EU and UK VAT for Foreign Digital Service Sellers

Last updated: April 2026

VAT obligations for foreign companies selling digital services: EU VAT, UK VAT, and when to register in 2026

You built a SaaS product, connected Stripe, and your customers are in Europe. Then your accountant asks: "Are you registered for VAT in the EU?" You probably aren't. Now what?

The VAT obligations for foreign companies selling digital services are real, they apply from the first sale, and they are not tied to your company's location. Whether you operate through a Delaware LLC, a Dubai free zone entity, or any other structure outside the EU and UK, your VAT obligations follow your customers — not your corporate address.

This guide covers who owes what, the B2B versus B2C distinction (the single most important thing you'll read here), how EU VAT One Stop Shop works for non-EU companies, the UK as a completely separate post-Brexit system, and practical steps to assess your exposure. Enforcement is tightening materially in 2026. The good news is that many founders with primarily B2B businesses have less exposure than they fear.

Who this guide is NOT for

This guide is not for you if:

• You sell exclusively to VAT-registered EU businesses and collect validated VAT numbers for every customer — your obligation is close to zero under the reverse charge mechanism; you do not collect VAT
• You sell only to customers located outside the EU, UK, and other markets covered here — VAT is not triggered by your company structure alone
• You sell physical goods — different VAT rules apply; this guide covers digital services only
• Your business is established in an EU member state — the Union OSS scheme and domestic thresholds apply; this guide focuses on non-EU sellers

If any of the above describes your situation completely, stop here. If you sell digital products or SaaS to consumers or businesses in the EU or UK, read on.

The core rule: where your customer is, that's where VAT is due

The destination principle governs VAT on digital services worldwide. VAT is owed in the country where the customer is located — not where the supplier is registered. This has been the rule in the EU since 2015.

Being incorporated in the US, UAE, Singapore, or anywhere outside the EU does not exempt you from EU VAT obligations. The legal basis is the customer's location, not the seller's. Tax authorities have always had this authority in theory; since January 2026, enforcement has reached a new level of maturity under the EU's VAT in the Digital Age (ViDA) package — with tax authorities now cross-referencing VAT filings against Stripe, PayPal, and other payment processor data.

What counts as digital services for VAT purposes:

• Software as a Service (SaaS) subscriptions
• Software downloads and app purchases
• Online courses and e-learning platforms
• E-books and digital publications
• Streaming services (audio, video, games)
• API access and developer tools
• Website hosting and cloud services
• Digital content subscriptions

If your product is delivered digitally, with minimal human intervention, and consumed electronically, it is almost certainly a digital service under EU and UK VAT rules.

EU VAT for digital services: what foreign companies must know

The threshold reality for non-EU companies

This is the most commonly missed rule among foreign founders, so it bears stating clearly: there is no minimum revenue threshold for non-EU companies selling digital services to EU consumers.

EU-based sellers benefit from a €10,000 annual threshold across all EU member states before pan-EU VAT obligations apply — they can use their domestic rules below that amount. That threshold does not apply to you if your business is based outside the EU. From your very first sale to an EU consumer, VAT is owed at the applicable rate in that customer's country.

A single €15 SaaS subscription sold to a French consumer triggers a French VAT obligation. This is not a technicality that authorities overlook — it is the rule, and ViDA enforcement is making it harder to miss.

B2C sales — you collect VAT, you remit it

When you sell to a private individual, or to any buyer who does not provide a valid EU VAT number, the transaction is B2C for VAT purposes.

You are responsible for:

1. Identifying the customer's EU member state (using billing address, IP address, or other location evidence)
2. Charging the VAT rate applicable in that country
3. Collecting that VAT from the customer
4. Reporting and remitting it to the relevant tax authorities

EU VAT rates vary significantly by member state — from 17% in Luxembourg to 27% in Hungary, with most major markets at 20–25% (Germany 19%, France 20%, Italy 22%, Spain 21%). The OSS scheme, described below, lets you handle all of this through a single registration.

SaaS-specific note: Freemium users who convert to paid, trial accounts, and one-time purchases all follow the same B2C rules if no valid VAT number is provided. The presence of a business email does not make a transaction B2B.

B2B sales — reverse charge applies, your obligation is zero

This is where many founders discover their EU VAT exposure is much lower than feared.

When you sell to a business that provides a valid EU VAT number, the reverse charge mechanism applies. The customer self-assesses and remits VAT in their own country. You do not collect VAT, and you do not remit any. Your invoice states:

VAT: €0 — Reverse charge applies under Article 196 of EU VAT Directive

The critical step: validate the customer's VAT number through the EU VIES system (ec.europa.eu/taxation_customs/vies/) before applying this treatment. If you apply reverse charge without a valid VAT ID and the transaction is later assessed as B2C, you are liable for the unpaid VAT, plus interest and penalties — typically 50–100% of the unpaid amount and 8–12% annual interest on the balance.

Keep records of every VIES validation check. The EU requires a ten-year retention period for VAT records; maintain a log that documents the date and result of each validation.

