Bank Account Attachment for Customs Debt in Turkey: What Can Foreign Companies Do? — 2026 Current Guide

Foreign companies may face electronic bank account attachment for unpaid customs debt in Turkey. Learn how to challenge the debt, payment order and attachment, and how to seek urgent release in 2026.

A foreign company importing goods into Turkey may discover that its Turkish bank account has been frozen because of an alleged unpaid customs debt. The attachment may follow an additional customs duty assessment, administrative penalty, interest calculation or post-clearance audit.

When an electronic attachment is imposed, the bank may block the company’s Turkish lira and foreign-currency balances. Payments to employees, suppliers and logistics providers may fail, while future customs operations can be disrupted.

The attachment is not necessarily final or lawful. The company may challenge the underlying customs assessment, the payment order and the attachment itself. It may also request suspension of execution, negotiate settlement or seek release of amounts that are not legally recoverable.

Urgent action is essential because customs collection procedures contain short deadlines.

How Does a Customs Bank Attachment Arise?

Customs duties and related amounts are public receivables. If the administration claims that a customs debt has not been paid within the legal period, it may issue a payment demand and begin collection under Turkish customs and public-receivables rules.

A bank account attachment generally follows an enforceable payment order that remains unpaid. In some circumstances, the administration may also take precautionary collection measures where it considers that recovery is at risk.

The bank receives an electronic attachment order and blocks funds up to the amount specified. The company may not be able to transfer money, make payroll payments or use its account until the order is lifted, reduced or satisfied.

The importer should obtain the complete collection file immediately, including the customs assessment, penalty, notification record, payment order, calculation and bank attachment notice.

Is the Bank Attachment Automatically Valid?

No. The administration must have a legally enforceable public receivable and must follow the applicable notification and collection procedures.

A bank attachment may be challenged where the underlying customs debt was cancelled, paid, time-barred or assessed against the wrong entity. It may also be unlawful if the payment order was not properly served, the amount was calculated incorrectly or the administration attached funds exceeding the legally recoverable amount.

The bank is usually required to comply with the official order unless the administration or a court withdraws or suspends it. The company should therefore challenge the correct administrative act rather than relying only on a complaint to the bank.

What Is the Difference Between the Assessment, Payment Order and Attachment?

The customs assessment establishes the alleged duty, tax, penalty or interest. The payment order demands payment within the period stated by the collection authority. The bank attachment is an enforcement measure used to collect the amount.

Each act may contain a separate legal defect. A company may challenge the original customs assessment under Article 242 of Turkish Customs Law No. 4458, contest a payment order under the applicable public-receivables procedure and seek cancellation or suspension of the bank attachment.

Challenging only the bank attachment may not resolve the underlying customs debt. Conversely, challenging the assessment may not automatically release the bank account if the collection authority continues enforcement.

The legal strategy should address every connected act.

What Is the Deadline to Challenge the Customs Assessment?

Under Article 242 of Customs Law No. 4458, an objection against a customs decision is generally filed within 15 days from lawful notification.

The company should identify the notification date, decision number, declaration and amount claimed. If the assessment concerns a separate administrative penalty, the penalty should also be challenged expressly.

If the objection is rejected, the importer may generally bring an action before the competent tax court. For many customs disputes, the judicial filing period is commonly 30 days from notification of the rejection decision, but the exact deadline must be confirmed from the decision and applicable procedural rules.

What Is the Deadline to Challenge a Payment Order?

A payment order issued under Law No. 6183 on the Collection of Public Receivables carries its own short objection period. Under current practice, the period is commonly 15 days, but the importer should verify the exact period and competent court stated on the document.

The payment-order challenge may argue that no such debt exists, that the amount was paid, that the debt is time-barred, that the wrong entity was pursued or that the payment order was not lawfully served.

The company should not assume that an earlier objection against the customs assessment automatically protects it against a later payment order. Separate deadlines must be monitored.

Can Defective Notification Cancel the Attachment?

Potentially, yes. If the customs assessment or payment order was not legally served, the company may argue that the debt did not become enforceable in the required manner.

Possible defects include delivery to the wrong legal entity, service on an unauthorised broker, use of an incorrect address, an incomplete electronic notification or failure to provide access to the decision and calculation.

Under general Turkish notification principles, actual knowledge may become relevant where the recipient learned the content despite a defect. The company should therefore establish the earliest date on which it obtained the complete decision and act immediately.

