In recent years, Nigeria’s push toward digital governance and improved revenue administration has brought tax compliance to the forefront of everyday life. What was once seen by many citizens as a concern only for large corporations and established businesses has now become a personal requirement for individuals across different walks of life. Today, a Tax Identification Number, commonly referred to as a Tax ID or TIN, is increasingly required for banking services, employment documentation, access to government interventions, business registration, and participation in public and private sector programs.
DDM NEWS reports that in response to this growing demand and the need to simplify access, the Federal Inland Revenue Service (FIRS) has integrated the National Identification Number (NIN) into its tax administration system. This integration now allows Nigerians to retrieve or confirm their Tax ID using their NIN through an official online portal, eliminating the stress, delays, and middlemen that once characterised the process.
This detailed guide by DDM NEWS explains what a Tax ID is, why it matters, who can use the NIN-based retrieval method, and provides a clear, step-by-step explanation of how Nigerians can obtain their Tax ID online in a matter of minutes.
Understanding the Tax Identification Number (Tax ID)
A Tax Identification Number is a unique number issued by the Federal Inland Revenue Service to individuals and businesses for the purpose of identifying and tracking tax obligations. It serves as a permanent reference in all dealings with tax authorities and is linked to an individual’s or organisation’s tax records throughout their lifetime.
For individuals, a Tax ID is increasingly becoming a basic requirement rather than an optional document. DDM NEWS gathered that banks now request it for certain types of accounts, employers require it during onboarding, and government agencies insist on it before disbursing grants, loans, or social intervention funds. Professionals, freelancers, artisans, and even students applying for some opportunities are also being asked to provide their Tax ID as part of compliance checks.
With Nigeria’s broader digital identity framework anchored on the National Identification Number, the integration of NIN and Tax ID systems is designed to ensure accuracy, reduce duplication, and strengthen transparency in revenue collection.
Who Can Retrieve a Tax ID Using Their NIN?
According to information obtained by DDM NEWS, the NIN-based Tax ID retrieval method is designed specifically for individuals. It is available to:
- Nigerian citizens and legally recognised residents.
- Individuals who possess a valid and active 11-digit NIN.
- Persons whose personal details—such as name and date of birth—match exactly with records held by the National Identity Management Commission (NIMC).
Importantly, you do not need to own a registered business or company to use this method. The process is meant for individuals, including salary earners, self-employed persons, students, and those preparing to engage in formal economic activities for the first time.
What You Need Before You Begin
Before visiting the official FIRS Tax ID portal, DDM NEWS advises that you prepare the following information to avoid errors or delays:
- Your 11-digit National Identification Number.
- The correct spelling of your first and last names as registered with NIMC.
- Your date of birth exactly as captured during NIN enrollment.
- A phone, tablet, or computer with a stable internet connection.
Accuracy is critical. Even a minor mismatch in spelling or date format can prevent the system from retrieving your Tax ID.
Step-by-Step Guide: How to Obtain Your Tax ID Using Your NIN
DDM NEWS outlines the process below in clear and simple steps to help Nigerians complete it without stress:
Step 1: Visit the Official FIRS Tax ID Portal
Open your web browser and go to the official FIRS Tax ID website at https://taxid.firs.gov.ng/. This is the only authorised portal for Tax ID retrieval, and users are advised to avoid unofficial links or third-party websites.
Step 2: Select “Individual”
On the homepage, you will see options tailored to different categories of users. Click on “Individual” to proceed, as the NIN-based method applies to personal Tax IDs, not corporate entities.
Step 3: Choose NIN as Your Retrieval Method
You will be prompted to select a Tax ID retrieval method from a dropdown menu. Choose “NIN” and carefully enter your 11-digit National Identification Number in the space provided.
Step 4: Click “Retrieve Tax ID”
After entering your NIN, click the “Retrieve Tax ID” button. A pop-up window will appear requesting additional personal details for verification purposes.
Step 5: Enter Your Personal Details
Provide your first name, last name, and date of birth exactly as they appear on your NIN record. You will also be required to tick a consent box authorising the system to verify your identity using government databases.
Step 6: Submit Your Request
Once you have confirmed that all details are correct, click the “Submit” button to complete the process.
Step 7: View and Save Your Tax ID
If your information matches FIRS and NIMC records, a confirmation message will appear on your screen, displaying your Tax ID. You can copy the number, take a screenshot, or save it securely for future use.
DDM NEWS confirmed that in most cases, the entire process takes only a few minutes when details are entered correctly.
What to Do If Your Tax ID Does Not Appear
In some cases, users may encounter issues where their Tax ID does not display after submission. DDM NEWS gathered that common reasons include name mismatches, incorrect dates of birth, or incomplete syncing between NIN and tax records.
If this happens, users are advised to double-check their NIN details and try again. If the problem persists, contacting FIRS support or visiting the nearest tax office may be necessary to resolve discrepancies manually.
Why This Matters for Small Businesses and MSMEs
Beyond individual compliance, DDM NEWS notes that the simplified Tax ID process has significant implications for Micro, Small, and Medium Enterprises (MSMEs). Many government-backed loans, grants, and intervention programs now require applicants to provide a valid Tax ID as part of eligibility verification.
Entrepreneurs seeking to open corporate bank accounts, register businesses, bid for contracts, or participate in public tenders will find that having a Tax ID is no longer optional. It serves as proof of formal economic participation and enhances credibility with both government and private sector partners.
