Nigeria: Key Changes to Capital Gains Tax (CGT) under the Nigeria Tax Act (NTA) 2025

Introduction

The Nigeria Tax Act (NTA) 2025 represents the most significant consolidation and modernization of Nigeria’s tax code in decades. Among its fiscal reforms, changes to Capital Gains Tax (CGT) will affect individuals, companies, and cross-border investors — altering rates, widening scope, and refining exemptions and administrative rules.

Rate alignment and progressive treatment

Under prior law, CGT was generally charged at a flat 10% on chargeable gains. The NTA 2025 removes that uniform 10% regime for many taxpayers. For companies, capital gains are now taxed at the standard company tax rate (effectively 30% under the new framework), eliminating the previous arbitrage between trading income and capital gains. For individuals, capital gains are now subject to the progressive personal income tax bands rather than a separate flat CGT rate, which can increase the tax on large gains but also introduces graduated relief for smaller taxpayers. This alignment is intended to promote tax neutrality between forms of income and reduce avoidance strategies that recharacterized trading receipts as capital gains. 

Expanded scope: digital assets and indirect transfers

The NTA expands the taxable base by explicitly capturing gains from disposals of digital and virtual assets (for example, cryptocurrencies and tokens) and by strengthening rules on indirect transfers (including certain off-shore transfers of shares or assets that effectively dispose of Nigerian sources). These changes respond to technological developments and prior tax leakage from asset transfers routed through non-resident vehicles. Taxpayers disposing of crypto, tokenized property, or offshore holdings with a Nigerian nexus should reassess compliance. 

New and clarified exemptions / reliefs

While the NTA broadens CGT’s reach, it also clarifies and (in some cases) expands exemptions and reliefs to protect ordinary taxpayers and facilitate corporate reorganisations. Typical clarifications include exemptions for a taxpayer’s principal private residence (subject to conditions), low-value personal chattels, and reliefs for certain reorganisations and reinvestments designed to support business continuity and encourage productive rollovers. The reform also raised the exemption threshold for compensation on loss of employment in some notices, easing hardship in employment terminations. These carve-outs are important planning tools but often come with strict conditions and documentation requirements. 

Transitional and administrative changes

The NTA harmonises definitions (for example, what constitutes a “Nigerian company”), updates filing and withholding obligations, and enlarges enforcement powers for the revenue authority (now restructured under the broader tax reform package). Guidance published by professional firms indicates that while the Acts are signed, some measures may have delayed commencement or staged implementation (practitioners flagged implementation starting on or after Jan 1, 2026 for certain provisions), so taxpayers should confirm effective dates and transitional rules for transactions straddling the reform. 

Practical implications and planning tips

1. Re-price and reassess pending disposals — companies face materially higher CGT exposures, so M&A pricing, sale agreements. and post-deal structures should be revisited. 
2. Review holdings of digital assets and update reporting — crypto disposals now attract CGT risk. 
3. Use documented rollover/reorganisation reliefs where available — these remain valuable for tax-efficient restructurings. 
4. Confirm effective dates and transitional rules with tax advisers and the tax authority before closing major transactions.
