Nigeria's Companies Income Tax Act (CITA) grants full exemption from corporate income tax to eight specified categories of organisations, shielding them from the statutory 30 percent tax rate that applies to most corporate entities. The exemptions are codified under Section 23 of the Act and reflect deliberate legislative intent to advance public welfare, social cohesion and economic development.
The first category covers statutory bodies and government institutions. These include federal and state parastatals, ministries, departments and agencies that derive their existence from enabling legislation. Because their mandates are fundamentally public-service oriented and non-commercial in character, the law exempts them from corporate taxation.
Ecclesiastical, charitable, benevolent or educational institutions of a public character constitute the second exempt category. To qualify, the institution must demonstrate that its activities serve the public interest rather than private profit. Income derived from trading activities unrelated to the institution's core charitable or educational purpose, however, may still attract tax.
Trade unions registered under the Trade Unions Act fall within the third exempt group. The exemption recognises that trade unions exist primarily to advance the collective bargaining interests of their members and are not profit-seeking ventures.
Fourth are cooperative societies registered under the Cooperative Societies Act. Given their foundational principle of mutual assistance among members, the law treats their surplus distributions as rebates rather than taxable profits, provided the societies operate strictly within cooperative principles.
Friendly societies, the fifth category, operate along mutual-benefit lines similar to cooperatives. They pool member contributions to provide welfare support during illness, unemployment or bereavement and are exempt so long as they do not engage in profit-oriented trading.
The sixth exemption applies to clubs, associations or societies that exist for recreational, cultural or social purposes and do not trade for profit. Income from member subscriptions and related activities remains exempt, but profits from commercial trading arms are taxable.
