Luxembourg: The Council of Government Approved Two Further VAT Instruments on July 17, 2026 — a Separate Bill Transposing Article 2 of ViDA and a Draft Regulation Fixing the Common Delivery Network

Country Update — Luxembourg  |  11 August 2026  |  Topic: E-Invoicing / ViDA

The Luxembourg Council of Government’s session of July 17, 2026, is known for one thing: approval of the bill extending mandatory electronic invoicing to domestic business-to-business transactions.

It approved two further instruments the same day that have attracted almost no attention and that matter independently. The first is a draft Grand-Ducal Regulation fixing the common delivery network and the alternative technical solutions made available for electronic invoicing — the instrument that will carry the network designation, the technical parameters and the fallback arrangements.

The second is a separate bill amending the Luxembourg VAT Law to transpose Article 2 of Council Directive (EU) 2025/516, which is the platform economy and registration pillar of ViDA and not the electronic invoicing pillar. This is a backfill update on both.

Background

Luxembourg has required electronic invoicing in business-to-government transactions since 2021, phased by entity size, and that regime has operated through a designated common delivery network with a non-automated fallback for low-volume issuers.

The instrument that established it is the Grand-Ducal Regulation of December 13, 2021, which designated Peppol, operated by OpenPeppol, as the common delivery network for business-to-government invoicing, and which set two online forms on the government service portal as the non-automated fallback route.

That existing business-to-government framework requires conformity with EN 16931-1:2017 and one of two authorized syntaxes: XML UBL in accordance with ISO/IEC 19845:2015, or XML UN/CEFACT Cross Industry Invoice in accordance with the 16B SCRDM-CII schemas. Those parameters are the baseline against which the new domestic business-to-business regime will be built.

Council Directive (EU) 2025/516 of March 11, 2025 is structured in two operative articles for present purposes. Article 1 carries the electronic invoicing and digital reporting provisions. Article 2 carries the platform economy and single value added tax registration provisions, applying from January 1, 2027 in most member states.

Member states are transposing the two through separate instruments and on separate timetables, and Luxembourg has followed that pattern precisely — which is why two distinct bills emerged from the same Council session.

The instrument that has been widely reported is the bill transposing Article 1: it extends mandatory electronic invoicing to domestic business-to-business transactions, with reception obligations from January 1, 2028, and issuance obligations phased from July 1, 2028, for large and medium enterprises and January 1, 2029 for all others, built on a four-corner common delivery network with no domestic digital reporting requirement.

KGT has reported on that bill. The two instruments described here are separate and have not been covered.

The Legislative Change

Both instruments are legislative or regulatory in character, and both were approved by the Council of Government — the Cabinet — on July 17, 2026, and communicated through the government portal, with the communication page modified on July 18, 2026. Neither is yet in force and neither has a published effective date.

The first instrument is a draft Grand-Ducal Regulation fixing the common delivery network and the alternative technical solutions made available for electronic invoicing, taken in execution of the electronic invoicing bill approved at the same session.

Its stated purpose is to fix the framework of the common delivery network for issuing, transmitting and receiving electronic invoices, so that issuers and recipients are not forced to deploy separate, non-interoperable solutions.

That is the instrument that matters operationally, and its significance is easy to miss because it has no content yet. A bill that says invoices must travel over a common delivery network tells a business nothing it can implement.

The Grand-Ducal Regulation is where the network is actually designated, where identifiers and technical parameters are fixed, and where the alternative — manual or low-volume — solutions are defined together with any de minimis volume thresholds that condition their use. It is the direct analogue of the Grand-Ducal Regulation of December 13, 2021 for the business-to-government regime.

One caution on attribution is important here. The official communiqué does not name Peppol. Continuity with the 2021 business-to-government designation is a reasonable expectation and is what most commentary assumes, but it is an inference and not a confirmed fact. Until the Grand-Ducal Regulation is published, no organization should treat the designation of Peppol for domestic business-to-business invoicing in Luxembourg as settled.

The second instrument is a bill amending the amended Law of February 12, 1979, on value added tax with a view to transposing Article 2 of Directive (EU) 2025/516. This is distinct from the electronic invoicing bill, which transposes Article 1 of the same directive. It is therefore Luxembourg’s vehicle for the non-electronic-invoicing half of ViDA — the platform economy, deemed supplier and single registration provisions.

What can be reported about it is limited, and the limitation should be stated plainly: the official communiqué gives the title only. There is no scope, no threshold, no commencement date and no parliamentary dossier number in the official text. As at the date of this update the Chamber of Commerce opinions register listed bills 8811, 8813 and 8814 but not this one, and its deposit with the Chamber of Deputies could not be established.

In the same session the Council also approved a bill amending the Law of May 16, 2023 on automatic exchange of information reported by platform operators — the DAC7 regime. That is adjacent platform reporting but direct tax rather than value added tax, and it is noted here only for completeness.

Scope

The draft Grand-Ducal Regulation will apply to the population covered by the domestic business-to-business electronic invoicing regime it serves, and therefore ultimately to every taxable person in Luxembourg subject to that regime, on the phased timetable of the parent bill: reception from January 1, 2028, issuance from July 1, 2028 for large and medium enterprises and from January 1, 2029 for all others.