Notification records, electronic access logs, broker authorisations and corporate registration documents can be decisive.

How Can the Company Request Release of the Bank Account?

The importer should submit an urgent request to the collection authority for withdrawal, reduction or correction of the attachment where the debt was paid, incorrectly calculated or pursued against the wrong entity.

If the administration does not release the account, the company may seek judicial protection. A court application can request cancellation or suspension of the enforcement act and explain the immediate effects on the company’s operations.

The request should identify the blocked bank account, amount attached, date of the attachment, underlying assessment and specific legal defects.

If only part of the debt is disputed, the company may request release of funds exceeding the undisputed amount or release after providing acceptable security, where legally available.

Can the Company Challenge an Excessive Attachment?

Yes. An attachment should generally be connected to the amount legally recoverable.

The importer may challenge a freeze that exceeds the principal debt, interest and lawful collection costs. It should prepare an updated calculation showing payments, credits, cancelled assessments, guarantees and the balance actually due.

An attachment may also be challenged where several banks were instructed to freeze amounts that together exceed the total debt. The company should request coordinated reduction or withdrawal of excess orders.

Bank statements and attachment notices should be preserved to prove the amount blocked and any business losses caused by the measure.

Can Foreign-Currency Accounts Be Frozen?

A Turkish bank account holding foreign currency may be included in an electronic attachment. The administration and bank may apply conversion rules when determining whether the blocked balance satisfies the amount claimed.

The company should verify the exchange rate, valuation date and treatment of foreign-currency balances. An incorrect conversion may cause the bank to block more than the legally recoverable amount.

The company should also determine whether the attached account belongs to the customs debtor or to another group company. Corporate affiliation alone does not automatically make an affiliate’s funds available for a different entity’s customs debt.

What If the Account Belongs to a Different Group Company?

The administration should pursue the legal debtor and not attach the funds of an unrelated company merely because the entities share shareholders, directors, branding or a banking relationship.

A group company whose account was frozen should submit corporate registration records, tax information, bank statements, intercompany agreements and evidence showing that it did not import the goods or incur the customs debt.

If funds were held for a third party, escrowed or subject to a trust-like arrangement, the company should provide documents proving the nature of the account and beneficial ownership.

The issue may require an immediate third-party claim or court application to prevent transfer of the funds to the administration.

Can Payment, Security or Installment Stop the Attachment?

The company may ask whether payment of the undisputed amount, provision of security or an approved deferral arrangement can lead to withdrawal or reduction of the attachment.

In appropriate cases, public-receivables rules may allow installment or deferred payment upon a written request and security. Approval is not automatic and depends on the legal status of the debt and the authority’s decision.

The importer should not transfer assets or move funds merely to avoid collection. Concealing assets, making sham transfers or obstructing enforcement may create additional civil or criminal risks.

Any payment should be documented carefully and should specify whether it relates to principal duty, penalty, interest or collection costs.

Can Settlement Be Used?

Certain customs duties and administrative penalties may qualify for settlement under Article 244 of Customs Law No. 4458.

If a settlement application is timely and eligible, the company may seek a reduction of the claimed amount and an agreed payment structure. The effect on an existing bank attachment should be addressed expressly.

Settlement may not be available for every violation, particularly matters associated with serious criminal allegations or statutory exclusions. The company should also understand whether signing the settlement record waives further objection or litigation rights.

Can the Company Request Suspension of Execution?

Filing an objection or lawsuit does not automatically release a bank attachment. The importer may request suspension of execution from the competent administrative court.

The company generally must demonstrate apparent unlawfulness and serious harm that would be difficult or impossible to remedy later. Bank-account freezing can support the harm requirement where it prevents payroll, supplier payments, debt service, production or essential business operations.

The request should include bank notices, failed payment records, cash-flow evidence, employment obligations, customer contracts and proof of imminent commercial damage.

A court may distinguish between the underlying customs assessment and the later collection act. Both should be identified where necessary.

2026 Action Plan for Foreign Companies

In 2026, electronic collection systems can freeze a Turkish bank account shortly after a payment order becomes enforceable. Foreign headquarters should receive immediate alerts from the Turkish subsidiary, customs broker and bank.

The company should obtain the entire enforcement file, calculate all objection and court deadlines, separate the disputed and undisputed amounts and preserve evidence of operational harm.

It should review the customs declaration, assessment, penalty, payment order, notification, interest calculation and bank attachment together. A defect in one stage may affect the legality of the next.
