How to Register a Business Name with CAC in Nigeria: Step-by-Step Guide (2026)

If you are starting a business in Nigeria, registering your business name with the Corporate Affairs Commission (CAC) is usually the first formal step. It gives your business a legal identity, lets you open a business bank account, helps customers trust you and unlocks opportunities that informal traders cannot access, such as contracts, funding programmes and payment accounts with providers like Paystack and Flutterwave.

This guide explains exactly how business name registration works, what you need, what it costs, how long it takes, why applications get rejected and what to do once you have your certificate. It is written for sole proprietors, freelancers, online sellers and small partnerships.

What is a business name registration?

A business name registration, sometimes called an enterprise registration, records your trading name with CAC under the Companies and Allied Matters Act 2020 (CAMA). It is designed for one person trading alone or for partners trading together.

The most important thing to understand is what it does not do. A registered business name is not a separate legal entity. In law, you and the business are the same person, so you are personally responsible for the business’s debts and obligations. If you want a structure that separates your personal assets from the business, you need a limited company instead. We compare the two in our guide to business name vs limited company in Nigeria.

Who should register a business name?

• Freelancers, designers, writers, developers and consultants who invoice clients
• Online sellers, fashion brands, food vendors and small shops
• Two or more people trading together as partners
• Anyone who needs a registered business to open a bank account or bid for work
• Founders who want to start simply and upgrade to a company later

What you need before you start

Most of the delay in registrations comes from missing or mismatched information, so prepare these items first:

• Two or three proposed business names, in order of preference, in case your first choice is unavailable
• A description of the business activity, written clearly and not too narrow
• Proprietor details: full names exactly as on your ID, date of birth, nationality, phone number, email and residential address. Partnerships need this for every partner
• A valid government ID. CAC verifies identity details, so have your National Identification Number (NIN) ready and make sure your name and date of birth match across documents
• A recent passport photograph and your signature in a clear digital format
• A business address in Nigeria. It does not have to be a shop; many home-based and online businesses use a residential address

Step-by-step: how to register a business name with CAC

Step 1: Choose a name that will be approved

Your name must be unique and must not be too similar to an existing registered name. CAC can reject names that closely resemble others, names that suggest government affiliation, or names that use restricted words such as “bank”, “insurance” or “chamber of commerce” without the proper approvals. Check the name on the CAC search facility, then also check whether the matching domain name and social media handles are available, so your brand is consistent online.

Step 2: Reserve the name

On the CAC online portal, submit your preferred names for availability. A small reservation fee applies. If the name is available, CAC holds it for you for a limited period while you complete your application, so do not delay after reserving.

Step 3: Fill in the application

Enter your business details, the nature of the business, the business address and the proprietor or partner information. Upload your ID, passport photograph and signature. Double-check every spelling. A mismatch between the name on your ID and the name on the form is one of the commonest causes of queries.

Step 4: Pay the official fees

Pay the registration fee through the portal. The CAC fee for registering a business name has been about ₦10,000 in recent guides, with small payment-gateway charges added. CAC reviews its fee schedule from time to time, and it introduced a revised schedule effective 1 August 2025, so confirm the current amount on the CAC website before you pay. Be careful of anyone who quotes you an official fee far above this without explaining what else they are charging for.

Step 5: Submit and wait for review

After submission, CAC reviews the application. If there is a problem, you will receive a query explaining what to fix. Respond promptly, because delays in answering add directly to your waiting time.

Step 6: Download your certificate

Once approved, you receive your Certificate of Registration and a status report with your registration number. Download and keep both safely; you will need them for your bank, tax registration and contracts.

How long does it take?

Some straightforward applications are approved within a few days, but there is no guaranteed timeline. Processing time depends on CAC’s workload, the accuracy of your application and whether any queries arise. A sensible plan is to allow one to two weeks, and longer if you are registering around public holidays or system downtime.

How much does it cost?

Two kinds of cost exist: the official CAC fees, and any professional fee you pay if you use an agent or consultant. Official fees are modest, while agents charge for preparing documents, handling queries and saving you time. Our own service for business name registration starts from ₦35,000, and the proposal states the exact figure and what it covers before you pay. Whoever you use, ask for official fees to be itemised separately so you can see what goes to CAC.

Common reasons applications are rejected

• The name is too close to an existing one. Adding a word or changing a letter is often not enough
• Restricted or sensitive words used without the required approval
• Mismatched personal details between ID, application and passport photograph
• Unclear or unlawful business activity descriptions
• Unreadable uploads such as blurry ID scans or cropped signatures
• Failure to answer a CAC query within the time allowed

What to do after you register

Your certificate is a starting line, not a finish line. Once you have it:

1. Register for tax. The federal tax authority, formerly FIRS, now operates as the Nigeria Revenue Service (NRS). Ensure your business has a tax identification number and understand which taxes apply to you
2. Open a business bank account in your registered name, which keeps personal and business money separate
3. Set up professional email and a website on your own domain so customers can find and trust you. See our web development and business name registration services if you want help
4. Diarise annual returns. Every registered business name must file annual returns with CAC. Missing them leads to penalties, and in July 2026 reports said CAC had begun a process to strike off about 100,000 non-compliant companies, which shows how seriously enforcement is being taken
5. Check for sector licences. Some activities, such as financial services, food production, education or health, need additional approvals

Should you do it yourself or use an agent?

Doing it yourself is possible and saves professional fees, but it costs time and carries the risk of rejections. An experienced adviser helps when your name is competitive, your details are complicated, you are registering a partnership, or you simply want it done right without spending days on the portal. Whichever route you choose, you should keep your own copies of every document and make sure the registration is in your name, not the agent’s.
