Ontario iGaming tax works differently from a headline gambling levy. The province takes its main cut through a 20% revenue share, not a gaming tax on turnover. Holders of an Ontario iGaming licence pay that share to iGaming Ontario. They also pay federal and Ontario corporate income tax on the profit they keep. Players sit outside almost all of it. This guide sets out what the operator owes and how GST and HST apply. It also covers whether promotional play reduces the taxable amount, and when a player has to declare winnings.
Key takeaways
- Regulator: Alcohol and Gaming Commission of Ontario (AGCO); iGaming Ontario (iGO) holds the operating agreement
- Revenue share: 20% of gross gaming revenue paid to iGO, a contractual share rather than a tax
- GST/HST: the operator revenue-share payment carries a 13% HST charge that iGO self-assesses and remits
- Corporate income tax: 26.5% combined federal and Ontario general rate on active business income
- Player winnings: the Canada Revenue Agency does not tax recreational gambling winnings
- Scope: the rules apply to play by users located in Ontario only
How Ontario iGaming tax works for operators
The Ontario iGaming tax picture for an operator has three layers, and they stack rather than replace each other. First comes the 20% revenue share paid to the province through iGaming Ontario. Then comes GST or HST, which attaches to the revenue-share payment under a specific mechanism. Finally comes corporate income tax on whatever profit remains.
None of these is a single “gaming tax” in the way some jurisdictions charge one. Ontario built its model on a contractual share plus the ordinary Canadian tax system. So an operator that models only the 20% share will understate its total obligation. The AGCO registration fee sits alongside all of this, and our Ontario iGaming licence cost breakdown sets out that fee schedule in full.
The starting point for every layer is gross gaming revenue. That means player wagers less the winnings paid back to them. Understand how the province defines that figure and the rest of the Ontario iGaming tax calculation follows from it.
The 20% revenue share to iGaming Ontario
The largest payment an operator makes is the 20% revenue share, and it is not a tax in the legal sense. Instead, it is a contractual charge set in the operating agreement between the operator and iGaming Ontario. The operator earns a share of revenue, and the province keeps 20% of gross gaming revenue for conducting and managing the market.
The mechanics matter for cash flow. iGaming Ontario holds the gross gaming revenue first, then pays the operator 80% as compensation under the agreement. So the operator never collects the full amount and remits a slice afterwards. For the market-wide numbers behind that split, the Ontario iGaming revenue figures show what operators have kept since launch.
Because the share tracks gross gaming revenue and not turnover, a high-volume sportsbook and a casino brand can owe very different amounts on similar handle. If the two-body structure is new to you, our guide to how the iGaming Ontario model works explains how the AGCO and iGO roles fit together.
GST and HST treatment for iGaming operators
This is the part of Ontario iGaming tax that most guides skip, and it works in an unusual way. Under Ontario’s framework, iGaming Ontario counts as the entity that supplies the gaming service to the player, not the operator. Ontario treats the operator as a distributor that supplies services to iGO.
That structure changes who accounts for the tax. The operator does not charge HST on the revenue-share payment it receives from iGaming Ontario. Instead, iGO self-assesses and remits HST on the services it buys from operators. In its 2024-25 annual report, iGaming Ontario recorded 304 million CAD of GST and HST on operator payments, paid to the Canada Revenue Agency.
The Ontario HST rate is 13%. Operators still register for GST/HST for their other taxable supplies and inputs. So the distributor treatment does not remove them from the system entirely. You can read the AGCO position on the application of Harmonized Sales Tax before you finalise a tax structure. Non-resident operators dealing with iGO also confirm their registration position early, because the treatment turns on the operating agreement.
Corporate income tax for Ontario iGaming operators
After the revenue share and the HST mechanism, an operator still pays corporate income tax on its profit. Canada charges this at two levels. The federal general rate is 15%, and the Ontario general rate is 11.5%, for a combined 26.5% on active business income.
Most licensed operators pay the general rate rather than the small-business rate. The lower small-business rate applies only to Canadian-controlled private corporations on their first 500,000 CAD of active business income. A foreign-owned or large operator does not qualify. That means the 26.5% combined figure is the working assumption for the typical Ontario market entrant.
Corporate tax applies to profit, not revenue. So the 20% share and operating costs come out before tax is calculated. You can confirm the current provincial rate on the Ontario government’s corporate income tax page. Our accounts and audit support covers the corporate filing side for operators entering Canada.
What counts as taxable gaming revenue
Operators often ask whether promotional play reduces the revenue on which the 20% share is calculated. In Ontario, the answer is a qualified yes. The audited gaming revenue figure is wagers less winnings paid, less eligible deductions.
Those eligible deductions include cashable payments derived from promotional funds, such as free bets, up to limits set in each operating agreement. So a free bet that converts into a withdrawable balance can reduce reported revenue, but only within the cap the agreement sets. Non-cashable bonus mechanics work differently.
This distinction explains why two revenue figures circulate for the same period. The monthly market report is unaudited and gross of some promotional cost, while the audited accounts net it off. For an operator, the practical point is simple. Model the 20% share against audited gaming revenue, and confirm your promotional deduction limits in the operating agreement before you build the plan.
