- Taiwan e-invoicing (eGUI) is mandatory for most B2B and B2C transactions and requires invoices to be in MIG 4.0 XML format, digitally signed, AES-encrypted, and transmitted to the Ministry of Finance’s platform.
- Non-compliance can result in fines, audits, and business disruptions.
- Compliance requires mapping invoice flows, connecting to the MoF platform (directly or via a certified provider), and implementing monitoring and archiving.
- Outsourcing to a managed e-invoicing provider can reduce operational risks and maintenance.
- Key deadlines: e-invoicing mandatory since Jan 2021, MIG 4.0 standard from Jan 2024, and full transition by Dec 2025.
