What core required documents and compliance materials are needed for enterprises to handle export tax refund in 2026?
or complex compliance issues.
clearance and fund security.
I am the head of a small and medium-sized foreign trade enterprise in Shanghai mainly engaged in the export of mechanical and electrical products. We just expanded the EU market this year, and this is our first time to handle 2026 export tax refund.
I heard from peers before that many enterprises encounter tax refund delay or even trigger tax bureau verification due to incomplete or non-compliant materials, which slows down capital return. Now I have customs declaration forms and VAT special invoices on hand, but I still worry about missing some key materials.
We have both general trade orders and a small number of entrusted processing trade orders, so I am not sure whether there are differences in material requirements under different trade modes; in addition, we have a batch of mechanical and electrical products with lithium batteries, which belong to special categories, will we need to submit exclusive materials? Recently, the company's capital turnover is already tight, I am afraid that tax refund will be delayed due to material problems, I have been distracted even when working overtime these days, and I want to ask in detail what materials are required for export tax refund, including special requirements under different scenarios.

First of all，pre-document review should be done well，and core documents and scenario-specific exclusive materials should be distinguished: core documents must include export goods customs declaration form (tax refund copy，which must fully match the customs declaration data on the Electronic Port)，VAT special invoice (deduction copy，product name，quantity and unit must correspond one-to-one with the customs declaration form)，and foreign exchange receipt voucher (such as bank slip，which must be marked with the corresponding export order number). For different trade modes，no additional materials are required for general trade，while entrusted processing trade needs to supplement the entrusted processing agreement and VAT special invoice for processing fees，for special categories such as mechanical and electrical products with lithium batteries，UN38.3 test report and dangerous goods packaging compliance certificate are required additionally.
Attention should be paid to the connection of core nodes that all document collection and pre-declaration verification should be completed within 90 days after export. During pre-declaration，electronic document data comparison should be completed through the tax bureau system to ensure that there is no deviation in the core information of various documents. If data does not match，you need to contact the customs broker to modify the customs declaration form or coordinate with the supplier to reissue the invoice within 3 working days to avoid delaying the declaration deadline.
In terms of abnormal response plans，if you are unable to collect all materials on time due to objective reasons，you need to apply to the competent tax bureau for extension of tax refund declaration 7 days in advance，with a maximum extension of 30 days，if tax bureau verification is triggered，you need to submit original vouchers immediately to cooperate with the verification. After the final compliance is implemented，all paper and electronic documents must be retained for more than 5 years for subsequent random inspection by the tax bureau.

The customs declaration form used for export tax refund shall be an electronic printout of the export goods customs declaration form marked "for tax refund only", and the commodity code on the customs declaration form shall correspond to the commodity code on the VAT special invoice. If there is a difference in code classification, you need to apply to the customs for a classification confirmation certificate in advance to avoid abnormal tax refund review caused by code mismatch.
In addition, information such as export date, transaction method, and currency on the customs declaration form must be completely consistent with the foreign exchange receipt voucher and invoice. If the information on the customs declaration form is wrong, you need to apply for deletion and re-declaration within 15 days after export. If the time limit is exceeded, you need to provide the customs declaration form modification/cancellation confirmation issued by the customs, otherwise you will not be able to pass the tax refund data comparison.

When handling export tax refund, it is necessary to ensure that the logistics manifest data is completely consistent with the customs declaration data, including the number of goods, weight, product name, export date and other information. If LCL transportation is adopted, a copy of the sub-manifest issued by the LCL freight forwarder shall be provided, and the bill of lading number on the sub-manifest shall be consistent with the bill of lading number on the customs declaration form; if direct transportation is adopted, an electronic scan of the ocean bill of lading or air waybill (stamped with the official seal of the carrier) shall be provided.
In addition, if there are abnormal conditions such as port change and return of goods, you should timely ask the logistics service provider for the port change certificate or return customs declaration form, and submit it to the tax bureau simultaneously, so as to avoid tax refund suspension caused by inconsistency between logistics information and customs declaration form.

