Senate Approves Harmonized Tax Reform Bills

The Nigerian Senate passed the harmonised tax reform bills On May 28, 2025, marking a major overhaul of the country’s fiscal framework. These four landmark bills originally sent to the National Assembly in October 2024 are designed to unify and simplify Nigeria’s complex tax regime.

What Bills Were Harmonised?

1. Nigeria Revenue Service (Establishment) Bill
   
2. Nigeria Tax Administration Bill
   
3. Nigeria Tax Bill 2024
   
4. Joint Revenue Board (Establishment) Bill
   

By merging overlapping statutes into a single, coherent code, lawmakers aim to eliminate conflicting regulations and reduce compliance costs for businesses.

The Conference Committee Process

Because both the Senate and the House of Representatives had approved different versions, a Conference Committee chaired by Senator Mohammed Sani Musa met to reconcile discrepancies. After joint deliberations, the committee produced harmonized versions that reflect input from both chambers. The unified bills were then presented back to the Senate for final approval.

Key Benefits of Harmonisation

• Clearer Framework: A single tax code removes ambiguity and conflicting clauses.
  
• Enhanced Enforcement: Streamlined procedures and stricter penalties will deter evasion.
  
• Improved Ease of Doing Business: Businesses will file one return instead of multiple forms.
  
• Broader Base: Consolidation makes it easier to bring more enterprises especially SMEs into the formal tax net.
  

Next Steps Toward Presidential Assent

With the Senate’s approval secured, the harmonized bills will now go to President Bola Tinubu for assent. If signed into law, the reforms could take effect as early as Q4 2025, giving authorities time to update systems and train tax administrators on the new provisions.

What This Means for Stakeholders

• Businesses should begin reviewing the consolidated code to understand how definitions and rates have changed.
  
• Tax Practitioners must prepare to guide clients through updated filing requirements.
  
• Government Agencies will need to upgrade IT infrastructure for unified electronic returns and real-time monitoring.
