The Tax Residency Certificate (TRC) is an official document issued by the competent tax authority of a country to confirm that a company is a tax resident in that jurisdiction. It is a key instrument for claiming benefits under Double Taxation Avoidance Agreements (DTAAs) and is widely required for international tax filings, cross-border business operations, regulatory compliance, and avoidance of dual taxation. The TRC is commonly referred to as a Certificate of Fiscal Residence, Certificate of Tax Residence, or Tax Domicile Certificate in various jurisdictions.
