Many Nigerian founders have treated tax as an afterthought — something to worry about only when the revenue service comes knocking. That approach is now a costly mistake. The Nigeria Tax Act 2025, signed into law in June 2025 and effective from 1 January 2026, has swept away more than twenty fragmented tax laws and replaced them with a single, unified code that touches almost every decision a startup makes, from how you register your company to how you pay your team and eventually sell your business. The message from the government is clear: the system is now designed to reward formal, compliant businesses while making non-compliance far more expensive.
For startups and small businesses, the headline is genuinely encouraging. The law expands the definition of a “small company” and hands that category a set of reliefs that could keep thousands of early-stage ventures out of the corporate tax net entirely. But the reliefs come with conditions, and the compliance obligations are real. Understanding both sides of the equation is the first step to building a business that grows without tax surprises.
Who Counts as a Small Company Under the New Law
The most important threshold for any Nigerian startup to understand is the small-company test. Under the Nigeria Tax Act 2025, a small company is one with annual gross turnover of ₦100 million or less and total fixed assets of ₦250 million or less. There is one critical exception: businesses that provide professional services cannot be classified as small companies, no matter how modest their turnover. If your startup sells consulting, legal, accounting, or similar professional services, you fall outside this protective category and should plan accordingly.
The expansion of this definition is significant because it removes the old “medium company” category that once trapped growing businesses in a maze of minimum tax obligations. A company that previously earned between ₦25 million and ₦100 million and paid tax even in loss-making years now qualifies as small, provided it meets the asset test. For founders who deliberately kept their businesses informal to avoid disproportionate tax burdens, the calculus has changed: registration now opens the door to reliefs rather than inviting a heavy bill.
Zero Company Income Tax and the End of Minimum Tax
A qualifying small company is fully exempt from Company Income Tax, Capital Gains Tax, and the newly introduced 4% Development Levy. In plain terms, if your startup stays within the turnover and asset thresholds, the government allows you to keep your profits instead of sharing them with the tax authority. The old minimum tax regime, which taxed companies even when they declared little or no profit, has been deleted for small businesses. That change alone can transform cash flow for a young company that is still finding its feet.
The relief does not apply once you cross the threshold. A business with annual turnover just above ₦100 million now faces the full corporate tax regime, with no transitional buffer. Founders planning rapid growth should model the tax impact of crossing that line before it happens, rather than discovering it at the end of the financial year.
VAT: Relief for Small Companies and a Higher Registration Bar
Value Added Tax has historically been one of the most burdensome compliance obligations for small Nigerian businesses. The new law changes that in two ways. First, small companies — those within the ₦100 million turnover and ₦250 million fixed-asset limits, excluding professional-services firms — are exempt from the obligation to register for, charge, and remit VAT. Second, for businesses outside that small-company definition, the VAT registration threshold has been raised to ₦50 million in annual turnover, meaning a business below that line is not required to register.
Small companies that want to claim input VAT on their business expenses can still choose to register voluntarily, but doing so brings them fully within the VAT compliance net. The exemption is a relief, not a permanent shelter; once turnover grows beyond the small-company ceiling, VAT obligations begin. The practical effect for most early-stage startups is that VAT does not bite until the business has grown well beyond its first few million naira in sales.
Withholding Tax Relief on Small Payments
The law also removes a cash-flow headache that has frustrated small businesses for years: withholding tax on low-value transactions. Payments below ₦2 million are now exempt from withholding tax, provided the receiving business has a valid Tax Identification Number. For a startup that regularly invoices larger clients for modest contracts, this means receiving the full payment without waiting for a portion to be remitted to the tax authority. The relief is conditional on having a TIN, which reinforces a broader theme of the new regime: formal registration is the gateway to benefits.
What Founders Pay Themselves and Their Teams
The personal tax side of the law matters just as much as the corporate side, especially for founders who draw salaries or plan to reward early employees with equity. The first ₦800,000 of annual personal income is now tax-exempt, and the rates that follow are progressive, rising through bands that cap at 25% for the highest earners. For a founder deciding between salary and dividends, the calculation has shifted: salary is taxed at progressive personal rates, while dividends and capital gains follow their own rules.
Share options, a common tool for startups that cannot yet match corporate salaries, now carry two taxable moments. When an employee exercises an option, the discount between the share’s value and the price paid is treated as part of their pay and taxed immediately, even though no cash has changed hands. When the employee later sells the shares, any further gain is a separate capital gain. Option plans written before 2026 may need to be revisited, because they can inadvertently leave employees with a tax bill on paper gains they cannot fund.

Capital Gains and the Exit Conversation
For founders thinking about an eventual sale, the capital gains landscape has changed materially. The flat 10% rate that once applied to share disposals is gone. Gains are now taxed at the ordinary rate — up to 30% for a company and up to 25% for an individual, following the same progressive structure as personal income tax. A gain that a founder once budgeted at ₦10 million in tax could now attract two or three times that amount.
There is a further complication for venture-backed startups. If the Nigerian operating business sits beneath a foreign holding company — a structure many investors prefer — the sale of shares in that offshore parent can still trigger Nigerian tax where most of the parent’s value derives from the Nigerian business. Exit planning that begins only when a buyer appears is now too late; the ownership structure chosen at incorporation has a direct bearing on how much of the sale proceeds a founder actually keeps.
Incentives for Growth and Innovation
The law does not only impose obligations; it also offers targeted incentives for businesses that invest and innovate. The Economic Development Incentive replaces the old Pioneer Status regime with a 5% annual tax credit on qualifying capital expenditure for up to five years, available to eligible companies in designated priority sectors. Research and development expenses are deductible, subject to a cap of 5% of turnover for the year. For startups that have obtained the official Startup Label under the Startup Act, additional benefits include expedited and reduced-cost intellectual property registration, access to the Startup Investment Seed Fund, and regulatory sandbox access for testing innovative products.
These incentives are not automatic. Eligibility depends on sector classification, proper registration, and compliance with filing obligations. A founder who treats the Startup Label as a badge rather than a set of substantive requirements may find that the expected reliefs do not materialise.

The Compliance Habits That Keep Reliefs Alive
The single most important message for startups under the Nigeria Tax Act 2025 is that reliefs are conditional on compliance. A small company that fails to register, file returns, or maintain proper records can lose the very exemptions that make the regime attractive. Every business needs a valid Tax Identification Number, not only to receive withholding-tax-free payments but to interact with the revenue system at all. Returns must be filed on time, and records must be kept accurately.
The transition to the new regime has been supported by formal guidelines issued by the Federal Ministry of Finance, which clarify that tax liabilities for periods before 1 January 2026 remain governed by the old laws, while returns falling due from that date onward are administered under the new framework. For a startup incorporated before 2026, that means the first set of returns under the new law is the moment to ensure the business is correctly classified and that its compliance house is in order.
The Nigeria Tax Act 2025 is not a reason for startups to fear the tax authority. It is a reason to take tax seriously from day one. The businesses that benefit most will be those that register early, keep clean records, monitor their turnover against the small-company thresholds, and seek advice before making structural decisions about ownership, hiring, and exit.
