cut from 75,000 to 70,000 euros gross a year, and the 90,000-euro cap on the allowance was scrapped. This was done by the law of 18 December 2025, retroactively from 1 January 2025.

Officially it is the special tax regime for inbound taxpayers and researchers (bijzonder belastingstelsel voor ingekomen belastingplichtigen en onderzoekers / régime spécial d'imposition pour contribuables et chercheurs impatriés). There is no flat rate: the saving comes from taking about a third of the package out of tax.

The inbound regime lasts 5 years and can be extended for another 3. It concerns income tax only: it does not change the social security rules.

Freelancers and sole traders. A self-employed person in Belgium - in effect a sole trader - pays income tax on the same 25-50% scale on profit after expenses, plus 20.5% social security. There is no simplified turnover tax of the kind Georgia offers. So at profits of several tens of thousands of euros a company with the 20% rate is worth modelling, though it needs a director's salary of at least 50,000 euros and company accounts.

Digital nomads and retirees. Belgium has no visa or tax regime for remote workers, no breaks for foreign retirees and no Swiss-style lump-sum taxation. Living in Belgium while working remotely for a foreign company means residence and tax under the normal rules.

How Belgium taxes shares, crypto, property and inheritance

The first 10,000 euros a year of gains on shares, funds and crypto remain untaxed for a Belgian resident, but everything above that has been taxed at 10% since 2026. By comparison, Germany taxes capital gains at 25% plus the solidarity surcharge and France at 31.4%.

The new tax on gains on financial assets was introduced by the law of 6 April 2026. It applies to transactions from 1 January 2026, and all gains built up until 31 December 2025 are exempt: the asset's value on that date becomes the starting price. The tax covers securities, derivatives, some insurance contracts, crypto-assets, currencies and investment gold, but not jewellery.

Banks and brokers in Belgium have been withholding the 10% themselves since 1 June 2026. The withholding is final: once it has been applied, the gain does not have to be declared. Opting out and reporting in the return instead is more convenient when using the 10,000-euro allowance or offsetting losses.

Crypto. Until 2026, crypto gains under normal management of private wealth were untaxed. Now they are taxed at 10% with the same 10,000-euro allowance, while speculation is still taxed at 33%. The line between normal management and speculation is not numerical: trading frequency, borrowed money and complexity decide. Other countries are compared in our article on crypto and taxes when relocating.

Dividends and interest. 30% is withheld. Interest on regulated savings accounts at Belgian banks is exempt up to 1,020 euros per taxpayer in 2026, with 15% above that. The exemption has been frozen until 2030.

Tax on securities accounts. If the average value of a securities account over the year reaches 1 million euros, 0.15% of that value is due every year (jaarlijkse taks op de effectenrekeningen / taxe annuelle sur les comptes-titres). Residents' foreign accounts are covered too. Belgium has no general wealth tax.

Residents must list all foreign accounts, securities accounts included, in their return and report them to the Central Point of Contact of the National Bank of Belgium (Centraal Aanspreekpunt / Point de contact central) - from the first return after the move, including accounts opened before relocating.

Property: buying, owning, renting out, selling

Buying an existing home triggers registration duty (registratiebelasting / droits d'enregistrement), and its size depends on the region more than on the price. The gap between a first home in Flanders and an investment flat in Brussels is sixfold.

New buildings carry 21% VAT instead. The reduced rates require owning no other property, or the difference is reclaimed.

Annual tax. Owners pay property withholding tax (onroerende voorheffing / précompte immobilier). It is based not on market value but on cadastral income (kadastraal inkomen / revenu cadastral) - a notional annual rental value set by the state and indexed yearly. The tax is a regional base rate (3.97% of the indexed cadastral income in Flanders) plus provincial and municipal surcharges. The surcharges make up most of the bill, so similar homes in neighbouring municipalities can pay very different amounts.

Renting out. When an individual lets a flat to another individual as a home, tax is charged not on the actual rent but on the indexed cadastral income plus 40%. Letting to a company for its business is taxed on the actual rent minus expenses.

Selling. The main home is sold free of capital gains tax. Other houses and flats sold within 5 years of purchase are taxed at 16.5%; building land at 33% within 5 years and 16.5% in years six to eight. The new 10% tax does not apply to property.

Properties and ownership structures for investment are covered on the page about investment property in Belgium.

Inheritance and gifts

Inheritance tax (erfbelasting / droits de succession) is set by the region of the deceased's last residence. For children and spouses in Flanders the rates are 3% up to 50,000 euros, 9% up to 250,000 euros and 27% above; in Brussels and Wallonia the top rate for direct heirs is 30%. From 2026 a surviving spouse in Flanders receives up to 75,000 euros of cash and securities tax-free instead of 50,000 euros, while in Brussels the period during which an unregistered gift is taxed as inheritance has grown from 3 to 5 years. Wallonia will cut its rates from 1 January 2028.

