What sales tax adds at the register
At the average combined rate of 9.03%:
| Price | Sales tax | Total |
|---|---|---|
| $25 | $2.26 | $27.26 |
| $100 | $9.03 | $109.03 |

California vs. the national average and its neighbors
The average combined state-and-local sales tax across the 50 states is about 6.66%. California's 9.03% is 2.37 points above that — on a $30,000 car, about $711 more than the national average buyer pays. Combined with a graduated income tax topping out at 13.3%, that shapes how California funds itself — see the California paycheck calculator for the payroll side.
Border shopping is real: here's what the same purchases cost across state lines, at each state's average combined rate.
| State | Combined rate | Tax on $250 | Tax on $30,000 |
|---|---|---|---|
| California | 9.03% | $22.58 | $2,709 |
| Oregon | 0% | $0.00 | $0 |
| Nevada | 8.24% | $20.60 | $2,472 |
| Arizona | 8.54% | $21.35 | $2,562 |
Vehicle purchases are usually taxed by the state where the car is registered, not where it's bought — so the car column shows the rate you'd owe as a resident, not a border-shopping opportunity.
Reading a California receipt
A California receipt typically shows tax as a single line at the combined rate, even though the money is split between the state and one or more local jurisdictions. To check a receipt: multiply the taxable subtotal by 0.0903 (the 9.03% average) — if the tax line is meaningfully higher, you're in a locality above the average, up to 12.5%; if lower, some items were exempt (groceries and prescriptions are exempt or reduced in most states). The reverse mode on the calculator above recovers the pre-tax price from any total.
