Customs Audit Reveals Undeclared Royalty Payments in Turkey: Additional Duties, Penalties and Legal Remedies (2026 Updated Guide)

A Turkish customs audit discovers royalty or licence payments that were not included in customs value. Learn when royalties affect customs valuation, how additional duties and penalties may arise, and what importers and foreign licensors can do.

A Turkish customs audit may become financially significant when authorities discover that a Turkish importer has made royalty, licence, trademark, technology, patent or similar payments to a foreign supplier, parent company or another related party without reflecting those payments in the customs value of imported goods. However, the existence of a royalty payment does not automatically mean that the entire amount must be added to customs value. The legal analysis generally requires examination of the relationship between the payment and the imported goods, the contractual structure, the conditions governing the sale and the method used to calculate the royalty. If Turkish Customs determines that an amount should have been included, the consequences may extend beyond additional customs duty to import taxes, penalties, interest-related financial consequences and historical review of previous declarations.

Why Do Customs Authorities Examine Royalty Payments?

Customs valuation generally begins with the transaction value of imported goods, subject to legally required additions and adjustments. Royalties and licence fees are therefore important where they are connected with imported merchandise and satisfy the conditions for inclusion under the applicable customs valuation rules.

Customs auditors may compare customs declarations with accounting records, licence agreements, transfer-pricing documentation, bank transfers and related-party transactions.

What Types of Payments Can Create Customs Valuation Questions?

Potentially relevant arrangements may involve trademark royalties, patent licences, manufacturing technology, proprietary know-how, designs, copyrights, franchise structures, brand licences, technical rights or other intellectual-property arrangements.

The name placed on the agreement is not decisive. Customs authorities may examine the economic substance of the payment.

Are All Royalties Added to Customs Value?

No. A royalty payment should not automatically be treated as part of customs value merely because the importer pays money to a foreign rights holder.

The specific legal requirements for inclusion must be examined.

Is the Royalty Related to the Imported Goods?

One of the central questions is whether the royalty or licence fee relates to the goods being valued.

For example, a payment directly calculated by reference to sales of the imported branded goods may present a different valuation issue from a payment concerning unrelated intellectual property.

The contractual and commercial connection should therefore be examined carefully.

Is Payment a Condition of Sale?

Another central question is whether payment of the royalty or licence fee operates as a condition of the sale of the imported goods.

This can require analysis beyond the wording of the purchase invoice.

The relationship between the seller, rights holder, importer and other group companies may become particularly important.

What If the Royalty Is Paid to a Third Party?

Payment to someone other than the foreign seller does not automatically remove the customs valuation issue.

Customs may examine the relationship among the seller, licensor and importer and determine whether the payment is sufficiently connected with the sale of the imported goods.

Related Companies Require Particular Attention

Multinational corporate groups frequently separate manufacturing, intellectual-property ownership and distribution functions among different companies.

A Turkish subsidiary might purchase products from one group company while paying trademark or technology royalties to another.

Customs authorities may examine the complete structure rather than analyzing each agreement in isolation.

Review the Licence Agreement

The first major document is usually the royalty or licence agreement.

Determine what rights are licensed, which products are covered, how payments are calculated, whether the licence can be terminated independently of the supply arrangement and whether the importer could realistically purchase the goods without making the royalty payment.

Review the Supply Agreement Separately

Compare the licence agreement with the product-purchase agreement.

The contracts may contain cross-references, termination provisions, territorial restrictions or other provisions connecting the royalty with the supply of goods.

Percentage-of-Sales Royalties Need Careful Analysis

Royalties are frequently calculated as a percentage of net sales in Turkey.

The importer should identify whether the calculation concerns imported goods, domestically manufactured products or both.

A royalty calculated using total Turkish turnover should not automatically be assumed to represent an amount attributable entirely to imported goods.

Separate Imported and Domestic Products

Where the Turkish company both imports finished goods and manufactures products domestically, allocation can become particularly important.

The company should determine which products actually generate the royalty and whether imported inputs, finished products and domestic production are treated differently under the agreement.

What If the Royalty Covers Several Rights?

A single payment may cover trademarks, technical assistance, software, know-how and other rights.

The company should examine whether the agreement and accounting records allow different components to be identified reliably.

Artificial allocations created only after an audit begins can attract additional scrutiny.

Customs Audit Can Extend to Accounting Records

Customs authorities conducting post-clearance review may examine accounting entries showing royalty expenses that were not visible from the original customs declaration.

The company should reconcile customs data with its general ledger and financial statements.

Bank Transfers Can Reveal Undeclared Payments

Payments made to foreign licensors can also appear in banking records.

The importer should therefore ensure that the legal explanation for royalty transfers is consistent with customs, tax and transfer-pricing documentation.

