A Tax Affidavit is a critical legal document used in Belgian tax administration and compliance. It is required when taxpayers need to make formal declarations about their tax affairs, whether for personal income tax, corporate tax, inheritance tax, or other tax-related matters. The document must be prepared in accordance with Belgian federal and regional tax laws, and typically includes detailed information about the declarant's financial situation, specific tax circumstances, and supporting calculations. A Tax Affidavit may be required during tax audits, in response to tax authority inquiries, for tax relief applications, or in connection with international tax matters. The document carries legal weight and false declarations can result in significant penalties under Belgian law.
