Chapter 1

Revenue Mobilization

Bangladesh's revenue mobilization failure is structural, not cyclical. The tax-to-GDP ratio was 8.98% in 1990 and 8.34% in 2024, a span of thirty-four years in which real GDP grew roughly twelvefold (Source: IMF). The National Board of Revenue (NBR) collected BDT 275,800 crore in FY2024, with VAT contributing 39.0% of that total and customs duties adding another 11.8% (Source: NBR Annual Report FY2024).

NBR Revenue Composition

NBR revenue grew from BDT 51,136 crore in FY2010 to BDT 275,800 crore in FY2024, a 5.4x increase. Income tax rose from 23.1% to 38.1% of total revenue, while customs fell from 19.2% to 11.8%, reflecting tariff rationalization and a slowly broadening domestic base. (Source: NBR Annual Reports FY2010-FY2024.)

VAT Efficiency Decline

VAT C-efficiency (actual VAT as a share of what a perfectly enforced VAT on observed consumption would yield) peaked at 18.9% in FY2012, fell to 12.8% in FY2022, and recovered partially to 14.5% in FY2024. A VAT system that became less efficient every year for a decade is not a tax system with a compliance problem; it is a policy problem. Returning C-efficiency to 18.9% on current consumption would add approximately 0.8 percentage points of GDP. (Source: NBR; BDPolicyLab computation.)

Peer Comparison and Tax Gap

Among available peer observations, Bangladesh ranks near the bottom in tax revenue as a share of GDP. Thailand collected 15.3% in 2024, Indonesia 11.1% (most recent observation), and Vietnam approximately 16 to 19 percent depending on the year. The tax gap relative to the peer median of 15% implies $31 billion in forgone annual revenue at 2021 GDP. (Source: World Bank WDI; IMF.)

Tax Buoyancy

Tax buoyancy (elasticity of tax revenue with respect to GDP) is 1.05 over the full sample, indicating the system is marginally elastic (revenue growing faster than GDP). Rolling 5-year estimates show significant variation, reflecting uneven policy and compliance effects. At 1.0, a flat ratio cannot be substantially reformed through economic growth alone; explicit base-broadening is required. (Source: BDPolicyLab rolling OLS on IMF/WB data.)

Chapter close: The revenue trajectory is not a temporary cyclical dip. It is a structural equilibrium that thirty-four years of government policy has permitted to persist. LDC graduation removes the buffer that allowed this equilibrium to be fiscally viable.

Chapter 2

Expenditure Analysis

Bangladesh's budget allocation in FY2024 shows education at 19.4% of total budget, health at 9.1%, defense at 9.7%, and interest payments at 20.8%. Interest payments have overtaken education as the single largest line item, driven by rising domestic debt costs and megaproject external borrowing. (Source: Ministry of Finance Budget in Brief FY2024.)

Annual Development Programme

The Annual Development Programme (ADP) grew from BDT 30,500 crore in FY2010 to BDT 277,600 crore in FY2024, a 9.1x expansion. Execution, however, ran at 80.8% in FY2024, implying BDT 53,299 crore in unspent allocation. Procurement delays, land acquisition bottlenecks, and capacity constraints in implementing agencies are the recurring causes. (Source: IMED ADP Progress Report FY2024.)

Subsidy Burden

Total subsidies reached BDT 69,500 crore in FY2024, with energy subsidies at 44.9% of the total. The energy subsidy surge in FY2022-23 (BDT 60,000 crore, energy share 48.0%) was driven by global fuel price shocks and crowded out development spending. (Source: Ministry of Finance.)

Interest Burden and Crowding Out

Interest payments consumed 34.3% of NBR revenue in FY2024, up from 28.9% in FY2015. This ratio has risen because both domestic borrowing costs and the external debt stock have grown faster than revenue. Every additional taka absorbed by interest service is a taka unavailable for education, health, or infrastructure. (Source: Ministry of Finance; NBR.)

Chapter close: Bangladesh's expenditure mix is structurally compressed by low revenue: interest payments now exceed 20% of the budget, leaving less than 10% for health and 8% for development investment after salaries. The Tarique Rahman government's FY27 budget will face this constraint directly.

Chapter 3

Fiscal Balance and Sustainability

The fiscal deficit has held in the 3-5% of GDP range for most of the past decade, with the latest reading at -3.9% of GDP (2026). While relatively contained by South Asian standards, the low revenue base means even a modest deficit requires substantial financing, and the composition of that financing has shifted toward more expensive instruments. (Source: IMF Article IV 2025.)

Primary Balance

The primary balance (fiscal balance excluding interest) stands at -2.0% of GDP in 2026, indicating a primary deficit, meaning even excluding interest payments, spending exceeds revenue. A primary deficit means the government is borrowing not just for investment but to cover current operations net of interest. (Source: IMF; BDPolicyLab computation.)

