South African Breweries has launched a formal pushback against a National Treasury proposal to impose a 20% tax increase on standard beer, warning that the measure would accelerate the growth of South Africa’s illicit alcohol market rather than curb harmful drinking.

The proposal, contained in a National Treasury discussion paper published in November 2024, would see beer with an alcohol content of between 4% and 6% by volume attract higher excise duties under a tiered tax structure designed to steer consumers towards lower-alcohol products. The measure would affect some of SAB’s most commercially significant brands, including Castle Lager, Black Label, Hansa Pilsner, and Castle Milk Stout.
In its submission to Treasury, SAB warned that illicit beers are already 37% cheaper than legal equivalents. A 20% tax hike would widen that gap further, create instability in the standard beer segment — the backbone of excise revenue — and direct price-sensitive consumers towards unregulated products. SAB’s internal projections suggest the measure could wipe more than R2 billion from its sales.
The argument sits within a much larger structural problem. South Africa’s illicit alcohol market is estimated to be worth approximately R25 billion, with roughly one in every five alcoholic drinks sold in the country falling outside the formal, regulated, and taxed system. That figure has been growing, driven by economic pressure on consumers and by the widening price differential between legal and unregulated products — a differential that any significant excise increase would enlarge further.
SAB, through its parent AB InBev, controls between 72% and 77% of South Africa’s beer market. Heineken Beverages — formed through the 2023 merger of Heineken, Distell, and Namibia Breweries — holds a further 15%. Together, the two groups account for more than 90% of formal beer sales. For SAB in particular, the standard beer segment targeted by the proposed tax is not a niche product category — it is the core of its South African business.
The public health case for the tax is, by most independent assessments, strong. According to research from the University of Cape Town’s Research Unit on the Economics of Excisable Products, alcohol consumption contributes to more than 37,000 preventable deaths annually in South Africa, accounting for roughly 7% of all deaths. South Africa ranks fifth globally for alcohol consumption per capita, and the country has the highest prevalence of foetal alcohol syndrome among 180 countries studied. Alcohol-related harm is estimated to cost the country between 10% and 12% of GDP each year — a figure that dwarfs the industry’s own economic contribution of 3.6% of GDP. Research cited by health advocates found a 60% reduction in femicides during the Covid-19 alcohol ban, with alcohol implicated in roughly half of all homicides, two-fifths of rapes, and approximately a quarter of road fatalities attributed to driver error.
Treasury has been explicit that the proposed reform is primarily a public health intervention rather than a revenue measure. Officials have stated that the proposal is still under active stakeholder consultation, and that revenue estimates will only be provided once the framework is finalised. A virtual technical workshop was held on 4 June 2026 for industry and civil society submissions.
The academic evidence, however, complicates the industry’s position without fully endorsing Treasury’s specific design. UCT’s REEP researchers support the principle of tiered taxation but argue that Treasury’s proposed thresholds — set at 2.5% and 9% alcohol by volume — are poorly calibrated for the South African market, where more than 95% of beer by sales volume falls within the 4% to 6% alcohol range. As a result, the current proposal is unlikely to incentivise meaningful reformulation by producers or meaningful reductions in alcohol content among consumers. REEP has proposed tighter tier thresholds — at 2.5%, 3.5%, and 4.5% — that would create stronger commercial incentives for producers to reduce the alcohol content of their products.
The 2026 Budget, delivered by Finance Minister Enoch Godongwana in February, offered a partial read of the political dynamics at play. Rather than implementing structural reform, the budget locked in a 3.4% increase in alcohol excise — a figure tied to inflation and well below what health advocates had sought. A 340ml can of beer increased by just 8 cents. The outcome reflected sustained industry lobbying against above-inflation increases in the months preceding the budget.
The Southern African Alcohol Policy Alliance has come out in support of Treasury’s tiered approach, arguing that higher taxes on stronger products are consistent with both international best practice and South Africa’s public health obligations. The World Health Organisation classifies alcohol taxation as among the most cost-effective interventions available to governments seeking to reduce alcohol harm.
The alcohol beverage industry contributed R226.3 billion to South Africa’s GDP in 2022, supporting one in every 31 jobs in the country. The tax haul from the sector that year alone was R96.9 billion — enough, by Quantec’s calculations, to fund more than 470,000 teachers. SAB itself operates seven breweries and 42 depots in South Africa, employs approximately 5,000 people directly, and says its beer economy supports more than 250,000 jobs across the supply chain.
That economic footprint is the foundation of the industry’s political argument: that aggressive tax increases risk destroying legitimate employment, suppressing formal tax revenue, and surrendering market share to an illicit economy that the state has so far proven unable to contain. It is an argument that has worked before. Whether it works again — in a fiscal environment defined by constrained revenues, deteriorating public health metrics, and a National Treasury that has explicitly framed this reform as a health intervention rather than a commercial one — will determine whether South Africa’s most consumed alcoholic product becomes significantly more expensive, or whether the policy retreats again to the margins.
