The Act introduced significant changes to the corporate tax landscape, impacting how companies are taxed in Nigeria. Understanding these amendments is essential for businesses to navigate the revised tax provisions, optimize their tax planning, and ensure compliance with the new requirements. As an audit firm dedicated to educating and empowering our prospective customers, this article aims to provide a comprehensive understanding of the amendments made to the Companies Income Tax Act (CITA) by the Nigeria Finance Act 2020.


Reduction in Minimum Tax Rate:

The Finance Act 2020 decreased the minimum tax rate for companies from 0.5% to 0.25% of their gross turnover. This change reduces the tax burden on companies, particularly those experiencing low-profit margins, allowing them to retain more of their earnings for reinvestment and growth.


Taxation of Insurance Companies:

The Act introduced specific provisions for the taxation of insurance companies, including adjustments to the rules governing the computation of profits and deductions allowed for insurance-related expenses. Insurance companies need to familiarize themselves with these new provisions to ensure accurate tax calculations and compliance.


Amendments to Thin Capitalization Rules:

The Finance Act 2020 made amendments to the thin capitalization rules to prevent excessive interest deductions. The new rules limit the interest expense deduction to 30% of earnings before interest, tax, depreciation, and amortization (EBITDA) for companies exceeding the prescribed debt-to-equity ratio. These changes aim to curb profit shifting and ensure a fair distribution of tax liabilities.


Introduction of Group Tax Relief:

The Act introduced group tax relief provisions, allowing companies within the same group to offset losses incurred by one entity against the profits of another. This provision encourages intra-group collaboration, supports business consolidation, and provides tax benefits for companies operating as part of a group structure.


Taxation of Real Estate Investment Trusts (REITs):

The Finance Act 2020 introduced provisions for the taxation of income derived from real estate investment trusts (REITs). Previously, REITs enjoyed tax exemptions, but they are now subject to taxation on their rental income and other profits. This change affects both REITs and investors in the real estate sector and requires careful tax planning and compliance.


Tax Exemptions for Small Companies:

The Act introduced tax exemptions for small companies with an annual turnover of less than N25 million. Such companies are now exempt from income tax, relieving them of the tax burden and supporting their growth and development. Small businesses should assess their eligibility for this exemption and ensure compliance with the criteria set forth in the Finance Act.


Increased Penalties for Non-compliance:

The Finance Act 2020 significantly increased the penalties for non-compliance with tax obligations. The Act empowers tax authorities to impose penalties for late filing, incorrect filing, failure to provide accurate information, and other compliance-related offenses. It is crucial for companies to prioritize timely and accurate tax filing to avoid penalties and mitigate compliance risks.



The amendments to the Companies Income Tax Act introduced by the Nigeria Finance Act 2020 bring significant changes to the corporate tax landscape. Understanding these amendments is essential for businesses to optimize their tax planning strategies, ensure compliance with the new requirements, and mitigate potential penalties. As an audit firm, we are committed to assisting our prospective clients in comprehending and navigating these amendments, providing them with the knowledge and guidance needed to thrive in the evolving Nigerian tax environment and achieve their business objectives.
