In a significant judgment with wide-ranging implications for Nigeria's upstream petroleum sector, the Tax Appeal Tribunal (Lagos Zone) delivered a split decision in CNOOC Exploration and Production Nigeria Limited v. Federal Inland Revenue Service (Appeal No: TAT/LZ/SD/042/2024), partially setting aside the Federal Inland Revenue Service's (FIRS) stamp duty assessment of USD 214,469,303.42 against the oil and gas major while affirming key aspects of the Revenue Service's position. The decision addresses fundamental questions regarding the characterization of Production Sharing (PSC) interests for stamp duty purposes, the territorial reach of the Stamp Duties Act (SDA), the applicability of limitation periods to tax assessments, and the proper statutory regime for imposing penalties and interest.
Legal Principles Reinforced
1. Substance over Form: Tax authorities are entitled to look beyond the nomenclature of a transaction to its true legal and economic substance. The characterisation of an instrument for stamp duty purposes depends on what it effects, not what it is called.
2. Broad Conception of Property: “Property” for stamp duty purposes extends beyond tangible assets to encompass enforceable rights, including contractual rights and choses in action. PSC participatory rights, being valuable, definable and assignable economic interests, constitute proprietary interests capable of transfer.
3. Territorial Scope of Stamp Duties: Instruments executed outside Nigeria are only liable to stamp duty upon first receipt in Nigeria. Given that the SDA provides for physical stamping, the duty becomes payable only when there is clear proof that the document arrived in the country; otherwise, no duty is owed.
4. Limitation Periods and Enforcement: Section 114 of the SDA bars recovery proceedings, not investigations, assessments, or demands. The provision cannot be deployed by a taxpayer who has
initiated proceedings as a sword to defeat an assessment.
5. Statutory Override: Where inconsistencies exist between the SDA and the FIRSEA, the FIRSEA prevails by virtue of section 68 of the FIRSEA.
6. Penalties and Interest Accrue from Due Date: Penalties and interest are statutory consequences of non-compliance and accrue from the date the tax liability becomes due, not from the date of final determination following objection or appeal. For Oil and Gas Companies: This judgment clarifies that PSC participatory rights constitute proprietary interests chargeable to ad valorem stamp duty upon transfer.
