in the wake ofPhase IV of the Golden Tax System Has Been Fully Implemented...Major cross-border e-commerce platforms such as Amazon and Temu now submit complete sets of sellers“ business data to tax authorities on a quarterly basis, marking a shift in cross-border e-commerce tax oversight from ”passive collection“ to a new phase of ”proactive verification.“ ”Tax avoidance” practices that once relied on information asymmetry are becoming increasingly difficult to conceal.

We recommend bookmarking this and sharing it with your partners and finance team.

Scenario 1: Incorrect Income Reporting-Filing Tax Returns Based on Net Cash Receipts; Long-Term Zero-Declaration

Common Errors

This is currently the number one risk area in early warning rankings. Many sellers report VAT based only on the net amount available for withdrawal—after deducting commissions, advertising fees, and FBA fees—rather than recording the full GMV paid by the buyer. For example, if a buyer actually pays $100 for an order and the seller receives $80 after the platform deducts its fees, the seller reports only $80, which directly results in a data discrepancy of 20%.

There are also some stores with monthly sales in the hundreds of thousands or millions that simply enter “0” for VAT and file a zero-report, confusing the concept of “export tax exemption reporting” with that of a zero-report. Furthermore, some sellers split their business across multiple stores to qualify as small-scale taxpayers, artificially keeping their annual sales below 5 million to avoid the 13.1% and 3% tax rates applicable to general taxpayers.

Regulatory Consequences

Amazon and Temu submit their total order amounts to the tax authorities on a quarterly basis. Discrepancies between reported amounts and platform data exceeding 5% trigger an automatic alert, while discrepancies of 30% or more result in an on-site audit.

🔷 The differenceReimburse the full amount of 13% VAT, plus a late payment penalty of 0.05 percent per day

🔷 Long-term filing of zero returns is deemed to be concealment of income and is subject toFines ranging from 0.5 to 5 times the amount of underpaid taxes

🔷 Combined revenue from multiple stores is used for tax calculation, and the amount exceeds the limitMandatory Upgrade to General Taxpayer Statusand pay back taxes retroactively

A cross-border company in Xiamen reported actual total exports of 228 million yuan for 2021–2022 but declared only 2,000 yuan on its books. Tax authorities compiled data from customs, banks, and logistics providers to establish a complete chain of evidence, resulting in a total of 10.78 million yuan in back taxes and fines. The case was referred to public security authorities.

Compliance Practices

Companies should prepare a comprehensive “Platform Revenue Reconciliation Statement” on a monthly basis, verifying at least the following data: order sales—refund amounts—discounts and subsidies—platform commissions—advertising expenses—warehousing and logistics costs—actual settlement amount—exchange rate differences—booked revenue—revenue reported for tax purposes.

Sales revenue and platform fees must be accounted for separately; you cannot base your bookkeeping solely on the amount withdrawn.

 Scenario 2: Platform Proceeds Deposited into a Personal Account(math.) genusLong-Term Off-Balance-Sheet Circulation of Corporate Funds

Common Errors

1. Funds from the platform are withdrawn directly to the personal accounts of the business owner, shareholders, or employees;
2. Using personal WeChat and Alipay accounts to collect business payments over the long term;
3. Payments to suppliers, shipping costs, and wages are all paid from a personal account;
4. There were frequent transfers of funds between the company and its shareholders, but no loan agreements, dividend payment records, or reimbursement documentation;
5. Multiple companies use the same individual account to pool funds;
6. Exchanging or converting foreign currency through unknown third-party accounts or unofficial channels.

In the early stages of a cross-border e-commerce startup, many business owners find company accounts inconvenient to use, so they simply transfer funds from the platform directly to the personal accounts of the legal representative, shareholders, or employees. Payments for purchases, shipping costs, employee salaries, and advertising credits are also all made from the owner’s personal account.

On the surface, the money is still being used for business operations; however, from a tax and financial perspective, the company has lost its complete cash flow chain.

The real danger isn't simply the amount itself, but rather:The personal account shows frequent transactions, with the source of funds not matching the individual’s identity, and there are clear links to the company’s platform revenue, reported income, and procurement expenditures.

Regulatory Consequences

Banks' anti-money laundering systems monitor private accounts with annual transaction volumes exceeding 500,000 and automatically notify tax authorities; all business-related income in private accounts is deemed off-the-books income, and VAT and corporate income tax are collected retroactively; penalties are imposed for foreign exchange violations, including restrictions on corporate foreign exchange conversion and the freezing of receiving accounts by banks; where the amount meets the threshold, criminal liability for tax evasion is pursued, and legal representatives face travel restrictions and credit rating impacts.

A major e-commerce platform in Shenzhen reported total revenue of 230 million yuan but declared only 170 million yuan on its books; the remaining 60 million yuan was collected entirely through personal bank accounts. Ultimately, the company was required to pay 95 million yuan in back taxes and fines, leading to its immediate bankruptcy.

Compliance Recommendations

Payments for platform settlements, procurement, advertising, employee salaries, and logistics expenses should be made through the company’s business bank account whenever possible.

If shareholders have indeed provided advance funds, loans, or made payments on behalf of the company, the following documents must be retained at the same time:

🔷 Shareholder Loan Agreement;

🔷 Expense Reimbursement Form;

🔷 Purchase contracts and payment documents;

🔷 Resolutions of the board of directors or the shareholders’ meeting;

🔷 Explanation of the Use of Funds;

🔷 Subsequent repayment or settlement records.

