Electronic Invoicing Tunisia 2026: Complete Guide for Service Providers | El Fatoora TTN Compliance

Tunisia's Digital Fiscal Revolution

Tunisia is accelerating its digital transformation with the mandatory expansion of electronic invoicing to the entire services sector effective January 2026. This significant regulatory shift, established under Article 53 of the 2026 Finance Law, represents one of the most substantial changes to Tunisian business operations in recent years. With over 380,000 service providers now required to adopt the El Fatoora platform managed by Tunisie TradeNet (TTN), understanding compliance requirements has never been more critical.

Legal Framework Evolution

The electronic invoicing mandate builds upon existing legislation that began with the 2016 Finance Law (Article 22) and implementing Decree 2016-1066, which designated Tunisie TradeNet as the authorized platform operator. The 2026 Finance Law specifically expands mandatory electronic invoicing to cover all service provision activities, amending Article 18 of the VAT Code to include "service delivery operations" alongside previously regulated transactions.

Key Legislative Timeline:

• 2016: Initial electronic invoicing framework established

• 2025: Strengthened penalty regime introduced

• 2026: Mandatory expansion to entire services sector (Article 53)

Who Is Affected? Scope of Mandatory Compliance

Effective January 2026, the following entities must implement electronic invoicing through the El Fatoora platform:

Primary Obliged Parties:

• All service sector companies under the real tax regime

• Liberal professions: Lawyers, accountants, doctors, architects, engineers, consultants

• Service providers: Hotels, travel agencies, transportation companies, cleaning services

• Commercial and industrial enterprises (previously regulated since 2016)

Estimated Impact:

• 380,000+ businesses and professionals affected

• Sector coverage: Approximately 85% of Tunisia's service economy

• Timeline: Full implementation required by January 1, 2026

Penalties for Non-Compliance: Financial Risks

The 2025 Finance Law established substantial penalties for non-compliance, with the 2026 expansion bringing these sanctions to the entire service sector:

Monetary Penalties:

1. Paper invoice issuance instead of electronic format: 100-500 dinars per invoice (maximum 50,000 dinars annually)

2. Non-compliant electronic invoice: 250-10,000 dinars, doubled for repeat offenses

3. Goods transportation without valid invoice: 20% of transaction value (minimum 500 dinars)

Additional Consequences:

• Tax audit triggers and increased scrutiny

• Exclusion from public tenders and government contracts

• Administrative sanctions from regulatory authorities

Technical Requirements: The TEIF Format
