Does a Polish exporter need to know about postponed accounting when shipping to Dublin?

Not for an ordinary delivery of Union goods from Poland to Ireland, because there is no import and no import VAT; the transaction is an intra-Community supply. The scheme matters only when the Irish consignee imports goods from a third country, for example goods bought in Great Britain, and then it concerns the consignee's return, not the Polish seller.

Where in the VAT3 return is an import under postponed accounting reported?

According to Revenue's description, the value of the imported goods is entered in the separate box PA1, and the VAT due and deductible in boxes T1 and T2 of the same return. The details, eligibility conditions and exclusions must be checked directly with Revenue or a tax adviser, because OTSL does not provide tax advice.

Postponed accounting in Ireland (VAT3)

Q: Does import VAT arise on the landbridge through Great Britain?

No, provided the goods travel under a T2 transit. Union goods crossing GB under customs supervision are imported neither into the United Kingdom nor into Ireland. The VAT treatment stays intra-EU and postponed accounting is not applicable. The condition is a transit that is correctly opened and closed.

Postponed accounting lets a VAT-registered trader in Ireland account for import VAT in the VAT3 return instead of paying it at customs clearance. Output and input VAT are declared in the same return, subject to the normal deduction rules. The scheme was introduced to soften the cash-flow impact of Brexit, but it covers imports from any country outside the EU. For goods from Poland delivered by direct ferry it is irrelevant: that is an intra-EU supply, and import VAT does not arise.

What is postponed accounting and who can use it?

In a classic import, import VAT is paid at clearance and deducted only in the following return, so the business finances the tax for several weeks. Postponed accounting moves the settlement into the VAT3 return: the importer declares the VAT due on the import and, in the same return, deducts it as input VAT where entitled. For an eligible trader with full deduction rights the cash effect is neutral.

The scheme is available to VAT-registered traders in Ireland who meet the conditions set by Revenue. The value of the imported goods is declared in a separate box of the return (PA1) and the VAT itself in boxes T1 and T2. The detailed eligibility conditions, exclusions and completion rules are set by Revenue and must be checked at source, because OTSL does not give tax advice.

When are goods from Poland an import into Ireland, and when not?

Ireland is in the EU customs union. Goods from Poland delivered by direct ferry from Cherbourg, Dunkirk or Zeebrugge are an intra-Community supply: no customs declaration, no duty, no import VAT. The Irish buyer accounts for an intra-Community acquisition under the normal VAT rules, and postponed accounting does not come into it.

The landbridge through Great Britain does not change that. Union goods cross GB under a T2 transit and are imported neither into the United Kingdom nor into Ireland; the VAT treatment stays intra-EU. Postponed accounting becomes relevant only when an Irish business imports goods from a third country, for example buys in GB and brings them to Dublin, or when goods from Poland were earlier cleared for export and return to the EU as non-Union goods. The import declaration must then show an Irish importer with an EORI number and an Irish VAT registration.

VAT treatment of a delivery to Ireland step by step

Establish the status of the goods. Union goods from Poland travel as an intra-Community supply; non-Union goods or goods bought in GB are an import into Ireland. This is the first question, before anyone talks about VAT.
Match the documents to the status. Intra-EU supply: an invoice with both parties' EU VAT numbers and a CMR (the Convention on the contract for international carriage of goods by road) as proof of dispatch from Poland. Import: an import customs declaration in Ireland with the importer's details.
Name the importer in the declaration. For an import into Ireland the declaration must name a party with an Irish EORI who will account for the VAT; under DDP this is often a seller registered in Ireland, under DAP usually the buyer.
Check eligibility for postponed accounting. The importer confirms with Revenue or its adviser that it meets the conditions and that the status is active on its VAT registration.
Flag the scheme in the customs declaration. The customs agency enters the relevant indicator so that VAT is not collected at clearance; without it the VAT must be paid immediately.
Report the import in VAT3. The importer enters the value of the goods in box PA1 and the VAT in boxes T1 and T2 according to Revenue's instructions and keeps the customs documents as the basis for deduction.

Definitions

Postponed accounting: the Irish scheme for accounting for import VAT in the VAT return instead of paying it at clearance.
VAT3: the periodic VAT return filed in Ireland with Revenue; boxes T1 (VAT due) and T2 (VAT deductible) and PA1 (value of imports under postponed accounting).
Import: bringing non-Union goods into the EU customs territory with a customs declaration, duty and import VAT; a supply from Poland to Ireland is not an import.
Intra-Community acquisition: the VAT treatment of a purchase of goods from another EU member state; it applies to goods from Poland delivered to Ireland.
EORI (Economic Operators Registration and Identification): the EU identification number of a trader in customs matters, required for the importer in a declaration.
T2: transit of Union goods through a third country; on the landbridge through GB, goods under T2 are not imported into Ireland.

Checklist before delivering to an Irish consignee

Status of the goods established: Union (intra-Community supply) or non-Union (import).
Seller's and buyer's EU VAT numbers on the invoice for an intra-EU supply.
For an import: importer with an Irish EORI named in the order and in the customs declaration.
Incoterms rule in the contract consistent with who is to be the importer.
Confirmation from the importer whether it uses postponed accounting before the agency lodges the declaration.
Full set of customs documents retained for the VAT3 return and any Revenue audit.

Does postponed accounting apply to every delivery to Ireland?

No. The scheme does not apply to Union goods delivered from Poland, because there is no import and no import VAT in that relation, whether the truck takes the direct ferry or the landbridge under transit. It matters only when an Irish taxable person imports goods from a third country, and even then it depends on that trader's eligibility as confirmed by Revenue. Private individuals and businesses without an Irish VAT registration cannot use the scheme and pay VAT at clearance, unless a representative registered in Ireland acts for them. The specific tax position is assessed by Revenue or the client's tax adviser.

The OTSL role

OTSL does not give tax advice. What we do help with is what determines the treatment: we establish the status of the goods and the route, identify who is the importer in the customs declaration and prepare the clearance as part of our customs advisory service, referring open questions to Revenue or the client's tax adviser. Who pays duty and VAT under different trade terms is explained in Incoterms mismatch: DAP versus DDP. The rules for deliveries to the Republic of Ireland are described in transport to Ireland, and the lane overview is on the transport to Ireland destination page.
