Nigeria has enacted a new tax law linking cryptocurrency transactions to real identities using Tax Identification Numbers (TIN) and National Identification Numbers (NIN). This move aims to make crypto transactions traceable and integrate them into the tax reporting system without altering the blockchain itself. Virtual Asset Service Providers (VASPs) are now required to collect and report customer TIN/NIN, names, and addresses. They must also submit monthly transaction data to tax authorities and report large or suspicious transactions to law enforcement agencies.
