Belgium Board Member and Director Fees Tax Guide

the Belgian tax treatment of directors' fees (bestuurdersvergoedingen / tantièmes / jetons de présence) — the fees paid to members of the board of directors (raad van bestuur / conseil d'administration) and the board of auditors (raad van toezicht / conseil de surveillance) of Belgian companies. The guide covers: the distinction between executive directors (the "dagelijks bestuurder" / "administrateur exécutif" — typically treated as an employee for social security purposes and subject to payroll tax) and non-executive directors (the "niet-uitvoerende bestuurder" / "administrateur non exécutif" — treated as self-employed for social security purposes, subject to the 30% withholding tax), the 30% withholding tax on directors' fees (the "roerende voorheffing" / "précompte mobilier" — the company withholds 30% on the gross directors' fees paid to non-executive directors; the withholding is the final tax for non-resident directors and a prepayment for resident directors), the social security treatment (non-executive directors are subject to the self-employed social security regime — the "sociale bijdragen zelfstandigen" / "cotisations sociales des indépendants" — at approximately 20.5% on the first €73,000 and 14.2% above — but only if the directors' fees exceed €15,267 per year; executive directors are subject to the employee social security regime — the RSZ/ONSS at approximately 13.07%), the deductible expense rules for the company (directors' fees are 100% deductible as professional expenses for the company — Article 49 WIB/92 — but the company must withhold the 30% roerende voorheffing at source), the personal income tax treatment for the director (the directors' fees are reported in the personal income tax return as "diverse inkomsten" / "revenus divers" — taxed at the progressive rates 25–50%), and the specific rules for the BV/SRL (besloten vennootschap / société à responsabilité limitée) — the managing director of a BV/SRL can choose between the employee regime and the self-employed regime for the management fee.

Directors' fees are a key component of Belgian corporate governance — the tax treatment differs significantly from regular employment income. All amounts in Euros (EUR). For related reading, see our Corporate Tax Guide →, DGA/Director's Tax Guide →, Company Forms Guide →, and Payroll Tax Guide →.

Executive vs Non-Executive Directors

Executive director (dagelijks bestuurder / administrateur exécutif): An executive director who holds a management role (the "dagelijks bestuur" / "gestion journalière" — daily management — the CEO, CFO, COO) is typically treated as an employee for Belgian social security purposes. The executive director: (a) receives a salary subject to bedrijfsvoorheffing / précompte professionnel (payroll withholding tax at progressive rates), (b) is subject to the RSZ/ONSS employee social security (13.07% employee contribution, approximately 27% employer contribution), (c) has the social security protection of an employee (health insurance, unemployment benefits, pension accrual). The executive director's total compensation (salary + benefits in kind — company car, insurance, phone) is fully subject to payroll tax and social security.
Non-executive director (niet-uitvoerende bestuurder / administrateur non exécutif): A non-executive director (a board member who does not hold a daily management role) is treated as self-employed (zelfstandige / indépendant) for social security purposes. The non-executive director: (a) receives directors' fees (bestuurdersvergoedingen / tantièmes / jetons de présence) subject to 30% withholding tax (roerende voorheffing / précompte mobilier), (b) is subject to the self-employed social security regime — approximately 20.5% on income up to €73,000 and 14.2% above — but only if the total directors' fees exceed €15,267 per year, (c) does NOT have employee-type protection (no unemployment benefits, no holiday pay). The distinction is critical — misclassification can result in significant social security reassessments.
The BV/SRL managing director option: For a managing director (zaakvoerder / gérant) of a BV (besloten vennootschap) / SRL (société à responsabilité limitée), Belgian law allows a choice: (a) the employee regime — the managing director receives a salary as an employee, subject to payroll tax and employee social security, (b) the self-employed regime — the managing director receives directors' fees (bestuurdersvergoedingen) subject to the 30% withholding tax and the self-employed social security regime. The choice depends on: the level of directors' fees, the social security coverage needed, and the tax optimisation strategy. The self-employed regime generally results in lower total social security costs (20.5% vs 13.07% + 27% employer).

Withholding Tax and Reporting

30% withholding tax (roerende voorheffing): The company must withhold 30% roerende voorheffing / précompte mobilier on the gross directors' fees paid to non-executive directors. The withholding is: (a) a final tax for non-resident directors (no further Belgian tax is due), (b) a prepayment for resident directors (the 30% is creditable against the final personal income tax liability — the "verrekenbare voorheffing" / "précompte imputable"). The company must pay the withheld amount to the FOD Financiën / SPF Finances within 15 days of the end of the month in which the fees are paid (the "aangifte roerende voorheffing" / "déclaration précompte mobilier" — the Form 273.1 for residents, Form 273.2 for non-residents).
Annual reporting (Form 281.20 / 281.25): The company must file an annual return of directors' fees paid: (a) Form 281.20 for resident directors — filed by 30 June of the following year, listing each director's name, address, national register number, and the gross fees paid, the withholding tax withheld, and the net payment, (b) Form 281.25 for non-resident directors — similar details but including the treaty relief claimed. The form is filed electronically via the Belcotax-on-web portal. The individualised data is pre-filled in the director's personal income tax return.

Personal Income Tax Treatment

Resident directors: The gross directors' fees are reported in the personal income tax return as "diverse inkomsten" / "revenus divers" (miscellaneous income — code 1150/2150 on the tax return). The fees are taxed at the progressive personal income tax rates (25–50%) plus the municipal surcharge (0–9%). The 30% roerende voorheffing withheld is creditable against the final tax — if the withholding exceeds the final tax, the excess is refunded. The director can deduct expenses if they choose actual expenses over the fixed allowance. The net directors' fees (after social security contributions) are the taxable base.
Non-resident directors: A non-resident director serving on a Belgian board is subject to Belgian tax on the directors' fees (the fees are Belgian-source income — the bestuurdersvergoedingen are sourced to Belgium because the mandate is exercised for a Belgian company). The 30% roerende voorheffing is the final tax for most non-resident directors. Under certain tax treaties, the taxing right may be allocated to the director's country of residence. The non-resident does not need to file a Belgian tax return if the 30% withholding is the final tax, unless the director also has other Belgian-source income.
