Document background

The Self Assessment Form is a mandatory tax reporting document used in Belgium for declaring income and calculating tax liability to the Belgian tax authorities. It is required to be submitted annually by residents and specific categories of non-residents who have taxable income in Belgium. The form requires detailed information about various income sources, including employment, professional activities, investments, and real estate, as well as applicable deductions and exemptions.
