How Nigerians Can Retrieve Their Tax ID With NIN or CAC From January 2026

The Joint Revenue Board (JRB) and the Nigerian Revenue Services (NRS) have announced a new online platform called the Nigerian Tax ID Portal, which is scheduled to go live on January 1, 2026.

The portal will allow Nigerians and businesses to retrieve their Tax Identification Number (Tax ID) using existing identity numbers. Individuals will use their National Identification Number (NIN), while registered businesses will use their Corporate Affairs Commission (CAC) registration number.

This update follows earlier guidance that a person’s NIN will now serve as their Tax ID, and a company’s CAC registration number will serve as its tax number under the new system. The change is expected to reduce the stress of having to apply for a separate tax ID for basic services like banking and official documentation.

A Tax ID is a unique number used to identify taxable persons for tax administration in Nigeria.

How to Retrieve Your Tax ID on the Portal (From January 1, 2026)

To retrieve your Tax ID, you will use the Tax ID Portal through either of these addresses: taxidjtb.gov.ng or taxidnrs.gov.ng.

For Individuals (Using NIN)

Visit the portal and click the “Individual” option on the homepage. Select “National Identification Number (NIN),” then enter your 11-digit NIN and click “Retrieve Tax ID.”

After that, enter your first name, last name and date of birth exactly as they appear on your NIMC record, then click “Continue.” Your 13-digit Tax ID should appear on the screen.

For Businesses (Using CAC Number)

Visit the portal and click the “Corporate” option. Select the organisation type that applies to your business, then enter your CAC registration number and click “Retrieve Tax ID.”

Your 13-digit Tax ID should then be displayed.

What Else to Know About the New Tax System

The Tinubu administration has enacted four tax reform laws. Two took effect in June 2025, while two are expected to begin on January 1, 2026.

Despite public debate around the reforms, Taiwo Oyedele, Chairman of the Presidential Committee on Fiscal Policy and Tax Reforms, has said implementation will proceed as scheduled from January 1. He has also argued that the changes are designed to reduce the tax burden across the economy.

Oyedele has said most Nigerian workers will either pay no PAYE tax or pay less under the new framework. He also said most small businesses will be exempt from corporate income tax, VAT and withholding tax, while larger companies may benefit from reduced tax liabilities.

According to him, the bills spent about nine months in the National Assembly, which allowed early preparations, and the government has spent recent months working on system upgrades, capacity building and public sensitisation ahead of the January rollout.
