< Back to E-Invoicing Overview
Taiwan has fully implemented mandatory e-invoicing to modernize tax reporting and improve financial transparency. The system is designed to reduce tax fraud and streamline business transactions by requiring businesses to issue and validate invoices electronically.
E-invoicing in Taiwan is integrated with the national tax authority, ensuring that all invoices are properly recorded and reported. Businesses must use the government’s electronic invoice system for compliance.
Regulatory authority
The Ministry of Finance (MOF) oversees Taiwan’s e-invoicing system.
E-invoicing requirements
All VAT-registered businesses must issue electronic invoices. The system applies to B2B, B2C, and B2G transactions.
Accepted invoice formats
Invoices must be issued in XML format, following Taiwan’s Uniform Invoice System standards.
Transmission channels
Invoices must be submitted through the Electronic Invoice Platform (EIP) before being issued to recipients.
Digital signatures
