Post-Clearance Audit in Türkiye: Is the Notification Period Three Years or Ten?

Turkish customs may notify duties that were never collected or were under-collected within three years of the date the customs obligation arose, and no longer. That is Article 197(2) of Customs Law No. 4458, and it is the answer to the question most importers ask when a post-clearance audit notice arrives. The ten years that circulates alongside it is a record-retention period from company law, not a limitation period — but there are two situations, both written into the Law, in which the three years is not the outer limit.

Where the period starts, what suspends it, how the audit is regulated and what deadlines begin once the assessment is served — alongside our guides to customs duty in Türkiye and to importing goods into Türkiye.

When Does the Three-Year Period Start, and for Which Debt?

Article 197(1) requires customs duties to be notified to the obligor immediately after assessment. Article 197(2) then addresses the post-clearance case directly: notification of duties determined, as a result of inspections carried out, never to have been collected or to have been collected short — or which could not be notified in the ordinary way — is made within three years of the date the customs obligation arose.

Two consequences follow. The period runs from the date the obligation arose, not from the audit or the report; for free circulation and partial-relief temporary importation, Article 181(1) fixes that date as the date of registration of the customs declaration. And because each declaration has its own registration date, the period is counted declaration by declaration. An audit opened in 2026 across a 2021–2025 book will, on ordinary principles, reach demands only on the declarations registered inside the three years preceding notification.

Article 197(3) closes a gap that is easy to miss: where the duty shown by the declarant equals the amount calculated by the administration, release of the goods takes the place of notification. That is what makes an unremarkable, cleared import a completed notification rather than an open one.

Article 197(5) completes the sequence at the other end: duties notified under the article become final on the expiry of the Article 242 objection period or the period for applying to the administrative courts, where neither is used.

Where Does the “Ten Years” Come From?

The ten-year figure is real but belongs to a different obligation. Article 82(1) and Article 82(5) of Turkish Commercial Code No. 6102 require every trader to keep, for ten years, its commercial books, inventories, opening and interim balance sheets, financial statements, annual activity reports, incoming commercial letters, copies of outgoing commercial letters and the documents on which the entries are based.

Customs law imposes its own, shorter obligation. Article 13 of the Customs Law requires the documents and information referred to in Article 11 to be kept five years for the purposes of customs control, and it counts that period from the end of the year in which the free circulation or export declaration was registered — with parallel starting points for end-use goods, other regimes and free zones.

Neither provision extends the notification period. They determine how long the evidence must exist, which is a different question from how long the claim survives.

When Can Customs Go Beyond Three Years?

Litigation suspends it. The sentence immediately following the three-year rule in Article 197(2) reads that the bringing of an action in connection with the event giving rise to the customs obligation suspends limitation. A short clause with real consequences: a case opened on one aspect of an import — valuation, origin, a proceeding about the same event — can hold the period open on the duty claim.

A filed criminal case replaces it. Article 197(4) provides that duty claims are pursued and collected within the prosecution and penalty limitation periods of the Turkish Criminal Code where the claim relates to an act requiring a penalty and a criminal case has been filed on account of that act, whose limitation is longer. Article 231(1) states the identical rule for administrative sanction decisions. Both conditions are cumulative, and the second is a fact capable of proof or disproof: a report sent to a prosecutor, an investigation opened, or a suspicion recorded in an inspection file is not a criminal case filed.

Where the exception does bite, the substituted period is the one in Article 66(1) of Turkish Criminal Code No. 5237: eight years for offences punishable by imprisonment of not more than five years, fifteen years for those punishable by more than five and less than twenty, with Article 66(4) directing that the upper limit of the statutory sentence governs. Under Law No. 5607, Article 3(1) and Article 3(2) carry sentences whose upper limit is five years and therefore attract eight; Article 3(7), on goods whose import is prohibited by law, carries two to six years and therefore attracts fifteen. Ten years is not one of the available answers.

One further provision keeps penalties tethered to duties. Article 231(2) provides that the limitation of administrative fines linked to a customs duty claim follows the limitation of the duties to which those fines relate. A fine that depends on a time-barred duty does not outlive it.

How Is the Post-Clearance Audit Itself Regulated?

The examination power is Article 73(1): customs administrations may, after release of the goods and in order to establish the accuracy of the particulars in the declaration, inspect the commercial documents and data relating to the import or export operations or to subsequent commercial operations, at the premises of the declarant, of other persons commercially concerned directly or indirectly, or of persons holding those documents for commercial purposes. Article 73(2) makes amendment of the declaration available after release both on the administration’s own authority and on the declarant’s request. Article 73(3) requires the declaration to be corrected on the new findings where the regime rules were applied on wrong or incomplete information — expressly without prejudice to the penalty provisions of the Law.

The procedure is filled in by the Post-Clearance and Risky Transactions Control Regulation (Official Gazette of 27 October 2008, No. 27037, as amended in 2016 and 2018), made under Articles 10 and 73 of the Law. The parts that create rights and deadlines are these:

