Alternative Proof of Export - What Can Replace the Export Confirmation?
The export confirmation (CC599C in Poland, Ausgangsvermerk in Germany) message is the standard and safest proof that goods have left the EU customs territory, entitling the exporter to the VAT zero rate. But what if the exporter cannot obtain it? EU and national tax law allows the use of alternative proof of export - but under strictly defined conditions and with significant risk. In this article we analyse which documents can replace the export confirmation, when this is permissible, and why closing the MRN and obtaining the export confirmation is always the better solution.
Legal Basis - EU and National VAT Law
The documentation of export for VAT purposes is governed by EU-wide and national rules. At the EU level, the key provisions are found in the VAT Directive (2006/112/EC) and the Union Customs Code (Regulation 952/2013). At the national level, each Member State implements these requirements - for example, in Poland through Article 41 of the VAT Act of 11 March 2004. The core rules are:
- VAT zero rate applies to export supplies provided the exporter holds, before the VAT return deadline, a document confirming that the goods left the EU customs territory.
- Primary evidence is the electronic export confirmation message from the customs system (CC599C in Poland, Ausgangsvermerk in Germany, confirmation of exit in the Netherlands) - generated when the customs office of export confirms completion of the export procedure.
- Alternative evidence is not explicitly listed in most national VAT laws as sufficient. Its admissibility stems from CJEU case law, national court rulings, and individual tax interpretations.
Under Polish law, Art. 41(6a) of the VAT Act specifically allows alternative documents to replace the export confirmation as proof of export for VAT 0% purposes, provided that obtaining the standard confirmation was objectively impossible. The statutory framework nonetheless strongly favours the standard export confirmation (CC599C in Poland, Ausgangsvermerk in Germany) as the definitive proof. Alternative documents carry inherent legal uncertainty.
Types of Alternative Proof of Export
Below are the documents that, in practice, tax authorities have accepted as alternative proof of export in certain circumstances. Each has its limitations.
1. Bill of Lading (B/L)
A maritime Bill of Lading is issued by the carrier or its agent, confirming acceptance of goods on board a vessel. It contains details of the shipper, consignee, port of loading and discharge, cargo description, container number, and date of loading.
Strengths: Confirms physical loading onto a vessel at a specific EU port with a destination outside the EU. It is a commercial document with recognized evidential weight.
Weaknesses: Does not confirm that the vessel actually reached the port of discharge. Goods may have been transhipped, confiscated, or returned. The tax authority may argue that B/L alone does not prove that goods left the EU customs territory.
2. CMR Consignment Note
CMR (Convention relative au contrat de transport international de Marchandises par Route) is the international road transport consignment note. It confirms acceptance of goods for carriage and the conditions of transport.
Strengths: Widely used, readily available, contains details of consignor, consignee, and route.
Weaknesses: Confirms only that goods were handed over for transport - not that they were delivered or left the EU. In the case of maritime export (goods travel by road to a port, then by sea), CMR documents only the road leg to the port.
3. Delivery Confirmation from the Foreign Buyer
A written statement from the overseas buyer confirming receipt of the goods at the destination (outside the EU). This may take the form of an email, formal letter, or signed proof-of-delivery document.
Strengths: Directly confirms that goods arrived outside the EU.
Weaknesses: Easy to fabricate, difficult for the tax authority to verify. Credibility depends on the form and level of detail - a generic "I confirm receipt" statement carries less evidential weight than a detailed document with date, goods description, and reference numbers.
4. Forwarding Documents (FIATA, AWB)
Documents issued by a freight forwarder (e.g., FIATA Bill of Lading, FIATA Forwarder's Certificate of Receipt) or an Air Waybill (AWB) confirming acceptance of goods for international transport.
Strengths: Issued by a professional logistics provider, containing route and cargo data.
Weaknesses: Like CMR - they confirm dispatch, not delivery. Their evidential weight is lower than a B/L issued by a shipping line.
5. IE529 Message from the Customs System
Note - IE529 is NOT proof of export. The IE529 message (release for export) only confirms that the customs office of export accepted the export declaration and released the goods. It does not confirm that the goods actually left the EU. Treating IE529 as a substitute for the export confirmation is a common mistake among exporters.
| Document | What It Confirms | Strength as Proof of Export | Risk |
|---|---|---|---|
| the export confirmation | Completion of export procedure | Full - statutory standard | Minimal |
| Bill of Lading | Loading onto vessel | Medium - as part of a set | Medium |
| CMR | Handover for road transport | Low - insufficient on its own | High |
| Delivery confirmation | Receipt by buyer | Medium - depends on form | Medium-high |
| IE529 | Release for export (not export!) | None - not proof of export | Very high |
Conditions for Using Alternative Evidence
The use of alternative proof of export is not unconditional. Based on case law and tax rulings, the following conditions must be met cumulatively:
- Objective impossibility of obtaining the export confirmation - the exporter must demonstrate that genuine efforts were made to obtain the message and that, despite these efforts, it could not be obtained. Mere passivity (taking no steps at all) does not justify resorting to alternative evidence.
- A set of documents - not a single document - tax authorities expect several mutually corroborating documents (e.g., B/L + delivery confirmation + correspondence with the forwarder), not a single isolated document.
- Documents must unambiguously confirm export from the EU - it must be clear from the documents that specific goods (identifiable by invoice number, container number, or MRN) physically left the EU customs territory.
