How the Same EU SaaS Subscription Can Be Taxed Four Different Ways

Selling a software subscription from an EU country triggers up to four distinct VAT treatments depending on the buyer's location, type, and VAT registration status. A business customer in another EU state with a valid VAT ID qualifies for a reverse charge, meaning no VAT is collected, but only if the seller has actively validated that ID at checkout. Consumers in other EU states are charged their home country's VAT rate, which sellers can report centrally through the EU's One Stop Shop scheme to avoid registering in every member state. Buyers in the seller's home country pay the local rate, while customers outside the EU generally fall outside EU VAT scope, though many non-EU countries have their own digital services taxes. Critically, each of these branches carries strict evidence requirements — including stored location data and VAT validation records — that must be retained for up to ten years to survive a tax audit.