Transfer Pricing and Customs Valuation Are Not the Same

A payment being acceptable for corporate tax or transfer-pricing purposes does not automatically determine its treatment for customs valuation.

The company should perform a separate customs analysis.

Obtain All Intercompany Agreements

For multinational groups, review supply, distribution, trademark, licence, technical-services, management-services and cost-sharing agreements together.

Customs may view the arrangements as parts of a single commercial relationship.

What If the Royalty Was Never Declared?

The first question should still be whether it was legally required to be included.

The company should not immediately accept an additional assessment merely because the royalty was absent from customs declarations.

Customs May Recalculate Historical Import Values

If authorities conclude that royalties should have been included, they may examine historical declarations within the legally applicable period.

For high-volume importers, even a relatively small valuation adjustment can produce substantial cumulative exposure.

Build a Declaration-by-Declaration Exposure Matrix

Prepare a spreadsheet identifying declaration date, imported product, invoice value, royalty basis, customs duty rate, other import taxes and potential valuation adjustment.

Do not assume that every historical import produces identical exposure.

Product Differences Matter

Some imported goods may fall within the licence arrangement while others do not.

The audit response should therefore distinguish products rather than applying one royalty percentage indiscriminately across all declarations.

Country and Tariff Treatment Can Change the Financial Effect

An increased customs value may affect different imports differently depending on tariff classification, origin, preferential treatment and applicable import taxes.

The financial calculation should therefore be declaration-specific.

Additional Customs Duties May Be Assessed

Where Customs determines that the declared customs value was understated, additional customs duties and other amounts calculated on customs value may potentially arise according to the specific import transaction.

The assessment should be checked mathematically as well as legally.

Import VAT Exposure Should Also Be Reviewed

An increase in customs value can also affect the taxable base relevant to import taxation.

The company should therefore calculate total exposure rather than focusing solely on ordinary customs duty.

Penalties Are a Separate Legal Question

An additional customs debt and an administrative penalty should not automatically be treated as the same issue.

Even if an additional amount is ultimately determined to be payable, the legal requirements supporting a penalty should be examined separately.

Incorrect Customs Valuation Does Not Automatically Mean Fraud

Royalty valuation can involve complicated contracts, related-party structures and genuine legal interpretation questions.

An incorrect declaration should not automatically be equated with deliberate customs evasion.

The company’s historical compliance process and professional advice should be preserved as evidence.

Could the Matter Become Criminal?

A valuation dispute is not automatically a criminal case. However, the risk analysis changes materially if authorities allege fabricated agreements, false invoices, concealed payments, deliberate double invoicing or other conduct potentially falling within criminal or anti-smuggling provisions.

If a criminal investigation begins, the administrative customs defense and criminal defense should be coordinated immediately.

Preserve the Original Agreements

Do not modify historical contracts after the audit begins.

If agreements were amended over time, preserve every historical version and identify the effective dates.

Do Not Backdate Documents

Creating retrospective agreements or altering historical invoices can transform an ordinary customs valuation dispute into a substantially more serious problem.

Any explanatory document prepared during the audit should be clearly identified as a current explanation.

Obtain the Customs Audit Findings

The importer should understand precisely how Customs calculated the disputed royalty addition.

Determine which agreement, accounting entry, payment or legal interpretation supports the authority’s position.

Check the Calculation Period

Historical exposure should be examined declaration by declaration, including applicable limitation rules and any circumstances that authorities claim affect those periods.

Do not accept a single aggregated figure without reviewing the underlying declarations.

Review Whether the Royalty Was Already Reflected in the Price

Another important factual issue is whether the economic amount under examination was already included directly or indirectly in the invoice price.

The same economic value should not be added twice merely because different accounting descriptions appear in corporate records.

Foreign Manufacturer Evidence Can Be Important

The foreign supplier should explain its relationship with the licensor, pricing methodology and whether sales to the Turkish importer depend on payment of the royalty.

Corporate group charts and contractual evidence may become particularly important.

Foreign Licensor Evidence May Also Be Necessary

Where the licensor is separate from the manufacturer, determine what control or influence it exercises over the supply relationship.

The factual relationship can be as important as the formal contract language.

Independent Customs Valuation Analysis May Help

Complex royalty structures often benefit from a transaction-by-transaction legal and financial analysis.

A useful report should connect contractual terms, accounting records, imported products and customs declarations rather than discussing royalties only in abstract terms.

Can the Importer Challenge the Additional Assessment?

Potentially. Once an additional customs assessment or related administrative decision is formally notified, the importer should immediately determine the applicable objection procedure and deadline.

Technical discussions with auditors should not cause formal procedural rights to expire.