The practical implication: if you run a B2B SaaS and all your EU customers are VAT-registered businesses with validated VAT IDs, your EU VAT compliance burden is minimal. You invoice without VAT, note the reverse charge, and maintain your records. You are not required to register for VAT or file returns.

EU One Stop Shop (Non-Union OSS) — how to register

For founders with B2C sales to EU consumers, the Non-Union OSS scheme is how you comply without registering separately in every EU member state.

Non-Union OSS is designed specifically for businesses with no EU establishment. It allows you to:

• Register in a single EU member state of your choosing
• File one consolidated quarterly VAT return covering all EU B2C sales
• Remit all EU VAT through that single portal

Registration process:

1. Choose an EU member state to register in. Ireland, Germany, and the Netherlands are common choices for English-language portals and straightforward registration processes
2. Apply online through that country's tax authority portal (for Ireland, this is the Revenue Online Service; for Germany, the Bundeszentralamt für Steuern portal)
3. You receive an EU VAT ID beginning with "EU" — different from a standard member state VAT number
4. Begin filing quarterly returns, reporting sales broken down by member state, applying each country's applicable VAT rate

There is no minimum revenue threshold to register — if you have any B2C sales, register before or immediately after your first sale. Late registration does not eliminate the liability; it simply adds to it.

ViDA context for 2026: The ViDA package, formally adopted March 11, 2025 and in force from April 14, 2025, has shifted enforcement from theoretical to operational. Tax authorities are now cross-referencing OSS filings against payment processor data. Accuracy in your returns is not optional.

UK VAT after Brexit: a completely separate system

The most common structural mistake for founders with both EU and UK customers: EU OSS does not cover the UK.

Since January 2021, the UK operates a fully independent VAT system. If you have customers in both the EU and UK, you need two registrations: EU Non-Union OSS and a separate UK VAT registration with HMRC. There is no unified scheme.

When UK VAT registration is required

Non-established taxable persons (NETPs) — businesses with no establishment or fixed establishment in the UK — face a zero registration threshold for digital services to UK consumers. From your first taxable B2C supply to a UK consumer, you are required to register for UK VAT with HMRC.

• UK VAT rate: 20% standard rate on digital services
• Threshold for NETPs: £0 — from the first sale
• Exception: If all your UK supplies are zero-rated, you can apply to HMRC for an exemption from registration. This is uncommon for digital services

A single sale of a £10 SaaS subscription to a UK consumer triggers registration. The registration requirement exists regardless of how small your UK revenue is.

For UK B2B sales, the same reverse charge logic applies as in the EU: if your UK customer is VAT-registered, they account for VAT themselves. Validate UK VAT numbers via the HMRC VAT number checker.

Making Tax Digital requirements

All UK VAT-registered businesses — including overseas companies — must submit VAT returns through Making Tax Digital (MTD)-compatible software. Paper returns are not accepted.

Compatible software includes QuickBooks, Xero, FreeAgent, and Sage. Most major accounting platforms are MTD-compliant. Returns are quarterly, with payment due one month and seven days after the end of each VAT period.

For a foreign company just registering with HMRC, the practical implication is straightforward: connect your chosen accounting software to HMRC's MTD system before filing your first return. Budget for this setup as part of your compliance stack.

B2B vs B2C VAT obligations: the decision table

Jurisdiction comparison: registration thresholds for foreign digital service providers

Canada note: Canada's Digital Services Tax (originally targeting large platforms) was repealed in June 2025 and is not a concern for most founders.

UAE note: The UAE VAT regime at 5% applies to digital services supplied to UAE consumers above the AED 375,000 threshold. Enforcement of cross-border digital service obligations is still maturing; verify current enforcement guidance with a specialist if UAE is a significant market.

Practical steps: what to do if you're selling to EU or UK customers

Step 1 — Assess your customer base (B2B vs B2C split)

Pull your customer list and identify which customers have provided a valid VAT number. This single exercise will determine most of your actual exposure.

• B2B customers with validated VAT IDs: Reverse charge applies. Minimal EU and UK VAT exposure. Focus on invoice compliance and record-keeping.
• B2C customers (individuals, or businesses without a valid VAT number): You owe VAT at their local rate from the date of each sale.

Validate EU VAT numbers through the EU VIES system. For UK customers, use the HMRC VAT number checker. Do this for every customer, document each check with a date and outcome, and re-validate periodically — VAT registrations can lapse.

If your business is primarily B2B with validated IDs for all EU customers, your compliance burden is low. Document your records, invoice correctly, and you are likely not required to register for VAT at all.

Step 2 — Determine if you need to register

The decision tree is straightforward:

• Any B2C sales to EU consumers? Register for Non-Union OSS immediately. There is no threshold; the obligation exists from the first sale.
• Any B2C sales to UK consumers? Register for UK VAT with HMRC immediately.
• 100% B2B with validated VAT IDs? Registration is not required. Maintain VIES validation records and invoice correctly with reverse charge language.

