Abstract: The Tax Burden on Tanzania's SMEs
Small and Medium Enterprises (SMEs) are Tanzania's economic backbone — yet the country's tax architecture is systematically undermining their survival. This TICGL research study, drawing on survey data from 250 SMEs across five regions, quantifies the damage and maps a path toward reform.
Without urgent tax reforms, Tanzania risks entrenching a two-tier economy: a shrinking formal sector crushed by compliance costs, and a vast informal sector that generates employment but fails to contribute to the tax base needed for national development.
Introduction: The Role of SMEs in Tanzania's Economy
1.1 Background of SMEs in Tanzania
Small and Medium Enterprises (SMEs) play a crucial role in Tanzania's economy, contributing significantly to employment, GDP, and poverty reduction. According to the Tanzania National Bureau of Statistics (NBS), SMEs make up over 95% of all businesses in the country and employ approximately 5 to 6 million people, representing nearly 35% of the workforce.
SMEs operate across diverse sectors — agriculture, trade, manufacturing, services, and construction. Despite their importance, they face numerous challenges including limited access to finance, regulatory constraints, and an unfavorable tax environment. The Tanzania Development Vision 2025 recognizes SMEs as a key driver of economic growth but highlights taxation as one of the major barriers to their sustainability.
1.2 Importance of SMEs in Economic Growth
Contribution to GDP
SMEs contribute approximately 35% of Tanzania's GDP. This share could increase significantly if the business environment, including tax policy, is improved to encourage growth and formalization.
Employment Creation
SMEs absorb a large portion of the labor force, particularly in the informal sector, providing jobs to about 72% of Tanzania's workforce, helping reduce poverty and promote economic inclusion.
Innovation & Entrepreneurship
SMEs promote innovation by introducing new products and services. Many startups in Tanzania emerge from SME entrepreneurs who find creative ways to meet local market demands and solve community problems.
Revenue for Government
SMEs contribute to government revenue through VAT, corporate tax, excise duty, and municipal levies. However, heavy taxation paradoxically reduces the tax base by pushing businesses into informality.
1.3 Overview of Tanzania's Tax System
Tanzania's tax system is governed by various laws and regulations under the administration of the Tanzania Revenue Authority (TRA). The key taxes affecting SMEs are summarized below:
| Tax Type | Rate | Threshold / Trigger | Impact Level | Notes |
|---|---|---|---|---|
| Corporate Income Tax | 30% | All registered companies | Very High | Highest in the sub-region; presumptive system below TZS 100M |
| Value Added Tax (VAT) | 18% | Turnover > TZS 100 million/yr | Very High | ≈ USD 40,000; triggers VAT registration obligation |
| Skills & Development Levy (SDL) | 4% | Companies with ≥ 10 employees | Moderate | Charged on gross salary; discourages formal employment |
| Withholding Tax | 2%–15% | Depends on transaction type | Moderate | Covers rent, professional fees, consultancy, dividends |
| Local Government Levies | Variable | All registered businesses | High | Business licenses, signage fees, service levies — vary by district |
| Excise Duty | Variable | Specific goods/sectors | Moderate | Affects manufacturing and importers disproportionately |
| Capital Gains Tax | Variable | On disposal of assets | Lower | Less frequently encountered by micro/small enterprises |
1.4 Problem Statement: How Tax Laws Affect SMEs
The tax laws in Tanzania create several compounding challenges for SMEs, limiting their ability to grow and contribute to the economy. Five interconnected problems emerge from the data:
- 1
High Tax Burden
SMEs face multiple taxes simultaneously — corporate tax (30%), VAT (18%), SDL (4%), and local levies — which collectively erode profitability to the point where growth becomes unsustainable for businesses operating on thin margins.
- 2
Complex Compliance Procedures
Many SMEs lack the tax knowledge and financial resources to navigate Tanzania's bureaucratic tax system. Over 60% of SMEs have inadequate understanding of tax laws, leading to costly unintentional non-compliance.
- 3
Informality and Tax Avoidance
Due to high tax rates and complex procedures, many SMEs deliberately remain informal, resulting in a narrow tax base. This paradox — high rates, low collection — weakens government revenue and perpetuates inequality between registered and unregistered businesses.
- 4
Harsh Penalties and Unfair Tax Assessments
The TRA sometimes imposes heavy backdated fines and tax assessments that are disproportionate to the size and revenue of the business. These can force SMEs into insolvency, even when the original non-compliance was unintentional.
- 5
Limited Incentives for SME Growth
