How to Get a TIN in Nigeria (2026)

The Tax Identification question in Nigeria from 1 January 2026 onward has a tidier shape than it had before. Three credentials anchor three routes to a Tax ID, and the route that applies to a given reader is determined by which credential is already in hand.

• The NIN is the route for an individual. Under the Nigeria Tax Administration Act 2025 framework effective 1 January 2026, the National Identification Number serves as the underlying identifier for the individual taxpayer, and the 13-digit Tax ID the Nigeria Revenue Service portal returns against a NIN lookup is the current format.
• The CAC registration number is the route for an entity. For a company under Part A of CAMA 2020 or a business name under Part C registered after 29 June 2020, the TIN is on the CAC certificate at issuance through the CAC-FIRS integration; under the NTAA 2026 framework the CAC number itself may serve as the entity's Tax ID, and the 13-digit Tax ID retrievable at the NRS portal is the explicit format for downstream systems that expect it.
• The legacy JRB portal is the route for pre-NTAA records. Individuals and entities that registered with the Joint Tax Board or FIRS before the NTAA cutover hold a 10-digit TIN that remains valid for verification of historical records; the legacy route at the JRB portal is operational during the transition for records that have not yet migrated to the NRS Rev360 platform.

This article walks each route. It applies to two reader groups: individuals (salaried workers, self-employed, freelancers, diaspora Nigerians) for whom the NIN-as-TIN flow is the canonical 2026 path, and operators of non-CAC-registered entities (legacy partnerships under state Partnership Laws, unregistered associations needing a tax presence, charitable bodies whose Part F certificate carries no TIN value) for whom the manual NRS route applies. Readers holding a CAC certificate for a post-2020 entity will find the entity-side flow walked in fuller detail at the CAC-side article on getting a TIN after CAC registration — that article opens from the assumption that the TIN is already on the certificate and covers the four entity-side edge cases.

The Nigeria Tax Administration Act 2025 and the Nigeria Tax Act 2025, signed by the President on 26 June 2025 and effective from 1 January 2026, consolidated Nigerian federal tax administration into a unified procedural framework. Three pieces of the 2025 reform package touch the Tax ID question directly.

• The Nigeria Revenue Service (Establishment) Act 2025 restructured the Federal Inland Revenue Service as the Nigeria Revenue Service. Same institution, new name. The historic FIRS domain at firs.gov.ng now redirects to the NRS landing page. The legacy TaxProMax filing platform is in transition to the new Rev360 platform.
• The Joint Revenue Board (Establishment) Act 2025 renamed the Joint Tax Board as the Joint Revenue Board and widened its mandate from the prior personal-income-tax coordination role to harmonisation of revenue administration across the federal NRS and the 36 State Internal Revenue Services + the FCT Internal Revenue Service. The historic JTB domain at jtb.gov.ng currently displays JRB branding while the agency operates under the new name.
• The Nigerian Tax ID Portal at taxid.nrs.gov.ng went live on 1 January 2026 (with a mirror at taxid.jrb.gov.ng) as the front end where the NIN-as-TIN and CAC-number-as-TIN flows are operationalised.

The framework's substantive consequence for a reader is the operational push: from 1 January 2026 onward a Nigerian individual or entity without a current Tax ID faces friction at bank-account opening, insurance-policy onboarding, pension contribution, capital-market investment account opening, government-tender bidding, and immigration-permit renewal. The Tax ID is not optional infrastructure if any of these surfaces matter to the reader.

The Tax architecture is structurally different from the architectures the reader may already know from the BVN or CAC clusters. A short parallel makes the difference visible.

The BVN architecture splits by function:

The CAC architecture also splits by function:

In both cases the customer-facing channel is single — the bank counter for a BVN action, the iCRP portal for a CAC action. The Tax architecture is different. The customer-facing channel splits by tax type.

For the reader the practical consequence is to name the tax type before naming the institution. A company's CIT, VAT, or withholding-tax query goes to NRS. An individual's PIT or PAYE query goes to the State IRS where the individual resides — Lagos State Internal Revenue Service (LIRS) for a Lagos-resident salary earner, FCT-IRS for an Abuja resident, Oyo State IRS (OYIRS) for an Ibadan resident, and the equivalent state IRS for any other state. The Tax ID lookup itself goes through the JRB-coordinated portal at the NRS taxid front end. Routing a query to the wrong institution returns 'not in our jurisdiction' rather than 'not found' and is the most common source of compounded confusion for first-time taxpayers.

The canonical 2026 route for an individual taxpayer is the NIN lookup at the Nigerian Tax ID Portal. The flow is short and the portal is free.

1. 1
   Confirm the NIN is live and the biographic fields are clean
2. 2
   Open the Nigerian Tax ID Portal
3. 3
   Choose National Identification Number as the lookup key
4. 4
   Click Retrieve Tax ID and supply the biographic match
5. 5
   Read and save the 13-digit Tax ID

The route is free. The portal does not charge for issuance. The flow typically completes in two to three minutes for a clean NIN match. Where the lookup returns 'not found', the troubleshooting sequence is in the FAQ above; the most common cause is a biographic-field mismatch, and the fix is on the NIN side rather than at the NRS portal.

For an entity registered at the Corporate Affairs Commission, the Tax ID question is operationally bundled into the CAC certificate.

The reader's first check is to open the CAC certificate (the PDF on the iCRP dashboard at icrp.cac.gov.ng) and look for the TIN field. For most Part A companies and Part C business names registered after 29 June 2020 the field is populated at certificate issuance. The value on the certificate is the canonical Tax ID — no further application is needed.

