Document background
The Authorization Letter for TIN Number is a crucial document in Singapore's tax administration system, required when an individual or organization needs to delegate authority for handling Tax Identification Number matters. This document is particularly important for businesses establishing their tax presence, foreign entities requiring local representation, or individuals requiring assistance with tax matters. It must comply with IRAS requirements and Singapore's tax regulations, providing clear identification of all parties involved, specific scope of authorization, and validity period. The letter serves as official evidence of delegation and is commonly used in interactions with IRAS and other regulatory bodies.
