Guide · Wedding vendor tipping
Is your vendor’s service charge a tip?
Your caterer’s contract carries a 20% line called a service charge, and it is natural to read that as the tip already handled. The IRS runs a two-part test for exactly this question, and a mandatory contract line fails both parts of it.
The short answer
No. The IRS’s own guidance is direct about what separates the two: “a payment is a tip only if the customer voluntarily decides to pay it and determines the amount.” sourcedA mandatory percentage a vendor writes into their contract fails on both counts — you didn’t decide to pay it, and you didn’t set the number. That makes it a service charge, and a service charge is the vendor’s revenue rather than a gratuity, whether or not any of it reaches the people who worked your wedding.
The test, in the IRS’s own words
The IRS’s tip recordkeeping guidance illustrates the line with a restaurant example: a customer left free to enter any amount on the tip line, or leave it blank, is paying a tip “because Jackie was free to enter any amount on the tip line or leave it blank” and “Jackie and Restaurant did not negotiate the amount nor did Restaurant dictate the amount.” sourcedFlip either condition — the business sets the number, or payment isn’t optional — and the same document reclassifies it. Its own example of a service charge is “automatic charges added to a bill (for example, a mandatory 18% charge for large parties),” which is structurally the same thing as a wedding caterer’s contract line, just at a different scale. sourced
Where the money actually goes
The distinction isn’t academic, because of what the IRS says happens next. Service charges “are generally treated as wages paid by the employer to the employee rather than tips paid by the customer,” and are “income to the employer regardless of whether the employer distributes all or a portion of the service charges to employees.” sourcedIn plain terms: the venue or caterer is not obligated to pass a dollar of it to your waitstaff. They might. Many do, as ordinary wages built into staffing costs. But nothing about the charge itself guarantees it, which is the opposite of what most couples assume when they see “gratuity” or “service” printed on the invoice.
What this looks like on a real invoice
A $12,000 food-and-drink bill with a “they were great on the day” reading of The Knot’s published 15–20% catering band lands at 17.5% — $2,100. If that 17.5% is already a mandatory line on the contract, it’s a service charge under the test above, not a tip, and every dollar of it is the caterer’s to distribute or not. This site’s wedding-vendor calculator keeps that $2,100 in your running total — because the caterer will expect it either way — while flagging it as a service charge you should ask about rather than a gratuity you can assume is settled. house judgment— the $12,000/17.5%/$2,100 figures are the calculator’s own computed output, not a separate estimate.
What this doesn’t mean
- It doesn’t mean you owe a second tip on top of the service charge.Whether the staff already received fair pay through that charge is between you and the vendor to ask about — the guide and the tool both say “ask, then decide,” not “pay twice.”
- It doesn’t apply to a written gratuity clause.If your contract states in writing that gratuity is included — a distinct, specific representation, not just a line item labeled “service” — this site’s calculator treats that as settled and renders the line at $0 rather than flagging it. The two clauses look similar on a page and mean opposite things.
- It isn’t a claim about any specific vendor’s intent. Many venues do pass service charges through as staff wages. The test only says the charge itself is not, legally, a tip — not that the money vanishes.
So what do you actually owe, vendor by vendor?
The wedding vendor tip calculator prices every vendor from The Knot’s published ranges, reads each contract’s gratuity clause as its own input, and keeps a service-charge line in the total while flagging it to ask about — so you know exactly which envelopes are settled and which ones need a question first.
