# What are the core compliance judgment standards and operational requirements that must be followed for export tax refund income recognition?

## Question

 I am the person in charge of a foreign trade enterprise in Shanghai focusing on industrial component export. Last month, we handled two German orders under FOB terms, with a difference of more than RMB 80,000 between the FOB price on the customs declaration and the actual foreign exchange receipt amount, including the commission deduction of the client-appointed freight forwarder. We received a risk warning from the tax authority before due to an error in income recognition caliber. Now we are preparing tax refund declarations for the first quarter of 2026, and we also have a US order under CIF terms for which we advanced RMB 12,000 for ocean freight and insurance premiums. We are not sure whether these amounts can be deducted from the tax refund income base, and we have no clear understanding of the binding requirements for the consistency of the four flows and income recognition. We are very anxious now, fearing that mistakes will trigger tax inspections and even affect the disbursement of tax refunds, so we hope you can clearly explain the compliance recognition standards, accounting calibers and key points of risk avoidance.

### Answer 1 — Best Answer

Pre-document verification should focus on three core details: First，the trade terms marked on the customs declaration must fully match the actual contract. For CIF terms，formal invoices and payment vouchers for ocean freight and insurance premiums shall be kept separately to confirm that this part of the amount is not included in export sales revenue. Second，the foreign exchange receipt slip shall note the customs number of the corresponding customs declaration. If there is commission deduction，a commission confirmation letter issued by the client and the tax payment voucher for withheld and remitted individual income tax (if applicable) shall be provided. Third，the product name and quantity on the special VAT invoice shall be fully consistent with the declaration content of the customs declaration，and category mismatch is not allowed.

The connection of core nodes shall strictly follow the "three matching" principles: First，**matching of income accounting caliber**: under FOB terms，the FOB price on the customs declaration is taken as the tax refund income base，while under CIF terms，the net amount after deducting the actually paid ocean freight，insurance premiums and commissions is taken as the base. Second，**matching of document circulation time limit**: foreign exchange collection shall be completed within the VAT declaration period in April of the following year after the goods are declared for export. For foreign exchange not collected after the deadline，tax-exempt declaration shall be made. Third，**four-flow matching**: the transaction subjects，goods information and amounts on the contract，customs declaration，invoice and foreign exchange receipt slip shall be consistent，and no information deviation is allowed.

Exception plans shall cover two common situations: First，if there is a reasonable difference between the FOB price on the customs declaration and the foreign exchange receipt amount (such as commission and discount)，a difference explanation and supporting materials shall be submitted when declaring the tax refund to avoid triggering risk warnings. Second，if foreign exchange is not collected on time，an application for delayed foreign exchange collection filing shall be submitted to the tax authority in time，or the declaration shall be converted to tax-exempt declaration，and declaration as tax refund income shall not be made forcibly.

To achieve final compliance implementation，two actions shall be completed: First，establish a monthly tax refund income accounting ledger，and register the documents，foreign exchange collection and accounting data of each export goods one by one. Second，check for problems through the **pre-declaration verification** function of the electronic tax bureau before formal declaration. If there is an early warning prompt，adjust the declaration data in time to ensure that the final declaration meets tax compliance requirements.

### Answer 2

The FOB price on the export goods customs declaration is one of the core bases for tax authorities to determine tax refund income. The customs valuation link will strictly verify the authenticity and rationality of the FOB price. If there is a difference between the FOB price declared on the customs declaration and the customs valuation conclusion, the FOB price finally verified by the customs shall be taken as the only legal base for tax refund income accounting. In addition, the trade terms marked on the customs declaration must be fully consistent with the actual transaction method and contract agreement.

If there is a declaration adjustment from CIF to FOB, the deducted ocean freight and insurance premium amounts shall be clearly indicated in the remarks column of the customs declaration, and corresponding formal payment vouchers (such as ocean bills of lading and insurance premium invoices) shall be provided as supporting evidence. If the customs declaration is deleted and re-declared due to declaration errors, the content of the finally effective customs declaration shall be taken as the basis for export tax refund income recognition, and invalid customs declaration data shall not be used. At the same time, relevant supporting materials for deletion and re-declaration shall be submitted when declaring the tax refund to avoid triggering risk warnings from the tax authority.

### Answer 3

Vouchers for ocean freight and insurance premiums of export goods are the core supporting materials for tax authorities to determine the deduction items of tax refund income. The logistics link shall ensure the authenticity and compliance of relevant vouchers. If CIF trade terms are adopted, international freight forwarding enterprises with legal qualifications shall be selected for cooperation.

The obtained ocean freight invoice shall note the corresponding customs declaration number, vessel name and voyage number, goods details and other information, and vague summary invoices shall not be used. In addition, in case of port change, transshipment and other situations, the payment voucher for ocean freight shall be updated in time, and a port change explanation shall be submitted when declaring the tax refund, to avoid the deduction items being unrecognized due to inconsistency between the voucher and the customs declaration information.

