VAT 2026: calculation, declaration and new obligations for businesses

VAT 2026: calculation, declaration and new obligations for businesses

VAT remains the most collected tax in France, generating approximately 200 billion euros in annual revenue. In 2026, several major changes are simultaneously modifying the calculation rules, declaration obligations and audit procedures. Between the extension of mandatory electronic invoicing, the deployment of e-reporting and the adjustments to tax rates introduced by the finance law, accounting and finance departments must prepare now. This article covers everything you need to know: the tax base, applicable rates, declaration schedule and non-compliance risks.

The fundamentals of VAT calculation in 2026

The mechanics of VAT rest on an unchanged principle: the business collects the tax on behalf of the State from its customers, then deducts the VAT it has itself paid on its purchases. The balance is paid to the State Treasury—or refunded if deductible VAT exceeds collected VAT.

The taxable base: what enters into the calculation base

The VAT tax base is the price excluding tax for the transaction, increased by all ancillary charges invoiced: transport fees, packaging, insurance, interest on deferred payment and subsidies directly linked to the price. Since the European Directive 2006/112/EC was transposed into French law, early payment discounts granted at the time of invoicing may be deducted from the tax base, provided that they are actually offered.

Attention: late payment penalties and damages are not subject to VAT insofar as they do not remunerate the delivery of goods or provision of services.

VAT rates applicable in 2026

France maintains in 2026 its structure of four rates:

• Standard rate of 20%: applies to the vast majority of goods and services, including digital services and SaaS services.
• Intermediate rate of 10%: restaurant dining, renovation work, passenger transport, hotel accommodation.
• Reduced rate of 5.5%: essential food products, books, gas and electricity subscriptions, equipment and services for persons with disabilities, energy efficiency renovation work.
• Particular rate of 2.1%: medicines reimbursed by Social Security, periodical press registered with the Joint Commission.

The 2026 Finance Law did not modify the nominal rates, but it clarified the conditions for applying the 5.5% reduced rate to certain thermal renovation work, requiring the provision of a certificate of compliance with energy efficiency performance criteria defined by Decree No. 2025-421.

VAT on intra-Community transactions

With regard to exchanges within the European Union, the system for intra-Community acquisitions remains based on the destination principle: VAT is due in the country of arrival of the goods. For B2B services, the general rule sets the place of taxation as where the service recipient is established, in accordance with Article 259 of the General Tax Code (CGI).

Since 1 July 2021, the OSS (One Stop Shop) window has allowed businesses to declare and pay VAT due in all Member States through a single interface. In 2026, this mechanism is fully operational and its use is increasing significantly, particularly for e-commerce platforms.

New VAT declaration obligations in 2026

The year 2026 marks a turning point in declaration procedures, due to the effect of two converging reforms: the extension of mandatory electronic invoicing and the scaling up of the e-reporting system.

Mandatory electronic invoicing and its connection to VAT declaration

Since 1 September 2026, all businesses subject to VAT and established in France—including micro-businesses—are required to receive electronic invoices. Mandatory issuing is being implemented progressively based on company size: large businesses and large mid-market companies switched as of September 2026, SMEs and micro-businesses will follow according to the schedule detailed on the electronic invoicing calendar 2026-2027 page.

The direct consequence for VAT declaration is significant: the Directorate General of Public Finances (DGFiP) retrieves data from each transaction via partner digitization platforms (PDP) and the public invoicing portal (PPF). Ultimately, the tax authority will have an almost real-time view of VAT flows, which will allow pre-filling of VAT returns—similar to what already exists for income tax.

To understand the precise role of these platforms in the declaration chain, consult our guide on approved PDP platforms.

E-reporting: a new data transmission obligation

E-reporting complements electronic invoicing by covering transactions that do not fall directly within its scope: transactions with individuals (B2C), exchanges with foreign businesses not established in France, and transactions outside the scope of French VAT.

Concretely, businesses must transmit aggregated data to the tax authority on these transactions according to a frequency aligned with their VAT system:

• Monthly regime: transmission within 10 days following the close of the period.
• Quarterly regime: transmission within 10 days following the end of the quarter.

Failure to comply with these obligations exposes the business to penalties of up to 15 euros per missing invoice, up to a maximum of 15,000 euros per year per filer. For a comprehensive presentation of the system, our article on e-reporting and transaction data transmission details the expected file formats and deadlines.

Declaration regimes and their deadlines in 2026

The choice of declaration regime depends on annual turnover excluding tax:

Simplified real regime (RSI): available to businesses with annual turnover excluding tax below 840,000 € for commercial activities and 254,000 € for service provision. Two semi-annual installments (55% in July, 40% in December) and an annual CA12 return to be filed within 3 months following the close of the financial year.

Normal real regime (RRN): mandatory beyond RSI thresholds or by election. Monthly CA3 return, due on the 19th of the following month for businesses whose annual VAT liability exceeds 4,000 €.

VAT exemption for small businesses: maintained for micro-businesses with annual turnover excluding tax below 37,500 € for services and 85,000 € for trade. These thresholds were raised by the 2025 Finance Law and remain applicable in 2026.

