Monaco’s VAT system has seen few substantive changes of its own during the first half of 2026. Unlike a number of other European microstates, the Principality does not operate an independent VAT policy framework and therefore has no separate rate changes, exemption reforms, or VAT incentives to report. Instead, the main development affecting businesses this year is France’s e-invoicing reform, which begins taking effect from September 2026 and extends to many Monegasque businesses because of Monaco’s longstanding VAT integration with France.
A treaty-based VAT system
Monaco’s VAT system is governed by the Franco-Monegasque Tax Convention of 18 May 1963, implemented domestically through Sovereign Ordinance No. 3037 of the same year. Under this framework, turnover taxes are applied in Monaco on substantially the same bases and at the same rates as in France.
To maintain that alignment, Monaco periodically adopts legislative updates reflecting changes made in France. The most recent example was Sovereign Ordinance No. 10.832 of 19 September 2024, which incorporated amendments corresponding to French VAT reforms that took effect from 1 January 2024.
The resulting legislation, the Code des taxes sur le chiffre d’affaires (CTCA), forms Monaco’s domestic VAT code. In practice, however, it largely mirrors the corresponding provisions of the French tax system.
Under the same convention, Monaco receives a share of VAT revenues collected under the Franco-Monegasque arrangement. Published estimates place these annual transfers at approximately €100 million.
France’s e-invoicing reform becomes Monaco’s main VAT issue
France’s mandatory e-invoicing and e-reporting regime begins its first phase on 1 September 2026 for large and medium-sized businesses, with smaller businesses following in September 2027.
Because Monaco forms part of the same VAT territory as France rather than being treated as a third country, the reform has direct implications for many businesses operating in the Principality.
Whether a Monegasque business falls within the French e-invoicing perimeter depends largely on its registration status with the French tax authorities, including registration through the SIE de Menton. Where a business falls within scope, transactions may be subject to the e-invoicing requirements set out in Article 289 bis of the French General Tax Code. Other transactions may instead be covered by France’s parallel e-reporting obligations.
Businesses also have the option of voluntarily participating in the e-invoicing framework, which may simplify transactions with French customers and suppliers.
Several technical considerations arise for cross-border transactions, including specific documentary requirements for deliveries into Monaco and the interaction between French and Monegasque registration statuses.
Preparation within Monaco
A number of developments suggest that businesses and public institutions in Monaco are already preparing for implementation.
Local business publications have increasingly focused on the September 2026 deadline and the transition to structured electronic invoice formats such as Factur-X, UBL and CII. Compliance advisers and software providers have likewise developed services aimed specifically at businesses operating between Monaco and France.
Public-sector initiatives are also visible. The Mairie de Monaco operates an electronic supplier-invoicing portal through which vendors can submit invoices digitally. According to the municipality, the initiative forms part of a broader digital-transformation strategy intended to reduce paper-based administration and improve invoice-processing efficiency.
The platform operates through the Municipal Expenditure Control department and incorporates both GDPR requirements and Monaco’s own data-protection framework under Law No. 1.165 of 23 December 1993, as amended.
The first phase of France’s e-invoicing reform takes effect on 1 September 2026. For affected businesses, the remaining months before implementation are likely to be focused on reviewing registration status, invoicing processes, and reporting obligations under the new framework.
