How to Open a Corporate Bank Account in Nigeria After Business Registration

Registering your business with the CAC is the first step. Opening a corporate bank account is the second, and for many Nigerian founders, it turns out to be the more frustrating one.

The process seems like it should be straightforward. You have your CAC documents. You walk into a bank. You open an account. But what most founders encounter is a list of document requirements they were not expecting, multiple branch visits, and requests for documentation that reveals gaps in their registration they did not know existed.

This guide explains exactly what you need, how to prepare, and what to expect so you can get your corporate account open and operational with the least possible friction.

WHY A CORPORATE ACCOUNT MATTERS

Operating from a personal bank account is one of the most common and most damaging compliance failures among Nigerian founders. Clients and institutional partners, especially corporate clients and NGOs, will not make payments to a personal account. Many simply cannot, as their own financial controls require payments to a verified business account in the payee's registered name.

Investors and lenders require a clean separation between personal and business finances before they will consider any funding conversation. A business that has mixed its finances with the founder's personal account has no clean financial history to present.

Grant applications, government tenders, and most formal business opportunities require a corporate account in the company's registered name as a basic qualifying condition.

WHAT DOCUMENTS DO NIGERIAN BANKS REQUIRE?

For a Limited Liability Company:

Certificate of Incorporation from the CAC. Certified True Copy of the Memorandum and Articles of Association (MEMART). CAC Form 1.1 showing directors, shareholders, and registered address. Tax Identification Number (TIN) certificate. Valid means of identification for all directors: international passport, national identity card, or driver's licence. Utility bill or government-issued document confirming the company's registered address dated within the last three months. Board resolution authorising the opening of the account and specifying the authorised signatories. BVN for all signatories.

For a Business Name:

Certificate of Registration from the CAC. CAC Form BN 01 or equivalent. TIN certificate. Valid means of identification for the proprietor. Utility bill for the business or personal address.

THE BOARD RESOLUTION: WHAT IT IS AND WHY IT MATTERS

For Limited Liability Companies, a board resolution is required before a bank will open or operate a corporate account. This is a formal document signed by the directors that authorises the opening of the account with a named bank, specifies which directors or officers are authorised to operate the account, and defines any conditions on account operation such as requiring two signatories for transactions above a certain amount.

For single-director companies, the resolution is straightforward. For companies with multiple directors, ensure the resolution is signed by the required quorum as specified in your MEMART and that it is on the company's letterhead. Some banks require the resolution to be notarised, so confirm with your chosen bank before preparing the document.

CHOOSING YOUR BANK

Before committing to a specific bank, consider which bank your major clients or institutional partners use, which bank your regular vendors use, the quality of the bank's digital banking platform, and the minimum balance requirements and monthly fees.

WHAT TO EXPECT AT THE BRANCH

Most Nigerian banks require at least one in-person branch visit to open a corporate account, even where the initial application is submitted online. Bring originals of all documents as well as photocopies. Bank staff will verify originals and retain photocopies. If any document is missing, they will typically ask you to return rather than proceeding with an incomplete set. Account activation timelines vary from 24 hours to five working days depending on the bank.

COMMON REASONS APPLICATIONS ARE DELAYED OR REJECTED

Your CAC documents do not match. If the name on your TIN certificate differs from the name on your CAC certificate, even by a minor spelling variation, the bank's compliance team will flag it.

The board resolution is missing or incorrectly drafted. This is the single most common cause of delay for LTD applications.

The registered address cannot be verified. If your CAC-registered address is outdated or is a private residence, some banks will request additional documentation.

BVN mismatches. If any signatory's BVN is linked to a different name than their CAC-listed identity, the compliance check will fail.

AFTER THE ACCOUNT IS OPEN

Update all your invoicing, contracts, and payment instructions to reflect the new corporate account details. Register the account on your TaxPro Max profile with FIRS so it is linked to your tax records. Set up internet and mobile banking access immediately. If you are VAT-registered, ensure the account details are correctly reflected in your TaxPro Max VAT filing profile.
