Which countries currently require mandatory eInvoicing?

Italy and Turkey already require mandatory eInvoicing, and several other countries have since introduced or confirmed their own mandates. Belgium made B2B eInvoicing via Peppol mandatory from 1 January 2026, Poland's KSeF system became mandatory from 1 February 2026 for the largest taxpayers and 1 April 2026 for most other businesses, and France requires all businesses to be able to receive eInvoices from 1 September 2026.

What eInvoicing models do countries use to enforce VAT mandates?

Countries generally use one of four models: real-time reporting, where invoice data is sent to tax authorities as soon as it is issued, clearance models, where invoices need government approval before being sent to customers, centralised exchange models, where all invoices pass through a government-run platform, and decentralised CTC and exchange models, such as Peppol, where multiple providers handle transactions while still relaying data to tax authorities.

What is the UK's timeline for a mandatory eInvoicing requirement?

The UK government published its implementation roadmap on 28 October 2026, and the UK is expected to introduce a mandatory eInvoicing requirement from April 2029, based on the Peppol four-corner model. Businesses trading with the UK should start preparing systems and processes well ahead of that date to avoid a late rush to comply.

What business benefits come from adopting government-mandated eInvoicing?

Adopting mandated eInvoicing brings faster, more accurate transactions with fewer errors and greater transparency, along with easier management of cross-border invoicing through a consistent digital approach. Over time it also reduces reliance on manual handling, printing and mailing, which lowers administrative costs and helps strengthen financial control and cash flow.

VAT Mandates

VAT mandates are rapidly being implemented by governments, globally. But what are they, and what do they mean for your business?

Transalis8 November 2024Updated 7 October 2026

Key takeaways

Governments worldwide are introducing VAT mandates that require businesses to send and receive invoices in an approved digital format, aiming to increase transparency and close the VAT gap.
Countries take different approaches to VAT mandates, using real-time reporting, pre-clearance approval, centralised government exchanges, or decentralised networks such as Peppol.
Businesses that fail to meet eInvoicing standards risk penalties, payment delays and damaged trading relationships, so understanding the model each country uses is essential.
Moving to mandated eInvoicing streamlines payment processing, speeds up transactions, reduces errors and increases transparency, while also simplifying cross-border invoicing with a consistent digital approach.
Over time these efficiency gains can strengthen financial control and cash flow, alongside reduced reliance on manual invoice handling, printing and mailing.

What is a government VAT mandate for eInvoicing?

A VAT mandate is a legal requirement for businesses to send and receive invoices in a digital format approved by their country's tax authority, instead of using paper or PDF invoices. The goal is to increase transparency, reduce tax evasion, and close the VAT gap, the difference between expected and actual VAT revenue collected.

Globally, tax authorities are aiming to close the VAT Gap by introducing VAT mandates for registered businesses.

Countries in South America have already seen impressive results with this strategy, and now, other countries are following their example.

If your business trades internationally, it’s likely these mandates will soon impact you, if they haven’t already. Whether you’re new to VAT mandates or already familiar with them, this post provides insights and updates designed to help you stay informed.

What are government-mandated eInvoicing requirements?

Let’s start with the basics.

Government-mandated eInvoicing refers to the legal requirement that companies must send and receive invoices in a digital format, specifically approved by a country’s tax authority.

The goal is to increase transparency, reduce tax evasion, and close the VAT gap (the difference between expected and actual VAT revenue collected).

In Europe, countries like Italy and Turkey already have these requirements in place, while others are set to join soon. For instance, France, Belgium and Poland have announced plans to mandate eInvoicing by 2026. The UK is also expected to start consultation as early as Spring 2025.*

The transition to mandated eInvoicing means that businesses will need to shift from paper or PDF invoices to either a fully electronic or a hybrid model of PDF and electronic, according to local government regulations.

Failing to meet these standards can result in penalties, payment delays, and even lost business relationships.

How are VAT mandates implemented?

When it comes to VAT mandates, there isn’t a single, universal approach. Countries choose different models based on their specific needs and systems. Here’s a quick look at the main types:

Real-Time Reporting (RTR):
This model requires businesses to report invoice data to tax authorities in near-real-time. Tax authorities receive the data as soon as the invoice is issued, helping ensure transparency and rapid validation.
Clearance Models:
In this setup, invoices must be approved by a government entity before they can be sent to customers. This “pre-clearance” approach ensures tax authorities validate invoices right from the start.
Centralised Exchange Models:
Some countries operate a centralised digital exchange where all invoices are sent. In this system, invoices pass through a government-run platform, creating a single point for transaction monitoring.
Decentralised CTC and Exchange (DCTCE):
This model enables invoices to be exchanged through a decentralised network, such as Peppol. With DCTCE, multiple providers can handle transactions while still relaying necessary information to tax authorities. This approach allows for greater flexibility, letting businesses choose their provider for compliance while ensuring transparency and reporting requirements are met.

Understanding which model applies to each country you do business in is crucial. The requirements, timeline, and steps will vary depending on the region.

What are the benefits of VAT mandates for your business?

The idea of more government oversight may sound daunting, but mandated eInvoicing can actually bring a host of benefits to your business.

First, there’s the potential for significant cost savings. By moving to a digital process, businesses can reduce reliance on manual invoice handling, printing, and mailing, all leading to lower administrative costs.

Additionally, digital invoicing streamlines payment processing. Transactions become faster, errors drop, and transparency increases. Businesses may also find it easier to manage cross-border transactions by having a consistent, digital approach to invoices. Over time, these efficiency gains can strengthen financial control and improve your company’s cash flow.
