Tax Implications of Cross-Border Provision of Digital Services

VAT, fixed establishment and new rules.

The tax implications of cross-border digital services depend mainly on who you provide the service to and where the place of supply for VAT is. In addition to correct invoicing, a Prague-based company may acquire the status of an identified person or even a permanent establishment abroad, leading to further tax obligations. The article explains the differences between B2B and B2C, the reverse-charge mechanism, and how to prevent double taxation during expansion.

Key takeaways

  • The place of supply determines where your digital service is subject to taxation. For B2B services within the EU, the place of supply is generally governed by the location of your customer's registered office, whereas for B2C services provided to end consumers, you must apply the VAT rate applicable in the country where the customer resides or has their registered office.
  • Even if you are not a VAT payer, you may still be required to register as an identified person. This obligation arises immediately if you receive a service from a supplier outside the Czech Republic or provide a service to a business entity in another EU Member State; this also applies to routine expenses such as Facebook advertising or software subscriptions.
  • You must register for VAT within 15 days of the obligation arising. If you become an identified person, you are required to register with the tax authority within this period and subsequently remit VAT in the Czech Republic on the relevant transactions; failure to do so may result in penalties.
  • In B2B relationships within the EU, you should utilize the reverse-charge mechanism. As a Czech provider, you issue an invoice to your foreign business partner excluding Czech VAT, with a note stating that the recipient is responsible for declaring and paying the tax in their own country.

The Cornerstone of International Business: How to Properly Handle VAT on Digital Services?

The key to understanding VAT in an international context is the concept of the "place of supply". This determines in which country the tax must be paid. For digital services, the rules differ depending on whether your customer is a business (B2B) or an end consumer (B2C).

When providing services to another business (taxable person) within the EU, the place of supply is generally located in the country where your customer is established. Conversely, if you provide electronic services to an end consumer (non-taxable person), the place of supply is where that consumer is established or resides. This means you must apply the VAT rate applicable in their country.

Have You Become an "Identified Person"? A Hidden Obligation for Non-VAT Payers

Many smaller businesses and sole traders who are not registered for VAT mistakenly believe that cross-border VAT does not concern them. However, this is a dangerous misconception. As soon as you receive a service from a supplier established outside the Czech Republic or provide a service to a business in another EU state, you become an "identified person" (a specific type of VAT registration for non-payers).

This obligation arises immediately and with a very low threshold. It applies to you, for example, when you pay for advertising on Facebook or Google Ads, subscribe to software like Canva or MailChimp, or sell an online course to a company in Slovakia. You must register with the tax authority within 15 days and pay VAT on these transactions in the Czech Republic. 

The Prague-based legal team at ARROWS encounters these issues daily and helps clients with timely registration and the correct setup of processes to avoid penalties.

The Reverse-Charge Mechanism in Practice: Who Actually Pays the Tax?

In B2B relationships within the EU, the reverse-charge mechanism applies. As a Czech service provider, you issue an invoice to your German business partner without Czech VAT. You state on the invoice that the tax will be paid by the customer. 

Your German partner is then obliged to "self-assess" this transaction – i.e., declare and pay German VAT in their tax return. This system simplifies international trade but requires careful verification of partners' VAT numbers in the VIES system and correct invoicing.

An Invisible Trap for Growing Companies: Are You at Risk of Creating a Permanent Establishment Abroad?

While VAT is a frequently addressed issue, a much more serious and hidden risk is the unintentional creation of a permanent establishment abroad. This is not a theoretical problem, but a real threat that can lead to double taxation and unexpected administrative obligations that can jeopardize the profitability of your expansion.

What Is a Permanent Establishment and Why Should Every Managing Director Care?

A permanent establishment is not just a physical office or branch. According to international treaties, it is any fixed place of business through which a company carries out its activities. The creation of a permanent establishment automatically triggers the obligation to register for corporate income tax in that country and pay income tax attributable to this establishment.

How Can Your Sales Representative, a Home-Office Employee, or Even a Server Abroad Trigger a Tax Liability?

