Introduction: A Structural, Not Cyclical, Deficit

Tanzania's budget deficit is not a temporary fiscal imbalance driven by short-term shocks. Rather, it reflects deep structural dynamics within the country's public finance system. Despite consistent improvements in revenue collection — particularly by the Tanzania Revenue Authority (TRA) — the fiscal gap persists at around 3–4% of GDP annually, signaling that the deficit is rooted more in expenditure rigidity, debt dynamics, and institutional fiscal design than in revenue underperformance alone.

This comprehensive analysis examines the paradox at the heart of Tanzania's fiscal challenge: TRA achieves 100.5% to 108.4% of its collection targets, yet the government budget remains structurally inadequate. Three interlocking forces explain this phenomenon — extensive expenditure obligations consuming 68.3% of the budget for recurrent costs, substantial debt servicing absorbing over 16% of revenues, and weak Local Government Authority (LGA) revenues failing to match the scale of economic activities in their jurisdictions.

📉

Narrow Tax Base

Tax-to-GDP at 12.9% vs. 16% SSA average. Every 1pp increase = TZS 2.7–3.0T extra revenue.

🔒

Rigid Recurrent Spending

47.2% of budget committed to wages + interest before a single service is delivered.

⛓

Debt Servicing Drain

TZS 7.8 trillion in annual debt service. For every TZS 6 collected, TZS 1 goes to creditors.

🏘

Weak LGA Revenue

185 LGAs collect only TZS 1.36T/yr, just 2.8% of the national budget, despite hosting 40–50% of GDP activity.

🏗

Ambitious Development Agenda

SGR, JNHPP, Vision 2050 commitments require sustained capital outlay beyond fiscal space.

🔍 Key Finding

Even with TRA collecting TZS 82.6 billion above target in H1 2024/25, Tanzania still faces a budget deficit of 3.4% of GDP — a TZS 1.68 trillion shortfall — demonstrating that revenue performance alone cannot bridge the gap created by structural expenditure pressures.

Historical Budget Deficit Trend: Tanzania 1991–2030

Budget Balance as % of GDP — Historical & Projected

Historically, Tanzania's fiscal balance has averaged approximately –3% to –5% of GDP over the past three decades, with peaks of widening deficits during periods of heavy infrastructure investment and external shocks. Early surpluses in the mid-1990s gave way to persistent deficits following liberalization, with the deepest trough in 2010 (–4.74%) following the global recession. Recent fiscal consolidation has narrowed the gap, but structural forces keep it above the EAC's 3% convergence criterion.

⚠ EAC Benchmark

The East African Community (EAC) sets a maximum fiscal deficit of 3% of GDP as a convergence criterion. Tanzania has exceeded this threshold in 2021/22, 2022/23, and 2024/25, reflecting the structural nature of the fiscal gap.

Revenue Performance: Strong but Structurally Insufficient

TRA Exceeds Targets — Yet the Fiscal Gap Persists

Over the past two fiscal years, revenue performance has improved significantly. The Tanzania Revenue Authority (TRA) exceeded annual targets by approximately 3–4 percent. Yet this achievement conceals a deeper paradox: the national revenue base itself remains structurally narrow relative to the size of government commitments.

⚡ The Core Paradox

Even in January 2025 — when TRA achieved 108.6% of its monthly target — total revenues could not cover expenditure of TZS 3,806B, and the annual deficit remained at 3.4% of GDP. The structural gap is expenditure-driven, not a revenue collection failure.

The Tax-to-GDP Structural Gap

The core structural issue lies in Tanzania's tax-to-GDP ratio, which remains at approximately 12–13 percent. This falls short of multiple key benchmarks:

Tax-to-GDP Ratio: Tanzania vs. Benchmarks

Tanzania's structural revenue gap relative to regional and global standards

Tanzania (Current) 12.9%

Sub-Saharan Africa Average ~16%

Minimum Efficiency Benchmark 15%

Long-term Fiscal Sustainability Target 18%

Tanzania TRA Target (2027) 15%

Note: Bar width scaled proportionally to 26.4% upper bound for display clarity.