- Authenticity and reliability - documents must not raise doubts as to authenticity. They should originate from independent parties (carrier, forwarder, customs authority) or be authenticated.
Case Law and Tax Rulings
The topic of alternative proof of export has generated substantial case law - at both EU and national level. Key positions include:
CJEU Case Law
The Court of Justice of the EU in case C-563/12 BDV Hungary Trading held that the right to the zero rate on export cannot be restricted solely because a specific document is missing, provided the exporter can demonstrate by other means of evidence that the goods actually left the EU. The Court emphasized the principles of proportionality and fiscal neutrality.
In case C-275/18 Vins, the CJEU ruled that the right to the zero rate (exemption with refund) on export applies when the substantive conditions are met - i.e. the goods actually left the EU - even if the exporter did not fulfil all formal requirements.
National Court Decisions
Supreme administrative courts in EU Member States have confirmed in numerous judgments that the catalogue of proof-of-export documents is not closed, and that an exporter may use other documents provided they unambiguously confirm export. Courts have emphasized, however, that the burden of proof lies with the exporter.
Individual Tax Rulings
National tax authorities have issued numerous rulings on alternative proof of export. The position of tax authorities tends to be more restrictive than court case law - they more frequently require the standard export confirmation as the primary evidence. Favourable rulings typically concern situations where the exporter documented genuine steps taken to obtain it and demonstrated the reasons why this was not possible.
Why the Standard Export Confirmation Is Always the Safer Option
Although EU and national law permits alternative proof of export, using it carries significant tax risk in practice. Here is why the export confirmation is clearly the better option:
- The export confirmation is indisputable evidence - it is generated by the official EU customs system (AES). The tax authority has no basis to question its authenticity or content. Alternative evidence can be challenged.
- Zero interpretive risk - with the export confirmation there is no doubt whether the document "is enough". With alternative evidence there is always a risk that the tax authority will consider it insufficient.
- No need to engage tax advisors - using alternative evidence often requires consulting a tax advisor and sometimes obtaining an individual tax ruling. This means additional cost and several months of waiting.
- MRN closure cost is low - closing an MRN costs from EUR 15, a fraction of the costs associated with alternative evidence, tax rulings, and a potential dispute with the tax authority.
- Protection in tax audits - holding the export confirmation definitively closes the question of proving export. Alternative evidence may require additional explanations and correspondence with auditors.
Practical Tips - What to Do When the Export Confirmation Is Missing
If you do not have the export confirmation and the deadline for applying the VAT zero rate is approaching, here is the recommended sequence of actions:
- Check MRN status - the procedure may be in the process of closing and the export confirmation could appear any day. See our guide: How to check MRN status.
- Contact your customs agent - your customs agent can check the status of the declaration in the AES system and determine at which stage the procedure stands.
- Commission a specialist to close the MRN - if the MRN is open due to problems in the port system, MRN closure through closemrn.com has an average filing time of 32 minutes (2h order acceptance guarantee) and costs from EUR 15. This is far cheaper and safer than relying on alternative evidence.
- In parallel, gather alternative documents - in case MRN closure proves impossible (e.g., the MRN has expired after 150 days), collect: B/L, delivery confirmation, correspondence with the buyer, forwarding documents.
- Consider an individual tax ruling - if the situation is unusual and you must rely on alternative evidence, an individual ruling from your tax authority will provide legal protection.
FAQ - Alternative Proof of Export
Is a CMR consignment note sufficient as proof of export for VAT zero-rating?
A CMR consignment note alone is generally not considered sufficient proof that goods have left the EU. CMR only confirms that goods were handed over for transport, not that they actually left the EU customs territory. However, it can form part of a set of alternative documents - combined with other evidence (e.g., delivery confirmation from the buyer). That said, obtaining the export confirmation by closing the MRN is always the safer route.
Is a Bill of Lading (B/L) accepted as proof of export?
A Bill of Lading is one of the stronger alternative proof-of-export documents, as it confirms that goods were loaded onto a vessel. Tax authorities in many rulings have accepted B/L combined with other documents as sufficient evidence. However, a B/L by itself does not prove that the goods reached a destination outside the EU - it only confirms loading. The standard export confirmation remains the safer option.
When can alternative proof of export be used?
Alternative proof of export may only be used when obtaining the export confirmation is objectively impossible or disproportionately difficult - for example, due to a customs system failure, technical problems at the customs office of exit, or unusual export circumstances. This is not a standard procedure - the tax authority may challenge alternative evidence if obtaining the standard confirmation was possible but the exporter did not pursue it.
Do I need a tax ruling to use alternative proof of export?
It is not formally required, but in practice it is highly advisable. An individual tax ruling (binding interpretation) from your national tax authority provides legal protection - if the tax authority later challenges your VAT return, it cannot impose penalties or interest provided you acted in accordance with the ruling. Without a ruling, you risk a dispute with the tax office.
How much time do I have to gather alternative proof of export?
The deadlines are the same as for the standard export confirmation. The exporter has until the filing deadline for the VAT return covering the period following the month of supply (roughly 2 months). If the exporter holds neither the export confirmation nor alternative evidence by that deadline, the supply must be reported at the standard domestic VAT rate. After subsequently obtaining proof, a correction can be filed to reclaim the overpaid VAT.
