Reverse charge: invoicing a European company from a US LLC

Verify the customer, classify the service and issue a coherent B2B invoice from the LLC with VIES, currency and reverse charge properly documented.

A US LLC can provide consulting, software, design, marketing, development and other professional services to a European company while invoicing in USD or EUR from its own legal structure. In many B2B transactions, the LLC does not add European VAT. The customer accounts for the tax in its country under the reverse-charge mechanism.

That outcome does not come from placing a sentence at the bottom of an invoice. Three points must be established first: the buyer is acting as a business, the service falls under the general B2B place-of-supply rule, and the service is supplied to the customer's business establishment or to the fixed establishment that actually receives it.

When those points align, the invoice can remain concise and the LLC keeps a clean international operating record. The agreement, customer validation, service description, currency and tax wording all support one commercial reality: a US company supplies a B2B service and the European recipient accounts for local VAT.

Reverse charge in one precise rule

The EU's general B2B rule places a service where the business customer has established its business. If the service is supplied to a fixed establishment in another country, the location of that establishment can determine the place of supply instead.

Where the supplier is not established in the Member State in which VAT is due, Article 196 of Directive 2006/112/EC makes the business customer liable for the tax on services covered by Article 44. In practical terms:

1. the LLC issues an invoice without adding a European VAT amount;
2. the invoice identifies the customer and the treatment applied;
3. the customer accounts for VAT under the rules of its jurisdiction;
4. the LLC retains the evidence supporting the B2B decision.

This is not an exemption and it is not a special 0% VAT rate. VAT has not vanished; the person responsible for accounting for it has changed. A well-drafted invoice therefore avoids presenting the transaction as “VAT 0%” and states that the customer is liable under reverse charge.

Validate the customer before deciding the invoice

A trading name and a European billing address are not enough to establish B2B status. The LLC should collect the customer's full legal name, address, country, VAT number where available, and the identity of the person contracting for the company.

For a business registered in the European Union, VIES can confirm whether the number provided is enabled for cross-border transactions. VIES is a search engine querying national records, not a standalone database. A useful validation record contains:

• country and number checked;
• valid or invalid response;
• date and time of the query;
• name and address returned or confirmed, where available;
• consultation reference or saved result;
• match with the agreement, purchase order and invoice.

A valid response is strong evidence of business status. An invalid response does not automatically turn the customer into a consumer. Registration may still be pending, cross-border activation may be missing, the number may contain an input error, or the national system may be temporarily unavailable. The professional response is to pause automatic classification and request confirmation from the customer or its tax authority.

Some organisations carry on economic activity before a number is visible in VIES. The VAT Implementing Regulation allows other evidence and reasonable verification steps to be considered. A buyer's unchecked declaration is not enough on its own; the LLC should record why the B2B treatment was accepted.

Our guide to EU VAT for B2B services, VIES and supporting evidence explains the broader framework. This article focuses on turning that analysis into one defensible invoice from a US LLC.

The service itself can change the answer

The general B2B rule covers a broad range of commercial services, but it does not cover every transaction. The real supply must be classified before the invoice is issued.

Email, video calls and online payment do not by themselves make a service electronically supplied. Equally, describing event admission as “consulting” does not remove a special place-of-supply rule that applies to what was actually sold.

If the LLC sells digital services to consumers, the analysis changes. Non-Union OSS for a US LLC selling digital services in Europe explains how the B2C VAT layer can be centralised without breaking up the US structure.

The billing office may not be the recipient

International groups often have one parent signing the agreement, a subsidiary making payment and a team in a third country using the service. The address entered at checkout does not settle the place of supply by itself.

The file should identify:

• the entity signing the agreement;
• the entity bearing the cost;
• the team or establishment receiving and using the service;
• the VAT number belonging to that recipient;
• the country from which instructions are given and work is accepted;
• whether a fixed establishment has sufficient human and technical resources to receive the service.

A mailing address, virtual office or group company that only processes payment does not automatically become the receiving establishment. The decision should follow the contractual and operating facts.

For the LLC, this review also improves the commercial record before billing. The same customer is identified consistently in the proposal, agreement, invoice and payment trail instead of being reconstructed after the quarter has closed.

What the invoice should contain

A strong international B2B invoice should be understandable to the LLC, the customer and the customer's accountant. The following fields form a reliable core:

A clear line can read:

Reverse charge. Customer liable for VAT under Article 196 of Council Directive 2006/112/EC.

Article 226 requires the words “Reverse charge” where the customer is liable for VAT. A local-language translation or legal reference can help the customer post the invoice, but unrelated citations should not be added merely to make the document appear technical.

The EIN should never be labelled as a VAT number. It identifies the company for US federal purposes; it does not make the LLC an EU VAT operator. If the LLC separately holds a European registration for another activity, each identifier needs its own clear label.

EUR, USD and payment rails do not determine VAT

Currency is a commercial and treasury decision. A US LLC can price in EUR to give a European customer certainty or invoice in USD when the agreement is denominated in dollars. It can receive a bank transfer, use a euro account, collect by card or route the payment through a suitable processor.

