Luxembourg - E-invoicing from 2028 onwards: what are the implications for Luxembourg’s financial sector?

B2B e-invoicing in Luxembourg from 2028, cross-border e-invoicing and digital reporting (DRR) under the ViDA reform: what impacts and challenges for the financial sector?

Banks, asset management companies, AIFMs, PSFs and other financial sector players:

The VAT exemption applicable to a large part of your activities might suggest that e-invoicing and the ViDA reform have little impact on your business. That would be a somewhat hasty conclusion.

Luxembourg has indeed taken an important step towards the digitalisation of VAT: Bill No. 8815, submitted on 30 July 2026, provides for the gradual rollout of mandatory business-to-business e-invoicing from 2028 onwards.

This Luxembourg reform will precede by two years the entry into force, on 1 July 2030, of the main new European rules on e-invoicing and Digital Reporting Requirements (DRR) introduced under the VAT in the Digital Age (ViDA) reform.

For financial sector professionals, the issue is therefore no longer a distant one. Preparation needs to start now.

ViDA: a major transformation of the EU VAT system

Adopted on 11 March 2025, the ViDA Directive brings significant changes to the EU VAT system. It is built around three main pillars: e-invoicing and digital reporting, the expansion of the One Stop Shop mechanisms to reduce the need for multiple VAT registrations, and new rules for platforms, particularly in the accommodation and transport sectors.

While the latter two pillars are less directly relevant to most financial sector professionals, the first will have very practical implications for their invoicing and accounting processes.

From 1 July 2030, structured e-invoicing will become the standard for transactions subject to the new intra-EU reporting requirements. A simple PDF sent by email will not qualify as an e-invoice under these new rules: the data will need to be issued, transmitted and received in a structured format that enables automated processing.

For affected cross-border transactions, invoices will also have to be issued no later than ten days after the taxable event. Additional data will be required, including the sequential number of the original invoice in the case of a corrective invoice, as well as the payment account details or identifiers of the account to which the supplier can be paid.

In Luxembourg, the change to mandatory B2B e-invoicing will start as early as 2028.

For Luxembourg businesses, there is no need to wait until 2030.

Bill No. 8815 provides for the rollout of domestic B2B e-invoicing in Luxembourg. Traditional invoices and simple PDF invoices will gradually be replaced, for transactions within the scope of the reform, by structured e-invoices that can be processed automatically.

The rollout will be gradual: from 2028, businesses will be required to be able to receive and process these invoices. The obligation to issue e-invoices will apply by 1 July 2028 at the latest to large businesses within scope, and by 1 January 2029 to other businesses within scope.

There are therefore two key deadlines to keep in mind:

2028: e-invoicing in Luxembourg.
2030: e-invoicing and digital reporting for intra-EU transactions covered by ViDA.

“Our financial services are VAT-exempt: are we really affected by e-invoicing and ViDA?”

This is, of course, a key question for the financial sector.

ViDA does not remove the option provided for under the VAT Directive to exempt certain VAT-exempt financial services from invoicing requirements. Financial sector professionals will therefore likely be able to choose not to issue invoices for eligible services and, as a result, avoid the obligation to issue e-invoices.

However, concluding that a bank, asset management company or AIFM can simply ignore the issue would be a mistake. The same entity may provide both VAT-exempt and taxable services. It may also carry out both domestic and cross-border transactions.

Take the example of a Luxembourg asset management company or AIFM. Depending on its business model, it may provide or receive management, risk management, distribution, advisory, administration, IT or intra-group services.

The VAT treatment of these flows can vary significantly: exemption, taxation, reverse charge or transactions outside the scope of Luxembourg VAT.

Some taxable services provided to taxable customers established in other EU Member States will fall within the new ViDA framework. Other domestic transactions may fall within the Luxembourg regime as early as 2028.

The first step is therefore to identify precisely which transactions are affected.

Even entities that do not charge VAT will need to prepare

This is probably the most important point for the financial sector.

The impact of the reform should not be assessed solely from the perspective of invoices issued.

A financial entity that carries out exclusively, or almost exclusively, VAT-exempt transactions will still purchase services from numerous suppliers: consultants, lawyers, accountants, IT providers, administrative service providers, landlords, and others.

It will therefore need to be able to receive and process structured e-invoices from its suppliers when these fall within the scope of the new requirements.

For some financial organisations, the main challenge may therefore lie on the procurement side rather than the sales side.

VAT data quality becomes critical

This development is particularly important in a sector where the VAT treatment of transactions can be complex.

Even today, certain corrections or classifications may be made at a later stage: when an invoice is recorded, when preparing the VAT return, or as part of a periodic review.

E-invoicing and digital reporting will gradually shift this analysis upstream.

To automate the processing of a transaction correctly, systems must have access to the information needed to determine its VAT treatment.

For example, businesses must be able to correctly identify the nature of the service, the status and location of the customer or supplier, whether an exemption applies, whether the reverse charge mechanism is applicable and, on the purchasing side, the rules governing VAT recovery.

Digitalisation can automate processes. But incorrect configuration can also automate errors.

Preparation for e-invoicing should therefore not start with choosing software. It should start with a mapping of transaction flows and their VAT treatment.

For a financial sector business, this analysis may cover, in particular:

the different categories of services provided and received;
VAT-exempt and taxable services;
domestic and cross-border transactions;
services received from foreign suppliers subject to the reverse charge mechanism;
self-billing arrangements;
VAT recovery rules;
available customer and supplier data;
VAT codes used in accounting systems;
current processes for issuing, receiving, validating and recording invoices and credit notes.

The objective is to establish a consistent link between the underlying transaction, its VAT treatment and how it is reflected in the IT system.

To take VAT return automation even further, this is also an opportunity to implement VAT codes tailored to the company’s activities and its right to deduct VAT, thereby avoiding time-consuming manual adjustments.

2028 Is Just Around the Corner: Preparing for Luxembourg E-Invoicing

For a financial organisation with multiple systems, complex approval processes, outsourced activities or a high volume of supplier invoices, compliance will involve much more than simply connecting an e-invoicing solution a few months before the deadline.

Businesses will need to identify the transactions concerned, check data quality, define the applicable VAT rules, adapt processes, configure systems and then test how they operate.

ERP, accounting and digitalisation projects currently underway should therefore already take the 2028 and 2030 deadlines into account.

Are you ready for e-invoicing, ViDA and VAT digitalisation ?

A few questions can already help assess the work ahead:

Have you mapped your incoming and outgoing invoicing flows?
Have you identified your VAT-exempt and taxable services and determined how they will be treated under the e-invoicing requirements?
Do you know how your systems will receive and process e-invoices from your suppliers?
Do the data currently available allow the correct VAT treatment to be assigned automatically to each transaction?
Have you identified the cross-border transactions that will be subject to the new ViDA requirements from 2030 onwards?

If some of the answers are still no, 2026 is the right time to start preparing.

VAT Solutions can support you with e-invoicing and VAT compliance

Preparing for e-invoicing is not simply an IT project. Before translating VAT rules into system requirements, it is first necessary to determine which rules apply to each transaction flow.

VAT Solutions supports financial sector professionals in mapping their transaction flows, determining the VAT treatment of their transactions, identifying transactions subject to e-invoicing requirements, reviewing VAT data and codes, and translating tax rules into functional requirements for their systems.

E-invoicing is coming to Luxembourg as early as 2028. Now is the time to turn a regulatory requirement into a well-managed project.
