Ontario’s 20% to iGO: Why It’s a Revenue Share on NGR, Not a Gambling Tax on GGR

Ontario’s 20% iGO payment is one of the most widely mischaracterised financial obligations in Canadian iGaming compliance. It is not a gambling tax. It does not apply to gross gaming revenue in the way that jurisdictions like Brazil structure GGR taxation. It does not flow to provincial tax authorities. It is a contractual revenue share, calculated on a post-deduction revenue base, payable to iGaming Ontario under the terms of an Operating Agreement that every registered gaming operator must execute before accepting a single wager from an Ontario player. Getting this distinction wrong has material consequences for financial modelling, intercompany transfer pricing, regulatory reporting, and competitive benchmarking.

The Conduct-and-Manage Architecture

Ontario’s legal framework for internet gaming rests on Criminal Code section 207(1)(a), which permits a provincial government to “conduct and manage a lottery scheme in that province.” To bring private operators into the market while preserving the provincial Crown’s conduct-and-manage authority, Ontario created a dual-entity architecture. The Alcohol and Gaming Commission of Ontario (AGCO) functions as the regulator, issuing registrations, enforcing the Registrar’s Standards for Internet Gaming, and holding the statutory authority to suspend or revoke access under the Gaming Control Act, 1992. iGaming Ontario (iGO) functions as the commercial counterparty, conducting and managing the lottery schemes that private operators deliver on its behalf.

The critical legal consequence of this design is the principal-agent relationship embedded in every Operating Agreement. Under the terms confirmed in iGO’s financial statements, gaming operators accept bets on eligible online games “on behalf of and as agent for the Corporation.” Operators are also required to pay all winnings to players “on behalf of and as agent for the Corporation.” The operator is legally acting as iGO’s agent in the province. Revenue flows first to iGO as principal, and iGO then pays the operator its share.

On May 12, 2025, iGO was formally constituted as a standalone Crown agency under Schedule 9 of Bill 216, the Building Ontario for You Act (Budget Measures), 2024, enacted as the iGaming Ontario Act, 2024. This dissolved the prior parent-subsidiary relationship between the AGCO and iGO that had existed since iGO’s founding in July 2021. The AGCO remains the regulatory authority, iGO is now a fully independent board-governed agency under the Ministry of Tourism, Culture and Gaming. Compliance teams should update any internal documentation that still describes iGO as an AGCO subsidiary.

What Is the Revenue Base?

Ontario’s 20% iGO share is calculated on gaming revenue, which equals wagers minus winnings minus eligible deductions. It is not calculated on gross gaming revenue (GGR), which would be wagers minus winnings only. The eligible-deductions adjustment is the critical difference, and for operators running active promotional programmes it can shift the revenue base by several percentage points before the 80/20 split is applied.

iGO’s financial statements define eligible deductions as “cashable payments to players derived from the wagering of promotional play funds such as free bets or bonuses dependent on conditions and up to a limit specified in Operating Agreements.” This is the net gaming revenue (NGR) concept familiar to most operators from European markets, and iGO’s own Business Plan labels the adjusted figure “Adjusted GGR (AGGR)” for internal planning purposes.

“The Corporation’s gaming revenue includes the gross amounts, or wagers collected by Gaming Operators from players less winnings paid to players and less eligible deductions. Wagers include rake fees, tournament fees and other fees. Eligible deductions are cashable payments to players derived from the wagering of promotional play funds such as free bets or bonuses dependent on conditions and up to a limit specified in Operating Agreements.”

In FY2024-25, iGO’s total gaming revenue on this basis was CAD $2,901,546,000, against total wagers of $82,743,796,000. The gap between wagers and gaming revenue, approximately $79.8 billion representing winnings and eligible deductions, illustrates the magnitude of the adjustment. iGO retains 20% of gaming revenue, which in FY2024-25 produced net gaming revenue of $574 million. Operators received 80%, recorded by iGO as variable compensation for services delivered.

Line Item	FY2024-25 (CAD $000s)	FY2023-24 (CAD $000s)
Total wagers	82,743,796	63,275,274
Less: winnings and eligible deductions	(79,834,550)	(61,072,813)
Gaming revenue (iGO’s revenue base)	2,901,546	2,199,891
Operator payments (80% of gaming revenue)	(2,327,447)	(1,761,918)
iGO net gaming revenue (20% share)	574,099	437,973

The distinction between AGGR and unadjusted GGR is material to budgeting. A high-volume operator running significant promotional credit programmes will report a meaningfully lower AGGR than its gross wager-to-win position would suggest, and the 20% share applies to AGGR, not to the unadjusted gross.

