I. Tax-Inclusive vs. Tax-Exclusive
Does the quote include tax or not? According to tax practice, it is important to distinguish the tax components of a custom assembly line quote: for equipment sales, the VAT rate for general taxpayers is 13% (allowing for the issuance of special VAT invoices that the buyer can use for input tax deduction), while the levy rate for small-scale taxpayers is 3% (currently reduced to 1% under prevailing policies);
transportation, installation, and technical services are subject to rates of 9% or 6%. A “tax-inclusive price” refers to the total amount on the invoice (goods plus tax), whereas a “tax-exclusive price” refers to the value of the goods themselves, with the difference representing the VAT. If a contract does not explicitly state whether the price is tax-inclusive, tax regulations and commercial practices generally deem it to be tax-inclusive. Therefore, you should clarify whether the quote includes tax and whether a special VAT invoice or a general invoice will be issued before discussing the price; overlooking this detail could easily wipe out several percentage points of profit.

Conversion Formulas
Conversion formulas and common errors.
In financial practice, there are only four formulas for converting between tax-inclusive and tax-exclusive prices: Tax-inclusive price equals tax-exclusive price multiplied by (1 + tax rate)—e.g., a tax-exclusive price of 1 million with a 13% tax rate results in a tax-inclusive quote of 1.13 million; tax-exclusive price equals tax-inclusive price divided by (1 + tax rate)—e.g., 1.13 million divided by 1.13 equals 1 million; tax amount equals tax-inclusive price minus tax-exclusive price, or tax-inclusive price multiplied by the tax rate and divided by (1 + tax rate); a common error is calculating the tax amount by simply multiplying the tax-inclusive price by 0.13 (e.g., 1.13 × 0.13 = 14.69, whereas the correct tax amount is 13); regarding price quotes covering costs—first, clarify that the net amount received is tax-exclusive revenue, and calculate the tax burden, surcharges, costs, and gross profit separately—as the gap between the tax-inclusive quote and the actual revenue received includes VAT, surcharges, corporate income tax, and individual income tax on dividends.
III.
Special VAT Invoices vs. General VAT Invoices
What is the difference between special and general VAT invoices?
According to tax policy, the invoice type directly affects the price: Special VAT Invoices—issued by general taxpayers at a 13% rate; the purchaser can deduct input VAT, meaning the deductible tax amount represents actual savings; General VAT Invoices—input VAT cannot be deducted, but they suffice for enterprises that do not require deductions (such as the service industry or administrative and public institutions); the tax surcharge added by suppliers—this covers the comprehensive cost, including not only VAT but also corporate income tax, surcharges, and individual income tax on dividends, so do not judge whether a supplier is ripping you off based solely on the VAT rate; the pitfall of declining an invoice—if you decline an invoice, the tax burden will ultimately fall on you—do not forgo an invoice just to save a few percentage points, as the lack of input deduction means bearing the full tax burden.

Contract Drafting
How to draft a contract most securely.
Based on standard contract templates, the price clause for non-standard equipment contracts is typically structured in three lines: the total contract price (tax-inclusive) is RMB __; the VAT rate is 13%; the breakdown includes the pre-tax amount (RMB __), the VAT amount (RMB __), and the total price including tax (RMB __). Price composition: equipment manufacturing costs account for __%, design fees for __%, and other expenses for __%. Benefits of itemized pricing: it avoids disputes, and stamp duty is calculated based on the pre-tax amount (if the contract specifies the pre-tax amount, stamp duty is calculated on that basis). Tax rate adjustment clause: the adjusted price equals (price at signing ÷ (1 + tax rate at signing)) × (1 + adjusted tax rate). Separate contracting: signing separate contracts for sales, transportation, installation, and technical services can reduce the tax burden; otherwise, VAT is levied based on the primary business activity—the tax-inclusive price and the tax rate must always appear together in the contract.

Key Points to Avoid Pitfalls
Key points for the purchaser to avoid pitfalls.
Based on industry experience, there are five things to consider regarding tax when purchasing non-standard assembly lines: check the tax status on the quotation—clarify whether the price is tax-inclusive or exclusive before comparing prices; use a unified basis for price comparison—do not directly compare a tax-inclusive price from Supplier A with a tax-exclusive price from Supplier B; convert all figures to the total tax-inclusive price; calculate the true cost by factoring in VAT special invoice deductions—deductible tax amounts effectively represent a price reduction; look beyond just VAT—surcharges added by suppliers for invoicing reflect the comprehensive tax burden (including VAT, corporate income tax, surcharges, and individual income tax on dividends); issue invoices only after acceptance—issue VAT special invoices after successful acceptance and align payment terms with the latest tax rate changes; ensure the “four flows” match—the contract, invoice, funds, and goods must correspond consistently; ensure performance figures are genuine—clearly specify whether prices are tax-inclusive or exclusive to ensure quotations are free of “padding.”
Conclusion
Does the quote for a custom-built assembly line include tax? The conclusion is: “If the contract doesn’t specify, it is usually deemed tax-inclusive; stating it clearly prevents disputes.” Key points include: Tax rates—13% for equipment sales by general taxpayers, 3% for small-scale taxpayers (reducible to 1%), 9% for transport and installation, and 6% for technical services; Conversions—tax-inclusive price equals the pre-tax price multiplied by 1.13, pre-tax price equals the tax-inclusive price divided by 1.13, and the tax amount equals the tax-inclusive price multiplied by the tax rate and divided by (1 + tax rate); Special vs. General VAT Invoices—special invoices allow for input tax deduction while general invoices do not, and supplier markups cover the comprehensive costs of VAT, corporate income tax, surcharges, and individual income tax on dividends; Contracts—specify the total price (tax-inclusive), list the pre-tax amount and tax amount on separate lines, and include a formula for tax rate adjustments;
Pitfalls to avoid—use a unified basis for price comparisons, factor in the true cost after special invoice deductions, issue invoices only after passing acceptance checks, and ensure the “four flows” (goods, funds, invoices, and contracts) align.
Industry practice dictates that for custom assembly line orders worth hundreds of thousands or millions, a single incorrect word regarding tax inclusion can result in a price difference of tens of thousands—so the very first line of the quote should clearly state: “Includes 13% special VAT invoice.”