Challenge the Legal Basis and Calculation Separately

An objection may involve several distinct issues: whether the royalty is includable at all, whether only part of it is relevant, whether the allocation method is correct, which imports are affected and whether the associated penalty is lawful.

Separating these issues can make the defense substantially clearer.

What If Only Part of the Royalty Relates to Imported Goods?

The importer should prepare a documented allocation methodology where legally appropriate.

Product-level sales, licence schedules, domestic manufacturing data and accounting records may help establish the amount actually connected with imported goods.

What If Customs Applies the Royalty to Every Import?

Review whether every imported product is genuinely covered by the licence.

A blanket adjustment can be disputed where the contractual and factual evidence demonstrates materially different product categories.

Review the Customs Broker’s Role

Determine what information was supplied to the customs broker before importation.

If the broker was never informed of the royalty arrangement, internal compliance procedures should be reviewed. If full information was provided, preserve the correspondence and any valuation advice received.

Foreign Supplier Contractual Liability May Arise

Where a foreign supplier represented that its pricing and documentation complied with Turkish customs requirements, the importer should review whether additional duties or penalties can be recovered contractually.

This issue becomes particularly important where the supplier and licensor structured the arrangement.

Review Indemnity Clauses

Supply and licence agreements may allocate responsibility for customs duties, taxes, penalties, professional costs and audit cooperation.

The contractual claim should be preserved while the customs dispute is ongoing.

Consider Voluntary Correction for Other Declarations Carefully

If the audit identifies a genuine problem affecting declarations outside the immediate sample, the company should evaluate available corrective mechanisms promptly.

Any voluntary action should follow a full legal analysis rather than applying the auditor’s position automatically to every historical declaration.

Review Current Imports Immediately

Do not continue filing declarations under the same valuation method without examining whether the disputed royalty treatment affects ongoing shipments.

Otherwise, potential exposure may continue increasing during the audit.

Update Customs Valuation Procedures

Once the issue is identified, create a written process requiring review of new royalty, licence, franchise and related-party agreements before imports occur.

Customs compliance should be involved whenever the commercial structure changes.

Coordinate Customs, Tax and Finance Teams

Royalty payments often cross departmental boundaries.

Legal, customs, finance, tax, transfer-pricing and procurement teams should use consistent factual information while recognizing that different legal regimes may apply different tests.

2026 Practical Defense Strategy

When a Turkish customs audit discovers undeclared royalty payments, the importer should immediately collect all licence and supply agreements, identify every affected product, determine whether the payment relates to the imported goods and whether it satisfies the applicable conditions for inclusion in customs value, reconcile payments with accounting records, examine historical declarations individually, calculate potential duties and taxes, review penalties separately and protect all available administrative and judicial remedies.

The company should also determine whether the issue is limited to customs valuation or whether allegations concerning false documentation or intentional concealment create additional criminal exposure.

Frequently Asked Questions

Must every royalty paid to a foreign company be included in Turkish customs value?

No. The applicable customs valuation conditions must be examined. The existence of a royalty payment alone does not automatically establish that the entire amount belongs in customs value.

What if the royalty is paid to a foreign parent company rather than the seller?

The relationship among the importer, seller and rights holder should be analyzed. Payment to a separate company does not by itself resolve the customs valuation question.

Can Customs examine royalties after the goods have already been released?

Yes. Royalty issues can arise during post-clearance customs audits and subsequent controls.

Can Customs assess additional duty for previous imports?

Potentially, subject to the applicable legal requirements and relevant periods. Historical declarations should be analyzed individually.

Can import VAT also increase?

Potentially. An increase in customs value can affect other amounts whose taxable base depends on the customs valuation of imported goods.

Does additional customs duty automatically mean a penalty must also be paid?

No such assumption should be made. The legal basis for the customs debt and any administrative penalty should be reviewed separately.

Can an undeclared royalty result in a criminal investigation?

A royalty valuation disagreement is not automatically criminal. Criminal risk becomes more significant where authorities allege intentional concealment, false documentation or other conduct potentially falling within criminal customs legislation.

Can the importer challenge Customs’ allocation method?

Potentially. If only part of a royalty relates to imported goods or different product groups are treated differently, a documented alternative allocation may be important.

Should the foreign supplier participate in the defense?

Often yes. The supplier or licensor may possess essential evidence concerning pricing, contractual relationships and whether payment of the royalty is connected with the sale of the imported goods.

What should the company do first?

Do not assume that an undeclared royalty automatically creates customs debt. Reconstruct the complete commercial arrangement first: identify the imported products, royalty calculation, licensor, seller, contractual relationship and payment conditions, and then determine which amounts—if any—legally belong in customs value.
