1. Errors in revenue accounting criteria (most widespread)

The Nature of the Problem: The tax base for value-added tax isThe buyer pays the full amount(including the product price and shipping costs borne by the buyer); platform commissions, advertising fees, and other deductions are considered operating expenses and may be used to offset corporate income tax,May not be deducted from the taxable income for Value-Added Tax purposesThe

typical example::

The buyer pays $100; the platform deducts $20; the company actually receives $80—Value-Added Tax should be calculated based on$100Report the full amount; the $20 that was withheld will be recorded as a cost deduction,Under no circumstances should you report the VAT revenue as $80.The


2. Confusion in Accounting Due to Customs Declaration Methods

9810 Overseas Warehouse Model: Export customs clearance for goods is merely a cross-border transfer of inventory,Revenue is recognized only upon completion of the end-user sale.The

There is an inherent time lag between the volume of shipments declared for customs clearance in a given period and the sales revenue for that period.

It is essential to establish a comprehensiveOverseas Warehouse Inventory Ledger(Complete records of shipments, sales, scrapped items, and inventory); otherwise, any discrepancies in the data cannot be explained during an audit.

1039 Market Procurement Model: Frequently Asked Questions includeSubject-Verb Displacement—A sole proprietor has completed Form 1039 for customs declaration and payment of duties, but the entity actually operating the store is a limited liability company.

Tax Payment History for Self-Employed IndividualsLimited liability companies cannot be exempt from their income reporting obligations...A comparison of the two sets of primary data will directly raise tax-related concerns.

The tax-exemption policy for the Comprehensive Pilot Zone, which does not require invoices, only exempts Value-Added Tax,If there are actual sales, you must file a VAT exemption return as required....and it is by no means a zero return.


3. Mismatch between customs declaration data and cargo flow

  • buy orders to sell goods (e.g. for export): The store has a large volume of sales data, but the business entity has no corresponding customs declaration records, resulting in a disconnect between logistics and sales data,Will Definitely Be Flagged for Tax Irregularities. The safest approach is toThe entity operating the store must be the same as the entity filing the customs declaration.; If the transaction is split (e.g., Company A handles sales and Company B handles customs clearance), a formal cooperation agreement and complete business documentation must be retained to verify the authenticity of the trade.
  • Follow-up Oversight of Advance Tax Refunds (9810): For goods in overseas warehouses that are scrapped, lost, or returned, accounting adjustments must be made promptly, and the corresponding tax refunds must be repaid.Reaping the benefits of tax refunds without writing off inventory losses...is currently a high-risk area that is particularly prone to audits.

4. Compliance Thresholds for Fund Transactions

  • Trade ReceivablesLarge sums of money must not be transferred to the private accounts of corporate shareholders over an extended period of time.. Corporate foreign currency accounts, third-party payment services such as Wanlihui, and offshore accountsInclude all of them in the data comparison. Businesses that are large in scale but have virtually no payments flowing into their corporate accounts, with all funds routed through smuggling cards, are considered priority targets for audits.
  • Funds held on third-party platforms are a normal part of business operations, but“Money remaining on the platform and not withdrawn” cannot be used as a catch-all explanation., you must regularly save screenshots of your account and maintain a fund ledger.
  • Receiving Payments into Overseas Accounts: Without proper ODI filing, it will be difficult to provide a reasonable explanation for retained overseas profits. Once the routine exchange of CRS data begins, remittances from overseas accounts will be directly reported to the domestic tax authorities, and there is a high probability that these funds will be deemed domestic business income, resulting in the need to pay back taxes.

5,Non-compliant operations in the store cluster model and deficiencies in document management

Splitting companies into multiple entities to operate a network of stores in order to take advantage of tax incentives for small and micro enterprises, even though they share the same warehouses, staff, suppliers, and ERP systems,Under the "Golden Tax Phase IV" penetrative audit, such cases will be deemed to constitute a single business entity, and the revenue from all stores will be consolidated for unified tax calculation.The

If goods are transferred or inventory is moved between stores without a contract or accounting records, such transactions will be treated as sales during an audit and will result in a tax liability.

The statutory retention period for documents is 10 years.

Historical data in the platform's backend will expire and become invalid; it must beExport a local backup manually each monthThe

The required records to be retained include:

Customs declarations, bills of lading, itemized freight forwarding invoices, platform settlement reports, refund records, etc.


6,Compliance Approach and Recommendations

Step 1: Conduct a Comprehensive Self-Assessment

Take 1–2 weeks to review the past 1–2 yearsPlatform Sales, Customs Declaration, Foreign Exchange Receipts, Bookkeeping and Tax FilingReconcile all four sets of data and create a discrepancy ledger—compare sales figures, customs declaration amounts, payment receipts, and reported revenue on a period-by-period basis to determine the size of the discrepancy, where it occurred, and what supporting documentation is available.

In practice, the tax authoritiesRecognitionThere are only four types of differences:

  1. 9810 Stocking Lead Time;
  2. Cross-quarter refunds and chargebacks;
  3. Funds are held on a third-party platform and have not been withdrawn;
  4. Retention of Overseas Profits Following Compliance with ODI Filing Requirements.

Due to errors in bookkeeping, failure to file Form 1039 through the company, and other reasons, during an audit...Largely disagreeThe

Step 2: Standardize Current Operations

Shipping inventory from FBA overseas fulfillment centers9810, Small packages shipped directly9610B2B exports go9710, to prevent misalignment of the subject.

All supporting documents, such as platform fee deductions and overseas warehouse invoices, are kept in their entirety to ensure thatDocumentation is availableThe

Step 3: Proactively Correct Previous Filings

The tax authority opened a case and issued a verification noticebeforehandIf a taxpayer voluntarily corrects a tax return and pays the back taxes and late payment penalties, the following may apply:Fault-Tolerance Policy; Once you receive an official notice of an audit, there is essentially no room for corrective action.


💡 Core principles: Compliance isn't about forcing four sets of data to be exactly the same—that's unrealistic. True compliance isDocumented discrepancies, justified variances, and full traceability. Keeping detailed records, properly filing documents, and ensuring business processes run smoothly are currently the most reliable risk control measures.
