I am the manager of a small foreign trade enterprise specializing in outdoor hardware accessories, and I have only been in the industry for half a year. Our first export tax refund declaration was rejected by the system immediately last week, and the tax authority informed us that several documents were missing and did not meet the requirements. Now the declaration period is only one week away from the deadline.
I heard from peers a few days ago that failing to supplement missing documents in time will at least delay the tax refund arrival by two to three months, and at worst trigger cross-region verification inquiries, locking all subsequent tax refund businesses for inspection in the next six months. I have no clear understanding of the compliance requirements now, and I just want to figure out what documents need to be prepared for export tax refund under different business scenarios to avoid further pitfalls that affect normal operations.

Basic declaration electronic documents can be exported and organized in advance from the Single Window，including the official electronic information of the 2026 version customs declaration form and the electronic information of the deduction copy of the special VAT invoice for input tax. There is no need to submit paper copies offline. Import them into the tax refund declaration system to complete pre-declaration verification and proactively identify issues of information inconsistency.
Core archived paper documents include copies of export goods detailed list，shipping order，and full journey transportation documents affixed with the company's official seal. The commodity name，quantity，and weight information on all documents must fully match those on the customs declaration form，with no logical conflicts allowed. Submit the official declaration only after passing the pre-declaration verification to avoid triggering the manual review channel.
Supplementary documents for different special business scenarios can be organized as needed. For cross-border e-commerce B2B businesses，prepare additional overseas warehouse delivery vouchers and screenshots of online transaction orders. For cross-customs-district declaration businesses，just supplement with screenshots of the customs declaration draft from the corresponding port. If the pre-declaration prompts information asymmetry，contact the customs broker immediately to synchronize and correct the customs-side data，do not forcefully submit the declaration. All paper documents must be retained for inspection for 5 years，and no arbitrary alterations are allowed.
Follow up on the review status within 3 working days after submitting the official declaration. Complete the supporting documents immediately upon receiving the inspection notice. Currently，the average review cycle for eligible enterprises has been shortened to 3 working days，and the tax refund can be credited quickly if all documents are complete and correct.

If the domestic source of goods on the customs declaration form is incorrectly filled in, it will be directly blocked by the tax refund review system even if all other documents are complete. In 2026, the source of goods field in the national customs clearance integration system has been automatically linked and compared with the registration address of the supplier enterprise on the input tax invoice.
In case of a mismatch, an application for modifying the customs declaration form must be submitted immediately. Submit a situation explanation, copy of the input tax invoice, and delivery voucher of the supplier enterprise to the original declaration port.
After the field correction is completed within 3 working days, the customs-side data will be automatically synchronized to the tax refund system, which will not affect the subsequent declaration progress. Do not directly modify the customs declaration information in the tax refund system by force, as it will directly trigger a data abnormality warning.

The verification requirement of "four flows consistency" (goods flow, capital flow, invoice flow, contract flow) has been included in the 2026 tax refund pre-verification rules. Before submitting the declaration, check all information of the goods flow, capital flow, invoice flow, and contract flow one by one. The names of the transacting parties, commodity name, and transaction amount in the contract must fully correspond to those in the other three types of documents.
If the foreign exchange collection time for an order exceeds 90 days after the export date on the customs declaration form, a foreign exchange collection situation explanation must be submitted in advance; do not wait until the system triggers an overdue warning to supplement the materials. After the verification inquiry is initiated, organize all supporting materials for the entire transaction chain immediately and proactively submit them to the competent tax authority. The inspection cycle can be shortened to a maximum of 15 working days.

Foreign exchange collection vouchers are a core component of tax refund documents. In 2026, the cross-border foreign exchange collection messages of the CIPS system have realized direct connection with the tax refund system, so there is no need to manually upload bank receipts additionally. As long as the transaction is true and verifiable, the foreign exchange collection data will be automatically synchronized to the declaration background.
If some orders are collected through offshore accounts, the corresponding foreign exchange collection receipts and domestic transfer vouchers must be organized in advance and filed for inspection together with the transaction background explanation. Do not allow the foreign exchange collection entity to be completely inconsistent with the name of the overseas purchaser, otherwise it will be judged as abnormal capital flow.

If the export goods corresponding to the tax refund have been inspected on-site by the customs, organize the inspection notice at that time, photos of the seals after inspection, and actual photos of the goods after unpacking in advance, and place them separately in the filing document folder.
Once the tax authority sends a letter requesting verification of the authenticity of the goods, submitting these materials directly can complete the verification quickly, without the need to repeatedly travel to the port to retrieve historical inspection records. Note that the shooting time of all photos must fully correspond to the time on the inspection form, and there should be no content that is taken later and inconsistent with the actual shipment status at that time.

If your enterprise meets the eligibility criteria for the 2026 export tax refund VAT deferral policy, there is no need to prepare additional deduction certificates for special VAT input invoices; you only need to submit the corresponding deferred tax declaration vouchers. Businesses applying the deferral policy do not need to authenticate and deduct input invoices in advance, which can significantly reduce the enterprise's capital occupation cost.
The access threshold only requires the enterprise to have a customs credit rating of general credit or above and no previous tax violation records to apply. File the documents for deferred business and ordinary business separately in advance to avoid confusion between the documents of the two types of businesses, which may affect subsequent accounting.

All export contracts signed with overseas purchasers must be affixed with valid signatures and seals of both parties; do not only retain electronic contracts without signatures and seals. If the order is confirmed via email correspondence, print out all screenshots of complete email correspondence and transaction details confirmed by both parties, sign them, and file them.
If the transaction involves letter of credit settlement, retain the original letter of credit, presentation documents, and bank acceptance notice as filing materials. In case of subsequent transaction disputes or tax inspections, these materials can serve as core evidence of transaction authenticity, avoiding the cancellation of tax refund eligibility due to incomplete documents.
