As an important pillar industry of the national economy, the tax compliance of the petrochemical industry has attracted considerable attention amid an increasingly stringent regulatory environment. Currently, China's tax collection and administration reform is advancing in depth. At the central level, great focus is placed on the supervision of consumption tax on refined oil products. Multiple departments have jointly issued supporting policies to establish a full-chain supervision system, and digital means are used to deepen the application of "governing tax collection by data." The crackdown on tax-related violations and crimes is being continuously intensified, putting petrochemical enterprises at risk of a new round of systemic tax-related risk escalation.

From the perspective of industry practice, the tax risks faced by petrochemical enterprises currently exhibit distinct characteristics of typification and chain transmission. Specifically, production enterprises are frequently involved in risks of evading consumption tax through "reverse invoice alteration," i.e., falsely labeling taxable refined oil products as non-taxable chemical products for sale by changing product names. The core risks for trading enterprises lie in behaviors such as falsely issuing special VAT invoices through "name alteration, invoice passing, and mismatch." Gas stations at the retail end evade taxes by concealing income, tampering with data through technical fraud, etc. Such risks are no longer confined to a single link but spread along the industrial chain upstream and downstream. Faced with the new regulatory environment, enterprises need to accurately grasp the boundary of tax qualification of products, while focusing on ensuring the authenticity and standardization of logistics documents such as electronic waybills and weighbridge tickets to prevent regulatory inspection risks caused by information distortion. In addition, with the full implementation of digital invoices and the comprehensive application of intelligent tax control platforms, the full-chain data of enterprises' purchase, sale, and inventory has been included in real-time supervision. Therefore, improving the accounting book and voucher system and ensuring data traceability and verifiability have become the foundation for enterprises to respond to supervision and prevent risks.

The Tax Compliance Report for the Petrochemical Industry (2026) is a legal research report compiled by Huashui based on years of in-depth observation of the petrochemical industry and profound summary of experience in handling tax-related cases in the industry in 2025. It aims to reveal the current status and investigation trends of tax-related case handling in the petrochemical industry, analyze the changes in major tax-related risks of the industry, and put forward defense strategies and compliant operation suggestions, so as to provide useful guidance for petrochemical enterprises in preventing and resolving tax-related risks.
