For companies undergoing a transfer pricing audit, the process is not merely a technical review carried out within the scope of a tax inspection. This process covers the evaluation of whether transactions with related parties, such as the sale of goods, services, financing, licensing, management support or intra-group cost sharing, are in line with economic reality and the arm’s length principle. For this reason, during the audit process, the company’s accounting records, agreements, pricing policies, transaction rationale and supporting analyses are reviewed as a whole.
In this content prepared for STB CPA Turkey, the objective is to explain which stages companies may encounter during the audit process, which documents may be requested, which risks may come to the forefront and how companies should prepare against potential sanctions. Audit preparation is especially critical for multinational structures, group companies, businesses working with foreign related parties and companies with regular intra-group transaction volumes.
What Is a Transfer Pricing Audit?
A transfer pricing audit is a tax-focused review process that evaluates whether transactions between related parties are consistent with the conditions that would apply between independent companies. The main objective of this audit is to determine whether companies transfer profits to different countries, group companies or more advantageous tax positions through transactions conducted with related individuals or entities. Sale and purchase of goods, service invoices, royalty payments, financing transactions, management services and cost-sharing arrangements may be evaluated within this scope.
The audit does not only assess whether the price has been determined correctly; it also analyzes the commercial rationale of the transaction, whether the service was actually received, the functions performed by the parties, the assets used and the risks assumed. Therefore, companies must be able to document not only the transaction amounts but also the economic rationale behind these amounts. STB CPA Turkey can support companies in this process by evaluating their existing related-party transactions and helping identify risk areas before the audit.
Why Is a Transfer Pricing Audit Conducted?
A transfer pricing audit is conducted to allow the tax authority to verify whether the tax base has been calculated correctly in intercompany related-party transactions. In particular, situations such as applying prices between group companies that differ from market conditions, shifting profit to low-tax jurisdictions or concentrating expenses on the company in Türkiye may increase audit risk. Within this scope, the audit aims to determine whether the company’s commercial transactions are compatible with actual economic conditions.
The purpose of the audit is not limited to identifying tax loss. Assessing whether companies’ transfer pricing policies are sustainable, documentable and defensible is also an important part of the process. Therefore, document management, method selection, benchmark comparisons and the consistency of intra-group policies come to the forefront during audits. A properly prepared transfer pricing structure enables a company to take a stronger position during the tax inspection process.
What Are the Reasons for Being Subject to a Transfer Pricing Audit?
The reasons why companies may be subject to a transfer pricing audit can vary. High-volume transactions with related parties, regular service or goods transactions with foreign group companies, reporting low profitability compared to sector averages, continuous loss declarations or the continuation of transactions that were criticized in previous periods are among these reasons. The tax authority may evaluate such indicators within the scope of risk analysis and include companies in an inspection.
Transaction volume is not the only factor that increases audit risk; the nature of the transactions is also important. For example, transactions such as management services, consultancy invoices, royalty payments or intra-group financing often require more detailed documentation and explanations. In such transactions, it must be clearly demonstrated that the service was actually provided, which method was used to determine the pricing and whether similar conditions would arise between independent parties. Therefore, companies should evaluate the reason for audit not only as a “high-value transaction” but together with the risk profile of the transaction structure.
Intensity of Related-Party Transactions
The intensity of transactions with related parties is one of the main factors that increases audit risk. If there are regular transactions between group companies, such as the sale and purchase of goods, service invoices, financing arrangements, brand usage fees or cost sharing, the tax authority may examine more closely whether these transactions comply with market conditions. Especially if related-party transactions represent a high share of the company’s turnover, the applied prices must be supported by commercial rationale. At this point, keeping documents such as agreements, invoices, service evidence, cost allocation tables and pricing methods in an organized manner provides defensibility during the audit for related-party transactions.
Arm’s Length Principle Risks
One of the most commonly assessed issues in audits is whether related-party transactions comply with the arm’s length principle. If the price applied by the company in its related-party transactions differs significantly from the price or profit margin that may occur between independent parties, this may create risk. This difference must be explained through commercial, sectoral or operational reasons. Otherwise, the tax authority may bring forward the redetermination of the transaction price and the calculation of a tax base difference. Outdated benchmark analyses, incorrect selection of comparable companies or use of a method that is not suitable for the nature of the transaction may also become points of criticism during the audit process.
