I am the head of a small and medium-sized foreign trade enterprise in Shanghai specializing in home storage products. We just completed our first sea freight export order to Los Angeles, USA last month, and now we are eager to handle export tax refund to unlock our cash flow.

However, we have never been exposed to the tax refund process before, and I was completely flustered when sorting out documents last week: there are slight discrepancies between the product model on the input VAT invoice and the marking on the customs declaration form, and the export date on the customs declaration form is 3 days different from the sailing date on the ocean bill of lading. I asked peers around but got no clear answers.

Now I am very worried that these details will lead to the rejection of the tax refund application, or even leave a blemish on our compliance record and affect our future export qualification. I want to know how I can proceed with the tax refund processing step by step, and what key details I should pay attention to avoid pitfalls?

First,conduct pre-submission document verification: you need to check the key information of 4 types of core documents one by one,including special input VAT invoice,export goods customs declaration form,ocean bill of lading,and purchase and sales contract,to ensure full consistency of the four dimensions: product name,model,quantity,and export date. If there is a model discrepancy between the input invoice and the customs declaration form,you need to immediately contact the supplier to issue a red-letter VAT invoice for write-off and reissue a correct invoice,the 3-day difference between the customs declaration form and the bill of lading date is a normal error in sea freight,and you need to keep the shipping schedule change explanation issued by the freight forwarder for future use.

Core node connection: After completing document sorting,conduct pre-declaration in the "Export Tax Refund Management" module of the Electronic Tax Bureau. The system will automatically verify the data. If any doubt is prompted,you need to correct it within 3 working days before submitting the formal declaration,after declaration,you need to bind paper documents into a book simultaneously,and keep them on file for future inspection for no less than 5 years.

Abnormality response plan: If you receive a correspondence verification notice from the tax authority,you need to provide supporting materials such as goods transportation,warehousing,and foreign exchange receipt within 10 working days. When necessary,you can entrust professional institutions such as Zhongshen to assist in replying to the correspondence verification,if the tax refund application is rejected,you need to first check the type of doubt,supplement materials for document problems,and re-enter the declaration for data problems.

Final compliance implementation: After the tax authority passes the review,the tax refund fund will be transferred to the enterprise's corporate bank account within 15-20 working days. You need to update the enterprise's export tax refund ledger simultaneously to ensure closed-loop compliance of documents,data and capital flow for each transaction.

The core prerequisite for export tax refund processing is the compliance of customs declaration form information, and you need to focus on three major fields of the customs declaration form: "export date", "commodity code" and "trade term": The export date shall be consistent with the sailing date on the bill of lading issued by the shipping company. If there is a discrepancy, you need to apply to the customs for modifying the customs declaration form, otherwise the tax authority will reject the tax refund application on the ground of "doubtful export facts"; the commodity code shall strictly correspond to the accurate code in the Import and Export Tariff Schedule.

If the code classification is wrong, it will not only lead to wrong application of tax refund rate, but also may trigger subsequent customs inspection; the trade term shall be consistent with the marks on the purchase and sales contract and the bill of lading. If it is FOB transaction, the freight and premium amount shall be marked separately on the customs declaration form, otherwise it will affect the calculation of the tax base for tax refund.

The accuracy of documents in the logistics link directly affects export tax refund processing, and you need to focus on controlling the consistency of three types of documents: ocean bill of lading, manifest, and freight forwarder bill of lading: The sailing date on the ocean bill of lading shall be consistent with the export date on the customs declaration form. If the sailing date is delayed due to container rollover by the shipping company, you need to ask the freight forwarder to update the manifest information and apply to the customs for modifying the export date on the customs declaration form in time; you need to keep the "manifest confirmation letter" issued by the freight forwarder as an alternative material to prove the export date during tax refund; if LCL shipping is adopted, you need to ensure that the cargo details on the LCL bill of lading fully match the customs declaration form and input invoice, so as to avoid information differences caused by mixed loading of LCL cargo affecting tax refund review.

Export tax refund processing shall be subject to compliance planning combined with the enterprise's tax structure. For small and medium-sized foreign trade enterprises, they can choose to entrust professional foreign trade agency companies to handle tax refund, enjoy the tax compliance resources of the agency company, and reduce their own tax risks; if an enterprise carries out both domestic sales and export business, it shall strictly distinguish between input for domestic sales and input for export, and shall not mix input invoices for deduction, otherwise it will trigger the tax authority's inspection on input tax transfer out; in addition, attention shall be paid to the tax base of export tax refund.

Under the general trade model, the FOB price is taken as the tax base, and deduction items such as freight, premium and commission shall be calculated accurately to avoid deviation of tax refund amount caused by wrong tax base.

The compliance of export tax refund processing shall be linked with the foreign exchange receipt and payment operation, and the foreign exchange receipt amount shall be consistent with the transaction amount on the customs declaration form. If there is a difference in the foreign exchange receipt amount caused by exchange rate fluctuation or commission deduction, you shall submit the "foreign exchange receipt difference explanation" and supporting materials to the tax authority within 10 working days after receiving the foreign exchange; you shall collect and pay foreign exchange through formal channels, and avoid using personal accounts or offshore accounts for illegal foreign exchange receipt and payment, otherwise you will be identified as "non-compliant foreign exchange receipt and payment" by the tax authority and your tax refund qualification will be suspended; in addition, you shall keep foreign exchange receipt slips, SWIFT messages and other foreign exchange receipt and payment vouchers as core supporting materials for tax refund review.

Export tax refund processing shall ensure the compliance of purchase and sales contracts. The contract shall clearly mark key information such as product name, model, quantity, trade term, payment method, export date, etc., and shall be fully consistent with the information on the customs declaration form, input invoice and bill of lading; if the contract is modified or supplemented, a formal supplementary agreement shall be signed, and the original copy of the supplementary agreement shall be kept as supporting material during tax refund; in addition, you shall avoid agreeing on illegal clauses such as "tax-inclusive price excluding tax refund" in the contract, otherwise you will be identified as "fraudulent trade" by the tax authority, which will not only reject the tax refund application, but also may face tax penalties.

Export tax refund processing requires the establishment of a sound document retention and ledger management system. Documents such as input invoices, customs declaration forms, bills of lading, foreign exchange receipt slips, purchase and sales contracts shall be bound into a book and kept on file for future inspection for no less than 10 years (latest regulation in 2026); an export tax refund ledger shall be established, and information such as export date, customs declaration number, tax refund amount, foreign exchange receipt date shall be recorded one by one to facilitate subsequent inspection by the tax authority; if the tax authority carries out tax refund audit, all supporting materials shall be provided within 15 working days, and no document information shall be concealed or tampered with, otherwise it will trigger the tax authority's case-filing inspection and suspend the enterprise's tax refund qualification.

Export tax refund processing shall be optimized in linkage with the enterprise's supply chain process. If the enterprise adopts the "factory direct shipment" model, it shall ensure that the date of the input invoice issued by the factory is earlier than the export date on the customs declaration form, otherwise the tax refund declaration will be delayed due to "delayed input invoice"; the document transmission process of the supply chain shall be optimized to ensure that documents such as customs declaration forms, bills of lading, input invoices are collected within 10 working days after export, so as to avoid overdue tax refund declaration caused by untimely document collection; in addition, the calculation difficulty of the tax base for tax refund can be reduced by optimizing trade terms (such as changing CIF to FOB), so as to improve the pass rate of tax refund declaration.