Where the explicit 13-digit Tax ID is required by a downstream system (a bank's KYC desk asking for the format-specific figure, an NRS-side filing that expects the 13-digit format), the portal lookup at the NRS Tax ID portal returns it.

1. 1
   Open the Nigerian Tax ID Portal and click Corporate
2. 2
   Enter the CAC RC or BN number
3. 3
   Click Retrieve Tax ID
4. 4
   For a pre-2020 entity where the lookup fails

The CAC-side article walks the entity-side flow in fuller detail including the four edge cases (pre-2020 registrations, illegible TIN on certificate, Part F trustees, individual-side route). Readers handling a CAC-registered entity Tax ID question should start there.

The third route applies to a narrower reader set: individuals and entities holding a pre-NTAA 10-digit TIN whose record has not yet migrated to the NRS Rev360 platform, and individuals or entities needing to verify a historical tax filing made under the legacy TIN format.

The route walks at the legacy JRB portal at jtb.gov.ng. The portal currently displays JRB branding under transition (the domain has not migrated to a jrb.gov.ng root) and operates the legacy TIN verification flow.

1. 1
   Open the legacy JRB portal
2. 2
   Enter the legacy 10-digit TIN
3. 3
   Confirm the underlying taxpayer record
4. 4
   Where a fresh Tax ID is needed on top of the legacy record

NTAA 2026 implementation rolls out across NRS regions and state IRSes on differing schedules; the central Tax ID infrastructure at taxid.nrs.gov.ng is live, but profile-migration and state-IRS portal updates may lag in particular jurisdictions. Where a legacy TIN record fails to verify cleanly at either portal, the route is a tax-office support ticket through NRS rather than a fresh application that would duplicate the underlying taxpayer record.

The federal tax agencies were renamed under two 2025 establishment Acts that took effect on 1 January 2026.

• The Federal Inland Revenue Service (FIRS) was renamed the Nigeria Revenue Service (NRS) under the Nigeria Revenue Service (Establishment) Act 2025. The institution is the same; the name and the portal branding changed. The historic FIRS domain at firs.gov.ng now redirects to the NRS landing page.
• The Joint Tax Board (JTB) was renamed the Joint Revenue Board (JRB) under the Joint Revenue Board (Establishment) Act 2025. The JRB is the inter-government coordination body across the federal NRS and the state internal revenue services. The historic JTB domain at jtb.gov.ng currently displays JRB branding while operating as the same institution under the new name and a wider statutory mandate.

For the rest of this article the new names — NRS and JRB — are used. Where a pre-2026 event is referenced (for example, the June 2020 CAC-FIRS integration), the historical name is retained because that is what the source records say. The reader who finds an FIRS or JTB reference in a 2026 banking document, tax notice, or employer communication should read it as the same institution under the old name; nothing operational depends on which name appears on the page.

The portals worth bookmarking:

• Nigerian Tax ID Portal — taxid.nrs.gov.ng. The front end for Tax ID lookup and issuance under the NTAA 2026 framework. Mirrored at the JRB sub-domain at taxid.jrb.gov.ng.
• NRS taxpayer self-service — selfservice.nrs.gov.ng. For taxpayers managing filings, payments, and assessments once the Tax ID is in place.
• NRS main portal — www.nrs.gov.ng. The institutional landing page with publications and policy notices.
• JRB main portal — www.jtb.gov.ng. Still on the historic JTB domain at the time of writing, displaying JRB branding.

The Tax ID sits between the NIN or CAC credential and the wider banking, compliance, and government-service picture. Naming the surfaces helps the reader understand why the framework matters operationally.

• Bank-account opening at Tier 2 and Tier 3. Nigerian banks updated their customer-due-diligence screens through Q1 2026 to require the 13-digit Tax ID alongside the BVN and NIN at Tier 2 and Tier 3 onboarding and KYC refresh. Tier 1 accounts continue to operate on the BVN-or-NIN floor.
• Employer PAYE remittance. An employer's monthly remittance to the State Internal Revenue Service reads the employee's Tax ID. New employees in 2026 onwards are typically asked for the 13-digit format at onboarding; existing employees may be asked to backfill against the legacy 10-digit TIN already on file.
• Government-tender bidding. Federal and state procurement systems require the Tax ID and a Tax Clearance Certificate at submission. The CAC certificate alone is insufficient even where the CAC number serves as the entity's Tax ID under NTAA 2026.
• Immigration permit renewal. CERPAC renewal at the Nigeria Immigration Service for expatriate residents reads the Tax ID against the employer's PAYE record.
• Capital-market account opening. A SEC-regulated stockbroker, asset manager, or mutual-fund administrator requires the Tax ID at account opening from January 2026 onward.
• Insurance and pension. NAICOM-regulated insurers and PenCom-regulated pension fund administrators require the Tax ID at policy and contribution onboarding.

The shared pattern is that the Tax ID is the federal identifier the financial-system and government-service surfaces query against. The NIN remains the underlying credential for an individual; the Tax ID is the format these surfaces store and verify against.

The standard portal lookup at taxid.nrs.gov.ng does not charge a fee, so a payment-pending scenario does not typically arise from the Tax ID retrieval itself. Where a payment surfaces in the Tax ID journey it is usually an adjacent step — a state-IRS PIT registration, a TCC application, an NRS-side filing fee for an entity registering for VAT, a stamp-duty payment routed through the NRS portal — that has stuck somewhere between the bank, Remita, and the institution's reconciliation queue.

The diagnostic sequence and recovery flows are walked in the tax payment pending article. The single most useful action when any Remita-routed payment is stuck is to read the Remita Retrieval Reference's true status at remita.net before any re-payment attempt — re-paying before reading the status risks a double debit that takes 7 to 14 working days to reverse.
