Turnover Tax
A gambling tax levied on the total amount staked rather than on operator revenue — which makes a small headline rate a very large effective burden.
What it means
A turnover tax (also called a stake tax or handle tax) applies to every unit wagered, regardless of whether the player wins or loses. This differs fundamentally from a GGR tax, which applies only to what the operator keeps after paying winnings. Because players recycle the same money many times over a session, stakes vastly exceed revenue — so a turnover tax with a low headline rate can cost far more than a GGR tax with a high one.
Why it matters for operators
Converting a turnover tax into comparable terms takes one division: the tax rate divided by your hold percentage. A 5.3% stake tax against a 4% hold equals 133% of gross gaming revenue, which is a structurally impossible business. Against an 8% hold it equals 66%. This is why operators in stake-taxed markets cut RTP rather than absorb the levy, and why product mix shifts toward higher-hold verticals. Any market-entry model that compares headline rates across differently-based taxes will reach the wrong conclusion.
Example
Germany taxes virtual slots and online poker at 5.3% of stakes. At an international 96% RTP the tax would exceed the entire gross margin, so German slots typically run at 92-94% RTP instead — raising hold to 6-8% and bringing the effective burden down to roughly 66-88% of GGR. The operator nominally pays; the player funds it through a worse-paying game.
