VAT on Cross-Border Services in Ireland: Reverse Charge and VIES Returns

When an Irish VAT-registered business supplies services to a customer in another country, or buys services from a supplier abroad, the VAT answer depends first on who the customer is, and then on where that customer is established. For business-to-business (B2B) services, Revenue's general rule is that the place of supply is where the receiving business is established, so the customer, not the supplier, accounts for the VAT. That mechanism is the reverse charge, and for supplies to businesses in other EU Member States it is paired with an information return known as the VIES statement. This guide walks through the concepts in outline, based on Revenue's own VAT pages.

VAT on cross-border services is only one strand of an Irish business's wider tax calendar. If you are mapping those obligations, our guide to preliminary tax deadlines and payment rules covers a different set of dates, and cross-border trading often raises wider questions about tax standing, which our tax clearance certificate guide addresses. Rates, thresholds and deadlines change, so check the Revenue pages on the day you rely on them.

Step one: is the customer a business or a consumer?

Revenue's page on the VAT obligations of Irish traders supplying services abroad (published 10 August 2026) says you must confirm the status of your customer, business or private customer, before supplying services abroad. The consequences of getting this wrong are set out plainly: if you treat a customer as a business, do not charge VAT, and the customer turns out not to be a taxable person, you are liable for the VAT, and you may also face interest and penalties following a Revenue audit.

The page says Revenue assumes you acted in good faith, but you must establish whether the customer is a taxable person. You can do this by confirming the customer's VAT number, or by obtaining other proof that the customer is a taxable person or a non-taxable legal person for VAT purposes.

The general place of supply rules for services

Revenue's page on the general place of supply rules for services (published 10 August 2026) sets out two rules.

• Business customers (B2B): the place of supply is where the receiving business is established, whether in the EU or elsewhere. The page gives three ways to locate the customer: where it has established its business, where its fixed establishment is, or, if neither applies, its permanent address or usual place of residence. Where the business customer is outside Ireland, the Irish supplier generally does not charge Irish VAT and the customer self-accounts in its own country.
• Consumers (B2C): the place of supply is where the supplier is established, using the same three-part test applied to the supplier. An Irish supplier to a private customer in another EU state, with no exception applying, therefore has an Irish place of supply.

Revenue illustrates the B2B rule with simple examples. An Irish company supplying a business in France (with no other fixed establishment) has a place of supply in France, so no Irish VAT is due and the French business self-accounts. A US company supplying an Irish-established business has a place of supply in Ireland, so the Irish business must self-account. The page also warns that these general rules can be overridden by certain exceptions and by the use and enjoyment rules. This guide does not cover those exceptions; read Revenue's page on them before relying on the general rule for specialised services.

Supplying services to EU business customers

For B2B supplies to customers in other EU Member States, Revenue's page lists these steps:

• obtain the customer's VAT number and confirm that it is valid;
• record the VAT number on the invoice and keep the transaction records;
• issue an invoice stating that the reverse charge applies;
• check whether the supply is exempt in the other Member State, for VIES purposes; and
• include the supply on your VIES return if it is taxable.

If a new business has no VAT number yet, the page says to obtain a letter from its tax authorities, and a VIES statement is then needed showing the services supplied and the new business's correct VAT number.

Validating a VAT number

Revenue says you can check an EU VAT number on the European Commission's VIES validation website, or by contacting the VIMA office (VIES, Intrastat and Mutual Assistance) within Revenue. Our suggestion: save a dated copy of each validation result with the customer file, because it is the evidence that you checked the status of the customer at the time of supply.

Supplying services to customers outside the EU

For B2B supplies to business customers outside the EU, Revenue's page says such supplies are generally not subject to VAT, but you must still obtain proof that the customer is established outside the EU and evidence that it is a taxable person. Examples of supporting evidence on the page include details from the customer's tax authority, an order form showing the business address and trade registration number, and a printout of the customer's website showing that it carries on an economic activity.

For certain B2C supplies to non-business customers outside the EU, the page says some supplies are free of VAT, but you must obtain proof that the customer is established outside the EU and verify the information provided. It suggests credit card pre-authorisation checks, which can verify the address linked to a card number.