Impact of the reform on accounting and internal processes

Adaptation of information systems

The convergence between electronic invoicing, e-reporting and VAT pre-filling requires that businesses align their management tools. An ERP or invoicing software that does not produce files in Factur-X or UBL format—the structured formats recognized by the tax authority—is now a blocking issue.

The Factur-X format deserves special attention: it is a PDF enriched with an embedded XML file, readable by humans and exploitable by machines. To verify the compliance of your invoices, our free Factur-X validator allows you to instantly check the structure of files before their emission.

Management of mandatory invoice information

In 2026, the mandatory information on invoices subject to French VAT has been expanded. In addition to standard information (SIREN number, intra-Community VAT number, due date, applied rate, amount excluding and including tax by rate), electronic invoices must now include:

• The SIREN number of the recipient (mandatory for B2B).
• The delivery address if different from the recipient's address.
• The category of the transaction (delivery of goods, provision of services, mixed).
• The purchase order number if mentioned in the contract.

The absence of one of these details may result in the invoice being rejected by the recipient's PDP, delaying payment and the right to deduct VAT.

VAT deductibility: rules and restrictions

The right to deduct VAT remains subject to three cumulative conditions: holding a valid invoice, the VAT being due from the supplier, and the good or service being used for the purposes of a taxable activity. The exclusions from the right to deduction codified in Article 206 of Schedule II of the CGI concern in particular:

• Passenger vehicles (except for rental or transport activities).
• Accommodation expenses for the benefit of managers and employees.
• Business gifts with a unit value exceeding 73 € including tax per year and per recipient (2026 threshold).

In the event of a tax audit, the DGFiP has had easier access since 2026 to data transmitted via PDPs, which strengthens the need for perfect consistency between issued invoices, received invoices and declared amounts.

Tax audit and redressment risks in 2026

Strengthened tax control through data

The generalization of electronic invoicing equips the tax authority with an unprecedented audit tool. By cross-referencing data transmitted by invoice issuers and recipients, the DGFiP can automatically identify inconsistencies: invoices recorded as expenses without VAT collected by the supplier, multiple deductions of the same invoice, applied rate incompatible with the nature of the transaction.

Tax audits relating to VAT already represent approximately 40% of adjustments resulting from accounting verifications. In 2026, accountancy experts anticipate an intensification of algorithmically generated targeted audits, similar to those conducted in the Netherlands or Spain for several years.

The main redressment risks

The most common reasons for VAT redressment are:

1. Incorrect rate: application of the reduced rate to a transaction subject to the standard rate, particularly for real estate work or take-away food service.
2. Incorrectly identified taxable event: confusion between delivery date and invoicing date for delivery of goods, or between receipt of payment and invoice date for services subject to VAT on collections.
3. Omission of VAT on benefits in kind or transactions between companies of the same group.
4. Undue deductions on invoices not meeting mandatory information requirements or from suppliers in irregular situation.

For businesses engaged in complex transactions (intra-Community, reverse charge, special regimes), a prior compliance audit often proves cost-effective given the penalties incurred: 40% increase for deliberate non-compliance, 80% for fraudulent conduct, in addition to late payment interest of 0.20% per month.

The connection between electronic signature and tax compliance is direct: an invoice signed electronically in accordance with eIDAS standards guarantees the authenticity of origin and integrity of content, two of the three conditions set by the VAT Directive for deductibility. To learn more, our comprehensive guide to electronic invoicing 2026-2027 presents the entire regulatory ecosystem.

Applicable legal framework for VAT and electronic invoicing in 2026

French VAT is part of a multi-level legal framework, European and national, whose mastery determines the validity of deductions and robustness against audits.

VAT Directive 2006/112/EC: founding text harmonizing VAT rules within the European Union. It sets the principles of tax base, minimum rates (5% for the reduced rate, 15% for the standard rate), deductibility and due date. Any national rule must comply with it.

General Tax Code (CGI): Articles 256 to 293 organize French VAT rules. Article 289 defines mandatory invoice information. Articles 271 to 273 govern the right to deduct. Article 283 sets out reverse charge rules.

Ordinance No. 2021-1190 of 15 September 2021: relating to the generalization of electronic invoicing in B2B transactions. Modified by the 2024 Finance Law, it sets the deployment schedule by wave and e-reporting obligations.

Decree No. 2022-1299 of 7 October 2022: specifies the technical formats of electronic invoices (Factur-X, UBL, CII) and the minimum data required for e-reporting.

Regulation eIDAS No. 910/2014 of the European Parliament and of the Council: establishes the legal framework for qualified electronic signatures, whose evidentiary value is equivalent to a handwritten signature throughout the EU (Article 25). A qualified electronic signature affixed to an invoice meets the requirement for authenticity of origin set by the VAT Directive, provided it is issued by a qualified trust service provider (QTSP) listed on the national trust list.

GDPR No. 2016/679: the transmission of invoicing data between businesses and to the tax authority involves the processing of personal data (names, contact details). The data protection officer (DPO) must be involved in electronic invoicing compliance projects.

