Luxembourg VAT Refund: Rules, Deadlines and Procedure

Which Luxembourg VAT refund procedure should you use?

The correct procedure depends on your VAT status in Luxembourg. Before preparing a claim, check whether the company already has a Luxembourg VAT VAT number in Luxembourg, for example in the format LU12345678, or whether it only incurred Luxembourg VAT locally without being registered there.

What counts as recoverable VAT in Luxembourg?

Recoverable VAT is input VAT paid to a supplier or at import for the needs of your economic activity. It should not become a final cost if your business has a right to deduct and the expense meets VAT rules in Luxembourg.

Luxembourg's standard VAT rate is 17%. Some expenses may fall under reduced rates such as 8%, 14% or 3%, but the rate shown on the invoice is not what makes VAT recoverable. The decisive points are the nature of the cost, its link with your taxable activity and the quality of the supporting documents.

VAT charged by mistake is not automatically refundable. A private expense, an incomplete invoice, a supplier error or a cost outside the scope of your business can all block the right to recover Luxembourg VAT.

Who can claim a Luxembourg VAT refund?

Only taxable persons can claim a Luxembourg VAT refund. In practice, this means businesses carrying out an independent economic activity: selling goods, providing services, renting property for business purposes or carrying out an equivalent taxable activity.

Non-taxable profiles are usually outside the refund scope. Private individuals, associations without taxable economic activity, public bodies acting outside a taxable activity and entities unable to prove their taxable-person status generally cannot recover Luxembourg VAT.

Foreign businesses must also prove they did not need a Luxembourg VAT registration for the transactions concerned. If the activity carried out in Luxembourg should have triggered local VAT registration, the AED can reject a standalone refund claim and expect the company to regularise its VAT position. A fiscal representative in Luxembourg can assist in identifying the correct procedure and regularising the VAT position with the AED.

Which expenses can be included in the claim?

Eligible expenses must be incurred for business purposes and must carry a right to deduct under Luxembourg rules. The category alone is not enough. The invoice, the business context and the taxable activity must all support the claim.

A cost accepted in one file can be challenged in another. The AED looks at the transaction as a whole: who bought, who supplied, why the cost was incurred, and whether the document allows a tax audit trail.

How do Luxembourg VAT-registered companies recover VAT?

A company registered for VAT in Luxembourg recovers VAT through its Luxembourg VAT returns. Deductible input VAT is offset against output VAT. If input VAT exceeds VAT due, the balance can be refunded or carried forward to the next period.

Filing is handled through Luxembourg's VAT reporting channels. Since 2020, VAT returns are filed electronically through eCDF. The VAT account position can also be monitored through Luxembourg online services such as MyGuichet.

The refund is faster when the VAT credit is easy to audit. Keep supplier invoices, import documents, accounting reconciliations, deduction period details and the business explanation for the costs. A VAT credit with no audit trail often leads to questions and delays.

How do EU companies not registered in Luxembourg recover VAT?

An EU business not registered for VAT in Luxembourg uses the VAT Refund Directive 2008/9/EC. The application is not filed directly in a Luxembourg portal. It is submitted through the electronic VAT refund portal of the Member State where the business is established, then transmitted to Luxembourg.

The filing deadline is 30 September of the calendar year following the refund period. A late 2008/9 claim can lead to a definitive loss of the refund right.

The European minimum amounts are EUR 400 and EUR 50. A claim covering at least 3 months but less than a full calendar year must reach EUR 400. A claim covering a full calendar year, or the remaining part of a calendar year, must reach EUR 50.

How do non-EU companies recover Luxembourg VAT?

A company established outside the European Union falls under the 13th Directive. The claim is generally annual and is filed on paper with the Luxembourg VAT authority, together with the required supporting documents.

The key deadline is normally 30 June of the following year. The claim relates to Luxembourg VAT incurred during the previous year. Missing this date can make the VAT impossible to recover.

The file must prove both status and substance. The AED will expect evidence that the company is a taxable person, has no establishment in Luxembourg, did not carry out undeclared taxable transactions there and incurred the costs for business purposes.

Luxembourg can apply specific conditions under the 13th Directive. The working source indicates that Luxembourg does not apply a broad general reciprocity filter, but the claim still has to meet Luxembourg documentation, filing and eligibility requirements.

Which documents should you prepare?

A strong VAT refund file is built on consistency, not volume. The tax authority must understand who is claiming, why Luxembourg VAT was paid, how the expense relates to taxable business activity and where the refund should be paid.

How long does a Luxembourg VAT refund take?

For 2008/9 claims, the AED normally has 4 months to review the application. The clock can extend if the authority asks for additional information. Poorly documented claims are the ones most likely to turn into a longer exchange.

For non-EU claims under the 13th Directive, allow around 6 months. The review can take longer if the file is incomplete, if invoices need clarification or if the business status is not clear.

The best accelerator is a clean first submission. Use the right channel, respect the deadline, submit readable invoices and prepare answers to the obvious questions before the AED asks them.

What mistakes block a Luxembourg VAT refund?

Most refusals come from a mismatch between procedure, invoice, activity and deadline. The VAT amount is rarely the only issue.

The most common blockers are:

• filing after 30 September or 30 June;

• using the 2008/9 procedure when Luxembourg VAT registration was required;

• attaching a non-compliant or incomplete invoice;

• claiming VAT charged in error;

• including expenses with no link to taxable economic activity;

• filing for the wrong period;

• failing to answer an AED request for information.
