Joe Adinma & Co., Chartered Accountants was established as an audit practice in 2010. The firm is led by Mr. Joe Adinma FCA, who qualified as a Chartered Accountant in 1996 and has been engaged in the profession for nearly three decades.
We are based in Port Harcourt and serve clients across Rivers State, the Niger Delta, and beyond. Our services span statutory audit, tax compliance, forensic investigation, and the preparation of financial statements in full accordance with International Financial Reporting Standards.
Every engagement is conducted under the ethical framework of the Institute of Chartered Accountants of Nigeria — and reviewed at partner level before delivery.
Joe Adinma & Co. is committed to the following in every engagement.
Our audit opinions and investigative reports are formed on the basis of evidence, without regard to what any party may prefer to hear. Independence is not a policy — it is the foundation upon which the professional value of our work rests.
All client information is treated with strict professional confidentiality, in accordance with ICAN's Rules of Professional Conduct and the terms of our engagement letters. We do not discuss client affairs except within the bounds of our professional mandate.
Every engagement is conducted in accordance with the relevant professional framework: ISA for audit work, IFRS and IFRS for SMEs for financial reporting, and the Nigeria Tax Act 2025 and applicable NRS regulations for tax compliance mandates.
Engagements at this firm are supervised and reviewed at partner level. Our clients are not handed to unqualified staff for core professional work. The partner who signs your report is the partner who directed it.
Financial statements, tax returns, and audit reports operate within defined statutory and commercial timeframes. We manage our engagements to meet those timeframes — without compromising the quality of our work.
We communicate findings, risks, and recommendations in plain language. Where a matter requires a difficult decision, we provide the information necessary to make it — without hedging, and without dressing bad news in reassuring language.
