VAT 0% on exports to the UK — conditions, documents and what to do when they are missing

Conditions for applying 0% VAT on exports to the UK — Article 41 of the VAT Act

The legal basis for the 0% VAT rate on exports is Article 41(4)–(7) of the Polish Act of 11 March 2004 on Goods and Services Tax (Journal of Laws 2004 No. 54 item 535, as amended). This provision specifies that the 0% rate applies provided that, before the filing deadline for the VAT return for a given month (or quarter), the exporter holds documents confirming the export of goods outside the EU customs territory. Export to the UK after Brexit is treated as export to a third country — the same rules apply as for export to the USA, China or any other non-EU country. This is not an intra-Community supply (0% ICS) but an export (0% under Article 41(4)).

The two-month deadline for documents — Article 41(6), with subsection (7) covering the subsequent tax period

<p>Article 41(6) of the Polish VAT Act provides that the 0% rate applies on condition that the exporter holds export evidence before the VAT return filing deadline for the period. Article 41(7) covers the subsequent tax period: if the exporter has not received export proof before that deadline, they may defer reporting the supply until the following tax period — provided the documents arrive within two months of the end of the month in which the export supply took place. If documents arrive within this two-month window: the exporter applies 0% VAT retrospectively from the month of supply, with no interest for late payment. If documents do NOT arrive within two months: the exporter must report the supply at the applicable domestic VAT rate (23% for most goods) and pay the difference. Once documents are subsequently obtained (even late), a corrected VAT return can be filed to recover the overpaid VAT.

Definition of export of goods under the VAT Act — who is the exporter

<p>Article 2(8) of the Polish VAT Act defines export of goods as the removal of goods from the territory of Poland to outside the European Union, confirmed by the customs office of exit. The exporter is the entity shown as the exporter in the customs declaration (export declaration EX-A) — i.e. the party that organises the export in its own name or on another party's behalf. In PL–UK transactions, the exporter is typically the Polish company selling goods to the UK and instructing a customs broker to file the EX-A export declaration in PUESC. Note: if the goods are sold by a Polish company but the formal exporter is the UK buyer (e.g. buying on EXW terms and arranging export itself) — the UK buyer may be entitled to any applicable VAT refund, but the Polish company must ensure it has export evidence in order to apply 0% VAT.

Alternative export evidence when IE599 does not arrive — what KAS accepts

<p>The Polish VAT Act and KAS (National Revenue Administration) interpretations allow alternative export evidence when IE599 cannot be obtained in time. Article 41(6a) of the Polish VAT Act lists documents that may substitute or supplement the IE599: (1) CMR transport document or bill of lading with confirmation of delivery outside the EU; (2) packing list with the stamp of the customs office of exit; (3) courier (DHL, FedEx) shipment confirmation with delivery confirmation to a UK address; (4) parcel tracking extract with confirmed delivery to the UK; (5) a copy of the UK import declaration (C88 or CDS declaration) confirming receipt of goods in the UK — documents provided by the UK importer or UK customs broker. KAS interpretations indicate that none of these documents is absolutely required individually — what counts is the combined documentation credibly confirming that the goods left the EU customs territory.

Complete documentation for 0% VAT on UK exports — checklist

Documentation for 0% VAT on exports to the UK must be complete and consistent — tax authorities verify that data matches across different documents (invoice value vs customs value, goods description vs HS code, sender and recipient details). Below is the full list of documents with an explanation of each document's role. Easy Clearance generates and archives EX-A declarations and facilitates the retrieval of IE599 — minimising your risk of missing documentation on the customs side.

EX-A export declaration and IE599 message — what they are and how to obtain them

<p><strong>EX-A</strong> is the electronic export declaration filed by the customs broker in the ECS (Export Control System) through the PUESC platform. It contains: exporter and recipient details, goods description and HS codes, customs value, destination country (UK), and Incoterms. Once the EX-A is filed, the customs office of exit (e.g. in Gdańsk, Warsaw or another Polish port of exit) confirms that the goods have left the EU — and generates the <strong>IE599</strong> (Customs Exit Results) message. The IE599 is sent automatically to the exporter's or customs broker's PUESC account. It is the primary export proof for 0% VAT. Easy Clearance delivers a copy of the IE599 to the client immediately after it is generated. If the IE599 is delayed (most common cause: data error or ECS system delay) — we contact the customs office of exit on your behalf. Export clearance service: from £45 to £120. <em>Prices quoted are indicative ranges — exact quote after document review.</em></p>

Commercial invoice, CMR, packing list — formal requirements

<p><strong>Commercial invoice</strong>: must contain the seller's and buyer's details, goods description (matching the HS code on the customs declaration), value and currency, and payment and delivery terms (Incoterms). We recommend including the customs reference number (MRN from EX-A) on the invoice — this makes it easier to link the invoice to the customs declaration during a tax audit.</p><p><strong>CMR</strong> (Convention on the Contract for the International Carriage of Goods by Road) or other transport document: must contain the date of dispatch, place of loading (Poland), place of delivery (UK), sender's and recipient's details, and cargo description. The original CMR or a stamped copy from the courier or driver is important export evidence, particularly when the IE599 is delayed.</p><p><strong>Packing list</strong>: a breakdown of the shipment contents with weights and dimensions — required by the customs broker to file the export declaration and useful when HMRC verifies the customs value on the UK side.</p>

UK import confirmation (CDS declaration) — additional evidence

<p>A copy of the UK import declaration (generated by the UK customs broker in the CDS system) can be provided by the UK importer or its customs broker. This document (formerly known as C88 or Entry Acceptance) confirms that the goods actually entered the UK and passed through customs clearance — it is strong supplementary evidence that KAS accepts as confirmation of departure from the EU. Easy Clearance can coordinate the retrieval of the UK import declaration copy where we act as the customs broker on both the Polish and UK sides. Prices quoted are indicative ranges — exact quote after document review.</p>

What to do when the IE599 does not arrive on time — step-by-step procedure

A missing IE599 by the deadline is the most common problem facing Polish exporters when accounting for 0% VAT on UK exports. Causes vary: a technical error in the ECS PUESC system, incorrect data in the EX-A declaration (mismatch between customs value and invoice), a delay at the customs office of exit, or a physical backlog of goods at the border. Whatever the cause — you have two months from the date of dispatch to gather export evidence. Below are the steps to take immediately when the IE599 is found to be missing.

