How Does Sales Tax Work?
Sales tax is a percentage added at the point of sale, set by your state, county, and city — not the federal government. Rates range from 0% in Oregon, Montana, Delaware, and New Hampshire to over 10% when state and local rates combine in parts of Louisiana, Tennessee, and Arkansas. Unlike income tax, there are no brackets. Every taxable dollar is taxed at the same rate.
Not everything is taxed equally. Most states exempt groceries, prescription drugs, and clothing (or tax them at a reduced rate). Some items like prepared food or alcohol carry higher rates. A single "sales tax rate" doesn't always tell the whole story — what you're buying matters as much as where you're buying it.
Shop44 handles all of this for you — download free on the App Store or Google Play.