📐 Revenue Gap Calculation

Nominal GDP (2026 est.) ≈ TZS 275 Trillion

Every +1pp in tax-to-GDP = TZS 2.7–3.0 Trillion in additional revenue

Current gap below 15% benchmark ≈ 2.1 percentage points

⟹ Structural revenue shortfall = TZS 5.7–6.3 Trillion annually

Therefore, even when TRA exceeds its internal targets, the national revenue base itself remains structurally narrow relative to the size of government commitments. Closing this gap requires formalizing the informal economy — estimated at 50–65% of GDP and outside the tax net — rather than merely improving compliance within the existing base.

Wage Bill % of Budget	32.5%	<35%	Near ceiling	⚠ Near limit

Recurrent Expenditure Rigidity

Non-Discretionary Spending Locks in the Fiscal Gap

A central structural driver of the deficit is the dominance of recurrent expenditure in the national budget. In FY2024/25, recurrent expenditure accounted for approximately 65–69% of total spending, leaving limited space for development investment or fiscal adjustment.

FY2024/25 Budget Composition — Where the Money Goes

Development Expenditure	9.44	31.3%	16.4	Policy-driven
TOTAL EXPENDITURE	30.19	100%	~55.0	—

⚡ Critical Finding

47.2% of the entire budget (wages TZS 9.83T + interest payments TZS 4.45T = TZS 14.28T) is committed to fixed obligations before any government services are delivered or development projects funded. This leaves only 52.8% for operations, social services, and development — creating constant fiscal pressure.

Table 5 — Mandatory & Committed Expenditure Items FY2024/25

Expenditure Type	Amount (TZS T)	Reason It's Mandatory
Wages & Salaries (32.5%)	9.83	Public sector employment; politically sensitive — not reducible short-term
Debt Servicing (14.7%)	4.45	Contractual obligations; defaulting has severe credit & reputation consequences
Development Budget Mandate (31.3%)	9.44	Government policy commits 30–40% to development for growth targets
Fee-free Education Policy	~3.0	Constitutional commitment; essential social service
Infrastructure (SGR, JNHPP)	~5.0	Vision 2025/2050 multi-year contracts already signed
Elections (2024/2025)	~1.0	Constitutional requirement — unavoidable

This means that nearly half of all government expenditure (wages + interest) is effectively non-discretionary. When fixed obligations consume nearly 47–50% of the budget before service delivery expansion or new development priorities are considered, fiscal flexibility becomes structurally constrained. Any increase in revenue tends to be absorbed by rising wage costs, inflation-indexed spending, or debt servicing adjustments.

📐 The Budget Equation — Why Revenue Success ≠ Fiscal Adequacy

Revenue Available: TZS 28.12 Trillion

minus Wages (9.83T) + Interest (4.45T) + Other Recurrent (6.47T)

= Remaining: TZS 7.37 Trillion

BUT required: Development (9.44T) + Elections + Social Programs = TZS 11+ Trillion

⟹ STRUCTURAL DEFICIT: TZS 3.63+ Trillion (3.4% of GDP)

Rising Debt Servicing Burden

How Borrowed Yesterday Crowds Out Tomorrow

Public debt dynamics represent one of the most acute structural pressures on Tanzania's fiscal position. As debt stock has grown to finance infrastructure and development programs, servicing obligations have expanded to the point where they now consume a significant and growing share of government revenue — creating a self-reinforcing constraint on fiscal space.

FY 2026/27 (proj.)	7.80	~16.7%	12.6%	↑ Rising

⛓ Crowding-Out Effect

High domestic borrowing — accounting for 60% of deficit financing — raises domestic interest rates and reduces private sector credit growth from 15% (2010s) to ~10% post-2020. Funds that could be allocated to education, health, or infrastructure are diverted to creditors. Even if revenues grow by 20–25% annually, debt service obligations grow proportionally, limiting net fiscal space creation.

External Debt Service (USD)	USD 1–2B/yr	USD ~1.5B	FX exposure risk

📐 Debt Service Impact Calculation

For every TZS 100 collected by TRA:

→ TZS 16 immediately goes to interest payments

→ Only TZS 84 available for wages, services, development

Annual interest (TZS 4.45T) vs. development spending (TZS 9.44T) = 47% ratio

⟹ Nearly half of all development investment is "cost" before any project begins

Structural Weakness in LGA Revenue Mobilization

Local Government Authorities Collect Only a Fraction of What Their Economies Generate

A further structural driver of the national budget deficit lies in fiscal centralization and weak own-source revenue at the Local Government Authority (LGA) level. Tanzania's 185 LGAs (districts and councils) generate own-source revenues far below the scale of local economic activities, creating a dependency on central government transfers that reinforces national fiscal pressure.

