Construction 2026: VAT reverse charge in subcontracting

Quick answer. In construction subcontracting, the subcontractor invoices VAT-free, with no VAT, and adds the wording « Autoliquidation » (reverse charge). It is the main contractor, a taxable customer, who accounts for the VAT: they report it as output VAT and deduct it under ordinary rules. The mechanism is mandatory.

On construction sites, the subcontracting chain remains a recurring source of friction. A subcontractor who invoices with VAT when reverse charge applied, a main contractor who forgets to account for the tax, a missing wording on the invoice: these simple mistakes trigger payment rejections, follow-ups and, at times, reassessments. In 2026, they take on a new dimension with the gradual rollout of e-invoicing.

This article sets out the regime applicable in 2026: what the VAT reverse charge means in construction, who must apply it, how to invoice correctly, and why configuring your invoicing tool becomes a compliance matter in its own right. We write as a chartered accountancy firm registered with the Ordre des experts-comptables, in daily contact with construction businesses.

The VAT reverse charge in construction is set out in article 283, 2 nonies of the French General Tax Code (CGI), in force since 2014. The principle flips the usual VAT mechanics: it is no longer the provider who collects and remits the tax, but its customer.

The scheme covers construction, repair, cleaning, maintenance, transformation and demolition works on immovable property, when carried out by a subcontractor for a customer, the main contractor, who is itself liable to VAT.

In practice, the subcontractor adds no VAT to its invoice. The main contractor reports that VAT as if it had collected it, and deducts it at the same time under ordinary rules. The operation is cash-neutral for the main contractor where it has a full right to deduct, but it requires a correct declaration.

The three cumulative conditions#

For the reverse charge to apply, three conditions must be met at the same time. If one is missing, the standard regime of invoicing with VAT applies.

The most common misunderstanding is about the allocation of roles. The rule is clear: the subcontractor never invoices VAT to the main contractor within the scope of article 283, 2 nonies.

The main contractor applies to the project owner the VAT rate set for the nature of the works. We do not quote any figure here, as it depends on the type of operation and must be checked case by case with your adviser. The structural point is this: VAT is not absent, it simply changes who is liable at the subcontracting stage.

Here is the sequence we recommend to the subcontractor to secure its invoicing.

1. Check that you are indeed acting as a subcontractor, for a taxable main contractor, on targeted immovable works.
2. Issue the invoice VAT-free, with no VAT line, showing the net amount as the amount payable.
3. Display the wording « Autoliquidation » clearly on the invoice.
4. Keep a record of the nature of the works and of your customer's taxable status, in case of an audit.
5. On the main contractor side, report the reverse-charged VAT on your return: as output VAT and, symmetrically, as deductible VAT.

The following checklist helps make sure nothing is missed when issuing or receiving the invoice:

• The subcontracting relationship is documented by a contract or a purchase order.
• Both parties are liable to VAT in France.
• The subcontractor's invoice is VAT-free.
• The wording « Autoliquidation » is present and accurate.
• The main contractor has configured its return to report the reverse-charged VAT.

Wording and conditions to check#

Many small subcontractors think that, by benefiting from the basic VAT exemption (franchise en base), they are out of scope. That is wrong. Even a subcontractor under the VAT exemption must invoice using the reverse charge where it works as a subcontractor for a taxable main contractor.

The exemption removes the obligation to charge VAT on its own sales, but it does not block the reverse-charge mechanism, which shifts the reporting obligation to the main contractor. A subcontractor under the exemption therefore invoices VAT-free with the wording « Autoliquidation », just like a liable taxable person.

In our files, this point regularly causes confusion. A tradesperson under the exemption reasons « no VAT, so no wording »: the invoice goes out without the reverse-charge wording, and the main contractor returns it or blocks payment. The correct reflex is the opposite: exemption or not, in immovable subcontracting, the wording is due.

A common case seen in the firm. A subcontractor invoices correctly VAT-free with the wording « Autoliquidation ». The main contractor, unfamiliar with the scheme, records the invoice as an expense without reporting the reverse-charged VAT on its return. It has therefore reported neither output VAT nor deductible VAT on these operations.

In the absence of reverse-charged output VAT, the main contractor is exposed to a reassessment on the undeclared VAT. The fact that the operation is cash-neutral where the right to deduct is full does not remove the reporting obligation. Good practice is to set up, in the accounts, a dedicated posting scheme for reverse-charged subcontracting invoices, so that the output and the deduction are recorded systematically.

The 2026 news does not lie in a change to article 283, 2 nonies, which remains the applicable regime, but in the e-invoicing reform. From 1 September 2026, all businesses must be able to receive electronic invoices in a compliant format.

This changes things for construction, a sector with many subcontracting flows. An invoice whose reverse-charge wording is missing, misplaced or wrong can be rejected by the receiving platform or become a source of reassessment. Compliance in form joins compliance in substance.

In practice, configuring your invoicing tool becomes a matter in its own right: the software must be able to produce a VAT-free subcontracting invoice carrying the wording « Autoliquidation » correctly, in an accepted format. To understand the sequencing of the reform, we refer you to our e-invoicing calendar 2026-2027 and to our summary of the key measures from 1 January 2026 for businesses.

On this topic, the points of attention in case of an audit are fairly constant. The authorities check the consistency between the real nature of the relationship, its qualification as subcontracting and the VAT treatment applied.

• The reality of the subcontracting, as opposed to a direct service to the project owner.
• The presence and accuracy of the wording « Autoliquidation » on the subcontractor's invoices.
• The actual reporting of the reverse-charged VAT by the main contractor, as output and deductible.
• The taxable status of both parties.

The reverse-charge regime has been stable and well established since 2014. The real challenge in 2026 is not legal but operational: it plays out in the configuration of tools and in invoicing discipline. Construction businesses that anticipate the obligation to receive electronic invoices by cleaning up their invoice templates and accounting schemes now will avoid payment blockages and corrections.

For structures handling a large volume of subcontracting, the cash-flow and tracking stakes often justify steering support. This is one of the points we handle as part of our outsourced finance director engagements, alongside the accounting and tax support offered by our chartered accountancy firm in Paris 8.
