What Is Automatic Gratuity?

An automatic gratuity (sometimes called an "auto-grat" or "service charge") is a fixed percentage — typically 18% to 20% — that a restaurant adds to your bill automatically, without you needing to calculate or write it in. It's functionally identical to a tip: the money goes to the server, bartender, and support staff. The only difference is that the restaurant sets the amount instead of you.

Restaurants use automatic gratuity for situations where calculating and splitting a tip among a large group would be awkward, slow, or confusing. Instead of six people arguing over whether to tip 18% or 20%, the restaurant does the math for you and adds it directly to the check. It streamlines the payment process and ensures the staff gets compensated fairly for serving a large party.

The IRS classifies automatic gratuity as a "service charge," which is technically different from a discretionary tip for tax purposes. But from the customer's perspective, it works the same way: you pay it, and the staff receives it.

When Do Restaurants Add Automatic Gratuity?

Restaurants typically add automatic gratuity in these situations:

• Large groups (6+ people): The most common scenario. Serving a table of 8 requires more work than serving two tables of 4, and the restaurant wants to ensure the server is compensated for the extra effort.
• Private dining events: If you've reserved a private room or booked a restaurant for a special event (birthday, anniversary, corporate dinner), expect 18-20% gratuity to be added automatically.
• Holidays: Valentine's Day, Mother's Day, New Year's Eve, and Thanksgiving are peak days for restaurants. Many add automatic gratuity to all tables on these dates, regardless of party size.
• Banquet halls and catering: If you're hosting an event at a banquet hall or ordering catering for a large group, gratuity is almost always included in the contract.
• Some restaurants, all tables: A few restaurants (especially in tourist areas or high-end establishments) add gratuity to every bill, regardless of party size. This is less common but worth checking for.

The restaurant should disclose the automatic gratuity before you order — either on the menu, on the reservation confirmation, or when you're seated. If you're unsure, ask your server before ordering. You have the right to know what you're paying for.

How Much Is Automatic Gratuity?

The most common automatic gratuity percentages are 18% and 20%. Here's what to expect:

• 15%: Rare, but some casual restaurants or banquet halls use this for medium-sized groups (4-6 people).
• 18%: The standard for groups of 6-10 people at most restaurants. This is the most common auto-gratuity rate.
• 20%: Common for groups of 10+ people, private dining events, holidays, and high-end restaurants.
• 22%+: Uncommon, but some upscale venues or banquet halls add 22% for very large events or corporate groups.

If your bill shows an automatic gratuity of 18-20%, that's normal and expected. If it's significantly higher (say, 25% or more), ask your server to explain it — you want to make sure there's no mistake or hidden fee.

Do I Need to Tip on Top of Automatic Gratuity?

In most cases, no. If the restaurant already added 18-20% gratuity, that covers the standard tip for your server and the support staff. You don't need to add more unless:

• The service was exceptional: If your server went above and beyond (personalized recommendations, accommodated special requests, handled a complicated order perfectly), leaving an extra 5-10% in cash is a nice gesture.
• You want to reward specific staff: If the bartender made amazing cocktails or the sommelier gave great wine advice, a cash tip directly to them ensures they benefit from your generosity.
• You're at a high-end restaurant: At fine dining establishments where the service is impeccable, some diners leave an additional 5% on top of the auto-gratuity as a thank-you.

If the service was poor, you can ask to speak with a manager and request an adjustment to the automatic gratuity. However, this is a sensitive conversation — be polite, specific about the issues, and understand that the restaurant may not accommodate your request. In most cases, it's easier to pay the auto-gratuity and simply not return to that restaurant.

Can I Remove or Reduce Automatic Gratuity?

Legally, automatic gratuity is a "service charge" set by the restaurant — it's part of the price you agreed to pay when you ordered. You can't unilaterally decide to reduce or remove it. However, in practice, many restaurants will accommodate reasonable requests, especially if:

• The service was genuinely poor (cold food, long waits, rude staff)
• You were not informed about the gratuity before ordering
• There was a billing error (gratuity added twice, wrong percentage)

If you have a legitimate concern, ask to speak with a manager before you leave. Be specific about the issue and polite in your request. Most managers will adjust the bill to maintain customer goodwill. However, if the restaurant refuses, you're generally expected to pay the service charge as billed.

Important: don't simply cross out the gratuity on your credit card receipt and write a lower amount. The restaurant can (and often does) adjust the charge back to the original amount, and it creates an awkward situation for everyone involved. Address the issue with management directly.

Is Automatic Gratuity Taxable?

Yes, but the tax treatment is different from regular tips. The IRS classifies automatic gratuity as a "service charge," which means:

• For the restaurant: Service charges are considered regular revenue and are subject to sales tax in most states (unlike discretionary tips, which are not subject to sales tax).
• For the staff: Service charges are treated as regular wages for payroll tax purposes. The restaurant must withhold income tax, Social Security, and Medicare from service charges, just like regular pay.
• For you: You pay sales tax on the service charge (if your state taxes it), just like you pay tax on the food itself.

The key difference: with a discretionary tip, the staff reports it as tip income and pays their own taxes. With a service charge, the restaurant handles the tax withholding. From your perspective as a customer, the experience is the same — you pay the money, and the staff receives it.