Gifts of cash and securities to children in Flanders and Brussels can be registered with 3% gift tax.

Cars

Car registration tax (belasting op inverkeerstelling / taxe de mise en circulation) and the annual road tax (verkeersbelasting / taxe de circulation) are regional as well, based on engine power, CO2 emissions and the car's age.

What taxes non-residents pay and whether the treaty with Russia still applies

A non-resident pays Belgian tax only on Belgian income, but on the same scale of up to 50% and without the tax-free allowance if most of their earnings are not Belgian. The separate tax is called non-resident income tax (belasting van niet-inwoners / impôt des non-résidents), and its municipal surcharge is a flat 7%.

The tax-free allowance and family reliefs apply only if at least 75% of the year's professional income is earned in Belgium.

The new 10% capital gains tax is aimed primarily at residents. Payments to companies in other EU countries are often exempt from withholding under EU directives; for other countries the double tax treaty decides.

Does Belgium's tax treaty with Russia still apply

Formally the treaty exists, but since 2023 it has worked only halfway. Belgium and Russia signed their double tax convention in Moscow on 16 June 1995, and it was published in the Belgian official gazette on 27 October 2000. By Presidential Decree No. 585 of 8 August 2023, Russia unilaterally suspended key provisions of its treaties with 38 countries, and Belgium is on that list.

Suspended are the reduced rates and exemptions for dividends, interest and royalties, the rules on salaries, independent professions and more. Definitions, residence rules, elimination of double taxation and exchange of information stay in force. In practice Russia withholds tax on payments to Belgium under its own Tax Code without treaty relief: 15% on dividends and 20-30% on most other income.

Official sources show no Belgian termination or reciprocal suspension. A new convention of 2015 and its 2018 protocol have, per public records, not entered into force, so the 1995 text is the reference point.

For a Belgian resident with Russian dividends this means a double hit: Russia withholds 15%, and Belgium as a rule charges 30% on the rest without crediting the Russian tax. About 40% of the dividend goes in tax.

Ukraine and other countries

With Ukraine, a convention signed in Kyiv on 20 May 1996 applies. Ukrainians under temporary protection who live and work in Belgium pay tax under the ordinary Belgian rules: protection status brings no tax breaks. Belgium has a wide treaty network, including all EU countries, Kazakhstan, Israel and the United States.

When to file a tax return in Belgium and the penalties for filing late

The return for 2025 income had to be filed via the Tax-on-web portal by 15 July 2026, while a complex return is due by 16 October 2026. Filing late costs a fine of 50 to 1,250 euros plus a tax surcharge of up to 200%.

Returns are filed through Tax-on-web (inside the MyMinfin account of the Federal Public Service Finance) or on paper. Simple cases get a pre-filled simplified return (voorstel van vereenvoudigde aangifte / proposition de déclaration simplifiée) that needs no action if correct. A return counts as complex if it includes self-employed profits, company director's pay, a helping spouse's income or foreign professional income.

The self-employed and company directors whose income is not subject to withholding pay tax in advance instalments during the year. From 2026 income the self-employed no longer face a surcharge for skipping them and earn a discount for voluntary advance payments. For company directors the surcharge for insufficient advance payments remains.

Penalties. A late or incorrect return triggers an administrative fine: 50 euros for a first offence and more for each subsequent one, up to 1,250 euros. If income is undeclared or under-declared, a tax surcharge of 10% to 200% is added. Since 2025 no surcharge is charged for a first offence committed without intent: good faith is presumed if there were no similar offences in the previous 4 tax years. The rule was introduced by the programme law of 18 July 2025 and explained by the tax authority in circular 2025/C/49.

Without a return, the tax authority can assess the tax itself from its own data, which is harder to challenge later. Murblz specialists help sort out the first return after a move - with income before and after relocation and foreign accounts - before it is filed.

Who Belgium's tax system suits: takeaways for people relocating

Belgium is expensive for salaries and comparatively mild on capital. An employee on an average income hands more to the state than in any other OECD country, while an investor with a share portfolio pays, even after the 2026 reform, 10% on gains - less than in Germany or France.

Who Belgium suits. Well-paid professionals hired by a Belgian company under the inbound regime: 35% of the package tax-free changes the result. Investors with capital in securities: 10% on gains above 10,000 euros and no wealth tax apart from 0.15% on accounts of 1 million euros or more. Owners of small companies paying the director at least 50,000 euros.

Who it does not suit. Employees on average and high salaries without the special regime: the 45-50% rates start at about 30,000 and 51,000 euros of income. The self-employed on low incomes: the minimum contribution of 890.42 euros a quarter is due even with zero profit. Anyone receiving dividends from Russia: with the treaty suspended, the two countries' taxes take about 40%. And anyone planning to live in Belgium while staying tax resident elsewhere: with family and home in Belgium it almost never works.
