The Nigeria Tax Act 2025, effective January 2026, has fundamentally altered the investment landscape, necessitating a shift toward after-tax return analysis. Key exemptions include interest from federal and state government bonds and dividends from authorized collective investment schemes. Additionally, foreign-sourced income may qualify for exemptions if repatriated through approved channels. Notably, capital gains for individuals are now subject to progressive personal income tax rates rather than a flat 10 percent, with specific relief available for share disposals under defined thresholds. Investors are advised to integrate tax planning into their initial asset allocation strategy to optimize returns and ensure full compliance.
