Electronic Invoicing Timeline in Luxembourg: What Are the Key Deadlines for Businesses?
B2G Electronic Invoicing in Luxembourg: An Obligation Already in Force
Luxembourg has been advancing its transition to electronic invoicing for several years.
Since 2019, Luxembourg public authorities (government bodies, state administrations and departments, public institutions, local authorities, etc.) have been required to accept electronic invoices.
The Law of 13 December 2021, complemented by the Grand-Ducal Regulation of the same date, subsequently introduced the obligation for economic operators to submit their invoices electronically to the Luxembourg State and its public institutions.
This first phase has fostered the adoption of electronic invoicing in Business-to-Government (B2G) transactions and laid the groundwork for its forthcoming extension to Business-to-Business (B2B) exchanges.

B2B Electronic Invoicing in Luxembourg: A Requirement Planned from 2028
As part of the European ViDA (VAT in the Digital Age) reform, the European Union plans to generalize electronic invoicing, particularly for cross-border transactions, starting in 2030.
Like other Member States such as France and Belgium, Luxembourg intends to anticipate this transition by introducing a national mandatory electronic invoicing framework for domestic B2B transactions.
On 17 July, the Luxembourg Government Council approved a draft bill to extend the electronic invoicing requirement to domestic B2B transactions between businesses established in Luxembourg from 2028, subject to its adoption by the Chamber of Deputies.
B2B Electronic Invoicing Timeline in Luxembourg (2028–2029)
According to the information provided by the Luxembourg Chamber of Commerce, the electronic invoicing requirement would be gradually extended to Luxembourg companies based on their category.

Therefore, all Luxembourg companies should be able to receive electronic invoices from 1 January 2028.
The mandatory issuance of invoices in electronic format would be introduced progressively between 2028 and 2029, depending on the size of the company.
Electronic Invoicing in Luxembourg: Preparing for Compliance
The reform does not only concern the invoice format. Companies will also need to verify that their tools are compatible with the technical requirements associated with electronic invoicing.
The main areas requiring attention include:
- the ability of invoicing and accounting software to generate and receive invoices in a structured format;
- compatibility with the Peppol network, which is used as a secure exchange infrastructure for electronic invoices;
- the integration of tax data into ERP and accounting systems;
- the proper automation of applicable VAT rules.
The transition to electronic invoicing therefore requires a comprehensive approach combining tax compliance, information systems, and financial processes.
How to Prepare Your Business for Electronic Invoicing in Luxembourg?
To anticipate the 2028–2029 deadlines, Luxembourg companies should start implementing a structured preparation process now.
The main steps are as follows:

Review the VAT settings of ERP and accounting systems
1 - Monitor Electronic Invoicing Regulations
Luxembourg and European regulations are evolving rapidly. Companies must monitor upcoming legislative developments in order to accurately identify the obligations that apply to their specific situation.
To support businesses, VAT Solutions monitors new regulations and specific requirements related to electronic invoicing and VAT.
2 - Determine the Timeline Applicable to Your Company
Once the legislation is adopted, it will be essential to identify the relevant deadlines:
- Domestic B2B electronic invoicing in Luxembourg: 2028–2029;
- Electronic invoicing under the ViDA framework: from 2030 onwards.
This distinction will enable companies to adapt their transformation roadmap according to the transactions concerned.
3- Check the Compatibility of Systems with Electronic Formats and Peppol
Companies will need to assess their existing software solutions:
- ERP systems;
- invoicing tools;
- accounting software;
- electronic document management solutions.
The objective is to verify their ability to handle the required structured formats and exchanges through the appropriate networks.
4- Map Invoicing Flows and VAT Mapping
Before implementing any technical changes, a thorough analysis of invoicing flows is essential:
- types of transactions carried out;
- countries involved;
- customer/supplier profiles;
- VAT rules applied;
- mandatory information required on invoices.
This mapping also makes it possible to accurately identify the transactions affected by the 2028–2029 Luxembourg electronic invoicing requirements and those falling within the scope of ViDA from 2030 onwards. It also helps identify the flows that will be impacted by other ViDA developments starting in 2028.
5- Review the VAT Settings of ERP and Accounting Systems
The reform also requires companies to secure the tax rules integrated into their systems.
Companies will need to verify in particular:
- the VAT rates applied;
- the exemptions applied;
- transactions subject to the reverse charge mechanism;
- intra-community transactions;
- specific rules related to different types of operations.
Electronic Invoicing and VAT Compliance: A Strategic Challenge for System Configuration
The implementation of electronic invoicing in Luxembourg should be considered both a VAT compliance project and an IT project.
Electronic invoices are based on structured data that must accurately reflect the applicable tax treatment for each transaction. The quality of the configuration of ERP systems, invoicing software, and accounting systems therefore becomes a key element in securing companies’ VAT obligations.
Before deploying the reform, companies will need to ensure that their invoicing flows are properly identified and that the associated VAT rules are correctly integrated into their systems: applicable rates, exemptions, reverse charge mechanisms, intra-community transactions, mandatory invoice information, or specific rules related to different types of transactions.
A VAT mapping of flows is therefore a key step to obtain a comprehensive view of the transactions carried out and to verify the consistency between expected tax treatments and the data generated by the systems.
The success of the transition to electronic invoicing will therefore not depend solely on the technical ability to issue or receive invoices in the required format. It will also rely on the reliability of the VAT data integrated into management systems.
An early review of ERP configuration, customer and supplier data (“master data”), as well as embedded tax rules, will enable Luxembourg companies to secure their VAT compliance and prevent configuration errors from causing future anomalies in their invoicing processes or reporting obligations.
As an added benefit, operational companies will also be able to identify which of their flows are impacted by the new ViDA rules that will apply from 2028 onwards.
