Casino Slang Terms Behind Markers, Credit and Tax Forms
Marker, name credit, W-2G: the casino words that mean debt or tax, defined by Nevada regulators and the IRS instead of a one-line glossary.
The deal
Most casino slang terms are harmless nicknames, but a few of them point at paperwork that moves real money. A "marker" is casino credit you owe, "name credit" is the same debt wearing a hoodie, and a big enough win can put an IRS form in your hand before you reach the parking garage.
Dictionary-style glossaries give each of these one line. The definitions that actually decide what a player owes come from regulators, so that is where this one starts.
Round 1: Why some casino slang is really paperwork
The slang worth learning first is the slang with a legal definition behind it. Words for lucky streaks and bad beats change nothing about your balance. Words for credit and tax reporting do, because a regulator or the IRS has already written down what they mean.
Three of them do most of the damage when misunderstood: marker, name credit and credit instrument. A fourth, the W-2G, is the tax form waiting at the other end of a good night.
Round 2: Marker: the casino's word for your IOU
A marker is a slip that records casino credit you have been given, which makes it a loan, not chips. The Nevada Gaming Control Board says any form showing credit against a limit counts as a marker under its table games internal control standards (the MICS).
So it does not matter what the pit boss calls it or how casual the signature felt. If the paper shows credit issued against your approved limit, the regulator files it under one word, and that word means you borrowed.
Round 3: Name credit: same debt, different nickname
"Name credit" sounds like a friendlier, looser arrangement. Under Nevada's standards it is not. The Control Board's table games FAQ says an instrument a player is not allowed to pay off in the pit can be called a name credit instrument, but the standards still refer to it as a marker.
Reality check: a different nickname does not create a different kind of debt. Whatever the floor calls it, the rulebook treats it the same way.
Round 4: Credit instrument: the legal name for the debt
"Credit instrument" is the term the law uses for the paper behind a marker. Nevada statute defines a credit instrument as a writing evidencing a gaming debt owed to a nonrestricted licensee, and the definition also covers any writing taken to consolidate, redeem or pay off an earlier one.
That last part matters. Rolling an old marker into a new one does not make the debt disappear into slang. The replacement paper is a credit instrument too.
Round 5: Hitting big: the tax terms nobody puts in the glossary
When a win is large enough, the word you hear at the cage is "W-2G," the IRS form for reporting gambling winnings. The numbers below come from the IRS instructions for Form W-2G dated January 2026.
| Term or trigger | What it means for your money | Applies to |
|---|---|---|
| W-2G reporting threshold | Minimum of $2,000 for payments made in calendar year 2026 | Reportable gambling payments |
| Regular gambling withholding | Federal tax withheld when winnings minus the wager exceed $5,000 and winnings are at least 300 times the wager | Bets such as sports wagers |
| No regular withholding | The IRS says withholding doesn't apply to slot winnings | Slot machines, keno and bingo |
Thresholds like these change, so treat them as current as of January 2026. And no withholding is not the same as no tax: it only means the casino is not taking a cut before handing over the payout.
Round 6: The regulars ask
What are some common terms used in casinos?
Plenty are pure nickname, but the ones that touch your money have official meanings: a marker is casino credit you signed for, name credit is the same thing under Nevada's table games standards, a credit instrument is the legal word for that gaming debt, and a W-2G is the IRS form a big enough win can trigger.
Is name credit different from a marker?
Not under Nevada's rules. The Gaming Control Board says an instrument a player cannot pay off in the pit can be called a name credit instrument, but its table games standards still call it a marker.
Does a casino report big wins to the IRS?
It can. For payments made in calendar year 2026 the minimum Form W-2G reporting threshold is $2,000, as of the IRS instructions dated January 2026.
Do slot jackpots have tax withheld?
Regular gambling withholding does not apply to slot, keno or bingo winnings, according to the IRS. That is about withholding at the cage, not about whether the win counts as income.
