VAT self-liquidation: cases, rules and errors
Updated March 2026 - The VAT reverse charge does not apply to a single case. In practice, it may concern importation, certain purchases made from a taxable person not established in France or even subcontracting in construction. The common point is simple: the person liable for VAT is not the one who invoices tax inclusive, but the one who must declare and remit the tax according to the mechanism provided for by the CGI.
The main cases of reverse liquidation to know
The official pages of impots.gouv.fr recall three major situations in particular:
- ▸self-liquidation of import VAT;
- ▸self-liquidation on purchases of goods or services made from a taxable person not established in France;
- ▸self-liquidation on subcontracting in construction.
Self-liquidation on import
Since 2022, self-charge of import VAT has become the norm for VAT payers in France. This requires suitable registration and a good reading of the CA3, because the amount of import VAT is now pre-filled from customs data.
Services with a supplier not established in France
When you purchase certain services or certain goods from a taxable person not established in France, you must check whether the territoriality rule leads to self-liquidation by the French customer. The invoice can then be issued excluding tax, but the VAT does not disappear: it is simply declared differently.
Construction subcontracting
The self-liquidation mechanism in building subcontracting remains a classic control point. An error in invoicing or qualification of the contract is enough to create a risk of recovery.

Hayot Expertise Advice: In VAT, a poorly written invoice can contaminate the entire chain: accounting, CA3 declaration, supplier relations and tax audit. Self-liquidation must be configured, not improvised.
The most frequent errors
- ▸charge French VAT when the transaction must be self-liquidated;
- ▸omit the registration useful for importation;
- ▸confuse importation, intra-community acquisition and international service;
- ▸forget the connection with the CA3.
