I am the person in charge of a foreign trade enterprise specialized in outdoor home product exports. Last month, we exported a batch of outdoor folding chairs via China-Europe Railway Express. During the pre-declaration, the tax authority notified us that the declared tax calculation base was incorrect, and the application has been stuck in the review process for nearly a week. I have looked up a large number of online materials with conflicting statements: some say the calculation should be based on the FOB price on the customs declaration form, while others say it should be based on the input VAT invoice.
The more I read, the more confused I get, and I cannot figure out what the exact basis for export tax refund is. Is the basis different under different business scenarios? Now nearly RMB 1.2 million of tax refund is pending to be credited to our account for payment to upstream suppliers. I am extremely anxious and eager to confirm the clear official basis to avoid similar mistakes next time.

The current export tax refund bases in 2026 are divided into three core tiers. The first tier covers upper-level laws and the latest normative documents issued by the State Taxation Administration. The second tier refers to the document requirements corresponding to different business scenarios. The third tier is the specific implementation standards for tax calculation and accounting. All declaration operations must be completed within this framework.
In the pre-document review stage，all documents that can be used as tax refund bases must match the real business background. Four types of core documents are indispensable: export customs declaration form，special input VAT invoice，foreign exchange collection certificate，and export contract. It is required to verify in advance that the product name，quantity，and unit of measurement on all documents are completely consistent，so as to avoid logical conflicts that directly trigger declaration interception.
At the core node connection stage，the tax refund calculation base for manufacturing enterprises is by default based on the FOB (Free on Board) price marked on the customs declaration form. If the trade term is CIF (Cost Insurance and Freight) or CFR (Cost and Freight)，the corresponding international freight and insurance premium shall be deducted independently for separate accounting. For trade-oriented enterprises，the tax calculation base directly matches the tax-exclusive amount marked on the special input VAT invoice，and the tax refund amount is calculated according to the corresponding tax refund rate of the commodity.
In the abnormal contingency stage，if the pre-declaration is suspended or the tax authority indicates that the basis is questionable，export the doubt list from the pre-declaration feedback immediately，supplement the corresponding supporting materials and submit the explanation. Do not repeatedly submit invalid declarations which will cause the system to trigger a risk control alert. The new national tax refund coordination system launched in 2026 supports automatic cross-verification of documents for cross-customs area business. For cross-customs area export business，no additional off-site filing materials are required，and the review process can proceed normally as long as the four flows are consistent.
For the final compliance implementation requirement，all documents corresponding to the tax refund shall be retained and filed for 5 years，with both electronic and paper versions stored simultaneously to meet the verification requirements of subsequent tax documentary investigations. For declarations that fully meet the basis requirements，the conventional tax refund arrival cycle can be shortened to within 3 working days.

As one of the core bases for tax refund, the accuracy of the trade term, cargo value, and commodity code marked on the customs declaration form directly determines the subsequent tax refund review pass rate. If there is a deviation in the commodity code classification on the customs declaration form, even if all subsequent documents are consistent, the tax authority will directly reject the tax refund application. In 2026, data between the national integrated customs clearance system and the tax refund system has achieved real-time synchronization. The customs declaration data will be automatically synchronized to the tax end the day after the customs declaration is released, and enterprises do not need to upload the customs declaration copy manually.
If any error is found in the customs declaration data, the application for deletion and re-declaration shall be submitted within 30 days after the goods are released. Application for modification submitted after the time limit will be marked as abnormal operation by the customs system, which will synchronously affect the review credit rating at the tax refund end. In case of price verification disputes, prepare corresponding purchase contracts, foreign exchange payment certificates, and export customs declaration records of similar goods in the past 3 months in advance as supporting materials, to avoid obvious deviation between the goods value adjusted after customs price verification and the goods value declared by the enterprise for subsequent tax refund, which will cause unnecessary documentary investigation.

As the core cargo right certificate serving as the auxiliary basis for tax refund, the consignee name and consignee information on the bill of lading shall be logically consistent with the corresponding fields of the export contract and customs declaration form. For businesses settled under letter of credit, the full trace of endorsement transfer of the bill of lading shall be retained as supplementary supporting materials for subsequent tax refund verification.
In 2026, the free storage period of cross-border transportation routes including China-Europe Railway Express and Southeast Asia land transport is generally extended to 14 days. Enterprises can reasonably arrange the time nodes of container loading, customs declaration and shipment during delivery, to avoid shipment delay caused by overbooking and container roll, which will affect the departure time of exported goods and miss the tax refund declaration window of the current month.
In case of special situations such as port change or return of goods, obtain the official port change/return certificate issued by the shipping company or transportation platform immediately, and send it to the finance and tax personnel to adjust the tax refund declaration data. Do not force the submission of tax refund declaration with incorrect departure information, which will be identified as false declaration in subsequent verification.

During the calculation of the export tax refund basis, the VAT deferral policy promoted nationwide in 2026 can be reasonably applied to further optimize capital occupation efficiency. For manufacturing enterprises that import materials under the VAT deferral mode, the corresponding tax refund calculation basis of exported finished products can be calculated normally based on the FOB price, and there is no need to additionally deduct the deferred import VAT amount from the input VAT.
If the export business involves cross-border related transactions, prepare the independent third-party cargo value assessment report in advance to ensure that the export pricing is within the reasonable range of the industry, so as to avoid being judged as transfer pricing by the tax authority and having the tax refund calculation basis adjusted. All transaction details with overseas related parties shall be filed separately to meet the BEPS related verification requirements, so as to avoid triggering anti-tax avoidance investigation and affecting the normal tax refund progress.

