Event summary

Sovos is proud to sponsor and participate in the 77th IFA Congress, where global tax leaders gather to explore the future of international taxation. As part of the programme, Sovos will host a seminar titled “Mirror Visibility in Motion: A Vision for Global Tax Compliance”, led by Christiaan van der Valk. The session will offer a strategic look at regulatory shifts, showcase customer success stories, and highlight how Sovos Intelligence empowers smarter, faster compliance decisions in an AI-driven world.

Meeting Venue

Lisbon Congress Centre – CCL | Praça das Indústrias 1, 1300-307 Lisboa, Portugal

The IRS has confirmed the retirement of the long-standing FIRE system, ushering in a new era of information return filing through IRIS. After serving as the backbone of electronic tax reporting since the 1980s, this significant change will reshape how organizations approach information return filing.

Join Sovos tax experts for a deep dive into what this transition means for your business. We’ll break down the timeline, requirements, and risks while offering practical guidance to ensure a smooth move to IRIS.

Most finance and tax teams think they’ve got sales and use tax under control. Auditors know better.

In this webinar, we expose the hidden audit risk that’s catching even the most sophisticated companies off guard: use tax.

While sales tax automation gets all the attention, use tax compliance remains a patchwork of spreadsheets, siloed systems, and unvalidated assumptions – a goldmine for state auditors on the hunt for revenue.

The “One Big Beautiful Bill” (OBBB) represents one of the most sweeping shifts to the tax compliance landscape in recent history. With wide-ranging provisions that touch nearly every corner of information reporting and withholding (IRW), this legislation will fundamentally reshape how organizations manage compliance, reporting, and operational risk.

For tax leaders, the OBBB is more than just new rules—it’s a call to rethink long-standing processes and prepare for a transformed regulatory environment.

Slovenia E-invoicing

Slovenia is in the middle of its journey towards mandatory e-invoicing. It is already in place for B2G transactions, and the current plan is for B2B e-invoicing to be compulsory from 2027.

Learn more about Slovenia E-invoicing through this page, and be sure to bookmark it to keep up to date with future regulatory updates.

B2B e-invoicing in Slovenia

While there is no mandate for B2B e-invoicing, Slovenia’s tax authorities plan to introduce an obligation.

Currently, the plan is for e-invoicing for business-to-business transactions to become obligatory from 1 January 2027.

Should the obligation come into effect, businesses will need to be able to issue, receive and process e-invoices for transactions with other organisations. However, e-invoices cannot be sent via email.

This obligation will cover cross-border transactions, requiring businesses to issue e-invoices for exports and imports.

The plan is for e-invoices to be acceptable in the following formats:

  • e-SLOG national standard
  • EN 16931 EU standard
  • Internationally recognised formats agreed by both parties

The regulation will require issuers and recipients to forward e-invoices, in the e-SLOG format, to the tax authorities within eight days of issuance.

B2G e-invoicing in Slovenia

B2G e-invoicing is mandatory in Slovenia, meaning businesses that supply public authorities must issue electronic invoices. The Provision of Payment Services to Budget Users Act is responsible for the obligation.

E-invoices relating to business-to-government transactions must be processed through the Public Payments Administration (PPA) system – a step meant to guarantee integrity and integration in the public sector.

Slovenia has a national e-invoicing format, e-SLOG, which was updated to align with the European e-invoicing standard EN 16931.

There is a national registry of electronic invoicing recipients to provide transparency into exchanges, and the PPA incorporates eDelivery standards to ensure interoperability with European networks.

The use of Peppol in Slovenia

Like many European countries, Slovenia’s tax authorities utilises Peppol – the pan-European e-invoicing protocol, network and standard – for electronic invoices relating to cross-border transactions.

The Ministry of Finance and company ZZI d.o.o. are both Peppol Access Points and Service Metadata publishers in Slovenia. This means they enable the transmission of e-invoices for cross-border transactions in the country.

Find out more about Peppol e-invoicing.

Follow Slovenia’s e-invoicing journey below.

