VAT and GST Registration for Cross-Border Digital Services 2026

If you sell SaaS subscriptions, digital content, or online services to customers in other countries, you probably owe VAT or GST somewhere you haven't registered yet. The number of countries requiring non-resident digital service providers to collect and remit indirect tax has grown from a handful in 2015 to over 100 in 2026. The compliance burden is real, and ignoring it doesn't make the obligation disappear.

The basic principle

Most countries now tax digital services at the place where the customer is located, not where the provider is based. If you're a SaaS company in the US selling to customers in Germany, Germany expects you to charge German VAT (19%) and remit it to the German tax authority. This is a departure from how physical goods taxation traditionally worked, and it catches many digital-first businesses off guard.

The obligation typically applies to B2C sales (business-to-consumer). For B2B sales (business-to-business), many jurisdictions use a reverse charge mechanism where the business customer self-assesses the VAT, removing the obligation from the non-resident provider. But the B2B reverse charge doesn't apply universally, and determining whether a customer is a business or consumer requires its own compliance process.

EU: the One Stop Shop

The EU's One Stop Shop (OSS) is the most practical simplification mechanism available. Instead of registering for VAT in each of the 27 EU member states where you have customers, you register in one member state and file a single quarterly OSS return covering all your EU B2C digital service sales. The OSS portal distributes the VAT to each member state based on where the customers are located.

Non-EU businesses use the non-Union OSS scheme, which requires registering in any one EU member state (Ireland is the most common choice for English-speaking providers). You charge VAT at the rate of the customer's country (which ranges from 17% in Luxembourg to 27% in Hungary), report all sales on a single quarterly return, and make one payment. The OSS eliminates the need for 27 separate registrations, which would be impractical for most small and mid-sized digital businesses.

There is no revenue threshold for non-EU businesses selling digital services to EU consumers. From the first euro of sales, you owe VAT. EU-based businesses selling to consumers in other member states have a EUR 10,000 annual threshold before the destination-country VAT rules apply (below that, they charge their home country rate). This threshold does not apply to non-EU sellers.

What qualifies as a "digital service" under EU rules: SaaS, cloud computing, website hosting, digital downloads (software, ebooks, music), online advertising, online gaming, streaming services, and online learning platforms where content is delivered electronically with minimal human involvement. Consulting delivered via video call is generally not a digital service, because the human involvement is substantial.

United Kingdom: separate registration post-Brexit

Since Brexit, the UK operates its own VAT system for digital services, entirely separate from the EU OSS. Non-UK businesses providing digital services to UK consumers must register for UK VAT if their taxable supplies exceed the registration threshold. For non-established businesses (no UK establishment), there is technically no threshold: you must register from the first sale.

The UK VAT rate is 20%. Registration is done directly with HMRC, and you file quarterly returns. There is no UK equivalent of the OSS for consolidating returns across jurisdictions, because the UK is a single jurisdiction. The process is straightforward but adds another registration and filing obligation on top of your EU OSS return.

The UK does not have a low-value threshold exempting small digital sellers. If you sell a single GBP 9.99 SaaS subscription to a UK consumer, you technically owe UK VAT. In practice, HMRC's enforcement capacity means very small sellers may fly under the radar, but the legal obligation exists from pound one.

Australia: GST on digital imports

Australia has required non-resident providers of digital services to register for GST since July 2017. The threshold is AUD 75,000 in annual Australian sales (AUD 150,000 for non-profit organizations), unchanged since the regime launched in July 2017. The GST rate is 10%. Registration is done with the ATO, and a simplified registration and reporting system is available for non-resident digital service providers that reduces the administrative burden.

Under the simplified system, you charge 10% GST on B2C digital sales to Australian consumers, file quarterly Business Activity Statements, and remit the GST. You cannot claim input tax credits under the simplified system (you'd need full GST registration for that, which comes with more extensive obligations). For most non-resident digital service providers, the simplified system is the practical choice.

Australia's definition of digital services aligns broadly with the EU's: streaming, SaaS, digital downloads, online gaming, and similar electronically delivered services. B2B sales to Australian GST-registered businesses are generally handled through reverse charge, similar to the EU approach.

