In June 2026, the Oman Tax Authority confirmed to Stackcue that the minimum capital requirement to become a licensed Fawtara e-invoicing service provider has been cut from 60,000 OMR to 6,000 OMR — a 90% reduction (Oman Tax Authority, direct communication, June 2026). That's not a footnote. It's a signal that Oman is actively expanding its Fawtara ecosystem with Phase 1 mandatory compliance just weeks away for the country's 100 largest taxpayers.
Fawtara — Arabic for "invoice" — is Oman's structured e-invoicing programme, built on the Peppol five-corner model and UBL 2.1 XML standard. The Oman Tax Authority (OTA) was officially approved as a Peppol Authority by OpenPeppol on 7 January 2026 (VATupdate, "Oman Approves Peppol Framework, Sets 2026 Timeline," January 2026), locking in the technical framework for a rollout that will eventually cover every VAT-registered business in Oman.
This guide covers the legal basis, the three-phase rollout, the technical requirements, how to choose a licensed service provider, and how Fawtara compares to the UAE and Saudi Arabia. If your business issues B2B or B2G invoices in Oman, this is what you need to know now.
Key Takeaways- Fawtara Phase 1 launches August 2026, covering approximately 100 of Oman's largest taxpayers (B2B and B2G only).- The April 2026 PINT Oman draft raised mandatory fields to 73 — UBL 2.1 XML over a Peppol five-corner network (KPMG, "Draft PINT Oman Specifications for E-Invoicing Published," April 2026).- In June 2026, the OTA confirmed the ASP capital requirement dropped from 60,000 OMR to 6,000 OMR — expanding the licensed provider pool.- Phase 3 reaches all VAT-registered SMEs in August 2027; full programme completion is August 2028.

What Is Oman's Fawtara E-Invoicing Programme?
Fawtara is Oman's mandatory structured e-invoicing programme, administered by the Oman Tax Authority. The legal basis is Decision No. 456/2022, which amends Oman's VAT Executive Regulations to introduce the e-invoicing framework (Deloitte, "Oman E-Invoicing — Fawtara Programme Overview", October 2025). It requires businesses to issue digital invoices in a structured XML format through a Peppol-connected network — not PDFs, not paper.
"Fawtara" translates from Arabic as "invoice." The name signals intent: this replaces how commercial invoices are created and transmitted in Oman, not just how they're stored.
The four core components of the Fawtara system:
- Peppol network: Invoices travel through a five-corner model — supplier to supplier ASP to Peppol network to buyer ASP to OTA
- UBL 2.1 XML: The technical format required for all Fawtara invoices
- 73 mandatory data fields: Including TIN, VAT registration number, line-item detail, tax amounts per line, and supply classification codes
- Accredited Service Providers (ASPs): OTA-licensed intermediaries that connect your business to the Peppol network
What Fawtara is NOT: it's not a PDF-by-email upgrade, not a reporting layer on top of existing invoicing, and not optional for in-scope businesses once their phase deadline passes.

Which Businesses Does Fawtara Apply To?
In October 2025, Deloitte confirmed that Fawtara applies to B2B and B2G transactions — business-to-consumer invoices are currently excluded (Deloitte, "Oman E-Invoicing — Fawtara Programme Overview," October 2025). Scope is tied to transaction type, not just VAT registration status: any business issuing B2B or B2G invoices in Oman will fall within the programme as the phases expand.
Phase 1 targets approximately 100 of Oman's largest taxpayers — identified by the OTA, not self-declared. Phases 2 and 3 progressively extend to all remaining large businesses and then to all VAT-registered SMEs above the mandatory OMR 38,500 threshold.
Who needs to act, and when:
| Business type | Phase | Deadline |
|---|---|---|
| ~100 largest taxpayers | Phase 1 | August 2026 |
| All other large taxpayers | Phase 2 | February 2027 |
| All VAT-registered SMEs | Phase 3 | August 2027 |
The Phase 1 list of approximately 100 businesses isn't public. If you're a large taxpayer by turnover and haven't been contacted by the OTA, don't assume you're out of scope — contact the OTA directly via taxoman.gov.om before July 2026 to confirm your status. Waiting to be notified is a risk.
B2C-only businesses and non-VAT-registered businesses are currently excluded from Fawtara scope. That may change in future phases as the programme matures.

What Are the Fawtara Implementation Phases and Deadlines?
As of May 2025, KPMG confirmed four implementation milestones for Fawtara, noting the phase dates are published but subject to OTA confirmation as standalone enabling legislation was still being finalised (KPMG, "Oman Expected to Implement E-Invoicing from Q3 2026", May 2025).
The two-year rollout mirrors the phased approach taken by UAE (PINT AE, 2027) and Saudi Arabia (FATOORAH, 2021–2022). Starting with the 100 largest taxpayers limits initial risk while building ASP infrastructure and allowing the OTA to refine the technical requirements before wider rollout.
Phase 3 is the critical deadline for most businesses. August 2027 catches every VAT-registered SME above the OMR 38,500 mandatory registration threshold — that's the majority of Oman's registered tax base.