  • 1 January 2015: B2G e-invoicing becomes mandatory
  • 2018: The Public Payment Administration (PPA) integrates Peppol for cross-border e-invoicing
  • October 2020: The e-SLOG e-invoice format becomes mandatory for B2G e-invoices
  • 1 July 2024: Slovenia releases draft proposal for mandatory B2B e-invoicing
  • 11 February 2025: New draft law published regarding mandatory B2B e-invoicing
  • 1 January 2027: The proposed date for mandatory B2B e-invoicing to be implemented
  • 1 July 2030: Slovenian VAT-registered businesses must comply with VAT in the Digital Age (ViDA) requirements, which include mandatory e-invoicing and digital reporting for Intra-Community B2B transactions

Setting up e-invoicing in Slovenia with Sovos

With Slovenia’s B2B e-invoicing mandate on the way, your business must be prepared. Not to mention changes to regulations in other countries. If you have a multinational organisation, tax and e-invoicing compliance is likely a significant drain on time and resources.

Choosing a single vendor for all tax compliance, everywhere you do business, is the key to reclaim your time and peace of mind. Sovos can help.

FAQ

E-invoicing has been mandatory for B2G transactions in Slovenia since 2015. It will become mandatory for B2B transactions from 1 January 2027.

Once e-invoices are mandated for B2B transactions in 2027, electronic invoices must be formatted as e-SLOG, the European Standard, or other approved formats. This obligation will cover cross-border transactions, requiring businesses to issue e-invoices for exports and imports.

The proposed obligation will also require issuers and recipients to forward e-invoices in the e-SLOG format to the tax authorities within eight days of issuance.

For B2G e-invoicing in Slovenia, which is mandatory, e-invoices must be processed through the Public Payments Administration (PPA) system. Slovenia has a national e-invoicing format, e-SLOG, which was updated to align with the European e-invoicing standard EN 16931.

A national registry of electronic invoicing recipients provides transparency into exchanges, and the PPA incorporates eDelivery standards to ensure interoperability with European networks.

Belarus E-invoicing

While B2B and B2G e-invoicing has been mandatory since 2016, Belarus is still working towards implementing electronic invoicing across a variety of transactions.

Keep current on Belarus’ e-invoicing journey with this page. Be sure to add it to your bookmarks to learn about any developments.

B2G and B2B e-invoicing in Belarus

Issuing e-invoices has been mandatory for B2G and B2B transactions in Belarus since 2016. This came into force with the approval of the Law of the Republic of Belarus No. 343‑З, dated 30 December 2015, which amended the Belarus Tax Code.

There is a dedicated governmental portal for transmitting invoices electronically, and they must be in XML format.

Importantly, e-invoices must be validated by the Ministry of Taxes and Duties of the Republic of Belarus (NALOG) before they are sent to the recipient.

FAQ

Electronic invoicing is mandatory for B2G and B2G transactions in Belarus, facilitated by the government’s dedicated e-invoicing system.

Yes, the format of electronic invoices must be approved by the Ministry of Taxes and Dues of the Republic of Belarus.

Estonia E-invoicing

Estonia has been working on its electronic invoicing regulations for many years, mandating B2G e-invoicing since 2019. B2B is more complicated, however.

This page has all the information you need to understand Estonia’s e-invoicing rules, journey and nuances.

B2B e-invoicing in Estonia

B2B e-invoicing is not mandatory in Estonia.

However, starting July 2025, Estonian taxpayers will be required to issue e-invoices upon the buyer’s request. Suppliers will not be generally mandated to issue e-invoices, but buyers will have the right to request them if they fulfil a specific condition.

This mandate explicitly covers businesses that register themselves in the Commercial Register as e-invoicing receivers, meaning they are entitled to request e-invoices. This is known as “buyer’s choice”. The default format is the European Standard (EU EN16931), but the parties can agree on another relevant standard.

Suppliers of businesses are not specifically mandated to issue e-invoices, but they do have to comply with requests from e-invoicing receivers.

A blanket mandate for B2B e-invoicing is currently planned to roll out in 2027 in Estonia.

B2G e-invoicing in Estonia

E-invoicing has been mandatory for the public sector since March 2017, meaning that the contracting public authority must be able to receive e-invoices in B2G transactions.

As of 1 July 2019, it has become mandatory for all suppliers to submit machine-processable invoices (e-invoices) for B2G transactions.

As Estonia runs a decentralised system, public sector entities receive e-invoices through private service providers. Roaming agreements and Peppol connectivity ensure interoperability between service providers.

