Nigeria has emerged as the country with the highest potential for crypto activity to contribute to government revenue through tax, according to new analysis from blockchain analytics firm Chainalysis.
The Crypto Tax Report 2026 estimates that crypto could account for 12.31% of Nigeria’s public finances, giving the country the highest potential revenue contribution among the markets analysed. The finding highlights both the scale of crypto activity in Nigeria and the challenge of bringing more transactions into the formal tax system.
Nigeria Recorded $4.4 Billion in Taxable Crypto Activity
Chainalysis estimates that Nigeria recorded about $4.4 billion in taxable crypto activity in 2025. That activity includes realised trading gains, income from crypto-related activities and crypto-denominated payments. The estimate places Nigeria among the countries where digital assets could meaningfully impact government revenue.
The figure also represents a substantial share of Nigeria’s fiscal gap. According to the report, the $4.4 billion estimate was equivalent to more than 38% of Nigeria’s estimated $11.3 billion budget deficit in 2025. That puts Nigeria 12th among the 15 countries ranked for crypto’s potential contribution towards closing fiscal deficits.
Crypto Tax Activity Reached $457 Billion Globally
Nigeria’s position comes against a much larger global market.Chainalysis estimates that global on-chain taxable crypto activity reached $457 billion in 2025. The figure covers several categories of activity. These include realised gains from centralised and decentralised exchanges, income from mining, staking and lending, gambling activity and crypto-denominated payments.
Stablecoin payments made up the largest component at $248.7 billion. Realised trading gains contributed another $127.1 billion, while mining, staking, lending and gambling generated an estimated $81.7 billion.
Why Nigeria Ranks So Highly
Nigeria’s ranking reflects the country’s deep cryptocurrency adoption. The country has developed a large crypto market despite years of regulatory uncertainty. Peer-to-peer trading, in particular, has played an important role in local crypto activity. Chainalysis also points to the difficulty of capturing transactions that happen outside traditional reporting channels.
This includes activity through decentralised exchanges, self-custodial wallets and local peer-to-peer transactions. As a result, the potential tax base is much larger than the activity that governments can easily identify through traditional financial reporting.
Most Crypto Activity May Escape International Reporting
The report also highlights a major limitation facing tax authorities. The OECD’s Crypto-Asset Reporting Framework (CARF) is expected to support international exchanges of crypto transaction information from 2027.
However, Chainalysis estimates that CARF could practically capture only about 14% of the $457 billion in global taxable crypto activity. The remaining 86% includes transactions and activities that can occur outside the reporting systems covered by the framework. For Nigeria, this creates a particular challenge because of the country’s strong peer-to-peer and self-custody markets.
Nigeria Is Tightening Crypto Tax Rules
The Nigerian government has been moving to bring more digital-asset activity into the formal tax system. The Nigeria Revenue Service has introduced administrative guidelines covering the taxation of virtual assets. These rules address areas including crypto transactions, staking, mining, decentralised finance yields and airdrops.
The framework also places compliance obligations on platforms operating within the country’s regulated financial system. The goal is to improve visibility over crypto activity while creating clearer rules for taxation. However, authorities still face a difficult problem. Transactions that move entirely between private wallets or occur through informal channels can remain difficult to identify automatically.
Kenya Also Ranks Among the Global Leaders
Nigeria is not the only African country highlighted in the Chainalysis analysis. Kenya ranked 13th globally, with crypto representing a potential 5.62% of government revenue, according to the report. The difference between the two countries also reflects different approaches to crypto reporting and taxation. Kenya is pursuing a framework that is more closely aligned with CARF, while South Africa has incorporated cryptocurrency into its existing income and capital gains tax framework.
Crypto Tax Revenue Depends on Better Visibility
Nigeria’s 12.31% crypto tax revenue potential should not be interpreted as money the government is guaranteed to collect. Instead, it represents the potential fiscal importance of taxable crypto activity identified by Chainalysis.
Turning that potential into actual revenue depends on whether authorities can identify taxable transactions, enforce compliance and keep businesses and users within the formal financial system. That balance could become increasingly important as Nigeria expands its digital-asset regulatory framework.

Editorial Takeaway
The Chainalysis ranking shows how significant cryptocurrency has become within Nigeria’s broader financial system.With billions of dollars in estimated taxable activity, crypto is no longer only a regulatory issue. It is also becoming a potential source of government revenue.
The challenge is closing the gap between crypto activity that exists and crypto activity that authorities can effectively tax. As international reporting rules take effect and Nigeria strengthens its domestic framework, that gap could become one of the country’s biggest digital-asset policy questions.
