Introduction
The enactment of the Nigeria Tax Act, 2025 (NTA 2025) marks a decisive turning point in Nigeria’s tax jurisprudence. Although the Act did not, in strict terms, introduce entirely new taxes unknown to the former regime, it significantly restructured existing tax thresholds and compliance mechanisms, particularly in relation to personal income tax.
One of the most critical reforms introduced by the Act is the clear definition of the minimum taxable personal income. This concept was previously obscured under the repealed tax laws. It must be emphasised from the outset that under the new regime, taxability does not attach to income in the abstract, but to chargeable income after statutory adjustments.
Accordingly, the correct legal inquiry is not how much an individual earns in gross terms, but rather: At what level of chargeable income does personal income tax liability begin under the Act? This article therefore seeks, without mincing words, to provide a brief but clear analytical clarification of this question anchored strictly on the provisions of the Act.
The Statutory Position under the Act
Under the Fourth Schedule to the Nigeria Tax Act, 2025, which prescribes the personal income tax rate structure, the first tax band is expressly stated as follows:
₦0 – ₦800,000: Tax rate – 0%
The legal implication of this provision is straightforward: chargeable income up to ₦800,000 per annum attracts no personal income tax whatsoever. Consequently, an individual becomes liable to personal income tax only when his or her chargeable income exceeds ₦800,000, and not merely because the individual earns income.l
Based on this position, income that is below or equal to ₦800,000 is non-taxable, not because it is exempted by discretion or concession, but because it falls squarely within a statutory zero-rate band. Tax liability therefore begins only from the first naira earned above ₦800,000.
2. Chargeable Income vs Gross Income
A clear distinction must be drawn between gross income and chargeable income under the new tax regime. The Nigeria Tax Act, 2025 deliberately and carefully distinguishes between the two.
Under sections 28–30 of the Act, the gross income of an individual is first reduced by allowable deductions and statutory reliefs, which include:
a. Pension contributions;
b. National Housing Fund (NHF) contributions;
c. National Health Insurance Scheme (NHIS) contributions;
d. Interest on loans obtained for the development of an owner-occupied residential house;
e. Any annuity or premium paid by the individual for insurance on his life or the life of his spouse during the year preceding the year of assessment; and
f. Rent relief amounting to 20% of annual rent paid, subject to a maximum of ₦500,000.
(see section 30 of the Act).
What remains after these deductions is the individual’s chargeable income, to which the Fourth Schedule applies. In simple terms, only an individual whose income exceeds the ₦800,000 threshold after these deductions becomes liable to tax under the Act. The implication is clear: an individual may earn more than ₦800,000 in gross income, yet still fall below the minimum taxable threshold once the statutory reliefs are applied.
3. Comparison with the Former Tax Regime (PITA)
Under the repealed Personal Income Tax Act (PITA), there was no explicit minimum taxable income embedded within the rate structure. Even the lowest band of taxable income attracted tax at the rate of 7% after reliefs.
Under PITA, the concept of tax-free income existed only indirectly through allowances, rather than through an express zero-rate band. This often created ambiguity as to when tax liability truly began.
By contrast, the Nigeria Tax Act, 2025, introduces a clear statutory tax-free threshold, thereby removing uncertainty regarding the commencement of tax liability. This reform represents a paradigm shift from relief-based protection to rate-based technical exemption, anchoring tax justice more firmly in the rate structure itself.
4. Significance of the Minimum Threshold Policy
The introduction of a minimum taxable threshold of ₦800,000 reflects deliberate and thoughtful policy choices capable of producing positive socio-economic outcomes.
First, the law recognises that income below this threshold lacks meaningful tax capacity. The State therefore shows little interest in extracting revenue from individuals who evidently have limited financial standing. This approach may also encourage small-scale and grassroots economic activities, allowing them room to grow before tax obligations arise.
Secondly, the Act avoids taxing income required for basic living needs, such as housing, rent, life insurance, and health insurance. In doing so, the law aligns personal income taxation with fundamental welfare considerations.
Lastly, the minimum threshold policy promotes voluntary tax compliance. Individuals whose income falls close to the threshold have little or no incentive to conceal income, since the first band of chargeable income is tax-free. This may enhance transparency and strengthen trust between taxpayers and tax authorities.
Conclusion
The Nigeria Tax Act, 2025 introduces much-needed clarity into the determination of the minimum taxable personal income in Nigeria. By expressly subjecting chargeable income up to ₦800,000 to a 0% tax rate, the Act establishes a clear, predictable, and equitable starting point for personal income tax liability.
This reform not only departs from the ambiguities of the former tax regime but also reflects a conscious policy choice to protect low-income earners, promote economic stability, and encourage voluntary compliance. Ultimately, the minimum taxable threshold under the Act underscores a broader shift attempt in Nigeria’s tax philosophy; from mere revenue extraction to fairness and social sensitivity.
