What Documents Are Required for 2026 Export Tax Refund? A Must-See Checklist for Enterprise Declaration

2026 Export Tax Refund Declaration: What Core Documents Do Enterprises Need to Provide?

In the first half of 2026,Shanghai Customs data shows that the number of export tax refund declarations by local foreign trade enterprises increased by 12% year-on-year,but nearly 18% of them experienced declaration delays due to incomplete documents,with an average delay of 7 days.Many foreign trade practitioners have reported that with policy updates,the requirements for "relevance" and "accuracy" of documents required for export tax refunds have become increasingly strict — this is also the core reason why many Shanghai foreign trade enterprises choose professional agencies.

1.Core Analysis of 2026 Export Tax Refund Policy: 3 Key Changes

Since the beginning of this year,the State Taxation Administration and the General Administration of Customs have targeted optimized the export tax refund policy,focusing on the two directions of "precision tax refund + compliance prevention and control".The key changes are concentrated in the following 3 points:

• Dynamic Matching of Tax Rebate Rates: Technical Parameters Must Be Provided Simultaneously for Partial Product Tax Rebate Rate Increases: For 12 categories of mechanical and electrical products including new energy vehicle parts and high-end medical devices,the tax rebate rate has been increased from 13% to 15%.However,enterprises are required to provide product technical parameter certificates (issued by a third-party testing institution or automatically matched through the Customs "Product Traceability System") to avoid the risk of "overreporting tax rebate rates".
• Full Coverage of Paperless Declaration: Electronic Documents Must Be Retained with Signatures: All production-oriented and foreign trade-oriented export enterprises are required to upload encrypted documents through the electronic tax bureau,and the submission of paper customs declarations and verification forms is cancelled.However,electronic signature versions (including customs declarations,contracts,bills of lading,etc.) must be retained within the enterprise for subsequent verification.
• Upgrade of Document Consistency Verification: New "Contract-Logistics-Funds" Relevance Requirements: The tax authorities have added verification items such as "the description of goods in the export contract must match the bill of lading" and "the foreign exchange payee must match the buyer in the contract".Enterprises are required to provide a matching list of booking notes,bill of lading copies,and foreign exchange payment slips.If there are discrepancies,a written explanation must be provided.

2.Impact of Policy Changes on Enterprises: Opportunities and Challenges Coexist

In response to the 2026 policy adjustments,Mr.Hua from a Shanghai foreign trade agency analyzed based on client service experience that enterprises need to respond from two dimensions: "opportunities" and "challenges":

Opportunities:

• The increase in tax rebate rates for some products directly increases corporate cash flow: For example,the company of Mr.Duan,a Shanghai electronic enterprise,saw its tax rebate rate for exported smart sensors rise from 13% to 15% this year,increasing monthly tax refunds by nearly 120,000 yuan;
• Paperless declaration saves offline submission time: Previously,enterprises needed to visit 3 departments to submit paper documents,but now declarations can be completed online in 1 day,shortening the cycle by 40%.

Challenges:

• Higher compliance requirements easily lead to omissions: Nearly 30% of enterprises have been rejected for failing to provide technical parameter certificates,and some enterprises have extended verification time due to unmarked discrepancies between contract goods descriptions and bill of lading;
• Increased difficulty in managing electronic documents: Enterprises need to establish an archiving system for electronic signature documents to avoid affecting subsequent tax refunds due to lost materials.

3.Zhongshen’s On-Site Services: Helping Enterprises Solve "Document Problems"

To address the pain points of enterprises in tax refund documents,Zhongshen has launched customized services of "tax refund document pre-review + compliance matching + electronic archiving" based on its 20+ years of industry experience.The specific practices include:

1.Document Pre-Review: Early Detection of Omissions:

For example,when a Shanghai medical device enterprise led by Ms.Ling declared tax refunds for high-end medical equipment for the first time this year,it was rejected by the tax authorities for failing to prepare technical parameter certificates issued by a third-party testing institution.Zhongshen’s specialist detected this issue during the pre-review,assisted the enterprise in contacting the testing institution to supplement the materials,and finally shortened the tax refund cycle from the original 15 days to 8 days.

2.Compliance Matching: Ensuring Document Consistency:

Zhongshen will sort out the "contract-logistics-funds" matching list for enterprises.For example,when a client of Mr.Hua’s foreign trade agency exported textiles,the contract goods description was "cotton T-shirt" and the bill of lading was marked "cotton T-shirt".The specialist will assist in adding the English goods description to the contract to avoid verification discrepancies.

3.Electronic Archiving: Standardizing Document Retention:

In response to the paperless declaration requirements,Zhongshen helps enterprises build an electronic archiving system,encrypt and store all tax refund documents,and mark the electronic signature date for easy retrieval during subsequent tax verification.

5.Practical Suggestions for Enterprises: Establish a "Tax Refund Document Checklist"

In response to the 2026 policy requirements,Zhongshen recommends that enterprises verify against the following checklist before each declaration:

• Have you prepared technical parameter certificates for products with adjusted tax rebate rates?
• Do all electronic documents carry the enterprise’s electronic signature?
• Are the goods descriptions in the export contract,bill of lading,and packing list consistent?
• Does the payer of the foreign exchange payment slip match the contract buyer?

If enterprises are unfamiliar with document preparation,they can contact professional agencies for pre-review in advance to avoid delays caused by incomplete documents.