A business bank account isn’t just a “formality”—it’s meant to verify where the money came from, where it went, and why the transaction took place.

 Scenario 3: Export Invoices and Export Methods That Do Not Match the Actual Business Transactions

Common Errors

❎ A company does not have its own export customs declaration data but directly files for tax-exempt exports or tax refunds;

❎ The entity filing the customs declaration does not match the actual owner of the goods or the seller on the platform;

❎ Mixed use of 9610, 9710, and 9810; the business model does not match the regulatory code;

❎ Purchasing customs declaration forms through other companies or fabricating export transactions;

❎ Only logistics documents are available; there are no purchase contracts, export contracts, or sales documents;

❎ The descriptions and quantities of tax-refunded goods, customs-declared goods, and goods sold on the platform do not match.

Regulatory Consequences

There are no customs export records for this company, and it does not meet the statutory requirements for export tax exemption or tax refund; all export revenueRetroactive Payment of 13% Value-Added Tax Treated as Domestic Sales; The full amount of the advance tax refund claimed under Form 9810 has been recovered; the export transaction was classified as “four self-managed, three non-face-to-face,”Cases involving suspected fraud to obtain export tax rebates may be referred to the police.

In late 2025, the Shenzhen Customs launched a concentrated crackdown on “buy-in” exports, intercepting 127 cases of violations in a single operation, with the value of the goods involved exceeding 230 million yuan. Currently, the real-name registration system for export agents has been fully implemented, and the “buy-in” export model is no longer viable.

Compliance Practices

Before a company engages in tax-exempt or tax-refunded export activities, it should first confirm the following:

• Which type of export model does it actually fall under?;
• Who is the purchasing entity;
• Who is responsible for customs clearance?;
• Who is the primary seller on the platform?;
• Who is responsible for collecting payments;
• At which stage does ownership of the goods transfer?;
• Whether complete input invoices and export documents are available.

Exporting companies should also maintain records of purchase and sales contracts, shipping documents, customs clearance agency agreements, invoices for customs clearance service fees, platform sales details, overseas warehouse inventory records, and sales accounting vouchers.

 Scenario 4: Hong Kong Shell Companies Diverting Profits(math.) genusCRS+CFC Triple Accountability

Common Errors

A mainland-based actual controller holds shares in a Hong Kong-based collection company,Do not file an ODI overseas investment registration;Hong Kong companies have no local office or employees, do not maintain accounting records or undergo audits on a regular basis, and leave Amazon proceeds sitting in offshore accounts indefinitely without distributing dividends; 90% or more of the profits are retained in Hong Kong, while the mainland operating company consistently reports minimal profits or losses, artificially shifting profits to evade taxes; the actual controller of the Hong Kong company is concealed, and tax residency status is falsely reported to circumvent CRS information exchange.

Regulatory Consequences

Failure to Register with the ODI: Penalty equal to the investment amountA fine of 1‰ to 10‰
, a ban on overseas investment for three years; under the CRS, Hong Kong account transaction records are automatically exchanged with the mainland annually, and long-term retained earnings triggerCFC (Controlled Foreign Corporation) Rules, treated as a back-pay dividend20% Individual Income Tax
; Transfer pricing adjustment, resulting in an increase in the profits of the mainland entity, and a back payment of corporate income tax of 25% plus interest.

In November 2025, an Amazon seller in Shenzhen left 3.5 million yuan in proceeds from merchandise sales in an undeclared, undistributed dividend account at HSBC in Hong Kong,The total amount of back taxes and late payment penalties ultimately paid was 5.8 million yuan.

Compliance Practices

The mainland parent company is registered with ODI as holding a controlling interest in a Hong Kong entity; with no substantive net profit in Hong Kong, sales are limited to 2%–3%, and the number of office employees does not exceed 8%; excess funds at year-endCompliance, Dividends, and Tax Payment, and undergo an annual audit in Hong Kong.

 Scenario 5: Purchase Without an Invoice(math.) genusThere are only screenshots of overseas expenses, and the company's profits have been significantly adjusted upward.

Common Errors

Domestic purchases lack 13% special invoices or purchase ledgers; payments transferred from personal accounts to suppliers lack corporate bank transaction records; Amazon advertising and overseas warehouse rent are documented only with screenshots, without complete invoices or payment receipts; Multiple stores share advertising, warehousing, and labor costs without a cost-allocation agreement; salaries and service fees are inflated artificially to artificially increase costs and suppress reported profits.

Regulatory Consequences

2026Completely Eliminate Fixed-Rate Taxation, All expenses without supporting documentation will be added to taxable income, and back taxes will be paid.25% Corporate Income Tax; A tax audit to investigate tax avoidance was launched following the discovery of substantial fictitious cost entries.

The Shenzhen Municipal Bureau of Commerce, in collaboration with Amazon, held a briefing to clarify that audited tax assessment will be fully implemented by 2026; all cross-border enterprises must establish a standardized financial accounting system, and the “alignment of the four flows” is the sole prerequisite for qualifying for export tax incentives.

Compliance Recommendations

Create a list of cost documentation for cross-border e-commerce and identify the respective accounting records for expenses such as procurement, logistics, advertising, platform commissions, overseas warehouses, software subscriptions, and labor.

If multiple stores or entities share advertising, warehousing, employees, and office space, they should also establish reasonable cost-sharing rules and retain cost-sharing agreements, calculation sheets, and settlement documents to avoid having all costs allocated to a single company.
