Tax incentives in Wallonia


In order to stimulate the Belgian economy and increase the competitiveness of Belgian companies, the corporate tax rate has been reduced.

In 2020, the latest phase of corporate tax reform saw the nominal rate drop from 29% to 25%.


Ruling or advance ruling that creates legal certainty with regard to taxation

  • The investor describes the facts and enables the tax administration to determine, in advance and on a case-by-case basis, how the tax regulations will be applied
  • Forecasts all the tax implications of an investment project
  • Legally binding for all tax authorities


  • Valid for all taxes (corporation, VAT, personal income, etc.)
  • Ruling on a case-by-case basis
  • Tax certainty for the investor + binding for 5 years
  • Renewable
  • Open to existing and potential investors


  • Deduction for innovation income: income generated by a patent benefits from a favourable tax regime. A deduction of 85% is applicable to the relevant income, which brings the effective tax rate to 3.75%
  • Deduction for R&D investments
  • Exemption from the withholding tax on professional income for researchers
    • Exemption of 80% from the withholding tax on professional income on researchers' salaries
    • For researchers with a specific degree (doctor, engineer, masters, bachelors, etc.)

 This is a real measure to reduce the salary cost for employees assigned to R&D. This makes Belgium particularly competitive for R&D centres.


  • Replaces the notional interest deduction
  • Calculation basis = "incremental capital". Deduction limited to additional equity over a 5-year average
  • Deduction rate calculated annually (for example, for the 2019 tax year: 0.746% for large organisations and 1.246% for SMEs)


  • Exemption for dividends received: 95% deduction
  • Deductibility of interest paid to acquire shares
  • Exemption from capital gains on shares if the holding period is at least 12 months



Foreign company bosses and executives temporarily seconded to Belgium can benefit from a highly favourable tax regime.

  • Considered as non-resident in Belgium for tax purposes 
  • Tax exemption for working days abroad (notion of "travel exclusion")
  • Tax exemption on the expenditure allowance received from an employer to cover additional expenses related to the secondment in Belgium (€11.250/year for an operational entity and €29.750/year for HQ or R&D centre)

Employer benefits:

  • No taxes or social security contributions on the expatriation allowance
  • Deductible from corporation tax
