Belgium Tax Regime

A high-tax jurisdiction in the heart of the EU

Belgium is a federal state whose tax system is administered principally at federal level by the Federal Public Service Finance (FPS Finance / SPF Finances / FOD Financiën), with significant powers devolved to the three Regions (Flanders, Wallonia and Brussels-Capital) over registration duties, inheritance and gift taxes, and certain property levies. Corporate and personal income taxes, VAT, and most withholding taxes remain federal. As an EU and eurozone member and an OECD founder, Belgium implements EU directives (Parent-Subsidiary, Interest & Royalties, ATAD I and II, DAC, the Pillar Two Directive) and follows OECD standards on transfer pricing and information exchange.

Belgium has historically combined a high headline corporate rate and very high effective labour taxation with a comparatively light taxation of individual investment income and, until recently, no general capital gains tax on private financial assets. That balance shifted materially under the De Wever I federal government formed in 2025 (the so-called 'Arizona' coalition), whose 2025-2029 agreement introduced a new tax on capital gains on financial assets from 1 January 2026, raised several withholding rates, tightened participation-exemption conditions, and reformed procedural rules. This handbook reflects the position as enacted for income year 2025 / assessment year 2026 and measures taking effect in 2026, verified against FPS Finance guidance and the underlying legislation as of July 2026.

Residence drives the scope of taxation. Companies with their registered office, principal establishment, or place of effective management in Belgium are resident and taxed on worldwide profits; non-resident companies are taxed only on Belgian-source income, typically through a permanent establishment. Individuals whose domicile or seat of wealth is in Belgium are resident and taxed on worldwide income, with double-tax relief under Belgium's extensive treaty network of roughly 100 conventions.

Rates and the SME reduced rate

The standard corporate income tax (CIT) rate is 25%, applied to worldwide accounting profit as adjusted for tax purposes. Qualifying small companies (meeting the size criteria of Article 1:24 of the Code of Companies and Associations) benefit from a reduced rate of 20% on the first EUR 100,000 of taxable profit, with the balance taxed at 25%. Access to the reduced rate is conditioned, among other requirements, on the company paying at least one director a minimum gross annual remuneration; that minimum rises from EUR 45,000 to EUR 50,000 as from assessment year 2026 (financial years closing on or after 31 December 2025). Companies failing the remuneration test lose the reduced rate but no longer face the separate special assessment that previously penalised under-payment in most cases.

A CIT surcharge is levied on the final tax due where a company has not made sufficient advance payments during the year. For assessment year 2026 the surcharge is 6.75%. It is effectively neutralised by making adequate quarterly advance payments, which generate tax credits of (for TY2026) 9%, 7.5%, 6% or 4.5% of the payment depending on the quarter in which it is made — a strong incentive to pay early.

Participation exemption (DRD) and capital gains on shares

The dividends-received deduction (DRD / RDT-DBI), transposing the EU Parent-Subsidiary Directive, historically exempted 100% of qualifying dividends by adding them to the base and then deducting them. Under the 2025 reform the mechanism is converted from a deduction into a direct exemption for financial years starting on or after 1 January 2025, and the qualifying conditions are tightened: alongside the long-standing one-year holding and taxation ('subject-to-tax') tests, the minimum participation to qualify remains a 10% shareholding or an acquisition value of at least EUR 2.5 million, but for participations held by large companies in other large companies the value threshold is raised to EUR 4 million (the 10% test being unaffected). Capital gains on shares are exempt on essentially the same conditions.

Innovation income deduction and notional interest

The innovation income deduction allows an 85% deduction of qualifying net income from patents, supplementary protection certificates, plant-breeders' rights, orphan-drug designations and copyrighted software, yielding an effective rate as low as 3.75% on eligible income; it follows the OECD nexus approach and unused deduction carries forward. The notional interest deduction (deduction for risk capital) — once a signature Belgian incentive giving a notional return on adjusted equity — has been effectively neutralised: its rate has been at or near zero for several years and the government has confirmed its abolition, so it no longer offers meaningful relief. Losses may be carried forward indefinitely, subject to the 'basket' rule limiting the offset of the annual profit above EUR 1 million to 70% (the government having signalled an increase of this cap toward 100% in later reform phases).

Progressive federal brackets

Resident individuals are taxed on worldwide income under a progressive federal schedule. For income year 2025 (assessment year 2026) the brackets are 25% up to EUR 16,320; 40% from EUR 16,320 to EUR 28,800; 45% from EUR 28,800 to EUR 49,840; and 50% above EUR 49,840. A tax-free allowance of EUR 10,910 applies (increased for dependent children and other dependants), granted as a reduction rather than an exempt slice. Professional income, replacement income, and most other income aggregate into this progressive base, with employees' compulsory social-security contributions and professional expenses (actual or a lump-sum deduction) reducing the taxable amount.

