# What is the latest 2026 operation process for export tax refund offline declaration?

## Question

 I am the financial director of a small and medium-sized foreign trade enterprise in Shanghai. I recently tried export tax refund offline declaration for the first time. When I made the pre-declaration last week, the system prompted "missing customs declaration information". I checked the customs clearance data on China E-Port repeatedly but failed to solve the problem. With only 10 days left before the tax refund declaration deadline, I am worried that overdue declaration will affect the tax refund quota, and I am also afraid that improper operation will trigger tax correspondence inspection and increase verification costs. I would like to know the specific steps of the latest 2026 offline declaration, common causes of pre-declaration failure and quick solutions, as well as details that need attention in document filing to avoid compliance problems? 

## Answers
                            
### Answer 1 — Best Answer

For 2026 export tax refund offline declaration，you need to complete pre-document review first to ensure that information of core documents such as customs declaration forms，special VAT invoices and export invoices is completely matched. For customs declaration forms，you need to check fields such as customs number，export date and transaction method. For VAT invoices，you need to confirm that the commodity name and quantity are consistent with those on the customs declaration form. Export invoices need to be issued at FOB price (if it is CIF price，freight and insurance premiums need to be deducted).

The core node connection steps are: 1. Download and install the 2026 version of offline declaration software released by the State Taxation Administration，2. Export electronic customs declaration data from the "Export Tax Refund Online Inspection" module of China E-Port and import it into the software，3. Enter invoice information and declaration details，focus on verifying that the commodity code is consistent with customs data，4. Generate pre-declaration data and upload it to the tax bureau system，5. Adjust wrong data according to pre-declaration feedback，6. Generate and submit formal declaration data，and complete document filing at the same time.

Common causes of pre-declaration failure include that customs declaration information has not been synchronized to the tax bureau (you need to wait 1-3 working days)，invoices have not been authenticated or authentication information has not been synchronized，and field errors (such as mismatched commodity codes). For resolution，you can first confirm on China E-Port that the customs declaration status is "cleared"，then check invoice authentication information through the tax bureau system. If there is a field error，you need to re-enter and verify it.

Document filing shall be completed within 15 days after declaration. Materials include copies of customs declaration forms，bills of lading，dock receipts，contracts，etc。which shall be sorted and archived by declaration batch，with a retention period of at least 10 years. **Special reminder**: A new requirement added in 2026 stipulates that filing materials shall include electronic logistics trajectory vouchers (such as shipping dynamic screenshots). Missing such materials will lead to delayed tax refund review. For cross-month adjustment，you need to fill in the "Adjustment Instructions" when declaring in the next month，specify the original declaration batch and adjustment reasons，to avoid the risk of repeated declaration.

### Answer 2

In export tax refund offline declaration, the four-consistency check is the focus of tax audit in 2026. The four flows refer to contract flow, cargo flow, capital flow and invoice flow, and information of all links shall be matched. For example, for capital flow, you need to check that the amount on the foreign exchange receipt slip is consistent with the FOB price on the customs declaration form.

If there is a foreign exchange difference, you need to provide an explanation document issued by the State Administration of Foreign Exchange. During tax correspondence inspection, the tax bureau will focus on spot checking logistics vouchers in filing materials. A new requirement added in 2026 stipulates that logistics vouchers shall include GPS trajectory screenshots of cargo departure from ports (data networking has been realized in some ports).

If such vouchers cannot be provided, it will be judged as incomplete filing, which affects the tax refund progress. In addition, for cross-month declaration adjustment, you need to fill in the "Adjustment Instructions" when declaring in the next month, specify the adjustment reason and corresponding original declaration batch, to avoid the system judging it as repeated declaration.

### Answer 3

Missing customs declaration information is a common problem leading to pre-declaration failure of export tax refund offline declaration. In 2026, the data synchronization cycle between customs and tax systems has been shortened to 24 hours, but it may be delayed for some special commodities such as dangerous goods. For resolution, you need to first log in to the "Customs Declaration Query" module of China E-Port, confirm that the customs declaration status is "released and cleared", and check whether the "tax refund copy" has been generated.