Why Promotional Credit Deductibility Matters

Operators entering Ontario with significant welcome-bonus or free-bet programmes should model the eligible-deduction mechanism carefully. Cashable promotional payments that meet the Operating Agreement’s conditions reduce the gaming revenue figure before the 80/20 split is applied. Promotional spend is not simply a marketing cost sitting below the revenue share line, it directly reduces the base on which iGO’s 20% is computed.

The practical consequence is that two operators posting identical gross wager volumes can report substantially different gaming revenue figures if their promotional activity levels differ. The operator running a lower-bonus, higher-margin strategy retains a larger absolute amount from the same gross handle, even though both pay 20% of their respective gaming revenue to iGO. Compliance teams negotiating Operating Agreement terms, or advising on promotional programme design, should understand this interaction from the outset.

One constraint applies: eligible deductions are subject to limits specified in the Operating Agreements. Operators cannot construct unlimited promotional credit programmes purely to reduce the gaming revenue base. The Operating Agreement terms cap deductibility, and iGO enforces compliance with those limits through its commercial relationship.

Is the 20% a Tax?

The 20% iGO share is not a tax. It is a contractual obligation under the Operating Agreement between the operator and iGO, a Crown agency acting as the legal principal of the lottery scheme. No statute imposes it as a levy, no revenue agency collects it, no fixed rate applies independently of the commercial terms iGO sets.

The contrast with a genuine gambling tax is instructive. Remote Gaming Duty in the United Kingdom is a 40% statutory levy on GGR under the Finance Act 2014, administered by HMRC, payable regardless of any commercial relationship between the operator and the Gambling Commission. An operator cannot negotiate its rate, vary its base by contract, or structure its relationship with the regulator to alter the levy amount. Ontario’s iGO payment is none of these things.

iGO books the 80% payment to operators as a “cost of earning gaming revenues,” reflecting that the operator payment is variable compensation for services rendered, not a distribution of post-tax profits. iGO itself is exempt from income tax under the Income Tax Act because it is a Crown agency.

“The Corporation remits 80% of the gaming revenue deposited back to each Gaming Operator as variable compensation for the online services they provide to players as iGO’s agent, in accordance with the terms of the Operating Agreement and any related policies.”

For Canadian corporate tax purposes, operators receiving the 80% operator payment report that amount as their gaming revenue for the period. They are not the legal operator of a lottery scheme, they are agents of iGO. This treatment has implications for how operators structure intercompany agreements, particularly where a Canadian subsidiary holds the iGO Operating Agreement and a foreign parent holds the brand and technology IP. Operators should seek qualified legal and tax counsel on the intercompany mechanics before executing an Operating Agreement.

The AGCO Registration Fee: A Separate Cost Layer

The Operating Agreement and the AGCO registration are distinct obligations with distinct cost implications. Registration with the AGCO, and the associated annual fee, sits entirely outside the iGO commercial relationship. The AGCO’s registration regime under the Gaming Control Act, 1992 charges an annual registration fee of CAD $100,000 per gaming site. An operator running multiple brands or “skins” under separate gaming site registrations pays this fee for each site.

The AGCO’s regulatory costs relating to internet gaming are ultimately borne by operators through a recovery mechanism. Under section 12.1 of the AGCO Act, the AGCO is permitted to direct payment from iGO for costs incurred in regulating the internet gaming market. The Operating Agreements between iGO and gaming operators establish that gaming operators are responsible for costs charged by the AGCO in regulating the market, regardless of whether those costs are initially incurred by iGO. Operators therefore carry the AGCO’s regulatory overhead as part of their total cost of market participation, in addition to the per-site registration fee.

The Ontario First Nations Payment

A further downstream payment that operators should understand, even though it does not directly alter their 80% share, is the Gaming Revenue Sharing and Financial Agreement (GRSFA) obligation to the Ontario First Nations (2008) Limited Partnership (OFNLP). Pursuant to the GRSFA, iGO pays OFNLP an amount equal to 1.7% of the prior fiscal year’s unadjusted gross gaming revenue, defined as wagers less winnings without the eligible-deductions adjustment. In FY2024-25, this amounted to $41 million paid from iGO’s retained share.

This payment flows from iGO’s 20% slice, not from the operator’s 80%. Operators do not pay the OFNLP directly. The existence of this obligation reinforces that the 20% iGO retains is not pure government profit: it funds regulatory cost recovery, the OFNLP revenue share, iGO’s operating costs, and a dividend to the Province. In FY2024-25, iGO declared dividends of $181 million to the Province of Ontario after meeting all these obligations.

Comparing Alberta’s AiGC Model

Alberta’s regulated internet gaming market, launched on July 13, 2026 under the iGaming Alberta Act, adopts the same fundamental conduct-and-manage architecture as Ontario. The Alberta iGaming Corporation (AiGC) serves as the operational Crown entity, with the AGLC functioning as regulator. AiGC retains 20% of net iGaming revenue, with 80% allocated to operators, as confirmed in public communications from Alberta.