Communal surcharge and the true top rate

On top of the federal tax, municipalities levy an additional communal tax (additionnels communaux / aanvullende gemeentebelasting) calculated as a percentage of the federal tax due, generally between 0% and about 9%, averaging roughly 7%. Because the surcharge multiplies the tax rather than the income, the effective marginal rate for a resident in a typical municipality exceeds 53%. Non-residents pay a fixed surcharge in lieu of the communal tax. These combined rates place Belgium among the highest-taxing OECD countries for labour income.

Investment income and the new capital gains tax

Dividends and interest received by individuals are normally taxed at a flat 30% movable withholding tax, generally discharging further liability. The headline reform for individuals is the new tax on capital gains on financial assets, applicable to gains realised from 1 January 2026 (gains accrued up to 31 December 2025 remain untaxed, with the 31 December 2025 value serving as the default acquisition base). The residual category (Category C — most shares, bonds, funds, ETFs, derivatives and crypto-assets) is taxed at a flat 10%, with an annual exemption of EUR 10,000 per taxpayer (indexed and with limited carry-forward). Holders of a 'substantial participation' (Category B — at least 20% of a company) benefit from a EUR 1 million exemption and then graduated rates from 1.25% up to 10%; certain internal capital gains on transfers to a controlled company (Category A) are taxed at 33%, and transfers of substantial participations to entities outside the EEA can trigger a 16.5% flat rate on the excess above EUR 1 million.

Domestic movable withholding tax

The standard rate of movable withholding tax (précompte mobilier / roerende voorheffing) on dividends, interest and royalties paid to residents and non-residents is 30% before treaty relief. This is a gross domestic statutory rate; a broad set of domestic reductions and exemptions apply before any tax-treaty benefit is even considered. Dividends to qualifying EU/treaty parent companies are exempt under the Parent-Subsidiary Directive (implemented domestically), and interest and royalties between associated EU companies are exempt under the Interest & Royalties Directive, subject to holding and anti-abuse conditions.

VVPR-bis, liquidation reserve and treaty network

Two domestic regimes reduce the effective dividend burden for SMEs. The VVPR-bis regime grants a reduced dividend withholding rate on shares issued for cash from incorporation of qualifying small companies; that reduced rate rises from 15% to 18% as of 1 July 2026 (distributions on or before 30 June 2026 keeping 15%), and the parallel liquidation-reserve rate on distributions after the three-year waiting period rises from 6.5% to 9.8% for reserves linked to assessment year 2026 and later. These changes harmonise the two schemes and add anti-abuse safeguards. Belgium's roughly 100 double-tax treaties, most based on the OECD Model and increasingly modified by the Multilateral Instrument (MLI), typically cut residual dividend withholding to 0%/5%/15% and interest and royalties to 0%/10% depending on the counterparty and holding.

Transfer pricing

Belgium applies the arm's-length principle in line with the OECD Transfer Pricing Guidelines. Groups meeting the thresholds must maintain a master file, local file and country-by-country report (CbCR); the local file and master-file forms are filed with the tax authority, and CbCR applies to multinationals with consolidated revenue of at least EUR 750 million. In March 2026 the authorities issued Circular 2026/C/45 (an addendum to Circular 2020/C/35) adopting the OECD's simplified and streamlined approach ('Amount B') for routine marketing and distribution activities, with retroactive effect for transactions from 1 January 2025.

CFC, ATAD and general anti-abuse

Belgium implemented the EU Anti-Tax-Avoidance Directive (ATAD I and II), including interest-limitation rules (30% of EBITDA / EUR 3 million de minimis), exit taxation, hybrid-mismatch rules and controlled-foreign-company (CFC) rules. The CFC regime attributes undistributed passive income of low-taxed foreign subsidiaries and PEs to the Belgian parent; following a 2026 Court of Justice of the EU ruling that Belgium's initial CFC transposition was incomplete (failure to fully implement Article 8(7) ATAD), the regime is being aligned. A statutory general anti-abuse rule (GAAR) and numerous specific anti-abuse provisions supplement these measures.

Pillar Two

Belgium has implemented the OECD/G20 Pillar Two global minimum tax through the EU Minimum Tax Directive, via the Law of 19 December 2023 (as amended by the Law of 12 May 2024 and subsequent technical amendments aligning with OECD Administrative Guidance). In-scope groups (consolidated revenue of at least EUR 750 million) face a 15% minimum effective tax rate enforced through a Qualified Domestic Minimum Top-up Tax (QDMTT), an Income Inclusion Rule (IIR) and an Undertaxed Profits Rule (UTPR). Belgium operates a Pillar Two registration and prepayment system; filing deadlines for QDMTT and IIR returns otherwise falling before 30 September 2026 have been generally deferred to 30 September 2026.

