The new Nigerian tax regime, primarily driven by the
Nigeria Tax Act 2025 and the Nigeria Tax Administration Act 2025, officially took effect on January 1, 2026. For small businesses, the law introduces significant tax exemptions and simplified compliance, while strictly excluding professional service providers from these benefits.
Key Tax Reliefs for Small Businesses
A business qualifies for the most significant reliefs if it has an annual turnover of ₦100 million or less and fixed assets not exceeding ₦250 million.
- 0% Company Income Tax (CIT): Qualifying small companies are completely exempt from corporate income tax (previously 20% for turnover between ₦25m–₦100m).
- 0% Capital Gains Tax (CGT): Small companies pay no tax on the disposal of business assets or investments.
- Exemption from Development Levy: Small businesses are exempt from the new 4% Development Levy, which replaces several old charges like the Tertiary Education Tax.
- VAT Exemption: Businesses with an annual turnover of ₦50 million or less are not required to register for, charge, or remit Value Added Tax (VAT), though they may choose to do so voluntarily to claim input credits.

Exclusions & Strategic Differences
The benefits depend heavily on how your business is registered and its specific sector:
- Professional Services Exclusion: Entities providing professional services (e.g., legal, accounting, consulting, medical) are explicitly excluded from “small company” exemptions regardless of their turnover or asset size.
- LLC vs. Business Name: The 0% CIT rate typically applies to Limited Liability Companies (LLCs). Businesses registered as “Business Names” (sole proprietorships) are taxed under the Personal Income Tax (PIT) regime, which uses progressive rates from 0% to 25%.
- Personal Income Tax (PIT) Threshold: For unincorporated business owners, the first ₦800,000 of annual income is now tax-free.
New Compliance Requirements
While many small businesses may have zero tax liability, the new law introduces mandatory administrative steps:
- Mandatory Filing: Qualifying as a “small company” does not exempt you from filing. You must still file annual tax returns within 6 months of your accounting year-end.
- Tax Identification Number (TIN): A valid TIN is now mandatory for all financial transactions, including maintaining a business bank account and applying for loans.
- Digital Records: The new law emphasizes digital record-keeping. Maintaining accurate, verifiable digital sales records is a requirement for qualifying for exemptions and avoiding penalties.
- Unified Revenue Service: The Federal Inland Revenue Service (FIRS) has transitioned into the Nigeria Revenue Service (NRS), which will use digital tools and AI to detect underreporting.
