What is Sales Tax?
Sales tax is a consumption tax levied by a government on the sale of goods and services. The tax is usually added to the sale price of products or services at the point of purchase and is collected by the retailer on behalf of the government.
Sales tax rates vary by country, state, province, or even city. Here’s a quick overview of how it’s applied in different regions:
- United States: Sales tax is imposed at the state and local level. Some states like Oregon have 0% sales tax, while others like California have rates exceeding 7.25%, not including additional local taxes.
- Canada: The system includes GST (Goods and Services Tax), PST (Provincial Sales Tax), and HST (Harmonized Sales Tax). Each province has its own rules and rates.
- United Kingdom: The UK uses VAT (Value Added Tax), currently set at 20% for most goods and services.
How to Calculate Sales Tax
Depending on where you are, the method of calculating sales tax can be:
- Tax Exclusive: The sales tax is added on top of the product price.
- Tax Inclusive: The sales tax is included in the total price you see.
Let’s walk through both:
Tax Exclusive Calculation (U.S. Style)
Example:
- Price of product: $100
- Tax Rate: 7%
- Calculation:
Sales Tax = $100 × 0.07 = $7Total Price = $100 + $7 = $107
Tax Inclusive Calculation (UK/Canada Style)
Example:
- Total price (with tax): $107
- Tax Rate: 7%
- Calculation:
Price Before Tax = $107 ÷ (1 + 0.07) ≈ $100Sales Tax = $107 - $100 = $7
Sales Tax Formulas
Use the following formulas depending on whether you’re dealing with tax-inclusive or tax-exclusive prices:
Tax Exclusive Formula:

Tax Inclusive Formula:
