Are Service Charges and Auto-Gratuity Legally Tips?
Last reviewed
The four-factor test
The IRS spelled out the test in Revenue Ruling 2012-18. A payment is a tip only if all four are true:
Free from compulsion
The customer could have paid nothing extra without consequence.
Customer sets the amount
Nobody else decided the number, including a suggested percentage the customer felt pressured to follow.
Customer picks the recipient
The customer, not house policy, generally determines who gets it.
Not set by policy
It isn’t a fixed amount the business attaches to certain checks, like parties of a set size.
Fail even one of these and the payment is a service charge, not a tip, no matter what the receipt calls it.
Why “auto-gratuity” is usually a service charge
A mandatory 18% or 20% added to every check over a party size is the textbook example. The amount wasn’t the customer’s choice, so it fails the test on that basis alone. The IRS confirmed this directly in Revenue Ruling 2012-18: an “automatic gratuity” is legally a service charge. Whatever the business later chooses to pay staff out of that charge is wages, not a tip, from the moment it’s collected.
The label on the receipt doesn’t decide it
| Tip | Service charge | |
|---|---|---|
| Who sets the amount | The customer | The business |
| Voluntary | Yes | No |
| Who owns it first | The employee | The business |
| How it’s taxed when paid to staff | Special tip reporting rules | Ordinary wages |
| Counts toward the FICA tip tax credit | Yes | No |
Why it matters for your payroll, not just your receipts
No FICA tip credit
The federal tax credit under IRC section 45B only applies to reported tips. A restaurant that converts to mandatory service charges and pays staff from them loses that credit on that money. It’s a real, recurring cost some owners don’t expect.
Withholding timing differs
Service charges paid to employees are ordinary wages, withheld like any other paycheck income. Tips follow the IRS’s separate tip income reporting rules.
California looks past the label
California courts don’t stop at “was it mandatory.” In O’Grady, the court held that a charge can be treated as a tip even if it’s technically a mandatory service charge, as long as a reasonable customer would understand it as a gratuity based on how it’s described on the menu or the check. Naming and presentation matter a lot more in California than they do under the federal test, so calling a mandatory charge a “gratuity” on the check can undercut your own position that it’s a service charge.
