A comprehensive, data-driven assessment of Tanzania's recurrent versus development spending performance across FY2015/16–FY2025/26 — including structural diagnostics, reform scorecard, and critical implications for FYDP IV.
Drawing on official Ministry of Finance Budget Execution Reports, World Bank Economic Updates, and IMF Article IV consultations across ten fiscal years, TICGL's analysis reveals a structurally embedded gap between approved spending and actual expenditure — most acutely in development spending. FY2024/25 delivered a historic reversal.
⚠️ Critical Distinction: A gap exists between disbursement (Treasury releasing funds to MDAs) and absorption (MDAs actually spending those funds). Tanzania's absorption rate once funds are released is generally high (>95%). The primary bottleneck is disbursement — triggered by procurement readiness and financing availability. Targeting the wrong stage of the expenditure chain leads to wrong solutions.
Understanding what budget execution measures — and what it doesn't — is essential for diagnosing Tanzania's fiscal performance accurately.
Budget Execution Rate (BER) is defined as actual expenditure as a percentage of the approved budget or quarterly disbursement target. In Tanzania's fiscal framework, the overall execution rate is the weighted average of two fundamentally different spending categories.
Recurrent expenditure covers wages and salaries, interest and debt service payments, and operational transfers. These are largely mandatory and non-discretionary — they will be paid regardless of revenue performance.
Development expenditure covers capital investment in infrastructure, social services, and productive sectors — the projects that build Tanzania's long-run productive capacity and deliver visible outcomes for citizens.
Because recurrent spending constitutes 62–70% of the total budget, a stable recurrent rate (~96%) consistently masks severe development underperformance in the headline "overall execution" figure. Policymakers relying on headline figures alone will systematically misdiagnose Tanzania's fiscal health.
| Expenditure Category | Coverage | Share of Budget | 10-Yr Avg. Execution | Volatility | Policy Discretion |
|---|---|---|---|---|---|
| Recurrent | Wages, salaries, debt service, transfers | 62–70% | ~96% | Very Low | Limited — largely mandatory |
| Development | Capital investment, infrastructure, social services | 30–38% | ~73% | High (55%–100%) | High — discretionary and flexible |
| Overall (Weighted) | Combined average | 100% | ~82–87% | Medium | Dominated by recurrent weighting |

Ten years of budget execution performance reveals three distinct structural phases — from systematic underperformance through recovery to the historic 2024/25 breakthrough.
| Fiscal Year | Approved Budget (TZS Tn) | Recurrent Execution | Development Execution | Overall Execution | Dev. Budget (% of Total) | Key Driver / Note |
|---|---|---|---|---|---|---|
| 2015/16 | 29.5 | 96% | ~58% | ~82% | 38% | FYDP II launch; external financing gap; revenue miss |
| 2016/17 | 29.5 | 95% | ~55% | ~80% | 38% | Foreign loan procurement delays; domestic arrears build-up |
| 2017/18 | 31.7 | 96% | ~58% | ~81% | 38% | Dev. under-execution >40%; SGR began; domestic-financed rose |
| 2018/19 | 32.5 | 96% | ~65% | ~83% | 39% | Domestic dev. improved to 65%; foreign-financed avg. ~58% |
| 2019/20 | 33.1 | 95% | ~70% | ~85% | 38% | Pre-COVID: Domestic dev. 75%; Julius Nyerere HPP mobilized |
| 2020/21 | 36.0 | 96% | ~85% | ~90% | 37% | COVID fiscal pressure; Dev. avg. 67% (4-yr WB mean); uptick |
| 2021/22 | 38.5 | 97% | ~75% | ~86% | 37% | Post-COVID consolidation; SGR Phase 1 acceleration |
| 2022/23 | 40.5 | 97% | ~78% | ~87% | 37% | Dev. rising; JNHPP progress; tax-to-GDP 11.8% |
| 2023/24 | 44.9 | 97% | ~88% | ~93% | 38% | Strong revenue (TRA reform); NPMIS project tracking deployed |