If the enterprise adopts the EU VAT deferral mode for export, it is necessary to additionally submit the VAT deferral filing certificate and the zero tax rate certificate issued by the EU tax authority when declaring the tax refund, to ensure that the tax refund declaration does not conflict with the VAT compliance operation. In addition, if there is a cross-border related transaction, it is necessary to provide the related transaction pricing description and contemporaneous document report to prove that the transaction price conforms to the arm's length principle, so as to avoid triggering the tax bureau's anti-tax avoidance verification due to unreasonable related transaction pricing, which leads to the suspension of tax refund.
At the same time, the issuance time of the VAT special invoice shall be within 30 days before the export date or 15 days after the export date. If it exceeds the time limit, supporting documents such as goods delivery note and transportation contract shall be provided to prove the authenticity of the transaction.

The foreign exchange receipt voucher required for export tax refund shall be the bank foreign exchange receipt slip corresponding to the export order one by one, and the slip shall clearly indicate the export contract number or the bill of lading number of the customs declaration form. If RMB cross-border settlement is adopted, the cross-border payment voucher issued by the CIPS system shall be provided to avoid the failure of tax refund review due to the inability of the foreign exchange receipt voucher to correspond to the order.
In addition, if there is advance payment for goods, the foreign exchange receipt shall be completed within 30 days after export, and the advance payment filing form shall be submitted when declaring the tax refund; if the foreign exchange cannot be received on time due to objective reasons, it is necessary to apply to the State Administration of Foreign Exchange for extension of foreign exchange receipt filing, and submit the filing certificate to the tax bureau to ensure the compliance of payment and receipt of foreign exchange for tax refund declaration.

When declaring export tax refund, a copy of the export goods sales contract shall be submitted. The buyer information, product name, quantity, transaction method, total price and other clauses on the contract shall be completely consistent with the customs declaration form and invoice. If the contract is modified or supplemented, a supplementary agreement signed and sealed by both parties shall be provided to avoid triggering tax bureau verification due to inconsistency between the contract content and the documents.
For entrusted processing trade, the entrusted processing agreement shall clearly stipulate the processing content, processing fee amount, ownership of goods and other clauses, and the agreement shall be stamped with the official seal of both parties, so as to avoid that the processing fee invoice cannot be used for tax refund due to non-compliance of the agreement. In addition, if it involves the export of intellectual property goods, the intellectual property customs protection filing certificate shall be provided to prove the intellectual property compliance of the goods.

The export tax refund declaration shall ensure the consistency of goods flow, capital flow, invoice flow and contract flow. During the review, the logical correlation between documents will be focused on, for example, the export date of the customs declaration form shall be earlier than the foreign exchange receipt date on the bank slip, and the issuance date of the VAT special invoice shall be earlier than or equal to the export date.
In addition, all tax refund documents shall be filed electronically, including customs declaration forms, invoices, foreign exchange receipt vouchers, contracts, logistics vouchers, etc. The electronic filing documents shall be stored encrypted and backed up to the cloud server, so as to avoid the failure of tax refund verification due to the loss of paper documents. If the tax bureau initiates a letter investigation, the original copies of all filed documents shall be submitted within 15 days to cooperate with the verification, and the tax refund will be suspended if not submitted within the time limit.

From the perspective of supply chain planning, the tax refund material requirements under different trade modes will directly affect the capital return efficiency. General trade has a simple set of materials, so the tax refund review cycle is usually 7-10 working days, while entrusted processing trade needs to supplement processing agreements, processing fee invoices and other materials, so the review cycle may be extended to 15-20 working days.
Enterprises should plan the capital flow in advance to avoid capital occupation caused by the difference in tax refund cycles. In addition, exclusive materials for special goods such as UN38.3 test report shall be handled 30 days in advance.
If not planned in advance, it may lead to cargo detention at the port, which will affect the export date and miss the tax refund declaration deadline. Enterprises can integrate supply chain resources, coordinate with suppliers and logistics service providers to prepare relevant materials in advance, shorten the tax refund declaration cycle and reduce capital costs.
