US Tipping Etiquette & Sales Tax Rules
Tipping on Pre-Tax vs Post-Tax
Traditional American etiquette experts (like the Emily Post Institute) recommend calculating tip on the pre-tax subtotal. You are tipping the server for their service, not paying a percentage on state taxes.
Combined State vs Local Sales Tax
While states set base rates (e.g. California 7.25%), municipalities add local city and county taxes, pushing combined rates to 9.5% or 10.25% in cities like Los Angeles and Chicago.
Standard Gratuity Benchmarks
In US sit-down restaurants, 15% to 18% is standard for adequate service, 20% is customary for good service, and 22% - 25% is awarded for outstanding hospitality.
