South Africa’s National Treasury published its discussion paper on a proposed national online gambling tax in November 2025. The comment period closed in February 2026, but the debate has continued.
Having tracked South Africa’s licensed operator market for more than a decade, I can say with some confidence that the aspect of the proposal receiving the least attention could have the most direct impact on players.
If the proposed 20% tax on gross gambling revenue (GGR) is introduced in its current form, operators are unlikely to adjust their bottom line first. Instead, their promotional structures are likely to change.
Licensed platforms that players currently compare based on bonus offers, wagering requirements, and payout speeds could begin to look very different. As a result, those comparisons may become even more important.
Gross gambling revenue is the amount an operator retains after paying out winnings. It is not the same as turnover. For example, a player could deposit R1,000, place R5,000 worth of bets, and walk away with R400. In that case, the operator’s GGR would be R600. The proposed 20% national tax would apply to that R600, rather than the R1,000 deposited or the R5,000 wagered.
That distinction is important because the tax base has already been reduced by player winnings before the levy is applied. The proposal raises legal questions surrounding the constitutional position. Treasury is proposing a national tax on an activity that remains technically unlawful at the national level, despite being accommodated through provincial regulation.
The National Treasury discussion paper frames the measure primarily as a social harm levy, following the model of so-called sin taxes on products such as alcohol and tobacco. The projected annual revenue of R10 billion is presented as a secondary consideration.
I understand that approach, and I take the harm-reduction argument seriously. However, the proposal must also be considered alongside existing provincial levies.
These levies already range from 6% to 9% on online betting and 10% to 15% on casino-style games. Adding a 20% national tax would place the combined effective burden between approximately 26% and 35% of gross revenue. Some legal analyses put the potential overall burden closer to 39% once other obligations are taken into account.
That is a level of taxation capable of materially changing operator economics rather than simply adding a marginal cost.
