The Kingdom of Saudi Arabia has mandated e-invoicing Phase One (Generation Phase) since 4 December 2021, and Phase Two (Integration Phase) will come into effect on 1 January 2023. When the integration phase kicks off, taxpayers will be required to exchange their invoice data with the tax authority - ZATCA. ZATCA has announced that it will offer to subsidize the purchase of e-invoicing software. In order to submit a request, taxpayers must provide certain detailed information and the invoice they received from the e-invoicing service provider. The "E-invoicing Subsidy Request" form can be accessed on the taxpayer portal.
