What Happens If You Miss the E-Invoicing Deadline? Penalties Across Oman, France, and Germany

Oman: Penalties Sit Inside the VAT Law

Oman's Fawtara system follows a Peppol-based 5-corner model under the Oman Tax Authority (OTA). The rollout runs in four phases: Phase 1 in August 2026 (around 100 of the largest VAT-registered companies), Phase 2 in February 2027 (remaining large taxpayers), Phase 3 in August 2027 (all other VAT-registered businesses including SMEs), and Phase 4 in 2028 for government entities. The OTA has launched a public Rollout Checker at tms.taxoman.gov.om/portal/rollout-checking, allowing any business to enter its VATIN and confirm its assigned phase.

The OTA has not published a Fawtara-specific penalty schedule. Enforcement runs through the existing VAT Law (Royal Decree 121/2020):

• Failure to issue a tax invoice: 50% of the tax due, minimum OMR 50 per offense.
• Deliberate refusal to issue invoices or maintain records: OMR 1,000 to 10,000, or imprisonment of 2 months to 1 year, or both.
• Deliberate failure to register or file returns: OMR 5,000 to 20,000, or imprisonment up to 3 years. Repeat violations can double the penalty.
• Late VAT payment: 1% per month on the unpaid amount.
• Late VAT return filing: OMR 500 to 5,000.
• Tax evasion or fraud: Fines up to OMR 20,000 and imprisonment up to 3 years.

E-invoices must be archived for 10 years (15 for real estate). Record-keeping failures invite fines of OMR 1,000 to 5,000.

France: Per-Invoice Fines Under the Finance Act 2026

France enforces its mandate on a phased schedule. From 1 September 2026, all businesses must be able to receive e-invoices, and large and mid-sized companies (ETI) must also issue them. SMEs and micro-enterprises follow on 1 September 2027.

The penalty regime was formally revised by the Finance Act 2026 (Law No. 2026-103 of 19 February 2026), which amended Articles 1737 and 1788 D of the Code Général des Impôts (CGI) and introduced a new Article 1737 IV bis. The previous rates of €15 per invoice and €250 per e-reporting transmission have been increased:

• E-invoicing non-compliance (Article 1737 III CGI) : €50 per invoice, capped at €15,000 per calendar year.
• E-reporting non-compliance (Article 1788 D CGI): €500 per missing or late transmission, capped at €15,000 per year per category.
• Failure to designate an Approved Platform (Article 1737 IV bis CGI): A new sanction. After formal notice, businesses have three months to designate a Plateforme Agréée (PA). Failure triggers a €500 fine, then €1,000 every three months until regularised.
• VAT deduction risk: Invoices that fail Factur-X, UBL, or CII format requirements can be challenged in audits.

A critical clarification on timing: an earlier amendment (I-1028) proposed a two-year good-faith grace period through 31 August 2028. This was not retained in the final adopted law. Penalties apply from go-live in September 2026. There is also an operational risk beyond the formal regime: if a French buyer cannot find your business in the PPF central directory, they cannot pay you through the e-invoicing flow at all.

Germany: Lower Headline Fines, Sharper Indirect Pain

Germany's mandate, introduced through the Wachstumschancengesetz (Growth Opportunities Act) , uses a decentralized post-audit model. Every business has had to be capable of receiving EN 16931-compliant e-invoices since 1 January 2025. Companies with turnover above €800,000 must issue them from 1 January 2027, and all remaining businesses from 1 January 2028.

No penalties are imposed during the 2025–2026 transition while paper and PDF invoices remain accepted with recipient consent. Once the issuing mandate applies, the regime sharpens:

• Failure to issue a compliant e-invoice: Up to €5,000 per offense under §26a UStG. Each non-compliant invoice can count as a separate offense.
• Denial of input VAT deduction: The most damaging consequence in practice. Buyers receiving non-compliant invoices cannot recover VAT until a corrected e-invoice is issued, so they will simply refuse to pay.
• Archiving violations: Structured e-invoices must be stored in original format for 8 years.
• Small-business exemption: Businesses with turnover up to €22,000 under §19 UStG are exempt. Invoices below €250 are also exempt. The €5,000 cap looks modest, but the cumulative effect of denied VAT deductions across thousands of transactions makes the practical cost much higher.

How the Three Regimes Compare

What This Means for Your Business

Direct fines are the smallest part of the exposure. The bigger losses come from denied VAT deductions, blocked receivables, and audit findings that trigger broader investigations.

The operational deadline is earlier than the legal deadline. Selecting an accredited service provider, integrating ERP systems, and running parallel cycles takes months. France has already removed its proposed grace period, signalling that exposure begins at go-live.

Compliance is a governance issue, not an IT project. Regulators in all three jurisdictions treat repeated invoicing failures as evidence of weak internal controls, which shifts accountability to leadership. The deadline is not the moment compliance begins. It is the moment non-compliance starts costing money.
