Thiqah implements the changes your accounting and ERP systems need to meet Oman’s e-invoicing requirements, from scoping to go-live and team training.
Fawtara is Oman’s national e-invoicing system, run by the Oman Tax Authority. Under Decision No. 189/2026, which amends the VAT Executive Regulations, tax invoices must be issued in an approved, secured electronic format and sent through a Tax Authority-accredited service provider. Paper invoices, ordinary PDFs and invoice images sent by email no longer count as tax invoices once the duty applies to you.
Businesses with annual supplies above OMR 5 million.
Businesses with annual supplies of OMR 5 million or less.
Invoices pass through a service provider accredited by the Tax Authority. You choose the provider and can change it later.
Dates follow Decision No. 189/2026 (Official Gazette, 9 August 2026). Rules and dates can change, so confirm the current position with the Oman Tax Authority. This page is general information, not legal or tax advice. Last reviewed 28 October 2026.
Four steps that take your systems from today’s invoicing to compliant e-invoicing.
We review how you invoice today and what must change before your date.
We configure your system to issue invoices in the approved format and connect to your chosen accredited provider.
We test before you rely on it, then stay through the first live period.
So finance and sales teams know what changes in their daily work.
