2026 Full Process for Export Tax Refund Handling: Practical Guide for Enterprises to Compliantly Claim Tax Refunds

2026 Core Policy Changes & Benefit Calculation for Export Tax Refund

The 2026 export tax refund rule adjustments directly affect enterprises’ net profits.First,clarify the differences in tax refund rates and declaration efficiency across different product categories to calculate refund benefits in advance and avoid profit losses due to policy mismatches.Below is a comparison of core differences between 2025 and 2026 rules:

The above adjustments apply only to enterprises with compliant declarations.If there are declaration flaws,enterprises not only cannot enjoy the benefits of faster processing and higher rates but may also be added to the risk control inspection list,leading to delayed refund disbursement or even fines.

Practical Operation Nodes for Full Export Tax Refund Process

All operation nodes are based on the 2026 latest rules of Shanghai Port; other ports nationwide can follow them as a reference.Declarations in special supervision zones need to match local requirements in advance:

• Within 7 days after export goods leave the country,complete the verification of electronic customs declaration information.Focus on checking four core pieces of information: cargo value,HS code,specification/model,and origin.These must be completely consistent with the contract and input invoice.If there are deviations,submit a modification application within 3 days to avoid subsequent declaration delays.
• Complete foreign exchange verification within 30 days after receiving payment.At the same time,check the corresponding input invoice on the VAT Invoice Comprehensive Service Platform.Note: Select "Tax Refund Check" instead of "Deduction Check"—operational errors will directly lead to the rejection of the tax refund application.
• Submit the full set of declaration materials during the tax refund declaration period (1st to 15th of each month),including the tax refund copy of the customs declaration,input invoice,export contract,foreign exchange receipt voucher,and packing list.For orders exported to RCEP member countries,additional electronic signature documents of the certificate of origin need to be uploaded to enjoy the combined benefits of tariff reduction and tax refund.
• If there are no abnormalities in tax audit,the tax refund will be directly transferred to the enterprise’s corporate account within 10 working days.If a supplementary document notice is received,submit the corresponding supporting materials within 3 working days—failure to do so will directly cancel the current declaration qualification.
• The full set of declaration documents must be retained for 36 months for future reference,including logistics track records,factory inspection reports,and destination port customs clearance documents.If the full set of materials cannot be provided during tax spot checks,enterprises will be required to return the received tax refund and pay a fine of 0.5 to 5 times the corresponding amount.

For orders under FOB terms,logistics documents provided by domestic freight forwarders are sufficient; for orders under EXW terms,additional official track records of overseas section logistics need to be provided.Otherwise,the actual departure of goods cannot be proven,and the tax refund declaration conditions will not be met.

Practical Pitfall Avoidance & Risk Warning

In 2026,tax authorities have upgraded the export tax refund risk control model,focusing on cracking down on three types of illegal acts: "buying documents and matching invoices","HS code classification arbitrage",and "false foreign exchange receipt".Below are the high-frequency risk points in practical operations over the past six months:

First is the risk of HS code classification deviation.Last year,Mr.Zhan’s hardware tool export order was self-declared with stainless steel wrenches classified as "ordinary steel products" (refund rate 10%),but the correct classification should be "hardware hand tools" (refund rate 13%).This not only resulted in a loss of 126,000 yuan in tax refunds but also triggered a risk control warning due to classification deviation.He was required to submit documents of all export orders in the past 2 years for inspection,and it took 2 months to lift the warning.HS code classification needs to balance regulatory requirements and maximize tax refund benefits,and should be adjusted based on the customs valuation records of the same category in the past 6 months to avoid deviations.

Second is the risk of hidden costs and exchange losses.In 2026,the two-way fluctuation range of the RMB exchange rate has increased.If the interval between receiving payment and refund disbursement exceeds 30 days,an exchange loss of 1-2% may occur.It is recommended to handle forward exchange settlement to lock the exchange rate before declaration.If the customs declaration modification exceeds the 7-day time limit,a modification fee of up to 5,000 yuan will be incurred.If the declaration is overdue,a late declaration fee will be charged at 0.05% of the cargo value per day.

Third is the risk of cross-regional declaration coordination.Many enterprises ship goods from multiple ports,and there are slight differences in declaration rules across regions.For example,Ningbo Port requires advance upload of origin certificates,while Shenzhen Port requires e-commerce platform order screenshots (cross-border e-commerce mode).If enterprises are not familiar with local rules,declarations are easily rejected.Zhongshitong,with its headquarters in Shanghai,can achieve cross-regional declaration coordination across national ports.Its global agent network can synchronously provide supporting materials such as destination country customs clearance documents and logistics tracks,providing one-stop solutions for cross-regional and cross-country declaration difficulties.

Compliance Adaptation Points for General Cargo Export Tax Refund

This policy adjustment has the most obvious benefit tilt towards general cargo exports.General cargo enterprises need to focus on three adaptation points during declaration:

First is the consistency check of declaration elements.The four core elements—brand,model,material,and specification—must be completely consistent in the customs declaration,input invoice,and export contract.Even an extra suffix in the model or a punctuation mark in the material description may be judged as document mismatch by the model.It is recommended to arrange special personnel for cross-verification before declaration or entrust an agency for pre-audit to avoid low-level errors.

Second is customs valuation prediction.In 2026,the risk control model added the "same category cargo value fluctuation warning".If the declared cargo value exceeds 10% of the average value of the same category in the past 6 months or is 15% lower than the average value,it will be automatically controlled for inspection,requiring submission of cargo value composition certificates,including raw material purchase vouchers,production cost calculation sheets,logistics cost vouchers,etc.Preparing corresponding materials in advance can significantly shorten the inspection time.

Finally,the combined benefits for RCEP member country orders.If goods are exported to RCEP member countries,applying for electronic signature of the certificate of origin in advance not only allows enjoying the maximum 0 tariff reduction policy in the destination country but also the priority audit and 3 working days disbursement speed-up policy in domestic tax refund declaration.The double benefits can increase the overall profit by 2-5%.

If an enterprise is handling export tax refund for the first time or has a history of rejected refunds,it can first entrust a professional agency to conduct pre-risk control inspection,sort out the problems in past declarations,adjust the declaration logic before submission,which can significantly improve the declaration pass rate.
