Introduction

Nigeria’s recent tax reforms have introduced a presumptive tax framework aimed at bringing the large informal sector into the formal tax system. The reform is part of broader fiscal modernization designed to simplify tax compliance, expand the national tax base, and improve transparency in tax administration.

Presumptive taxation targets individuals and small businesses whose income cannot easily be determined because they do not maintain formal accounting records. This includes many market traders, artisans, transport operators, and small retail businesses across the country.

The framework builds on provisions under the Personal Income Tax Act and is coordinated nationally through tax harmonization mechanisms led by the Joint Tax Board.

How Presumptive Tax Will Affect Market Traders and Artisans

Presumptive tax primarily applies to informal sector participants, including:

  • Market traders
  • Artisans (tailors, mechanics, carpenters, welders)
  • Small retail shop owners
  • Informal service providers
  • Transport operators

These groups often operate outside the formal accounting system, making it difficult for tax authorities to assess their income using conventional tax rules.

Key Implications

Simplified tax calculation

Instead of preparing financial statements, taxes may be determined using simplified indicators such as estimated turnover, type of business, and scale of operation.

Low tax rates

Under current policy discussions, presumptive tax may apply low turnover-based rates, often around 1% of turnover, to reduce compliance burdens.

Protection for very small businesses

Micro enterprises with very low turnover may be exempt from presumptive taxation to avoid overburdening subsistence businesses.

Encouragement of formalization

By simplifying compliance, the system aims to gradually integrate informal businesses into the formal economy, allowing them to benefit from government programs and financial services.

Impact on Lagos Market Associations (Iyaloja / Babaloja System)

In markets across Lagos and many other Nigerian cities, tax collection has historically been coordinated through market associations led by Iyaloja (female market leaders) and Babaloja (male market leaders).

These associations often collect levies from traders and remit them to government authorities or local administrations.

Possible Changes Under the Presumptive Tax System

Individual taxpayer registration

Traders may be required to register directly with tax authorities rather than relying solely on association-based collections.

Digital tax payment systems

Payments are expected to be made through official electronic channels to eliminate informal cash collection.

Reduced intermediary role

Market associations may shift from collecting taxes to assisting with tax education, compliance awareness, and trader registration.

Greater transparency

Formal systems can reduce the risk of multiple unofficial levies being imposed on traders.

Because the Iyaloja/Babaloja system plays an important role in market governance, successful implementation will likely require consultation with market leaders and associations.

Possible Constitutional Issues Between Federal and State Tax Powers

Nigeria operates a federal tax structure, meaning taxation powers are shared between federal and state governments.

The Personal Income Tax Act assigns responsibility for collecting personal income tax from individuals to state governments.

However, presumptive tax policy is often designed at the national level through the Federal Ministry of Finance and coordinated by national tax bodies.

Potential Legal Questions

Jurisdiction overlap

States may assert that taxation of traders and artisans falls strictly within their authority.

Uniform tax schedule vs state autonomy

Federal guidelines may introduce standardized presumptive tax structures, but states may wish to adapt them to local economic realities.

Administrative responsibility

Questions may arise regarding which institutions should enforce the system:

  • State Internal Revenue Services
  • Federal tax agencies.

These issues are typically addressed through coordination mechanisms such as the Joint Tax Board, which harmonizes tax administration across Nigeria.

Why Some Experts Predict Resistance from the Informal Sector

Although presumptive taxation is designed to simplify compliance, some experts believe the reform could face resistance from informal sector participants.

Key Concerns

Fear of new tax burdens

Many traders currently pay only local market levies or association dues. Formal taxation may be perceived as an additional financial obligation.

Trust deficit

Some business owners remain skeptical about whether tax payments will translate into improved public services such as infrastructure, sanitation, and market facilities.

Risk of multiple levies

If coordination between government agencies and market associations is weak, traders may still face:

  • association levies
  • local government charges
  • presumptive tax.

Enforcement concerns

Past experiences with aggressive tax enforcement can create apprehension among informal sector operators.

Policy Safeguards Built into the Reform

To address these concerns, the presumptive tax framework includes several safeguards:

  • Low and simplified tax rates
  • Possible exemptions for micro enterprises
  • Elimination of roadside tax collection
  • Digital payment channels to improve transparency
  • Harmonization of taxes through national coordination mechanisms.

These safeguards are intended to ensure the presumptive tax system remains fair, simple, and predictable.

Conclusion

Presumptive taxation represents a significant shift in Nigeria’s approach to taxing the informal sector. By simplifying compliance and expanding the tax base, the system aims to gradually integrate informal businesses into the formal economy while maintaining manageable tax obligations.

The long-term success of the reform will depend on:

  • effective coordination between federal and state tax authorities
  • engagement with market associations and informal sector groups
  • transparent and fair tax administration.

If implemented carefully, presumptive taxation could play a key role in strengthening Nigeria’s revenue system while supporting inclusive economic growth.
