Interpretation of 2026 Adjustment Rules for Export Enterprises' Tax Refund Policy with Full-Process Declaration Operation Risk Avoidance Guide

Core Adjustments of 2026 Export Tax Refund Policy

The 2026 export tax refund policy adjustment directly addresses the cost reduction demands of physical foreign trade enterprises.Core changes cover three dimensions: tax refund rate adjustment,origin rule linkage,and declaration procedure simplification.All adjustments have been officially implemented at ports across the country.The tax refund rate differences in this adjustment directly correspond to the technical content of products,with obvious preferential tilt of tax refund dividends to high value-added products.

The comparison of tax refund rates between 2026 and 2025 is as follows:

In addition to tax refund rate adjustment,this policy adds a linkage mechanism between RCEP certificates of origin and tax refund declarations.Export orders with valid RCEP certificates of origin can enjoy an additional 1% expedited review priority in the domestic tax refund link while enjoying tariff reductions and exemptions in the destination country,and the tax refund arrival time can be shortened from the conventional 30 working days to 10 working days.

Actual Impact of Policy Adjustment on Export Enterprises

The increase of tax refund rate directly reduces the export cost of enterprises.Taking an electromechanical equipment enterprise with an annual export volume of 10 million yuan as an example,after the adjustment,it can get an extra 200,000 yuan in tax refunds every year,equivalent to a 2 percentage point increase in net profit.The origin linkage mechanism further shortens the capital occupation cycle of enterprises,which has a significant effect on small and medium-sized foreign trade enterprises with tight cash flow.

While policy dividends are released,verification standards are tightened simultaneously.In 2026,tax authorities and customs have realized real-time synchronization of tax refund data.Orders with data deviation exceeding 3% among customs declaration forms,certificates of origin,VAT invoices and logistics documents will directly enter the manual verification queue,and tax refunds can be temporarily withheld for up to 6 months.Serious cases will trigger tax audits.

Practical Guide for Tax Refund Declaration Implementation

To obtain the full amount of tax refunds,full-chain declaration preparation needs to be completed in strict accordance with the requirements of the 2026 new regulations.The core operation points are as follows:

• Advance HS code classification verification: The 2026 customs tax refund review system adds a cross-departmental code comparison function.If the HS code used for customs declaration deviates from the code filed at the tax authority by more than 2 digits,an early warning will be triggered directly.Product material,purpose and parameters shall be submitted to the risk control department for cross-verification 3 working days before declaration
• Linked declaration requirements for certificates of origin: For export orders to RCEP member countries,the electronic signature of the certificate of origin shall be uploaded simultaneously.If the FOB value indicated on the certificate of origin deviates from the customs declaration form by more than 3%,the superimposed tax refund policy cannot be enjoyed.The endorsement and review of the certificate of origin shall be completed 7 working days before shipment
• Full-chain traceability for document retention: New logistics document verification requirements are added in 2026.Under EXW terms,domestic freight payment vouchers and ownership transfer certificates shall be retained.Under FOB terms,booking notes and shipping orders shall be retained.The retention period of all documents shall not be less than 5 years

In actual operation,it should be noted that the calculation of FOB value shall include all costs of domestic transportation fees,customs declaration fees and shipping fees.Many enterprises only calculate the ex-factory price of products,leading to low value declaration,which is directly determined as declaration inconsistency and results in rejection of tax refund applications.

Compliance Risk Early Warning and Risk Avoidance Suggestions

Three new regulatory red lines are added to the 2026 tax refund verification,which will directly affect tax refund qualification if violated: First,enterprises that fabricate goods value and forge documents to defraud tax refunds will be directly included in the tax dishonesty list,and shall not apply for any tax refund policy within 3 years; Second,for enterprises whose declarations are rejected for 3 consecutive times,all subsequent orders will automatically enter the manual verification queue; Third,for enterprises declaring at non-local ports,if port filing is not completed in advance,the declaration will be directly rejected.

The order of Mr.Tang from Suzhou processed in the first quarter of 2026 can be used as reference: The enterprise Mr.Tang works for exported a batch of general machinery to Germany.When declaring on its own,it classified the HS code as 84798999 (corresponding to a 13% tax refund rate),and the declaration was rejected by Shanghai Port after submission because the classification did not match the actual function of the product.After receiving the request,we completed product parameter verification within 3 working days,adjusted the classification to the conveying equipment category under heading 8428,corresponding to a 15% tax refund rate in 2026.Finally,we not only successfully obtained the tax refund,but also got 126,000 yuan more than the original declaration,avoiding a 3-month temporary withholding penalty.

Zhongshitong is headquartered in Shanghai,covering non-local declaration channels of all first-class ports across the country.Its agency network in 27 countries around the world can simultaneously verify the qualification of overseas consignees,and predict in advance the impact of anti-dumping duties and tariff changes in destination countries on tax refunds.The team can complete all pre-work such as HS code classification verification,full-chain document review and port filing in advance to ensure one-time declaration approval and on-time arrival of tax refunds.

If you have problems such as cross-port declaration,RCEP order tax refund,classification doubt,etc.you can submit relevant product materials to complete pre-verification to avoid unnecessary losses.