The use of Peppol in Estonia

Estonia uses two primary e-invoicing formats: its national standard and the standardised Peppol format.

The country utilises Peppol’s network and framework much less than many other European countries. Traditionally, the pan-European initiative is utilised to ease the complexity of cross-border trading and e-invoice transmission.

Peppol is an international, EU-born protocol and framework that aims to simplify cross-border and governmental trade. While its adoption is widespread across Europe, it also standardises trading in countries such as Australia and Singapore.

Find out more about Peppol e-invoicing.

Timeline of e-invoicing adoption in Estonia

Here are the key dates in Estonia’s e-invoicing journey.

  • 1 July 2019: B2G e-invoicing becomes mandatory for all suppliers
  • 1 July 2025: The buyer is entitled to request issuance of an electronic invoice for goods or services purchased in B2B transactions
  • 2027: Estonia plans to enforce mandatory e-invoicing for all businesses
  • 1 July 2030: Estonian VAT-registered businesses must comply with VAT in the Digital Age (ViDA) requirements, which include mandatory e-invoicing and digital reporting for Intra-Community B2B transactions

Setting up e-invoicing in Estonia

E-invoicing is not fully mandated in Estonia just yet, meaning businesses trading in the country will have to continue adapting for the foreseeable future. Many other countries are on their own e-invoicing journey, only adding to the ongoing complexity of staying up to date (and, as a result, compliant with regulations).

FAQ

Yes. E-invoicing has been mandatory for the public sector since March 2017. As of 1 July 2019, it has been compulsory for all suppliers to issue e-invoices for B2G transactions.

No. There is no general obligation requiring taxpayers to issue e-invoices in B2B transactions. However, since 1 July 2025, the buyer’s right to request an electronic invoice from the supplier has been effective.

Yes. However, the buyer’s consent is needed if the supplier wishes to issue an e-invoice.

On the other hand, since 1 July 2025, if the buyer wishes to receive an e-invoice, they are allowed to demand it from the supplier—as long as the buyer is designated as an e-invoice recipient in the Estonian Commercial Register.

The method of e-invoice exchange is not regulated, allowing the terms of invoice exchange to be agreed upon between the parties.

No specific format is required for e-invoicing in Estonia.

However, since 1 July 2025, if a buyer requests an e-invoice from the supplier—and no specific format has been agreed upon—the European e-invoice standard (EU EN16931) will be used by default.

Portugal E-invoicing

Portugal, like every other country, is on a unique e-invoicing journey. While it was early in adopting digital reporting requirements, the country still has a way to go before electronic invoicing is fully mandated.

This page provides an ideal overview of Portugal e-invoicing. Be sure to bookmark it to stay ahead of future mandate changes.

B2B e-invoicing in Portugal

In Portugal, issuing and receiving electronic invoices for B2B transactions is not mandatory. However, an organisation may voluntarily issue an e-invoice to a buyer upon the buyer’s acceptance.

Some believe that Portugal will not enforce B2B e-invoicing as it has introduced other means of monitoring VAT among private entities – namely ATCUD codes, SAF-T for invoicing and, as of 2027, SAF-T accounting.

B2G e-invoicing in Portugal

The Portuguese government has been working on introducing mandatory electronic invoicing for B2G transactions in recent years.

The mandate’s implementation has been gradual. It began with the mandatory receipt of electronic invoices by the public administrations in April 2019, followed by a phased introduction of mandated issuance of e-invoices for suppliers of the public administration – starting with large companies in January 2021. Currently, only large companies are required to issue invoices electronically.

In Portugal, Law Decree 111-B/2017 and subsequent amendments established the beginning of the obligation to issue, receive and process electronic invoices in public procurement. ESPAP (Entidade de Serviços Partilhados da Administração Pública) is the Portuguese entity responsible for the implementation and management of B2G e-invoicing.

Learn more about B2G e-invoicing in Portugal.

The use of Peppol in Portugal

Portugal’s tax authority utilises the e-invoicing framework and network Peppol for its B2G e-invoicing initiative.

The mandate requires e-invoices to be formatted in a specific way and include set information. Peppol provides a standardised electronic invoice format called Peppol BIS Billing 3.0 that the Portuguese tax authority accepts. Suppliers must use certified invoicing software that supports Peppol (or another accepted e-invoicing standard).

