Already in scope
Notified directly by the Tax Authority
The requirement applies to you now. Invoices issued outside the system are not compliant, and every day without a working connection carries risk.
Compliance Guide
Oman e-invoicing and VAT, explained.
A practical, plain-language reference for owners and finance managers preparing for the Oman Tax Authority's e-invoicing mandate. Written to be read once and returned to.
Last updated August 2026 · General guidance, not tax or legal advice — always confirm with the Oman Tax Authority.
Where you stand
The mandate has started. Your business will be included.
Fawtara is being applied in stages by taxpayer size. The Tax Authority confirms which businesses are included and when. What does not change from one group to the next is the preparation — and that is the part you control.
Not yet notified
VAT-registered, awaiting your group's date
You are within the scope of the rollout and your date will be confirmed by the Authority. Preparation takes months and cannot be compressed into the weeks before a deadline, when every other business is doing the same thing.
Not registered for VAT
Below the registration threshold
Fawtara currently follows VAT registration. If you cross the threshold, you come into scope — worth knowing before it happens rather than after.
The cost of waiting
Delays, rejected invoices, penalties
A business that starts late connects under pressure. Data problems surface after invoices are rejected rather than before, filings fall behind, and the penalties attached to invoicing and record-keeping obligations become a real risk rather than a theoretical one. None of that happens to a business that prepared.
The Fawtara platform is operating and the infrastructure is in place. The rollout is moving outward from the first group.
Your obligation and its date are set by the Oman Tax Authority — confirm both with them directly. Preparation, however, does not depend on the date, and it is the part that takes time.
The basics
What Fawtara actually means for your invoices.
Fawtara is the Oman Tax Authority's electronic invoicing system. It changes how an invoice is created, sent and recorded — not what you charge or who you sell to.
An ordinary PDF invoice
- Unstructured — software can't read the fields
- No validation before it reaches your customer
- Emailed directly, no network record
- No tax data reported to the Authority
- No audit trail
An Oman e-invoice
- Structured data in PINT OM (UBL 2.1 XML)
- Validated against mandatory fields before submission
- Exchanged over the Peppol network
- Invoice tax data reported to the Authority
- Full audit trail, archived in original format
PDF/A-3 — a readable PDF with the structured invoice data embedded inside it — carries the structured data a flat PDF lacks. A flat PDF does not meet the requirement, however you send it.
You can still send your customer a readable copy for convenience. The structured file is the one that counts.
The spec
What makes an invoice compliant.
Required fields (non-exhaustive)
- Supplier name, CR number, VAT registration and TIN
- Buyer name and TIN (for B2B and B2G)
- Invoice number and issue date/time
- Itemised line-level detail — quantity, unit price, description
- VAT category, rate and amount per line
- Net, VAT and gross totals
- QR code on the readable copy where required
- Digital signature or cryptographic stamp where required
Formats and standards
- PINT OM — Oman's Peppol International invoice specification
- UBL 2.1 structured XML
- PDF/A-3 — readable PDF with structured data embedded
- Long-term archival in original format with audit trail
VAT
The 5% rate, and what falls under it.
Standard
5%
Most goods and services supplied in Oman, including imports. Applied at each stage with credit for input VAT.
Zero-rated
0%
Exports of goods and services, international transport, certain food items, medicines and medical equipment, and investment-grade precious metals.
Exempt
Most financial services, residential real estate, bare land, and healthcare and education in defined cases. No VAT charged, no input recovery.
Both lists above are indicative, not exhaustive. Oman's zero-rated and exempt categories are set out in the VAT law and its executive regulations.
Where this matters for Fawtara: every product and service in your catalogue has to be mapped to the right category before your invoices will validate. Mapping the catalogue is one of the jobs we do in step two.
The network
How an invoice actually travels.
Peppol is a global network for exchanging structured business documents. PINT is its international invoice specification, which participating countries adapt locally — Oman's version is PINT OM.
Your system
You raise the invoice in the accounting software you already use — Xero, QuickBooks, Odoo, Tally, or something local.
Your provider
The invoice data is validated, mapped to PINT OM, signed, and put onto the network. This is the part Dhara runs for you.
Your customer's provider
Their provider receives the structured invoice and delivers it into their system.
Your customer
It arrives as structured data they can process — not a PDF someone rekeys.
The practical consequence: you don't email invoices any more. You raise them the same way, and they leave through a network instead of an inbox.
In practice
What actually changes inside your business.
Your invoice data has to be clean.
Customer tax numbers, item descriptions, tax codes, totals — fields you may have filled loosely will now be validated. Incomplete data means rejected invoices.
Your accounting software has to connect.
Xero, QuickBooks, Zoho Books, Odoo or something local — it needs a path to the network. Most businesses don't need to replace their system.
Someone has to watch for rejections.
A failed invoice isn't accepted onto the network and must be corrected and resent — same day, not at month end.
Your records are kept differently.
Invoices are archived as structured files with an audit trail, and that becomes the record the Authority can ask for.
Your VAT position gets more visible.
When invoice data reaches the Authority in near real time, your books and your filings have to agree more closely — which is why the bookkeeping behind them has to be current.
That last point is why we don't sell e-invoicing on its own. If the books behind the invoices aren't in order, connecting to the network only makes the problem visible faster.
Obligations
What the law requires.
Oman's VAT law sets out obligations around registration, invoicing, accuracy and record-keeping, with penalties attached to each. We state them here because you should know them — not as a reason to hurry.
- Register for VAT when you cross the threshold
- Late registration carries a fine and back-dated VAT.
- Issue a valid tax invoice for taxable supplies
- Failing to issue one carries a per-invoice penalty.
- Report and exchange invoices as required under Fawtara
- Once you are in scope, invoices outside the system are not compliant.
- Calculate VAT correctly
- Errors mean repayment plus a percentage-based fine.
- Retain records for the statutory period
- Failure to retain creates both a fine and audit exposure.
Based on Oman's VAT Law (Royal Decree 121/2020) and the Tax Authority's executive regulations. Penalty amounts and their application are set by the Authority — confirm specifics with them or a licensed tax advisor.
The point of preparing early isn't avoiding a fine. It's that a business with clean data and current books never gets near one.

FAQ
Frequently asked questions.
What is e-invoicing in Oman?
The issuance, exchange and reporting of tax invoices in a structured electronic format through the Tax Authority's Fawtara system. Paper invoices and ordinary PDFs don't satisfy the requirement.
Who has to comply?
All VAT-registered businesses in the Sultanate, applied in stages. The Tax Authority confirms which businesses are included and when — confirm your own position with them. Preparation should not wait on that confirmation.
What is PINT OM?
Oman's national adaptation of the Peppol International invoice specification. It defines the fields, structure and rules your invoice data must follow.
Is Arabic required on the invoice?
The structured file follows the specification set by the Tax Authority. Bilingual Arabic/English readable copies are standard practice and we produce them by default.
How long must invoices be retained?
For the period set out in Oman's tax law. Invoices are archived in their original structured format with an audit trail.
How long does implementation take?
For a typical SME with clean books and a common accounting system: a few weeks. With a backlog, incomplete customer data or an unusual system: months.
Can I keep my existing accounting system?
In most cases yes. See our integrations page for the systems we connect.
Do I need a service provider?
Businesses in scope exchange and report through a service provider — either directly, or through accounting software that connects via one.
What happens if an invoice is rejected?
It isn't accepted onto the network and must be corrected and resent. We monitor for rejections and fix them, rather than leaving you to find them.
Does this apply to B2C invoices?
B2C invoices are within the published scope. Requirements for the readable copy differ from B2B — confirm the current position for your sector with the Authority.