VAT

The standard VAT rate is 21%, applying to most goods and services. A reduced 12% rate applies to certain supplies including restaurant and catering services (excluding beverages), and a 6% rate covers basic necessities such as most foodstuffs, water, pharmaceuticals, books and certain housing works. From 1 March 2026 several supplies moved from 6% to 12% (including hotel and camping accommodation, sport and entertainment admissions, and take-away meals and beverages). VAT registration, periodic returns and, increasingly, e-invoicing obligations follow the EU framework, with domestic B2B structured e-invoicing being phased in.

Registration duties and regional wealth taxes

Transfers of Belgian real estate attract regional registration duty: broadly 12.5% in Brussels and Wallonia and 12% in Flanders for second homes and investment property, with sharply reduced rates for a purchaser's sole owner-occupied dwelling — around 2% in Flanders and 3% in Wallonia, subject to conditions. Inheritance and gift taxes are also regional and progressive, with rates depending on the relationship and the Region; in Flanders the top rate for direct-line heirs and partners reaches 27% (over EUR 250,000), while gifts of movables can be made at reduced flat rates (e.g. 3% in direct line / between partners, 7% to others in Flanders).

Annual tax on securities accounts and other levies

An annual tax on securities accounts applies at 0.15% to accounts whose average value exceeds EUR 1 million (the 2025 reform retained the 0.15% rate rather than raising it, while reinforcing anti-abuse rules). Other levies include local property tax (précompte immobilier / onroerende voorheffing) based on cadastral income, excise duties, insurance-premium tax, and stock-exchange tax on secondary-market securities transactions.

Assessment and investigation periods

Income tax operates on an assessment-year basis: for a company or individual whose financial year matches the calendar year, income year 2025 corresponds to assessment year 2026. Following the 2025 procedural reform, the layered 3/4/6/10-year framework introduced from AY2023 is largely replaced by a return toward a simpler regime: a three-year ordinary investigation and assessment period for timely-filed returns, a four-year period for late or non-filed and 'complex' returns, and a seven-year period in cases of fraud.

Objections, appeals and rulings

A taxpayer disputing an assessment files an administrative objection with the regional tax director, generally within a statutory period from the assessment notice; an unfavourable decision (or the absence of one) can be challenged before the courts of first instance, then the courts of appeal and ultimately the Court of Cassation. Belgium offers advance tax rulings through the Office for Advance Tax Rulings (Service des Décisions Anticipées), giving binding certainty on the tax treatment of proposed transactions, and mutual-agreement and arbitration procedures are available for cross-border disputes under treaties and the EU Tax Dispute Resolution Directive.

Key deadlines

Corporate income tax returns are filed electronically (Biztax); for companies with a financial year ending between 31 December 2025 and end-February 2026, the return is generally due by 30 September 2026 (broadly, at least until the seventh month after year-end, with an outer limit). Personal income tax returns are filed via Tax-on-Web, with staggered deadlines around mid-2026 (typically mid-July for paper/online individual filings, later for returns lodged through an authorised agent). Advance payments for both CIT and self-employed PIT are made quarterly to avoid the surcharge.

Choosing a vehicle and financing

The most common corporate vehicle is the private limited company (SRL / BV), with the public limited company (SA / NV) used for larger ventures; branches of foreign companies are taxed as non-resident permanent establishments on Belgian-source profits. There is no minimum capital requirement for the SRL/BV, though 'adequate' initial equity is required. Belgium remains attractive for holding and financing activities thanks to the participation exemption, the absence (under domestic law) of withholding on many qualifying intra-EU flows, and an extensive treaty network, notwithstanding the erosion of the notional interest deduction.

Workforce, incentives and reform trajectory

Employer social-security charges are significant, which — combined with high personal rates — makes labour costs a central planning issue; targeted reductions, the expat inbound-taxpayer regime (with 2026 enhancements), the innovation income deduction, R&D wage-withholding-tax incentives and regional grants partly offset this. Businesses should monitor the multi-phase Arizona reform: the capital gains tax, DRD-to-exemption conversion, higher VVPR-bis and liquidation-reserve rates, and VAT rate reclassifications are already in force in 2026, while further changes to loss relief, group taxation and procedural rules are expected. Professional advice on the interaction of federal and regional taxes is essential.