The Government Shared Services Entity (eSPap) is Portugal’s Peppol Authority.

Find out more about Peppol e-invoicing.

Timeline of e-invoicing adoption in Portugal

The following dates mark significant milestones in Portugal’s e-invoicing journey.

  • January 2013: Resident taxpayers must send invoice data to the Portuguese tax administration
  • 31 August 2017: The law governing the country’s e-invoicing system was passed

FAQ

E-invoicing is mandatory for B2G transactions in Portugal, but it is voluntary for B2B. Buyer acceptance is required before e-invoices are issued.

e-Fatura is the online portal of the Portuguese Tax and Customs Authority (AT) that collects and stores invoice data reported through certified billing software. Taxpayers should monitor e-Fatura as it enables tax deduction claims and makes tax filing simpler.

The use of certified billing software is mandatory for the creation of all types of invoices (paper or electronic); this is understood to be the taxpayer’s ERP system.

Since 2021, non-resident companies with a Portuguese VAT registration have also become obligated to issue invoices and other fiscally relevant documents via certified billing software.

Since 1 January 2023, all invoices and fiscally relevant documents must include both a QR code and a unique ID number (ATCUD).

The unique document code (ATCUD) allows a document to be uniquely identified, regardless of its issuer, document type, or series used.

E-invoices must be issued electronically in the CIUS-PT format and transmitted to the public administration through approved channels.

Yes. In Portugal, billing SAF-T has monthly submission requirements and must be completed with the normal VAT return by the 5th day of the month following the reporting period. The Billing SAF-T may be submitted via the e-Fatura portal or web services.

The obligatory submission deadline for the accounting SAF-T file was postponed to 2027 pertaining to the financial year of 2026.

Luxembourg E-invoicing​

Luxembourg is on a typical trajectory regarding its e-invoicing adoption. It wasn’t an early mover, yet it already has a mandate in place—specifically for B2G e-invoicing.

This page provides an overview of Luxembourg’s current e-invoicing rules and regulations. It will be updated as developments occur, so be sure to add it to your bookmarks.

B2B and B2C e-invoicing in Luxembourg

There is no mandate for sending and receiving e-invoices in the context of B2B and B2C transactions in Luxembourg.

Suppliers and sellers may choose to voluntarily issue electronic invoices to other businesses, but they must first obtain permission to do so.

Suppliers and sellers may choose to issue electronic invoices to other businesses voluntarily, but they first need to obtain permission to do so. If they decide to issue e-invoices, the issuer must ensure the integrity of the content and the authenticity of the origin, for example, by using an electronic signature.

B2G e-invoicing

Public sector bodies, central authorities, regional authorities and local authorities must be able to receive and process electronic invoices.

It’s also mandatory for national and foreign economic operators and suppliers of public bodies to submit e-invoices.

The use of Peppol in Luxembourg

All public sector bodies must be able to receive electronic invoices through Peppol’s network.

Ministries and administrations of the State must access Peppol through the Luxembourg Government IT Centre access point. However, as Peppol is a decentralised network, other public sector bodies can use any domestic Peppol Access Point.

In addition to using the Peppol network, suppliers must use the Peppol BIS v3 Billing structure for their e-invoices to public sector bodies.

Bulgaria E-invoicing

Based on the European Directive 2014/55/EU, Bulgaria has legislated the use of e-invoicing in public administrations to receive and process electronic invoices. However, it has yet to implement a mandate for sending invoices electronically.

When it comes to electronic invoicing, every country has its own rules and requirements. This is your ideal overview of Bulgaria e-invoicing.

B2B e-invoicing in Bulgaria

E-invoicing is voluntary for business-to-business transactions in Bulgaria. Consent from the buyer must be obtained before the seller can issue an invoice electronically.

The following methods are accepted for ensuring the integrity and authenticity of electronic invoices:

  • Business Controls Audit Trail
  • Electronic Data Interchange (EDI) or Qualified Electronic Signature​

Invoices must be stored in a way that guarantees their integrity, authenticity, and availability during the five-year required storage period.