NIS2 Directive (2022/2555/EU): transposed into French law by Law No. 2023-703, it imposes strengthened security requirements on essential service operators and digital service providers, including PDPs. Businesses that outsource their invoicing flow via a PDP must contractually ensure that it meets NIS2 obligations.

ETSI standards EN 319 132 and EN 319 122: technically govern advanced (XAdES) and qualified electronic signatures used to timestamp and secure electronic invoices. Compliance with these standards determines the admissibility of evidence in the event of dispute or tax audit.

Use scenarios: how businesses are adapting to 2026 VAT rules

An IT services SME facing e-reporting

An SME with approximately sixty employees, specializing in IT managed services and application development, generates about 30% of its turnover from customers established outside France (European businesses and individual customers). These flows—not covered by mandatory domestic B2B electronic invoicing—fall within the scope of e-reporting as of 1 September 2026.

Following a three-week internal audit, the accounting department identifies that its ERP generates CSV exports that do not comply with DGFiP technical specifications. Updating the PDP connector and training two employees represents an investment of approximately 8,000 €. In return, automatic reconciliation of declared and collected data reduces VAT return preparation time from 6 hours to less than 1 hour per month, a saving estimated at 3,500 € per year in accounting time.

An accounting firm managing clients with different regimes

An accounting firm with 25 employees supports a mixed client base: merchants on simplified real regime, self-employed professionals with VAT exemption for small businesses and industrial companies on normal real regime. In 2026, the firm must simultaneously manage three declaration logics and ensure that each client transitions at the right time to mandatory receipt of electronic invoices.

The firm adopts a centralized electronic invoicing flow management solution connected to its case management platform. For clients with VAT exemption for small businesses, it documents the obligation to receive even in the absence of obligation to issue—a point often misunderstood. Collective compliance allows negotiating grouped pricing with an approved PDP, reducing per-client cost by 35% compared to individual subscriptions.

A B2B distributor dealing with intra-Community VAT reconciliation

A distributor of industrial equipment with 18 million euros in turnover excluding tax makes intra-Community acquisitions from suppliers in Germany, Italy and Poland, and conducts intra-Community deliveries to customers in Belgium and the Netherlands. In 2026, the generalization of electronic reporting in these partner countries creates a risk of double declaration if data transmitted to respective authorities is not consistent.

By deploying a dedicated module for intra-Community transactions in its management system, the company automates verification of intra-Community VAT numbers via the Commission's VIES (VAT Information Exchange System) service, checks the compliance of partner VAT numbers, and automatically generates summary statements (DEB/DES replaced by the European Declaration of Trade in Goods). This automation reduces declaration anomalies by nearly 70% over the first six months of operation, according to internal monitoring conducted by the accounting manager.

Frequently asked questions

How do you calculate the VAT to be paid for a given period?

The VAT to be paid equals the VAT collected (amount excluding tax from sales multiplied by the applicable rate) minus deductible VAT (VAT appearing on eligible professional purchase invoices). If collected VAT is higher, the business pays the balance to the tax authority. If deductible VAT is higher, it can request a refund or carry forward the credit to the following period.

What is the difference between VAT on invoicing and VAT on collections?

VAT on invoicing is due upon invoice issuance, regardless of actual payment. This is the general rule for delivery of goods. VAT on collections, applicable to services (unless otherwise elected), is due only upon actual receipt of payment. This choice has a significant impact on cash flow, especially in cases of long payment delays.

Which businesses are affected by e-reporting in 2026?

All businesses subject to VAT in France are affected by e-reporting as soon as they conduct transactions not covered by B2B electronic invoicing: sales to individuals, transactions with foreign businesses not established in France, or VAT-exempt transactions. Micro-businesses with VAT exemption for small businesses do not collect VAT but remain subject to certain transmission obligations if they exceed transitional thresholds.

Is the VAT exemption for small businesses modified in 2026?

No. The thresholds for VAT exemption for small businesses set by the 2025 Finance Law remain unchanged in 2026: 85,000 € excluding tax for sales and housing provision activities, 37,500 € excluding tax for service provision. Businesses with exemption benefit from tolerance for maintenance up to 93,500 € and 41,250 € respectively. They do not collect VAT but are subject to the obligation to receive electronic invoices as of September 2026.

How does electronic signature guarantee VAT deductibility on an invoice?

According to VAT Directive 2006/112/EC, an invoice must guarantee the authenticity of its origin and the integrity of its content to grant the right to deduct. A qualified electronic signature within the meaning of Regulation eIDAS No. 910/2014 meets these two requirements: it identifies the issuer with certainty and detects any subsequent modification of the document. In the event of a tax audit, an invoice signed electronically with a qualified certificate constitutes strong proof that the tax authority cannot contest.

Conclusion

VAT 2026 is not a simple regulatory update: it is a profound overhaul of the calculation, declaration and audit procedures, driven by the convergence between mandatory electronic invoicing and e-reporting. Businesses that anticipate these changes—by adapting their information systems, securing invoice compliance and training their teams—will transform a regulatory constraint into an operational advantage.
