| No Washington state tax applies. Retail sports wagering is confined to tribal casinos under Class III gaming compact amendments (2020-2021) negotiated pursuant to 2020 Wash. Laws ch. 170 (HB 2638); these compacts have no conventional state revenue-share/tax mechanism comparable to a commercial-operator GGR tax -- unlike many states, Washington's tribal-state fiscal relationship runs the other direction (state B&O/sales-tax and other negotiated considerations), not a sports-wagering-specific state cut of tribal sportsbook revenue.

Rules
- Minimum age to place a sports wager
- 18 · Corrected after fetching WSGC's own "Sports Wagering Requirements and Rules" page directly: it lists "[a]nyone under 18 years of age" as a prohibited sports wagering participant. An earlier pass had assumed the general 21+ tribal-casino gaming-floor age applied to sportsbooks specifically, without a direct source; the regulator's own page sets 18 for sports wagering itself.[3]
- Wagering on college sports allowed at all
- Yes · Confirmed via WSGC's own rules page (fetched directly): wagers on out-of-state collegiate events are allowed, but wagers on Washington collegiate institutions' own events/teams, and on any collegiate event taking place in Washington, are prohibited.[3]
- Esports wagering allowed
- Yes · Confirmed via HB 2638's statutory "sports wagering" definition itself (fetched and parsed directly), which explicitly lists "[a]n electronic sports or esports competition or event."[1]
- New online accounts must be created in person
- Yes · Because mobile play requires presence on tribal casino property, functionally accounts must be used on-site.[1]
- Statutory cap on number of online sportsbook licenses/skins (omit if uncapped)
- 0 · No commercial/non-tribal online sportsbook license category exists; all sports wagering is under tribal compacts.[1]
- Online sports wagering available statewide (not tethered to premises)
- No · Mobile wagering is geofenced to tribal casino premises only, not available statewide.[1]