B2G e-invoicing in Bulgaria

While governmental bodies must be able to accept and process e-invoices, their suppliers are not required to issue invoices electronically. That means there is no full B2G e-invoicing mandate in Bulgaria.

The Central Automated Information System for Electronic Public Procurement (CAIS EPP) is Bulgaria’s official e-invoicing platform for B2G transactions.

Timeline of e-invoicing adoption in Bulgaria

The key dates in Bulgaria’s e-invoicing efforts are as follows.

  • 1 November 2019: Contracting authorities are required to accept and process e-invoices for public procurement contracts
  • 2021: The National Revenue Agency consults with industry stakeholders about implementing an e-invoicing mandate
  • 9 December 2024: The draft State Budget Act introduces mandatory SAF-T reporting requirements, starting from 2026

Event summary

We’re excited to announce Sovos as a proud exhibitor at the Accounting Summit 2025, taking place this September in Düsseldorf. This event brings together leading innovators and decision-makers in accounting, finance, and tax to explore the digital transformation shaping tomorrow’s financial landscape.

Our very own Christiaan Van Der Valk, General Manager Indirect TaxTech & VP Regulatory, will join the conversation with a session titled:

Decoupling Strategy for Strength: One Compliance Platform, Flexible Automation.

Session Overview:

As governments worldwide increasingly base enforcement strategies on real-time transaction data, companies must rethink how they approach compliance and automation. In this session, Christiaan will explore how organizations can strengthen resilience and agility by building modular, future-proof compliance frameworks, designed for a world where Mirror Visibility is no longer optional.

This session will cover:

  • Truth in the transaction: How governments are turning real-life transaction data and continuous observation of economic operations into the backbone of enforcement strategies.
  • Mirror visibility: Why businesses must be able to see what tax administrations see, ensuring control in an environment where every transaction is monitored.
  • Modular future: How to reimagine automation as composable modules, seamlessly integrated with local compliance functionality, with agentic AI acting as the “super-glue” of tomorrow’s workflows.

Attendees will walk away with a clear vision for building compliance strategies that balance centralization with flexibility, while staying fully aligned with ever-changing regulatory landscapes.

We look forward to connecting with industry peers and exploring the future of compliance, automation, and digital accounting in Düsseldorf!

2025 will be a pivotal year for tax compliance, with governments accelerating e-invoicing mandates, SAF-T requirements and VAT reforms. In this Sovos webinar, Réka Hall, Senior VAT Consultant, will break down the latest updates — from Bulgaria’s SAF-T schema to new mandates across Europe, the Middle East and beyond. Gain clear, actionable guidance to stay compliant, avoid costly errors and future-proof your processes.

As the IRS rolls out Form 1099-DA for digital asset transactions, financial institutions that have long reported on traditional securities through Forms 1099-B, 1099-DIV, and others are encountering a new level of complexity. For firms expanding from traditional finance into digital assets, it is essential to understand both the differences and the overlaps between these reporting frameworks. Join Sovos experts as we break down the specific requirements of 1099-DA reporting, from capturing transaction data to calculating cost basis, and compare them with established reporting processes for stocks, bonds, and other traditional instruments. We will also address the risks of treating digital asset reporting as a separate process (spoiler alert – data silos, inconsistent outputs, and operational strain!) Attendees will walk away with strategies for unifying reporting across asset classes. If you want to ensure accuracy and compliance and deliver a seamless customer experience, you don’t want to miss this.

As your business grows across borders, VAT compliance can quickly become a challenge. In this session, Sovos’ VAT Consultant Michail Konstantinou will break down the essentials of cross-border VAT, from knowing when and where to register to managing non-resident VAT and reclaiming it across multiple jurisdictions.

You’ll gain practical insights into:

We’ll also explore how the right technology can streamline compliance, strengthen audit readiness and reduce manual work — so you can focus on growth.

Whether you’re preparing for your first European market entry or managing rapid international expansion, this webinar will equip you with strategies to stay compliant and maximise VAT recovery.

On 6th August, following multiple consultations throughout 2024 and 2025, the Polish government passed new legislation and updated schemas for its National e-Invoicing System (KSeF). The timeline and criteria for mandatory compliance have been clearly defined under the updated legislation of KSeF 2.0, meaning organisations may have as little as 6 months to prepare.
