What Baker Tilly Nigeria does

Baker Tilly Nigeria is a Lagos-headquartered professional services firm offering audit and assurance, tax advisory and compliance, management consulting, and company secretarial services to corporate enterprises, financial institutions, NGOs and development agencies, and public-interest bodies operating in Nigeria. The firm traces its lineage to predecessor practices Z. O. Ososanya & Co., Oyelami Soetan Adeleke & Co., and Aneni Dairo & Co., and was formed in its current form in 2008 through a merger that simultaneously brought it into the Baker Tilly International network. It operates four offices across Nigeria (Lagos, Ibadan, Abuja, and Port Harcourt) with a staff of more than 160, led by Senior Partner Oluwole Olatunde Ogundeji following the September 2023 succession from Mark Edesiri Ariemuduigho.

The firm's service portfolio is delivered through four operational arms: Audit and Assurance, BTN Tax Consultants, BTN Consulting, and the wholly-owned company secretarial subsidiary Alpha-Genasec Limited. Service delivery is partner-led across all mandates, with senior partners (most of whom are fellows of the Institute of Chartered Accountants of Nigeria and the Chartered Institute of Taxation of Nigeria) personally engaging on client matters. Notable engagements span statutory audits for Dangote Nigeria, Honeywell Flour Mills, International Breweries, Intercontinental Distillers, and donor-funded project audits for the African Development Bank, DFID, UNICEF, UNDP, UNFPA, and UNHCR. The firm uses a bespoke audit software for quality and ethics processes, and maintains an active thought leadership cadence on Nigerian tax reform, CAMA 2020, and transfer pricing regulation.

Baker Tilly Nigeria generates revenue entirely through professional services fees, which are engagement-scoped and not publicly disclosed. The firm has no external institutional investors or private equity backing; ownership rests with the partnership. Its go-to-market is sales-led and partner-led, drawing on direct enterprise relationships, referrals within the Baker Tilly International network, and sector reputation. The firm was recognized with the 2022 ICAN Merit Award in the Corporate Body category for contributions to the Nigerian accountancy profession.
