The Federal Inland Revenue Service says the National Identification Number issued by the National Identity Management Commission has automatically become the Tax Identification Number for individual Nigerians.

The FIRS further stated that the Corporate Affairs Commission registration number will now serve as official tax number for businesses under the new tax system.

This was disclosed in a public awareness campaign on the new tax laws shared by the Service on X on Monday.

“The Tax ID unifies all Tax Identification Numbers previously issued by the FIRS and State Internal Revenue Services into a single identifier,” the Service said.

“For individuals, your NIN automatically serves as your Tax ID, while for registered companies, your CAC RC number is used. You do not need a physical card, as the Tax ID is a unique number linked directly to your identity.”

The FIRS added that the new system is designed to simplify identification, reduce duplication, close loopholes for tax evasion, and promote fairness by ensuring that everyone who earns taxable income contributes appropriately.

The Service urged the public to disregard misinformation surrounding the reform and assured Nigerians that the new tax framework is aimed at improving efficiency and transparency in tax administration.
