OSS/IOSS 2026: what changes for your e-commerce with the correction to the European VAT regulation

Key data

E-commerce companies operating in multiple EU countries under the OSS (One Stop Shop) and IOSS (Import One Stop Shop) one-stop-shop schemes must pay attention to this technical amendment to Regulation (EU) 2017/2454, published on 12 August 2026 with immediate entry into force.

The correction, identified as CELEX:32017R2454R(03), does not introduce new obligations from scratch, but does correct textual errors that affected the correct interpretation of cooperation procedures between tax administrations of member states. In practice, this means that the legal texts governing how VAT information and money flows between countries are now unambiguous.

What does this regulation establish?

The amendment corrects textual errors in six specific articles of Regulation (EU) 2017/2454, all relating to the operation of special one-stop-shop schemes for e-commerce:

The three thematic blocks affected are:

• Electronic transmission of information: how the identification member state (where the company is registered in OSS/IOSS) transmits sales data to each consumption member state (where the buyer is located).
• Deadlines for transfer of VAT payments: when and under what conditions the identification member state transfers to the consumption member state the portion of VAT that corresponds to it.
• Notification of tax rates: how tax administrations communicate the VAT rates applicable in each country, critical data for the company to correctly calculate the tax on each sale.

Economic and operational impact

This correction does not modify VAT rates or registration thresholds. Its impact is operational and compliance-related: it ensures that the rules of the game between tax administrations are written without ambiguity, which has direct consequences for companies in three areas:

• Reconciliation of OSS/IOSS declarations: if the procedures for transmitting information between member states were being interpreted incorrectly by any administration, the correction may generate requests or reviews of past declarations.
• Cash management: the deadlines for transfer of VAT payments between member states directly affect when each country receives "its" portion of VAT. An incorrect interpretation may have generated discrepancies between what was declared and what was transferred.
• VAT calculation by country: the correct notification of tax rates between administrations is the basis on which the company calculates VAT on each transaction. Errors here translate into incorrect declarations.

Who does it affect?

• E-commerce companies with sales to end consumers in several EU countries registered in the OSS scheme (intra-community sales of goods and digital services).
• Companies registered in the IOSS scheme for importation of low-value goods (up to €150) from outside the EU.
• Marketplaces and digital platforms that facilitate cross-border sales and assume VAT responsibility under OSS/IOSS.
• Tax advisors and international VAT consultants who manage OSS/IOSS declarations for their clients.
• Finance and tax departments of business groups with online sales operations in the EU.

Practical example

A Spanish online clothing sales company registered in the OSS scheme through the Spanish Tax Agency (identification member state: Spain) sells to consumers in Germany, France and Italy (consumption member states).

Each quarter, the company files a single OSS declaration in Spain with VAT broken down by destination country. The AEAT, as the identification member state, has the obligation to electronically transmit that information to the German, French and Italian tax administrations, and to transfer them the corresponding VAT amounts within the deadlines established in articles 47e and 47f.

The correction to Regulation 2017/2454 ensures that articles 47b to 47g that regulate exactly that flow of information and money are written without textual errors. For the Spanish company, this means that the rules governing how the AEAT manages its OSS declaration with the rest of the administrations are now without interpretive ambiguity, reducing the risk of discrepancies between what was declared and what each consumption country expects to receive.

What should companies do now?

1. Review the corrected text of articles 47b to 47g of Regulation (EU) 2017/2454 to identify whether any of the textual corrections affect the interpretation that your company or your advisor has been applying.
2. Verify internal OSS/IOSS declaration procedures: check that the data transmitted to the identification member state (in Spain, the AEAT) is complete and complies with the electronic transmission procedures clarified in articles 47b, 47c and 47d.
3. Review the management of tax rates by country: confirm that your invoicing system or ERP correctly applies the VAT rates of each consumption member state, in accordance with the notification regulated in article 47g.
4. Consult with a tax advisor specialized in international VAT if there is any doubt about whether the textual corrections modify any specific obligation in OSS/IOSS declarations already filed or pending.
5. Document the review: keep internal record that the impact of this correction has been analyzed, especially if the company has had requests or discrepancies with any EU tax administration in recent years.
