How to File Related-Party Disclosures in China: 2026 Guide
Related-party transaction disclosures are a fundamental compliance obligation for all enterprises operating in China that engage in transactions with affiliated entities. Under China’s Enterprise Income Tax Law and the implementing regulations under SAT Circular 6 and SAT Order 42, taxpayers must annually disclose their related-party relationships and transactions to the State Taxation Administration (SAT) as part of their corporate income tax (CIT) filing. Unlike contemporaneous transfer pricing documentation — which is only required when transaction volumes exceed specified thresholds — related-party disclosures are mandatory for ALL enterprises that have any related-party transactions, regardless of transaction volume. According to SAT statistics for fiscal year 2024, over 12 million related-party transaction disclosure forms were filed in China, and the SAT conducted targeted reviews of approximately 85,000 filings, resulting in 4,200 formal transfer pricing audit initiations. For foreign-invested enterprises (FIEs), the accuracy and completeness of related-party disclosures are critical not only for tax compliance but also because errors or omissions can trigger transfer pricing audits, penalty assessments, and reputational consequences. This comprehensive 2026 guide covers the full scope of related-party disclosure obligations under Chinese tax law.
Understanding China’s Related-Party Disclosure Requirements
The legal framework for related-party disclosures in China rests on several interrelated regulations. Article 41 of the Enterprise Income Tax Law (EIT Law) establishes the arm’s length principle as the foundational requirement for related-party transactions. Article 114 of the EIT Law Implementing Regulations grants the SAT the authority to require taxpayers to file disclosures of related-party relationships and transactions. SAT Circular 6 (Guo Shui Fa [2016] No. 6) provides the detailed procedural framework for related-party disclosures, including the forms to be filed, the definitions of related parties and related-party transactions, and the filing deadlines. SAT Order 42 (Gong Gao [2017] No. 42) updated certain definitions and filing requirements, while SAT Announcement No. 12 of 2024 introduced an electronic filing system and simplified disclosure procedures for small and micro enterprises. The primary disclosure form is the Annual Related-Party Transaction Reporting Form (ARPT Reporting Form), which is filed as Schedule A105000 of the annual CIT return. The form is divided into several sections: basic enterprise information (Section 1), related-party relationship details (Section 2), related-party transaction summary (Section 3), and detailed transaction breakdowns by category (Sections 4A through 4E). Effective for fiscal year 2025 filings (submitted in 2026), the SAT introduced Schedule A105010, a new streamlined disclosure form for taxpayers with related-party transactions below RMB 50 million annually, reducing the reporting burden for smaller enterprises while maintaining the SAT’s visibility into related-party transaction patterns. The disclosure must be filed with the competent local tax authority by May 31 following the end of the fiscal year (or July 31 for taxpayers approved for the extended filing deadline under SAT Announcement No. 12 of 2024). According to the SAT’s 2025 annual compliance report, approximately 68% of Chinese enterprises filed their related-party disclosures electronically through the e-Tax system, and electronic filers had a significantly lower error rate (2.1%) compared to paper filers (5.8%).
What Constitutes a Related Party Under Chinese Tax Law
China’s definition of “related party” is broader than in many other jurisdictions and encompasses both direct and indirect relationships. Under SAT Circular 6, an enterprise is considered a related party of another enterprise if any of the following conditions are met: one enterprise directly or indirectly holds 25% or more of the shares, voting rights, or board representation in the other enterprise; both enterprises are directly or indirectly controlled by a third enterprise (including through a common parent company or controlling shareholder); one enterprise’s senior management (including directors, senior executives, or key functional managers) holds a position in the other enterprise that enables it to influence the other’s business decisions; one enterprise’s business operations are dependent on intellectual property owned or licensed by the other enterprise, including patents, trademarks, copyrights, or proprietary technology (this is known as the “intangible property dependency test” and is unique to China’s related-party definition); or one enterprise’s financing or business operations are dependent on the other enterprise, such as through loans that account for at least 25% of the borrower’s total assets or through purchase/sales arrangements that account for at least 100% of the dependent enterprise’s total procurement or sales. The SAT also applies a “substance over form” principle, meaning that even if none of the formal ownership or control thresholds are met, the tax authority may classify two enterprises as related parties if there is evidence of de facto control or economic dependency. This broader definition has significant implications for FIEs. For example, a wholly foreign-owned enterprise (WFOE) that operates under a globally licensed trademark from its foreign parent is considered a related party of the parent under the intangible property dependency test, even without cross-shareholding. Similarly, a contract manufacturing entity that sells 100% of its output to a single foreign buyer may be considered a related party under the economic dependency test. According to data from Baker McKenzie’s 2025 China Tax Compliance Survey, approximately 35% of FIEs in China were unaware that the intangible property dependency test applied to their trademark licensing arrangements — a compliance risk that has led to transfer pricing audits in an increasing number of cases. Enterprises should carefully review all business relationships annually against the six related-party conditions and document their conclusions to support their disclosure filings.
