税收是国家实现再分配的重要手段，而企业税收也是企业经营过程中的关键环节，如比较常见的消费税、营业税、企业所得税、增值税等，但这些税收是怎么进行计算的?
I. Value-added Tax
一、增值税
1. General taxpayers
1. 一般纳税人
Tax payable = Output tax - Input tax
应纳税额=销项税额—进项税
Output Tax = Sales x Tax rate The tax rate here is 17%
销项税额=销售额×税率此处税率为17%
Component assessable price = cost x (1 cost margin)
组成计税价格=成本×(1 成本利润率)
Component assessable price = cost ×(1 cost margin)÷(1 - consumption tax rate)
组成计税价格=成本×(1 成本利润率)÷(1—消费税税率)
Input tax of prohibited deducters = total input tax of the month ×(total of sales of tax-free items and turnover of non-taxable items in the month ÷ total Sales and turnover of the month)
禁止抵扣人进项税额=当月全部的进项税额×(当月免税项目销售额，非应税项目营业额的合计÷当月全部销售，营业额合计)
2. Imported goods
2.进口货物
Tax payable = component assessable price x tax rate
应纳税额=组成计税价格×税率
Component assessable Price = Customs value Customs duty ( consumption tax)
组成计税价格=关税完税价格 关税( 消费税)
3. Small-scale taxpayers
3.小规模纳税人
Tax payable = sales x levy rate
应纳税额=销售额×征收率
Sales = tax sales ÷(1 levy rate)
销售额=含税销售额÷(1 征收率)
Ii. Consumption Tax
二、消费税
1. General situation:
1.一般情况：
Tax payable = sales amount x tax rate
应纳税额=销售额×税率
Sales excluding tax = sales including tax ÷(1 VAT rate or levy)

Component assessable price =(cost profit)÷(1 - consumption tax rate)
组成计税价格=(成本 利润)÷(1—消费税率)
Component assessable price = cost ×(1 cost margin)÷(1 - consumption tax rate)
组成计税价格=成本×(1 成本利润率)÷(1—消费税税率)
Component assessable price =(material cost processing fee)÷(1 - Consumption tax rate)
组成计税价格=(材料成本 加工费)÷(1—消费税税率)
Composition assessable price =(customs value customs duty)÷(1 - Consumption tax rate)
组成计税价格=(关税完税价格 关税)÷(1—消费税税率)
2. Levy by quantity

应纳税额=销售数量×单位税额
Iii. Customs Duties

Tax payable = taxable income x tax rate
应纳税额=应纳税所得额×税率
Monthly advance payment = monthly taxable income ×25%
