How to calculate export tax rebates for prefabricated building components (2026 standards): ① Foreign trade enterprises—Refundable VAT amount = Tax base for refund/exemption × Export tax rebate rate; ② Manufacturing enterprises—Current period exemption, credit, and refund amount = FOB export price × Foreign exchange conversion rate × Tax rebate rate − Deductions; ③ Key points—Look up the tax rebate rate in the official database; determine the tax base (purchase cost/FOB price); account for deductions for tax-exempt purchased materials. In short: How to calculate the rebate—Foreign trade enterprises = Tax base × Tax rebate rate;
Manufacturing enterprises = FOB price × Conversion rate × Tax rebate rate − Deductions; look up the rate in the database and retain invoices/customs declarations.
I. Calculation of Tax Exemption and Refund for Foreign Trade Enterprises (2026 Standards)
Calculation of export tax refunds for foreign trade enterprises (based on announcements by the State Taxation Administration and the Ministry of Finance):
- Refundable Tax Amount: VAT refundable amount = Tax base for tax refund/exemption × Export tax refund rate (Basic formula);
- Tax Base: Based on the amount stated in the special VAT invoices for the purchase of exported goods (weighted average purchase price × quantity) (Purchase basis);
- Refund Rate: Look up the refund rate corresponding to the HS code in the tax refund rate database (usually ≤ the levy rate of 13%) (Refund rate);
- Commissioned Processing: For goods subject to commissioned processing, repair, or maintenance, the calculation is based on the tax base for commissioned processing × export tax refund rate (Commissioned processing);
- Key Point: Export tax refund = Purchase cost × Export tax refund rate; declared based on special VAT invoices/customs declarations (Declaration based on vouchers).
II.
Calculation of Tax Exemption, Credit, and Refund for Manufacturing Enterprises (2026 Standards)
Calculation of export tax refunds for manufacturing enterprises (based on announcements by the State Taxation Administration and the Ministry of Finance):
- Current Period Exemption, Credit, and Refund Amount: = Current period export FOB price × RMB exchange rate × Export tax refund rate − Reduction amount for exemption, credit, and refund (Formula);
- Reduction Amount: = Price of tax-exempt purchased raw materials × Export tax refund rate (Reduction amount);
- Non-exemptible and Non-creditable Amount: Non-exemptible and non-creditable tax amount = FOB price × Exchange rate × (Levy rate − Refund rate); transferred to cost (Transfer to cost);
- Refundable Tax Amount: If the carry-forward input VAT at the end of the period ≤ the exemption, credit, and refund amount, the full amount is refunded; otherwise, the carry-forward amount is refunded, and the difference is handled via exemption and credit (Exemption, credit, and refund);
- Key Point: Manufacturing enterprises follow the “exemption, credit, and refund” method: first exempt, then credit, and finally refund (Exemption, credit, and refund).
III. Implementation of Export Tax Rebates for Overseas B2B Transactions (2026 Standards)
The process for obtaining export tax rebates for prefabricated construction components in overseas B2B transactions is implemented as follows (based on export practices, industry conventions, and case studies):
- Prepare documentation: Export customs declaration (rebate copy), special VAT invoice, proof of foreign exchange receipt/verification, contract/packing list;
- Verify tax rates: Consult the tax rebate rate database (matching HS codes to rates) and confirm the difference between the levy rate and the rebate rate;
- Calculate rebate amount: For trading enterprises = Taxable basis × Rebate rate; For manufacturing enterprises = FOB price × Exchange rate conversion factor × Rebate rate − Deductions;
- File declaration: Submit via the Electronic Tax Bureau and retain supporting documents (customs declaration, invoices, foreign exchange records);
- Risk warnings: Rejection due to document discrepancies, audits for under-reporting cargo value, and losses from late filing—ensure complete documentation, correct tax rates, and timely filing.
Conclusion
How is the export tax rebate for prefabricated construction components calculated?
In short: For trading enterprises = Taxable basis for rebate/exemption × Export tax rebate rate (based on purchase invoice amount); For manufacturing enterprises = Current period export FOB price × Foreign exchange conversion factor × Rebate rate − Deductions (under the “Exemption, Credit, and Refund” method); Key points = Check rebate rate database, determine taxable basis (purchase price/FOB price), account for deductions on tax-exempt material purchases, and transfer non-exempt/non-creditable amounts to cost; File using customs declaration + special VAT invoice + proof of foreign exchange receipt.
Overseas B2B procurement strategy: Prepare documents (customs declaration/special VAT invoice/foreign exchange record/contract), verify tax rates (rebate rate database/levy-rebate difference), calculate rebate amount (trading/manufacturing formulas), file declaration (Electronic Tax Bureau/document retention), and mitigate risks (complete documents/correct rates/timely filing)—this allows for an accurate calculation of the tax rebate.