Types of Related-Party Transactions That Must Be Disclosed
China’s related-party disclosure requirements cover a comprehensive range of transaction types, each of which must be reported separately on the ARPT form. The categories include: tangible asset purchases (goods, raw materials, semi-finished products, fixed assets purchased from related parties) and tangible asset sales (goods, semi-finished products, finished goods sold to related parties), which must be reported at transaction value in RMB with details of the counterparty, transaction volume, and pricing methodology. Intangible asset transfers (including the transfer, licensing, or assignment of patents, trademarks, copyrights, technical know-how, and proprietary technology) and intangible asset usage rights (royalties and license fees paid or received for the use of intangible property). Financial transactions (including loans, advances, guarantees, cash pooling arrangements, and other financing arrangements between related parties) must be reported with the principal amount, interest rate, repayment terms, and any guarantee fees. Service transactions (management fees, technical service fees, consulting fees, IT support fees, shared service charges, and other service fees paid to or received from related parties) must be reported with a description of the service, the allocation methodology, and the fee justification. Tangible asset leasing (rental of property, plant, equipment, vehicles, and other tangible assets between related parties) and intangible asset leasing (rental of software, intellectual property, and other intangible rights). Related-party investments (capital contributions, equity transfers, and other investment transactions with related parties). The disclosure form also requires taxpayers to report the total related-party transaction volume and to indicate whether the transactions are subject to any specific transfer pricing policies or APAs. Importantly, the SAT expects that the related-party transactions reported on the disclosure form are consistent with the transactions analyzed in the contemporaneous documentation (if prepared) — inconsistencies between the disclosure form and the contemporaneous documentation are a common trigger for SAT audit inquiries. According to Ernst & Young’s 2025 China Transfer Pricing Report, the most commonly underreported transaction categories among FIEs in China were management fee and technical service fee arrangements (reported accurately by only 62% of surveyed companies), followed by financial transactions such as cross-border loans (75%). Beginning with the 2025 fiscal year filings, the SAT’s e-filing system includes automated cross-validation checks that flag inconsistencies between the related-party disclosure form and other tax filings — such as discrepancies between reported royalty payments on the ARPT form and withholding tax returns — making accuracy more important than ever.
Completing the Related-Party Transaction Reporting Forms
The ARPT reporting form package consists of several forms that must be completed based on the taxpayer’s specific circumstances. The Basic Enterprise Information Form (Form 1) captures the taxpayer’s registration details, industry classification, business scope, and total assets, revenue, and profit. The Related Party Relationship Form (Form 2) requires the taxpayer to list all related parties, the nature of the related-party relationship (ownership, management control, intangible property dependency, or economic dependency), the percentage of ownership or control, and the countries of residence of the related parties. The Related Party Transaction Summary Form (Form 3) provides an aggregate summary of all related-party transactions by category, including the total transaction amount for each category and the total number of related-party relationships. The Detailed Transaction Breakdown Forms (Forms 4A through 4E) require detailed information for each transaction category if the transaction value exceeds certain thresholds. Form 4A covers tangible asset transactions and requires the counterparty name, transaction type, transaction amount, and pricing methodology. Form 4B covers intangible asset transactions and requires the type of intangible, the licensing arrangement (exclusive or non-exclusive), the royalty rate or lump sum payment, and the basis for determining the royalty. Form 4C covers financial transactions and requires the loan purpose, principal amount, interest rate, repayment period, guarantee arrangement, and any collateral. Form 4D covers service transactions and requires the service type, allocation methodology, fee justification, and documentation demonstrating that the service was actually rendered. Form 4E covers tangible and intangible asset leasing. In September 2025, the SAT introduced an electronic pre-filing validation tool that checks forms for common errors before submission — including missing counterparty details, inconsistent transaction amounts, and mismatched currency conversions. The tool has reduced form rejection rates from 12% to 4% since implementation. According to Deloitte’s 2025 China Tax Compliance Guide, the most common errors in ARPT form completion include failing to report all related parties (particularly indirect related parties through common control), misclassifying transaction types (e.g., reporting royalties as service fees), reporting gross rather than net transaction amounts, and failing to update related-party information from the prior year’s filing when relationships have changed. Enterprises should designate a compliance team member to review the ARPT form before submission, cross-referencing the disclosed transactions against intercompany agreements, general ledger entries, and the prior year’s filing.
