Legal Sports Betting In The Netherlands

The Netherlands legalized online sports betting through the KOA amendment to the Wet op de kansspelen (Betting and Gaming Act). KOA took force on April 1st, 2021, after a process that started back in 2016 and slipped past an original November 2019 target. The online market opened October 1st, 2021, with ten licensed operators approved to take Dutch bets. Those initial licenses run a five-year term through September 30th, 2026. That puts the market in the middle of its first renewal cycle right now. Some names on the list today will re-apply. Some may not clear the bar again.

The whole point of the KOA rollout was channelization: give Dutch bettors already wagering with unlicensed sites a regulated, taxed, locally supervised alternative, so demand that used to flow offshore flows through operators the Ksa can actually oversee. Ten years of delay between the first legalization push and the 2021 launch made that a slow build, but the licensed market now covers the sports a Dutch bettor actually wants to wager on.

Land-based sports betting sits apart from that online license pool. TOTO, run by the state-owned Nederlandse Loterij, holds the retail sports-betting position. Betting shops, kiosks, and terminals carrying the TOTO brand have covered that side of the market for decades, long before any online license existed under KOA rules. ZEbetting & Gaming runs horse-racing pools separately. TOTO also operates online under its own KOA license, so it competes directly against private operators it used to have the field to itself against. Regulators drew a clean line between the two sides on purpose: a retail monopoly that predates the internet, and a competitive online field built from scratch in 2021.

A Dutch bettor’s options run to Ksa-licensed brands. Those are the only operators legally permitted to advertise, accept deposits, and pay out winnings inside the country. The current licensed lineup includes:

Each holds its own KOA license, which means Ksa oversight of how it handles player funds, self-exclusion tools, and deposit limits. That license is also the reason these operators can legally advertise in the Netherlands at all. Unlicensed offshore books do not clear that bar, for reasons covered next.

The lineup mixes backgrounds. TOTO and Holland Casino Online both trace back to state-linked Dutch gaming operations that existed long before the online market opened. bet365 and Unibet arrived as established international operators seeking a KOA license once the market opened up. BetCity built its name as a Dutch-founded sportsbook, and Jack’s Casino & Sports runs as the online arm of JVH’s land-based casino and arcade chain. A bettor comparing them is really comparing six different track records held to one shared regulatory standard.

Every operator on the licensed list runs a regulated mobile app alongside its desktop site, built to the same KOA account-verification and deposit-limit rules as the browser version. Live, in-play wagering is standard across the licensed market too, covering soccer, tennis, and basketball markets that update as a match unfolds. A bettor doesn’t need to pick between convenience and legality here; the licensed operators built both into the same product.

Most offshore sportsbooks that circle other unregulated markets skip the Netherlands entirely, for good reason. The Ksa fines unlicensed operators directly, and it goes after their payment processors and B2B suppliers too. That cuts off the advertising and banking rails an unlicensed site needs to operate here. A Dutch player isn’t prosecuted for using one of those sites. The tax code still finds the transaction, though: in any month winnings from an unlicensed operator exceed stakes, the player owes kansspelbelasting on the difference, self-declared. That’s a deliberate deterrent, not an oversight. It’s one more reason an unlicensed offshore book is a worse trade than a KOA-licensed one, even before counting the missing consumer protections. No offshore sportsbook is named or recommended for Dutch players here.

The Netherlands taxes gambling revenue mainly at the operator level. Ksa-licensed sportsbooks pay kansspelbelasting on gross gaming revenue at 34.2% through the end of 2025. That rate rises to 37.80% from January 1st, 2026, an increase that lands on operator margins rather than a bettor’s bet slip.

Players stay outside that tax as long as they stick to the licensed market. There are two exceptions. Winnings from an unlicensed foreign operator get taxed once stakes are covered, in any given month. Foreign land-based or lottery prizes over 449 euros get taxed too, though EU-based casino and sports operators are exempted from that second rule. A bettor using one of the six licensed names above never files anything extra. A bettor routing money through an unlicensed site takes on a tax obligation the licensed market simply doesn’t create.

None of this shows up on a bet slip. A licensed sportsbook builds its tax cost into its own margins the way any regulated business does, the same way a retail shop prices sales tax into overhead rather than itemizing it line by line. A bettor never sees a separate tax line at checkout with a KOA-licensed operator. The paperwork only starts if that bettor steps outside the licensed pool, which is exactly the outcome the tax rule is built to discourage.

The Dutch market has tightened steadily since its 2021 launch. What a bettor finds today looks different from what existed at kickoff.

• July 1st, 2023 – a ban on untargeted gambling advertising took effect, pulling gambling ads out of public spaces, TV, radio, and print.
• October 1st, 2024 – mandatory deposit-limit intervention rules arrived. An affordability check now kicks in before net deposits exceed 300 euros a month for players 18-24, or 700 euros a month for players 25 and up. Deposits are blocked past that line without it.
• July 1st, 2025 – a gambling sports-sponsorship ban took effect, ending sponsored jerseys, team deals, and competition sponsorships. It was the final phase of the advertising crackdown.
• January 1st, 2026 – the operator tax rate rises to 37.80%.

License renewals for the original ten KOA operators land around September 30th, 2026. That date is worth watching for any Dutch bettor loyal to a specific brand. A license lapsing at renewal would end that operator’s legal Dutch offer.

Soccer dominates Dutch betting interest. The Eredivisie draws steady local action around clubs like Ajax, PSV, and Feyenoord, and English and Spanish leagues pull heavy volume too, the same cross-border draw that shapes sports betting in the United Kingdom. The Netherlands’ spot in northeastern Europe puts every major continental kickoff within easy reach. Basketball, tennis, and Formula 1 round out the rest of the market’s regular betting slate. The bettor base splits between Dutch residents and the steady flow of visitors passing through, which keeps handle high around marquee fixtures and major tournaments.

Open over gokken, the Ksa’s own platform, formerly branded Loket Kansspel, runs a free, anonymous helpline for anyone concerned about their play or someone else’s. Call 0800 24 000 22, available 24/7, or use the WhatsApp and chat options alongside the phone line at openovergokken.nl. Every licensed Dutch operator is required to point players toward it.
