VAT on SaaS and digital services

Last reviewed 10 November 2026

A €29-a-month tool subscription raises a surprising number of VAT questions — who charges what, when the One Stop Shop applies, and why the invoice from your app store looks nothing like your own invoices. Both sides of the transaction, worked.

The one rule that runs the whole sector

Treated properly, electronically supplied services are just services — so the freelancers' rule applies first: business customer abroad → no VAT, customer self-accounts; consumer abroad → your VAT. What makes SaaS feel different is scale: a subscription business has thousands of B2C customers in dozens of countries, which is exactly the case the EU's One Stop Shop (OSS) was built for.

The buyer-side corollary matters to every business that buys software: when your SaaS invoice arrives from another country with no VAT on it, that is not a billing error. Your finance team self-assesses the VAT in its own return (reverse charge) and usually reclaims it on the same line. Nothing is "missing" from the invoice.

Selling: a tool company, three customers, three invoices

An Irish SaaS company, list price €29/month, sells to:

A German GmbH (B2B). No Irish VAT. Invoice €29 + the GmbH's DE VAT number + reverse-charge wording. The GmbH self-assesses 19% German VAT (about €5.51) and reclaims it — cash cost to them: €29.
A German freelancer's side project (B2B, has a VAT number). Same as above. The freelance invoicing rule and the SaaS rule are the same rule.
A German consumer (B2C). Irish 23% would be the old world; since the destination principle for digital B2C, German VAT applies — 19% on €29 (about €5.51) is charged as German VAT. Registering in Germany to remit €5.51/month is absurd at any scale below thousands of customers, which is precisely why the Union OSS exists: one quarterly return, filed in Ireland, covering every EU consumer sale at each country's rate.

The threshold wrinkle: a supplier whose total EU cross-border B2C digital sales (plus domestic distance sales) stay under €10,000/year may keep taxing those sales at home (Irish 23%) instead. Above it, destination rates through OSS are mandatory for the EU scheme. The moment a pricing page crosses borders, most SaaS businesses blow through €10,000 in weeks — treat it as a planning tripwire, not a shelter.

What counts as "electronically supplied" (and what doesn't)

Software access, SaaS subscriptions, downloads, cloud storage, streaming, website hosting and automated digital content are all in scope. The automation is the tell: if the order-to-delivery loop runs with minimal human involvement, it's electronic. A consultant delivering a report by email is not; a template pack sold through an automated checkout is. Custom-built software with real human development billed per project behaves like a normal service — B2B reverse charge applies, but the OSS B2C machinery generally doesn't.

App stores change the picture entirely. Sell through the major app stores and the store is, in VAT terms, the supplier to the consumer: it collects and remits the consumer-country tax and hands you a B2B-style statement for your cut. Your OSS obligation usually covers your own website sales — not the store's traffic. This is why "app revenue" and "web revenue" need different VAT treatment in the same business.

Buying: the three-line check on a SaaS invoice

When a foreign SaaS invoice lands with no tax line: (1) confirm your tax number is on it — that's what makes the reverse charge defensible; (2) confirm the wording names the mechanism; (3) book both the output self-assessment and the input reclaim together so they net. If the invoice instead shows foreign VAT (say a US-incorporated tool with Irish VAT registration charging 23%), reclaim routes exist — but the cleaner long-term fix is sending your tax number to the vendor's billing settings so future invoices come clean.

Working the amounts: €29 B2C at 19% is €29 × 19/119 = about €4.62 of German VAT inside a gross €29 — the VAT-fraction trap is the same everywhere, and the reverse calculator handles it in one step. The place-of-supply guide covers the general B2B/B2C decision that underpins all of this.

Record-keeping quirks specific to digital sales

OSS returns require customer-country evidence: billing address, bank country, IP logs, or phone country code all qualify as proof of where the consumer is. Two consistent pieces beat one strong one. Keep them at the transaction level, not the account level — a customer who moves countries mid-subscription generates two different jurisdictions of evidence, and the return follows the invoice date.

SaaS VAT questions

Why does my SaaS invoice show no VAT?

For cross-border business subscriptions the place of supply is the customer's country: you self-assess the VAT by reverse charge in your own return, usually reclaiming it on the same line. Check that your tax number and reverse-charge wording appear on the invoice.

Do I need to register for VAT in every country my SaaS customers live in?

Not if you use the Union One Stop Shop: one quarterly OSS return filed in your home country covers EU consumer sales at each customer country's rate. Outside the EU, separate registrations or deemed-supplier rules (like app stores) apply.

What is the €10,000 rule for digital services?

EU suppliers whose total cross-border B2C digital sales to other EU countries stay under €10,000 in a year may tax them at their home rate instead of the customer's. Above that, destination-country rates through OSS are required.

Does VAT apply differently to downloaded software vs SaaS?

No — both are electronically supplied services with the same rules. What differs is custom-built software billed as a human-delivered project, which follows ordinary service rules instead.

Do app-store sales need OSS reporting?

Usually not: the major stores act as deemed supplier, collecting and remitting consumer tax themselves and paying you a B2B-style settlement. Your OSS return covers sales made directly through your own website.
