E-invoicing was only the beginning: Belgium plans near-real-time VAT reporting from 2028

Oct 30

On 27 October 2026, the federal government submitted a draft law providing for the introduction of mandatory electronic VAT reporting from 1 January 2028. Businesses will have to provide certain invoice data to the VAT authorities almost immediately. In return, the annual client listing will be abolished for most taxable persons concerned.


The new rules build on the mandatory electronic B2B invoicing requirements in force since 1 January 2026. Whereas businesses currently exchange structured electronic invoices, from 2028 (most of) the data contained in those invoices will also be systematically reported to the Belgian Federal Public Service Finance.


Notably, Belgium will also impose the reporting obligation in certain cases where there is no obligation to issue a structured electronic invoice. This applies, among other things, to Belgian suppliers carrying out domestic transactions for foreign businesses holding a Belgian VAT number. The Council of State has expressly questioned whether this extension is compatible with EU VAT law, but the government has not followed that criticism.


To this end, the draft law replaces the current Article 53quinquies of the Belgian VAT Code, which governs the annual client listing, with a new electronic reporting obligation.

Dual-sided reporting via Peppol

The draft law provides for a dual-sided reporting obligation. Both the supplier of goods or services and the customer will have to transmit the relevant invoice data (new Article 53quinquies, §§ 1 and 2 of the Belgian VAT Code).


Reporting must take place within a maximum of five calendar days, except in cases of force majeure determined by the King. The specific deadlines will be laid down by Royal Decree. Data will be exchanged via the Peppol network (new Article 53quinquies, § 4 of the Belgian VAT Code).

The obligation mainly covers domestic B2B transactions that are not exempt under Article 44 of the Belgian VAT Code and for which a structured electronic invoice must be issued.


Intra-Community transactions fall outside this national scheme. For those transactions, the European ViDA Directive provides for a separate reporting system from 1 July 2030, which will replace the current intra-Community sales listing (Article 53sexies of the Belgian VAT Code and Article 5 of Directive (EU) 2025/516).


Corrective documents, including credit notes, will also have to be reported. Reporting is based on the invoice as issued and received, i.e. before the customer has reviewed its substance. Errors are corrected by means of a corrective document, which must in turn be reported.


Which invoice data will be reported?


The definitive list of data to be reported will be established by Royal Decree. Reporting may cover only data that the VAT rules require to be included on the structured electronic invoice or an equivalent document.


According to the explanation provided by the government's representative to the Council of State, the data referred to in Article 5, § 1, 1° and 5° to 11°, of Royal Decree No. 1 would be reported, together with the VAT identification numbers of the supplier and customer. These include, among other things, the invoice date and invoice number, the nature of the transaction, the taxable amount, the VAT rate and the VAT due (opinion No. 79.900/3, footnote 2).


The names and addresses of the supplier and customer are not included in this preliminary selection, although they are mandatory invoice particulars. Whether they will ultimately remain outside the reporting requirement will have to be clarified by the implementing Royal Decree.


That Royal Decree will also determine the specific reporting deadlines and technical arrangements. The law itself provides for transmission via the Peppol network (new Article 53quinquies, § 4 of the Belgian VAT Code). According to the explanatory memorandum, there will be no separate application or API provided by the Belgian Federal Public Service Finance.


Annual client listing abolished, but not for everyone


The annual client listing will be abolished for taxable persons subject to the new mandatory electronic reporting requirements.


However, the existing obligation remains in place for transactions carried out in 2027: that client listing must still be submitted by 31 March 2028 at the latest.


An important exception applies to taxable persons not established in Belgium who hold a Belgian VAT number. From 2028, they will not be required to electronically report their outgoing transactions.


For these foreign taxable persons, the annual client listing will, in principle, remain in place for transactions carried out up to and including 30 June 2030. They may, however, opt to electronically report all transactions concerned under their Belgian VAT number. In that case, the annual client listing requirement will cease to apply to those transactions (new Article 53quinquies, § 5 of the Belgian VAT Code).


Notably: reporting required even without mandatory e-invoicing


Belgian suppliers will therefore also have to report electronically when carrying out domestic transactions for foreign businesses holding a Belgian VAT number, even though those transactions are not subject to mandatory structured e-invoicing.


For example, a Belgian supplier delivering goods in Belgium to a Dutch business holding a Belgian VAT number will have to report the invoice data. The foreign customer is not subject to that obligation. Reporting is therefore one-sided (new Article 53quinquies, § 1, second paragraph, of the Belgian VAT Code).


In its opinion No. 79.900/3, the Council of State questions the compatibility of this extension with Article 273 of the VAT Directive. It recommends, pending the ViDA rules from 1 July 2030, limiting reporting to cases in which it follows on from electronic invoicing, or seeking an EU authorisation under Article 395 of the VAT Directive for the remaining cases.


The government has not followed this advice. In its view, Article 273 permits a separate reporting obligation, provided it does not impose any additional invoicing obligation, without the need for an EU authorisation.


The legal basis under EU law therefore remains a matter of debate.


Intra-group transactions within VAT units also covered


The draft law also contains specific provisions for VAT units.


The reporting obligation legally rests with the individual members of the VAT unit. It applies not only to the relevant outgoing and incoming transactions with third parties, but also to goods and services supplied between members for which a special document must be issued in accordance with Article 53, § 3, third paragraph, of the Belgian VAT Code.


From annual totals to individual invoices


The new reporting system will significantly change the information available to the VAT authorities.


Instead of annual totals per customer, the authorities will receive invoice-level data shortly after the invoice has been issued or received. The current administrative tolerances applicable to the annual client listing, including the tolerance for transactions of up to EUR 250, will not be carried over to the new reporting system.


Periodic VAT returns will, however, remain in place. Electronic reporting does not contain all the information needed to determine the VAT due and the right to deduct VAT.


Less administration, more scrutiny


The annual client listing will disappear for most businesses, but in return the VAT authorities will gain much faster and more detailed insight into their transactions. Dual-sided reporting will allow them to compare invoice data from suppliers and customers almost immediately, without waiting for VAT returns.


It will therefore be important to report the correct data. An incorrect VAT number, an incorrect VAT treatment or an incorrectly processed credit note may raise questions more quickly than before. According to the explanatory memorandum, a discrepancy between the two reports does not, in itself, constitute evidence of an irregularity. An adjustment will never follow automatically, but only after an assessment by a competent official.


Another challenge is undoubtedly the professional secrecy and duty of discretion applicable to certain professional groups. It will be necessary to examine which data are (automatically) transmitted to the tax authorities and which are not strictly necessary from a VAT perspective.


What does this mean for businesses?


Preparing for electronic VAT reporting involves more than a technical adjustment. Businesses will have to determine which transactions fall within the reporting obligation and how the correct VAT data are processed in their systems. Credit notes, transactions within VAT units and transactions with foreign customers, among others, will require particular attention.


1 January 2028 is fast approaching. The draft law still has to be adopted by the Chamber of Representatives. The specific data to be reported, deadlines and technical arrangements still have to be laid down by Royal Decree. Given the preparation time businesses need, it is high time these implementing rules were made available.