In the digital era, the traditional understanding of a permanent establishment is expanding. The risk of its creation does not only apply to companies with physical branches. It is enough for your sales representative in Germany to have the authority to regularly conclude contracts on your behalf, and this can establish a so-called "agency" permanent establishment. Similarly, an employee working permanently from a home office in Austria can create a tax liability for your company in Austria.

Pressure is also mounting on the assessment of digital presence. Although case law is not yet uniform, foreign tax administrations increasingly argue that even a rented server or other key digital infrastructure can, under certain circumstances, constitute a permanent establishment. This is why it is crucial to have contracts with employees and business partners set up to minimize this risk.

At ARROWS, we specialize in preparing and reviewing contracts with an international element that reflect these tax specifics.

The Consequences Are Serious: Double Taxation and Unexpected Obligations

If a foreign tax authority concludes that your company has created a permanent establishment in its territory, the consequences are immediate and significant. You will have to retrospectively register the company for income tax, allocate a portion of your profits to this establishment, and pay the tax, including high late payment interest and penalties. You may also have a 10% withholding tax deducted from payments from your clients in that country. Although double taxation treaties exist, the process of applying them is administratively demanding and can lead to lengthy disputes.

Frequently Asked Questions on International VAT and the Risk of Permanent Establishment

1. When does a Czech non-VAT payer become an 'identified person' when using foreign digital services?

  • A non-VAT payer automatically becomes an identified person by law the moment they receive any service with the place of supply in the Czech Republic from a foreign supplier (e.g., payment for advertising on Facebook/Google Ads, software subscriptions like Canva, MailChimp, or Zoom), or if they provide a service to a business from another EU state. It is necessary to register with the tax authority within 15 days and declare and pay VAT in the Czech Republic.

2. How to correctly proceed with B2B invoicing under the reverse-charge mechanism?

  • When providing a digital service to a business in another EU state, the Czech supplier issues an invoice without VAT and includes a note about the reverse-charge mechanism (reverse-charge). An essential condition is to verify the validity of the foreign customer's VAT number in the European VIES system in advance and report the transaction in the VAT return and recapitulative statement.

3. Can an employee's permanent work from a home office abroad create a permanent establishment for a Czech company?

  1. Yes. If an employee performs work from home abroad (e.g., in Austria or Germany) on a long-term and continuous basis, the local tax authority may conclude that this has created a fixed place of business for the Czech company. The consequence is the obligation to register for corporate income tax in that country, allocate a portion of the profit there, and pay tax according to local regulations.

The Future Is Digital, and So Are Taxes: What Do the ViDA Reform and the Global Minimum Tax Bring?

The European Union and the OECD are not sleeping and are preparing extensive reforms that will fundamentally change the tax environment for the digital economy in the coming years. Companies that do not prepare for these changes in time risk losing competitiveness and incurring high costs for additional implementation.

Are You a Platform? You Will Now Be Responsible for VAT Remittance (the "Deemed Supplier" Principle)

The reform known as "VAT in the Digital Age" (ViDA) brings a revolutionary change for platforms facilitating short-term accommodation and passenger transport. From 2027 (the deadline may still be postponed), these platforms will be considered "deemed suppliers". This means that the platform, and not the actual provider (e.g., the apartment owner), will be responsible for collecting and remitting VAT on the service provided. This step shifts tax liability to major digital players and significantly alters their operating model.

The End of Paperwork: Mandatory Electronic Invoicing and Digital Reporting

Another pillar of the ViDA reform is the introduction of mandatory electronic invoicing for all cross-border B2B transactions within the EU, starting approximately in 2030. Simultaneously, Digital Reporting Requirements (DRR) will be introduced, requiring the transmission of transaction data to tax authorities in near real-time.

This change is not just a formality. For companies, it means the need to invest in compatible accounting and ERP systems capable of generating structured e-invoices and communicating with government portals. This is a fundamental technological and process transformation, and underestimating it could paralyze business operations in the future. ARROWS provides legal consultations on the selection and implementation of these systems and reviews contracts with IT suppliers to ensure full compliance with upcoming legislation.

