Taiwan GUI VAT e-invoice

Taiwan implemented post-issuance government e-invoicing via its Government Uniform Invoice (GUI) regime. This allocates batch sequence invoice numbers to taxpayers every couple of months. The system was launched in 2006 as paper-based pre-printed invoices, and switched to electronic in 2017. This requirement was mandated for non-residents from the start of 2020, with VAT registered foreign businesses having to engage with a local, certified invoicing partner.

  1. Appointing a local certified invoicing agent; or
  2. Using the free transmission software provided by the Ministry of Finance to sending invoice data from ERPs.
