Corporate entities in Nigeria face a significant but often overlooked compliance risk: the failure to stamp corporate documents can lead to the freezing of company bank accounts and factory loan facilities.
The requirement flows from Nigeria's Stamp Duties Act, which mandates that specified corporate instruments bear duly paid stamp duty before they can be recognised for legal and commercial purposes. When a company presents an unstamped document to a financial institution, the bank is within its rights to reject the instrument outright or suspend related facilities until the defect is cured.
Banks and other lenders routinely require stamped board resolutions, loan agreements, deeds of debenture, share transfer forms, and other corporate governance documents as part of their know-your-customer and credit documentation processes. An unstamped document signals non-compliance and creates legal uncertainty, prompting cautious lenders to freeze accounts or withhold loan disbursements.
The practical consequences can be severe. A manufacturing company awaiting disbursement of a factory expansion loan may find funds withheld at the last minute. A business with an active overdraft facility could face a sudden freeze because a stamped board resolution authorising the facility was never obtained. In each case, the disruption stems from a procedural gap that is entirely avoidable.
Beyond banking relationships, unstamped documents carry evidentiary consequences. Under Nigerian law, an unstamped instrument is generally not admissible in civil proceedings. This means a company relying on an unstamped contract or agreement in a dispute may be unable to enforce its rights before a court until the document is stamped and applicable penalties are paid.
The Federal Inland Revenue Service has intensified stamp duty enforcement in recent years, deploying technology to track dutiable instruments and assess compliance. Companies that have historically overlooked stamping obligations are now encountering audits, penalty assessments, and demands for overdue stamp duty with interest.
Remedying the situation involves presenting the unstamped document to the relevant tax authority, paying the outstanding duty along with any penalties, and obtaining the stamp. For companies with multiple unstamped documents spanning several years, the cumulative cost can be substantial.
Tax advisers recommend that businesses conduct regular internal audits of their corporate document repositories, identify all unstamped instruments, and prioritise stamping those that are critical to ongoing banking relationships and credit facilities. Proactive compliance is far less expensive than reacting to a frozen account or a disallowed loan drawdown.
