Use an address-level rate for the final check
The state comparison rate is useful for a first estimate, but city, county, transit, and special-district rates can change the total. Product rules matter too: groceries, medicine, clothing, services, motor vehicles, and temporary sales-tax holidays may receive different treatment. Confirm the purchase address and product category with the state tax agency before relying on a material estimate.
How to improve this estimate
Look up the combined rate for the destination where the item is delivered, then replace the local average. Check whether the item is taxable and whether a special rate applies. Keep the pre-tax price separate from shipping, fees, trade-ins, and rebates because each state can treat those amounts differently.
