Do prices have to say whether VAT is included

EU price indication rules require the total price a consumer pays, tax included, to be unambiguous. For B2B pricing net-of-VAT is normal, but it has to say so — a bare number leaves the buyer unable to tell what they will be charged.

This is rule compliance.price-transparency in the public registry: Prices state whether tax is included. It runs on every audit, against the pages we actually fetched, and its result is derived from the response rather than estimated.

The fix

The same text the audit hands you when this check fails on your own site.

Prices are shown without stating their tax treatment.

EU price indication rules require the total price a consumer pays, tax included, to be unambiguous.

Configuration
€29/month incl. VAT          ← consumer-facing
€29/month plus VAT           ← B2B, stated explicitly
€29/month (VAT calculated at checkout based on your location)

For B2B pricing, net-of-VAT is normal and expected — it just has to say so. A bare number leaves the buyer unable to tell what they will be charged, and it is a common basis for complaints in Germany.

If you sell across borders, VAT depends on the customer's location, so "calculated at checkout" with the final total shown before payment is the honest version.
