What is Taiwan's GUI (Government Uniform Invoice) e-invoice system?
Effective: 2010-01-01 · Authority: MOF (Ministry of Finance Taiwan)
Taiwan's GUI (Uniform Invoice) system requires all businesses to issue government-formatted invoices for taxable sales. Electronic GUIs (e-GUIs) have been progressively mandated since 2010 for B2B transactions and are expanding to B2C. The MOF (Ministry of Finance) operates the central e-GUI platform for invoice validation and consumer prize lottery integration.
How does Taiwan's GUI lottery system work?
Taiwan's GUI includes a unique feature: the last 8 digits of each B2C invoice number participate in a bi-monthly government lottery with cash prizes. This creates strong consumer incentive to request invoices and accept only genuine GUIs. The lottery dramatically reduces B2C tax evasion by making consumers active tax compliance enforcers.
