Recently, many cross-border e-commerce sellers have received notices from the platform that the platform will directly assume the responsibility of withholding corporate income tax for the sellers.
Some platforms represented by SHEIN have started small-scale pilots, mainly targeting sellers with full hosting models.
This is a landmark event in the cross-border e-commerce industry, marking that China’s cross-border e-commerce has officially entered the compliance deep water zone of “platform withholding + tax transparency”, and cross-border e-commerce tax compliance has entered a new stage of “platform co-governance”.
1. Platform withholding tax: from industry trends to compliance necessity
1. From “barbaric growth” to “system co-construction”
It has become the norm around the world: SHEIN is not the first cross-border e-commerce platform to provide tax withholding services.
As early as January 1, 2026, Amazon will implement a maximum 16% value-added tax and 20% corporate income tax withholding for its local site sellers in accordance with Mexican tax laws.
On the one hand, the platform realizes the connection between transaction data and the tax system through technical means, improving the efficiency of collection and administration; on the other hand, it also lowers the compliance threshold for small and medium-sized sellers – many small and micro sellers who lack professional financial and taxation teams will therefore avoid tax risks caused by omissions and misreporting.
With the full implementation of the “Regulations on the Submission of Tax-related Information for Internet Platform Enterprises”, the “tax blind spots” of the platform economy are rapidly disappearing.
In addition to SHEIN, mainstream cross-border e-commerce platforms such as Temu, AliExpress, and TikTok Shop are also expected to launch similar payment mechanisms.
This is not just a matter of tax collection, but also a reshaping of the industry ecology.
Policy compliance pressure: This is not a spontaneous behavior of the platform, but an inevitable result of the tightening of national tax supervision.
Policy basis: In June 2025, the State Council issued the “Regulations on the Submission of Tax-Related Information by Internet Platform Enterprises” (Announcement No. 15 of 2025), which clearly requires e-commerce platforms to submit the identity and income data of operators within the platform to the tax authorities.
In July of the same year, the State Administration of Taxation officially included cross-border e-commerce export business within the scope of corporate income tax collection and administration.
Level playing field: In the past, sellers operating in compliance had high costs (paying taxes), while non-compliant sellers had low costs (tax evasion), resulting in “bad money driving out good money”.
Platform deductions can eliminate this unfairness.
In July, the State Administration of Taxation issued the “Announcement on Optimizing Prepayment of Corporate Income Tax Declarations” (Announcement No. 17 of 2025), which requires production and sales companies exporting goods to declare corporate income tax on their export income in accordance with the law.
Announcements No. 17 and 15 jointly build a regulatory system covering “goods flow – capital flow – information flow”.
It marks that cross-border tax supervision has entered a new era characterized by cross-reference of “platform data + customs data + bank data”.
Compliance for cross-border e-commerce companies is no longer about “remedial action after the fact”, but should enter the daily operation process: Only by making the voucher chain, platform data and accounts “available at any time” can risks be minimized.
Synchronized global trends: Amazon and other international giants have already implemented withholding in many countries (such as Mexico, India, etc.).
SHEIN’s move is also to align with international tax regulatory standards.
Changing role of the platform: The platform has transformed from the original “dealmaker” to the “co-governor of tax compliance” and must assume the legal responsibilities of information reporting and tax withholding.
The pilot projects of platforms such as SHEIN are a positive response to this policy.
2. Interpretation of core policies: withholding mechanism and scope
This policy is not SHEIN’s “whim”, but a response to the relevant policies of the State Administration of Taxation in 2025 (such as the “Announcement on Optimizing Matters Related to the Prepayment of Corporate Income Tax Declaration”) No. 17 of 2025.
Its core mechanism is as follows:
Nature of withholding: The platform will serve as the withholding agent, deducting corporate income tax directly from the seller’s sales revenue, and reporting and paying it to the tax authorities uniformly.
Seller Rights (Options): This is not completely mandatory.
Sellers can choose to accept platform withholding, or they can choose to “give up payment” and go to the tax bureau to declare on their own.
Key difference: If you choose withholding: It saves you worry and effort, no need to declare again, but the profit will be directly reduced (the tax will be deducted from the repayment).
According to the instructions released by SHEIN, the platform will uniformly handle the corporate income tax settlement of export sales income for sellers. The tax will be directly deducted from subsequent repayments, and sellers do not need to make repeated declarations or pay additional taxes.
If you choose to declare on your own: the platform will still submit your real sales data (flow) to the tax authorities.
This means that it is almost impossible for you to “hide income” and you must produce compliant customs declarations and cost invoices to respond to tax inspections.
Current scope of application: According to the current leaked information, this service is mainly aimed at sellers in SHEIN’s fully managed model. Semi-managed sellers are not affected for the time being (but may be expanded in the future).
Currently, the platform’s customer service has been vague in its response to the specific withholding ratio, saying only that it will be calculated based on export sales and operated in strict accordance with laws and regulations.
There are two main speculations in the market: Common speculation ratio: Most analysts believe that the withholding ratio may be around 1% – 2% of sales.
