Tax policies significantly influence Tanzania’s investment climate, affecting both local and foreign investors. While taxation is crucial for government revenue, an overly complex and high tax regime can discourage investments, limit capital inflows, and slow economic growth. This article explores how tax laws shape investment trends in Tanzania, presenting key figures, challenges, and potential solutions.

Tanzania’s Tax System and Investment Trends

1. Corporate Tax Rates and Regional Comparison

Tanzania imposes a 30% corporate tax rate on resident companies, one of the highest in East Africa. In contrast:

• Kenya: 25%
• Rwanda: 28%
• Ethiopia: 25%

The high tax rate discourages investments, as seen in 2022 when Tanzania attracted only $922 million in Foreign Direct Investment (FDI), compared to Kenya’s $2 billion and Ethiopia’s $3.1 billion.

2. Tax Compliance and Bureaucracy

Tanzania ranks 163rd out of 190 countries in the World Bank’s Ease of Doing Business Index (2020), reflecting long tax compliance procedures. Businesses spend an average of 240 hours per year filing tax documents, compared to 150 hours in Rwanda.

A survey conducted by TICGL in 2025 revealed:

• 72% of investors found Tanzania’s tax system too complex.
• 63% reported high corporate taxes as a barrier to business expansion.
• 55% believed frequent tax policy changes discouraged long-term investments.

3. Multiple Taxation and VAT Burden

Investors in Tanzania face multiple layers of taxation, including:

• Corporate tax (30%)
• Withholding tax (10-15%)
• Skills and Development Levy (4%)
• Value-Added Tax (VAT) (18%)

Tanzania’s VAT refund delays are a significant issue, with pending refunds amounting to TSh 1.4–1.5 trillion ($650 million) in 2025. Some businesses wait over 12 months for VAT refunds, severely affecting cash flow and expansion plans.

4. Case Studies: How Taxes Affect Investors

Mining Industry: Acacia Mining’s $190 Billion Tax Dispute

• In 2017, Tanzania’s Revenue Authority (TRA) imposed a $190 billion tax bill on Acacia Mining.
• The dispute lasted two years, causing a 70% stock price drop and a 30% decline in FDI in the mining sector.

Telecommunications: Vodacom Tanzania’s $2.5 Million Tax Case

• Vodacom was issued a TSh 5.8 billion ($2.5 million) tax bill in 2021, disrupting its planned 5G expansion.

Tourism Sector: Serena Hotels’ VAT Refund Issues

• Serena Hotels in Tanzania faced a two-year delay on VAT refunds worth TSh 2.1 billion ($900,000), leading to cash flow problems.

Recommendations for a Better Investment Climate

1. Lower Corporate Tax to 25%
   • Aligning with Kenya and Ethiopia could increase Tanzania’s FDI inflows.
2. Simplify Tax Compliance
   • Introduce a one-stop tax portal to reduce paperwork and compliance time.
3. Reduce VAT to 16%
   • This would enhance competitiveness and reduce operational costs for businesses.
4. Automate VAT Refund Processing
   • Ensuring refunds are processed within 30 days would improve business cash flow.
5. Introduce a 5-Year Tax Stability Framework
   • This would provide predictability and confidence for long-term investors.

Conclusion

Tanzania's current tax policies present significant barriers to investment. High corporate taxes, multiple taxation, VAT refund delays, and unpredictable policy changes discourage both local and foreign investors. If key reforms are implemented—such as lowering tax rates, simplifying compliance, and improving tax administration—Tanzania could increase FDI by 10-15% over the next five years, boosting economic growth and job creation.