Its practical scope is narrower and more immediate than that, however, because it determines what a business has to build. Until the network and the authorized syntaxes are designated, no Luxembourg business-to-business implementation can be specified with confidence beyond what the existing business-to-government parameters suggest.

The alternative technical solutions provision is of particular scope interest to small issuers. In the business-to-government regime the fallback was a pair of online forms on the government service portal.

Whether the business-to-business alternative takes a comparable form, and whether it is conditioned on volume thresholds or on fees, is precisely what the Regulation will settle. Reports circulating in the market of a progressive per-invoice fee scale for alternative solutions are not confirmed in any official source and should not be relied on.

The Article 2 bill will apply from the dates the directive requires, which for most of Article 2 is January 1, 2027 — a date materially earlier than the electronic invoicing timetable. Its scope, on the directive, reaches platform operators facilitating supplies with Luxembourg exposure, businesses selling through such platforms, and businesses affected by the single registration and deemed supplier provisions.

The Luxembourg text will determine the national detail and is not yet available.

Businesses whose Luxembourg exposure is exclusively business-to-government are unaffected by both instruments in the immediate term, though the business-to-government framework is the template from which the business-to-business parameters are likely to be drawn.

Timeline

• December 13, 2021 — Grand-Ducal Regulation designating Peppol, operated by OpenPeppol, as the common delivery network for business-to-government electronic invoicing, with two government portal forms as the non-automated fallback.
• 2021 onward — business-to-government electronic invoicing phased in by entity size, requiring conformity with EN 16931-1:2017 and either XML UBL per ISO/IEC 19845:2015 or XML UN/CEFACT CII per the 16B SCRDM-CII schemas.
• March 11, 2025 — Council Directive (EU) 2025/516 adopted.
• July 17, 2026 — the Council of Government approves, in a single session: the bill extending mandatory electronic invoicing to domestic business-to-business transactions, transposing Article 1 of the directive; the draft Grand-Ducal Regulation fixing the common delivery network and the alternative technical solutions; a separate bill amending the Law of February 12, 1979 on value added tax to transpose Article 2 of the directive; and a bill amending the Law of May 16, 2023 on automatic exchange of information reported by platform operators.
• July 18, 2026 — the government communication page recording the session is modified.
• As at the date of this update — no Council of State opinion and no Chamber of Commerce opinion on the electronic invoicing bill had been published; the Article 2 bill did not appear on the Chamber of Commerce opinions register; and the draft Grand-Ducal Regulation had not been published in the Journal officiel.
• January 1, 2027 — the date from which most of Article 2 of the directive applies, and therefore the effective deadline for the second bill.
• January 1, 2028 — reception obligation under the domestic business-to-business electronic invoicing regime.
• July 1, 2028 — issuance obligation for large and medium enterprises.
• January 1, 2029 — issuance obligation for all other taxable persons.

Businesses Affected

Every taxable person in Luxembourg is ultimately affected by the draft Grand-Ducal Regulation, because it determines the technical means by which the domestic business-to-business obligation will be discharged. In the immediate term the businesses most affected are those scoping their Luxembourg implementation now, because the Regulation is the missing specification.

Groups planning a multi-country Peppol rollout are affected in a specific way. It would be natural to assume Luxembourg can be added to an existing Peppol footprint based on the 2021 business-to-government designation.

That assumption is probably correct and is not yet confirmed. A group making an architectural commitment on it should record the assumption explicitly and revisit it when the Regulation is published.

Small and low-volume Luxembourg issuers are affected by the alternative technical solutions provision, which will determine whether a manual route remains available to them and on what terms.

Platform operators and businesses selling through platforms with Luxembourg exposure are affected by the Article 2 bill, and on a materially earlier timetable than the electronic invoicing regime — January 1, 2027 rather than 2028 or 2029. This is the point most likely to be missed, because Luxembourg commentary has focused almost exclusively on the electronic invoicing bill and the two are easily conflated as one ViDA project.

Businesses affected by single value added tax registration and deemed supplier provisions across the European Union should treat Luxembourg as one of the member states now legislating for Article 2, alongside Italy and Croatia.

Platform operators within the DAC7 regime are affected by the fourth instrument approved at the same session, though that is a direct tax reporting matter.

