- Oman Tax Authority (OTA) will begin rolling out the national e-invoicing system in August 2026, starting with the 100 largest taxable entities.
- OTA released a draft e-invoicing Data Dictionary for public consultation and held workshops to clarify technical requirements.
- E-invoicing will apply to all transaction types (B2B, B2C, B2G), including standard, zero-VAT, and out-of-scope supplies, with significant compliance challenges expected for high-volume sectors.
- The Data Dictionary requires 53 mandatory data fields for standard e-invoices, with up to 66 additional fields in specific cases; printed invoices require 46 essential fields, with up to 50 more as needed.
- Real-time integration with approved service providers is required for B2B and B2G e-invoices; further guidance is pending for B2C transactions. Businesses should assess and update their ERP/billing systems to comply.
