EU Reverse Charge Invoice Requirements

By Remco from Avatcado

Once you have established that reverse charge applies, issue an invoice using the applicable national rules. This guide focuses on ordinary cross-border B2B services supplied by EU businesses. Non-EU suppliers should check which invoice rules apply to them; a US supplier should not invent an EU VAT number for an invoice. See the reverse charge guide for developers for the separate tax-treatment assessment.

Core invoice fields

Article 226 of the VAT Directive sets out invoice particulars, including:

  • The issue date and a sequential number uniquely identifying the invoice.
  • The supplier's VAT identification number, full name and address.
  • The customer's full name, address and VAT identification number when liable for VAT.
  • The extent and nature of the services, and the supply date when different from the issue date.
  • The taxable amount and applicable pricing details, subject to the Article 226a simplification below.
  • The mention "Reverse charge" when the customer is liable for VAT.

VAT numbers and reverse charge wording

Article 226(4) requires the customer's VAT number for supplies on which the customer is liable for VAT. Article 226(11a) requires the mention "Reverse charge" in the English text. A longer explanation or an Article 196 reference can add context but does not replace the required mention. Follow the applicable national language and invoice requirements.

No VAT charged by the supplier

Reverse charge shifts liability to the customer; it does not make the service subject to a statutory 0% rate. Under Article 226a, a non-established supplier making a supply to a customer liable for VAT may omit the particulars in Article 226(8), (9) and (10), instead identifying the taxable amount by reference to the extent and nature of the supply. This is the relevant simplification, rather than a universal instruction to print 0%. Use your jurisdiction's reverse charge invoice format.

Whose national invoicing rules apply?

Article 219a generally links invoice rules to the Member State where the supply takes place. Its exception for a supplier established in another Member State, where the customer is liable, normally points to the supplier's Member State. Customer self-billing is an exception to that exception. A supplier outside the EU cannot simply apply the rules of a nonexistent EU home Member State; check the rules governing that supply.

If the buyer's VAT number is invalid or unavailable

Keep a live invalid result separate from a timeout, stored outage result or API error. None independently determines that VAT must be charged. Ask the customer to correct details or supply supporting evidence, and resolve its status, establishment and the transaction rules before finalizing the treatment.

Use the runnable registration-evidence example to save the timestamp, source, request ID and consultation number when returned. The requester number is optional and must be genuine. Supplying it disables cache reads and register fallback by default; explicit cache=true or fallback=true opts back into the corresponding path. Store a consultation number only when it is returned. Missing consultation proof should remain missing in your record; do not substitute the time of a later cache read. For checkout placement, see the SaaS billing integration guide.

Credit notes and corrections

A later invalid result does not by itself establish that an earlier invoice was wrong. Review the evidence and circumstances at the time of that supply. If a correction is needed, Article 219 treats a document that amends and specifically refers to the original invoice as an invoice. Follow the national correction process, which may involve a credit note and replacement invoice. Revalidate recurring customers according to your documented policy, and review changes before the next invoice.

Recapitulative statements

Article 262 covers relevant intra-EU services for which the recipient is liable under Article 196, including conditions concerning the recipient's VAT identification. EU suppliers should check the applicable filing requirements and deadlines with their tax authority. This EC Sales List obligation must not be generalized to every non-EU supplier selling SaaS to an EU business.

Reverse charge invoice checklist

  • Document why reverse charge applies to this supply.
  • Identify the governing national invoice rules, including any self-billing arrangement.
  • Include the required identifiers, dates, customer details and service amount.
  • Include the reverse charge mention and use the applicable display convention.
  • Retain registration evidence separately from the tax-treatment decision.
  • Complete the relevant reporting and correction processes.

Frequently asked questions

What exact wording satisfies the 'Reverse charge' legend requirement?

Article 226(11a) requires the mention Reverse charge in its English text when the customer is liable for VAT. Follow the applicable national language and invoice rules. A longer explanation or an Article 196 reference can add context but does not replace the required mention.

Does a reverse charge invoice need to show a VAT rate or amount?

Reverse charge shifts VAT liability to the customer and is not a statutory 0% rate. Article 226a permits a qualifying non-established supplier to omit the details in Article 226(8), (9) and (10), instead identifying the taxable amount by reference to the extent and nature of the supply. Use the applicable national invoice format rather than assuming every invoice should print 0%.

What should I do if I already issued a reverse charge invoice and the buyer's VAT number later turns out to be invalid?

Review the facts and evidence at the date of the supply. A later invalid number does not by itself establish that the original invoice was wrong. If correction is required, follow the national process. Article 219 treats a document amending and specifically referring to the original invoice as an invoice. Keep the original evidence and document the reason for any correction.

Whose national invoicing rules apply to a cross-border B2B reverse charge invoice?

Article 219a generally points to the Member State where the supply takes place. For an EU supplier established in another Member State where the customer is liable, the exception normally points to the supplier Member State, subject to the customer self-billing exception. A non-EU supplier cannot assume it has an EU home Member State for invoicing; check the rules applicable to the supply.
