Fiscal Policy

The State of Bangladesh Public Finance

Bottom Line

Bangladesh's fiscal position is structurally broken at the revenue side. A $450 billion economy growing at 4.2% collects 7.64% of GDP in taxes, critically low and 7.4 pp below the 15% developing-country median. Only 1.2 million people pay any tax in a population of 173.6 million, yielding a taxpayer-to-population ratio of 0.69%. Total government revenue of 9.54% of GDP against expenditure of 8.32% of GDP produces a fiscal surplus of 1.21% of GDP. Public debt at 40% of GDP is currently sustainable, but rising megaproject debt service and imminent LDC graduation will sharply narrow fiscal space. The base case requires revenue reform within the next three years. The risk case, where reform stalls, leads to a structural development trap and eroding creditworthiness.

Revenue: A Critically Low Tax Base

Bangladesh's 7.64% tax-to-GDP ratio stands 7.4 pp below the developing-country median of 15%. The gap is not a rounding error: it represents $33.1 billion in foregone annual revenue. Peer benchmarks make the structural underperformance concrete. India, despite federal complexity and a comparably large informal sector, collects around 17% of GDP in combined central and state taxes. Vietnam collects approximately 18%. Even Sri Lanka, post-restructuring, has rebuilt to roughly 11%. Bangladesh has not crossed 10% since the mid-2000s.

Tax revenue improved by 0.64 pp year-on-year, a positive but insufficient increment against a 7.4pp gap.

Tax composition exposes three structural weaknesses. VAT at 38% of total tax revenue is the largest instrument but operates at a C-efficiency ratio below 40%, compared to 55-65% in Vietnam and Thailand. The 2012 VAT Act, designed for a uniform 15% rate with full input credit chains, was implemented in 2019 in a diluted form with multiple reduced rates, extensive exemptions, and truncated credit mechanisms. Income tax at 32% of total is constrained by the narrow tax base analyzed below. Customs duties at 22% face structural decline as post-LDC trade liberalization deepens, putting an estimated $7.6 billion in annual customs revenue at risk. Non-tax revenue at 2.0% of GDP, drawn from SOE dividends, spectrum fees, and administrative charges, provides a thin cushion that cannot substitute for structural reform.

The Tax Base Funnel: 10.8M TINs to 1.2M Payers

The tax base crisis reduces to a single funnel. Bangladesh has 10.8 million registered TIN holders. Of these, 4.4 million file returns (41% of TIN holders). Of filers, only 1.2 million actually pay tax (27% of filers). The rest show zero liability through exemptions, blanket deductions, or underreporting that the National Board of Revenue (NBR) cannot detect without cross-referenced data infrastructure.

Three causes drive this outcome. First, the informal economy, estimated at 30-40% of GDP, operates almost entirely outside the tax net. Formalizing these activities requires not higher enforcement intensity but lower compliance cost: simplified presumptive tax regimes, digital payment mandates, and TIN-NID linkage that makes registration consequential. Second, NBR institutional capacity is inadequate: IT systems cannot cross-reference income, asset, and spending data; audit staff-to-taxpayer ratios are far below comparator countries; and governance constraints erode both collection efficiency and public trust. The NBR processes many returns manually in district offices, in sharp contrast to India's GSTN platform handling 10 million filings per month. Third, a dense web of tax holidays, preferential rates, and sector exemptions, many dating to early RMG development incentives, erodes the formal-economy base. Revenue foregone through concessions is estimated at 2-3% of GDP annually.

Expenditure: Binding Revenue Constraint, Not Austerity

Government expenditure of 8.32% of GDP (+0.18 pp change) is low not by fiscal-consolidation design but because inadequate revenue imposes a hard ceiling. Roughly 5.6% of GDP goes to current expenditure; only 2.7% of GDP remains for the Annual Development Programme (ADP). ADP utilization of 68% means Bangladesh does not even fully spend its constrained development envelope, a signal of procurement delays, land acquisition bottlenecks, and weak project management rather than adequate public investment.

Within the current budget, three items dominate and constrain flexibility. Interest payments at 2.5% of GDP represent a first charge on revenue that will rise as megaproject grace periods expire. Energy and agricultural subsidies at 1.5% of GDP are regressive (upper quintiles consume more electricity and fuel) yet politically durable. Together, interest and subsidies absorb resources that cannot reach health, education, or climate adaptation.

Sectoral allocation illustrates the squeeze. Health at 0.7% of GDP forces 65-70% of health spending onto households as out-of-pocket payments, the primary driver of medical-poverty traps. Education at 2.0% of GDP falls well below the UNESCO benchmark of 4-6%. Social protection at 2.5% of GDP covers a fraction of the vulnerable population. Defense at 1.2% of GDP is modest compared with regional peers (India 2.4%, Pakistan 3.5%) but still competes for constrained fiscal space.

