A WFOE that exports goods from China can recover the VAT incurred on its China purchases. The VAT refund system — the export VAT refund, or chūkǒu tuìshuì — returns the input VAT that the company paid to its Chinese suppliers, so that the exported goods leave China free of Chinese VAT. The refund is a significant cash flow item for an export-oriented WFOE — the refund can be 13% of the purchase cost for standard-rate goods — and the speed and reliability of the refund process directly affect the company’s working capital.
But the VAT refund system is procedurally demanding. The refund claim must be supported by a complete set of export documentation, the purchase invoices must be verified against the tax bureau’s database, and any discrepancy — a missing customs declaration, an unmatched invoice, a late filing — delays the refund or results in its denial. Here’s how the system works and how to manage it.
The VAT Refund Concept
The VAT on goods exported from China is zero-rated — the export sale is subject to VAT at a rate of 0%. Because the export is zero-rated, the exporter does not charge VAT to its overseas customer — the export invoice shows a VAT rate of 0% and includes no VAT amount. The exporter recovers the input VAT that it paid to its Chinese suppliers for the raw materials, components, and services that went into the exported goods.
The zero-rating is an international norm — goods are taxed in the country of consumption, not in the country of production — and the Chinese VAT system is consistent with international practice. The export VAT refund is not a government subsidy — it’s the mechanism for implementing the zero-rating.
The refund rate is the rate at which the input VAT is refunded. The refund rate is not always the same as the input VAT rate. A product that’s subject to 13% input VAT for raw materials may have a refund rate of 13%, 10%, 9%, or less depending on the product classification. The refund rate is set by the government and is published in the export VAT refund rate schedule, which is updated periodically. The company must determine the refund rate for its specific export product and calculate the refund on that rate.
A product with a refund rate lower than the input VAT rate — for example, 13% input VAT at a 10% refund rate — results in input VAT that’s not refunded. The unrefunded input VAT becomes a cost to the business. The cost is the difference between the input VAT rate and the refund rate, multiplied by the purchase cost. A product with a 13% input VAT rate and a 10% refund rate has a 3% VAT cost that the company bears as an operating cost.
The Refund Methodologies
There are two methodologies for calculating the export VAT refund: the exemption-credit-refund method and the exemption-refund method. The exemption-credit-refund method is for general taxpayers — companies that are registered as general taxpayers for VAT. The exemption-refund method is for small-scale taxpayers and for certain categories of enterprises.
Under the exemption-credit-refund method, the company first calculates the input VAT that’s not creditable — the input VAT multiplied by the difference between the export tax rate and the refund rate. This non-creditable input VAT is charged to the cost of goods sold. The company then calculates the creditable input VAT — the input VAT minus the non-creditable portion. The creditable input VAT is compared with the output VAT on the company’s domestic sales, and the net VAT position determines whether the company has a VAT payable or a VAT refundable for the period.
The method effectively divides the input VAT into two components — the refundable portion at the refund rate and the non-refundable portion at the rate differential — and applies the refundable portion against the output VAT on domestic sales. If the refundable input VAT exceeds the output VAT on domestic sales, the excess is refundable in cash. If the refundable input VAT is less than the output VAT, the company pays the net VAT to the tax bureau.
Under the exemption-refund method, the company simply multiplies the export sales revenue by the refund rate to calculate the refund amount. The method is simpler — no input-output VAT comparison, no allocation between domestic and export sales — but it’s only available to a limited category of enterprises, primarily small-scale taxpayers.
The Documentation Requirements
The export VAT refund claim requires a complete set of export documentation for each export shipment. The core documents are the export customs declaration — the form that shows the goods were exported from China — the export sales invoice, the purchase invoices from the Chinese suppliers, and the verification of the purchase invoices against the tax bureau’s database.
The export customs declaration is the primary evidence of export. The declaration must match the export sales invoice in quantity, value, and product description. A discrepancy between the declaration and the invoice — a different product code, a different quantity, a different value — results in the refund claim being rejected for that shipment.
The purchase invoices must be special VAT invoices — the VAT invoices that carry an input VAT credit — and must be verified against the tax bureau’s invoice verification system. The verification confirms that the supplier reported the sale and the output VAT, and that the invoice is genuine. A supplier who issued the invoice but didn’t report the output VAT creates a verification failure that blocks the refund claim.
