To close a T1 procedure in Poland, the haulier must notify the arrival of the goods at the customs office of destination named in the transit declaration - regardless of which city it is located in. The NCTS2 system records the moment the goods are presented, and after checking the documents, the office confirms that transit has ended, which releases the guarantee lodged by the declarant. If the actual place of unloading differs from the office originally named, a change of the office of destination must be reported in advance.

How to prepare the process and documents
Scope of responsibility between the parties
Minimum data set for the declaration
The minimum data set required to close a T1 includes: the transit MRN, the date and code of the office of destination, the gross weight of the goods confirmed by the customs authority, and the IE044 message confirming arrival. Any discrepancy between the IE015 data and the actual state of the load must be resolved before the IE045 message releasing the guarantee is generated.

How the declaration and checks work
Operational stages from notification to release
The most common risk points and how to reduce them
The most common mistakes that lead to delays or a customs debt include: a mismatch in the goods' weight between IE015 and IE044, missing the transit closure deadline, and no confirmation that the guarantee has been released in NCTS. An internal checklist linking the documentation requirements to the responsibilities of the logistics team, accounting and the person responsible for compliance eliminates most of these problems already at the document-gathering stage.
How to stay compliant and keep clean records
Record-keeping, corrections and evidence of due diligence
Documents confirming closure of the T1 procedure - in particular the IE045 message and confirmation that the guarantee has been released - should be kept on file for a minimum of 5 years, in line with KAS requirements. If there's a discrepancy between the declaration data and the actual state of the goods, a correction should be filed without delay, together with evidence of due diligence, such as correspondence with the haulier and a goods-receipt record.
Working with a customs agency and internal audit
Working with a customs agency on an ongoing basis allows the status of T1 procedures to be monitored in NCTS in real time, and lets you respond quickly to official messages that require extra documentation. An internal audit should include at least a quarterly review of closed transit procedures, checking timeliness, the completeness of the files, and whether the guarantee settlements are correct.
Summary
In summary: when it comes to 'how to close a T1 in Poland', what matters most is running the process according to current official guidance, with a clear division of responsibility and every decision documented. This approach limits delays, reduces the number of corrections and makes it easier to defend your records during an inspection. If any requirement is unclear, check the current guidance on GOV.UK or Podatki.gov.pl.

Frequently asked questions
Where should the T1 procedure be closed in Poland?
The T1 procedure is closed at the customs office of destination named in the MRN transit declaration. In Poland these are the tax and customs offices covering the delivery location of the goods. Once the goods and documents have been presented, the office issues the IE045 message confirming closure of the transit and releasing the guarantee that was lodged.
Which document confirms that T1 transit has been closed?
Closure of the T1 procedure is confirmed by the IE045 message generated by the NCTS (New Computerised Transit System). This document releases the customs guarantee lodged by the principal and should be kept on file for a minimum of 5 years in line with KAS requirements.
Who is responsible for closing a T1 - the haulier or the customs agency?
Responsibility for correctly closing the T1 procedure lies with the principal, which is most often the customs agency that opened the transit, or a freight forwarder acting as a direct representative. The haulier is obliged to deliver the goods to the office of destination intact, while the formal closure in NCTS is carried out by the customs agency.
What are the consequences of not closing a T1 procedure on time?
Failing to close a T1 within the required deadline results in KAS opening customs-debt proceedings against the principal. This can mean having to pay the customs duties and taxes covered by the guarantee, and, in cases of gross negligence, administrative penalties. You should contact the customs office without delay and document the reasons for the delay.
How do you check T1 closure status in NCTS?
You can check the status of a transit procedure in the PUESC portal (puesc.gov.pl) by logging in with the entity's or the customs agency's account. The transit tab shows the current status of the MRN - including confirmation of the goods' arrival (IE044) and the IE045 message confirming closure of the transit and release of the guarantee.
