This report brings together two complementary analytical streams: (1) an assessment of the immediate fuel price crisis and the tax relief options available to the Government of Tanzania; and (2) a structural analysis of how Tanzania's tax revenue has been allocated compared to global best practice — and what reforms are needed to prevent future vulnerability.

The analysis draws on EWURA fuel pricing data, Tanzania Ministry of Finance budget statements, the World Bank's 19th Tanzania Economic Update, IMF fiscal assessments, and OECD Revenue Statistics 2025, cross-referenced with case studies from Singapore, South Korea, Rwanda, Mauritius, Botswana, Germany, and the United States.

The key findings are stark: Tanzania is simultaneously under-taxing the private sector's potential (through a 30% CIT that deters investment), over-burdening the population through regressive taxes on essential commodities like fuel, and misallocating the revenue it does collect by prioritising recurrent government operations over the human capital and enabling-environment investments that would create a larger and more resilient tax base. The current fuel crisis is not merely a terms-of-trade shock — it is a stress test that has exposed the fragility of Tanzania's fiscal model.

The Strait of Hormuz, the 33-kilometre-wide passage between the Persian Gulf and the Gulf of Oman, is the single most strategically critical energy corridor in the world. Approximately 20.9 million barrels of oil — equivalent to 20% of global daily oil consumption — transit through Hormuz every day. In 2026, escalating regional tensions, threats to shipping, and increased insurance risk premiums have created the most severe Hormuz disruption in a decade, with Brent crude prices rising from approximately USD 73/barrel to USD 109–120/barrel — an increase of 49–64%.

For Tanzania, which imports 100% of its refined petroleum products (primarily through Dar es Salaam and Tanga ports), this external shock transmits directly and rapidly into domestic fuel prices, which are set by EWURA on a monthly basis using a formula incorporating international prices, freight costs, exchange rates, and domestic taxes and levies.

Tanzania's pump price is the product of an internationally-determined base cost — the landed cost of the petroleum product — plus a structured set of government taxes, levies, and regulatory fees applied by EWURA's pricing formula. Understanding this architecture is essential to identifying which levers are available to government, and what the trade-offs of each lever are.

Fuel is not merely a commodity — it is an input into virtually every sector of Tanzania's economy. When fuel prices rise sharply, the inflationary effect does not remain contained within the transport sector; it cascades through food production, manufacturing, construction, healthcare delivery, and education logistics.

The compounding timeline — in which each sector's price increases then feed into other sectors' input costs — means that the initial fuel price shock of TZS 900–1,000/litre (relative to pre-crisis levels) will, if unaddressed, translate into an economy-wide inflationary wave over the next 6–18 months.

In a crisis driven primarily by external forces — global oil market disruption, geopolitical risk in the Hormuz Strait, elevated global shipping costs — government's most powerful and immediately available tool is the adjustment of domestic taxes and levies on petroleum products. Unlike structural reforms that take years to implement, tax adjustments to fuel can be implemented within weeks, and their price effects are transmitted to consumers within days through EWURA's monthly pricing formula.

The critical design principles for such relief: it must be (1) temporary and time-bound with a clear sunset clause; (2) tied to a specific trigger — in this case, Brent crude price and/or EWURA's computed pre-tax landed cost; and (3) fiscally managed, with the government identifying offsetting measures or using existing fiscal space to absorb the short-term revenue impact.

The following scenarios model the expected pump price reduction under different policy configurations. All scenarios assume a base Brent crude price of USD 109–115/barrel and the current TZS exchange rate against the USD.

Tanzania Revenue Authority (TRA) classifies VAT on petroleum products as a core, non-negotiable revenue item. However, it is a policy choice, not an immutable constraint. Zambia provides the most directly relevant regional precedent: in 2023, faced with a similar fuel price crisis, Zambia's government zero-rated VAT on petroleum products — effectively removing 16% VAT from the pump price. The result was an immediate, visible price reduction that dampened inflationary pass-through to food and transport.

For Tanzania, full VAT removal would reduce the pump price by TZS 450–600/L — the single largest impact of any available lever. A partial measure — reducing VAT from 18% to 9% — would achieve approximately half this impact (TZS 220–330/L) at lower fiscal cost. Either approach is legally straightforward under Tanzania's VAT Act, 2014 — which already permits zero-rating of certain essential commodities through the Minister of Finance's regulatory powers — and would not require parliamentary legislation, only a subsidiary legislative instrument.

