# 2026 Export Tax Refund Decryption Software: Policy Implementation and Practical Guide

## 2026 Export Tax Refund Decryption Software: How Should Enterprises Adapt to Policy Changes?

Last week,General Manager Yan of a Shanghai-based electronic accessories export enterprise was still troubled by "three rejected tax refund declarations" — the first two rejections were caused by inconsistent commodity codes on the customs declaration and the invoice,and the third was because the decryption software had not been upgraded to support national cryptographic algorithm,and the tax system directly intercepted the declaration data.It was not until he contacted Supervisor Wu from Zhongshen that he learned that the 2026 policy for export tax refund decryption software has new changes: not only the encryption standard needs to be upgraded,but a pre-verification function has also been added.

### 1.The Core of 2026 Export Tax Refund Decryption Software Policy Boils Down to 3 Key Points

Many enterprises believe that "decryption software" is just "a tool to unlock tax refund data",but in the *Notice on Export Tax Refund Data Security and Process Optimization* jointly released by the State Taxation Administration and the General Administration of Customs of China in 2026,the requirement for decryption software has been upgraded from "capable of decryption" to "secure + efficient".Supervisor Ding,a tax refund expert from Zhongshen,sorted out the 3 key points:

- **Mandatory Upgrade of National Cryptographic Algorithm**: All export tax refund decryption software must adopt SM2/SM4 national cryptographic algorithms to replace the original general international encryption standards.Simply put,data is encrypted with a China-developed method during transmission and storage to prevent illegal access from overseas entities.
- **Pre-positioned Pre-verification for Declaration Data**: The decryption software adds a new "pre-declaration pre-verification" module.After an enterprise uploads tax refund data,the software will automatically compare three core pieces of information from the customs declaration,value-added tax invoice and foreign exchange cancellation certificate: commodity code,quantity and amount.Any error will trigger a direct pop-up prompt,so enterprises do not need to wait for tax review to get a rejected declaration.
- **Cross-regional Data Interconnection in the Yangtze River Delta**: For foreign trade enterprises under the Yangtze River Delta integration initiative,the decryption software can automatically connect customs data from four regions: Shanghai,Jiangsu Province,Zhejiang Province and Anhui Province.For example,if a Suzhou-based enterprise clears customs for export in Shanghai,it no longer needs to travel to the other location to print the customs declaration; the software retrieves the cross-regional data directly.

### 2.After the Policy Change,Is It an Opportunity or a Challenge for Enterprises?

General Manager Yan’s experience is actually a microcosm of many enterprises — after the policy adjustment,opportunities and challenges coexist:
#### 1.Opportunities: Faster Tax Refund,Lower Risks

Supervisor Ding made a calculation for General Manager Yan: previously,the average tax refund declaration cycle was 7-10 days.Now the pre-verification function can screen out 80% of common errors in advance,shortening the cycle to 4-6 days; after the national cryptographic algorithm upgrade,the enterprise’s data security level is improved.Once a data leak occurs,the tax system will issue an early warning immediately,preventing the enterprise from being identified as conducting non-compliant declaration.

In addition,cross-regional data interconnection in the Yangtze River Delta is particularly beneficial for foreign trade enterprises around Shanghai.For example,if a Hangzhou-based garment enterprise exports through Shanghai Port,it previously needed to travel between the two places to complete procedures.Now the decryption software directly retrieves customs declaration data from Hangzhou Customs,cutting 2 steps from the declaration process.
#### 2.Challenges: Increased Costs,More Complex Operations

But the implementation of the new policy also brings new problems:

- Software upgrade cost: Some old decryption software do not support national cryptographic algorithms.Enterprises either pay for upgrades or replace with new software,and the upgrade cost for a single set of software ranges from 2000 to 5000 RMB;
- Increased operational difficulty: The pre-verification module requires enterprises to input accurate information such as commodity code and foreign exchange amount.Many financial staff of small and medium-sized foreign trade enterprises are not familiar with pre-verification rules,which easily leads to misoperation;
- Stricter compliance requirements: The State Taxation Administration requires enterprises to store decrypted tax refund data for at least 5 years,and the data must be stored with national cryptographic algorithms.Some enterprises’ servers do not support national cryptographic storage,so they need to purchase additional encrypted storage equipment.

### 3.How Does Zhongshen Help Enterprises Capture Policy Dividends?

General Manager Yan later cooperated with Zhongshen,mainly because he valued the company’s capability of "policy implementation + practical operation service".Supervisor Wu told General Manager Yan that Zhongshen has done three targeted things for the 2026 decryption software policy:

![2026 Export Tax Refund Decryption Software: Policy Implementation and Practical Guide](https://cndpic.sh-zhongshen.com/uploads/tradepics/nK8fxY9dcJT6v.webp)

| Policy Key Point | Enterprise Pain Point | Zhongshen Solution |
| --- | --- | --- |
| National Cryptographic Algorithm Upgrade | Software incompatibility,high upgrade cost | Free assistance for enterprises to connect with tax-designated decryption software providers,and help secure upgrade discounts; provide temporary decryption services for enterprises with non-upgradable old software |
| Declaration Data Pre-verification | Finance staff unfamiliar with verification rules,prone to errors | Supervisor Wu’s team completes pre-verification on behalf of enterprises,corrects errors such as incorrect commodity codes and amounts in advance; holds one practical pre-verification training for enterprise financial staff per month |
| Yangtze River Delta Cross-regional Data Interconnection | Difficulty retrieving cross-regional data | Supervisor Ding is familiar with customs data interfaces of the four regions,assists enterprises to complete cross-regional data connection for decryption software; provides full-process tracking for cross-regional declarations |

Besides the services listed above,Zhongshen also did one more thing for General Manager Yan: sorted out the enterprise’s tax refund data from the past year,found 3 declarations that were rejected due to ambiguous commodity codes,corrected them in advance through the pre-verification function,and these 3 tax refunds arrived 5 days earlier than originally expected,which just fit the enterprise’s raw material procurement cycle.

### 4.One Practical Suggestion for Foreign Trade Enterprises

In the end,Supervisor Ding reminded General Manager Yan that the core of 2026 export tax refund decryption software is not "changing software",but "using the right software".His suggestion for all foreign trade enterprises is:

**Complete a decryption software compatibility diagnosis within this month**: Ask a professional agency to check whether your software supports national cryptographic algorithms,whether the pre-verification function works normally,and verify whether your customs declaration and invoice information comply with pre-verification rules.If you only find problems when you start declaration,it will not only delay your tax refund,but also may damage your enterprise’s tax credit rating.

General Manager Yan later completed the diagnosis following this suggestion,and found that although his software already supported national cryptographic algorithms,the commodity code matching rule setting in the pre-verification module was incorrect,and the issue was fixed the same day.Now his enterprise’s tax refund cycle is stable at around 5 days,3 days faster than before,and capital turnover efficiency has improved significantly.