How Does the Transfer Pricing Audit Process Proceed?
The transfer pricing audit process generally begins with requests for information and documents. The tax inspector or the relevant audit unit may request explanations, reports, agreements, invoices, accounting records and supporting documents related to the company’s related-party transactions. At this stage, it is important for the company to respond quickly, consistently and based on documentation. The initial information provided may determine the direction of the audit, so incomplete or contradictory explanations may lead to more detailed questioning in later stages.
As the process progresses, the audit team evaluates the company’s pricing policy, the selected transfer pricing method, benchmark analyses and transaction-based profitability. If necessary, additional explanations may be requested from company officials, accounting records may be detailed and intra-group transaction flows may be examined. If any non-compliance is identified at the end of the audit, tax assessment, late payment interest or penalty risk may arise. For this reason, companies should not approach the audit process merely as document submission, but as a controlled and strategic defense process.
Information Request Process
The information request process is one of the most critical initial stages of the audit. At this stage, the company may be asked to provide a list of related parties, transaction types, amounts, agreements, pricing policies, accounting records and supporting documents. The company’s responses must be consistent with its internal records, declarations and financial statements. Providing incomplete information or preparing documents late may cause the audit team to approach the company’s transfer pricing structure with greater suspicion. Therefore, before responding to information requests, documents should be reviewed for consistency and explanations should be prepared with technical support.
Review of the Transfer Pricing Report
During the audit process, the transfer pricing report is one of the main documents showing how the company justifies its related-party transactions. The report should include the company profile, group structure, transaction types, functional and risk analysis, method selection, benchmark comparisons and result evaluations. The audit team checks whether the analyses in the report are compatible with transaction reality. In particular, the appropriateness of the selected method, the currency of the benchmark data used and the consistency of the results with the company’s financial performance are evaluated. Reports prepared superficially or lacking sufficient transaction-based explanation may weaken the defense position during the audit.
Which Documents Are Requested During the Audit Process?
Documents requested during a transfer pricing audit may vary depending on the nature of the company’s related-party transactions. However, in general, the annual transfer pricing report, related-party agreements, invoices, accounting vouchers, evidence regarding services received, price calculation tables, benchmark analyses, group policies and financial data are reviewed. For companies working with foreign related parties, group structure, parent company documents and information within the scope of country-by-country reporting may also come into question.
The mere existence of documents is not sufficient; they must be consistent with each other, up to date and capable of explaining the transaction reality. For example, if there is a management service invoice, it must be documented by whom, within what scope, during which period and for what benefit this service was provided. Similarly, if there is cost sharing, the allocation key must be explained rationally. Documents that may be requested during the audit process can generally be grouped under the following headings:
| Document Type | Importance in the Audit |
|---|---|
| Transfer pricing report | Enables transactions to be explained through method and benchmark analyses |
| Related-party agreements | Shows the legal and commercial framework of the transaction |
| Invoices and accounting records | Reveals how the transaction is reflected in financial records |
| Service evidence | Supports the reality of the service received |
| Benchmark analyses | Shows the compatibility of the price or profit margin with market conditions |
Transfer Pricing Report and Benchmark Analyses
The transfer pricing report and benchmark analyses are documents that directly affect the company’s defense position during the audit process. The report should not be a generic text prepared only to meet a legal obligation. Transaction types, the functions of the parties, assets used, risks assumed and the rationale for the selected method must be clearly presented. In benchmark analyses, it is important to select comparable companies correctly, use current financial data and explain outlier results. Weakly prepared analyses may lead to the reassessment of pricing during the audit.
Related-Party Agreements and Invoices
Related-party agreements and invoices are key documents that show the legal and commercial basis of the transaction during an audit. Agreements should clearly specify the scope of services, pricing method, payment terms, responsibilities of the parties and transaction period. Invoices must be consistent with agreement provisions, accounting records and the actual service flow. Especially in transactions such as consultancy, management support, brand usage or technical services, the existence of an invoice alone may not be considered sufficient. Correspondence, reports, meeting records or output documents showing that the service was actually received are also important for defense purposes.
What Risks Await Companies in a Transfer Pricing Audit?