• Advance notice. Article 10(1) requires notification at least ten days before the start date. Article 10(2) allows postponement, exceptionally, where a valid and acceptable reason is submitted in writing within one week of notification. Article 10(3) is the exception: no prior notification where it would jeopardise the purpose of the audit.
• Scope. Article 7(2) allows the audit to be limited to a subject — a sector, regime, tariff or type of duty — or to a period, and Article 9 requires the programme to state the legal basis, the persons or transactions, and the period, scope and start date. Under Article 10(4) an addition to the programme or a widening of its scope requires the inspector’s proposal, the favourable opinion of the Guidance and Inspection Board and of the General Directorate, and Ministerial approval.
• Place and hours. Article 6(2) makes the person’s own premises the rule, with the local customs office or another public office as the fallback and the head office available for multi-branch companies. Article 14(4) confines the audit to working hours unless the person accepts otherwise, and Article 14(5) requires the person or their representative to be present.
• Both directions. Article 12(1) requires the inspector to examine all matters both in the person’s favour and against it.
• Closing. Article 15(1) requires the inspector to hold a final interview on the outcome — though it allows that interview to be omitted where the audit produces no change in the amount of duty or in the obligations under customs and related legislation and the person does not ask for one. Article 15(2) requires the result to be minuted, with the place, date, subject and the names, titles and signatures of those present, and a copy given to the person. Article 16(1) requires significant findings and likely duty changes to be notified in writing, with ten days for written views and up to ten days more on written request. Article 16(2) removes those time limits where an urgent measure is needed against limitation.

Article 14(1) sets the corresponding obligation: to provide every kind of information, data, record, book and document forming the basis of the audit, and to assist with access to material generated through information systems. The boundary sits in Article 11 of the Law, which frames that duty as one limited to customs transactions.

What Arrives at the End of the Audit, and Which Clock Does It Start?

A post-clearance finding is served as an additional assessment, usually together with a penalty decision. Which penalty article applies depends on what was found, and Articles 234 and 235 both expressly cover findings made “as a result of post-release control”.

Article 234(1) applies to goods entered for free circulation or for temporary importation with partial relief. Under it, a discrepancy in the tariff elements or in the measures on which taxation is based — number, head, weight — where the duty difference exceeds five per cent, attracts a fine of three times that difference; an understated declared value attracts three times the duty difference; and a quantity difference not exceeding five per cent by sales unit, or an understatement arising from an arithmetical error, attracts half. Article 234(2) halves the exposure for inward processing, processing under customs control and full-relief temporary importation. Article 234(3) is the provision that rewards self-correction: where the discrepancy is declared by the declarant before the customs administration detects it, those penalties are applied at ten per cent. Article 234(6) sets a floor by reference to Article 241(1).

Article 235(1), which is confined to goods entered for free circulation, covers the prohibited and licence-controlled cases at much higher multiples of the customs-cleared value: four times that value under Article 235(1)(a) where import was prohibited by general regulatory act, and twice it under Article 235(1)(c) where a licence, permit or conformity document — or the information standing in its place — was required and the declaration proceeded as though it was not. Article 235(1)(e) leaves a route back, but by its own wording only for the subparagraph (c) cases: where the document or information confirming that the import was permissible is issued within the period set by the Ministry, or the relevant body reports its inspection as favourable, the fine falls to the Article 241(1) level. There is no equivalent relief for the prohibited-goods case in subparagraph (a). The lira figures in Article 235 and the Article 241 floor are nominal amounts revised annually, so current figures come from the relevant annual communiqué, not from the text of the Law.

Then the deadlines start. Article 198(1) requires payment within fifteen days of notification, extendable by thirty days on a written request made before expiry and against security, with deferment interest under Article 48 of Law No. 6183. Article 198(2) provides that an objection made to the customs administration under Article 242 interrupts the payment period, which restarts on notification of the administration’s or the court’s decision. Article 242(1) gives fifteen days from service to object to the superior authority, or to the same authority where there is none, with thirty days for the administration to decide under Article 242(2) and recourse to the administrative judicial authorities under Article 242(4). Article 244 opens a settlement route within the same fifteen days, suspends the objection and litigation period while it runs, and is unavailable under Article 244(2) where the act is connected to the smuggling offences in Law No. 5607. We set out that choice in detail in our note on customs administrative fines, objection and settlement.

Two counting rules apply throughout. Article 14(1) of the Customs Law extends a period whose last day falls on a public holiday to the end of the first working day, and Article 14(3) treats a written application sent by registered post as made on the date of posting. Where the matter reaches court, Article 7(1) of Administrative Procedure Law No. 2577 sets sixty days before the administrative courts and thirty before the tax courts.

Does a Three-Year Period Also Apply to Refunds?

The limitation rule is not one-directional. Article 211(1) requires duties paid when not legally due to be refunded, and duties assessed when they should not have been to be remitted. Article 211(2) gives the obligor three years from notification of the duty to apply — and adds that where a refund or remission situation is established as a result of control and inspection, the refund or remission is made directly, within the same period. That last sentence is the counterpart of Article 12(1) of the Regulation, which obliges the inspector to examine matters in the person’s favour as well as against it.

The limits are in the proviso that follows Article 211(1). Refund and remission requests are not accepted where the duty was paid or assessed as a result of a deliberate falsification by the person concerned, or as a result of the customs value of goods subject to trade policy measures having been increased by the obligor’s own declaration.

How Does the Period Compare With the Tax Procedure Law?

Comparison with the general tax rule explains why the two systems can reach different conclusions about one import year. Article 114(1) of Tax Procedure Law No. 213 provides that taxes not assessed and notified to the taxpayer within five years, counted from the beginning of the year following the calendar year in which the tax claim arose, become time-barred. The following paragraph suspends that period where the tax office applies to an assessment commission, and caps the suspension at one year in any event.

The general tax period is longer in years but starts later and is measured in calendar years; the customs period is shorter but starts on the day of registration and is measured per declaration. A December import and a January import of the same goods can therefore sit on different clocks — one reason a valuation or classification finding is worth reading against both bodies of rules, as our overviews of customs law and tax law work set out.

The discipline that follows is unglamorous: build the schedule of declarations with their registration dates first, mark the notification date on the assessment, and only then argue the substance. In more files than one might expect, the limitation line is drawn before the valuation line is.
