Higher state tax burdens get passed directly to bettors through wider vig. That's the short version. When a state levies a steep tax on gross gaming revenue, sportsbooks protect their margins by shading lines from the standard -110 out to -115 or even -120. The math isn't abstract — it costs real money over a full season of action.
Why do some states see -115 or -120 instead of -110?
The vig exists because the combined implied probabilities of both sides always exceed 100% — that's how a sportsbook guarantees itself a cut regardless of outcome. At the standard -110 price, each side carries a roughly 52.4% implied probability, meaning a bettor must wager $110 to win $100. Stack a high state tax rate on top of the operator's existing margin and -110 no longer covers the nut. So the book pushes to -115 or -120, widening the overround and shifting more of that tax burden onto the bettor quietly, through the line itself rather than an explicit fee. New York's comparatively high tax environment is a commonly cited example of a market where bettors routinely encounter lines stiffer than the national baseline.
What does that actually cost over a season?
The difference between -110 and -120 sounds small on a single game. It isn't, compounded across a season. At -110 a bettor needs to win 52.4% of bets just to break even. At -115 that threshold climbs. At -120 it climbs further still — each tick widens the gap a bettor has to overcome before a single dollar of profit appears. Run 200 bets over an NFL season and that extra juice adds up to a meaningful dollar figure drained from the bankroll before talent, research, or luck even enters the picture.

Does this show up on even-money and pick 'em games too?
Yes, and it's sneakier there because bettors assume "even" means no edge for the house. In high-tax states, a game that would be priced -105/-105 elsewhere might open at -110/-110 or worse. The vig hides in the symmetry. Pick 'Em Moneyline Bets: How Vig Hides in Even-Money Lines breaks down exactly how that works and why it catches casual bettors off guard.
Does the vig stay fixed or does it move during the week?
Lines shift constantly. A -115 opener can drift to -120 by kickoff as money flows in or injury news breaks. Sometimes it moves the other direction. Either way, the vig embedded in that line moves with it. Line Movement and Vig: How Real-Time Odds Shifts Increase Your Cost covers how those real-time changes affect the actual cost of getting down on a game.
How do bettors fight back against inflated state-level vig?
Line shopping is the primary tool available. No single book is always best — FanDuel, DraftKings, BetMGM, Caesars, bet365, and BetRivers all price the same game differently at any given moment, and in a high-vig market finding -110 at one book instead of -120 at another is a genuine edge recovered. Line Shopping for Moneyline Odds Across FanDuel, DraftKings & More walks through how to build that habit efficiently. Availability of these books varies by state — legal online sports betting operates in a specific list of states as of 2025 and not all operators hold licenses in every legal market.
| Line | Breakeven Win % | Wager to Win $100 |
|---|---|---|
| -110 | ~52.4% | $110 |
| -115 | ~53.5% | $115 |
| -120 | ~54.5% | $120 |
