In 2020, the Zakat, Tax and Customs Authority (ZATCA) in Saudi Arabia announced the introduction of an e-invoicing mandate consisting of two phases. The first phase of Saudi e-invoicing requires all resident taxable persons in the Kingdom to generate and store invoices electronically and has been enforced since 4 December 2021. The second phase, which ZATCA will roll out as of 1 January 2023, brings additional requirements and will not be mandatory for all taxpayers to begin with. However, the ZATCA plans to gradually roll out and require all resident taxpayers to comply with phase-2 e-invoicing requirements.