As one of the core bases for export tax refund, the remitter name and remittance amount on the corresponding SWIFT or CIPS message of the foreign exchange collection certificate shall be completely consistent with the overseas purchaser on the export contract and the total cargo value marked on the customs declaration form. In 2026, data between the State Administration of Foreign Exchange and the State Taxation Administration has achieved real-time coordination.
The foreign exchange collection data will be automatically synchronized to the tax refund system, and enterprises do not need to upload the foreign exchange collection slip manually. However, in case of third-party payment, prepare the payment on behalf agreement and the statement of payment relationship in advance and submit them to the tax authority for filing, so as to avoid the system automatically marking the foreign exchange collection as abnormal and intercepting the tax refund application.
During the foreign exchange settlement operation, enterprises can complete the purchase and settlement of foreign exchange at the appropriate time of exchange rate fluctuation, and reasonably optimize the exchange difference income on the premise of not deviating from the real transaction cargo value. Do not falsely increase or reduce the customs declaration cargo value to arbitrage exchange difference, which will lead to excessive deviation between the tax refund calculation basis and the actual foreign exchange collection amount.

As the basic supporting document of the tax refund basis, the export contract shall clearly mark the core elements such as product name, specification, trade term, payment cycle, and rights and responsibilities of both parties. No clause shall conflict with the information of the customs declaration form and invoice. If a long-term framework export agreement is signed, add the order for each individual batch of shipment as an attachment, which shall be bound and filed one by one with the corresponding customs declaration form and invoice.
In case of special situations such as delayed delivery or goods return caused by force majeure, sign a supplementary agreement in time to clarify the division of responsibilities, and the corresponding clauses can be used as exemption supporting materials for subsequent tax refund abnormality verification. If the exported goods involve intellectual property rights, complete the customs protection filing for intellectual property rights in advance and obtain the corresponding authorization documents, to avoid the goods being seized during customs clearance, which cannot leave the territory normally and affect the validity of the tax refund declaration.

If the exported goods are subject to on-site customs inspection, the normal release notice and inspection record after the inspection is completed shall also be included in the tax refund document filing materials, as supplementary basis for the goods to leave the territory truly. During the inspection, cooperate with customs officers to provide the corresponding product name description and component list of the goods, to ensure that the goods information after machine detection and container unpacking inspection is completely consistent with the declared information on the customs declaration form.
Do not have the situation that the declared product name does not match the actual goods, which will cause abnormal inspection records that are subsequently synchronized to the tax refund system and directly trigger documentary investigation. If the goods need to be sent for laboratory test, obtain the official test report within the specified time limit, confirm that the classification result is consistent with the previously declared commodity code. If the customs declaration information is adjusted subsequently, update the corresponding data of the tax refund declaration in time to ensure the logical closed loop of all bases.

For exported dangerous goods or goods containing chemical components, the corresponding MSDS report and UN dangerous goods packaging appraisal certificate shall be filed together with the customs declaration form, invoice and contract, as auxiliary supporting basis for tax refund declaration. For customized packaging of ordinary goods, the corresponding packaging material purchase voucher and packaging design description can also be retained synchronously. When the tax documentary investigation questions the rationality of the cargo value in the future, these materials can be used as supplementary supporting documents for the composition of the cargo value.
The mark content on the goods packaging shall be consistent with the mark information marked on the customs declaration form. The higher the matching degree of the mark information during on-site inspection, the faster the customs clearance speed, which can further prove the authenticity of the business and reduce the probability of manual verification in tax refund review. After the new export packaging specification comes into effect in 2026, goods involving wooden packaging shall be affixed with the standard IPPC mark, and the corresponding fumigation certificate shall also be retained and filed synchronously.

Consistency of four flows is the core standard for verification of export tax refund basis in 2026. All corresponding vouchers of goods flow, capital flow, invoice flow and contract flow shall correspond to each other. Any loophole in any link will trigger tax documentary investigation and directly suspend the tax refund process. For tax refund businesses that are declared across months, export the pre-declaration verification report in advance, check the matching degree of all data, and do not skip the pre-declaration and submit the formal declaration directly.
If a tax documentary investigation is initiated, submit the scanned copies of all original filed documents within the specified 15 working days, take the initiative to cooperate with the verification personnel to sort out the full process details of the business, and do not delay the submission of materials which will cause the tax refund review cycle to be extended indefinitely. If minor capital return doubt is found during the verification, take the initiative to submit the corresponding statement of current account and subsequent transaction vouchers to quickly eliminate the doubt and resume the tax refund process as soon as possible.

The calculation of export tax refund basis can be optimized in coordination with supply chain architecture design. Enterprises can reasonably choose FOB or CIF trade terms, adjust the cargo value composition of the customs declaration form, and adapt to the tax refund calculation rules for different types of enterprises.
Manufacturing enterprises can arrange shared pre-positioned warehouses at surrounding ports, separate the domestic transportation link and export customs declaration link, further optimize the calculation base of FOB price, and avoid unnecessary extra costs included in the tax calculation basis. Through the full-link cost accurate calculation model, the expected tax refund revenue can be connected with the cost estimation of international logistics, procurement and production links, to predict the corresponding tax refund amount of different shipment batches in advance, reasonably arrange the overall capital turnover rhythm, avoid the overdue payment to upstream suppliers caused by delayed tax refund arrival, and improve the overall operation efficiency of the supply chain.