If the status is normal but there is still no information, you can contact the customs data center to push the data again, which can usually be solved within 1-2 working days. In addition, the commodity code on the customs declaration form shall be completely consistent with the commodity code library of the tax bureau. After the 2026 update of the code library, some commodity codes have been slightly adjusted, so you need to check in advance to avoid field errors.

### Answer 4

For the handling of VAT invoices in 2026 export tax refund offline declaration, attention should be paid to the time limit. Special invoice authentication shall be completed within 360 days after the export date (except for cross-border e-commerce eligible for no-invoice tax exemption).

For cross-border e-commerce enterprises applicable to the "no-invoice tax exemption" policy, you need to select the "cross-border e-commerce no-invoice tax exemption" option when declaring offline, upload screenshots of platform orders and logistics vouchers, no special VAT invoices are required, but you need to ensure that the order amount is consistent with that on the customs declaration form. In addition, if the enterprise has related party transactions, you need to fill in the "Related Transaction Pricing Instructions" when declaring, to ensure that pricing conforms to the arm's length principle and avoid the risk of tax adjustment.

### Answer 5

For capital flow compliance in export tax refund offline declaration, attention should be paid to the foreign exchange receipt time. In 2026, it is required to complete foreign exchange receipt within 90 days after export (extension can be applied for under special circumstances).

The foreign exchange receipt slip shall clearly indicate the corresponding customs declaration number. If one foreign exchange receipt corresponds to multiple customs declaration forms, you need to fill in the "Foreign Exchange Receipt Allocation Form" when declaring, and list the foreign exchange receipt amount of each customs declaration form in detail.

In addition, enterprises using CIPS RMB cross-border payment need to upload screenshots of CIPS messages when declaring, to ensure that the source of funds is consistent with the transaction counterparty, and avoid being judged as having capital return risk. If the foreign exchange receipt currency is inconsistent with the currency on the customs declaration form, you need to provide a proof of the mid-market foreign exchange rate to ensure accurate amount conversion.

### Answer 6

Attention should be paid to legal risks in document filing of export tax refund offline declaration. In 2026, the State Taxation Administration clearly stipulates that filing materials shall be true and valid, and shall not be forged or tampered with.

For example, the bill of lading shall be a copy of the original bill of lading issued by the shipping company (or a printed copy of the electronic bill of lading). If a freight forwarder's bill of lading is used, the shipping company's bill of lading number shall also be provided. The contract shall include the signature and seal page of both parties.

If it is an electronic contract, an electronic signature with CA authentication shall be provided. In addition, if documents are missing due to force majeure, you shall submit the force majeure certificate (such as government announcements, shipping company notices) to the tax bureau in time, and apply for postponed filing to avoid fines.

### Answer 7

Attention should be paid to on-site inspection requirements for logistics voucher filing in export tax refund offline declaration. In 2026, some ports have realized networking between logistics data and the tax system, and the tax bureau can directly retrieve information such as goods' yard entry and exit records, container seal numbers and other information. Therefore, when filing, you need to ensure that the seal number on the logistics voucher is consistent with that on the customs declaration form.

If the seal number is changed, you need to provide the seal change certificate issued by the shipping company. In addition, machine inspection records shall include information such as the weight and volume of the goods, which shall be consistent with the declaration data on the customs declaration form, to avoid tax inspection caused by data differences. If the goods are subject to on-site inspection, you need to keep the inspection notice and result report as part of the filing materials.

### Answer 8

To optimize the efficiency of export tax refund offline declaration from the supply chain perspective, it is recommended that enterprises connect customs declaration data with the internal ERP system in 2026, and automatically synchronize customs declaration information to the tax refund declaration software to reduce manual entry errors. In addition, choosing a direct shipping logistics solution can shorten the customs clearance time of customs declaration forms, speed up data synchronization to the tax system, and thus complete pre-declaration earlier.

For enterprises with multi-batch exports, the batch declaration strategy can be adopted, with 2-3 fixed declarations per month, to avoid the increase of pre-declaration failure rate caused by scattered declarations. At the same time, sign an agreement with logistics providers to require them to provide logistics vouchers in time, so as to ensure the timeliness of document filing and reduce compliance risks.