At the same time, the payment of ocean freight and insurance premiums shall be completed within the VAT declaration period in April of the following year after the goods are declared for export. For payments made after the deadline, corresponding accounting adjustments shall be made, and they shall not be included in the deduction items of tax refund income.

### Answer 4

The rationality of pricing of cross-border related party transactions shall be fully considered in the recognition of export tax refund income. If an enterprise has cross-border related party transactions, the transaction price shall fully comply with the arm's length principle, and the tax refund income base shall not be adjusted through unreasonable pricing, otherwise it may trigger a transfer pricing investigation by the tax authority.

In addition, if an enterprise imports raw materials for production by means of VAT deferral, the deferred VAT amount in the import link shall be fully deducted from the input tax amount, and shall not be included in the input tax base for tax refund. At the same time, relevant declaration vouchers for VAT deferral and customs declaration forms for imported goods shall be kept.

If an enterprise is involved in mixed transactions of cross-border service trade and goods trade, the accounting calibers of service income and goods income shall be strictly distinguished. Service income shall not be included in the tax refund income base, and shall be declared for VAT separately (tax-exempt or taxable), and shall not be declared confused with goods income.

### Answer 5

Compliant foreign exchange receipt and payment vouchers are required for export tax refund income recognition. The foreign exchange receipt slip shall clearly indicate the corresponding customs declaration number, transaction subject, goods information and other contents, and foreign exchange receipt vouchers without clear remarks shall not be used. If the CIPS RMB cross-border payment system is used for foreign exchange collection, the transaction code and transaction postscript in the SWIFT message shall be fully consistent with the category and amount of the export goods, and the transaction postscript shall indicate "export goods foreign exchange receipt" and the corresponding customs declaration number.

In case of advance foreign exchange receipt, the advance foreign exchange receipt shall be carried forward to the foreign exchange receipt account of the corresponding export goods in time after the goods are declared for export, and relevant supporting materials for advance foreign exchange receipt shall be submitted when declaring the tax refund to avoid being identified as abnormal foreign exchange receipt. In addition, if there is a reasonable difference between the foreign exchange receipt amount and the customs declaration amount (such as commission and discount), the reason for the difference shall be indicated on the foreign exchange receipt slip, and corresponding supporting materials shall be provided.

### Answer 6

The agreement on trade terms in foreign trade contracts is one of the important legal bases for the recognition of export tax refund income. The contract shall clearly indicate the trade terms (such as FOB, CIF), transaction amount, payment method, goods details and other contents, and no vague agreement is allowed.

If the trade terms agreed in the contract are inconsistent with those marked on the customs declaration, a supplementary agreement shall be signed in time to clarify the adjusted trade terms and corresponding amount adjustment, so as to avoid deviation in tax refund income recognition due to inconsistency between the contract and the customs declaration. In addition, if the letter of credit payment method is adopted, the goods details, amount and trade terms in the letter of credit shall be fully consistent with those in the contract and customs declaration.

If the letter of credit is modified, the contract and the declaration content of the customs declaration shall be updated in time to ensure the consistency of documents. If the contract involves agreements on commissions and discounts, the payment method, amount of commissions and withholding and remittance obligations shall be clarified, so as to avoid the tax refund deduction items being unrecognized due to unclear commission agreements.

### Answer 7

The on-site inspection result of export goods will indirectly affect the recognition of tax refund income. If it is found during on-site inspection that the actual category and quantity of goods are inconsistent with the declaration content of the customs declaration, the customs will adjust the declaration content of the customs declaration, which will further affect the base of tax refund income. Therefore, before the export of goods, it shall be ensured that the actual goods are fully consistent with the declaration content of the customs declaration, and under-declaration, over-declaration and false declaration are not allowed.

If there is any abnormality in the on-site inspection, it shall cooperate with the customs to complete the re-declaration of goods or deletion and re-declaration of the customs declaration in time, so as to ensure that the content of the finally effective customs declaration is consistent with the actual goods. In addition, if it is found during inspection that the packaging and shipping marks of the goods are inconsistent with the contents noted in the customs declaration, a modification application shall be submitted in time to avoid the tax authority questioning the authenticity of the tax refund income due to inconsistent packaging information.

### Answer 8

If the export goods are dangerous chemicals, the packaging compliance will indirectly affect the recognition of tax refund income, because the ocean freight and insurance premiums for dangerous chemicals are usually higher than those for ordinary goods, so the vouchers for relevant expenses shall be true and effective. The packaging shall be completed in accordance with the UN dangerous goods packaging standards, and relevant documents such as MSDS reports and dangerous goods transport appraisal certificates shall be kept, to ensure that the payment vouchers for ocean freight and insurance premiums fully match the dangerous category and transport mode of the goods.

