I am the foreign trade manager of a small and medium-sized foreign trade enterprise based in Shanghai, mainly exporting Nordic household goods. I have been entrusting an agency to handle tax refund declaration for 3 years of doing foreign trade. This year, to cut costs, we hired a full-time finance staff. Last month, we conducted the first independent declaration of export tax refund for the first quarter of 2026, but we got stuck at the pre-declaration stage.

The system prompted "inconsistency between electronic customs declaration information and value-added tax invoice information". We have spent nearly two weeks checking with the customs broker and the invoice issuer, but have not found the problem. Now the foreign exchange collection for this shipment has been credited, and there are only 8 days left before the declaration deadline.

I stay up late checking materials every day and am extremely anxious. I would like to ask about the complete process steps of export tax refund declaration, the emergency treatment methods for pre-declaration errors, and how to avoid such comparison abnormalities from the source. It would be great to get some practical details, such as how to review documents?

Among them，the first 4 digits of the commodity code on the customs declaration must be consistent with that on the value-added tax invoice，and the difference between the foreign exchange collection amount and the FOB price on the customs declaration shall not exceed 5%. If it exceeds，the shall be submitted. Meanwhile，you need to log in to China E-Port to check the status of the tax refund copy of the customs declaration，and confirm it has been issued and synchronized to the tax system (usually synchronized 3-5 working days after customs release，7-10 working days after inspection and modification).

Electronic customs declaration information is the core basis for export tax refund declaration. In 2026, the information synchronization lead time between the General Administration of Customs and the State Taxation Administration has been compressed to 3-5 working days after customs declaration release. However, if special circumstances such as on-site inspection and commodity code modification are involved, the synchronization lead time may be extended to 7-10 working days. If pre-declaration prompts "missing customs declaration information", you first need to log in to the "Export Tax Refund Online Inspection System" of China E-Port to check the "tax refund copy status" of the customs declaration. If it shows "issued", it means the customs has pushed the information, and you need to contact the export tax refund division of the competent tax authority to apply for manual synchronization of customs declaration information in the tax system; if it shows "not issued", you need to submit the to the customs broker, attach materials such as the original customs declaration and release notice, and request the customs to re-issue the tax refund copy and push the information. In addition, note that the first 4 digits of the commodity code on the customs declaration must be consistent with that on the value-added tax special invoice, otherwise a comparison abnormality will be triggered.

In 2026, the export tax refund policy has further optimized the connection mechanism between VAT residual credit refund and export tax refund. If a foreign trade enterprise has both VAT residual credit and export tax refund payable, it can independently choose to prioritize export tax refund declaration or jointly declare residual credit refund and export tax refund. If you choose to prioritize export tax refund declaration, you need to submit the in the "Export Tax Refund Declaration Module" of the electronic tax bureau, and the tax authority will complete the review and refund the export tax within 3 working days; if you choose joint declaration, you need to calculate the residual credit and export tax refund payable together, and the refund amount is the smaller of the two. In addition, 2026 has removed the selection restriction of "tax first refund later" and "exemption and refund" for foreign trade enterprise export tax refund, enterprises can flexibly choose the declaration method according to their own situation, but note that once selected, it cannot be changed within the year.

The core of 2026 export tax refund compliance verification is consistency of four flows (cargo flow, capital flow, invoice flow, contract flow), among which capital flow verification is the key monitoring target of tax authorities. If an enterprise has capital backflow (i.e. transferring part of the capital back to overseas suppliers or related parties after foreign exchange collection), it will be deemed non-compliant, trigger tax correspondence inspection, and even suspend the export tax refund qualification. To avoid such risks, enterprises need to ensure that the foreign exchange collection account is the enterprise's public settlement account, the difference between the foreign exchange collection amount and the FOB price on the customs declaration shall not exceed 5% (a shall be submitted for special cases), and the source of the collected foreign exchange must be consistent with the buyer in the export contract. In addition, Shanghai region requires electronic filing of export tax refund documents in 2026, documents such as contract, customs declaration, VAT invoice, foreign exchange collection receipt need to be scanned and uploaded to the "document filing module" of the electronic tax bureau, and kept for 5 years.

The compliance of export tax refund declaration is closely related to the terms of international trade contracts. In 2026, tax authorities will focus on checking the information consistency among contract, customs declaration and VAT invoice during verification.

If information such as product name, specification, quantity, price, trade term in the contract is inconsistent with that in the customs declaration or VAT invoice, it will be deemed non-compliant and trigger tax correspondence inspection. To avoid such risks, enterprises need to clearly agree that all information shall be consistent with the customs declaration and VAT invoice when signing the contract.

If contract terms need to be modified due to market changes, you need to notify the customs broker and finance department in time to synchronize the modification of information on the customs declaration and VAT invoice. In addition, if export or foreign exchange collection cannot be completed on time due to force majeure, enterprises need to keep relevant supporting materials (such as buyer's deferred payment letter, force majeure certificate, customs port congestion certificate, etc.) to apply for extension of export tax refund declaration to the tax authority.

On-site customs inspection of export goods may affect the synchronization of electronic customs declaration information and export tax refund declaration. If after the goods are inspected, the customs modifies core information such as commodity code, quantity and price on the customs declaration, the customs broker needs to push the modified customs declaration information to the General Administration of Customs E-Port within 2 working days, then E-Port synchronizes it to the tax system, this process usually takes 3-5 working days. If an enterprise finds that the customs declaration information is inconsistent with the actual situation during pre-declaration, it needs to contact the customs broker in time to check whether there is any modification after inspection, if yes, you need to wait until the modified information is synchronized to the tax system before conducting pre-declaration. In addition, if the goods are deemed non-compliant after inspection (such as incorrect commodity classification), the enterprise needs to modify the customs declaration in time and submit the to the tax authority, otherwise it cannot pass the pre-declaration comparison review.
