Nigeria's tax landscape has undergone significant transformation with the extension of capital gains tax (CGT) to digital and virtual assets. The Finance Act 2023 amended the Capital Gains Tax Act, expressly bringing gains from the disposal of digital assets into the chargeable tax net. The National Tax Authority (NTA) and the Nigeria Tax Administration Act (NTAA) collectively provide the legal architecture underpinning this expansion.
For taxpayers, this means that profits realised from the sale, exchange or transfer of cryptocurrencies such as Bitcoin and Ethereum, non-fungible tokens (NFTs), and other virtual assets now attract CGT at the statutory rate of 10 percent. The charge arises on the difference between the disposal proceeds and the allowable cost of acquisition, net of any permissible incidental expenses.
The Federal Inland Revenue Service (FIRS) is the primary agency responsible for administering and enforcing compliance. Taxpayers are expected to self-assess their gains, maintain adequate records of all digital asset transactions, and remit the tax due within the prescribed filing periods. Failure to comply may attract penalties and interest under the general provisions of the tax administration framework.
A key interpretive challenge lies in the classification of digital assets. The legislation adopts a broad definition, capturing any representation of value that exists in digital form and is capable of being transferred, stored or traded electronically. This sweep includes not only widely traded cryptocurrencies but also tokenised securities, utility tokens and other blockchain-based instruments.
The NTA provides the foundational rules for determining chargeable gains, including the computation of cost bases, the treatment of part-disposals and the rules around connected-party transactions in the digital asset space. The NTAA complements this by establishing the procedural framework for assessment, objection, appeal and enforcement.
Taxpayers who hold digital assets through foreign exchanges or custodial wallets are not exempt. The residency-based taxation model subjects Nigerian residents to CGT on worldwide gains, meaning offshore transactions remain within the FIRS' purview. Double taxation relief may be available where Nigeria has a treaty with the jurisdiction in which any foreign tax has been paid.
Businesses that accept digital assets as payment for goods or services face additional considerations. Where digital assets are received as consideration, the market value at the point of receipt typically forms the disposal proceeds for the counterparty and may also trigger CGT implications for the recipient upon subsequent disposal.
The evolving nature of the digital asset ecosystem means that regulatory guidance is likely to be refined over time. Tax professionals advise individuals and businesses with exposure to digital assets to engage proactively with compliance obligations, maintain transaction records and seek professional advice where the tax treatment is uncertain.