None of those choices determines:

• whether the buyer is a business;
• how the service is classified;
• where the supply takes place;
• whether reverse charge applies.

The customer converts the amount into its reporting currency under local rules where required. The LLC should retain the original amount, currency, date and amount actually received so that invoice, bank statement and accounting record remain connected.

Receiving EUR through a European IBAN does not, on its own, establish the LLC in the European Union. The account is payment infrastructure; the legal supplier remains the company entering into and performing the agreement.

Five transactions that deserve different decisions

1. Consulting for a Spanish company

The Spanish company provides a valid VAT number, buys for its activity and receives the consulting service in Spain. If the general B2B rule applies, the LLC invoices without adding VAT and includes the reverse-charge wording. The customer accounts for Spanish VAT according to its obligations.

2. SaaS supplied to a French business

The buyer provides a valid French VAT number, purchases access for business use and is the actual recipient. The invoice identifies both companies, does not add supplier VAT and uses reverse charge. A digital product remains B2B when the customer is acting as a business.

3. Design ordered by a German parent for an Italian subsidiary

It is not enough to invoice whoever made the payment. The LLC must identify which entity receives the service and whether a fixed establishment is involved. Agreement, briefing, users, acceptance and VAT ID should point to the same recipient.

4. Admission to an event in Portugal

Admission to certain events can follow a special rule linked to the event location. The general reverse-charge analysis should not be applied simply because the buyer has a VAT number. The transaction needs to be classified before billing.

5. A number that VIES cannot confirm

The LLC asks for additional evidence instead of forcing an automatic B2B invoice. The customer may confirm activation with its authority, provide business evidence or correct an input error. If business status remains unsupported, the treatment follows the facts that can actually be established.

Choices that weaken an otherwise strong invoice

An international structure does not need more wording; it needs consistent decisions. Avoid:

• writing “VAT 0%” without describing the mechanism;
• calling the service exempt when it is taxable in the customer's country;
• using a VAT number belonging to another group entity;
• assuming every genuine European business must already appear in VIES;
• applying the general rule to property, events or another special service;
• placing an EIN and VAT number in one ambiguous field;
• changing customer identity or currency between agreement, invoice and payment;
• relying only on the card country or bank location;
• invoicing a brand without identifying its legal entity.

The answer is not a longer disclaimer. It is better data at the start and a stable invoicing policy for each category of service.

A US LLC is much more than an invoice issuer

Reverse charge is one operating rule, not the reason to own a US LLC. The structure can bring contracts, intellectual property, services, multi-currency banking, payment processors, an international team and reinvestment together within one company.

Its invoices carry more authority when that business reality is visible:

• the LLC is the supplier in the agreement and terms;
• the service belongs to its genuine activity;
• payment reaches a coherent business account;
• the payment descriptor matches the brand;
• the customer knows who is responsible for delivery;
• corporate and tax records are current;
• each transaction can be followed from order to statement.

The LLC's US federal tax classification does not decide European VAT. A single-member LLC, partnership or LLC with a corporate election can all supply B2B services. The European invoice treatment follows the transaction and customer. Coordinating both layers allows the structure to be used confidently without reducing it to a bank account.

How Exentax supports the structure

Exentax reviews the complete transaction: contracting entity, service category, customer country and status, receiving establishment, contractual wording, invoice, currency and payment route. The tax treatment becomes part of a coherent international structure rather than an isolated note.

We also design the evidence policy, the criteria for accepting a VAT number, the exceptions requiring review, and the connection between US banking, euro accounts, processors and invoicing. The goal is a clear, scalable policy that lets the LLC serve European businesses professionally.

Frequently asked questions about reverse charge and a US LLC

Does a US LLC need an EU VAT number to invoice an EU company?

Not necessarily. Under the general B2B rule, the European customer can be responsible for VAT through reverse charge. The LLC must identify itself correctly as a US business and retain evidence of the recipient. A fixed establishment, other activities or a special rule can still create a registration requirement.

Which VAT number belongs on the invoice?

The number of the customer receiving the service, where applicable and validated. The LLC's EIN should be shown as its US tax identifier, not as a VAT number.

Should the invoice state “VAT 0%”?

It is better not to present reverse charge as a zero rate. The supplier does not add a VAT amount and the invoice states “Reverse charge” because the customer accounts for the tax.

Does an invalid VIES response make the sale B2C?

Not automatically. There may be an input error, pending activation or national-system outage. The LLC should obtain further evidence and document the decision before applying B2B treatment.

Can the LLC invoice a European customer in dollars?

Yes, when USD is agreed. Currency does not determine the place of supply or prevent reverse charge. Amount, currency, due date and payment reference should be explicit.

Does reverse charge apply to every service?

No. It is common for B2B services under the general rule, but property, events, catering, transport and other supplies can follow special rules. The service must be classified first.

Does a European bank account change the LLC's residence?

Not by itself. An IBAN or collection account is financial infrastructure. Establishment, activity and the contractual relationship depend on wider legal and operating facts.
