Tanzania is entering a defining phase in its economic evolution. With a population of 65.23 million people, the country possesses a large and dynamic domestic market, a growing labor force, and increasing digital connectivity. These fundamentals position Tanzania as one of East Africa’s most promising economies. However, the real opportunity lies not just in growth, but in how effectively that growth is captured, measured, and reinvested.

In the digital age, economic expansion is closely tied to how well governments can harness technology to improve transparency, efficiency, and revenue collection. For Tanzania, digital transformation presents a clear pathway to increasing GDP — not through raising taxes, but by closing gaps, reducing inefficiencies, and formalizing economic activity.

In this post, we’ll explore three high-impact areas where digital solutions can unlock substantial economic value: excise tax collection through track and trace systems, reducing the VAT gap by implementing e-invoicing, and formalizing informal employment by introducing a self-employment tax solution.

Strengthening Excise Tax Collection: The Role of Digital Track and Trace 

Excise goods such as alcohol and tobacco are critical contributors to government revenue. However, according to the Organized Crime Index, illicit trade in these products is highly prevalent in Tanzania, with smugglers routinely evading taxes on goods such as alcohol and cigarettes, among others. 

As also reported by The Chanzo and Daily News, the scale of the issue is significant. For example, the illicit trade of alcohol alone constitutes more than half of the overall beer market in Tanzania — 55%, which is equivalent to US $8.8 billion. This highlights a systemic issue that undermines both public revenue and consumer safety. 

Digital track and trace systems offer a powerful solution. By assigning secure, unique identifiers to products and tracking them across the supply chain, governments gain real-time visibility into production, distribution, and sales. This makes it significantly more difficult for illicit goods to circulate undetected and ensures that excise taxes are properly collected. 

The financial impact is substantial. For example, if Tanzania were to implement traceCORE Digital Track and Trace for alcohol and tobacco alone, the country could collect an additional US $8.05 billion in revenue. Beyond revenue gains, such systems also improve market fairness, protect consumers, and strengthen regulatory oversight. 

Closing the VAT Gap: Digital Transformation Through E-Invoicing 

Value Added Tax (VAT) is one of the most important sources of government revenue in Tanzania, yet it is also one of the most vulnerable to inefficiencies and fraud. The VAT gap in Tanzania currently stands at a staggering 62%, according to the information provided by the IMF and UNU-WIDER, which indicates that a significant portion of potential revenue is not being collected. 

Based on available data, Tanzania’s annual VAT loss is estimated at approximately US $4.2 billion. This gap is driven by underreporting, informal transactions, weak enforcement mechanisms, and outdated manual processes. 

The introduction of B2B and B2C e-invoicing systems can dramatically improve this situation. By digitizing invoices and integrating them directly with tax authority systems, transactions are recorded in real time, reducing opportunities for manipulation and increasing transparency. 

With the implementation of advanced e-invoicing solutions, such as those provided by traceCORE, Tanzania has the potential to reduce the VAT gap from 62% down to just 5%. According to our estimates, the adoption of traceCORE B2B and B2C E-Invoicing would allow the government to recover approximately US $3.9 billion annually in lost revenue. 

For the government, e-invoicing ensures a more stable and predictable revenue stream, enabling better fiscal planning and investment. For businesses, it delivers operational benefits, including reduced administrative burdens, improved accuracy, and faster financial processes.  

Reducing Informal Employment: A Path to Inclusive Growth 

A major structural challenge for Tanzania’s economy is the scale of informal employment. Currently, 83% of the workforce — equivalent to 25.9 million people — operates in the informal sector, as reported by ILO. While this sector provides livelihoods, it limits productivity, reduces tax contributions, and restricts access to financial services. 

Formalizing this segment of the economy is essential for sustainable and inclusive growth. However, traditional tax systems are often too complex and inaccessible for self-employed individuals and small entrepreneurs. 

Digital self-employment tax solutions provide a practical and scalable approach to addressing this issue. By leveraging mobile platforms and simplified tax processes, individuals can easily register, declare income, and pay taxes without significant administrative burden. 

Through the introduction of digital solution like traceCORE Self-Employment Tax Solution, Tanzania can engage approximately 12.5 million self-employed workers in formal economic activity. This transition would not only broaden the tax base but also generate an additional US $1.5 billion in government revenue, according to our estimates. 

Beyond revenue collection, formalization empowers individuals. It enables access to credit, insurance, and social protections, fostering greater economic security and upward mobility. 

The Combined Impact: A Data-Driven Economy 

Individually, each of these solutions addresses a critical gap in Tanzania’s economic system. Together, they create a powerful, integrated digital transformation ecosystem for growth. 

• Digital track and trace strengthens excise tax compliance and reduces illicit trade. 

• E-invoicing closes the VAT gap and enhances transparency. 

• A self-employment tax solution expands the formal economy and broadens the tax base. 

The combined effect is a more transparent, efficient, and inclusive economy. Increased government revenues can be reinvested into infrastructure, education, and healthcare, while improved regulatory systems enhance investor confidence and support private sector growth. 

The Implementation Challenge: Why Expertise Matters 

While the benefits of digital transformation are clear, successful implementation is far from guaranteed. Technology alone does not deliver results. Without the right regulatory frameworks, institutional readiness, and strategic execution, digital initiatives can fail to achieve their intended outcomes. 

Challenges such as low adoption rates, resistance from stakeholders, poor system integration, and lack of technical expertise can significantly undermine progress. In some cases, poorly implemented systems can even create new inefficiencies rather than solving existing ones. 

This is why it is not effective to introduce digital transformation solutions without the necessary knowledge and experience. Governments must adopt a strategic, well-informed approach that aligns technology with policy, infrastructure, and user needs. 

Choosing the right advisory partner is therefore critical. traceCORE brings specialized expertise in designing and implementing digital tax transformation systems, with a focus on practical, results-driven outcomes. Our approach combines deep technical knowledge with an understanding of regulatory environments and on-the-ground realities, ensuring that solutions are not only technically sound but also widely adopted and sustainable.

By supporting governments through every stage — from strategy and system design to rollout and optimization — traceCORE helps minimize risks, accelerate implementation, and maximize revenue impact. 

Conclusion: Turning Potential into Measurable Growth 

Tanzania has a unique opportunity to accelerate its economic growth by embracing targeted digital transformation initiatives. The country is well-positioned to benefit from improved revenue collection, increased transparency, and broader economic participation. 

However, realizing this potential requires more than ambition — it requires expertise. Implementing digital transformation solutions demands careful planning, technical know-how, and proven experience. 

Partnering with advisory experts such as traceCORE can help ensure that these initiatives are designed and executed effectively, delivering measurable and sustainable results. In the digital age, successful growth is more than just adopting new technologies, it is about using them strategically to unlock real economic value.