Receiving services from abroad: self-accounting

The reverse charge also applies when you are the customer. Revenue's page on self-accounting for VAT on received services (published 7 July 2026) says a business receiving services from abroad for business purposes may have to account for Irish VAT, whether the supplier is in the EU or outside it. For VAT purposes the recipient is treated as the supplier, and the page states there is no registration threshold for received services.

• VAT-registered businesses account for the VAT in their periodic VAT return, on the invoiced amount, at the appropriate Irish rate. In Revenue's worked example the self-accounted VAT is included in T1 (sales), and the reclaim, if available, is made in T2 (purchases) in the same return.
• VAT-exempt businesses that receive taxable services for business purposes from outside the State must register and account for Irish VAT. Revenue's examples include banks and insurance companies.
• Non-taxable legal persons such as local authorities and State agencies are in scope only if they hold a VAT number. A body without one does not account for VAT on received services.

The page also advises giving your VAT number to the foreign supplier; otherwise you may pay VAT in the other Member State. It says you may be able to reclaim the VAT in the same return but does not set out the conditions for deduction, so check those separately.

VIES returns in outline

Revenue's VIES, Intrastat and Mutual Assistance page (published 24 March 2026) says Irish VAT-registered traders who zero-rate goods, services or both to a VAT-registered trader in another Member State must submit a VIES statement, regardless of the value of the goods or services. There is no threshold.

The VIES Traders Manual (version 2, updated November 2025) adds further detail. It describes the statement as aggregate turnover information: your own intra-EU VAT number, each customer's VAT number including its country prefix, and the total value supplied to each customer in the period. For services, the manual says the supplier may choose monthly or quarterly filing. Statements must be submitted by the 23rd day of the month following the end of the period, and a nil statement is required for a period with no such supplies. Filing is online through Revenue Online Service (ROS), and the manual says VIES statements are separate from VAT3 returns. It also states that a failure to comply carries a penalty of €4,000 per return outstanding. These details were as stated in that manual at the time of writing; confirm the current position before filing.

A practical approach for Dublin finance teams

Dublin-based firms with EU clients often supply the same service to many customers across several countries. A practical approach is a short customer-onboarding checklist:

• record whether the customer is a business or a consumer and how you established that;
• validate and store the VAT number for EU business customers;
• use an invoice template with the reverse charge wording for B2B supplies; and
• reconcile the VIES statement to the sales ledger each period, so a missing customer number is spotted before filing.

For services you buy, a monthly review of foreign supplier invoices for self-accounting is a sensible control. This is our suggestion rather than a Revenue requirement.

What this guide does not cover

This guide does not cover goods, the Intrastat return, the exceptions to the general place of supply rules, electronically supplied services to consumers, or the One Stop Shop schemes. Revenue's pages on those topics should be read separately, and a qualified tax adviser should be consulted for specific transactions. If your cross-border trade involves excisable goods, a separate regime applies; our guide to excise duty authorisation and returns is the place to start.

Frequently asked questions

Does the reverse charge mean I never charge VAT on services to EU customers?

Not quite. Revenue's general rule treats the place of supply for B2B services as where the business customer is established, so an Irish supplier generally charges no Irish VAT to a business customer abroad. For consumers the position differs, and exceptions can override the general rules.

Is there a threshold below which I do not need to self-account for services I receive?

Revenue's page on received services states there is no registration threshold for received services. Check the page for the current position.

Do I have to file a VIES statement for services?

Revenue's page says Irish VAT-registered traders who zero-rate services to a VAT-registered trader in another Member State must submit a VIES statement regardless of value. Check whether the supply is exempt in the customer's Member State, as Revenue's page advises.

How do I check a customer's EU VAT number?

Revenue says you can use the European Commission's VIES validation tool or contact the VIMA office.

What if I treat a consumer as a business by mistake?

Revenue's page says you are liable for the VAT if you misidentify the customer and do not charge it, and interest and penalties may follow an audit. Revenue assumes good faith, but you must establish the customer's status.

Cross-border VAT rules turn on facts and are updated from time to time, so always confirm the position on Revenue's website before filing.
