Introduction

The Joint Revenue Board's announcement that 21 states have harmonised their tax laws marks a pivotal shift in Nigeria's fiscal landscape. The move replaces a patchwork of over 100 subnational levies with a standardised framework designed to modernise revenue collection.

What Happened

Executive Secretary Mr. Olusegun Adesokan revealed the development during a press conference attended by Nairametrics, noting the transition follows the Federal Government's implementation guidelines for the new Tax Acts 2025, effective January 1, 2026. The board emphasised that 21 states have now passed the Model Harmonised Taxes and Levies Law, standardising nine key tax heads including income tax, stamp duties, property tax, road tax, haulage levy, economic development levy, harmonised levy, user charge, and daily ticket. Several states are already leveraging JRB-supported technology to streamline revenue administration.

Why This Matters

The harmonisation effort targets the elimination of duplicate taxes, improved compliance, and a lighter administrative burden for small businesses. By consolidating more than 100 fragmented levies into a coherent system, the reform aims to create a more predictable and efficient tax environment. In a related move, the JRB affirmed zero tolerance for roadblocks erected to facilitate cash collection on highways, pledging to strengthen collaboration with the Nigeria Police Force to apprehend defaulters.