A decade of data resolves into three structurally distinct performance eras, each driven by different forces.
The evidence strongly points to structural — not cyclical — causation. Tanzania's development execution gap persisted across boom years, a COVID shock, and post-COVID recovery.
A cyclical problem would resolve with economic recovery or revenue improvement. Tanzania's development execution gap persisted across 7% GDP growth years (2015–2019), the COVID shock (2020), post-COVID recovery (2021–2023), and only meaningfully improved after targeted institutional reforms. The World Bank (2023) attributed underperformance to "strategic planning, budget preparation, and procurement processes" — institutional, not cyclical, factors.
Development execution underperformance in Tanzania is predominantly a structural institutional failure — rooted in procurement system design, capacity deficits, foreign-financing architecture, and budget preparation quality — not a temporary revenue shock or cyclical economic factor.
| Structural Factor | Evidence / Mechanism | Policy / Reform Response |
|---|---|---|
| Procurement Bottlenecks | Long tendering cycles (6–18 months), land acquisition delays, weak project pipelines. Only ~TZS 1bn/yr budgeted for project preparation vs. TZS 680bn needed. | PPRA procurement reforms; NPMIS tracking; streamlined pre-qualification processes. |
| Foreign Financing Dependency | 20–30% of dev. budget is donor/loan-funded. Foreign-financed execution averaged only ~58% (2017/18–2020/21) vs. 75–85% domestically funded. | Diversify to domestic bonds, pension fund financing, PPP mechanisms under 2023 PPP Act. |
| MDA Absorption Capacity | MDAs face staffing gaps, cash-flow mismanagement, and technical capacity deficits. Non-salary goods/services chronically underspent. | Strengthen PFM at MDA level; frontline budget execution training; performance-linked disbursements. |
| Recurrent Budget Bias | 68–70% of budget is recurrent (wages, debt service). Rigid recurrent obligations crowd out development disbursements when revenues miss targets. | Revenue scaling: tax-to-GDP from 10% (2004) to 13.1% (2024/25) creates more predictable development funding. |
| Domestic Arrears & Cash Management | Estimated arrears stock exceeded 3% of GDP by 2017/18. Payment arrears delayed contractor performance and demotivated project execution. | Arrears clearance programme (~TZS 1tn/yr); stricter commitment controls; IFMS upgrade. |
| Budget Preparation Quality | Overambitious development estimates set execution rates up to fail. Insufficient linkage between budget planning and project readiness. | FYDP IV integrated planning frameworks; sector-level project preparation financing (TZS 680bn target). |

The aggregate development execution figure masks a critical internal divergence that explains the bulk of Tanzania's structural execution problem.
Tanzania's development budget has two distinct financing streams with dramatically different execution profiles. Foreign-financed project execution depends on procurement compliance with partner rules (World Bank, AfDB, JICA), satisfaction of disbursement conditions, and project implementation milestones — factors largely outside Treasury's direct control.
The World Bank Senior Economist Emmanuel Mungunasi specifically identified "delays in contracting non-concessional loans" and "delays in project preparation and implementation" as direct causes of foreign-financed under-disbursement. The aggregate 2024/25 result — 74% foreign-financed vs. 109% domestic — confirms this split remains active even as the headline figure reached 100%.
| Financing Stream | Typical Share of Dev. Budget | Avg. Execution (2017/18–2023/24) | FY2024/25 Execution | Primary Bottleneck |
|---|---|---|---|---|
| Domestically Financed | 70–80% | ~72–85% | 109% | Cash flow management; TRA revenue gaps mid-year |
| Foreign-Financed (Loans/Grants) | 20–30% | ~55–60% | 74% | Procurement compliance, disbursement conditions, project preparation |
| Combined (Weighted) | 100% | ~73% | 100% | Structural: procurement + financing architecture |

