Overview of Nigeria’s 2026 Tax Reform
The Nigeria Tax Act 2025, which took effect on January 1, 2026, represents the most significant overhaul of Nigeria’s tax system in decades. The Federal Government has decided to retain the corporate income tax (CIT) rate at 30 percent for all companies, except small businesses, consolidating multiple previous tax laws into a unified framework.
This reform aims to:
– Simplify tax compliance procedures
– Provide significant relief to small businesses
– Strengthen enforcement mechanisms
– Align Nigeria with global tax standards
– Boost economic growth while ensuring fair taxation
Corporate Income Tax Rates 2026
Standard Corporate Tax Rate
The Act maintains a 0 percent CIT rate for small companies—defined as those with annual turnover below ₦25 million—while affirming a flat 30 percent rate for all other firms.
The current structure is:
| Company Size | Annual Turnover | CIT Rate |
|---|---|---|
| Small Companies | ≤ ₦100 million* | 0% |
| Large Companies | > ₦100 million | 30% |
*Note: Small company definition updated under new reforms – see section below.
Minimum Effective Tax Rate
A key innovation in the new law is the introduction of a minimum effective tax rule: large companies—especially members of multinational enterprise (MNE) groups—with annual revenue of ₦20 billion or more and an effective tax rate below 15 percent in any given year will be required to pay an additional levy to meet that threshold.
Development Levy
Development levy introduced at 4% of assessable profits. This consolidates several previous levies including:
– Tertiary Education Tax
– IT Development Levy
– NASENI Levy
– Police Trust Fund Levy
Small Business Exemptions
New Definition of Small Companies
The Nigeria Tax Act (NTA), 2025 defines a small company as: “A company that earns gross turnover of ₦50,000,000 or less per annum with total fixed assets not exceeding ₦250,000,000, provided that any business providing professional services shall not be classified as a small company.”
However, several sources indicate an even more generous threshold: Small businesses, defined as companies with an annual turnover of ₦100 million or less and fixed assets not exceeding ₦250 million, now enjoy a 0% Corporate Income Tax rate under the new law.
Benefits for Small Companies
Small companies qualifying under the new definition enjoy:
- 0% Corporate Income Tax – Complete exemption from CIT
- 0% Capital Gains Tax – You qualify for 0% Companies Income Tax, 0% Capital Gains Tax, exemption from the 4% Development Levy, and exemption from withholding tax (if monthly transactions are below ₦2 million and you hold a valid TIN)
- Development Levy Exemption – No 4% levy on assessable profits
- VAT Relief – Reduced VAT obligations
- Withholding Tax Exemption – For qualifying transactions
Exclusions from Small Company Benefits
Professional services such as legal, accounting, or medical practices, which are generally presumed to generate higher income relative to their scale are excluded from small company classification regardless of turnover.
Tax Exemptions and Reliefs
Agricultural Businesses
Companies engaged in agriculture-related activities, including crop farming, livestock, aquaculture, forestry, and dairy, receive a five-year corporate tax holiday from the start of operations.
Real Estate Investment Companies
Real Estate Investment Companies approved by the Securities Exchange Commission to operate as a real estate investment scheme in Nigeria will be exempt from income tax on rental income, and dividend income earned in a financial year will be exempt from income tax provided that at least 75% of such income is distributed within 12 months.
Employment Incentives
The new law introduces several employment-related reliefs:
- Compensation Relief – 50 percent additional deduction for salary increases, wage awards, or transport subsidies for low-income workers
- Employment Relief – 50 percent deduction for salaries of new employees hired and retained for at least three years
Start-up Investments
Investors in Nigerian labelled start-ups, such as angel investors, venture capitalists, or private equity funds, enjoy tax-exempt capital gains when they sell assets held in qualifying start-ups for at least 24 months.
Pension and Charitable Organizations
Capital gains earned by pension funds, charitable organizations, or religious trusts used for public purposes are fully exempt from tax.
Filing Requirements and Deadlines
Annual Tax Returns
Every company is under an obligation to file income tax returns with the Nigeria Revenue Service for a year of assessment, containing a duly completed self-assessment form and the other prescribed documents and information.
Key filing requirements:
– Annual filing is mandatory – Even companies with zero tax liability must file
– Self-assessment basis – Companies must calculate their own tax liability
– Digital filing mandatory – All returns must be submitted through NRS systems
VAT Returns
Every taxable person, except a small business, is required to file a Value Added Tax (“VAT”) return with the Nigeria Revenue Service not later than the 21st day of the month, in respect of all taxable supplies not exempted from VAT in the preceding month.
Registration Requirements
The Nigeria Tax Administration Act mandates that all taxable persons must register with the relevant tax authority and obtain a Tax Identification Number (TIN) by January 1, 2026.
New Compliance Requirements
Tax Identification Number (TIN)
The TIN has thus become a digital proof of compliance, directly linked to VAT filings, corporate income tax returns, development levy administration, and access to refunds or double-tax reliefs.
Without a valid TIN:
– Companies face default withholding tax rates
– No access to input VAT claims
– Penalties and restrictions apply
– Inability to obtain tax clearance certificates
Record Keeping
Maintaining accurate turnover and fixed asset records is a critical compliance requirement, especially for companies seeking to qualify as small companies under the new tax regime.
Companies must maintain:
– Contemporaneous income records
– Asset valuation documentation
– Transaction records for VAT purposes
– Employee compensation records
E-invoicing and Fiscalization
E-invoicing and data sharing between agencies enhance tracking and enforcement. VAT-registered businesses must adopt NRS-mandated e-invoicing systems.
Penalties and Enforcement
Vendor Compliance
Companies that award contracts to unregistered vendors (those without a TIN) face a massive ₦5 million penalty.
Tax Officer Obstruction
The penalty for inducing a tax officer is ₦500,000 for individuals and a staggering ₦2,000,000 for corporate bodies.
Filing Penalties
Late filing and non-payment trigger fines, interest tied to the Central Bank’s policy rate, and potential asset seizure following due process.
Key Changes from Previous System
Consolidation of Tax Laws
The Nigeria Tax Act consolidates corporate, personal, VAT, and capital gains taxes, replacing multiple previous acts with a single comprehensive framework.
Capital Gains Tax Changes
CGT rate for companies increased from 10% to 30% and harmonised with CIT. Previously, companies paid income tax under the Companies Income Tax Act at 30 percent, while capital gains were taxed separately at 10 percent. Under the new Nigeria Tax Act, all company profits, including capital gains, are combined and taxed at a flat rate of 30 percent.
Enhanced Small Business Support
The small business exemption threshold has been significantly expanded from ₦25 million to ₦100 million in annual turnover, providing relief to many more businesses.

Success under the new regime requires proactive compliance, proper registration, accurate record-keeping, and strategic planning. Companies that embrace these changes and maintain strict compliance will benefit from simplified procedures and potential tax savings, while those who fail to adapt face significant penalties and enforcement actions.
