VAT liability refers to the tax status of any person who independently engages in an economic activity, whether commercial, artisanal, liberal, or agricultural. This status does not depend on the legal form of the business or its turnover: it arises from the very nature of the activity performed. Understanding this mechanism allows one to anticipate their reporting and invoicing obligations.
Self-assessment and debtor status: the mechanism that classical definitions overlook
Most resources on VAT stop at the distinction between liable and debtor. They overlook a third role: that of tax debtor. The debtor is the person who physically pays the VAT to the public treasury, and this is not always the supplier.
According to the BOFiP doctrine in effect as of September 9, 2026, certain operations carried out for clients who are VAT liable and identified in France fall under a general self-assessment mechanism. Specifically, the VAT is not collected by the supplier but declared by the client. The supplier remains liable, the client is the debtor, and it is the latter who becomes the debtor.
This mechanism particularly concerns services provided by businesses established outside France to French VAT liable clients. It also applies to certain deliveries of goods in the context of intra-community operations. To understand VAT liability, one must go beyond the simple question “am I liable?” and identify who, in each transaction, bears the reporting burden.
Liable without being debtor: the case of VAT exemption
A business can be VAT liable without ever charging it to its clients. This is the principle of VAT exemption. This regime is aimed at businesses whose turnover remains below certain thresholds set by the General Tax Code.
Under this regime, the business does not collect VAT and does not remit it. In return, it cannot deduct the VAT incurred on its professional purchases. The mention “VAT not applicable, article 293 B of the CGI” must appear on every issued invoice.
This point often creates confusion: many micro-entrepreneurs believe they are not liable. They are, but they are not debtors as long as they remain within the limits of the exemption. The day the threshold is exceeded, VAT becomes payable, sometimes retroactively for the month of the excess.
Practical consequences of exceeding the threshold
Transitioning to liability involves several simultaneous adjustments:
- Modifying all invoicing documents to include the collected VAT, with the applicable rate for each transaction
- Declaring and remitting VAT according to the frequency corresponding to the tax regime (monthly or quarterly)
- Exercising the right to deduct the VAT incurred upstream, which requires keeping and organizing all compliant purchase invoices
Elimination of the simplified VAT taxation regime in 2027
The tax administration announced on September 23, 2026, the elimination of the simplified VAT taxation regime effective January 1, 2027. This regime allowed the affected businesses to submit only an annual declaration (CA12) accompanied by semi-annual payments.
Its disappearance means that businesses benefiting from it will have to switch to the normal real regime, with monthly or quarterly declarations. The change does not alter the liability status, but it increases the administrative reporting burden.
For small structures accustomed to a lighter tax management, this transition requires adapting their accounting tools and cash flow. Flat-rate payments disappear in favor of declarations reflecting the VAT actually collected and deducted for each period.
Electronic invoicing and liability: the deadline of September 2026
The obligation for electronic invoicing directly concerns businesses liable for VAT, including those benefiting from the VAT exemption. A BOFiP update published on September 30, 2026, sets an initial deadline of September 1, 2026, for large enterprises and medium-sized businesses.
Even a business under VAT exemption must receive invoices in electronic format via a partner dematerialization platform. Liability thus creates technical obligations independent of the actual collection of the tax.
What this changes on a daily basis
Invoice flows between liable parties (domestic B2B operations) must go through certified platforms. Each invoice issued or received generates e-reporting or e-invoicing depending on the nature of the operation and the status of the parties.
- Liable parties issue and receive their invoices via a partner dematerialization platform or the public invoicing portal
- Non-liable parties (VAT exemption) must at least be able to receive electronic invoices
- Operations with non-liable parties (individuals) are subject to e-reporting sent to the tax administration
The gradual deployment schedule means that all liable businesses will eventually be affected, regardless of their size. The liability status now determines both invoicing obligations and reporting obligations. Anticipating technical compliance avoids penalties and disruptions in commercial flows with partners who are already equipped.
