China’s tax enforcement entered a markedly more data-led phase across 2025 and into 2026, with national tax authorities publicly exposing more than 560 violation cases during this period. Export rebate fraud, concealed income and false invoicing remained the primary enforcement targets, while cases in the electric vehicle (EV), lithium battery and solar sectors were disclosed for the first time, signalling an expansion of enforcement scope into emerging industries.

Recent investigation cases point to a fundamental shift in tax administration from experience-based, manual checks towards data-driven, full-chain detection methodologies. This transition significantly widens compliance exposure for enterprises with complex supply chains, multi-tiered distribution networks or cross-border operating structures. This article systematically examines the case categories now drawing regulatory attention, the technology driving broader detection capabilities, the tightening of international tax cooperation mechanisms, and the audit trends most likely to shape enforcement priorities throughout 2026.

Where Enforcement is Concentrated

Four violation categories account for the majority of publicly exposed cases, and each demonstrates how detection capabilities have widened beyond the single-enterprise review to encompass full transaction chains.

Export Rebate Fraud through Full-Chain Fabrication

Since 2025, joint action by tax, police, customs and foreign exchange authorities has exposed a series of export rebate fraud cases exhibiting a consistent closed-loop pattern. The typical modus operandi involves: shell companies issuing false invoices; operators purchasing export data and forging shipping documents; funds settled through underground banking channels; and capital ultimately routed back to the originating parties.

Tax authorities employ big data analytics to flag invoice anomalies, including agricultural product prices that deviate from market rates, missing transport invoices, and gaps between declared export volumes and actual production capacity. These red flags trigger coordinated investigations working with customs authorities, banking institutions and freight forwarders to establish the factual basis for enforcement action. In 2025, eight government departments jointly inspected 76,000 enterprises suspected of false invoicing and tax evasion, successfully recovering over RMB 10 billion in rebate losses.

Concealed Income and False Declarations

Evasion methods have evolved from traditional off-book operations and private account collections towards more sophisticated and concealed approaches, including public-to-private revenue diversion through third-party payment platforms. The Golden Tax Phase IV system cross-checks data from banking institutions, payment service providers and e-commerce platforms, enabling more accurate identification of suspicious patterns such as large private-account receipts or irregular public-to-private fund transfers.

Tax incentives have also become a focal point for enforcement scrutiny. The research and development (R&D) super deduction, in particular, has drawn increased attention as authorities investigate cases where eligibility conditions were fabricated or documentation was artificially constructed to claim undue benefits.

Evasion on High-Emission and Resource-Intensive Exports

Tax authorities in Hubei, Hebei, Fujian and Guangdong provinces have exposed four consolidated cases involving tax evasion on exports of high energy consumption, high pollution and resource-intensive goods. Common violation patterns include declaring taxable goods as exempt commodities, refusing to file tax returns, and exporting under another party’s customs declaration name.

These cases reflect the strategic use of tax policy instruments to push industrial structures towards greener, more sustainable production methods. This enforcement priority is expected to remain in focus throughout 2026 as China continues to pursue its environmental and carbon-reduction objectives.

Cross-Border Related-Party Transactions

Cross-border structures drew particular regulatory attention over the past year. Under Article 45 of the Enterprise Income Tax Law and Article 8 of the Individual Income Tax Law, where a foreign entity in a low-tax jurisdiction is controlled by a Chinese resident and retains profits without a genuine business reason, tax authorities may treat those undistributed profits as deemed distributed and impose tax in the current period.

In 2025, tax bureaus in Shanghai, Jiangsu, Zhejiang, Guangdong, Shenzhen and Hainan publicly exposed cases involving undeclared offshore income. This signals that Common Reporting Standard (CRS) automatic information exchange has reached a phase of normalised, targeted regulation, rather than remaining a theoretical enforcement tool. The Shenzhen Tax Bureau, through systematic mapping of global corporate structures, identified groups holding profits offshore while paying only 10% withholding tax on repatriated amounts, raising the prospect of additional individual income tax underpayment assessments.

Full-Chain Detection under Golden Tax Phase IV

Tax enforcement no longer stops at a single company’s invoice review. Audits now systematically follow the industry chain, the capital chain and the logistics chain in an integrated manner.

Detection Methodology

In export rebate fraud cases, for example, customs port entry and exit data, road transport records, freight forwarder bills of lading and shipping manifests are all cross-referenced to verify whether underlying transactions are genuine. The penetration built into the Golden Tax Phase IV system leaves substantially less room for avoidance tactics such as establishing shell entities, purchasing documentation to match false invoices, and arranging false foreign exchange settlements.