Structural Balance

Decomposing the fiscal balance into structural and cyclical components isolates the underlying fiscal stance from the business cycle. The structural balance uses HP-filtered potential GDP with a budget elasticity of 0.4. In 2024, the structural deficit (-4.02% GDP) is narrower than the headline deficit (-3.7% GDP), implying some cyclical deterioration layered on the structural position. (Source: BDPolicyLab structural balance estimation.)

Debt Sustainability Analysis

The IMF-style debt sustainability analysis projects three trajectories from the 2024 starting point of 40.2% of GDP. Under the baseline (average growth 5.5% with current policies), debt declines to 10.8% of GDP by 2034. The adverse scenario (growth shock, higher interest rates) slows consolidation to 26.2%. The reform scenario (revenue mobilization plus expenditure efficiency) produces -5.6% by 2034. (Source: BDPolicyLab DSA following IMF LIC DSA framework.)

Fiscal Space

The fiscal space model (Ostry et al. 2010, 2013) estimates the gap between current debt (40.2% of GDP) and a country-specific debt limit. With a fiscal reaction function coefficient of -0.713, the model suggests limited evidence of a binding debt ceiling at current debt levels, though the risk profile tightens materially above 50% of GDP. (Source: BDPolicyLab; Ostry et al. 2010, 2013.)

Chapter close: The fiscal position is not in acute crisis, but the structural deficit (-4.02% of GDP in 2024) and rising interest burden together narrow the room for expansionary responses to shocks. Revenue mobilization is the least disruptive path to creating that room.

Chapter 4

Public Debt Architecture

Public debt stands at 40.2% of GDP (2026, IMF), moderate by international standards but on a structurally rising path. The more significant shift is qualitative: the traditional reliance on concessional multilateral lending is giving way to a more expensive mix of commercial borrowing and domestic market instruments. This matters because the cost of servicing a given debt level is rising even as the headline ratio remains contained.

Debt Composition

The external debt portfolio in FY2024 is dominated by multilateral creditors (55.3%), followed by bilateral (27.6%) and commercial sources (17.2%). Commercial borrowing carries higher interest rates and shorter maturities than IDA or bilateral concessional terms, raising debt service costs even without a rise in the headline debt ratio. (Source: ERD Annual Report FY2024; Bangladesh Bank.)

Megaproject Debt

Bangladesh has committed $19.2 billion in megaproject loans covering power generation, transport, and port infrastructure. These loans concentrate debt service in the late 2020s and early 2030s, creating a repayment hump that coincides directly with the post-LDC loss of concessional refinancing options. (Source: ERD project financing records.)

Foreign Exchange Reserves and Import Cover

Foreign exchange reserves fell from a peak of $46.4 billion to $24.4 billion in FY2024, reducing import cover to 3.2 months. The IMF's 3-month adequacy threshold is now only 0.2 months away. Reserve erosion limits Bangladesh Bank's ability to manage exchange rate volatility and service external debt obligations. (Source: Bangladesh Bank; IMF.)

Chapter close: At 40.2% of GDP, the headline debt ratio is manageable. The structural shift toward commercial debt and the megaproject repayment hump in the late 2020s represent the real risk, especially if revenue reform is delayed and domestic borrowing must fill the gap.

Chapter 5

LDC Graduation and Fiscal Reform

On November 24, 2026, Bangladesh graduates from UN Least Developed Country status. The EU's Everything But Arms preference, IDA concessional financing, and TRIPS pharmaceutical waivers all expire on staggered post-graduation timetables. The fiscal channel is direct: trade taxes represent 22.3% of NBR revenue (FY2024, NBR), and concessional borrowing costs will rise materially. The Tarique Rahman BNP government, sworn in February 17, 2026, faces this deadline in its first full budget cycle.

Trade taxes (customs and supplementary duty) totalled BDT 32,450 crore plus BDT 29,100 crore in FY2024, or 22.3% of total NBR collection. The mid-range estimate for revenue at risk from preference erosion is BDT 11,079 crore, representing 4.0% of total NBR revenue. (Source: BDPolicyLab computation on NBR FY2024 data.)

Revenue Reform Scenarios

Closing the fiscal gap requires raising the tax-to-GDP ratio from 8.5% toward regional peers. Three reform scenarios are modelled: modest reform lifts the ratio to 11% (additional revenue $11.3 billion per year), moderate reform to 13% ($20.3 billion), and ambitious reform to 15% ($29.3 billion). Even the ambitious scenario leaves Bangladesh below Thailand's 2024 level. (Source: BDPolicyLab reform scenario modelling.)