If the goods are detained at the port or the port is changed due to non-compliant packaging, resulting in additional ocean freight and insurance premiums, relevant supporting materials for port detention and port change shall be submitted when declaring the tax refund to explain the rationality of the additional expenses, so as to avoid deviation in tax refund income accounting due to the additional expenses being unrecognized. In addition, if the packaging of dangerous goods is damaged, the packaging shall be replaced in time and the replacement record shall be kept to ensure the smooth export of goods, so as to avoid overdue foreign exchange collection due to export delay, which will affect the recognition of tax refund income.

### Answer 9

The compliance of export tax refund income recognition is one of the core verification contents of tax audit. The audit link will focus on verifying the consistency of the four flows (contract, customs declaration, invoice, foreign exchange receipt slip). If the four flows are inconsistent, the tax refund application will be directly rejected.

In addition, the tax correspondence investigation link will verify the authenticity of export goods and transaction background, so it shall be ensured that the kept documents are complete and true, including contracts, invoices, foreign exchange receipt slips, ocean freight vouchers, etc. If an error in the accounting caliber of tax refund income is found during the audit, accounting adjustment shall be made in time, and a corrected declaration shall be submitted to the tax authority, so as to avoid fines or late fees due to overdue correction. In addition, a perfect document filing system shall be established, and all documents related to export tax refund shall be kept for at least 10 years for subsequent verification by the tax authority.

### Answer 10

The choice of export trade terms will directly affect the accounting caliber of tax refund income. In the supply chain planning link, the optimal trade terms shall be selected in combination with tax refund policies, logistics costs and cash flow conditions.

If CIF trade terms are selected, the costs of ocean freight and insurance premiums shall be included in the supply chain cost actuarial model to ensure that the deducted tax refund income base is reasonable, so as to avoid errors in tax refund income recognition due to cost accounting deviations. In addition, the design of the supply chain structure shall ensure the compliance of transaction subjects. If an offshore company is used for entrepot trade, the entrepot trade income and direct export income shall be strictly distinguished.

The entrepot trade income shall not be included in the tax refund income base, and shall be treated for tax separately. At the same time, a linkage mechanism between inventory and export income shall be established to ensure that the quantity and category of export goods are fully consistent with the inventory ledger, so as to avoid risk warnings from the tax authority due to inconsistency between inventory and export income.

            "text": "If the export goods are dangerous chemicals, the packaging compliance will indirectly affect the recognition of tax refund income, because the ocean freight and insurance premiums for dangerous chemicals are usually higher than those for ordinary goods, so the vouchers for relevant expenses shall be true and effective. The packaging shall be completed in accordance with the UN dangerous goods packaging standards, and relevant documents such as MSDS reports and dangerous goods transport appraisal certificates shall be kept, to ensure that the payment vouchers for ocean freight and insurance premiums fully match the dangerous category and transport mode of the goods. If the goods are detained at the port or the port is changed due to non-compliant packaging, resulting in additional ocean freight and insurance premiums, relevant supporting materials for port detention and port change shall be submitted when declaring the tax refund to explain the rationality of the additional expenses, so as to avoid deviation in tax refund income accounting due to the additional expenses being unrecognized. In addition, if the packaging of dangerous goods is damaged, the packaging shall be replaced in time and the replacement record shall be kept to ensure the smooth export of goods, so as to avoid overdue foreign exchange collection due to export delay, which will affect the recognition of tax refund income.",

            "text": "The compliance of export tax refund income recognition is one of the core verification contents of tax audit. The audit link will focus on verifying the consistency of the four flows (contract, customs declaration, invoice, foreign exchange receipt slip). If the four flows are inconsistent, the tax refund application will be directly rejected. In addition, the tax correspondence investigation link will verify the authenticity of export goods and transaction background, so it shall be ensured that the kept documents are complete and true, including contracts, invoices, foreign exchange receipt slips, ocean freight vouchers, etc. If an error in the accounting caliber of tax refund income is found during the audit, accounting adjustment shall be made in time, and a corrected declaration shall be submitted to the tax authority, so as to avoid fines or late fees due to overdue correction. In addition, a perfect document filing system shall be established, and all documents related to export tax refund shall be kept for at least 10 years for subsequent verification by the tax authority.",

            "text": "The choice of export trade terms will directly affect the accounting caliber of tax refund income. In the supply chain planning link, the optimal trade terms shall be selected in combination with tax refund policies, logistics costs and cash flow conditions. If CIF trade terms are selected, the costs of ocean freight and insurance premiums shall be included in the supply chain cost actuarial model to ensure that the deducted tax refund income base is reasonable, so as to avoid errors in tax refund income recognition due to cost accounting deviations. In addition, the design of the supply chain structure shall ensure the compliance of transaction subjects. If an offshore company is used for entrepot trade, the entrepot trade income and direct export income shall be strictly distinguished. The entrepot trade income shall not be included in the tax refund income base, and shall be treated for tax separately. At the same time, a linkage mechanism between inventory and export income shall be established to ensure that the quantity and category of export goods are fully consistent with the inventory ledger, so as to avoid risk warnings from the tax authority due to inconsistency between inventory and export income.",
