Is tax based on the price of goods and paid at the time purchased?

Yes, sales tax is typically based on the price of goods and is collected at the time of purchase. When a consumer buys a product, the tax is added to the total price, and the retailer collects it on behalf of the government. The rate of sales tax can vary by location and type of goods. However, other types of taxes, like income tax or property tax, are not based on the price of goods and have different payment structures.