Reform Roadmap

Phase 1: Foundation (2024-2026)

• Universal TIN registration and enforcement
• VAT automation and e-filing expansion
• Customs modernization (single window, risk-based inspection)
• Tax expenditure review and rationalization

Phase 2: Broadening (2026-2028)

• Property tax reform at local government level
• Capital gains tax on real estate transactions
• Digital economy taxation framework
• Reduction of tax exemptions (current ~3% of GDP in tax expenditure)

Phase 3: Deepening (2028-2030)

• Progressive income tax with expanded brackets
• Environmental taxation (carbon, pollution)
• Financial transaction taxes
• Full integration of informal economy

Spending Gaps vs SDG Benchmarks

Across five key sectors, the total spending gap relative to international SDG benchmarks is 10.1% of GDP ($45.5 billion). This directly quantifies the fiscal effort required to move Bangladesh to benchmark spending levels:

• Education: 2.0% vs 4.0% target (UNESCO), gap: 2.0% GDP ($9.0B)
• Health: 0.9% vs 3.0% target (WHO/Lancet), gap: 2.1% GDP ($9.5B)
• Social Protection: 1.7% vs 4.0% target (ILO), gap: 2.3% GDP ($10.4B)
• Infrastructure: 2.5% vs 5.0% target (ADB), gap: 2.5% GDP ($11.3B)
• Climate Adaptation: 0.8% vs 2.0% target (IPCC), gap: 1.2% GDP ($5.4B)

Chapter close: The November 2026 graduation date is fixed. The three highest-yield reforms, property tax modernisation, VAT base recovery, and exemption sunset, are individually well-understood. Their combined 3.1-percentage-point yield by 2030 represents the fastest path to closing the gap without deficit expansion.

Analytical Methods and Cross-Cutting Findings

Revenue Effort Index

The stochastic frontier revenue effort index compares actual tax collection against the level predicted by structural factors (GDP per capita, agricultural share, trade openness). Bangladesh's effort index of 1.024 means it collects marginally more than predicted by its structural characteristics. Despite collecting above its structural prediction, the absolute level remains far below regional peers. (Source: BDPolicyLab stochastic frontier estimation.)

Fiscal Multiplier

The estimated fiscal multiplier for Bangladesh is 0.49: a 1 percentage point increase in government spending as a share of GDP is associated with a 0.49 percentage point change in GDP growth. This is above the South Asian average of 0.4, suggesting fiscal expansion has above-average growth impact, making quality public investment particularly valuable. (Source: BDPolicyLab VAR estimation.)

Structural Balance Assessment

The structural balance (adjusted for cyclical effects via HP-filtered potential GDP) stands at -2.35% of GDP (2024). The 5-year average structural balance is -4.09%. The structural deficit is narrower than the headline figure, indicating some cyclical deterioration in the current year that will partially self-correct. (Source: BDPolicyLab.)

Policy Implications

Six Strategic Priorities

Bangladesh's fiscal position is not in crisis, but it is on an unsustainable trajectory absent deliberate reform. The combination of a 8.3% tax-to-GDP ratio, a 34.3% interest-to-revenue ratio, 3.2 months of import cover, and confirmed LDC graduation in November 2026 defines a narrow action window. Six priorities emerge from this analysis:

1. Revenue mobilization as the overriding priority. Raising tax-to-GDP by 4 to 6 percentage points over a decade through VAT base broadening (target: C-efficiency back to 18.9%), property tax modernisation, TIN enforcement, and a five-year sunset programme on tax expenditures estimated at ~3% of GDP. The FY27 budget, the Tarique Rahman government's first full-year budget, is the earliest credible legislative vehicle.
2. Expenditure efficiency and reallocation. Improving ADP execution from 80.8% toward 90%+, rationalising energy subsidies toward targeted transfers, and protecting health and education from further crowding out by interest payments. Every taka of better ADP execution is a taka of capital formation that does not require new borrowing.
3. Debt portfolio management. Actively managing the shift from concessional (55.3% multilateral, FY2024) to commercial debt (17.2%), extending maturities where possible, and smoothing the megaproject repayment hump of the late 2020s before graduation forecloses IDA refinancing.
4. LDC graduation fiscal preparedness. Replacing trade-dependent revenue (currently 22.3% of NBR collection) with domestic taxation before EBA preferences expire. The 2026 to 2029 transition window is the only period when both systems are simultaneously available as bridging revenue.
5. Reserve rebuilding. Coordinating fiscal consolidation with monetary policy to rebuild FX reserves above the 3-month IMF threshold. At 3.2 months, the margin is thin. External debt service capacity depends on adequate reserve buffers.
6. Institutional capacity building. Strengthening NBR's digital infrastructure, expanding the TIN net (fewer than 4 million active filers in a 175-million population), building capacity for evidence-based fiscal policy, and improving budget transparency. The data exists; the administrative follow-through does not.