Do players pay tax on gambling winnings in Ontario
Recreational players do not pay tax on gambling winnings in Ontario. The Canada Revenue Agency treats casual gambling winnings as a windfall rather than income. So a player who wins on a licensed Ontario site keeps the full amount and declares nothing. This is the same treatment that applies at a land-based casino.
Professional gamblers are the exception. The CRA can treat winnings as business income when a person runs gambling as a business, follows a system and expects to make a profit. In that case the player files a return and pays tax at their applicable federal and provincial rates. The threshold is fact-specific, and the CRA looks at frequency, skill and organisation.
One further point catches players out. Interest earned on winnings held in an account is taxable, even though the winnings themselves are not. The prize is a windfall; the investment income it later generates is not.
The full Ontario iGaming tax and fee picture
The table below sets out where each charge lands, who receives it, and how it is calculated. Figures marked variable depend on the operator’s structure and performance, so treat them as budget lines rather than fixed quotes.
| Charge | Paid to | Basis |
|---|---|---|
| Revenue share (20%) | iGaming Ontario | Gross gaming revenue after eligible deductions |
| GST/HST (13%) | Canada Revenue Agency | Self-assessed by iGO on operator payments |
| Corporate income tax (26.5%) | Federal and Ontario governments | Net profit, general active business rate |
| AGCO registration fee | AGCO | CAD 100,000 per gaming site, per year |
| Player tax on winnings | None for recreational play | Windfall, not taxed by the CRA |
Read together, these lines show why the 20% share is only the first entry in the Ontario iGaming tax total. The share reduces gross revenue, HST is handled through the distributor mechanism, and corporate tax then applies to what remains. Operators serving more than one province split these figures by market, and our gaming operator tax obligations guide explains how a revenue share sits alongside corporate tax across jurisdictions.
How Ontario compares with other Canadian markets
Ontario tax rules stop at the provincial border. An Ontario registration authorises play by users located in Ontario, so the 20% share and the HST mechanism apply to Ontario revenue alone. Revenue from players in another province falls under that province’s framework.
Alberta has legislated its own private online market, which requires a separate registration and carries its own charges. An operator that wants Alberta players registers there through the Alberta iGaming licence route, and keeps its Ontario and Alberta figures separate from the first month. Because the tax and revenue-share treatment differs by province, a multi-market operator cannot assume one set of numbers carries across. Our ongoing licensing compliance service keeps each jurisdiction’s reporting distinct.
Planning your Ontario tax position before entry
The 20% revenue share, the 13% HST mechanism and the 26.5% corporate rate are the three numbers that define Ontario iGaming tax for an operator. Confirm which of them apply to your structure before you file, because your entity structure determines both the HST treatment and the corporate rate.

Frequently asked questions
Is the 20% paid to iGaming Ontario a tax?
No. It is a contractual revenue share set in the operating agreement between the operator and iGaming Ontario, not a levy under tax legislation. It is calculated on gross gaming revenue, meaning player wagers less winnings paid out, after eligible deductions. Corporate income tax then applies separately on the operator’s profit.
Do Ontario iGaming operators pay GST or HST?
The operator does not charge HST on the revenue-share payment it receives. Instead, iGaming Ontario counts as the supplier to players and self-assesses the 13% HST on operator payments. iGO recorded 304 million CAD of GST and HST on those payments in 2024-25. Operators still register for GST/HST for their other taxable supplies and inputs.
What corporate tax rate applies to an Ontario iGaming operator?
The combined general rate is 26.5%, made up of the 15% federal rate and the 11.5% Ontario rate on active business income. Most licensed operators pay this general rate rather than the small-business rate, which only applies to Canadian-controlled private corporations. Corporate tax is charged on profit after the revenue share and operating costs.
Do players pay tax on online casino winnings in Ontario?
Recreational players do not. The Canada Revenue Agency treats casual gambling winnings as a windfall rather than taxable income, so there is nothing to declare on a normal return. Professional gamblers who run gambling as a business are the exception and pay tax on their winnings.
Can operators deduct promotional play from the revenue share?
Partly. Cashable payments derived from promotional funds, such as free bets, count as eligible deductions when calculating gaming revenue. Each operating agreement sets a limit on that deduction. Non-cashable bonus mechanics work differently, and the 20% share applies to the net figure after eligible deductions.
Does the AGCO registration fee attract HST?
No. Harmonized Sales Tax does not apply to AGCO registration fees, so the published figure of CAD 100,000 per gaming site is the amount payable. The revenue share and corporate tax are separate charges. The registration fee is also non-refundable if an application is withdrawn or refused.
How is a non-resident operator taxed in Ontario?
A non-resident operator inside the Ontario framework deals with iGaming Ontario under an operating agreement, and the same distributor treatment for HST applies. The corporate tax position depends on how the entity is structured and whether it carries on business in Canada. Non-resident operators should confirm both the HST and corporate positions before signing the operating agreement.
Does an Ontario registration cover tax in other provinces?
No. Ontario tax and the 20% revenue share apply to play by users located in Ontario only. Revenue from players in another province falls under that province’s own rules, and Alberta operates a separate private market with its own registration. Multi-market operators keep their figures split by jurisdiction.
