The Nigeria Tax Act (NTA) repeals and replaces several major tax laws, including the Companies Income Tax Act (CITA), Personal Income Tax Act, Petroleum Profits Tax Act, Value Added Tax Act, Capital Gains Tax Act, and Stamp Duties Act,  marking a sweeping overhaul of Nigeria’s tax framework. The new law consolidates multiple regimes into a single, unified legislation aimed at simplifying compliance and aligning with global standards.
