Intra-EU VAT refers to the Value Added Tax rules governing the supply of goods and services between EU member states, including the reverse charge mechanism.

Intra-EU VAT refers to the specific set of Value Added Tax rules that apply when goods or services are supplied between businesses located in different European Union member states. These rules exist to ensure that VAT is collected fairly across borders without creating double taxation or administrative barriers to trade within the single market. For Irish businesses selling to or buying from companies in other EU countries, understanding intra-EU VAT is essential for correct tax compliance.
The cornerstone of intra-EU VAT for goods is the concept of intra-community supplies and acquisitions. When an Irish VAT-registered business sells goods to a VAT-registered customer in another EU member state, the supply is generally zero-rated in Ireland. The customer then accounts for the VAT in their own country through the reverse charge mechanism. This ensures that VAT is paid in the country of consumption rather than the country of origin.
For services, the rules depend on the type of service and the status of the customer. Most B2B services follow the "place of supply" rule, meaning VAT is charged where the customer is established. This is handled through the reverse charge, so the Irish supplier does not charge Irish VAT. B2C services follow different rules and may require the Irish supplier to register for VAT in the customer's country or use the One Stop Shop (OSS) scheme to simplify compliance.
The reverse charge is the central mechanism underpinning intra-EU B2B trade. Instead of the supplier charging VAT and remitting it to their local tax authority, the responsibility shifts to the customer. The customer self-accounts for the VAT on their own return, both declaring the output VAT due and reclaiming it as input VAT in the same period. This means the transaction is typically VAT-neutral for the customer, provided they have full VAT recovery rights.
For Irish businesses, the reverse charge simplifies cross-border trade considerably. When you sell services to a VAT-registered business in Germany, for example, you issue an invoice without Irish VAT and include the customer's VAT number along with a note stating that the reverse charge applies. Your German customer then reports the VAT on their German return. This avoids the need for you to register for VAT in every EU country where you have customers.
However, the reverse charge only applies when both parties are VAT-registered and the supply qualifies under the relevant rules. If your customer is not VAT-registered, or if the supply relates to certain categories like property or events, different rules may apply. Getting these distinctions right is critical, and your accountant should review your cross-border transactions regularly.
When an Irish business ships goods to a VAT-registered buyer in another EU member state, this is classified as an intra-community supply. The supply is zero-rated in Ireland, meaning no Irish VAT is charged, provided certain conditions are met. You must hold the customer's valid VAT number, the goods must physically leave Ireland, and you must retain proof of dispatch such as shipping documents or carrier receipts.
The corresponding acquisition by the buyer is called an intra-community acquisition. The buyer accounts for the VAT in their own country at their local rate. As an Irish supplier, you must report these transactions on your VAT return and also file a VIES (VAT Information Exchange System) return, which allows tax authorities across the EU to cross-check intra-community trade and detect fraud.
The One Stop Shop was introduced to simplify VAT compliance for businesses selling goods or digital services to consumers across the EU. Before the OSS, businesses that exceeded distance selling thresholds in individual member states had to register for VAT in each country. The OSS allows you to report and pay VAT on all qualifying B2C cross-border sales through a single return filed with Revenue in Ireland.
This is particularly relevant for Irish e-commerce businesses and SaaS providers. If you sell digital services to individual consumers across Europe, the OSS means you can handle all the VAT obligations from one portal rather than managing multiple foreign registrations. The VAT is charged at the rate applicable in the customer's country, so you need to know the correct rates for each member state where you have customers.
Correct invoicing is fundamental to intra-EU VAT compliance. For intra-community supplies and reverse charge services, your invoice must include both your Irish VAT number and the customer's VAT number from their member state. You should include a clear statement indicating the reverse charge applies, such as "VAT reverse charge" or a reference to the relevant EU Directive article. Failing to include these details can result in the zero-rating being denied by Revenue.
You must also validate your customer's VAT number before each transaction using the VIES database, which is freely accessible online. Recording the date and result of each validation protects you if Revenue queries the zero-rating of a supply. Strong record-keeping practices, combined with accurate financial statements, are your best defence during an audit.
One of the most common mistakes is failing to verify the customer's VAT number before zero-rating a supply. If the number is invalid or the customer is not genuinely VAT-registered, Revenue can deny the zero-rating and assess Irish VAT on the transaction. Another frequent error is not filing VIES returns on time, which can trigger compliance queries from both Irish Revenue and the tax authority in the customer's country.
For startups expanding into EU markets, it is important to build intra-EU VAT considerations into your systems from the outset. Work with your accountant to ensure your invoicing software captures the correct details, your VAT registration is appropriate for your activities, and your tax registration reflects any cross-border obligations. Getting the foundations right early prevents costly corrections later and supports smooth scaling across the company formation lifecycle.
