What is Personal Income Tax in Nigeria?

It is a tax imposed on the income of individuals, families, and trustees, governed by the Personal Income Tax Act (PITA). In 2026, the threshold for tax exemption has been adjusted, meaning individuals earning below ₦800,000 annually are now exempt from PIT. However, they are still required to file a “Nil” return to maintain their Tax Clearance Certificate (TCC).
