I run a small foreign trade enterprise specializing in the export of outdoor camping supplies. We have expanded our business to European, American and Southeast Asian markets only in the past two years. Previously, we always entrusted a bookkeeping agency to handle our tax refund affairs, but last week the agency notified us that due to full system upgrade, they will no longer serve small-volume clients like us.
I spent a long time fumbling with the entrance of the Electronic Tax Bureau on my own, only to encounter prompts that the export customs declaration information was not synchronized, or that the input VAT invoice information failed to match. After three days of trial and error, I did not even successfully submit the pre-declaration.
The monthly declaration period is due in one week, and overdue declaration will lead to tax exemption treatment or even deemed domestic sales and supplementary tax payment. I have worked overtime for two consecutive days to sort out documents in a rush, just trying to figure out how to complete export tax refund declaration step by step under the 2026 current rules, and find a practical operation guide that I can follow directly to avoid all kinds of common pitfalls.

First complete the pre-document verification step，sort out all four types of basic materials you have: the tax refund copy of export goods customs declaration form，the deduction copy of special VAT invoice，export purchase and sales contract，and original bill of lading，and check one by one whether the three core fields of product name，quantity and transaction amount are fully matched. The data synchronization timeliness of the newly launched 2026 International Trade Single Window has been shortened to 3 working days after customs declaration. You can first log in to the "Data Self-Inspection" page of the export tax refund declaration module in the Electronic Tax Bureau，to confirm that the information of customs declarations and input invoices have been automatically synchronized to the system without missing or mismatched fields.
Enter the core node connection step. After confirming that all data are correct，submit the pre-declaration first to complete the system automatic verification，check and correct all logic errors prompted by the system one by one，and initiate the formal declaration only after all errors are cleared. After the formal declaration is submitted，there is no need to submit paper materials offline，and the system will automatically transfer the application to the local tax refund authority and put it into the review queue.
Support the process with proper exception contingency plan. If correspondence audit is triggered during the review process，you should immediately file and submit all sorted "four flows matching" materials (contract，logistics manifest，foreign exchange receipt memo，input invoice)，and do not piece together materials at the last minute which will prolong the review cycle.
Complete the final compliant implementation. Under normal circumstances，within 3 working days after the review is approved，the tax refund will be directly transferred to the corporate public account reserved by your enterprise. After the declaration is completed，remember to keep all relevant documents for 10 years for future reference，to avoid the problem of missing materials in subsequent traceability.

The three core fields of export date, transaction term and HS code on the customs declaration are directly related to the matching degree of tax refund declaration. If there are wrong or missing fields in previously declared customs declarations, do not forcibly modify them in the tax refund system. First log in to the customs declaration modification application module of the International Trade Single Window, submit corresponding supporting materials to apply for modification. After the customs approves the application, the data will be automatically synchronized to the tax authority side, and no cross-system data difference will occur.
If the system prompts that the customs declaration information does not exist, first check whether the export date on the customs declaration exceeds the latest declaration deadline. In 2026, the latest deadline for tax refund declaration has been adjusted to the due date of the VAT declaration period in April of the year following export. For unsubmitted declarations that exceed the time limit, you can apply for extended filing later, and do not voluntarily transfer to domestic sales treatment which will cause extra tax burden losses.

The consignee information, shipment date and container number information on the bill of lading must be fully matched with the corresponding fields on the customs declaration. If the actual shipment date is later than the scheduled date due to container rolling over by the logistics carrier, you should update the shipment date on the bill of lading in time to keep it consistent with the export date on the customs declaration, to avoid logical time contradictions.
For export businesses under FOB terms, you should ask the freight forwarder for the scan copy of the official original bill of lading in advance, and obtain relevant logistics manifests within 7 days after the goods are shipped. Do not ask the freight forwarder for documents until the declaration period is approaching, since some freight forwarders only keep business documents for 18 months, and it will be very difficult to retrieve the original logistics vouchers after the retention period expires, which will directly hinder the subsequent progress of tax refund declaration.

If your enterprise meets the qualification of the new 2026 foreign trade enterprise VAT deferral policy, you can directly apply for deferred VAT payment at the import link, no need to prepay a large amount of VAT during import, which can greatly improve the cash flow turnover efficiency of the enterprise.
When applying for this qualification, the enterprise shall mark the corresponding field for deferred VAT separately in the input invoice column during subsequent tax refund declaration, the system will automatically match the corresponding deferred ledger, and no additional offline materials are required. Note that the fluctuation range of related party transaction pricing shall not exceed the plus or minus 10% interval stipulated by the local tax authority, to avoid triggering BEPS-related risk verification and affecting the normal review progress of tax refund declaration.

The difference between the amount of all foreign exchange receipt memos corresponding to exports and the transaction amount on the customs declaration shall be controlled within 5%. For the difference exceeding the floating range, you should prepare corresponding supporting materials for commission and deduction descriptions in advance, to prevent the system from judging the foreign exchange receipt as abnormal.
If you complete the foreign exchange receipt through the CIPS cross-border RMB payment channel, you should keep the corresponding RMB payment message, the transaction remark in the message must fully correspond to the category of the exported goods, no vague expressions are allowed, to prevent information mismatch problems in subsequent foreign exchange settlement, account reconciliation and tax refund declaration. For businesses that receive foreign exchange through offshore accounts, you should file the documents of corresponding transactions separately in advance, to quickly retrieve them for subsequent verification when needed.

All foreign trade contracts involved in tax refund declaration shall clearly mark core elements such as specifications, models, unit price of transaction subject, delivery time and payment nodes, no vague clause expressions are allowed.
If you sign a long-term framework agreement with overseas clients, supplementary orders for each single batch of export shall be kept separately, with the corresponding export customs declaration number clearly marked, to ensure that each tax refund declaration business has corresponding contract support. For export goods involving intellectual property rights, you shall complete IPR customs protection filing in advance, to avoid compliance disputes in subsequent inspection links that slow down the overall tax refund declaration progress.

If the HS code of the customs declaration is temporarily adjusted due to on-site customs inspection, you shall obtain the official inspection notice issued by the customs immediately, and update the corresponding HS code in the tax refund declaration system synchronously, to ensure that the declared information is completely consistent with the information on the final customs declaration. If subsequent inspection and appraisal of relevant goods attributes is required, you shall update the declaration data within 3 working days after obtaining the official test report.
Do not forcibly submit the declaration using the original wrong HS code, otherwise it will directly trigger a risk warning in the tax refund system, which will delay the review process by at least 2 to 3 weeks. All inspection-related documents shall be filed together with other tax refund documents for future reference.

Before submitting the tax refund declaration, you can make dynamic calculation on the declaration cost under different trade terms. The declared amount under CIF terms shall include freight and insurance premium, while the declared amount under FOB terms only calculates the actual transaction value of the goods.
Do not confuse the declaration calibers of the two terms, to avoid excessive deviation between the declared amount and the actual goods value. If the enterprise has both domestic sales and export businesses, you can formulate an inventory linkage strategy in advance, reasonably match the deduction and transfer-out proportion of input invoices, make full use of the tax refund policy dividend to reduce the overall comprehensive tax burden of the enterprise, and fill in the data according to the corresponding classified accounting rules during declaration.