For Large Players: The Impacts of the Global Minimum Tax (OECD Pillar 2)

For multinational groups with consolidated revenues above EUR 750 million, the OECD initiative known as Pillar 2 introduces a global minimum tax of 15%. The Czech Republic has already implemented this regulation into its legislation under Czech legislation with effect from December 31, 2023, although an amendment is still being prepared to bring the law into full compliance with current OECD interpretations. For large corporations, this means the need for a detailed analysis of their global tax position and potential tax top-ups in countries where effective taxation is below this threshold.

Protect Not Only Your Finances but Also Your Know-How: Legal Certainty First

An effective international strategy is not limited to taxes. When expanding abroad and cooperating with international teams, partners, or suppliers, you expose your most valuable asset – intellectual property – to risk. The protection of your know-how and trade secrets must be an integral part of your legal strategy.

Under Section 504 of the Czech Civil Code, a trade secret consists of competitively significant, identifiable, assessable, and normally unavailable facts in the relevant business circles, which are associated with the business and whose owner adequately ensures their confidentiality. This can include a customer list, pricing policy, or a unique manufacturing process.

The concept of know-how is broader, and the Czech legal system does not explicitly define it. It often involves practical, unpatented knowledge and experience that give your company a competitive advantage. We ensure the protection of these key assets through precisely formulated contractual instruments.

A non-disclosure agreement (NDA) is a cornerstone that must clearly define what constitutes confidential information and how long the confidentiality obligation lasts, even after the cooperation ends.

For key employees with access to sensitive data, a non-compete clause is essential. Under Section 310 of the Czech Labor Code, it must be agreed in writing, can last for a maximum of one year after the termination of employment, and the employee is entitled to monetary compensation of at least half of their average monthly earnings for each month of compliance. ARROWS will help you set up these tools so that they are legally enforceable and effectively protect your business.

Frequently Asked Questions on International VAT, Permanent Establishment, and Expansion Protection

1. What are the main tax and legal risks during international expansion and the sale of digital services?

  • International expansion requires the correct determination of the place of supply for VAT (B2B vs. B2C), monitoring the status of an identified person when purchasing foreign services, and checking the reverse-charge regime. A major hidden risk is the unintentional creation of a permanent establishment abroad. The upcoming EU ViDA reform (e-invoicing) and the necessity of legal protection for trade secrets and know-how must also not be overlooked.

2. When does a non-VAT payer become an identified person and how does invoicing work in B2B mode?

  • A non-payer becomes an identified person within 15 days of receiving any service from a foreign supplier (e.g., payment for advertising on Facebook/Google Ads or a SaaS software subscription) or by providing a service to the EU. In B2B sales in the EU, reverse-charge (transfer of tax liability to the customer) applies – the supplier invoices without VAT but must verify the partner's VAT number in the VIES system in advance.

3. How can a home-office employee or a sales representative abroad establish a permanent establishment?

  • A permanent establishment is created when a company conducts business abroad through a fixed place of business (e.g., an employee's permanent home office) or through a representative with the authority to negotiate contracts. This triggers an obligation to file an income tax return in that country and pay tax on the profit attributable to this establishment. If overlooked, there is a risk of retrospective tax reassessment, high penalties, and late payment interest.

4. What does the EU ViDA (VAT in the Digital Age) reform and the OECD Pillar 2 minimum tax mean in practice?

  • The ViDA reform introduces the responsibility of digital platforms for VAT remittance (deemed supplier principle) from 2027 and introduces mandatory electronic invoicing and real-time digital reporting for cross-border B2B trade in the EU from 2030. Furthermore, businesses with a consolidated turnover above EUR 750 million are subject to a 15% global minimum tax (OECD Pillar 2).

5. How to legally secure trade secrets and key know-how during cross-border growth?

  • Legal protection consists of precisely drafted non-disclosure agreements (NDAs) defining confidential information under Section 504 of the Czech Civil Code. For key employees and representatives, it is necessary to agree on a non-compete clause under Section 310 of the Czech Labor Code (for a maximum of 1 year after the termination of employment, with the obligation to provide monetary compensation).
