Four tax reform laws have been enacted under the Tinubu administration. Two of the laws took effect in June 2025, while two are scheduled for January 1, 2026.

Despite the controversies surrounding the two laws, Chairman of the Presidential Committee on Fiscal Policy and Tax Reforms, Taiwo Oyedele, told journalists on Friday that the implementation will proceed as planned from January 1.

According to Oyedele, the new laws will deliver significant tax relief across the economy.

• He also noted that approximately 97% of small businesses will be exempt from corporate income tax, VAT, and withholding tax, while large companies will benefit from reduced tax liabilities.
• The laws, he said, are intended to promote economic growth, inclusivity, and shared prosperity.
