Tipping in the USA: How Much and When — a Custom, Not a Law
Tipping in the US is a deeply established social custom, not a law — but skipping it in certain settings is treated as a real social offense.
In short: Tipping in the US is a deeply established social custom, not a legal requirement. The common practice at full-service restaurants is generally 15% to 20% of the pre-tax bill, but that's a widely used social norm, not a figure set by law. Skipping a tip where one is expected is treated as a genuine social offense, since many workers actually rely on it as part of their income.
Why does tipping matter so much specifically in the US?
The key difference between the US and many Arab countries is that federal wage law allows employers to pay a lower base cash wage to workers who regularly receive tips (like restaurant servers), as long as tips make up the difference to the full regular minimum wage. In other words: in some jobs, a tip isn't an "extra bonus" — it's an expected, essential part of the worker's income, and skipping it entirely can effectively mean that worker earned below minimum wage that shift. For the official details of this system, see our minimum wage by state guide.
Common percentages by type of service
No federal law sets a required tip percentage for any service; every figure below is a widely followed social custom, not an official standard:
| Service | Common customary percentage or amount | Note |
|---|---|---|
| Full-service restaurant (seated, server takes your order) | 15%-20% of the pre-tax bill | Usually calculated on the pre-tax amount; the percentage is often suggested automatically on the payment terminal |
| Coffee shop or counter order | Nothing to 10%, or rounding up | A much lighter custom than full table service |
| Food or grocery delivery | Often a flat amount or a percentage the app suggests at checkout | Especially encouraged in bad weather or for long distances |
| Taxi driver or rideshare (Uber/Lyft) | Roughly 10%-15%, or an amount the app suggests | Optional but customarily expected for good service |
| Hair salon or barber | 15%-20% of the service cost | Usually handed directly to the stylist or barber |
| Hotel (bellhop, room service, housekeeping) | A small flat amount per service | Usually left in cash in the room or handed directly |
These figures are shifting social customs that vary somewhat by city and venue type, not fixed official rates; treat them as a general guideline, not a strict rule.
How do you actually pay a tip?
- By card: most modern payment terminals at restaurants and cafes show ready percentage options (like 15%, 18%, 20%) before you finish paying; pick a percentage or enter a custom amount.
- In cash: still a perfectly accepted option, especially for delivery drivers or hotel bellhops.
- On a paper check: at some traditional restaurants, you write the tip amount by hand in the "Tip" line on the card receipt, then add up the total and sign.
Are tips taxable?
Yes. The IRS states that all cash and non-cash tips a worker receives count as income subject to federal income tax, and are usually also subject to Social Security and Medicare taxes. If you work in a tip-dependent job, you must report all cash tips to your employer unless the total is less than $20 a month from that employer, and you must include all tips on your annual tax return even if you never reported them to your employer. See our US taxes guide for how this fits into your return.
Does the custom differ by city or region?
To some extent, yes. In major cities with a higher cost of living (New York, San Francisco, Chicago), people tend to tip toward the higher end of the common range (18%-20%), while in smaller cities 15% may be closer to the norm. This is an informal cultural difference, not a strict rule to rely on — use the general range in the table above as a safe reference anywhere.
Services where a tip usually isn't expected
Just as it's useful to know where a tip is expected, it helps to know where it usually isn't, so you don't feel awkward offering one in the wrong setting or having it declined:
- Cashiers at big-box stores and supermarkets: no tip expected at all.
- Bank tellers and government office staff: tipping isn't accepted in this context and can come across as inappropriate.
- Doctors and nurses at a clinic: no tipping custom in healthcare settings.
- Self-service gas station attendants: not expected, except in the few states that require pump service by an attendant.
- Delivery from a big retailer (furniture, appliances): varies by company; some prohibit their staff from accepting tips, so ask if you're unsure.
What do you do when you're not sure?
If you find yourself unsure whether a tip is expected, here's a simple practical rule:
- Check the payment terminal first: if an automatic tip option appears on screen, that's a strong sign the custom is expected there.
- Notice the type of service: direct personal interaction (a server, barber, driver) leans toward expected; fully self-service (an automated kiosk) leans toward not expected.
- Just ask if you need to: asking "is tipping expected here?" is never awkward in American culture, and staff are used to hearing it from new visitors.
- When in doubt, choose the lower end of the range rather than skipping it entirely: a small tip is socially better than leaving nothing at all in a setting where the custom is expected.
Common mistakes new arrivals make
- Leaving no tip because your home country doesn't practice this custom: can be read as a deliberate insult at a restaurant or salon, not simple cultural unfamiliarity.
- Confusing a mandatory service charge with an optional tip: sometimes leads to accidentally tipping twice.
- Calculating the tip after tax instead of before: the common custom bases it on the pre-tax amount, so check which one the terminal in front of you is using.
- Assuming tipping is entirely optional everywhere: legally true, but socially expected in specific services like restaurants and salons, and skipping it repeatedly gets noticed.
- Forgetting to tip on food delivery in bad weather: one of the situations where a higher-than-usual tip is most expected.
What's next?
You don't need to memorize every exact percentage; treat 15%-20% at restaurants as a generally safe rule, and check the table above when unsure about any other service. If you're planning your monthly budget, see our cost of living guide for how tipping fits into your daily spending, and if you yourself work in a tip-dependent job, see our job search guide for the US.
Frequently asked questions
Is tipping legally required in the US?
No, tipping is a social custom, not a legal requirement. Some restaurants add a mandatory 'service charge' clearly printed on the bill for large groups, which is different from optional tipping.
What's the usual restaurant tip?
There's no law setting a percentage, but the common custom at full-service restaurants is generally 15% to 20% of the pre-tax bill — a social norm, not an official figure.
Should I tip delivery drivers too?
Yes, by custom it's expected to tip food and grocery delivery drivers, and most apps suggest a percentage or amount at checkout.
Why do some workers depend on tips for their income?
Because federal law allows employers to pay a lower cash wage to workers who regularly receive tips, as long as tips make up the difference to the regular minimum wage; see our minimum wage guide for the official details.
Do I tip by card or cash?
Both are accepted; most modern payment terminals automatically show a tip option as a percentage when you pay by card.
What if the service was genuinely bad?
You can reduce or skip the tip for genuinely bad service, but that's a social exception used carefully, not a routine rejection of the custom.
