Trusted Nigerian expertise.
International standards.
For decades, Tamuno George & Co. has been a trusted partner to businesses, investors and individuals navigating Nigeria's financial, regulatory and tax environment. As a full-service, independent firm of Chartered Accountants, we combine deep local knowledge with the technical rigour international clients expect — making us a natural partner for foreign companies and investors entering or operating in the Nigerian market.
An integrated suite of services
Whether you are establishing a new venture in Lagos, managing cross-border tax obligations, or seeking dependable audit and assurance services, our multi-disciplinary team — spanning accounting, tax, legal and corporate secretarial expertise — delivers practical, realistically priced solutions tailored to your objectives.
We are mindful that our professional reputation rests on the quality of our work. That is why the selection of our people, and the rigour we apply on every engagement, remain central to how we operate.
Why international clients work with us
One advisory relationship covering Nigeria's key commercial centres and its oil & gas region.
In our clients' words
They took our audit seriously as a piece of work, not a formality. The partner knew our numbers before the fieldwork started, and the questions we got were the ones that mattered.
We set up in Lagos from London with no local finance team. Tax, incorporation and the company secretarial work all came through one relationship, and replies arrived the same working day.

A firm built on judgement, not templates
Our Firm
Tamuno George & Co. is a firm of Chartered Accountants founded by Tamuno Nathan George — a Chartered Accountant, Chartered Secretary, Barrister, and banker. The firm was registered in 1980 under Nigeria's Registration of Business Names Act 1961 and commenced practice in 1982.
The firm is registered with the Financial Reporting Council (FRC) of Nigeria under FRC/2024/COY/144640.
We offer pragmatic finance and management solutions to large and medium-sized organisations, government agencies, and private investors — including a growing number of international and diaspora clients — drawing on the breadth of experience across our team.
Our affiliated legal practice, Tamuno George Chambers, gives clients integrated access to legal counsel alongside accounting and tax advice, providing necessary legal support whenever the need arises — a single point of contact for complex, cross-disciplinary matters.
Our Strengths
Our firm's success rests on two key resources:
A team of experienced, highly capable professionals with expertise spanning the major sectors of the Nigerian economy.
Modern, computerised systems and processes that allow us to respond quickly and accurately to client needs — wherever in the world our clients are based.
Where We Operate
Tamuno George & Co. is headquartered in Ikoyi, Lagos — Nigeria's commercial and financial hub, close to Victoria Island — with branch offices in Port Harcourt (Rivers State) and a presence in Bayelsa State. This gives clients national reach with the responsiveness of a boutique firm, and for international clients, a single advisory relationship that covers Nigeria's key commercial centres and oil & gas region.
Support at every stage of your presence in Nigeria
We provide an integrated suite of services designed to support your business at every stage of its presence in Nigeria — from market entry through to ongoing compliance and growth.
Taxation Services
Our firm provides a full range of taxation services, supported by the legal expertise of our affiliated chambers. We help clients plan effectively and keep tax liabilities to the minimum permitted by law. For foreign businesses in particular, we provide clear, jargon-free guidance through Nigeria's tax regime. Our taxation services include:
- Companies income tax computation, filing and administration
- Pay-As-You-Earn (PAYE) operation and returns
- Support and advice during tax authority investigations
- Value Added Tax (VAT) compliance and returns
- Property tax advisory and returns
- General tax planning advice
Audit Services and Approach
Our audit approach is tailored to each client's business, not applied as a generic template. Before any audit begins, we hold a pre-audit meeting to agree the approach, timetable, scope and fees, and to understand the client's performance over the year, any constraints affecting their objectives, and management's plans for the period ahead.
Our preparatory work typically includes a visit to the client's premises, discussions with key management to identify specific areas of audit focus, and the preparation of a formal audit planning memorandum — an approach that has consistently supported efficient, well-targeted audits.
Our Managing Partner is involved from the outset of every audit, shaping the strategy based on his understanding of the client's business and extensive professional experience. From there, a detailed audit plan is developed and discussed with the full engagement team.
We maintain a continuous relationship with client management throughout the year, not only during the audit period, which helps us stay closely attuned to the business and respond to its evolving needs. Beyond the audit itself, we also provide practical advisory input, including:
- Identifying opportunities to improve operational efficiency
- Identifying opportunities to improve profitability
- Advising on appropriate business controls
- Reviewing computer systems, including controls, security and data analysis
- Keeping clients informed of relevant developments in business law
