What Core Documents and Supporting Materials Must Be Prepared for 2026 Export Tax Refund Applications?

Question

I am the head of a small and medium-sized foreign trade enterprise specializing in customized furniture in Shanghai. I just shipped a batch of cabinets to Hamburg, Germany last month. This is my third self-operated export order this year. Previously, I relied entirely on agents to handle tax refund, and this time I want to go through the process on my own to cut costs.

However, after checking the latest 2026 tax refund policies last night, I found that the document requirements are much stricter than last year. I stayed up until 1 a.m. but still couldn't sort it out clearly. Just now when I checked the documents, I also found a slight discrepancy between the product name on the customs declaration and that on the VAT special invoice, which makes me very nervous.

I am worried that missing key materials will cause the tax refund audit to get stuck, or even trigger tax risk control. I would like to ask what materials are exactly needed for an export tax refund application? Are there any special requirements or room for simplification especially for small and medium-sized foreign trade enterprises?

First，complete Pre-Audit of Document Consistency : In 2026，tax authorities have upgraded the requirements for tax refund document matching. You need to check in advance the product name，specification，quantity and FOB price on the tax refund copy of the customs declaration，against the corresponding fields of the VAT special invoice (for foreign trade enterprises)，self-produced goods certificate (for manufacturing enterprises)，and export sales invoice. The error shall not exceed 1%，to avoid triggering risk control warning due to mismatching. Organize Core Document Checklist : For both foreign trade and manufacturing enterprises，the core materials are: Customs Declaration for Export Goods (Special Tax Refund Copy)，VAT Special Invoice Deduction Copy (for foreign trade enterprises)/VAT Tax Return (for manufacturing enterprises)，Export Sales Invoice，and Bank Receipt for Foreign Exchange Collection (2026 requires collection within 180 days after export，application for extension shall be submitted in advance for special circumstances)，auxiliary materials include bill of lading，packing list，and purchase-sales contract (only electronic archiving is required). Prepare Response Plan for Discrepancies and Abnormalities in advance: If there is a slight discrepancy between the product name on the customs declaration and the invoice (like the situation you encountered)，you need to issue a with your company seal，attach supporting materials such as the customization modification confirmation from the customer and production process sheet，and upload it to the "Abnormal Tax Refund Declaration Module" of the electronic tax bureau at the same time，to avoid audit hold-up. Utilize Simplification Policy for Small and Medium-sized Enterprises : In 2026，for small and medium-sized foreign trade enterprises with annual export volume below USD 5 million in Shanghai，you can apply for simplified document filing. It is not required to keep paper packing lists and bills of lading，you only need to archive electronic copies in the "Tax Refund Document Management System" of the international trade single window，which saves sorting costs.

In 2026, customs have upgraded the requirements for issuing tax refund copies of export customs declarations. You must clearly check the "For Tax Refund" mark when declaring, and the country of arrival, final destination country, product name, and HS code must fully match the foreign trade contract. If there is an error in HS code classification, you must apply for amendment within 10 working days after the customs declaration is issued, otherwise the tax refund copy will be marked as "non-compliant" and cannot be used for tax refund applications.

In addition, the electronic data of the customs declaration must be synchronized to the electronic tax bureau within 3 working days after export. If the data is not synchronized due to system delay, you need to contact the "Tax Refund Data Synchronization Window" at the customs declaration hall to trigger manual data push, to avoid delaying tax refund due to missing data.