Required Actions

• Separate your Luxembourg ViDA work into two workstreams: Article 1 electronic invoicing, on the 2028 to 2029 timetable, and Article 2 platform economy and registration, on the January 1, 2027 timetable. Treating them as one project will cause the earlier obligation to be planned to the later date.
• Do not assume Peppol is the designated common delivery network for domestic business-to-business invoicing in Luxembourg. It is a reasonable expectation given the 2021 business-to-government designation, and it is not confirmed in the official communiqué. Record the assumption and revisit it when the Grand-Ducal Regulation is published.
• Take the existing business-to-government parameters as your working specification in the meantime: EN 16931-1:2017 conformity, with either XML UBL per ISO/IEC 19845:2015 or XML UN/CEFACT CII per the 16B SCRDM-CII schemas. These are the most likely basis for the business-to-business regime.
• Where your organization relies on a manual or low-volume invoicing route in Luxembourg, monitor the alternative technical solutions provision of the Grand-Ducal Regulation specifically, including any volume threshold or fee that conditions its use. Do not rely on the per-invoice fee figures circulating in commentary, which are not officially confirmed.
• For Article 2, assess your Luxembourg platform and cross-border business-to-consumer exposure now, against the directive rather than the national text, since the national text is not yet available and the application date is January 1, 2027.
• Monitor the Chamber of Deputies dossier register and the Council of State opinions for both bills, and the Journal officiel for the Grand-Ducal Regulation. As at the date of this update none had produced a published document.
• Treat as unconfirmed the detailed figures circulating on the electronic invoicing bill — including size thresholds measured at a 2026 closing date, exclusion of unstructured formats, abolition of recipient consent, and the number of issuance waves, on which sources conflict between two and three. Verify against the deposited bill text before relying on any of them.
• If your organization is a platform operator, review the DAC7 amending bill separately, since it was approved in the same session and concerns the same commercial activity under a different regime.

Practical Implications

The useful insight here is structural rather than technical. Luxembourg produced four value added tax and platform instruments in a single Cabinet session, and public attention settled on one of them.

The three others include the instrument that will actually specify how Luxembourg electronic invoicing works, and a bill with an application date a full year earlier than the one everyone is planning for.

That is a fair description of how ViDA transposition is being received generally: the electronic invoicing pillar absorbs the professional attention, and the Article 2 pillar arrives first.

On the Grand-Ducal Regulation, the practical position is that Luxembourg has legislated the obligation before publishing the specification. That is not unusual — France did the same and closed the gap only weeks before go-live — but it has a consequence for planning.

A Luxembourg implementation cannot be finalized until the Regulation is published, and the timetable gives no clue as to when that will be. Organizations should build the analysis and the data readiness now, and defer the connectivity decision.

The absence of Peppol from the official communiqué is worth dwelling on briefly, because it is exactly the kind of detail that gets filled in by inference and then repeated as fact. Every commercial account of the Luxembourg bill describes a Peppol four-corner network.

The official text describes a common delivery network. The two are very likely the same thing, and it costs nothing to hold the distinction until the Regulation confirms it.

For the Article 2 bill, the honest position is that almost nothing can be said about the Luxembourg implementation, and that is itself the finding. A bill approved by Cabinet in July 2026, with an application date of January 1, 2027, of which only the title is published, leaves affected businesses roughly five months from publication to compliance in the best case.

Organizations with Luxembourg platform exposure should be working from the directive and not waiting for the national text.

Finally, the verification difficulty encountered on this topic is worth recording. The Chamber of Deputies dossier for the electronic invoicing bill could not be resolved, the Council of State and Chamber of Commerce had published no opinions, and the reported deposit of the bill at the end of July 2026 could not be confirmed against any primary source.

Where a Luxembourg position matters, the deposited bill text should be obtained directly rather than through summaries, several of which conflict on the number of issuance waves.

Expected Next Steps

The draft Grand-Ducal Regulation should be expected to be published in the Journal officiel, and that publication is the point at which the Luxembourg common delivery network, the authorized syntaxes and the alternative technical solutions become known. It is the single most important document outstanding for anyone implementing in Luxembourg.

Opinions from the Council of State and from the Chamber of Commerce should be expected on both bills, and both bodies have in the past produced substantive comment that has changed Luxembourg tax legislation.

The Article 2 bill should be expected to be deposited with the Chamber of Deputies and to receive a dossier number, at which point its scope, thresholds and commencement dates become readable. Given the January 1, 2027 application date, that should happen in the autumn of 2026.

Confirmation should be expected of whether the deposit of the electronic invoicing bill reported for the end of July 2026 in fact occurred, and of the definitive number of issuance waves, on which secondary sources conflict.

Guidance from the Luxembourg tax authorities on the domestic business-to-business regime should be expected once the Grand-Ducal Regulation is published, and would be the point at which practical questions such as identifier registration and status messaging are settled.

KGT will report separately on the publication of the Grand-Ducal Regulation, on the deposit and content of the Article 2 bill, and on the opinions of the Council of State and Chamber of Commerce on both instruments.

How Can KGT Support You?

KGT is a specialist indirect tax technology firm. Our SAP-integrated e-invoicing and e-reporting add-ons generate, validate and transmit country-compliant structured documents directly from SAP ECC and SAP S/4HANA, keeping tax determination, document mapping, status handling and the audit trail inside the system of record rather than in a downstream converter. Because the add-ons validate against the current national schemas, schematrons and code lists before transmission, a change of specification version becomes a configuration and regression-test exercise rather than a redesign.

We also deliver SAP Document and Reporting Compliance (DRC) services end to end: fit-gap assessment against the national mandate, activation and configuration of the relevant country versions, eDocument and eStatement setup, interface and connectivity design, master and transactional data remediation, test strategy including negative testing against the authority’s own validation artifacts, and post-go-live monitoring of rejections and status reconciliation. If you would like a readiness review against the developments described above, or an impact assessment for your SAP landscape, we would be glad to help.
