Incomplete Export Tax Refund Retention Documents? These 3 Core Categories Directly Affect Refund Disbursement Speed

Core Compliance Framework for 2026 Export Tax Refund Retention Documents

In March 2026,the General Administration of Customs and the State Taxation Administration jointly issued the revised Administrative Measures for Filing Documents of Export Tax (Exemption) Refund,which clarifies mandatory format requirements for electronically retained documents,and includes exclusive filing documents for cross-border e-commerce B2B exports into the scope of verification.Different from the previous requirement of only paper archiving,the new regulation requires that the electronic documents retained by enterprises must be OCR-searchable PDF files with electronic signatures,and must be fully provided within 10 working days after the tax authority puts forward a verification request.

As a foreign trade service agency headquartered in Shanghai,we rely on a national port linkage network to assist enterprises in completing the whole-process archiving and compliance review of retained inspection documents.In response to the electronic signature requirements for RCEP member states’ certificates of origin and the retention standards for EU anti-dumping duty exemption documents adjusted in the 2026 new regulations,we complete pre-verification in advance to avoid refund delays caused by inconsistent documents.

I.List of Four Core Categories of Retained Inspection Documents

According to the latest 2026 policies,export tax refund retention documents shall cover the entire transaction chain.The following are the four mandatory categories of documents and compliance requirements:

Common Compliance Risks and Avoidance Suggestions

• Electronic documents are not stored as required: only WeChat screenshots and unencrypted image files are retained,which cannot be retrieved by OCR during tax authority verification,and will be directly determined as failing to retain documents in accordance with regulations
• Goods description on the declaration form is inconsistent with the invoice: some enterprises simplify the goods description on the declaration form to "hardware tools" for simplified declaration,but the invoice indicates specific models,leading tax authorities to question the authenticity of the goods category
• Missing retention of foreign exchange receipt vouchers: for forward foreign exchange collection projects,if the bank’s forward foreign exchange settlement agreement is not retained,the tax authority will suspend the tax refund until the complete foreign exchange receipt certificate is provided
• Endorsement of certificate of origin does not comply with the 2026 new regulations: certificates of origin for RCEP member states shall be electronically signed by the authorized institution of the exporting country,and paper endorsement versions are no longer recognized
• Incomplete logistics documents: only copies of bills of lading are retained,and dock receipts and freight agency contracts are not obtained,which cannot prove the full process track of the actual exit of goods

Practical Case: Refund Delay Caused by Incomplete Retained Documents and Rectification Plan

In 2025,Mr.Deng,the head of a hardware export enterprise in Shanghai,exported 1.2 million US dollars worth of hand tool sets to the EU.The tax authority suspended the tax refund because he did not retain the electronically signed version of the dock receipt,involving a refund amount of 186,000 yuan.

After receiving the entrustment,we immediately guided Mr.Deng to contact the freight forwarder to obtain the electronically signed file of the 2026 new version of dock receipt.At the same time,we checked the goods description information on the declaration form and the sales invoice,supplemented the specific models in the invoice to the remark column of the declaration form,and completed the correction of the declaration data.Within 3 working days,the tax authority completed the review,the refund funds were fully received,and no additional late fee was incurred.

The core lesson of this case is that enterprises often pay attention to core documents such as declaration forms and invoices,but ignore the retention of documents for the whole logistics chain,and in the 2026 new regulations,logistics documents have become one of the key points of tax authority verification.

Compliance Details to Be Focused on in 2026

For different export markets,the requirements for retained inspection documents are different: for RCEP member states,the electronic verification link of the certificate of origin shall be additionally retained; for the US market,the AMS declaration receipt of US Customs shall be retained; for the Middle East market,the entry certification documents after customs clearance of goods shall be retained.

In addition,tax authorities will strengthen the verification of enterprises declaring in different places in 2026.If an enterprise declares customs at Shanghai port but declares tax refund in Shenzhen,it shall additionally retain the linkage verification certificate of different ports to ensure the full traceability of documents.

Risk Warning: Penalty Standards for Failing to Retain Documents as Required

According to the revised implementation rules of the tax collection and administration law in 2026,for enterprises that fail to retain export tax refund inspection documents as required,the tax authority will order them to make corrections within a time limit,and impose a fine of more than 2,000 yuan and less than 10,000 yuan; if the circumstances are serious,a fine of more than 10,000 yuan and less than 50,000 yuan will be imposed,which will also affect the enterprise’s tax credit rating,resulting in a reduction of more than 30% in the subsequent tax refund review pass rate.

If an enterprise intentionally conceals or tampers with retained documents,it will be identified as defrauding export tax refund,and will be fined more than 50% and less than 5 times the amount of defrauded tax refund,and even be held criminally liable.