This is regarded as a simplified assessment and collection method (not sure, please refer to the relevant documents of the tax authorities or further notice). For small and medium-sized sellers who lack professional financial and taxation capabilities, it is equivalent to purchasing a “compliance ticket.”
Preferential policy expectations: If the seller chooses to declare on his own and meets the conditions of a small and micro enterprise, the actual tax burden may be as low as 5% (based on profits rather than sales).
However, it should be noted that self-declaration requires a complete cost invoice and customs declaration form, and the compliance threshold is higher.
2. Specific impacts on sellers and countermeasures
Faced with this change, different types of sellers need to adopt different strategies:
1. For small and medium-sized sellers (no ticket/no customs declaration form):
For small and medium-sized sellers who have difficulty obtaining compliance certificates such as “customs declaration forms”, choosing a platform to pay on their behalf is a cost-effective “compliance insurance”.
Although the cost of 1% – 2% compresses the gross profit, it provides relatively safe operation.
It not only solves the problem of corporate income tax, but may also be regarded as a compliant export behavior, thus meeting the prerequisites for enjoying the preferential VAT “exemption and refund” policy and avoiding greater tax risks.
If you choose to declare on your own, you will face the risk of back taxes, late payment fees and even fines for unexplained turnover in the face of the fourth phase of the Golden Tax and the data reported by the platform.
Note: When a seller evaluates whether to use the platform’s corporate income tax withholding service, the core decision-making basis should not only consider the implementation cost or withholding ratio, but whether you can obtain legal export documents such as “customs declaration forms” to fundamentally avoid compliance risks.
2. For mature large sellers (with complete supply chain/cost invoice):
You can choose to declare yourself after evaluation.
For large sellers with professional finance and taxation teams who can ensure that all compliance certificates are obtained, self-declaration can optimize the overall tax burden under professional arrangements and is a more flexible option.
3. General suggestions:
Pay attention to backend notifications: Pay close attention to the “Income Query” tool and official announcements in SHEIN’s backend to check whether the data is accurate.
Sort out your financial situation: Whether withholding or not, make sure your accounts are clear.
Going forward, compliance is the only ticket to survival.
4 Long-term benefits: standardized development of the industry
Lower compliance thresholds: Platform withholding simplifies the tax operation process, especially for small and medium-sized sellers who lack professional financial and taxation knowledge, avoiding tax risks caused by omissions and misreporting.
Establish a fair environment: This move will help the entire industry develop in a more standardized and transparent direction and create a market environment for fair competition.
3. Core reminders and key points
Compliance is irreversible: Regardless of whether the seller chooses the platform to pay on behalf of the seller, the platform must submit its tax-related data to the tax authorities in accordance with the law.
Tax transparency is an irreversible trend.
Clear the boundaries of withholding services: What SHEIN withholds and pays this time is the “corporate income tax” corresponding to the income of the SHEIN platform. This means that the income that does not come from the SHEIN platform needs to be declared and paid by the seller to the tax authorities on its own and cannot be confused.
Pay attention to platform notifications: The specific withholding ratio, scope of application (currently mainly for fully managed sellers) and subsequent settlement rules need to be subject to the official notifications of the platform and relevant documents of the competent tax authorities.
Preserve financial information: Even if the platform withholds taxes on your behalf, sellers must properly keep all financial vouchers and transaction records. It is recommended to set up exclusive files and archive the settlement statements, deduction vouchers and other documents provided by the platform on a monthly basis. If there is a tax verification or dispute in the future, it will be prepared for verification by the tax authorities.
Don’t ignore the final settlement and payment: After the cross-border e-commerce platform withholds corporate income tax, the enterprise usually still needs to make the final settlement and payment, but there are special circumstances that can simplify or exempt the final settlement and payment obligations.
Cross-border e-commerce companies should pay close attention to the specific content of the platform’s withholding policy and the relevant regulations of the tax authorities, and communicate with the competent tax authorities in a timely manner to confirm whether final settlement is required.
Even if the platform withholds taxes, the company should properly preserve relevant financial information and tax vouchers for subsequent verification by the tax authorities.
In summary, SHEIN’s move is a landmark event for cross-border e-commerce to bid farewell to the “barbaric growth”.
In the future, the role of the platform will not only be a “dealmaker” but also a “compliance gatekeeper.”
Tax compliance capabilities, like logistics, payment, and marketing, may become a key indicator for measuring the comprehensive competitiveness of a platform.
Although the profit margins of some sellers will be compressed in the short term, in the long run, this is the only way for the industry to move toward formalization and sustainable development.
SHEIN’s online withholding service marks the shift from “back-end requirements” to “front-end implementation” of cross-border e-commerce tax supervision.
Tax compliance is no longer optional, but a prerequisite for survival and development.
For the entire industry, platform withholding and payment of taxes may become an irreversible trend.
At least, for now, it promotes the standardization and transparency of the industry’s overall operations, and sounds the clarion call for comprehensive tax compliance for cross-border e-commerce.
