History of Accounting in Nigeria: From Colonial Roots to IFRS Adoption

Nigeria's accounting profession evolved from colonial imposition to a globally recognized, IFRS-compliant system—driven by visionary practitioners, legislative milestones, and economic necessity.

Foundational Era (1950s–1960s)

• 1952: Akintola Williams & Co. founded by Chief Akintola Williams (1919–2023), Nigeria's first indigenous chartered accountant (ICAEW, 1949). The "father of Nigerian accountancy" built the profession's institutional backbone.
• 1960: Independence — profession still UK-linked (ICAEW, ACCA dominance)
• 1961: Nigerian Institute of Accountants (NIA) formed — first local professional body

Regulatory Framework (1970s–1990s)

• 1965: Companies Act (based on UK 1948 Act) — first statutory accounting framework
• 1976: Public Accountants Decree No. 31 — mandatory NIA registration for public practitioners; created Accountants Registration Board of Nigeria (ARBN)
• 1979: Institute of Chartered Accountants of Nigeria (ICAN) established by Decree No. 15 — replaced NIA; became sole chartered body
• 1982: Association of National Accountants of Nigeria (ANAN) founded — second chartered body (Decree 76, 1993)

Standards Convergence (1990s–Present)

• 1992: Nigerian Accounting Standards Board (NASB) established — set Nigerian SAS (Statements of Accounting Standards)
• 1999: Companies and Allied Matters Act (CAMA) — replaced 1968 Act; strengthened regulation; 2020 amendment (CAMA 2020) modernized further
• 2010: Financial Reporting Council of Nigeria (FRCN) Act — replaced NASB; unified standard-setting, audit regulation, corporate governance
• 2011: IFRS adoption — Nigeria mandated IFRS for public interest entities (phased: 2012 listed, 2013 others, 2014 SMEs)
• 2020: CAMA 2020 — enhanced corporate governance, beneficial ownership, virtual meetings

Current Landscape

• Professional bodies: ICAN (~50K members), ANAN (~10K), CIPFA Nigeria, CIMA Nigeria
• Standards: IFRS (full), IFRS for SMEs, IPSAS (public sector)
• Regulator: FRCN (standard-setting, audit oversight, corporate governance)
• Challenges: Enforcement capacity, SME compliance, public sector transition, talent retention

From Akintola Williams' ledger to IFRS convergence, Nigerian accountancy has become a continental leader—now exporting expertise across Africa.