The fuel price crisis has revealed a deeper structural vulnerability in Tanzania's fiscal model. Tanzania's tax-to-GDP ratio of 13.1% (FY 2024/25) sits below the World Bank's critical 15% threshold — above which per capita GDP has been shown to be 7.5% larger. However, the core problem is not the level of taxation; it is what that revenue is spent on.

An analysis of Tanzania's budget allocation against global best practice reveals systematic under-investment in the enabling conditions that create long-term growth and fiscal resilience. The government is collecting a meaningful share of GDP in revenue — but deploying it in ways that do not build the structural resilience needed to weather external shocks like the Hormuz crisis.

Tanzania's fiscal structure has two critical weaknesses that the fuel price crisis has now placed under sharp relief. First, recurrent dominance: 58–70% of the annual budget is absorbed by recurrent expenditure — salaries, goods and services, and debt interest. This structurally crowds out the development spending that would build Tanzania's resilience and growth potential.

Second, human capital under-investment: education spending at 3.3% of GDP is 1.1 percentage points below the low-middle income country average of 4.4%, while healthcare spending at 1.2% of GDP is nearly half the LMIC average of 2.3%. Had Tanzania been investing tax revenue according to global best practice over the past decade — prioritising human capital, private sector enablement, and fiscal buffer-building — the country would today have a more productive workforce, a stronger diversified private sector, and a fiscal buffer from which short-term crisis relief could be financed.

The research evidence from seven countries — spanning two decades of data — converges on a consistent and clear conclusion: the countries that achieved the most dramatic development transformations did not use high taxation or state-led development as their primary strategy. They used government policy, enabling regulation, and targeted tax incentives to attract and channel private capital into national development priorities.

Singapore, with a tax-to-GDP ratio of 13.6% — nearly identical to Tanzania's 13.1% — has achieved a GDP per capita of USD 88,000 (PPP). The difference is not in how much tax Singapore collects, but in how it is spent and what enabling environment is created for private investment. South Korea's Five-Year Plans directed private firms through policy incentives — transforming the country from USD 103 per capita in 1962 to over USD 35,000 today without replacing private capital with state funding. Rwanda has attracted registered private investment growth of 515% in nine years by creating the most business-friendly environment in Africa.

The consistent pattern across all case studies is that government's optimal role in a developing economy is threefold: (1) regulate and create a stable, predictable, business-friendly environment; (2) invest tax revenue efficiently in human capital — education and health — that raises workforce productivity; and (3) use targeted, time-bound tax incentives strategically in priority sectors, not as permanent subsidies but as catalytic tools.

The following 10-point policy framework integrates both the immediate crisis response (fuel price relief) and the structural reforms needed to prevent future vulnerability. The framework is evidence-based, drawing on Tanzania's own fiscal data and the international case studies presented in this report, and is organised across three implementation time horizons.

Tanzania is at a critical juncture. The Strait of Hormuz disruption has created an acute fuel price crisis that is, in the absence of policy intervention, transmitting inflationary pressure across every sector of the economy. The Government of Tanzania has the tools to respond — specifically, the capacity to reduce the domestic tax burden on petroleum products to protect citizens and businesses from the full impact of an external shock that is not of Tanzania's making.

But this report argues that addressing the immediate crisis, while necessary, is not sufficient. The more important lesson from the current episode is structural: Tanzania's tax revenue model has not been building the fiscal resilience, private sector capacity, or human capital base that would make the economy less vulnerable to exactly these kinds of external shocks. A government that collects 13.1% of GDP in tax revenue and spends 58–70% of it on recurrent operations — while investing less in education and healthcare than the average low-middle income country — is not a government using tax revenue as an instrument of development. It is a government using tax revenue to sustain itself.

The global evidence is unambiguous: Singapore, South Korea, Rwanda, Mauritius, and Botswana did not build their development success on high taxation and state-led projects. They built it on smart governance — collecting what was needed, spending it on the enabling conditions for private sector growth, and making their countries the most attractive destinations for private capital in their regions.

Tanzania has the natural resources, geographic position, young population, and growing economy to compete for that capital. What it currently lacks is the policy clarity and fiscal discipline to do so. The 10-point framework in this report provides a data-backed, internationally-tested roadmap for the policy shift Tanzania needs.
