Tax Amount = Purchase Price × Tax Rate / 100. Total Price = Purchase Price + Tax Amount. Example: A laptop priced at $800 in a state with 8.5% sales tax: Tax = $800 × 8.5/100 = $68. Total = $800 + $68 = $868. To find the pre-tax price from a total: Pre-tax Price = Total Price / (1 + Tax Rate/100).
US sales tax rates vary significantly by state. States like Oregon, Montana, New Hampshire, Delaware, and Alaska have no sales tax. States like California (up to 10.25% with local taxes), Tennessee (9.55%), Arkansas (9.51%), and Louisiana (9.55%) have the highest combined rates. Many states exempt groceries and prescription medications from sales tax.
Sales Tax (US): Collected only at the final point of sale to the consumer. VAT (Europe, UK): Collected at each stage of production; businesses claim back VAT on inputs. GST (India, Australia, Canada): Similar to VAT — a comprehensive consumption tax replacing multiple taxes. The end price for consumers is similar, but the collection mechanism differs significantly.
Since the 2018 US Supreme Court ruling (South Dakota v. Wayfair), online retailers must collect sales tax in states where they have "economic nexus" — typically over $100,000 in sales or 200+ transactions. This means most major online purchases now include applicable state sales tax, unlike the early days of e-commerce when online shopping offered a tax advantage over physical stores.
Sales tax is a consumption tax imposed by the government on the sale of goods and services, calculated as a percentage of the purchase price.
Sales Tax = Purchase Price × Tax Rate / 100. For example, a $100 item with 8% tax costs $100 + $8 = $108 total.
Not exactly. GST (Goods and Services Tax) is a comprehensive tax used in India, Australia, and Canada. Sales tax in the US varies by state and is charged only at the point of sale.
In some countries, businesses registered for GST/VAT can claim back the tax paid on business purchases. Individual consumers generally cannot claim it back.