Infrastructure megaprojects anchor the development budget: Padma Bridge ($3.5 billion self-financed), Dhaka metro rail ($2.8 billion JICA-funded), Rooppur nuclear plant ($12.65 billion on Russian sovereign credit), and Payra deep-sea port. Each project is individually defensible on economic return grounds; their aggregate recurrent cost implications and debt service schedules have not been adequately integrated into medium-term fiscal frameworks. The structural tension is stark: Bangladesh is building 21st-century infrastructure on a 7.6% tax base.

Fiscal Balance and Debt Sustainability

With revenue at 7.64% of GDP, roughly one-third of all government spending is financed by borrowing. This is not a short-term shock; it is a decade-long structural pattern.

Public debt at approximately 40% of GDP (18% domestic, debt-to-GNI at 22.3%) sits well below the 60% benchmark for developing countries. Bangladesh compares favorably with India (83%), pre-restructuring Sri Lanka (128%), and Pakistan (75%). But trajectory matters more than level. Domestic debt expansion through treasury bills and bonds creates a crowding-out dynamic in Bangladesh's shallow financial markets: government securities absorb banking liquidity, constraining private credit growth, dampening investment, and compressing the tax revenue that growth would generate.

External medium/long-term debt of $80 billion has grown rapidly through megaproject disbursements. The Rooppur loan alone will generate approximately $1 billion in annual debt service once the grace period expires. Combined with other megaproject obligations, external debt service could double within five years, absorbing a growing share of export earnings precisely when LDC graduation tightens access to concessional finance and RMG export preferences narrow.

Sri Lanka's 2022 default is the cautionary reference: a product of tax-to-GDP falling from 14% to 8%, persistent deficits financed by non-concessional borrowing, and a concentrated external shock. Bangladesh shares the revenue-thinness and borrowing-dependency. The difference is that Bangladesh still has the growth trajectory and policy space to act. That window is finite.

Two Scenarios Through 2030

Base case (reform advances): Tax-to-GDP reaches 10% by FY2027 via NBR digitization, TIN-NID integration, and VAT enforcement, generating $10.6 billion in additional annual revenue. Subsidy rationalization redirects 0.7-1.0% of GDP toward health and education. Debt service is absorbed without crowding out private investment. LDC graduation is managed through a pre-built domestic revenue base and diversified export markets. Fiscal consolidation path is credible.

Risk case (reform stalls): Tax-to-GDP remains near 7.6%. Megaproject debt service rises by $2-3 billion annually. LDC customs revenue erosion ($7.6 billion per year) compounds the shortfall. Domestic borrowing crowds out private credit. Bangladesh avoids acute crisis but enters a structural development trap: the state cannot fund the infrastructure, healthcare, education, or climate adaptation a middle-income transition requires. Sovereign risk perception rises as concessional finance access narrows post-graduation.

Three Priority Recommendations

1. Digitize NBR and close the TIN-payer funnel. Mandate e-filing for all 10.8 million TIN holders, integrate NID and bank account data for income cross-referencing, and deploy e-invoicing mandates for all VAT-registered firms. The compliance gap between 10.8M TIN holders and 1.2M actual payers is an administrative failure, not an economic one. Closing the funnel to 50% actual payment without raising rates would add more than $10.6 billion annually. Target 10% tax-to-GDP by FY2027 as a binding performance benchmark for NBR management.

2. Replace blanket subsidies with targeted cash transfers. Introduce automatic fuel price adjustment mechanisms tied to international benchmarks and redirect subsidy savings (estimated 0.7-1.0% of GDP) to: health spending from 0.7% toward 1.5% of GDP, education from 2.0% toward 3% of GDP, and cash transfers to the bottom 30% via mobile financial services. Fiscal impact is near-neutral; development impact is transformative. This reallocation also reduces the contingent liability risk from commodity-price-driven subsidy overruns of $1-2 billion per shock event.

3. Activate local government revenue before LDC graduation. Commission municipal property tax reform, urban service charges, and land transfer fees to generate 0.3-0.5% of GDP in sub-national revenue. Local revenue reduces central budget pressure, improves service delivery accountability, and diversifies the revenue base away from customs duties facing LDC graduation erosion. Legislation authorizing local property registries and valuation updates must precede graduation, not follow it.

Bangladesh's 4.2% growth rate and $450 billion economy provide a rare window of reform from relative strength. The combination of 7.6% tax-to-GDP, 1.2 million actual taxpayers, and $12.65 billion in nuclear power debt approaching repayment is a fiscal equation that growth alone cannot solve. Revenue reform is the single highest-leverage action available to Dhaka before the graduation clock runs out.
