How to Register a Business in Nigeria 2026 , CAC Registration Guide

Registering a business is the first legal step every Nigerian entrepreneur needs to take. Whether you are launching a side hustle, opening a shop, or building the next big tech startup, the Corporate Affairs Commission (CAC) is the body responsible for all business registrations in Nigeria. Without a CAC certificate, you cannot open a corporate bank account, sign most commercial leases, or bid for government contracts.

This guide walks you through the entire registration process as it stands in 2026 , from choosing the right business structure to collecting your certificate. We cover costs, timelines, required documents, and the post-registration steps that many first-time founders overlook.

Types of Business Registration in Nigeria

Before you start filling forms, you need to decide which business structure suits your situation. CAC offers several options, but the three most common are:

1. Business Name (Sole Proprietorship or Partnership)

This is the simplest and cheapest way to register a business in Nigeria. A Business Name registration is ideal for freelancers, small traders, artisans, and anyone running a one-person operation. If you have a partner, you can also register a partnership under this category.

The key thing to understand is that a Business Name does not create a separate legal entity. You and the business are legally the same thing. This means your personal assets (car, house, savings) can be used to settle business debts if things go wrong.

2. Private Limited Company (LTD)

This is the most popular structure for serious businesses in Nigeria. A Private Limited Company is a separate legal entity from its owners (shareholders). It can own property, enter contracts, sue, and be sued in its own name.

The biggest advantage is limited liability , if the company runs into debt, creditors can only go after the company's assets, not the personal property of the shareholders. Most investors, banks, and large clients prefer to deal with limited companies.

You need a minimum of one shareholder and one director to register a Private Limited Company. The minimum share capital is NGN 100,000, though many businesses register with higher amounts depending on the industry.

3. Company Limited by Guarantee (CLG)

This structure is designed for non-profit organisations, NGOs, clubs, religious bodies, and associations. Instead of share capital, members guarantee a fixed amount (usually NGN 1 , NGN 100) towards the company's debts in the event of winding up.

A CLG cannot distribute profits to its members. All income must be used to further the organisation's objectives. Registration requires approval from the Attorney General of the Federation, which adds time and complexity to the process.

Which One Should You Choose?

If you are just starting out and testing an idea, a Business Name registration is fast and affordable. If you plan to raise funding, hire employees, or take on significant liability, go with a Private Limited Company from the start. Converting from a Business Name to an LTD later is possible but involves additional cost and paperwork.

What You Need Before You Start

Gather these documents and information before you visit the CAC portal. Having everything ready upfront prevents delays and rejected applications.

For Business Name Registration

• Valid government-issued ID , National Identification Number (NIN) slip or card, driver's licence, or international passport. The NIN is now mandatory for all CAC registrations.
• Passport photograph , Recent, clear, white-background photo in JPEG format. CAC may reject photos with coloured backgrounds or poor resolution.
• Proof of address , A utility bill (electricity, water, or waste), bank statement, or tenancy agreement showing your business or residential address. Must be dated within the last three months.
• Proposed business name , Prepare at least two or three alternative names in case your first choice is already taken or too similar to an existing registration.
• Nature of business , A brief description of what the business does. CAC has a list of standard business activity codes to choose from.

For Private Limited Company (LTD)

Everything listed above, plus:

• Memorandum and Articles of Association (Memart) , This is the company's constitution. It defines the company's objectives, share structure, powers of directors, and rules of operation. CAC requires it to be prepared by a legal practitioner.
• Details of shareholders and directors , Full names, addresses, occupations, dates of birth, nationality, and NIN for each person. A company needs at least one shareholder and one director.
• Share capital structure , How many shares the company will issue and at what value. The minimum authorised share capital is NGN 100,000.
• Registered office address , This must be a physical address in Nigeria (not a PO Box). It will appear on your CAC certificate and is the official address for legal correspondence.
• Company secretary details , Optional for small companies, but recommended. The secretary handles compliance filings and annual returns.

Tax Identification Number (TIN)

You will need a TIN for your business. The good news is that CAC now integrates with the Federal Inland Revenue Service (FIRS), so your TIN can be generated automatically during the registration process. You do not need to apply separately unless you want to obtain one in advance.

CAC Online Registration , Step by Step

CAC moved to a fully digital registration system in recent years. All registrations now go through the online portal. Here is the process from start to finish:

Step 1: Create an Account on the CAC Portal

Visit pre.cac.gov.ng and click "Create Account." You will need a valid email address and phone number. Verify your email to activate the account. This is your personal account , you can register multiple businesses under it.

Step 2: Search for Name Availability

Log in and work through to the name search section. Enter your proposed business name and pay the search fee of NGN 500. The system checks the name against all existing registrations in the CAC database.

