How Rwanda’s Paved Highways Are Boosting Local Revenues and Business Growth

A World Bank-backed study on Rwanda finds that paving highways more than doubled local government tax revenues within five years, driven by a 269% rise in rental tax collections and a 55% increase in business license revenues. The findings suggest that quality infrastructure can strengthen local finances, stimulate small-business growth, and partially offset investment costs, offering valuable lessons for governments and development partners seeking sustainable economic development.

A new study by researchers from the University of Rwanda, the International Finance Corporation (IFC), and the National University of Singapore has found that road investments in Rwanda are generating significant fiscal and economic returns. The research challenges the traditional view that infrastructure is only a public expense, showing instead that better roads can help governments collect more revenue by stimulating business activity and raising property values.

Using data on all highway upgrades in Rwanda between 2011 and 2024, combined with 12 years of tax records and business census information, the study provides some of the strongest evidence yet that infrastructure investments can create a measurable "fiscal dividend" in a low-income country.

Local Governments See Revenues More Than Double

The most striking finding is the impact on local government finances. Municipalities located within two kilometres of newly paved highways saw their local tax revenues rise by 136 percent within five years of road upgrades. In practical terms, local revenues more than doubled after roads were paved.

The gains came mainly from two sources. Rental tax revenues increased by 269 percent as improved roads boosted land and property values. Trade licence revenues, paid by businesses operating within municipalities, rose by 55 percent over the same period.

The study estimates that road upgrades generated an additional RWF 22.2 billion in local tax revenues within six years. For local authorities struggling to finance public services, this demonstrates how infrastructure can strengthen fiscal capacity while supporting economic development.

Business Growth Drives the Fiscal Dividend

Improved roads did more than increase tax collections. They also encouraged new businesses to enter local markets.

The research found a significant rise in the number of small and medium-sized enterprises established near upgraded highways. The strongest growth occurred among firms employing between one and nine workers. Most of these businesses were informal enterprises, helping explain why local governments benefited more than the national government.

Better transport connections reduced travel times, improved access to suppliers and customers, and made previously remote areas more attractive for commercial activity. Rising business activity also contributed to higher demand for shops, offices, and commercial space, pushing up rental values and expanding the local tax base.

For private investors, the findings highlight growing opportunities in logistics, retail, warehousing, transport services, agribusiness, and real estate development along transport corridors.

Why Central Government Revenues Did Not Rise

While local governments enjoyed substantial gains, the study found almost no impact on central government tax revenues. Collections from corporate income tax, personal income tax, and value-added tax remained largely unchanged even six years after roads were upgraded.

The reason lies in Rwanda's economic structure. Most new businesses created after road improvements were small and informal, meaning they paid local trade licences but did not contribute significantly to national taxes.

This finding has important policy implications. Governments may need complementary reforms that encourage business formalization, simplify tax registration, and improve compliance if they want infrastructure investments to generate stronger national fiscal returns.

Key Lessons for Policymakers and Development Partners

The findings offer several lessons for governments and development agencies. First, infrastructure projects should be evaluated not only for their economic benefits but also for their ability to expand local tax bases and strengthen municipal finances.

Second, there is a mismatch between who pays and who benefits. In Rwanda, the central government financed the highways, but most fiscal gains accrued to local governments. Policymakers may therefore need revenue-sharing mechanisms or fiscal transfer systems that better align infrastructure costs with benefits.

For international development partners, the research suggests that transport projects can support domestic resource mobilization strategies. Combining road investments with reforms in property taxation, business registration, and local revenue administration could significantly increase long-term development returns.

The Road Ahead: Turning Infrastructure into Sustainable Growth

The study estimates that additional local tax revenues recovered about 3.1 percent of total road investment costs within six years. While modest, the researchers emphasize that this is likely a conservative estimate because it excludes property tax gains, long-term effects, and wider economic spillovers.

Another important finding is that quality matters. Road improvements that did not involve full paving produced little economic or fiscal impact. This suggests that governments should prioritize high-quality infrastructure capable of substantially reducing transport costs and improving connectivity.

As developing countries search for ways to finance growth while strengthening public finances, Rwanda's experience offers a valuable lesson. Well-designed road investments can do far more than improve transportation. They can attract businesses, raise land values, expand local tax revenues, and create a foundation for long-term economic transformation. For policymakers, development partners, and investors alike, the evidence shows that infrastructure is not simply a cost—it can be an investment that generates lasting fiscal and economic returns.