Unlike large corporations which can leverage tax planning expertise and access special investment incentives, SMEs have access to very few tailored tax incentives, making it structurally harder for them to reinvest, hire, or expand.
Literature Review: Taxation & SME Growth
The existing body of research — from classical economic theory to recent World Bank enterprise surveys — consistently points to the same conclusion: Tanzania's tax system creates disproportionate barriers for SMEs. Simplified taxation, incentives, and progressive models demonstrate measurable improvements in compliance and formalization globally.
2.1 Key Features of Tanzania's Tax System
Tanzania's tax system is administered by the Tanzania Revenue Authority (TRA), established in 1995. It encompasses both direct taxes (income tax, corporate tax, capital gains tax) and indirect taxes (VAT, excise duty, import duties). A World Bank (2021) report found that over 40% of Tanzania's SMEs struggle with tax compliance, most commonly due to high costs and bureaucratic processes.
2.2 Theoretical Perspectives on Taxation and SME Growth
Classical Economic Theory (Adam Smith)
A good tax system should be fair, simple, and efficient. Excessive taxes discourage business expansion and economic activity — the "certainty" and "convenience" principles are widely violated in Tanzania's SME tax regime.
The Laffer Curve Theory
Excessive taxation reduces government revenue because businesses avoid or evade taxes. In Tanzania, high tax burdens push SMEs to the informal sector, ultimately reducing the overall efficiency of tax collection.
Cost of Compliance Theory (Allingham & Sandmo, 1972)
High compliance costs lead to lower tax compliance rates. Many Tanzanian SMEs lack in-house accountants, forcing reliance on costly external consultants — a burden that further erodes already-thin margins.
Growth-Oriented Taxation Theory
Lower tax rates and simplified procedures encourage SME formalization and expansion. An OECD (2022) study found that reducing SME tax rates by 10% increased formalization by 15% in developing countries.
2.3 Global Best Practices in SME Taxation
The following international comparisons illustrate what is achievable when tax policy actively supports SME development:
| Country | SME Tax Model | Corporate Tax Rate | Key Incentives | Outcome |
|---|---|---|---|---|
| 🇹🇿 Tanzania | Complex multi-tax system | 30% | Very limited; no SME-specific holidays | 72% informality; 78% report excessive burden |
| 🇷🇼 Rwanda | Flat turnover-based tax | 3% flat | Tiered: 0% below RWF 2M; 1–3% above | 60%+ reduction in tax evasion; high formalization |
| 🇲🇺 Mauritius | Progressive with SME holidays | 0% (5 yrs) | Tax-free first 5 years; reinvestment credits | SMEs contribute 50%+ of GDP |
| 🇬🇭 Ghana | Presumptive tax system | Fixed % | Fixed % of turnover instead of complex CIT | Higher formalization rates; broader tax base |
| 🇰🇪 Kenya | Simplified regime for small biz | 1–3% | 1–3% for revenue < KES 5M (USD 45,000) | 30%+ of SMEs formally registered vs <20% in Tanzania |
| 🇿🇦 South Africa | Progressive SBC rates | 28% | Tax rebates; tax-free threshold < ZAR 1M | Effective incentives; lower informality |
2.4 Previous Studies on SME Tax Challenges in Tanzania
International Growth Centre: Compliance as the Biggest Barrier
The IGC found that more than 70% of SMEs consider tax compliance to be their single biggest business challenge — higher than access to finance or infrastructure gaps.
| Informal operation rate | 40% operate informally due to high tax burden |
| Annual admin cost | TZS 2 million average per SME in tax-related admin |
| Primary reason for evasion | Rate complexity and high penalties |
Taxes Identified as a Major Growth Constraint
The World Bank's enterprise survey of Tanzanian businesses revealed that 50% of SMEs identify taxes as a major constraint to growth, with formalized SMEs actually suffering lower profit margins than those still operating informally.
| SMEs citing tax as constraint | 50% — highest-ranked business barrier |
| Profit margin differential | Formal SMEs earn less than informal equivalents |
| Primary reason for informality | Multiple taxation + complex filing procedures |
Progressive Tax Model Could Unlock Formalization
TICGL's own research highlighted that high compliance costs — averaging TZS 1.5 million per year — reduce SME profitability while 80% of small businesses lack proper tax knowledge, leading to accidental non-compliance rather than deliberate evasion.
| Avg. annual compliance cost | TZS 1.5 million per SME |
| Lacking tax knowledge | 80% of small businesses |
| Proposed solution | Progressive tax model tied to revenue bands |
Research Methodology
This study employed a robust mixed-method approach — combining quantitative survey data with qualitative interviews and focus group discussions — to ensure comprehensive, evidence-based findings on how tax laws impact Tanzania's SMEs.

