2026 National Guidelines for Writing Export Tax Refund Statements & Supplementary Documentation Requirements: Full Interpretation

Triggers for Submitting Export Tax Refund Statements

In 2026,the tax bureau’s risk control system has completed data integration with customs,the State Administration of Foreign Exchange (SAFE),and international freight forwarding platforms,refining cross-verification granularity to individual SKU parameters and pricing.After enterprises submit export tax refund declarations,any of the following situations will require them to submit a statement:

• HS code classification deviates by more than 5% from previous declarations of the same category,or is inconsistent with the classification in the tax bureau’s benchmark commodity library
• FOB declared value deviates by ±10% from the average price of the same category at the same port in the same period,with no evidence to support pricing rationality
• Break in the logistics chain of exported goods,with mismatched senders/receivers and time points in manifests,bills of lading,and domestic transport documents
• The supplier is a new trade entity,and the first invoicing amount exceeds RMB 500,000,triggering related-party transaction verification

The review result of the statement directly determines the timeliness of tax refund receipt; multiple rejections will also trigger tax audits,involving the verification of the enterprise’s export tax refund declarations over the past 3 years.

Statement Writing Standards & Adaptation to 2026 New Regulations

After the State Taxation Administration updated the export tax refund review rules in 2026,the requirements for statements have adjusted significantly compared to previous years.If enterprises still write according to old standards,the rejection rate will exceed 70%.The core differences between old and new rules are as follows:

All submitted supporting materials must be marked as "consistent with the original",affixed with the enterprise’s official seal; electronic versions must be clearly legible,and blurred or tampered materials will directly be determined as invalid declarations.

Practical Pitfall Avoidance Guide & Real Case Review

In 2026,the risk control system automatically verifies the authenticity of all supporting materials; fabricating transaction chains or tampering with documents will directly trigger credit downgrades,and the enterprise’s export tax refund declarations for the next 6 months will all undergo 100% manual review.

In March 2026,a Shanghai-based hardware tools export enterprise shipped 2 containers of non-slip manual tools to the EU,with a total value of RMB 2.15 million and an applicable refund rate of 13%,resulting in a total tax refund of RMB 279,500.The HS code selected in the enterprise’s declaration corresponds to a 13% refund rate,while the benchmark classification in the tax bureau’s system corresponds to a 9% rate,requiring the enterprise to submit a statement.The statement submitted by the enterprise only marked "classification operation error" and was rejected twice consecutively,with the tax refund withheld for over 2 months.

After the enterprise contacted Zhongshitong,the team first retrieved the product physical inspection report and communication records with the overseas purchaser,confirming that the product had a new non-slip handle design,and the old HS code did not cover this feature,so the classification deviation did not have the subjective intention to lower the tax rate.Then,they coordinated a third-party classification consulting institution to issue a classification opinion,attached to the statement,and clearly marked the tariff differences between the old and new HS codes and the legal basis for product classification.The statement passed the review within 3 working days,and the tax refund was fully received within 7 days,with no late fees or audit risks.

In practice,it is necessary to note that all explanations of abnormal items must correspond to verifiable supporting materials; avoid ambiguous expressions such as "maybe" or "approximately".For pricing deviations,provide specific data support based on dimensions such as raw material cost fluctuations,order volume discounts,and exchange rate fluctuations.

Risk Warnings & Service Support

Inappropriate writing of export tax refund statements will bring three types of direct losses: First,compliance risk: if the supplier involved in the statement has disappeared,the enterprise will be jointly required to recover the tax refund and fined 0.5 to 5 times the tax amount; Second,exchange rate loss risk: if the deviation between the declared collection amount and the declaration amount exceeds 5%,it will trigger a warning from SAFE,and the enterprise’s annual settlement quota will be reduced; Third,capital cost loss: if the tax refund is withheld for more than 3 months,based on the current 1-year LPR of 4.35%,the monthly interest loss for a RMB 1 million tax refund is approximately RMB 3,625.

Zhongshitong is headquartered in Shanghai,covering export tax refund agency services for all ports in China,familiar with the latest tax bureau review rules in 2026.It can pre-review the enterprise’s export declaration data in advance to predict common warning points such as HS code classification,price verification,and logistics matching,and prepare corresponding supporting materials in advance.If a scenario requiring submission of a statement arises,it can produce a compliant statement document within the fastest 1 working day,with a 100% declaration pass rate for cumulative service clients.For export businesses to RCEP member countries,it can also provide supporting services such as certificate of origin endorsement and tariff reduction to maximize reducing enterprises’ tax burden costs.