The Alberta model includes two revenue allocations that sit above the operator’s 80% share: 2% of gross gaming revenue (calculated as bets placed minus winnings paid minus eligible deductions) is allocated to support First Nations communities, and 1% funds social responsibility initiatives. Alberta’s gaming lawyer Ron Segev has noted publicly that Alberta’s revenue structure is “familiar to the market” precisely because it mirrors Ontario’s 80/20 split, with the First Nations and social responsibility carve-outs structured separately at the gross level.

Feature	Ontario (iGO)	Alberta (AiGC)
Revenue share rate (operator)	80% of gaming revenue (NGR)	80% of net iGaming revenue (NGR)
Government’s retained share	20% of gaming revenue	20% of net iGaming revenue
Promotional deductibility	Yes, eligible deductions per Operating Agreement	Yes, eligible deductions per commercial agreement
First Nations allocation	1.7% of prior year’s unadjusted GGR (via GRSFA)	2% of GGR (carved out pre-split)
Social responsibility allocation	Via iGO dividend to Province	1% of GGR (carved out pre-split)
Regulator registration fee	CAD $100,000/site annually (AGCO)	CAD $150,000/year + $50,000 application (AGLC)
Commercial counterparty	iGaming Ontario (Crown agency since May 2025)	Alberta iGaming Corporation (AiGC)
Legal basis	iGaming Ontario Act, 2024, Gaming Control Act, 1992	iGaming Alberta Act, Gaming, Liquor and Cannabis Act

For operators already registered with the AGCO in Ontario, the structural familiarity of Alberta’s AiGC model reduces the conceptual compliance overhead of entering a second Canadian province. The accounting treatment, the agent relationship, and the NGR-based revenue calculation are essentially the same framework. The material differences are in the fee schedule, the responsible gambling technical standards, the self-exclusion integration requirements, and certain product-specific rules. Operators should review the AGLC Standards and Requirements for Internet Gaming in detail before treating Alberta as a straightforward port of their Ontario compliance programme.

What Does the 20% Actually Mean for P&L Modelling?

The 20% iGO share is not equivalent to a 20% GGR tax, and finance teams that model it as one will overstate the cost of participation. On a market generating $3.2 billion in GGR, an operator’s retained share is not 80% of $3.2 billion. The operator’s 80% is calculated against gaming revenue after eligible deductions. Depending on the promotional intensity of the operator’s programme, gaming revenue will typically be 3% to 8% lower than unadjusted GGR for a mid-market operator, and potentially more for a new entrant relying heavily on welcome bonuses to acquire players.

The AGCO registration fee is a fixed cost that scales by site count rather than by revenue. An operator with a single gaming site and CAD $50 million in annual gaming revenue pays the same $100,000 registration fee as an operator with $500 million in gaming revenue on that site. At scale, the registration fee becomes immaterial relative to the revenue share. For smaller operators or for new entrants testing the market with limited promotional budgets, the fixed fee represents a meaningful floor cost before any revenue is generated.

iGO’s FY2024-25 Annual Report confirmed that the market reached $82.7 billion in total wagers, $3.2 billion in GGR, and $574 million in iGO net gaming revenue. The implied blended retention rate against total wagers was approximately 3.5% at the iGO level. For individual operators, the rate against their own wager volumes will vary by product mix, since sports betting, casino, and peer-to-peer poker carry materially different house margins and thus different GGR-to-wager ratios.

Reporting Obligations and the iGO Relationship

The Operating Agreement creates reporting obligations that are distinct from, and in some respects more granular than, the AGCO’s regulatory reporting requirements. Operators must provide iGO with financial and income reporting covering gaming revenue, eligible deductions, and operator payments on a schedule determined by the Agreement. These reports feed directly into iGO’s own financial statements, which are prepared under IFRS and published annually.

Because iGO presents its financials on a gross basis as principal, with operator payments shown as a cost of revenue, operators’ individual revenue figures are aggregated and netted at the iGO level. An operator’s specific gaming revenue contribution is not publicly disclosed in iGO’s reports. However, iGO’s audit scrutiny of the underlying calculations, particularly the eligible-deduction methodology, is a practical compliance risk. Operators whose promotional programme design or eligible-deduction calculations are not clearly grounded in the Operating Agreement’s terms face the risk of recalculation and recovery of underpaid amounts.

The full scope of AGCO registration requirements, including the dual-entity structure, the $100,000 per-site fee, enforcement precedents, and BetGuard integration obligations, is covered in the AGCO registration requirements profile.
