Why Your Receipt Total Looks Higher Than Expected
In most US states, prices are shown before tax. That gap between the shelf price and your receipt total is sales tax—here's how to calculate it.
Prices Don't Include Tax (In Most US States)
In the US, retail prices are almost always displayed before sales tax. The tax is calculated and added at checkout. So the gap between the shelf price and your receipt total isn't an error—it's sales tax.
How Tax Gets Added
When the cashier rings you up, the register multiplies each taxable item by the combined sales tax rate for that store's location. Non-taxable items (groceries in most states, prescription drugs, etc.) don't get tax added.
Why Your Total Can Be Hard to Predict
Combined rates vary by city. A Target in downtown Los Angeles charges 10.25% combined; one in a suburb a few miles away might charge 9.5%. If you're mentally adding up items and the total doesn't match, it's likely a rate difference—or some items had different taxability.
How to Check the Tax on Your Receipt
Most receipts list the tax rate used and the total tax charged. If you want to verify: take the pre-tax subtotal, multiply by the rate shown on the receipt, and you should get the tax amount shown.