System Integration and Alert Mechanisms

The system connects data in real time across multiple government databases, including banking, market regulation, social security, customs and foreign exchange administration. A logical break among a company’s four core flows — namely capital flow, invoice flow, logistics flow and contract flow — automatically triggers system alerts for further investigation.

Future Development Trajectory

Through 2026, tax authorities are expected to deploy artificial intelligence (AI) models to identify harder-to-spot risk patterns. For example, AI inference tools can estimate real production capacity from electricity consumption and logistics data, then compare these inferred figures against what a company has officially declared. This technological capability substantially reduces the effectiveness of traditional underproduction or false declaration strategies.

Deeper International Tax Cooperation

International tax cooperation represents one of the clearest and most consequential sources of enforcement pressure on cross-border structures.

Common Reporting Standard (CRS) Implementation

Under the CRS framework, China now exchanges financial account information automatically with more than 100 countries and regions, making offshore accounts and foreign asset holdings far more visible to domestic tax authorities. During 2025, several local tax bureaus issued offshore income verification notices, requiring taxpayers to conduct self-review and file supplementary returns where historical omissions were identified. Coverage is expected to widen further in 2026 to include capital gains transactions and trust structures, areas that have historically enjoyed lower levels of regulatory visibility.

Controlled Foreign Corporation (CFC) Rules

CFC provisions are embedded in both the Enterprise Income Tax Law and the Individual Income Tax Law. The definition of “control” was updated and expanded in 2023 to cover both shareholding thresholds and substantive control criteria. Groups that hold profits on a long-term basis in jurisdictions such as the British Virgin Islands (BVI), the Cayman Islands, Hong Kong or Singapore without a genuine business reason now face an elevated risk of tax assessments on deemed distributions.

Transfer Pricing and Global Minimum Tax

Transfer pricing scrutiny is tightening in parallel with other enforcement trends, with particular focus on intangible asset transfers, intra-group service fees and financing arrangements. On the global minimum tax front, China has actively participated in the OECD two-pillar framework, and a domestic top-up tax for large multinational groups may follow. This development is particularly relevant for foreign-invested enterprises assessing the potential effect on their Chinese subsidiaries and overall group effective tax rates.

Where Audits Are Heading Next

Several emerging trends point to the areas where tax disputes and compliance challenges are most likely to arise over the coming year:

• Internet platform quarterly reporting (effective October 2025) : Internet platform enterprises are now required to report operator identity and income data on a quarterly basis, significantly reducing information gaps and making concealed income and fake-order activity easier to detect through systematic data matching.
• Expansion to lesser-scrutinised taxes: Taxes that have historically received less enforcement attention, including property tax, water resource tax and environmental protection tax, are appearing in a growing number of investigation cases. This trend prompts companies to review their full taxable scope and ensure compliance across all tax categories.
• Value-Added Tax (VAT) Law transition (effective 2026) : The new VAT Law takes effect in 2026, and the transition period between old and new rules may create disputes over the timing of tax obligations, prepayment methodologies and the treatment of transitional arrangements.
• Incentive qualification life-cycle reviews: Qualifications for tax incentives, including High and New Technology Enterprise (HNTE) status, Small and Micro Enterprise relief, and Western Region Development benefits, face closer full-lifecycle review. Filing documentation, ongoing compliance metrics and substantive eligibility conditions are now subject to more consistent and rigorous checks.
• Centralised handling of major cases: The 2026 National Tax Work Conference set out plans to deepen upgraded audits of major cases, with higher-level tax bureaus handling them directly to limit potential local interference and ensure consistent enforcement standards across regions.
• Clearer distinction between errors and violations: Authorities have signalled a clearer administrative line between bona fide errors and deliberate violations. The regulatory framework now provides room for self-correction before an audit formally commences, encouraging proactive compliance rather than defensive responses.

Across 2025 and 2026, China’s tax administration has moved decisively and systematically towards a data-driven enforcement model. From export rebate fraud and violations in the electric vehicle, battery and solar sectors to concealed income arrangements and cross-border profit shifting, authorities have combined big data analytics, artificial intelligence and international information exchange mechanisms to widen their enforcement reach across tax categories, supply chains and national borders.

For foreign-invested enterprises and large domestic companies alike, this fundamental shift makes the treatment of tax incentives, related-party pricing arrangements and offshore profit structures far more visible to regulators than ever before. The era of relying on information asymmetry to support aggressive tax positions is giving way to a new environment of transparent, data-verified compliance.

Companies weighing their compliance exposure in this evolving environment can benefit from specialist advice on corporate structure, transfer pricing documentation and cross-border profit arrangements. Proactive review and remediation, rather than reactive defence, represent the most effective strategy for managing enforcement risk in China’s current tax landscape.
