Pre-Tax vs Post-Tax Tip Calculator
Compare pre-tax vs post-tax tipping side by side. See the exact dollar gap and why most etiquette experts recommend tipping on the subtotal.
Statutory Gratuity Rule: Under FLSA 29 U.S.C. § 203(m) and 29 CFR Part 531, tips are the absolute property of employees; employers and managers are strictly barred from retaining any portion of tip pools. Standard U.S. dining gratuity benchmarks range from 15% (standard service) to 18%–20% (good service) and 22%+ (exceptional service), calculated directly on the pre-tax subtotal.

Breakdown details
Standard practice is to tip on the pre-tax amount. However, some diners tip on the post-tax total (the full amount shown on the check). This shows you the difference between the two approaches.

What it does
Shows both methods at once and highlights the dollar difference. Example: a $100 pre-tax bill at 8% tax. Pre-tax 20% = $20.00; post-tax 20% = $21.60—a $1.60 gap that grows with the bill. We recommend pre-tax because the tax isn't the server's income.

Frequently asked questions
What is the difference between tipping before and after tax?
Post-tax tipping adds a few dollars that go partly to the government via tax. On $100 pre-tax at 8%, 20% post-tax is $21.60 vs $20.00 pre-tax.
Why tip pre-tax?
The sales tax is paid to the government, not your server. Tipping on the subtotal keeps your gratuity entirely with the person who served you.