Singapore: expanded GST scope

Singapore extended its GST to imported digital services in January 2020, requiring non-resident providers with annual global turnover exceeding SGD 1 million and B2C sales to Singapore customers exceeding SGD 100,000 to register under the Overseas Vendor Registration (OVR) regime. The GST rate increased to 9% from January 2024.

The dual threshold (global turnover AND local sales) means smaller businesses selling modest amounts to Singapore customers often fall below the registration requirement. But once you cross both thresholds, registration is mandatory, not optional. Singapore's approach is efficient: the OVR registration process is online, filing is quarterly, and the IRAS (Inland Revenue Authority of Singapore) provides clear guidance.

From 2023, Singapore also requires registration for B2B imported services in certain situations, specifically where the Singapore business customer is not entitled to full input tax credits. This is a narrower obligation but one that catches financial services and other partially exempt businesses.

Other jurisdictions to watch

The list of countries with digital services VAT/GST obligations continues to grow. Notable regimes include:

Canada: Non-resident digital service providers must register for GST/HST if they have Canadian B2C sales exceeding CAD 30,000 over 12 months. The federal GST is 5%, with provincial HST adding up to 10% more depending on the province. The CRA administers a simplified registration framework.

Japan: Non-resident providers of B2C digital services must register for Japanese consumption tax (10%) if their taxable sales exceed JPY 10 million (approximately USD 65,000), based on prior-period taxable sales. The National Tax Agency administers the regime, and compliance requires filing in Japanese or through a tax agent.

South Korea: Non-resident digital service providers register with the National Tax Service for 10% VAT. Major platforms like Google, Apple, and Netflix have been registered since 2015. The regime extends to SaaS and cloud services.

India: Non-resident providers of online information and database access or retrieval services (OIDAR) must register for GST at 18%. The threshold is zero: any OIDAR supply to a non-taxable Indian consumer triggers the obligation.

Compliance platforms and when to use them

Managing VAT/GST obligations across 10+ jurisdictions manually is possible but painful. Each jurisdiction has its own registration process, filing frequency, format requirements, and payment methods. The administrative cost of doing this in-house (staff time, tax advisor fees, foreign bank accounts for payments) adds up quickly.

VAT compliance platforms like Taxamo (now part of Vertex), Paddle (which acts as a merchant of record, absorbing the VAT obligation entirely), Stripe Tax, and Avalara automate rate determination, tax calculation at checkout, and in some cases filing and remittance. Costs range from 0.5-1% of transaction value (Stripe Tax) to 5-10%+ of revenue (merchant of record models like Paddle that handle everything including payment processing).

The merchant of record model deserves particular attention. When a platform like Paddle or FastSpring acts as the merchant of record, they are the seller to the end customer, not you. They handle VAT registration, collection, filing, and remittance in every jurisdiction. You receive a net payment from the platform. This eliminates your VAT compliance burden entirely but at a significant cost (typically 5%+ of revenue) and with loss of direct customer billing relationships.

For businesses with under $500,000 in international digital service revenue, a merchant of record is often the most cost-effective approach when you factor in the full cost of managing multi-jurisdiction VAT compliance yourself. Above $1 million, the math shifts: the percentage-based fee becomes expensive, and investing in proper VAT infrastructure (registration, automated filing via a platform like Avalara or Taxually, and a tax advisor for ongoing compliance) usually costs less.

Common mistakes

The most frequent error is simply not knowing the obligation exists. Many US-based SaaS companies sell to European customers for years before discovering they should have been charging EU VAT from day one. The back-liability can be substantial: EU VAT authorities can assess up to five years of unpaid VAT in most member states, plus interest and penalties.

The second mistake is relying on customer self-declaration for B2B verification. Under EU rules, you need two pieces of non-contradictory evidence to determine a customer's location (IP address, billing address, bank country, SIM card country). For B2B exemptions, you need the customer's VAT identification number, verified against the VIES database. Accepting a customer's word that they're a business, without verification, doesn't protect you.

Third: assuming that because a marketplace (like AWS Marketplace or Salesforce AppExchange) handles billing, the VAT obligation is handled. Some marketplaces act as merchant of record for tax purposes, others don't. Read the terms carefully. If the marketplace is simply processing payments on your behalf without assuming the seller role, you remain the taxable person.

The landscape is only getting more complex. Countries that haven't yet implemented digital services VAT are steadily joining. The compliance cost is a real business expense that belongs in your financial planning, not something to discover during an audit.
