Document background
The Authorization Letter for TIN ID is a critical document in Singapore's tax administration system, enabling taxpayers to delegate authority for handling their Tax Identification Number matters. This document is particularly necessary when individuals or businesses need representatives to manage their tax affairs with IRAS. The letter must include specific details about the authorizer and authorized party, clearly outline the scope of authority, and comply with Singapore's tax regulations and PDPA requirements. It serves as official evidence of delegation and is commonly used for both personal and business tax matters.
