A service charge and a tip can show up as the same 18% on a guest's receipt, but they are different money. A tip belongs to the employee and is the guest's free choice. A service charge is a mandatory fee the restaurant sets, which makes it restaurant revenue that the restaurant then pays out as wages, if it chooses to pay it to staff at all.
That difference changes payroll taxes, sales tax, the new federal tips deduction and what you must tell guests. This guide follows one large-party check line by line to show where each rule applies, then covers how to label service charges in your POS and on receipts. The rules below come from IRS Revenue Ruling 2012-18 and the Department of Labor's Fact Sheet #15. State and city rules vary, so confirm with your accountant or state agency.
Revenue Ruling 2012-18 sets out four factors. A payment is a tip only if all of them are true:
An automatic 18% gratuity on parties of eight or more fails the first three factors, so the IRS treats it as a service charge. The label on the check does not change this. Calling it "gratuity" or "auto-tip" still makes it a service charge if the guest cannot choose to pay less.
Follow an illustrative dinner for ten with $800 in food and drink, an automatic 18% service charge and an extra $40 the host adds on the card slip.
The $800 subtotal. This is ordinary sales. Sales tax applies according to your state's rules for prepared food.
The $144 service charge. Because it is mandatory, it is restaurant revenue. In many states a mandatory service charge is also subject to sales tax, which the guest pays along with the food. If you distribute it to staff, the payout runs through payroll as regular wages, with income tax withholding and employer payroll taxes on the full amount.
The extra $40 on the card slip. The host chose to add it and chose the amount, so it is a tip. It belongs to the server, or to the tip pool if you have a valid one. It is reported as tips, it is generally not subject to sales tax, and it can count toward a tip credit where your state allows one.
The same receipt, then, produces three different tax treatments. The POS needs to record them as three separate lines so that sales tax, payroll and tip reports each pick up the right amount. Our article on split checks for large group tables covers how to present the automatic charge to the table before the meal.
Under the Fair Labor Standards Act, a tip is the employee's property. The employer may not keep it, and managers and supervisors may not share in it.
A service charge is different. Fact Sheet #15 explains that a compulsory charge is not a tip, and the employer may use it to meet minimum wage and overtime obligations. That means a restaurant may keep part or all of a service charge, or distribute it to staff in whatever way its policy says, as long as wages still meet the law.
Many restaurants do pay service charges to the staff who served the party, and guests often assume that is what happens. Some states and cities require restaurants to tell guests if a charge that looks like a gratuity is not going to staff. New York, for example, has rules on charges that a guest could reasonably believe are gratuities. If you keep any part of a service charge, say so clearly on the menu and the check.
Treating a service charge as a tip by mistake creates several payroll problems:
If your POS records an automatic gratuity in the same field as card tips, payroll will usually treat both as tips. Separating them is the single most useful fix. Once they are apart, payroll can withhold on service charge payouts in the pay period they are paid, add them to the regular rate for any overtime that week, and leave voluntary tips to the normal tip reporting process.
The federal deduction for qualified tips, available for tax years 2025 through 2028, applies only to voluntary tips. The final regulations exclude mandatory service charges and automatic gratuities. When you report total tips on employees' 2026 Form W-2s, service charge payouts must not be included in the tip total.
This gives restaurants a new reason to review large-party policy. Some owners are replacing automatic gratuities with a suggested tip line on the check, which leaves the amount up to the guest and keeps it a tip. Others keep the service charge for predictability. Either is legal; the choice affects how much of your staff's income qualifies for the deduction.
Clear disclosure prevents most guest disputes and many compliance questions. A practical setup:
California and some cities also have rules on how mandatory fees must appear on menus and in advertised prices. Check local requirements before you add or change a fee. Our guide to card surcharges and cash discounts covers the related rules for card fees.
Most restaurant POS systems handle this through a configurable service charge that applies automatically by party size, order type or table. When you set it up, check that:
The Chowbus POS supports split checks and tableside card payment, and its reports break down sales by order type and period, which helps when you reconcile service charges against payroll.
Q1: What is the difference between a service charge and a tip?
A tip is paid voluntarily, in an amount the guest chooses, and belongs to the employee. A service charge is mandatory and set by the restaurant, so it is restaurant revenue. If the restaurant pays it to staff, it is paid as regular wages through payroll.
Q2: Is an automatic gratuity a service charge?
Yes. Under IRS Revenue Ruling 2012-18, an automatic gratuity that the guest cannot choose to reduce is a service charge, whatever it is called on the check. It should be recorded separately from tips and paid through payroll as wages.
Q3: Does the restaurant have to give the service charge to servers?
Federal law does not require it, since a service charge is the employer's money. Some states and cities require clear disclosure when a charge that looks like a gratuity is not paid to staff. If you keep any part of it, say so on the menu and check.
Q4: Is sales tax charged on a service charge?
In many states, yes, because a mandatory charge is part of the sale. Voluntary tips are generally not taxable. Rules differ by state, so set the tax flag on the service charge in your POS according to your state's guidance and confirm with your accountant.
Q5: Do service charges qualify for the no tax on tips deduction?
No. The final regulations exclude mandatory service charges and automatic gratuities from qualified tips. Only voluntary tips count, so service charge payouts should not be included in the tip total on employees' W-2s.
Q6: Should my restaurant switch from automatic gratuity to a suggested tip?
It depends on your priorities. A suggested tip line keeps the payment a tip, which can qualify for the deduction and the FICA tip credit, but guests may pay less. A service charge gives predictable income but is taxed as wages. Many restaurants test suggested tips on large parties first.
The same 18% can be a tip or a service charge depending on who decides the amount. Once you know which one your restaurant uses, the right tax treatment, payroll setup and guest disclosure follow from it.
Start by checking how your POS records large-party charges today. If they share a field with card tips, separating them before year-end will fix your payroll taxes, your W-2 tip totals and your sales tax reports in one step.
