In plain words
EU VAT is the harmonised value added tax system in force in the European Union. Although VAT is a national tax of each country, in the EU it is subject to common rules (directives) that standardise the mechanism and facilitate the single market. The VAT rates themselves, however, remain different: each EU country sets its own standard and reduced rates within common limits.
The main complexity is cross-border transactions within the EU. For transactions between businesses (B2B) the reverse charge mechanism often applies, under which the buyer accounts for VAT in their own country. For sales to consumers (B2C), especially of digital services and goods sold online, special rules and simplified reporting systems apply (such as the One-Stop Shop, OSS), allowing VAT across the whole EU to be declared in one place.
For a business operating in the European market or selling to customers in the EU, administering VAT correctly is a must. Mistakes with cross-border VAT lead to penalties and problems. When planning a structure and activity in Europe, we take the EU VAT rules into account so that the tax is administered correctly and the business complies with the Union’s requirements.

Frequently asked questions
01 /What is EU VAT?
The European Union’s harmonised value added tax system: VAT remains a national tax but is subject to common EU rules (directives).
02 /Are the rates the same in every EU country?
No. Each country sets its own standard and reduced rates within common EU limits. The mechanism is common, but the rates differ.
03 /How does VAT work in B2B transactions within the EU?
The reverse charge often applies: the buyer accounts for VAT in their own country rather than the seller charging it. This simplifies cross-border B2B transactions.
04 /What is the OSS?
The One-Stop Shop — a simplified reporting system that allows VAT on sales to different EU countries to be declared in one place, without registering in each.
05 /What are the rules for digital services?
For B2C sales of digital services and goods sold online, special rules on the place of taxation and reporting through the OSS apply. We help apply them.
06 /What are the consequences of EU VAT mistakes?
Penalties and problems with the tax authorities of different countries. Cross-border VAT is complex, so it is important to administer it correctly from the start.
