Nigeria’s sugar tax has been steadily eroded by inflation, prompting the Senate to back a new approach to taxing sweetened drinks. Lawmakers approved replacing the long-standing flat levy with a percentage-based charge linked to retail prices, a change that could push up the cost of soft drinks for consumers.
How inflation weakened the sugar tax
The existing excise duty of N10 per litre on sugar-sweetened beverages has lost much of its bite as inflation reduced its real value over time. Analysts say the fixed rate no longer raises meaningful revenue or strongly discourages consumption. By tying the levy to a share of price instead of a fixed amount, the Senate aims to stop inflation from quietly hollowing out the tax year after year.
The public-health rationale
Backers of a stronger sugar tax point to rising cases of non-communicable diseases such as diabetes, obesity, hypertension and cardiovascular conditions. They argue that higher prices can nudge people toward healthier choices while generating funds for health needs. Sugary drinks are widely consumed in Nigeria, making them a common target for this kind of health-focused taxation around the world.
Industry pushback
Manufacturers and some business groups have opposed an additional burden, warning of unintended effects across the value chain. They note that producers already face high energy costs, exchange-rate volatility, elevated interest rates and weak consumer spending. Added taxes, they argue, risk raising production costs that are ultimately passed on to consumers, and could strain an industry already under pressure.
Who feels it most
Lower-income households may feel the impact of higher drink prices more sharply, in a market where sweetened beverages are popular and affordable treats. That tension sits at the heart of the debate: a tax designed to improve public health and revenue could also add to the cost of living for the very consumers it aims to influence. Striking that balance is the policy challenge.
How other countries approach it
Taxes on sugar-sweetened beverages have been adopted in many countries as a tool to curb consumption of sugary drinks linked to obesity, diabetes and related diseases. Evidence from some of these places suggests that well-designed taxes can reduce purchases of the most heavily sweetened products and, in some cases, encourage manufacturers to reformulate with less sugar. A common debate is whether to set the levy as a flat amount or as a percentage, and whether to tie it to sugar content so that the heaviest products attract the highest charge. Earmarking the revenue for health programmes is another approach used to build public support, linking the tax directly to services people value. Critics everywhere raise concerns about the burden on lower-income consumers and on manufacturers, echoing the arguments heard in Nigeria. The shift to a percentage-based structure is partly intended to keep the levy from being eroded by inflation, a problem that has blunted the existing fixed charge. As Nigeria refines its policy, the experience of other nations offers lessons on balancing public-health goals, revenue needs and the realities of a price-sensitive market.
With the Senate backing the change, attention turns to how the new structure is finalised and implemented. Viorah TV will continue to follow the sugar tax debate and its effect on prices.
