Once your Fawtara phase date passes, e-invoicing stops being a "when we get to it" project. Here's what non-compliance actually means, and what it costs.
What counts as non-compliance
In practical terms, once your phase applies to you, non-compliance includes:
- Not issuing invoices as compliant PINT-OM documents through the Peppol network (see our format explainer for what "compliant" actually means).
- Not submitting the required Tax Data Document to OTA for a transaction — a separate obligation from delivering the invoice itself, as we cover in our complete Fawtara guide.
- Not retaining invoice records for the required period (10 years generally, 15 for real estate, under Article 70 of Royal Decree 121/2020).
- Continuing to issue only paper or unstructured-PDF invoices past your phase's effective date.
The penalty framework
Here's an important distinction: Tax Authority Decision No. 189/2026 — the decision that created the e-invoicing mandate — doesn't set its own penalty amounts. It creates the obligation; enforcement runs through the existing VAT penalty framework that already applies to invoicing failures generally.
Based on published legal analysis of that framework (not yet independently cross-checked against OTA's own guidance — treat these figures as reported, not confirmed, and verify directly with OTA or a tax advisor before relying on them):
- Article 202 of the VAT Law's Executive Regulations reportedly covers general non-compliance, with fines cited in the OMR 500 to OMR 5,000 range per infraction, and potential business suspension for serious or repeated violations.
- Article 100 of the VAT Law reportedly covers deliberately refusing to issue a required tax invoice specifically — cited penalties include imprisonment of two months to one year, a fine of OMR 1,000 to OMR 10,000, or either.
We're deliberately citing these as "reported" rather than stating them as settled fact — OTA hasn't published a Fawtara-specific penalty schedule as of this writing, and this guide won't put a number in front of you that we can't trace to the primary source ourselves. Confirm the current figures with OTA directly, or a licensed tax advisor, before treating any specific amount as your actual exposure.
The business risk beyond the fine
A fine is the visible cost. The less visible ones matter more for most businesses:
- Your own compliance record has a gap the day your phase date passes if you're not issuing compliant invoices — this isn't a grace period, it's exposure that accrues from day one.
- Buyers on the Peppol network may not be able to process your invoices at all if they're not delivered in the correct format — that's a cash-flow problem (delayed payment) before it's ever a fines problem.
- Retroactive fixes are harder than getting it right the first time. Re-issuing historical invoices in the correct format, after the fact, once you notice a gap, is real operational work you don't control the timing of.
How to get ahead of it
- Confirm your phase date now — see our self-check.
- Don't wait until the month before your deadline to start; accredited providers and Access Points have limited onboarding capacity as everyone's deadline converges.
- Verify your provider (or in-house build) actually produces compliant PINT-OM output before you're relying on it — see our OTA-accredited service provider guide for how to check.
- If you're a smaller business on the Phase 2 date, see our Phase 2 survival guide for SMEs for a realistic, non-enterprise-scale prep plan.
