Auto-Gratuity Explained: Do You Tip on Top of a Service Charge?
June 7, 2026 · 6 min read
You finish a great group dinner, glance at the check, and see a line that already added 18% before you reached for your card. That is automatic gratuity — and the panic question it triggers is always the same: do I tip again on top of this? The short answer is no. But the words on the check matter, because not every added charge means the same thing.
Three Things That Look Alike on a Check
| Line Item | What It Means |
|---|---|
| Automatic gratuity | A mandatory tip (often 18–20%) that goes to the server |
| Service charge | A fee that belongs to the restaurant — may not reach staff |
| Suggested gratuity | Printed examples (15/18/20%) you can ignore or follow |
| Voluntary tip | The blank tip line you fill in yourself |
Why Large Parties Get Auto-Gratuity
A table of ten ties up a server for the whole evening and often a second helper, yet large groups historically tipped less reliably per head — one person assuming another covered it, and the math splitting awkwardly. Restaurants add an automatic 18–20% gratuity (commonly for parties of six or more, stated on the menu) so the server is fairly paid for an entire night's work on one table.
Do You Add More?
When the line says gratuity, that is your tip — you owe nothing extra. If service was genuinely outstanding, adding a few dollars on the open line is a kind bonus, not an obligation. If service was poor, you generally cannot remove a properly disclosed auto-gratuity, but you can and should speak to a manager.
The Service Charge Trap
Here is the catch: a service chargeis legally different from a gratuity. Under federal rules, a mandatory service charge belongs to the business, which decides whether to pass it to staff. So a 20% "service charge" might fund wages, the house, or both. If you want to be sure your server is taken care of, ask: "Does the service charge go to the staff?" If the answer is no or unclear, leave a separate tip.
Watch the Pre-Filled Tip Line
A common surprise: the check shows auto-gratuity already added and a blank tip line below it. Some diners fill in another 20% without noticing, tipping nearly 40% by accident. Always read from the subtotal down before you sign. If gratuity is already there, the tip line should stay blank unless you are deliberately adding extra.
The Takeaway
Read the words, not just the numbers. "Gratuity" means the tip is handled. "Service charge" means ask where it goes. And always scan for a second blank tip line so a great dinner doesn't cost you a double tip. To learn how restaurants divide tips behind the scenes, read our tip pooling guide.
