2026 Complete Operational Guide for Full Procedures of Foreign Trade Export Tax Refund

I.Core Procedure Framework for 2026 Export Tax Refund

After completing export,enterprises shall complete authentication within 30 days of the issuance of VAT invoices,and submit the following 5 types of core documents to the competent tax authority simultaneously:

• Export declaration form stamped with customs verification seal (special copy for export tax refund)
• Export foreign exchange verification and cancellation form (pilot enterprises in 2026 may replace it with bank slip)
• Special VAT invoice (shall be consistent with declaration elements on the customs declaration form)
• Export invoice (amount converted into RMB based on FOB price)
• Electronic Data for Formal Declaration of Export Goods Tax Refund (Exemption)

Key Reminder: For manufacturing enterprises,the declaration of tax exemption,credit and refund shall be completed first; for foreign trade enterprises,the corresponding input invoices shall be checked in the tax refund declaration system,and the system will automatically verify the matching degree between invoice and customs declaration data.

II.Coping Strategies for 2026 Export Tax Rebate Rate Adjustments

Since January 2026,the tax rebate rate for high energy-consuming products has been reduced by 2 percentage points,while the rebate rate for pilot products in comprehensive cross-border e-commerce pilot zones remains 13%.Take a photovoltaic module enterprise as an example (Scenario S: product HS code 94021010,tax rebate rate reduced from 17% to 15%):

Practical Suggestion: Enterprises shall communicate with Zhongshitong customs declaration team 3 months in advance to reclassify HS codes (for example,adjust 94021010 to 94021090,with tax rebate rate remaining 17%),and submit FORM A certificate of origin simultaneously (tariff reduction and exemption is applicable for RCEP member countries).

III.Certificate of Origin Endorsement and Tariff Reduction & Exemption

The RCEP agreement was upgraded in 2026,with new provisions for automatic determination of Regional Value Content (RVC).Take a chemical enterprise exporting to Indonesia as an example (task: apply for tariff reduction and exemption):

• Action 1: Apply for FORM R certificate of origin through Zhongshitong agency,with commercial invoice,packing list and product composition list required to be submitted
• Action 2: Verify RVC calculation logic 7 working days in advance (for chemical products: if the value proportion of imported materials is less than 60%,reduction and exemption is applicable)
• Action 3: File enterprise information in Indonesia customs system to avoid rejection due to "non-origin materials not listed separately"

Risk Warning: The certificate of origin shall be submitted 24 hours before the departure of goods.Overdue submission will be judged as "non-origin goods",which directly affects tariff reduction and exemption (for example,the EU imposes anti-dumping duties of 12%-45% on non-GSP products).

IV.2026 Customs Valuation and Inspection Risk Prevention

Customs will trigger inspection for "declared price significantly lower than similar goods in the same period" (for example,a hardware tool enterprise declares a unit price of RMB 5 per piece,while the average price in the customs database for the same period is RMB 8 per piece).Zhongshitong agency’s practical operation steps:

• Pre-valuation: Submit the Application Form for Price Pre-classification to customs in advance,with product manual and test report attached
• Declaration element verification: Ensure that "brand/model/material" is completely consistent with the VAT invoice (an instrument enterprise had its application returned due to missing "XX" in the "brand" column)
• Second declaration: If the first inspection fails,supplement the Price Explanation Letter within 24 hours,with third-party price evaluation report attached

Pitfall Avoidance Guide: Enterprises shall not deliberately underdeclare prices to "pay less tax".Customs will implement the "Price Traceability System" in 2026,with networked verification of data in the past 3 years.Once discovered,it will affect the credit rating,leading to export quota restriction in the next year.

V.Nodes and Time Limitation of Full Tax Refund Procedure

Through the coordination of "cross-region declaration at national ports + global agency network",Zhongshitong shortens the tax refund cycle to:

• Document pre-review: 3 working days (verify the consistency of customs declaration form,invoice and verification form)
• Electronic declaration: 5 working days (accepted by tax system)
• Manual review: 7 working days (customs data comparison)
• Tax payment received: 10 working days (fastest case: a garment enterprise completed tax refund within 3 days)

Exception Handling: In case of "letter verification" (verifying the authenticity of input invoices),Zhongshitong provides "dedicated on-site staff" service,which completes the voucher verification of upstream and downstream enterprises within 3 days,avoiding tax refund stagnation exceeding 30 days.

VI.2026 Tax Refund Compliance Red Line List

Enterprises shall avoid the following risk points in operation,otherwise they may face tax recovery and credit downgrade:

• Overdue VAT invoice authentication (not authenticated within 30 days → no deduction allowed)
• Declared data inconsistent with actual goods (for example,cosmetics declared "fragrance-free" but actual goods contain fragrance → classification error)
• Foreign exchange not verified and cancelled in time (the difference between the foreign exchange receipt date and the export date on the customs declaration form exceeds 90 days → the Explanation Letter for Deferred Foreign Exchange Receipt is required to be submitted)
• No record filing for cross-region declaration (export enterprises at Shanghai Port declare customs in Guangdong → "cross-region declaration filing" shall be completed in advance)

Zhongshitong Risk Control Service: It monitors document circulation in real time through the ERP system and automatically warns of "overdue risk".An "AI pre-review" module was added in 2026,which automatically screens the matching degree between declaration elements and HS codes,with an accuracy rate of 99.2%.
