Decisio.be makes nothing up. Every figure, rate, condition or procedure presented on the site comes from official sources: federal administrations, regions, public bodies, regulated professions. Here is the complete list, classified by level and topic.
For every topic, we first consult the official source (FPS, region, public body). Media and secondary sources are only used to complement or clarify.
All pages display a last verification date. Tax topics and grants are reviewed monthly to track changes.
Decisio provides general information. For your specific situation, we systematically refer you to a professional: notary, accountant, legal advisor.
Sources used for everything that depends on the federal state: personal income tax, social security, self-employed status, healthcare.
Administrations, agencies and bodies specific to the Brussels-Capital Region.
Administrations, agencies and bodies specific to the Walloon Region.
Administrations, agencies and bodies specific to the Flemish Region.
Sources used for articles on health, insurance funds, BIM status and the Maximum Bill (MAB).
Sources from regulated professions (notaries) used for real estate articles, sale agreements and registration duties.
Specific pages used in energy articles, complementing the regional sources already listed above.
Specialized media and professional publications consulted occasionally to clarify or complement a primary source — never as a sole source.
The information published on this site is general syntheses based on the sources above. It does not constitute legal, tax or personalized financial advice. For any important decision (real estate purchase, choice of status, wealth transmission, financial plan), consult a qualified professional: notary, accountant, lawyer, independent financial advisor.
