All Belgian enterprises must keep accounts; SMEs must keep a full set of accounts using the double-entry principle, with the option to submit annual accounts in abbreviated form, while large enterprises must submit annual accounts in full.
Accounting documents and all documents used to determine taxable income must generally be retained for seven years following the taxable period to which they correspond, with certain tax records and documents that form the basis for accounting required for ten years and immovable property-related documents potentially required for fifteen years.
Belgian companies must prepare annual accounts in accordance with Belgian GAAP and present them to shareholders; most must file annual accounts or consolidated accounts with the National Bank of Belgium, and foreign companies with Belgian branches must deposit specified documents in the official language of the branch.
Belgian branches of foreign companies are subject to the Belgian Accountancy Act and must keep separate bookkeeping, organise accounting books and records according to Belgian legal requirements and keep accounting information directly accessible in Belgium.
The purpose of Belgian bookkeeping is to provide a reliable basis for annual accounts and tax returns, support stakeholder decision‑making and ensure compliance with Belgian accounting and tax law.
Properly maintained Belgian accounts and statutory books, complete annual accounts filed as required and accounting and tax documents retained for seven, ten or fifteen years depending on their nature.