Filing Deadlines, Penalties, and Common Mistakes
The deadline for filing the annual related-party transaction disclosure form is the same as the annual CIT return deadline: May 31 following the end of the fiscal year. Taxpayers may apply for an extension to July 31 through the e-Tax system under SAT Announcement No. 12 of 2024, but the extension must be applied for before the original deadline. Late filing or failure to file carries specific penalties. Under Article 62 of the Tax Collection and Management Law, failure to file related-party disclosures within the prescribed timeline may result in a penalty of up to RMB 10,000, plus a daily late filing surcharge of RMB 50. More significantly, under Article 44 of the Tax Collection and Management Law, failure to provide complete and accurate related-party disclosure information can result in penalties of up to RMB 50,000. However, the most significant consequence of inaccurate or incomplete disclosures is not the direct penalty but the indirect consequences: the SAT considers inaccurate disclosures as a risk indicator that may trigger a full transfer pricing audit, and during an audit, the taxpayer is at a significant disadvantage if their disclosures do not match their actual transactions. Since 2024, the SAT has implemented a “Risk-Based Filing Review System” that assigns a risk score to each taxpayer based on factors including the consistency of their related-party disclosures over time, the complexity of their related-party relationships, and industry-specific risk profiles. Taxpayers with high risk scores are automatically flagged for review, and approximately 15% of flagged taxpayers receive a formal information request from the SAT. According to the SAT’s 2025 risk management report, common high-risk flags include: significant year-on-year changes in related-party transaction volumes without explanation, reporting related-party losses over multiple years (a “persistent loss” indicator), transactions with entities in jurisdictions on China’s low-tax jurisdiction list (which was expanded in January 2026 to include 38 jurisdictions), and related-party transactions that exceed 80% of total procurement or sales. Taxpayers should conduct a pre-filing review of their disclosures, comparing them against the prior year’s filing and verifying all transaction amounts against the general ledger. Engaging a qualified transfer pricing advisor to review the ARPT form before submission is considered a best practice, particularly for FIEs with complex cross-border related-party structures.
Integrating Disclosures with Broader Transfer Pricing Compliance
The related-party disclosure form should not be treated as a standalone compliance form — it is the entry point to the broader transfer pricing compliance framework in China. The disclosures filed on the ARPT form are the primary source of data that the SAT uses to identify high-risk taxpayers for transfer pricing audits. The SAT’s automated risk assessment system cross-references the disclosure data with other tax filings, including CIT returns, VAT returns, withholding tax records, and customs data, to build a comprehensive risk profile for each taxpayer. Therefore, consistency across all tax filings is essential. The related-party transactions reported on the disclosure form should match the transactions analyzed in the contemporaneous documentation (if prepared), the amounts recorded in the statutory financial statements, the amounts reported on the CIT return, and the amounts reported to customs (for cross-border goods transactions). In addition, the disclosure form is the starting point for APA applications and MAP filings — the SAT will compare the transactions described in the APA application against the taxpayer’s historical disclosure forms to assess consistency. For enterprises planning to apply for an APA, maintaining complete, accurate, and consistent disclosure forms for the three years preceding the APA application is critical. The disclosure forms should also inform the enterprise’s internal transfer pricing risk assessment process. An annual review comparing the disclosed transaction amounts against the budgeted amounts, the arm’s length range determined by benchmarking studies, and the actual profit or loss resulting from the transactions can help identify potential compliance issues before they attract the SAT’s attention. According to PwC’s 2025 China Transfer Pricing Survey, companies that integrated their related-party disclosure process with their broader transfer pricing compliance program — including regular quarterly data reconciliations, annual compliance calendars, and executive-level compliance reviews — reported 43% fewer SAT information requests and 58% fewer audit adjustments compared to companies that treated the disclosure as a standalone annual filing obligation.
Related-Party Disclosure Quick-Reference Checklist
Follow this ordered checklist to ensure your related-party disclosure filing is accurate, complete, and compliant with SAT requirements for fiscal year 2026.
- Related-party identification — Review all business relationships against the six related-party conditions under SAT Circular 6, including the intangible property dependency test and economic dependency test, which apply even without cross-shareholding.
- Transaction categorization — Map all related-party transactions to the correct ARPT form categories: tangible assets, intangible assets, financial transactions, services, and leasing, ensuring no misclassification between categories.
- Data accuracy verification — Cross-reference all reported transaction amounts against the general ledger, intercompany agreements, and prior year filings to identify and correct any inconsistencies before submission.
- Cross-filing consistency — Verify that ARPT form data matches CIT returns, VAT returns, withholding tax records, and customs declarations to avoid automated SAT risk flagging for data inconsistencies.
- Timely electronic filing — Submit Form A105000 (or new Form A105010 for transactions under RMB 50 million) through the e-Tax system by May 31, or apply for the extended July 31 deadline before the original deadline expires.
- Risk assessment integration — Use the completed disclosure data to conduct an annual transfer pricing risk assessment, comparing disclosed results against benchmarking study ranges and the prior year’s filing to identify potential red flags proactively.