Step 1 — check the EX-A status in PUESC and contact your customs broker

<p>Log in to PUESC (<a href="https://puesc.gov.pl/">puesc.gov.pl</a>) and check the status of the EX-A declaration: whether it shows "Released" and whether an IE599 has been generated. If the EX-A status is anything other than "Released", the declaration has a problem and the IE599 will not be generated without intervention. The most common problem statuses: "Hold" (the customs authority has held the goods for inspection), "Rejected" (a formal error in the declaration). If you use Easy Clearance — contact us directly: tel. +44 7404 091503 or WhatsApp +44 7404 091503. We monitor the EX-A status for all our clients and intervene when a problem arises. Export clearance service (PL): from £45 to £120. <em>Prices quoted are indicative ranges — exact quote after document review.</em></p>

Step 2 — gather substitute documents within the two-month window

<p>If the IE599 has not arrived within two weeks of dispatch, start gathering substitute documents: (1) ask the carrier (freight forwarder, courier) for proof of delivery to the UK address; (2) ask the UK buyer for a copy of the CDS import declaration or at least written confirmation of receipt; (3) keep the courier's parcel tracking record showing delivery to the UK; (4) ask the customs broker to check in the NCTS (New Computerised Transit System) whether the goods are covered by a T1 procedure that might explain the absence of the IE599. Submit these documents together with the VAT return for the month of sale or for the following month — KAS generally accepts a complete set of these documents as sufficient export evidence. Prices quoted are indicative ranges — exact quote after document review.</p>

Step 3 — what to do if the two-month deadline has passed without documents

<p>If the two-month deadline under Article 41(7) of the VAT Act has passed and you still have no export evidence: file a corrected VAT return for the month of supply showing the sale at the domestic 23% rate and pay the VAT difference. This does not generate interest charges provided the correction is filed before a KAS audit. Once export documents are subsequently obtained (even late), you can file a further corrected VAT return and recover the overpaid VAT — Article 41(8) of the Polish VAT Act permits this. Do not wait for a tax audit before filing the correction — the tax authority may assess interest on arrears if it discovers missing documents during an audit before you have filed the correction. Always seek advice from a tax adviser when the VAT amount involved exceeds PLN 10,000.</p>

What the current rules say

VAT 0% on exports to the UK is available to the Polish exporter provided they hold documents confirming the export of goods outside the EU customs territory — primarily the IE599 from the ECS/PUESC system — before filing the VAT return. Article 41(6) of the Polish VAT Act establishes the condition for holding documents; Article 41(7) gives two months to gather documents in the subsequent tax period: if the IE599 arrives within that time, 0% VAT applies retrospectively with no interest; if not, the exporter must report at 23% and correct the return once documents are obtained. Easy Clearance files EX-A export declarations through PUESC and monitors IE599 generation, minimising the risk of documentation gaps on the customs side.

FAQ — frequently asked questions

What documents are required for 0% VAT on exports to the UK?

The primary document is the IE599 — an electronic message from the ECS (Export Control System) in PUESC, confirming that goods have left the EU customs territory. Supplementary documents required: commercial invoice, CMR (transport document), packing list and EX-A export declaration. If the IE599 does not arrive on time, alternative export evidence is accepted: courier delivery confirmation, copies of the UK CDS import declaration, or written receipt confirmation from the UK buyer.

How long do I have to gather documents for 0% VAT on an export?

Article 41(6), with subsection (7) covering the subsequent tax period, of the Polish VAT Act gives the exporter two months from the end of the month in which the export supply took place to gather documents confirming the export. If documents arrive within this period, 0% VAT applies with no interest for late payment. If they do not arrive — the sale must be reported at 23% VAT and a corrected return filed once documents are obtained.

What is the IE599 and why do I need it?

The IE599 is an electronic message generated automatically by the ECS (Export Control System) in PUESC when the customs office of exit confirms that goods have physically crossed the EU border. It is the primary export proof required by KAS to apply 0% VAT on an export. Without the IE599 or substitute documents, you cannot prove that the goods actually left the EU.

What should I do if the two-month deadline has passed and I have no IE599?

If the two-month deadline under Article 41(7) has passed without documents, file a corrected VAT return for the month of supply showing the sale at 23% and pay the VAT difference. This does not generate interest provided the correction is filed before a KAS audit. Once export evidence is later obtained, you can file a further correction and recover the overpaid VAT. Seek advice from a tax adviser for amounts above PLN 10,000.

Is exporting to the UK after Brexit treated as an intra-Community supply?

No — from 1 January 2021 (the end of the Brexit transition period), trade with the UK is treated as export/import with a third country, not as an intra-Community supply. Article 41(4) of the Polish VAT Act applies (export, 0% with export evidence), not Article 42 (ICS, 0% with VAT-UE summary declaration). Instead of a summary declaration you need the IE599.
