2026 Complete Practical Guide to Sunny Compliance for Export Tax Refund Agencies

Core Policy Background of Sunny Compliance for Export Tax Refund Agencies 2026

In 2026,the General Administration of Customs and the State Taxation Administration jointly issued the Detailed Rules for Compliance Management of Export Tax Refund Documents,which clearly stipulates that agencies shall bear joint liability for the authenticity of declared data and consistency of documents.This has made many small and medium-sized foreign trade enterprises aware of the urgency of sunny compliance.As the largest foreign trade port in China,Shanghai Port recorded a 12% year-on-year increase in tax refund inspection rate in 2026,with 62% of tax refund delay cases caused by compliance loopholes.

Policy Interpretation: Three Non-negotiable Red Lines

• HS code classification error: The customs price review model was upgraded in 2026,and classification deviation exceeding 5% will directly trigger targeted inspection.The inspection rate for some mechanical,electrical and chemical products is as high as 89%
• Inconsistency between documents and actual goods: Discrepancies between declared elements such as brand,model,material and actual goods will be identified as suspected tax fraud,and the involved enterprise will be added to the joint punishment list of the State Taxation Administration
• False trade background: Obtaining tax refunds through non-genuine customs declaration under other entities’ names,falsely issuing VAT invoices and other illegal means will lead to 3-5 years of suspension of tax refund qualification,alongside criminal liability investigation

Key Practical Implementation Points for Sunny Compliance of Export Tax Refund Agencies

Many enterprises assume tax refund only requires submitting documents,which is not the case.2026 compliance requirements mandate agencies to intervene from the source and cover the full process chain.

1.Accurate HS Code Classification and Price Review Pre-judgment

Shanghai Port’s 2026 inspection rate rose 12% year-on-year,with classification errors accounting for 47% of total cases.Zhongshitong’s operation team conducts classification in accordance with the 2026 Import and Export Tariff,combined with the actual use,material and processing technology of goods,while pre-judging key points of customs price review in advance,such as the proportion of imported components for mechanical and electrical products,component proportion for chemical products,etc.to avoid tax refund cycle delays caused by price review.In 2025,a Suzhou-based hardware export enterprise was placed under customs inspection due to incorrect HS code classification.After receiving the entrustment,Zhongshitong immediately retrieved the goods’ physical test reports and production process documents,reclassified the HS code,and submitted defense materials to the customs.The verification was finally completed within 15 working days,and the full tax refund was transferred to the enterprise’s account.

2.Full-chain Document Review and Risk Screening

In 2026,the State Taxation Administration requires tax refund documents to be retained for more than 5 years,and each document must correspond to genuine trade activities.Zhongshitong’s risk control team verifies the consistency of contracts,invoices,bills of lading and packing lists one by one,and checks whether the endorsement of certificates of origin meets the requirements of destination countries.For example,certificates of origin for RCEP member states must comply with the 2026 updated standards,and official certification documents are required for anti-dumping duty declarations for European and American countries.

3.Linked Compliance of Foreign Exchange Settlement and Tax Refund

In 2026,the State Administration of Foreign Exchange linked tax refund declaration with foreign exchange receipt and payment,requiring enterprises to complete foreign exchange verification before submitting tax refund declarations.Zhongshitong assists enterprises in selecting compliant settlement channels,avoiding underground banks or third-party collection agents,while updating foreign exchange declaration data simultaneously to ensure full matching between tax refund documents and foreign exchange data.For different trade regions such as Europe,America and the Middle East,Zhongshitong plans settlement cycles in advance to avoid foreign exchange receipt delays caused by holidays that may affect tax refund progress.

Compliance Risk Early Warning and Pitfall Avoidance Guide for Export Tax Refund Agencies

• Stay alert to low-cost agency traps: Some agencies attract customers with low rates,but obtain tax refunds through falsely issuing documents and forging trade backgrounds,which eventually leads to enterprises being added to the dishonest list.127 small and medium-sized foreign trade enterprises had their tax refund qualifications suspended for this reason in 2026
• Avoid off-site declaration blind spots: National port networked verification was implemented in 2026,and the document review cycle for off-site declaration is 30% longer than local declaration.Zhongshitong’s national port linkage system enables rapid review of off-site declarations,eliminating the need for enterprises to travel between different regions
• Do not ignore holiday-related customs clearance delays: For example,during the Christmas season in Europe and America and Ramadan in the Middle East,port inspection efficiency drops by more than 35%,so declaration time should be adjusted 7-10 days in advance to avoid overdue tax refund