Key Tax Law Issues Affecting SMEs in Tanzania
Six critical tax-related barriers systematically constrain SME growth in Tanzania. Each issue is backed by quantitative data from the TICGL survey and cross-referenced with secondary sources including the World Bank, TRA, and academic research.
SMEs in Tanzania face a gauntlet of overlapping tax filing requirements. The Tanzania Revenue Authority (TRA) requires separate returns for VAT, corporate income tax, and payroll taxes — each with different deadlines, formats, and penalties for late filing. The TRA's Online Tax System (OTS), while a step forward, remains inaccessible to many businesses in rural and peri-urban areas that lack reliable internet connectivity or digital literacy.

- SMEs with inadequate tax knowledge60%+Leading to unintentional non-compliance
Tanzania's corporate income tax rate of 30% is among the highest in the East African region. When combined with an 18% VAT obligation triggered at a relatively low annual revenue threshold of TZS 100 million (≈ USD 40,000), the combined tax burden quickly exceeds the financial capacity of most SMEs. Many businesses face severe cash flow problems that lead to delayed tax payments, triggering further penalties that compound the original problem.

Perhaps the most damaging structural flaw in Tanzania's SME tax environment is the multiple layers of simultaneous taxation. An SME operating in Dar es Salaam may face corporate tax, VAT, Skills & Development Levy, municipal business licenses, signage fees, district levies, and withholding taxes — all administered by different authorities, with inconsistent tax classifications leading to over-taxation.
| Tax / Levy Type | Estimated Annual Amount (TZS) | USD Equivalent | % of Revenue |
|---|---|---|---|
| Corporate Income Tax (30%) | 20,000,000 | ~8,000 | 13.3% |
| VAT Obligations (net) | 5,000,000 | ~2,000 | 3.3% |
| Business Permits & Levies | 3,000,000 | ~1,200 | 2.0% |
| SDL (4% of payroll — est.) | 2,400,000 | ~960 | 1.6% |
| Tax Consultant Fees | 1,500,000 | ~600 | 1.0% |
| TOTAL TAX BURDEN | 31,900,000 | ~12,760 | 21.3% |
- SMEs facing multiple overlapping tax layers63%
The VAT threshold of TZS 100 million creates a particularly problematic "threshold effect." Micro-businesses below the threshold avoid VAT entirely, while growing SMEs that cross it face a sudden and significant cost increase. Many businesses deliberately cap growth at TZS 99 million to avoid triggering the VAT registration requirement. Those that do register frequently lack proper accounting systems to manage VAT input/output claims, face delays in VAT refunds, and are subject to frequent TRA audits that disrupt operations.

Tanzania has one of Sub-Saharan Africa's largest informal sectors, with over 72% of businesses operating outside the formal tax system. Informality is not simply a symptom of poor business culture — it is a rational economic response to a tax system that imposes costs businesses cannot absorb. However, informality creates a damaging cycle: untaxed businesses compete unfairly with compliant SMEs, while the government loses revenue, reducing its ability to invest in the infrastructure that would help businesses grow.

The Tanzania Revenue Authority plays a critical role in tax administration, enforcement, and compliance monitoring. While TRA has made important strides in digitalizing its systems, SMEs report a predominantly adversarial relationship with the authority. Surprise audits, heavy penalties, poor communication of policy changes, and minimal taxpayer education contribute to an environment of fear rather than cooperation.

| TRA Challenge Area | Description | Impact on SMEs |
|---|---|---|
| Aggressive Tax Collection | Surprise audits; heavy penalties for minor non-compliance | Severe |
| Inconsistent Tax Policies | Frequent amendments without adequate advance communication | High |
| Limited SME Support | Minimal tax education; inaccessible taxpayer assistance services | Moderate |
| Digital Gap | Online system exists but many SMEs lack digital access | Moderate |
