Export Confirmation and VAT 0% -- Why Proof of Export Is Critical for Exporters

Updated: March 2026Reading time: ~7 min

Exporting goods outside the EU customs territory entitles you to apply the 0% VAT rate. The condition is having a document that proves the goods actually left. The standard document is the export confirmation message generated by the AES system (CC599C in Poland, Ausgangsvermerk in Germany, confirmation of exit in the Netherlands/Belgium).

The Export Confirmation as the Primary Proof of Export

The export confirmation message generated by the AES system is the primary document confirming the export of goods outside the EU. Under Art. 41(6) of the Polish VAT Act, an exporter applying the 0% rate must possess a document confirming export before the deadline for filing the tax return for the relevant period.

In practice, this means the export confirmation must be obtained:

Deadline 1 -- Primary

Before the deadline for filing the JPK_V7M (monthly) or JPK_V7K (quarterly) return for the period in which the export delivery was made.

Example: Export in January 2026. JPK_V7M for January is due by 25 February 2026 -- the export confirmation must be obtained by 25.02.2026.

Deadline 2 -- Extended

If the export confirmation was not received by Deadline 1, the exporter may declare the supply in the following period, provided the export confirmation is obtained before the filing deadline for that period (Art. 41(7) Polish VAT Act).

Example: No export confirmation by 25.02.2026 -- the export can be declared in the February return if it is obtained by 25.03.2026.

Missing Export Confirmation for Both Deadlines

If the export confirmation is not obtained before either deadline, the exporter is required to apply the domestic 23% VAT rate in the return for the delivery period (Art. 41(8) Polish VAT Act).

Alternative Documents -- Art. 41(6a) Polish VAT Act

The export confirmation is not the only document that can prove export. The catalogue of evidence is open under Art. 41(6a) of the Polish VAT Act. This means the exporter may also prove export using other documents, provided they unambiguously confirm the physical departure of goods from EU territory.

Admissible alternative documents (confirmed by individual tax rulings and administrative court jurisprudence):

Third-country customs documents -- e.g., import SAD confirming clearance at the buyer's end
Transport documents with delivery confirmation -- CMR, B/L, AWB with proof of receipt
Delivery confirmation from the buyer in the third country
Carrier Track & Trace documents confirming delivery
Port system confirmation of vessel loading (e.g., from Portbase, DAKOSY)
Bank documents confirming payment for goods delivered to a third country (as supplementary evidence)

Note: Alternative documents should be used only when obtaining the export confirmation is impossible or excessively difficult. Always try to obtain the export confirmation first -- it is the most widely accepted proof of export.

VAT Return Correction After Late Receipt of the Export Confirmation

If the exporter applied the 23% rate due to a missing export confirmation and subsequently obtained proof of export, they have the right to correct the VAT return under Art. 41(9) of the Polish VAT Act.

The correction involves:

Filing a corrected JPK_V7M/K return for the period where the supply was declared at 23%
Declaring the supply at the 0% rate
Recovering the difference (overpaid VAT)

Correction deadline: 5 years from the end of the calendar year in which the tax payment was due (Art. 70(1) Polish Tax Ordinance).

Example: Export from January 2026 -- VAT payment deadline 25.02.2026 -- correction available until 31.12.2031.

What Does a Missing Export Confirmation Mean for Your Business?

Scenario 1: Export confirmation arrives on time

Standard situation. You apply the 0% VAT rate in the return for the delivery period. No additional action needed.

Scenario 2: Export confirmation arrives late (in the following period)

You declare the export in the return for the following period. No correction needed, but the delayed settlement may affect cash flow.

Scenario 3: No export confirmation -- must charge 23%

You charge 23% VAT. After later obtaining the export confirmation, you file a correction. Meanwhile, the VAT payable is “frozen” -- for large transactions this can be a significant amount.

Scenario 4: Export confirmation never arrives

If you cannot obtain the export confirmation or any other proof of export, the 23% rate remains final. The lost VAT becomes a cost to the exporter.