If you have been selling without collecting VAT, registration does not eliminate retroactive liability — but voluntary disclosure is a far better outcome than being audited. Tax authorities in the EU and UK can assess back three to seven years. Penalty exposure for unregistered businesses typically runs 50–100% of unpaid VAT plus 8–12% annual interest. Address this proactively.

Step 3 — Set up compliant invoicing

For B2C invoices: include the customer's country and the applicable VAT rate. Show the VAT amount as a separate line item. Keep records confirming the customer's location (billing address, IP address, or country selection at checkout).

For B2B invoices: include the customer's VAT ID. State clearly: "VAT: €0 — Reverse charge applies under Article 196 of EU VAT Directive" (for EU) or the equivalent UK wording for UK B2B supplies. Issue B2B invoices within ten days of supply — a ViDA requirement for EU transactions.

Step 4 — Choose your compliance tooling

For most digital businesses, the choice is between:

• VAT compliance software (Quaderno, Anrok, TaxJar): Handles rate calculation, invoice generation, and return filing automatically. Suitable for most SaaS founders with a mix of B2B and B2C.
• Manual filing: Direct OSS quarterly returns filed through the member state portal. Viable only for very low volume with robust spreadsheet tracking.
• Merchant of Record (Paddle, LemonSqueezy): The MoR becomes the seller of record and assumes all VAT obligations. Eliminates your VAT compliance burden entirely. The trade-off is a layer between you and your customers and typically higher per-transaction costs.

If your business has meaningful B2C revenue and you're not already using one of these approaches, the cost of compliance software is almost always lower than the cost of a manual error or missed filing.

Common mistakes foreign founders make

1. Assuming a zero-tax company structure eliminates VAT

A Delaware LLC, Dubai free zone company, or any other offshore entity does not exempt you from EU or UK VAT on digital services. If you're considering your company formation options for international founders, understand that VAT obligations are determined by where your customers are, not where your company is registered.

2. Treating EU and UK as one jurisdiction

Post-Brexit, the EU and UK are entirely separate VAT systems. EU OSS does not cover UK customers. If you registered for EU OSS in 2022 and have UK customers, you have a UK VAT gap. Fix it.

3. Applying reverse charge without validating the VAT number

This is the error that generates the most retroactive liability. If the VIES lookup fails on a VAT number you accepted at face value, and you invoiced without charging VAT, you are liable for the full amount plus penalties. Validate. Record the result. Re-validate periodically.

4. Missing the zero threshold for non-EU companies

The €10,000 annual threshold is available only to EU-based sellers. As a non-EU company, you have no threshold. Many founders operating under Delaware LLC structures for non-residents assume the EU micro-enterprise threshold applies to them. It does not.

5. Ignoring retroactive exposure

Many founders reading this have been selling to EU or UK consumers for one to three years without collecting VAT. Tax authorities can audit back three to seven years. The answer is not to ignore this — it is to quantify the exposure, consult a VAT specialist, and consider voluntary disclosure. Voluntary disclosure typically results in better outcomes than being identified through an audit.

6. Over-complicating a primarily B2B business

If you run a B2B SaaS, all your EU customers are VAT-registered, and you have validated VIES records for all of them, your actual EU VAT compliance burden is close to zero. Don't register for OSS unnecessarily. Invoice correctly with reverse charge language, keep your validation records, and focus on your business.

When you need a VAT specialist

VAT compliance software handles the mechanics well for most founders. A qualified VAT specialist is worth the cost when:

• You have significant B2C revenue — more than €20,000 per year in the EU or more than £10,000 per year in the UK — and are not yet registered
• You have been selling without collecting VAT and need to assess retroactive exposure and voluntary disclosure options
• Your customer mix is unclear — you cannot reliably determine which transactions are B2B versus B2C
• You operate in multiple markets simultaneously (EU, UK, Canada, Australia) with material revenue in each
• Your company is structured in a low-tax jurisdiction and you want a professional view on how VAT intersects with your broader setup — including whether your Dubai free zone company formation or other structure creates any unexpected VAT registration triggers
• You are subject to ViDA platform economy rules (accommodation, ride-hailing, logistics)

This is a domain where specialist cost is almost always justified. Mistakes are retroactive, penalties compound, and voluntary disclosure is meaningfully better than audit exposure.

Conclusion

VAT obligations for foreign companies selling digital services are not theoretical. The EU has a zero threshold for non-EU sellers from the first B2C sale. The UK operates a completely separate system with the same zero threshold for non-established businesses. Enforcement is materially tighter in 2026 under ViDA.

The key insight most founders miss: the B2B versus B2C split determines most of your actual exposure. A B2B SaaS with fully validated EU VAT IDs has minimal compliance obligations. A direct-to-consumer digital product business needs to register and remit from day one.

If you are assessing your company structure and want to understand how your formation choice intersects with VAT obligations across different markets, Atlasway's guides on company formation for globally mobile founders are a useful starting point. VAT does not disappear because your company is offshore — but it can be managed efficiently with the right structure, the right tooling, and the right specialist.
