GGR Tax (Gross Gaming Revenue Tax)

GGR Tax (Gross Gaming Revenue Tax) is a fiscal charge levied by gaming regulators on the gross gaming revenue an operator generates within their jurisdiction. GGR is defined as total wagers placed minus total winnings paid out to players, before any operational costs are deducted. Governments use GGR-based taxation because it directly captures the economic margin of gambling activity, making it easier to audit than profit-based taxes.

The relationship between GGR tax and NGR is critical for affiliate program design. NGR is typically calculated as GGR minus bonuses, payment-processing costs, chargebacks, and GGR tax itself. Because RevShare commissions are almost universally calculated on NGR rather than GGR, the GGR tax rate directly reduces the base against which affiliates earn. An operator in the UK — where the Point of Consumption tax rate stands at 21% — will have a materially lower NGR per unit of GGR than an operator licensed in Malta at 5%.

Jurisdictional tax rates span a wide range. Malta's Gaming Authority charges a flat 5% GGR tax on B2C operators. The UK Gambling Commission's POC tax is 21% on remote gaming revenue. In the US, state-level taxes vary dramatically: Pennsylvania charges 54% on slots GGR and 16% on table games, while Michigan applies 8.4%. Ohio doubled its sports wagering tax rate in 2024, and New York's 51% effective rate is among the highest globally.

GGR tax has knock-on effects across the affiliate commission structure. Operators in high-tax markets often widen commission hold periods, introduce NGR-floor clauses, or cap RevShare percentages to protect unit economics. Understanding how GGR tax flows through the P&L — from gross wager to GGR to taxed GGR to NGR to affiliate-eligible NGR — is essential context for any operator building a sustainable commission strategy.