The verification process is electronic — the company submits the invoice information to the tax bureau’s system, and the system matches it against the supplier’s output VAT reporting. The verification must be completed before the refund claim is filed. A company that files the refund claim before completing the verification may have the claim rejected or may have the refund delayed until the verification is completed.
The Claim Filing Process
The refund claim is filed monthly — or quarterly for small-scale taxpayers — together with the VAT return. The company reports the export sales for the period, calculates the refundable amount using the applicable method, and submits the supporting documentation — the export declarations, the export invoices, the purchase invoices — with the claim.
The tax bureau reviews the claim and may request additional documentation. A claim that’s complete and correct is processed within the processing time — a specified number of working days that varies by region and by the company’s compliance history. A company with a clean compliance history and electronic filing may receive the refund within five to ten working days. A company with a problematic compliance history or paper filing may wait longer.
The refund is paid to the company’s bank account. The refund is not a tax credit — it’s cash — and it’s deposited directly into the company’s account. The cash impact of the refund is significant. A company that exports 10 million RMB of goods per month with a 10% refund rate receives 1 million RMB per month in VAT refunds — 12 million RMB per year — which constitutes a material component of the company’s working capital.
A delayed refund — because the claim is incomplete, because the documentation doesn’t match, because the tax bureau is conducting an audit — is a working capital problem. The company has paid the input VAT to its suppliers but hasn’t recovered it from the tax bureau. The working capital gap can be financed — the bank can lend against the refund claim — but the financing cost reduces the economic benefit of the refund.
Common Problems and How to Avoid Them
The most common problem is incomplete or inaccurate export documentation. The export customs declaration, the export sales invoice, and the purchase invoices must all match. A company that uses a freight forwarder to prepare the customs declaration and doesn’t review the declaration before it’s filed may discover a discrepancy after the goods have sailed — and a post-sailing correction to a customs declaration is difficult and time-consuming.
The solution is document control. The company should prepare the export documentation in-house — the commercial invoice, the packing list — and provide it to the freight forwarder with clear instructions. The freight forwarder should provide a draft of the customs declaration before filing it, and the company should review the draft against its own documentation. The review should be systematic — a checklist of the data elements that must match across the documents — and should be performed by a person who understands the refund requirements.
The second common problem is late verification of purchase invoices. The company must verify the purchase invoices before filing the refund claim, and the verification can take several days — the supplier must report the output VAT, and the tax bureau’s system must process the matching. A company that files the refund claim on the last day of the filing period and discovers that not all of the purchase invoices have been verified is too late — the claim must be filed without the unverified invoices, and those invoices must be carried forward to the next period.
The solution is early verification. The company should verify the purchase invoices as soon as they’re received from the supplier — not wait until the refund claim filing date — and resolve any verification issues immediately. An invoice that fails verification because the supplier hasn’t reported the output VAT should be escalated to the supplier for immediate correction.
The third common problem is non-compliance with the record-keeping requirements. The company must retain the export documentation — the customs declarations, the export invoices, the purchase invoices, the bank records — for the statutory retention period, generally ten years. A company that loses the documentation — because the freight forwarder didn’t keep it, because the accounting system crashed, because the files were not backed up — cannot support the refund claim in a subsequent audit and may be required to repay the refund plus interest and penalties.
The Bonded Processing Alternative
A company that processes imported materials into finished goods for export can use bonded processing — processing trade, or jiāgōng màoyì — instead of the standard import-export VAT refund process. Under bonded processing, the imported materials enter China duty-free and VAT-free — the company doesn’t pay import VAT on the materials — and the finished goods are exported without a VAT refund claim because no VAT was paid on the inputs.
The bonded processing system simplifies the VAT management for a processing-for-export WFOE. The company doesn’t pay input VAT at import and doesn’t claim a refund at export — the VAT simply doesn’t arise. The bonded processing requires separate customs registration, separate bonded warehouse management, and separate customs reporting — the company must account for the imported materials from import to export — and the administrative burden is higher than the standard import-export process. The choice between bonded processing and the standard VAT refund process depends on the company’s scale, its product, and its ability to manage the bonded processing compliance.
