Corporate entities in Nigeria risk severe disruption to their banking relationships and loan facilities when key corporate documents remain unstamped, a compliance oversight that can bring factory financing and working capital lines to an abrupt halt.
Under the Stamp Duties Act, Cap. S8, Laws of the Federation of Nigeria, 2004, specified corporate instruments—including share subscription agreements, board resolutions authorising borrowing, debenture trust deeds, loan agreements, and guarantees—must be duly stamped before they carry legal weight. An unstamped document is generally inadmissible as evidence in Nigerian courts and may be deemed legally ineffective for enforcement purposes.
Banks and other financial institutions operating in Nigeria routinely require stamped corporate documents as a condition precedent to disbursing facilities. When a company presents an unstamped board resolution or loan agreement, the lender may freeze the drawdown until the defect is cured. In factory loan arrangements, where project timelines and equipment procurement schedules are tightly calibrated, such delays can prove costly.
The Federal Inland Revenue Service (FIRS) is the primary authority for administering stamp duties on corporate transactions, while state internal revenue services handle duties on individual instruments. Companies are expected to stamp documents within 30 days of execution to avoid penalties. Late stamping attracts additional duties and interest, and in some cases, criminal liability may arise for deliberate evasion.
For businesses seeking to avoid disruption, tax and legal advisers recommend conducting a periodic audit of all executed corporate documents to confirm stamping compliance. Where unstamped instruments are discovered, the company should promptly approach the relevant stamp duties office for assessment and payment.
The consequences extend beyond loan drawdowns. During due diligence for mergers, acquisitions or equity investments, unstamped documents are a red flag that can delay or derail transactions. Regulatory filings with the Corporate Affairs Commission and other agencies may also be affected.
Companies are advised to integrate stamping into their document execution workflow, ensuring that every material corporate instrument is presented for stamping at or shortly after execution, rather than waiting until a lender or counterparty demands it.
