Sales tax in the US ranges from 0% in Oregon and Delaware to over 10% in parts of Louisiana — and the gap between the lowest and highest combined rates can mean hundreds of dollars on a single large purchase. Louisiana raised its state rate to 5% in 2025, pushing its combined average past Tennessee to become the nation's highest.