The main risks awaiting companies in a transfer pricing audit include pricing not being found arm’s length, lack of documentation, inability to prove the reality of the service, incorrect method selection and intra-group policies not being aligned with the economic conditions of the Turkish company. Companies that report low profitability, continuously declare losses or make high-value payments to related parties may face more detailed questioning. These inquiries focus not only on the transaction amount but also on the commercial necessity of the transaction.
A significant portion of the risks should be managed during the preparation period before the audit begins, not once the audit has started. Companies must create strong transaction-based documentation, periodically review their pricing policies and keep benchmark analyses up to date. Otherwise, attempting to produce documents retrospectively during the audit both causes loss of time and weakens the credibility of explanations. Therefore, transfer pricing risk is a strategic issue that should be addressed not only by the tax department but also together with finance, accounting, legal and senior management.
Incomplete or Incorrect Documentation
Incomplete or incorrect documentation is one of the most common risks encountered in transfer pricing audits. Even if the company has a report on related-party transactions, this report may not provide a strong defense in an audit if it does not sufficiently explain the transaction reality. Missing agreements, outdated benchmark analyses, absence of service evidence or inconsistencies between invoices and accounting records may become points of criticism. Such deficiencies lead to questioning of the economic basis of the transaction. Therefore, it is a healthier approach for companies to create documentation when the transaction occurs, not only at year-end.
Penalty Risks and Tax Inspection Findings
If findings against the company arise as a result of a transfer pricing audit, penalty risks may come into question. If the tax authority determines that related-party transactions are not arm’s length, it may calculate a tax base difference and make a tax assessment based on this difference. Accordingly, late payment interest and tax loss penalties may arise. In addition, failure to submit missing documents or fulfill obligations on time may increase irregularity risk. Therefore, during the tax inspection process, the company must manage both its technical explanations and document structure consistently.
What Sanctions May Be Applied as a Result of the Audit?
If it is determined as a result of a transfer pricing audit that transactions are not arm’s length, the tax authority may reassess the tax base declared by the company. In this case, the difference considered to arise from the related-party transaction may be added to corporate income and additional tax assessment may come into question. Late payment interest may be added to the assessed tax and, if the relevant conditions are met, a tax loss penalty may be applied. If documentation obligations are not fulfilled, irregularity penalties may also be taken into consideration.
Sanctions may not be limited to financial consequences. Audit findings may cause the company to be monitored more closely in subsequent periods, face additional document requests for similar transactions or be required to restructure its intra-group pricing model. Therefore, it would not be accurate to view the audit result only as a tax burden related to past periods. Establishing a sustainable transfer pricing policy reduces the likelihood of facing similar risks in future audits.
How Should Companies Prepare for a Transfer Pricing Audit?
Preparation for a transfer pricing audit should not be a process that starts after the audit letter is received. Companies should monitor their related-party transactions during the year and regularly track transaction types, amounts, pricing methods and supporting documents. It is especially important to provide transaction-based explanations for intra-group services, financing transactions, royalty payments and sale and purchase of goods. For each transaction, the commercial rationale, pricing method and document set should be ready.
During the preparation process, it should be checked whether the company’s transfer pricing policy is aligned with local legislation, group policies and the actual transaction flow. Benchmark analyses should be updated at regular intervals, agreements should reflect current conditions and accounting records should be consistent with transaction explanations. At this point, STB CPA Turkey can support companies in pre-audit preparation, documentation control, benchmark analysis review and process management by analyzing their existing risks.
Proactive Documentation Preparation
Proactive documentation preparation plays an important role in reducing companies’ audit risk. Preparing documents related to related-party transactions long after the transaction has taken place may create difficulties in explanation during the audit. Therefore, agreements, invoices, service evidence, calculation tables and method rationales should be archived regularly. A proactive approach does not only mean collecting documents; it also requires recording the commercial reason, economic benefit and pricing rationale of the transaction. This structure enables the company to provide more consistent and defensible explanations during the audit process.
Keeping Benchmark Analyses Up to Date
Keeping benchmark analyses up to date is one of the core elements of transfer pricing defense. Market conditions, sector profitability, foreign exchange effects, supply chain changes and intra-group business models may change over time. Therefore, assuming that a benchmark analysis prepared in previous years remains valid for every period may be risky. Companies should regularly review comparable company sets, financial data and the suitability of the selected method. Updated analyses help demonstrate during the audit that pricing is aligned with economic reality and reduce the risk of a potential tax base difference.
