2026 e-commerce VAT is about reconciliation. A marketplace may sell, collect, deduct commission, handle a return and apply different VAT logic depending on the country. Management must rebuild the gross flow before looking at the net payout.
Executive Summary#
OSS, IOSS, marketplaces and PSPs must be controlled together. This article targets e-commerce businesses selling beyond their own store and wanting to avoid accounts built on incomplete exports.
Field Diagnostic#
| Situation | Risk | Evidence or control |
|---|---|---|
| EU sale | customer country misidentified | address, VAT country, OSS regime |
| Low-value import | IOSS not reconciled | return, transport, marketplace |
| Customer return | credit note not linked | original order, refund, inventory |
Documents and Evidence to Gather#
- order exports by country
- gross/net PSP report
- marketplace report
- OSS-IOSS register
- returns and credit-note tracking
Personalised Operating Method#
The review should start with EU sale, because the identified risk is clear: customer country misidentified. The evidence to produce is not a general comment but a verifiable item: address, VAT country, OSS regime. This first level prevents management from building a decision on commercial impressions or an overly aggregated accounting total.
The second point is Low-value import. Here, the risk is different: IOSS not reconciled. Management should therefore organise the file around return, transport, marketplace, then check that this evidence appears in accounts, cash and monthly reporting.
Finally, Customer return must be isolated before closing. When credit note not linked, management becomes fragile. The expected evidence, original order, refund, inventory, turns a grey area into a documented decision.
Documentary Reading#
The most useful documents in this file are: order exports by country, gross/net PSP report, marketplace report, OSS-IOSS register, returns and credit-note tracking. They should not only be archived; they should be reconciled with one another. An invoice without payment, a contract without flows, an export without bank matching or a decision without minutes is not enough to secure the position.
Leadership Arbitration#
Management should mainly retain three decisions: choose the master source for orders, reconcile refunds and credit notes, separate own-store and marketplace sales. These decisions give the firm a concrete roadmap and keep the topic from remaining an abstract recommendation.
Sector Case Study#
A D2C brand sells on Shopify, Amazon and TikTok Shop. Apparent revenue grows, but refunds and commissions grow faster than sales. Without order-level reconciliation, VAT may look correct in total and still be wrong by country or channel.
Our Chartered Accountant's View#
Hayot Expertise rebuilds the order-payment-VAT tunnel before automating. The priority is knowing whether each euro comes from own-store sale, marketplace sale, refund or correction.
The Underestimated Risk#
The underestimated risk is the marketplace deemed supplier rule. Depending on the case, it can change who is deemed to sell to the customer and therefore the VAT reading of the flow.
What Leadership Must Decide#
- choose the master source for orders
- reconcile refunds and credit notes
- separate own-store and marketplace sales
- document OSS-IOSS by country
2026 Watchpoints#
- review marketplace reports
- do not confuse PSP payout and revenue
- test delivery-country changes
- prepare B2C e-reporting

Frequently asked questions
e-commerce VAT France: when should the treatment be secured?+
Secure it before invoicing or receipt, not only when filing. Nature of flow, customer, country and evidence must be known upstream.
What does e-invoicing change for an e-commerce business?+
It requires more reliable invoice data and audit trail. From 1 September 2026, receiving e-invoices becomes an immediate readiness topic for companies in scope.
What is the trap of net bank receipts?+
Net receipts can hide commissions, fees, credit notes, refunds, third-party funds or taxable bases. VAT must start from the qualified gross flow.
Should exempt or reverse-charge cases be documented?+
Yes. A non-taxed flow is not a flow without evidence. Keep legal basis, invoice or contract and accounting reconciliation.
When should VAT be reviewed?+
Before a new sales channel, platform, international flow, invoicing change or atypical service.