Root Causes of LGA Revenue Weakness

📋

Narrow Revenue Base

LGAs are restricted to licenses, permits, and market fees — unable to capture VAT, income tax, or corporate tax, all of which flow to TRA.

📅

Outdated By-Laws

Many LGAs still use 2012 bylaws with fees too low relative to current inflation. A market stall permit may still cost what it did a decade ago.

💻

No Digital Systems

Unlike TRA's EFD (Electronic Fiscal Devices), most LGAs use manual collection — creating leakage, fraud, and no audit trail.

🗳

Political Constraints

Locally elected officials face voter resistance to fee increases, creating political disincentives to improve revenue mobilization.

👥

Staff Capacity Gaps

Insufficient revenue officers across 185 LGAs cannot monitor all economic activities; internal controls remain weak per CAG findings.

⚖️

Structural Imbalance

LGAs are mandated to deliver primary education, health, local roads, and water — costs that far exceed their revenue capacity, forcing dependency on central grants.

Table 11 — LGA Fiscal Reality and National Budget Impact

LGA Fiscal Indicator	Value / Impact
LGA own-source revenue (annual)	TZS 1.36 trillion (2.8% of national budget)
LGA total budget (incl. central transfers)	TZS 15.8 trillion (48% of recurrent spending)
Central government grants to LGAs	TZS 4.66 trillion added pressure on national budget
LGA dependency on central transfers	80–90% of LGA budgets
Potential digital reform gains	+30% boost in LGA collections (World Bank est.)
Economic activities in LGA jurisdictions	Agriculture (26.5% GDP), trade, construction, services
Revenue realized from local economic activities	<5% of potential — only 20% of taxes realized

⚠ Structural Mismatch

Local Government Authorities preside over billions of shillings in economic transactions daily — agriculture, trade, construction, services — yet collect only TZS 1.36 trillion annually across all 185 LGAs. That is less than 5% of TRA's collection. This forces the central government to fund both national and local functions, adding TZS 4.66 trillion to the national fiscal burden and reinforcing the deficit.

Expansionary Development Commitments

Vision 2050 Ambitions vs. Available Fiscal Space

Tanzania has pursued an ambitious development agenda including the Standard Gauge Railway (SGR), Julius Nyerere Hydropower Project (JNHPP), strategic industrialization, and the long-term Vision 2050 goals. These commitments require sustained capital expenditure that consistently pushes total spending beyond what domestic revenues can support — a key structural contributor to the persistent deficit.

Table 12 — Major Development Commitments and Fiscal Impact

Standard Gauge Railway (SGR)	USD 7.6B+ total	Multi-year debt obligations; ~TZS 2–3T/yr	🔄 Ongoing

Vision 2050 Industrialization	Long-term	SEZ, EPZ, industrial parks — sustained capital outlay	🔄 Multi-decade

📌 Structural Tension

While GDP growth is projected at 6.3% real growth in 2026, and domestic revenue is expected to rise to TZS 46.7 trillion, grants are projected to decline by nearly 44.8% to just TZS 563.1 billion — increasing reliance on domestic resources and borrowing. Without structural reform, expansion risks pushing the deficit beyond the targeted 3% of GDP if growth assumptions or revenue projections underperform.

FY2026/27 Revenue vs. Expenditure — Three Scenarios

Base case vs. optimistic vs. stress scenario · TZS Trillion

⚠ Sustainability Verdict

The FY2026/27 expansion is conditionally sustainable if revenues hit targets and GDP growth sustains at 6.3%. However, a combination of declining grants (–44.8%), rising debt service (+13% YoY), and historical patterns of spending overruns creates meaningful risk of slippage above the 3% deficit target. The structural gap remains unless tax-to-GDP rises by at least 1–2 percentage points and LGA revenue mobilization is accelerated.

Conclusion & Policy Recommendations

Addressing the Root Causes — Not Just the Symptoms

A Structural, Not Cyclical, Deficit

Tanzania's budget deficit cannot be solved through revenue collection improvements alone. The paradox of TRA consistently exceeding targets while the budget remains inadequate reveals a fundamental mismatch: the country's ambitious development agenda, legacy debt obligations, and insufficient revenue mobilization at the local government level create a recurring fiscal gap of approximately TZS 3–7 trillion annually — equivalent to around 3% of GDP.

