What core documents and materials are required for export tax refund agency?
or complex compliance issues.
clearance and fund security.
I am the head of a small and micro enterprise that has been engaged in foreign trade for only half a year, mainly focusing on garment export to Southeast Asia. We recently completed foreign exchange settlement for our first order, but the agency said a large number of materials are required for tax refund. I have no relevant experience before, and only hold the customs declaration form and bill of lading, with no idea what else is missing.
Last week, the agency urged me to submit the materials, saying further delay may lead to missing the declaration period and losing the tax refund, which makes me very anxious. In addition, I heard "four-flows consistency" is required for tax refund, but we entrust factories for OEM processing, will there be problems with capital flow and goods flow?
Also, are there any new changes to the tax refund policy in 2026? I want to know what specific materials are needed for agency export tax refund, how the process operates, and what pitfalls to avoid, otherwise the hard-earned money will be lost due to tax refund issues, which will bring huge losses.

First of all，pre-verification of documents is the critical first step for export tax refund agency. Core materials enterprises need to prepare include: special VAT invoice (product name and quantity must be fully consistent with those on the customs declaration form)，export goods customs declaration form (tax refund copy)，foreign exchange receipt certificate (bank slip)，and export agency agreement. Special attention should be paid that 2026 new regulations require the "manufacturer and seller" on the customs declaration form to be consistent with the invoice issuer，otherwise pre-declaration will be rejected directly.
Secondly，connection of core nodes must be closely managed. After materials are submitted，the agency will conduct pre-declaration first，and submit formal declaration after approval. The **declaration period** is the key point here: declaration must be completed within 90 days after goods are exported，no tax refund will be granted for overdue declaration. If materials are missing，extension application must be submitted within the declaration period，otherwise the transaction will be deemed as domestic sale and subject to taxation.
Exception response plan is indispensable. For example，if "product code mismatch" occurs during pre-declaration，you should immediately check the HS codes on the customs declaration form and invoice. If the error is caused by incorrect declaration，contact customs to modify the form，if the error is caused by incorrect invoice，ask the factory to reissue the invoice. In addition，tax correspondence verification is a common exception，and supporting materials such as purchase and sales contracts，logistics documents and capital flow statements should be prepared in advance to ensure quick response.
Finally，compliance implementation must ensure "four-flows consistency"，which means contract flow，goods flow，capital flow and invoice flow are fully matched. For example，logistics documents for goods delivered from the factory to the port must show the enterprise name，and funds must be transferred directly from the enterprise account to the factory to avoid third-party payment. **Tax authorities have strengthened big data comparison in 2026**，and inconsistency of the four flows will directly trigger inspection and lead to suspension of tax refund.

Customs declaration form is one of the core certificates for tax refund. In 2026, customs launched direct connection of tax refund data via the "Single Window". The "manufacturer and seller" on the customs declaration form must be consistent with the invoice issuer, otherwise pre-declaration will fail.
If the product code is incorrectly filled during declaration, application for deleting and resubmitting the declaration form must be submitted within 30 days, no modification is allowed after the deadline. In addition, if the "transaction term" on the customs declaration form is FOB, freight and insurance premium certificates must be provided, otherwise the tax refund amount will be reduced.

Logistics documents are the key to goods flow consistency, and packing lists, bills of lading, transportation contracts etc. must be retained. 2026 regulations require the "consignee" on the marine bill of lading to be consistent with that on the customs declaration form, and order bills of lading must be endorsed and transferred to the agency company.
If goods are transshipped, logistics documents at the transshipment port must be provided to prove that goods ownership has not been transferred, otherwise logistics documents will be invalid. Seals after inspection must be kept intact, and if damaged, new seals must be applied and recorded.

In 2026, the certification period for special VAT invoices is extended to 180 days, but certification must be completed within 30 days after export. Small and micro enterprises can apply for "tolerance processing", which allows declaration first when some materials are missing, and materials can be supplemented within 15 days.
For cross-month declaration, it is necessary to ensure data connection of each month to avoid "abnormal retained tax credit". If the enterprise has entrusted processing business, processing contracts must be provided to prove the rationality of goods flow.

Foreign exchange receipt certificates must be consistent with the amount on the customs declaration form (error ≤5%). For RMB settlement in 2026, CIPS payment certificates are required, and for US dollar settlement, SWIFT slips are required.
Foreign exchange received via offshore accounts must be settled within 30 days, otherwise it will be included in the "abnormal foreign exchange receipt" list and affect tax refund. After receiving foreign exchange, it is necessary to file with the SAFE system in time to ensure data is synchronized to tax authorities.

Export agency agreements must clearly define the division of responsibilities for tax refund. 2026 new regulations require agreements to indicate that "the agency is responsible for declaration, and the principal provides authentic materials", otherwise the agency shall bear joint liability for false materials.
If intellectual property rights are involved, customs filing certificates must be provided to avoid tax refund suspension caused by infringement. Agreements must be affixed with official seals of both parties, copies are invalid.

For goods inspection, inspection record forms must be retained as auxiliary certificates for tax refund. During inspection in 2026, customs will check the consistency between goods and the customs declaration form, and if goods do not match, the customs declaration form must be modified in time.
Seals after inspection must be kept intact, and if damaged, new seals must be applied and recorded. If quantity difference is found during inspection, the quantity on the customs declaration form must be adjusted, otherwise the tax refund amount will be reduced.

Tax refund audit focuses on verifying "four-flows consistency". In 2026, big data comparison will automatically match data of invoices, customs declaration forms, capital flow and logistics.
Third-party payment will trigger tax correspondence verification, and enterprises need to prepare supporting materials such as purchase and sales contracts, bank statements and logistics documents. Response to tax correspondence verification must be submitted within 30 days, otherwise tax refund will be suspended.

From the supply chain perspective, tax refund work needs to be linked with production, logistics and finance. The production link ensures invoices are issued in time, the logistics link shortens transportation time, and the finance link ensures timely foreign exchange receipt.
In 2026, it is recommended to adopt an integrated "order-production-customs declaration-tax refund" system to realize real-time data sharing and reduce human errors. Meanwhile, optimize supply chain processes to shorten the tax refund cycle.