What Technical Standard Does Fawtara Use?
In January 2026, the Oman Tax Authority was formally approved as a Peppol Authority by OpenPeppol (VATupdate, "Oman Approves Peppol Framework, Sets 2026 Timeline," January 2026). This approval locked in the technical architecture: all Fawtara invoices must be transmitted via the Peppol five-corner model in UBL 2.1 XML format.
The Peppol five-corner model:
The draft data dictionary published in November 2025 initially specified 53 mandatory fields (KPMG, "OTA Releases Draft Data Dictionary for E-Invoicing," November 2025). The April 2026 draft PINT Oman specifications raised this to 73 mandatory fields — 28 new fields were added, three removed, and five reclassified as optional (KPMG, "Draft PINT Oman Specifications for E-Invoicing Published", April 2026). These include supplier and buyer TINs, VAT registration numbers, invoice date, currency, line-item descriptions, tax amounts per line, and supply classification codes.
What this means for your systems: if your ERP generates PDF invoices today, you need either a system upgrade to output UBL 2.1 natively or an ASP that handles the conversion from your existing format. Most ASPs offer a middleware layer for this. The UBL 2.1 requirement is non-negotiable — there's no alternative format.

How Do You Choose a Licensed Fawtara Service Provider?
In June 2026, the Oman Tax Authority confirmed directly to Stackcue that the minimum paid-up capital requirement for Fawtara ASP accreditation has been reduced from 60,000 OMR to 6,000 OMR — a 90% reduction (Oman Tax Authority, direct communication, June 2026). Stackcue holds the official written communication. This change hasn't been published elsewhere.
Why does this matter for businesses selecting a provider? The lower threshold will attract more applicants into the accreditation process. The licensed ASP pool will grow over the next 12–18 months, bringing more pricing competition and more sector-specific options. If you're evaluating providers now, don't lock into a long-term contract without a reassessment clause.
What to evaluate when selecting a Fawtara ASP:
1. OTA accreditation status
Only OTA-accredited ASPs can legally connect your business to the Fawtara network. Verify current accreditation on taxoman.gov.om before signing anything.
2. ERP and system compatibility
Does the ASP support your ERP — SAP, Oracle, Microsoft Dynamics, or a local system? Integration complexity and timelines vary significantly. Ask for a specific implementation timeline and reference clients on your ERP.
3. UBL 2.1 conversion capability
If your system doesn't output UBL 2.1 natively, confirm the ASP can convert from your current invoice format. Not all providers handle all source formats equally well.
4. GCC coverage
If you operate in the UAE or Saudi Arabia as well, check whether your ASP is also licensed for those markets. Cross-border GCC coverage under one provider simplifies operations significantly.

How Does Fawtara Compare to UAE and Saudi E-Invoicing?
Oman sits between two active GCC e-invoicing programmes. In January 2026, VATupdate confirmed that all three major GCC markets — Saudi Arabia, UAE, and Oman — now operate Peppol-aligned e-invoicing frameworks, though with meaningful technical and structural differences (VATupdate, "Oman Approves Peppol Framework, Sets 2026 Timeline for National E-Invoicing System Fawtara", January 2026).
| Dimension | Oman (Fawtara) | UAE (PINT AE) | Saudi (FATOORAH) |
|---|---|---|---|
| Invoice format | UBL 2.1 XML | PINT AE (Peppol) | UBL 2.1 + ZATCA extensions |
| Network model | Peppol five-corner | Peppol five-corner | Clearance model |
| Phase 1 scope | ~100 largest taxpayers | ≥ AED 50M revenue | All VAT-registered (complete) |
| Phase 1 go-live | August 2026 | January 2027 | December 2021 |
| B2C scope | Excluded (current) | Excluded | Included |
| Tax authority copy | Yes (concurrent) | Yes (concurrent) | Pre-clearance required |
The key structural difference is Saudi Arabia's clearance model: invoices must be validated by ZATCA before delivery to the buyer. Oman and UAE both use the Peppol five-corner model where the tax authority receives a concurrent copy but doesn't block transmission. This makes implementation faster and less disruptive to existing accounts payable workflows.
Oman's Phase 1 go-live (August 2026) actually precedes UAE's Phase 1 go-live (January 2027). Finance teams managing cross-border GCC operations will face Oman compliance before UAE compliance — the opposite of what most regional finance teams are planning for. If your ASP selection has been driven by UAE PINT AE readiness, confirm they're also Oman-accredited.

What Steps Should Your Business Take Before August 2026?
Phase 1 go-live is August 2026 — approximately six weeks from today. For Phase 1 businesses, there's no runway left; action is immediate. For Phase 2 and Phase 3 businesses, the preparation you do now determines how smoothly your deadline goes.
Immediate — this week:
- Confirm your phase status — Contact the OTA via taxoman.gov.om or your tax adviser to verify whether you're in Phase 1 scope. Don't assume you're out of scope because you haven't been notified.
- Assess your ERP output — Can it generate UBL 2.1 XML? If not, document the gap and timeline to fix it.
- Shortlist accredited ASPs — Check the OTA's accredited provider list. Note that new providers will qualify over the next 12–18 months.
Short-term — next 30–60 days:
- Select and contract an ASP — Phase 1 businesses need to move immediately. Phase 2 and 3 businesses should start conversations now before ASP demand peaks closer to their deadlines.
- Begin integration and testing — ASP connections require IT time and data mapping. Build in at least 4–6 weeks of buffer for issues.
Ongoing:
- Train your finance team — Fawtara changes how invoices are issued and received, not just the format. Accounts payable and receivable workflows both change.
- Align with VAT return filing — E-invoice data must reconcile with VAT returns filed via the OTA portal. For the VAT return process, see the Oman VAT return filing guide.
Every GCC e-invoicing implementation we've seen takes longer than finance teams expect. ERP data mapping, ASP onboarding, and testing with counterparties all create delays. Start earlier than you think you need to.