Five structural forces sustain this gap regardless of TRA's performance: (1) a tax base too narrow at 12.9% of GDP, (2) 47.2% of the budget locked in non-discretionary wages and interest before services begin, (3) rising debt service consuming 30–35% of revenues in peak quarters, (4) 185 LGAs collecting only 2.8% of the national budget despite hosting over 40% of GDP, and (5) multi-decade development commitments exceeding available fiscal space.

Policy Recommendations

💰

Revenue-Side Reforms

Accelerate tax-to-GDP ratio from 12.9% to 15% target by 2027 through broadening the base, not just improving compliance in the existing base.

Formalize the informal sector — estimated at 65% of the workforce and currently outside the tax net — through tiered presumptive tax systems and digital registration incentives.

Expand IDRAS (Integrated Domestic Revenue Administration System) nationwide to reduce leakage, improve compliance, and create a real-time fiscal monitoring framework.

Target tax-to-GDP of 18% as a long-term fiscal sustainability goal, which would generate an additional TZS 14–15 trillion annually at 2026 nominal GDP levels.

✂️

Expenditure-Side Reforms

Restructure domestic debt to reduce the interest burden from over 16% to below 10% of revenue, shifting to longer-tenor concessional instruments where possible.

Implement strict wage bill controls to prevent exceeding the 35% of budget ceiling — particularly as FY2026/27 proposes a further 15% wage bill increase.

Prioritize high-return development projects that generate future revenue (energy, ports, tourism infrastructure) over prestige projects with limited fiscal multipliers.

Cut non-essential recurrent expenditures by 10% through procurement rationalization, subsidy review, and operational efficiency gains.

🏘

Local Government Revenue Reforms

Expand LGA revenue sources beyond market fees and business licenses — introduce property tax systems, service fees aligned with economic activities, and tourism levies.

Update LGA bylaws across all 185 councils with realistic fee structures that reflect current inflation and economic values (many still use 2012 rates).

Implement digital revenue collection systems in all 185 LGAs — World Bank estimates this alone could boost LGA collections by 30%, adding TZS 400–500 billion annually.

Strengthen internal audit and control systems to prevent fraud and revenue leakage identified by the Controller and Auditor General (CAG) in successive annual reports.

📅

Medium-Term Fiscal Planning

Adopt a credible medium-term expenditure framework (MTEF) with budgets averaging TZS 68 trillion/year through 2028/29, anchored to realistic revenue projections rather than optimistic targets.

Maintain the EAC 3% deficit ceiling as a hard fiscal rule, with automatic expenditure adjustments triggered if revenue underperforms by more than 5%.

Focus on concessional debt for major projects to minimize borrowing costs — the current 1–3% rate on 25–40 year external loans versus 8–10% on domestic debt represents a significant fiscal advantage.

Build a fiscal stabilization reserve of at least 0.5% of GDP to buffer against climate shocks, commodity price swings, and other external vulnerabilities.

Recurrent Expenditure Rigidity	47.2% of budget non-discretionary	Wage bill below 35%; interest below 10% of revenue	+TZS 2–4T fiscal space released
Rising Debt Service	16%+ of revenue; TZS 7.8T FY2026/27	Debt restructuring; concessional focus; below 10% of revenue	Deficit narrows by 0.5–1.0% of GDP
Weak LGA Revenue	TZS 1.36T/yr (2.8% of budget)	Digital systems + bylaw updates → +30%	+TZS 400–500B; reduce central transfers
Excessive Development Commitments	Exceeds fiscal space annually	MTEF prioritization; high-return project focus	Deficit stabilized at 2.5–3.0% of GDP

✅ Final Assessment

Tanzania's budget deficit challenge is not a failure of revenue collection — TRA consistently exceeds targets and demonstrates strong institutional capacity. Rather, it reflects a fundamental mismatch between the country's ambitious development agenda, legacy debt obligations, and insufficient revenue mobilization at the local government level. Without structural reforms addressing all five drivers simultaneously, even perfect tax collection will not close the budget gap. The solution requires both expanding the revenue base and rationalizing expenditure priorities, while managing debt more sustainably — and this analysis provides the roadmap for how Tanzania can achieve fiscal sustainability by FY2028/29.
