2026 Checklist of Required Documents for Enterprise Export Tax Refund Processing and Full-Process Practical Operation Guide

Core Framework of Documents for 2026 Export Tax Refund Processing

In 2026,customs will fully abolish paper export goods declaration forms,and electronic documents will become the only compliant vouchers for tax refund declarations.Meanwhile,the State Taxation Administration will increase the coverage of export tax refund audits to 40%,so the compliance of documents directly determines the success rate of tax refunds.The following analysis is carried out from three dimensions: basic documents,new compliance requirements,and practical operation pitfalls.

I.List of Basic Required Documents for Export Tax Refund Processing

All core documents submitted by export enterprises for tax refund declarations shall meet the requirements of "consistency between documents and certificates,and matching between all documents".A mandatory requirement for electronic signatures is added in 2026,and the specific list is as follows:

• Electronic export goods declaration form (image file pushed by the Customs Electronic Port,no paper print required)
• Special VAT invoice (the issuance date shall be within 30 days before the export date on the declaration form,and the name,quantity and unit of goods shall be completely consistent with those on the declaration form)
• Export goods detail list (including export batch,goods model,and overseas consignee information)
• Foreign exchange receipt voucher (bank slip or electronic foreign exchange receipt voucher,the difference between the received amount and the FOB price on the declaration form shall not exceed 5%)
• Recorded documents (copy of bill of lading,shipping order,purchase contract,which shall be kept for 10 years for future inspection)

II.New Document Requirements for Compliance in 2026

For different trading countries and commodity types,additional targeted documents are required for export tax refund in 2026:

• RCEP member countries: Certificate of Origin (FORM R) countersigned by the China Council for the Promotion of International Trade is required.Those who fail to complete the countersigning 7 days before shipment cannot enjoy tariff reduction or exemption
• Goods subject to anti-dumping duties in Europe and the United States: Third-party price certification documents and raw material purchase vouchers are required to prove that the products are not sold below cost
• Chemical products and electromechanical products: MSDS report and copy of 3C certification are required to ensure that the commodity classification matches the supervision conditions

IV.Practical Operation Pitfalls and Risk Warning

• Incorrect HS code classification: The customs price review system will be upgraded in 2026,and a classification deviation of more than 2% will trigger control,resulting in a 15-30 working day delay in tax refund.In 2025,we assisted a Shanghai electromechanical enterprise in adjusting the code and recovered a tax refund loss of 2 million yuan
• Missing recorded documents: Enterprises that fail to keep recorded documents will have their refunded taxes recovered and be charged a late fee of 0.05% per day.As of 2026,12% of Shanghai enterprises have been audited for this issue
• Non-standard foreign exchange receipt vouchers: The State Administration of Foreign Exchange requires that the received foreign exchange amount must be consistent with the amount on the declaration form.If the difference exceeds 5%,a statement of explanation is required,otherwise the tax refund will be rejected
• Overdue countersigning of certificate of origin: RCEP member countries will implement new review rules in 2026.Certificates of origin with overdue countersigning cannot enjoy tariff reduction or exemption,which will increase additional costs by 2%-8%

V.Exclusive Operation Tips for Shanghai Port

As a local foreign trade service provider in Shanghai,Zhongshitong can provide coordinated services for cross-location declaration at ports nationwide.In view of the relatively high inspection rate at Shanghai Port,sorting out documents in advance can reduce the probability of being placed under control:

1.Complete the pre-review of electronic documents 1 working day in advance,and correct problems such as classification errors and document inconsistencies in advance

2.For sensitive goods,prepare third-party inspection reports in advance to cooperate with customs inspection

3.Enterprises from other regions can complete declarations through Shanghai Port and enjoy the advantage of Shanghai’s customs clearance efficiency

Actual Case Analysis

Scenario: In 2025,a chemical export enterprise in Zhejiang exported polyvinyl chloride particles to the EU,was levied a 12% anti-dumping duty due to untimely countersigning of the certificate of origin,and its domestic tax refund was delayed for 3 months due to incomplete documents.

Task: Assist the enterprise in completing the tax refund declaration,re-apply for the countersigning of the certificate of origin,and recover the tax refund loss and tariff loss.

Action: Adjust the HS code classification from the original 39041000 to 39041090,supplement the recorded documents,assist the enterprise in completing the cross-location declaration at Shanghai Port,and handle the urgent countersigning of the certificate of origin.

Result: The tax refund declaration was completed within 10 days,and a tax refund of 1.2 million yuan was obtained.Meanwhile,the loss of anti-dumping duty in the EU was avoided,and the total recovered cost exceeded 3 million yuan.

The core logic of export tax refund in 2026 is "documents first,compliance priority".Enterprises should sort out documents in advance to avoid large capital occupation caused by minor problems.Relying on the resource advantages of Shanghai Port,Zhongshitong can provide full-process document review and declaration services to help enterprises complete the tax refund process quickly.
