VAT for SaaS and Digital Products: Where to Register

For software and digital-product sellers, VAT for SaaS and digital products is not a question of where you incorporate. It is a question of where your customers live. Modern consumption tax follows the destination principle: the tax belongs to the country where the buyer is, not the country where the seller is based. Picking a low-tax home base does nothing to lower the VAT you charge a consumer in Berlin, Manchester or Singapore.

That single idea reshapes the whole compliance map. The Organisation for Economic Co-operation and Development reports that every OECD country with a VAT system now requires non-resident vendors to collect tax on cross-border sales of services and digital products (OECD). So as a global SaaS scales, it accumulates registration obligations in market after market, regardless of corporate domicile.

This guide walks the three regimes a growing SaaS hits first — the EU One Stop Shop, the UK, and the US sales-tax patchwork — then the fast-spreading Asia-Pacific rules typified by Singapore. The practical decisions are which EU member state to use as your single registration point, how to handle B2B versus B2C, and when each new threshold actually trips.

TL;DR: Register where your buyers are, not where you incorporate. The EU lets you cover all 27 members with one OSS registration above a EUR 10,000 micro-threshold. The UK imposes a zero threshold on overseas sellers. The OECD average standard VAT rate reached 19.3% in 2024 (OECD).

Why does VAT follow the customer, not the company?

Consumption tax on digital sales is governed by the destination principle: VAT accrues to the jurisdiction where the consumer is located. The OECD's Consumption Tax Trends 2024 confirms that all OECD countries operating a VAT now require non-resident e-commerce vendors to collect VAT or GST on online sales of services and digital products (OECD). Non-resident registration is no longer the exception. It is the norm.

This matters because it kills a common misconception. Founders often assume that incorporating in a zero-tax or low-tax jurisdiction sidesteps VAT. It does not. The corporate income tax you pay on profits and the VAT you collect from consumers are entirely separate systems. A company registered in a tax-free centre still has to charge German VAT to German consumers and remit it to Germany.

The fiscal stakes keep climbing. The average standard VAT rate across OECD countries rose to 19.3% in 2024, up from 19.1% in 2023 (OECD). On a EUR 100 subscription sold into the EU, that is roughly a fifth of the headline price that belongs to a foreign treasury — not your margin to keep.

Key takeaway: VAT registration is driven by where your customers are, not where your company is. Choosing a low-tax base reduces corporate income tax, never the VAT you collect from consumers abroad.

What is the EU One Stop Shop and which threshold applies?

The EU One Stop Shop (OSS) lets you register in a single member state and file one return covering B2C sales across all 27. Since 1 July 2021, OSS replaced the narrower Mini One Stop Shop (MOSS), so a single Member State of Identification now handles every cross-border B2C EU sale (Your Europe). For a SaaS selling into a dozen EU countries, that turns 12 potential registrations into one.

There is a micro-threshold worth knowing. The EU applies a single EUR 10,000 (excluding VAT) EU-wide annual threshold for B2C supplies of telecommunications, broadcasting and electronic (TBE) services, plus intra-Community distance sales of goods. Below it, an EU-established seller may charge its home-country VAT; above it, the customer's country rate applies (European Commission). The services threshold took effect 1 January 2019 and was extended to goods on 1 July 2021.

The Union, Non-Union and Import schemes

OSS is really three schemes, and which one you use depends on where you are established. The Union scheme is for sellers with an EU establishment. The Non-Union scheme is for sellers with no EU establishment, who may pick any one member state to register. The Import scheme (IOSS) handles imported goods up to EUR 150 per consignment (European Commission). Union and Non-Union returns are filed quarterly; IOSS is monthly.

For a pure SaaS or downloadable-product business with no EU office, the Non-Union scheme is usually the relevant one. You select a single member state of identification and file one quarterly return there, even though the VAT itself is divided among the countries where your buyers sit.

Which EU member state should you choose for OSS?

For a non-EU SaaS using the Non-Union scheme, the choice of member state is largely administrative — the VAT rate charged is always the customer's country rate, not the registration state's. So the real selection criteria are language of the portal, quality of the tax authority's English-language guidance, and ease of dealing with the local administration. Ireland's revenue offers English-language processes, while Cyprus, Malta and Estonia are also common picks for English-comfortable, digitally administered registration.

How does the UK treat SaaS and digital services after Brexit?

The UK runs its own VAT system outside the EU OSS, and the threshold split is the trap. UK-resident businesses register once taxable turnover exceeds GBP 90,000 over a rolling 12-month period, with 30 days to register after crossing it (GOV.UK). That sounds generous. For overseas sellers, it disappears entirely.

There is no registration threshold for non-established taxable persons. A business based outside the UK must register for UK VAT from its first taxable supply to the UK, including B2C digital services (GOV.UK). So a US or Singapore SaaS that sells one GBP 10 subscription to a UK consumer has, in principle, a UK VAT obligation from that first sale. The GBP 90,000 threshold simply does not apply to you.

The UK's digital-services rules cover three categories: broadcasting, telecommunications, and electronically supplied services delivered with minimal human intervention — software and updates, website hosting, downloadable e-books, music and games, and online advertising (GOV.UK). Suppliers must keep two pieces of evidence of where each consumer normally lives, such as billing address and IP location.