Even Tanzania's historic 100% development execution in FY2024/25 was achieved through exceptional domestic execution (109%) compensating for still-weak foreign-financed execution (74%). If domestic revenue growth slows under FYDP IV, this structural safety net disappears — and the foreign financing gap becomes fully exposed in headline figures.
A structured scorecard of the reforms driving Tanzania's improved execution performance — and those still needed.
| Reform Initiative | Expected Impact | Status | Execution Link |
|---|---|---|---|
| NPMIS — National Project Management Information System | Real-time project tracking; early warning on stalled contracts | Active (2023–) | Dev. execution 88%→100% (2023/24→2024/25) |
| TRA Digital Tax Systems (EFD, mobile money) | Tax-to-GDP growth to 13.1%; more predictable revenue = stable dev. disbursements | Active | Revenue predictability ↑ dev. execution stability |
| PPP Act 2023 Amendments | Private capital mobilisation for FYDP IV; off-balance sheet delivery | Active | Reduces pressure on public development budget |
| PPRC Arrears Clearance Programme | Clears contractor arrears; restores private sector confidence in government contracts | Ongoing (~TZS 1tn/yr) | Reduces execution drag from contractor stoppages |
| SOE Restructuring (TEMESA, ATCL) | Reduces fiscal transfers to loss-making SOEs; frees recurrent budget space | Ongoing | Recurrent execution more stable |
| FYDP IV Project Preparation Budget | Addresses pipeline gap (target TZS 680bn); pre-identifies bankable projects | Proposed / Partially funded | Critical for sustaining 90%+ dev. execution post-2025 |
Table 4: Budget Execution Reform Scorecard. Sources: MoF; World Bank; TICGL Analysis.
Tanzania's tax-to-GDP ratio rose from 10% in 2004/05 → 11.8% in 2022/23 → 13.1% in FY2024/25 (highest ever recorded). This matters directly for execution: mid-year budget revisions forced by revenue shortfalls have historically been the primary mechanism through which development execution rates collapse. The 2026/27 budget targets 26.5% tax revenue growth — historically unprecedented. A miss would re-activate the revenue-shortfall execution spiral at the critical FYDP IV launch year.
Tanzania's Fourth Five-Year Development Plan (2026/27–2030/31) requires TZS 477 trillion in total financing — and budget execution performance is the foundational credibility condition for mobilising 70% of that from the private sector.
🎯 FYDP IV Execution Imperative: Sustained 90%+ development execution over FY2026/27–2030/31 is not merely a fiscal performance metric — it is the foundational credibility condition for the TZS 334 trillion private capital mobilisation target. If public development execution remains below 80%, investor confidence in government-backed project timelines collapses, PPP bankability evaporates, and the private capital target becomes unreachable. Budget execution is macroeconomic signalling.
| Risk Factor | Description | Probability | FYDP IV Implication |
|---|---|---|---|
| Revenue Shortfall Risk | Tax revenue growth target of 26.5% for 2026/27 is historically high. Historical achievement: 89.6% of targets. | HIGH | Compressed development disbursements; PPP reliance increases |
| Foreign Financing Under-disbursement | Foreign development execution historically ~58%; donor alignment and procurement rules create persistent lags. | MEDIUM-HIGH | FYDP IV foreign-funded projects risk slippage without pipeline reform |
| MDA Capacity Ceiling | Even with funds released, some MDAs struggle to absorb. Staffing/technical gaps persistent since 2016. | MEDIUM | Spending efficiency may plateau without targeted capacity building |
| Debt Service Crowding | Interest payments rising; external debt 71.3% of total. Currency depreciation raises TZS obligations. | MEDIUM | Recurrent obligations may crowd out development space in FY2027+ |
| Project Preparation Gap | Only ~TZS 1bn/yr allocated for project prep vs. TZS 680bn needed. Thin pipeline = execution gaps. | HIGH | FYDP IV 70% private sector target impossible without bankable project pipeline |

TICGL's data-driven synthesis and six priority recommendations for sustaining Tanzania's 2024/25 execution breakthrough into FYDP IV.
| # | Conclusion | Confidence Level |
|---|---|---|
| 1 | Development budget execution in Tanzania has been a structural problem for over a decade — averaging ~73% over FY2015/16–2023/24 — driven primarily by procurement bottlenecks, foreign-financing absorption failures, MDA capacity gaps, and budget optimism bias, not purely by revenue shocks. | High — Multi-source |
| 2 | Recurrent execution has been consistently strong (~96%) throughout, reflecting mandatory spending dominance and protecting salaries and debt service at the expense of development disbursements when revenues miss. | High — Confirmed |
| 3 | FY2024/25 represents a genuine structural breakthrough: 100% development execution — the first in at least a decade — driven by NPMIS deployment, TRA revenue improvement, and SGR/JNHPP discipline. This is not a one-year statistical accident. | High — Confirmed |
| 4 | The foreign-financed execution gap (74% in 2024/25 vs. 109% domestically) remains a structural vulnerability requiring pipeline preparation investment — it was not resolved by the 2024/25 breakthrough. | Medium-High |
| 5 | Q1 FY2025/26 at 108% overall execution is a positive leading indicator, though election-cycle front-loading partially inflates this figure. The sustainability test comes in Q3–Q4 FY2025/26. | Medium |
