For much of Africa, di informal economy no be small side story for di formal economy—na di economy itself. Nearly 90% of jobs for sub-Saharan Africa dey informal, from market traders to small manufacturers. But dis reality dey cause big contradiction. African countries get some of di lowest tax-to-GDP ratios for di world, about half of di OECD average of 30%, wey limit government ability to fund infrastructure, healthcare, and public services.
Under pressure from rising debt and tighter global financing, governments from Nigeria to Kenya and Senegal dey try to expand domestic tax collection, often focusing on di informal sector. But Brookings Institution new paper argue say many policymakers still misunderstand informality. Dem often frame informal economies as compliance failures, but informality na rational adaptation to weak public services, scarce formal jobs, limited finance, and low state capacity.
Dis tension dey sharpen as governments digitize tax collection and financial infrastructure. Kenya proposals go increase taxes on digital payments and mobile money like M-Pesa. Critics warn di measures fit slow digital adoption and push activity back to cash. Mobile money, digital IDs, and electronic payment systems give states new visibility into transactions wey before dey out of reach. But greater visibility raise fears of heavier taxation without better services, especially for rural areas where government still dey struggle.
“Di demands for compliance dey made long before any value dey delivered,” Brookings’ Pierre Nguimkeu note. Di bigger challenge be say African governments dey try to tax their way to stronger states, while many people remain informal because di state historically weak.
Moody’s ratings agency find say informal workers for Nigeria earn nine times less than formal sector workers, one of di widest income gaps for Sub-Saharan Africa. Nigeria labour market dey dominated by informal work. Millions dey counted as employed, but many dey do small-scale trading, transport, agriculture, construction, domestic services—activities wey often get unstable income, limited finance, and limited protection.
“Di disparity with di formal sector dey greatest for Sub-Saharan Africa. For example, informal workers earn nine times less than formal ones for Nigeria,” Moody’s tok. Di report come as Nigerian households still dey under pressure from high living costs after major economic reforms, including removal of petrol subsidy and naira depreciation. Although inflation don ease from earlier peaks, food, transport, and energy costs remain heavy burden.
Nigeria poverty challenge still severe. National Bureau of Statistics estimate say 133 million Nigerians, or 63% of population, dey multidimensionally poor. For many workers, di problem no be absence of work but quality of work. Informal jobs often provide daily income, but rarely offer pension, health insurance, paid leave, stable contract, or career growth. Dis leave households vulnerable to price shocks, illness, business disruption, and sudden income drop.
Moody’s say informal businesses typically small, less productive, and get limited access to capital, technology, and skills. Dis make am difficult to expand, invest, improve efficiency, or create higher-paying jobs. Informality fit help households absorb shocks because people fit quickly move into informal work during hard times, but di wider cost significant. “Although e fit help cushion shocks by allowing rapid labour and income adjustment, dis come at cost of lower productivity, limited capital accumulation and weaker income growth,” Moody’s note.
Di income gap matter for di whole economy. When most workers dey for low-productivity activities, di economy struggle to generate stronger household purchasing power, deeper savings, and broader consumer demand. Informal firms also struggle to access formal credit because many lack registration, audited accounts, collateral, or traceable financial history. Dis limit their ability to scale from subsistence-level operations to bigger businesses wey fit hire more workers and pay higher wages.
Moody’s say large informal economies weaken long-term growth by constraining investment, productivity gains, and competitiveness. “Large informal economies constrain fiscal capacity, productivity growth and policy effectiveness,” di report tok. Nigeria don introduce reforms to expand financial inclusion, digitize payments, and improve tax administration, but di size of informal labour market show how hard e be to integrate millions into formal economy.
For many informal operators, registration fit appear costly or complicated, while perceived benefits of formalization weak. Where public services poor and trust for government low, businesses and workers see little reason to enter official systems. Moody’s say reducing informality require more than enforcement—e need stronger institutions, simpler regulations, better public services, and economic growth wey create formal jobs. “Reducing informality take time, resources and political will,” di agency tok.
For Nigeria, di report suggest say narrowing di wage gap between formal and informal workers go require policies wey make am easier for small businesses to grow, access finance, improve productivity, and hire workers under stable employment arrangements. Until den, millions of Nigerians fit continue to work every day without earning enough to escape economic vulnerability.
Moody’s senior vice president Lucy Villa for CNBC Africa tok say informality factor into sovereign credit assessments indirectly by examining how much economic activity government fit effectively tax and influence through policy. Di informal sector for Africa continue to be one of contention, with estimates placing informal economy for Sub-Saharan Africa at around 36% of GDP, versus roughly 25% globally. Dis gap na structural constraint on public finances and creditworthiness.
“What matters for credit is how much economic activity can be taxed by the government and the influence the government can have over it,” Villa tok. “Formality improves that; informality reduces both.” Dis dynamic get important implications for sovereign credit quality. Broad informal sector tend to reduce government revenue, increase revenue volatility, and weaken ability to absorb shocks.
Villa push back on suggestion say African risk premiums dey artificially distorted by informality alone. Instead, she frame di issue as direct reflection of underlying credit fundamentals. Lower and less predictable revenue mean less fiscal flexibility, wey fit justify higher borrowing costs. “I don’t think it’s necessarily a question of distortion, but it’s more about the fundamentals,” she add, saying informality “naturally feeds into higher risk premium because it affects creditworthiness.”
Villa argue say widespread informality fit weaken di state at its core, creating self-reinforcing cycle where weak revenue constrain administrative capacity, and weak administrative capacity make am harder to broaden tax base or deliver effective economic policy. Still, Moody’s no advocate simplistic crackdown on informal activity. Villa acknowledge say informal sector fit serve as shock absorber, especially for economies where formal employment limited.
“I guess it’s both, and the understanding comes first,” Villa tok, referring to debate over whether government should work with informal sector rather than try to eliminate am. Better diagnostics dey prerequisite for designing tailored reforms wey fit gradually encourage formalization without undermining livelihoods. Di responsibility for building diagnostic framework dey primarily with national authorities, not ratings agencies.
For policy front, Villa point to Côte d’Ivoire and Tanzania as examples of reforms wey help bring more economic activity into formal system. Dem efforts often center on creating framework wey give households, small businesses, and corporates tangible reasons to enter formal economy. Dis fit include simplifying tax systems, improving business conditions, increasing transparency, and making rules more predictable. E also require investment in administrative systems and political backing.
“Too often we see focus on enforcement, and not the incentive,” Villa tok. She cite tax simplification and investment in right administrative systems as measures wey “yielded quite a lot of results.” Many informal enterprises operate outside formal system less out of deliberate tax evasion than because formal compliance costly, complex, or perceived to offer little benefit. Reforms wey reduce dem frictions fit help create virtuous cycle.
Villa describe potential gains for continent as “massive.” With estimated 36% of GDP for Sub-Saharan Africa sitting in informal sector, even partial progress fit materially improve revenue performance over time. She caution say change go be gradual, but e no unreasonable to expect say countries pursuing sustained reform over decade fit capture meaningful share of dat activity. Reduction in informality fit support stronger income growth, deeper economic development, and more resilient sovereign balance sheets.
For policymakers across Africa, Moody’s message be say informality no be solely policing problem—na governance, administrative, and incentive-design challenge. Countries wey fit simplify compliance, strengthen institutions, and demonstrate say tax revenues dey used effectively fit be better placed to convert informal activity into broader formal tax base. For region where access to affordable financing critical for development, dat transition fit eventually lower sovereign risk and improve credit outcomes.