Where does the US fit if there is no VAT?

The US has no national VAT, but that does not mean digital sellers escape consumption tax. SaaS and digital products fall under state-level sales tax, and most states use an economic nexus standard of $100,000 in sales or 200 separate transactions in the state, measured over the current or prior calendar year (TaxJar). This standard descends from the Supreme Court's South Dakota v. Wayfair decision.

The complication is taxability, which varies wildly by state. Some states tax specified digital products such as e-books but exempt SaaS; others tax only downloaded software and not cloud-hosted tools. The direction of travel is expansion — Louisiana extended sales tax to SaaS, digital products and information services from 1 January 2025 (Sales Tax Institute). What was exempt last year can be taxable this year.

The operational consequence is that the US is not one market but roughly 45 separate sales-tax jurisdictions, each with its own nexus tally, taxability rules and filing calendar. A SaaS crossing $100,000 of sales into a single state may owe registration there even while owing nothing in the state next door — and the 200-transaction trigger can catch low-priced, high-volume products well before the dollar threshold.

How do the Asia-Pacific digital-VAT regimes work?

Asia-Pacific has adopted overseas-vendor registration models that mirror the destination principle, and Singapore is the cleanest example. Under its Overseas Vendor Registration (OVR) regime, an overseas supplier must register for GST if annual global turnover exceeds S$1 million and it makes B2C supplies of remote services or low-value goods to Singapore customers exceeding S$100,000 a year (IRAS). Both limbs must be met.

Singapore's GST rate is 9%, effective 1 January 2024, charged by registered overseas vendors on taxable B2C remote and digital services to Singapore consumers (IRAS). The two-limb design is friendlier than the UK's zero threshold: a small seller with modest Singapore revenue stays outside the net until it is both globally sizeable and materially present in the market. You can review the wider Singapore tax picture on our Singapore jurisdiction profile.

The broader point is that the OECD model is now standard across OECD VAT countries, so the Singapore template — a global turnover gate plus a local sales gate — recurs in many markets with local variations. As you expand into Asia-Pacific, each country needs its own threshold check rather than a single regional registration like the EU's OSS.

Does B2B change where you register?

Yes — the B2B versus B2C distinction is the single biggest filter on whether you register at all. In most VAT systems, cross-border B2B digital sales shift the tax obligation to the buyer through the reverse charge: the business customer self-accounts for VAT in its own country, and the seller does not register there. B2C sales carry no such relief, which is why the OSS, UK and OVR rules above are framed around B2C supplies.

This is why a B2B-only SaaS selling to verified VAT-registered EU businesses may have far lighter registration duties than a consumer app with the same revenue. The relief is conditional: you generally need to validate and store the customer's VAT identification number and treat unverified buyers as consumers. Misclassifying a consumer as a business is where reverse-charge planning unravels.

Where should you register, and in what order?

Sequence your registrations to match where revenue actually concentrates, not where rules feel scariest. The destination principle means obligations appear market by market, so a disciplined approach registers as each threshold is genuinely crossed rather than pre-emptively everywhere. The OECD confirms non-resident collection is now near-universal across OECD VAT countries averaging a 19.3% standard rate (OECD), so eventually a global SaaS touches most of them.

A practical decision matrix for a non-EU SaaS:

Selling B2C into the EU above EUR 10,000? Register once under the OSS Non-Union scheme, choosing one English-friendly member state as your point of identification (European Commission).
Any B2C digital sale to UK consumers? Register for UK VAT immediately — there is no overseas threshold (GOV.UK).
Crossing S$1m global and S$100k into Singapore B2C? Register under the OVR regime at 9% (IRAS).
Crossing $100,000 or 200 transactions in a US state where SaaS is taxable? Register for that state's sales tax (TaxJar).

Frequently asked questions

Do I need to charge VAT if my company is in a tax-free jurisdiction?

Yes, for B2C sales into VAT countries. The destination principle means VAT belongs to the customer's country, and all OECD VAT countries require non-resident vendors to collect it on digital sales (OECD). Your corporate domicile affects income tax, not the VAT you charge foreign consumers.

What is the EU VAT threshold for digital products?

The EU applies a single EUR 10,000 (excluding VAT) EU-wide annual threshold for B2C TBE services and intra-Community distance sales of goods. Below it, an EU-established seller can charge home-country VAT; above it, the customer's country rate applies through the One Stop Shop (European Commission).

Does the UK have a VAT threshold for foreign SaaS sellers?

No. The GBP 90,000 threshold applies only to UK-resident businesses. Non-established sellers must register for UK VAT from their first taxable supply, including B2C digital services (GOV.UK). A single small sale to a UK consumer can create an obligation.

Is SaaS taxable for US sales tax?

It depends on the state. Most states use a $100,000 or 200-transaction economic nexus standard (TaxJar), but taxability of SaaS varies widely, and states keep expanding coverage — Louisiana added SaaS from 1 January 2025 (Sales Tax Institute). Check each state individually.

Do B2B sales need VAT registration abroad?

Often not. Cross-border B2B digital sales frequently shift the tax to the buyer via the reverse charge, so the seller need not register in the customer's country. The relief is conditional on validating and storing the business customer's VAT identification number; unverified buyers are usually treated as consumers.
