How Sales Tax Is Calculated
Sales tax is calculated as a percentage of the purchase price. The formula is simple:
Sales Tax Formula
Sales Tax = Purchase Price x (Tax Rate / 100)
Total Cost = Purchase Price + Sales Tax
Example: $100 purchase with 8% tax = $100 x 0.08 = $8 tax. Total = $108.
Common Sales Tax Exemptions
Many states exempt certain items from sales tax. Common exemptions include:
- Groceries: Most states exempt or reduce tax on unprepared food
- Prescription Drugs: Generally tax-exempt in most states
- Clothing: Some states (like Minnesota, Pennsylvania) exempt clothing under certain amounts
- Medical Equipment: Often exempt when prescribed by a doctor
- Manufacturing Equipment: Business equipment often exempt
Online Purchases and Sales Tax
Following the 2018 Supreme Court decision in South Dakota v. Wayfair, states can now require online retailers to collect sales tax even if they don't have a physical presence in the state. This means most online purchases now include sales tax based on your delivery address.
Major marketplaces like Amazon, eBay, and Etsy automatically collect and remit sales tax for most states. When shopping online, the sales tax shown at checkout is based on your shipping address, not the seller's location.
