Nigeria’s New Tax Laws and the Debate Over Private Tax Collection

Nigeria’s tax landscape is changing. The Nigeria Tax Act 2025 and accompanying reforms set to take effect in January 2026 will overhaul nearly every major tax law. These changes are designed to simplify compliance, broaden the tax base, modernise administration and increase revenue generation while aligning Nigeria with global tax practices.

Under the new framework, corporate and personal taxes have been consolidated and updated, a minimum effective tax rate of 15 percent is introduced for large and multinational companies, and multiple legacy levies are replaced by a single 4 percent development levy on assessable profits. Small companies with turnover below defined thresholds enjoy exemptions, and new rules expand the definition of taxable income to include a wider range of profits and digital assets.

Alongside these statutory tax changes, Nigeria is investing in modernising tax administration. The reforms create the Nigeria Revenue Service (NRS) as a streamlined body responsible for tax assessment, collection and accounting. This replaces the Federal Inland Revenue Service and clarifies roles across federal and state revenue agencies.

But beyond legislation, a related debate has resurfaced: whether parts of Nigeria’s tax collection should be outsourced to private firms or consultants. Historically, “tax farming” or private collection arrangements have been used in some jurisdictions including in some local government contexts where private agents are contracted to collect fees or taxes and share proceeds with government. Research in Nigeria has shown that the Federal Inland Revenue Service’s use of tax consultants correlated with increased revenue collection in certain studies, suggesting private involvement can boost effectiveness when properly managed.

Similar experiments have occurred elsewhere. Local governments in Tanzania engaged private revenue collection for property taxes with mixed results. Analysis from cities like Mwanza showed that outsourcing could increase revenues and reduce leakages, but such outcomes depend on strong data sharing, clear oversight and alignment of incentives between public and private parties conditions not always present.

Economies that experimented with tax outsourcing, such as the United States’ use of private debt collection agencies for unpaid taxes, provide further context. There, private collectors operate under contract to recover delinquent taxes, but the model has faced criticism where profit motives conflict with taxpayer rights and fair enforcement.

The pros of leveraging private entities in tax administration are clear in theory. Private firms may bring greater efficiency, specialised expertise and incentive-based performance, which can reduce corruption and improve compliance. For the government, this can translate into broader tax coverage, reduced administrative costs and faster revenue inflows especially in segments where internal capacity is weak. These benefits are often cited in academic and policy research on revenue outsourcing models.

But the cons must also be weighed carefully. Without strong oversight, private involvement can create risks of abuse, unfair collection practices, data privacy concerns and reduced accountability. Models that link collector pay to amount raised can encourage aggressive tactics that harm taxpayers and erode trust. The balance between efficiency and fairness becomes a central policy concern. International experience shows that successful private involvement relies on clear contractual frameworks, transparency, and robust legal safeguards.

For Nigeria, the debate arrives at a critical time. The new tax regime aims to widen the base and modernise the rules. But broadening enforcement without building strong administration capacity could create friction, especially among small and informal businesses that have historically operated outside formal tax compliance. Combining statutory reform with capacity-building and clear guidelines whether through public agencies or carefully regulated private partnership models will determine how effective the new system is in practice.

If Nigeria pursues private partnerships or allows private firms into parts of tax administration, it must embed safeguards that protect taxpayer rights, maintain transparency and ensure accountability. It must also invest in digital systems that reduce the cost and friction of compliance while expanding fairness.

The new tax laws mark a major shift in Nigeria’s fiscal landscape. How the government chooses to administer and enforce these laws including whether to partner with private entities will shape business sentiment, investor confidence and economic growth long after the reforms come into force. The challenge for Nigeria now lies not just in the written law, but in the systems and institutions that bring that law to life.
