TIN is now Tax ID: what changed and how to switch

Nigeria has replaced the Taxpayer Identification Number (TIN) with a unified, 13-digit Tax ID, live on the NRS and Joint Revenue Board portal since 1 January 2026. For Nigerian companies the Tax ID is linked to the CAC registration number; for individuals, to the NIN. If you hold an old FIRS or JTB TIN, retrieve your Tax ID and use it in its place with banks, customers, counterparties and tax filings.

Is my old TIN still valid? The NRS has named the Tax ID as the single official taxpayer identifier. Some systems may still recognise legacy TINs while records are migrated, but we are not aware of an official NRS statement setting a formal period in which both are valid. In e-invoicing, accredited providers are already advising clients that the Tax ID can be used in place of the Business TIN. Retrieve your Tax ID now and use it going forward; if a bank, customer or agency still asks for your TIN, confirm with them which number they require.

How to retrieve your Tax ID (CAC-registered company)

Open the official portal: taxid.nrs.gov.ng (also available at taxid.jrb.gov.ng).
Click the Corporate tab.
Select your organisation type.
Enter your CAC registration number.
Click Retrieve Tax ID. Your 13-digit Tax ID is displayed.
Send the new Tax ID to your bank, customers and tax advisers, and use it on invoices and filings from now on.

Go to the Nigerian Tax ID Portal →

Individuals: use the Individual tab, select NIN, enter your 11-digit NIN, then your first name, last name and date of birth exactly as held by NIMC.

Foreign companies without a CAC number: non-resident persons register under a separate route on the NRS system, and the exact steps depend on your structure and documents. This is where most foreign companies stall, and it's the process we coordinate for you end to end.

Who needs a non-resident Tax ID in Nigeria?

A foreign company generally needs to register for a Nigerian Tax ID if it:

Has a Nigerian subsidiary, distributor, or local business partner it invoices or is invoiced by
Provides digital services, software, or technical services to customers in Nigeria
Enters into contracts with Nigerian entities that involve payments subject to withholding tax
Otherwise has a taxable economic presence in Nigeria under the Nigeria Tax Act 2025 and the Nigeria Tax Administration Act 2025

If any of these apply, Tax ID registration isn't optional, it formalizes your taxable status with the NRS and is generally a prerequisite for the Nigerian party you work with to pay you without complications.

What Tax ID registration actually triggers

Registering for a Tax ID is the starting point, not the end point. Once registered, a non-resident company typically becomes subject to compliance obligations that may include:

Maintaining accurate and up-to-date books of accounts
Timely submission of tax returns to the NRS
Issuing VAT-compliant invoices bearing the assigned Tax ID in correspondence with the NRS
Filing monthly VAT/WHT returns and annual Companies Income Tax (CIT) returns, where applicable
Notifying the NRS promptly of any change of registered address

Not every registration carries the full set of obligations. Where a non-resident's registration is limited in scope, for example, WHT credit only, capital gains tax only, or an exempt entity, the standard CIT filing and full return obligations above may not apply. This is assessed based on the nature of your Nigerian activity, and where a limited-scope registration applies, it should be confirmed with the NRS in writing so your profile is updated accordingly.

Your Tax ID and withholding tax rate

Tax ID registration has a direct, practical effect on the withholding tax rate applied to payments you receive from Nigerian counterparties:

Without a Nigerian Tax ID, WHT is typically applied at the higher rate of 20%.
With a Nigerian Tax ID, the applicable WHT rate on qualifying payments drops to 10%.
Where a Double Taxation Agreement (DTA) exists between Nigeria and your home country, holding a Tax ID is also what enables you to apply for treaty relief, which can reduce the WHT rate further, subject to competent authority approval.

WHT withheld is advance tax, credited against your eventual CIT liability rather than an additional cost layered on top of it. In short: registering isn't just a compliance formality, it has a direct, quantifiable effect on how much is withheld from your Nigerian income in the first place.

How the registration process works

Document preparation: company and business relationship documentation.
Application submission to the Nigeria Revenue Service via the appropriate registration channel.
NRS review and Tax ID issuance: timelines vary, and having a local coordinator to follow up directly with the NRS materially reduces delays.
Post-registration follow-up: once your Tax ID is issued, you can opt for ongoing monitoring and coordination (e.g. via Rev360, the NRS tax administration platform that replaces TaxPro Max) to stay ahead of e-invoicing, WHT, or filing obligations as they arise, or take no further action if your registration is complete as-is.

Common questions

How long does non-resident Tax ID registration take?

Timelines depend on the NRS's current processing volume and the completeness of submitted documentation. Working with a local coordinator who can follow up directly with the NRS is the single biggest factor in avoiding unnecessary delay.

Does Tax ID registration mean I now owe Nigerian tax?

Not automatically, it formalizes your status so that any tax that is owed (based on your actual Nigerian income and activity) can be properly assessed, filed, and, where applicable, relieved under an existing tax treaty. Some non-resident registrations are limited in scope and may not carry a full Corporate Income Tax filing obligation at all, this depends on the nature of your activity in Nigeria.

Does having a Tax ID actually save me money?

Often, yes. Payments to a non-resident without a Nigerian Tax ID are typically withheld at 20%, versus 10% for a registered Tax ID holder, and where a tax treaty applies between Nigeria and your home country, a Tax ID is what allows you to apply for further relief on that rate.

Can I register without a physical office in Nigeria?

Yes, non-resident registration exists specifically for companies without a Nigerian office or permanent establishment but with a taxable economic presence.
