What is Sales Tax?
Sales tax is a consumption tax imposed by the government on the sale of goods and services. The tax is usually calculated by applying a percentage rate to the taxable price of a sale. Sales tax is collected by the retailer, who then passes it on to the government.
Sales Tax Formula
The formula to calculate sales tax is straightforward:
$$\text{销售税额} = \text{税前价格} \times \text{销售税率}$$
$$\text{税后价格} = \text{税前价格} + \text{销售税额}$$
Where the tax rate is expressed as a percentage (e.g., 6.5% would be 0.065 for calculations).
