VAT on debits or on payments: which choice in 2026?

Quick answer. The choice of VAT on debits or on payments mainly concerns service providers. By default, VAT becomes chargeable on collection, which protects your cash flow. By opting for debits, you bring chargeability forward to invoicing: simpler management, but you advance VAT on invoices that are not yet paid.

You invoice a service in March, your client pays in June, and the tax authority asks you to remit the VAT. At exactly which point? This seemingly technical question has a direct impact on your cash flow and on how simple your bookkeeping is. The debate over VAT on debits or on payments comes up constantly in the files of service providers, consultants, agencies and professional practices. Here is how chargeability works, what the option changes, and how to decide.

Chargeability is the moment when the VAT you have collected must be remitted to the State, and therefore the moment it enters your return. It is not necessarily the moment you issue the invoice, nor the moment you are paid. Everything depends on the nature of the transaction.

Two broad categories must be distinguished: supplies of goods and supplies of services. The rules are not the same, and confusing the two is one of the most common mistakes we encounter.

For a sale of merchandise or products, VAT becomes chargeable on delivery of the goods. The debits-or-payments choice therefore does not arise in the same way as for services.

Since 1 January 2023, an important nuance applies: collecting an advance on a supply of goods makes the VAT chargeable as soon as the advance is collected. This reform, from the 2022 finance act, transposes European case law. Concretely, if you receive an advance before delivering, you must declare the corresponding VAT for the collection period, without waiting for delivery.

If your activity combines sales of goods and services (a frequent case, for instance an installer who sells equipment and invoices the fitting), each flow follows its own rule. We check this systematically during accounting bookkeeping and review, because incorrect allocation shifts the VAT to the wrong period.

For supplies of services, VAT is in principle chargeable on collection of the price or of advances. This is the regime known as VAT on payments, set out in article 269-2-c of the general tax code.

The logic favours cash flow. You only remit VAT once the price is collected. If an invoice remains unpaid, you do not have to advance the corresponding VAT. In return, this regime requires careful tracking of collections: you must attach each payment to the right period, which assumes clean matching between invoices and payments.

A service provider may opt to account for VAT on debits. The debit corresponds to the entry of the amount in the debit of the client account, which in practice coincides with invoicing. The option therefore brings VAT chargeability forward to the moment you issue the invoice, rather than the moment you are paid.

One limit is essential to understand: the option can never postpone chargeability. If an advance is collected before the invoice, VAT remains chargeable as soon as that advance is collected. In other words, the option for debits only brings chargeability forward, never pushes it back.

The mandatory mention on the invoice#

Where you opt for debits, the wording VAT accounted for on debits must appear on your invoices. This wording informs the client of the applicable regime and underpins the consistency of VAT deduction on their side. Omitting this mention is one of the most common friction points: your invoicing software must generate it automatically. If you are working on this, our article on the mandatory invoicing software in 2026 and the one on electronic invoicing 2026 for SMEs detail the mentions to secure.

In the files we follow, the decision often comes down to two opposing priorities: protecting cash flow or simplifying management.

The payments regime is valuable when payment terms are long or when unpaid invoices are possible. You only remit VAT after being paid, which avoids advancing VAT on invoices that do not come in. This is often the right choice for a young activity with tight cash flow.

The debits option appeals to structures that want to align their VAT with their invoicing, without having to track collections finely. It also eases deduction on the client side, which can be a commercial argument in B2B relationships. The trade-off is a cash advance: you remit VAT as soon as you invoice, even if the client pays later.

The most common trap is not the choice itself, but the inconsistency between the declared option and actual practice. We regularly see businesses that selected the debits option without configuring the mention on their invoices, or that apply the payments regime while forgetting to handle advances. Yet an advance makes VAT chargeable on collection, whatever option has been chosen.

Another blind spot is deduction on the client side. If you are on payments and your client deducts the VAT on receipt of your invoice without waiting to pay, they expose themselves to a reassessment. The rule is clear: the client deducts VAT when it becomes chargeable on the supplier's side.

Once the regime is chosen, a few points deserve regular checking. A well-configured invoicing and accounting tool avoids most discrepancies. Our comparison of the total cost of accounting software for SMEs and our digital finance transformation offer cover these settings.

• Check the consistency between the declared option and the software configuration.
• Make sure the wording VAT accounted for on debits prints automatically if you are on debits.
• Handle advances separately: they trigger VAT on collection in every case.
• Match invoices and payments if you are on payments, to attach the VAT to the right period.
• Distinguish goods flows from services flows where your activity combines both.

Several situations fall outside the standard pattern and deserve specific attention.

• Mixed activity of goods and services. Each flow follows its own chargeability rule. The sale of goods stays on delivery (and the advance since 2023), the service follows the services regime. A single invoice can therefore mix two moments of chargeability.
• Advances on services. Even under the payments regime, an advance collected makes VAT chargeable as soon as it is received. The debits option does not change this precedence of the advance.
• B2B relationships sensitive to deduction. If your client needs to deduct quickly, the debits option with the mention on the invoice lets them deduct from the invoice rather than at payment.
• Tight cash flow. For an activity with long payment terms, staying on payments avoids advancing VAT on amounts not yet received.
