Understanding Stamp Duties under the Nigeria Tax Act, 2025 — What Every Business Owner Should Know

Understanding Stamp Duties under the Nigeria Tax Act, 2025 — What Every Business Owner Should Know

In today’s modern economy, every legal and financial transaction must be properly documented, verified, and authenticated. The Nigeria Tax Act, 2025 (Chapter 5: Taxation of Dutiable Instruments) sets out a comprehensive system that ensures all critical business and financial documents are subject to stamp duties, strengthening both tax collection and legal enforceability.

This chapter defines how duties are imposed, who pays them, and the implications of non-compliance — covering everything from property leases and company shares to promissory notes and digital contracts.

1. What Are Dutiable Instruments?

Under Section 124, dutiable instruments include all formal written documents that record or transfer ownership, rights, or obligations — such as agreements, deeds, bills of exchange, leases, and share certificates. Whether executed in Nigeria or signed abroad but affecting property or businesses in Nigeria, such instruments must be stamped at the applicable rate in the Ninth Schedule.

2. How to Pay Stamp Duty

Section 125 introduces flexible methods for paying and validating stamp duty. Payments can be made using:

  • Physical tax stamps

  • Official machine impressions (dies)

  • Electronic or digital tagging

  • Duty receipts or certificates issued by the tax authority

The Joint Revenue Board (JRB), in partnership with the Nigerian Postal Service (NIPOST), can establish new digital systems for stamp verification — an innovation that supports Nigeria’s move toward electronic governance.

3. When and Who Should Pay?

According to Section 126, every chargeable document must be stamped within 30 days of execution. The responsibility lies with the party gaining benefit or ownership — the buyer, transferee, or lessee — not the person giving up the right.

4. The Legal Importance of Stamping

Failure to comply has serious consequences. Under Section 127, an unstamped document cannot be admitted as evidence in court or arbitration. This rule protects the integrity of Nigeria’s legal and tax systems — ensuring that only properly documented, duty-paid instruments can enforce or defend rights.

5. Instruments That Attract Stamp Duty

Section 128 and beyond expand the scope of dutiable instruments to include:

  • Promissory notes and bills of exchange

  • Contracts for sale or purchase of options

  • Conveyance of property or rights

  • Leases, subleases, and tenancy agreements

  • Share capital issuance and loan capital

  • Transfer of mineral or energy assets

  • Appraisals and valuations of real property

This wide coverage ensures that both corporate and private transactions are captured, creating accountability across all levels of commerce.

6. The Broader Impact

By linking legal enforceability to tax compliance, the Act discourages informal transactions and promotes documentation discipline. It also supports Nigeria’s fiscal modernization through digital stamps and electronic receipts, marking a major shift toward e-taxation and transparent recordkeeping.

7. What Businesses Should Do

Every business — from startups to large corporations — should ensure that their agreements, leases, and capital instruments are duly stamped and recorded. This protects them from legal disputes and penalties while ensuring they meet tax obligations.