A name will be rejected if it is:

• Identical or too similar to an existing registered name
• Offensive or misleading
• Contains restricted words like "Federal," "National," "Municipal," or "Government" without approval
• Suggests a connection to the government or a royal household

If your first choice is unavailable, try your alternative names. Many entrepreneurs waste time on names that are already taken, so always have backups ready.

Step 3: Reserve Your Business Name

Once your name passes the availability check, you can reserve it. A reserved name is held for 60 days, giving you time to complete the registration. If you do not complete it within 60 days, the reservation expires and the name becomes available again.

Step 4: Complete the Registration Form

Fill out the registration form with your personal details, business address, nature of business, and (for LTD companies) details of all directors and shareholders. Double-check every field , errors here are the most common cause of rejected applications.

For a Private Limited Company, you will also need to upload the Memart at this stage. The system guides you through the required fields, but the Memart itself must be a properly formatted legal document.

Step 5: Upload Supporting Documents

Upload scanned copies of your ID, passport photograph, proof of address, and (for LTD) the Memart. Files should be in PDF or JPEG format. Keep each file under 2MB. Blurry or illegible uploads are a common reason for delays.

Step 6: Pay the Registration Fee

Pay the registration fee online using a debit card, bank transfer, or USSD. The fee varies by business type (see the cost breakdown below). You will receive a payment receipt and a reference number to track your application.

Step 7: Receive Your Certificate

Once CAC processes your application, your registration certificate is generated digitally and sent to your email. You can also download it from the portal. The certificate contains your RC (Registration Certificate) number, which you will use for all official purposes including opening a bank account.

For Business Names, this typically happens within 2 to 5 business days. For LTD companies, allow 5 to 14 business days.

Registration Costs in 2026

Here is a detailed breakdown of what you should budget for each type of registration:

Business Name Registration Costs

Private Limited Company (LTD) Registration Costs

Companies with share capital above NGN 1,000,000 pay a higher registration fee on a sliding scale. The stamp duty on share capital is calculated at 0.75% of the total authorised share capital, so a company with NGN 10,000,000 share capital would pay NGN 75,000 in stamp duty alone.

How Long Does Registration Take?

Processing times depend on the type of registration, the completeness of your application, and CAC's current workload.

CAC offers expedited processing for an additional fee. This can reduce the timeline for an LTD company to 3 – 5 business days. Ask about this option on the portal or through a registered CAC agent.

The most common causes of delay are name conflicts (your chosen name is too similar to an existing one), incomplete or illegible document uploads, and errors in the registration form. Taking an extra ten minutes to review your application before submitting can save you days of back-and-forth.

Post-Registration Requirements

Getting your CAC certificate is just the beginning. There are several other registrations and permits you need to complete before your business is fully operational.

1. Tax Identification Number (TIN) with FIRS

If your TIN was not generated automatically during CAC registration, visit the FIRS TaxProMax portal to register. You need your TIN to file tax returns, issue official invoices, and deal with government agencies.

2. VAT Registration

If your business turnover exceeds NGN 25,000,000 per year, you are required to register for Value Added Tax with FIRS. Even if your turnover is below this threshold, voluntary registration allows you to claim input VAT on business purchases. Use our Nigeria VAT Calculator to estimate your VAT obligations.

3. State Internal Revenue Service (IRS) Registration

Register with the IRS in the state where your business operates. You will need this for personal income tax (for sole proprietors) or to register as an employer if you have staff. Each state has its own registration process and portal.

4. NSITF Registration

The Nigeria Social Insurance Trust Fund requires all employers with one or more employees to register and contribute 1% of each employee's monthly salary. This provides compensation for employees who suffer workplace injuries or diseases.

5. ITF Registration

Businesses with five or more employees, or a turnover above NGN 50,000,000, must register with the Industrial Training Fund and contribute 1% of annual payroll. The ITF funds vocational training programmes across Nigeria.

6. Business Premises Permit

Most states and local government areas require a business premises permit before you can legally operate from a physical location. The cost varies by state and the size of your premises, typically ranging from NGN 10,000 to NGN 50,000 per year.

7. Open a Business Bank Account

With your CAC certificate, TIN, and valid ID, you can open a corporate bank account. Most Nigerian banks require:

• CAC registration certificate
• Memorandum and Articles of Association (for LTD companies)
• Board resolution authorising account opening (for LTD companies)
• Completed account opening forms
• Valid ID and passport photographs of all signatories
• Proof of business address
• BVN of all signatories

Opening a business bank account separates your personal and business finances, which is critical for bookkeeping, tax compliance, and building credibility with clients and suppliers.

Common Mistakes That Delay Registration

After helping thousands of Nigerian entrepreneurs, these are the mistakes we see most often:

1. Choosing a Name Too Similar to an Existing Business

CAC rejects names that are identical or confusingly similar to existing registrations. Adding "Nigeria" or "and Sons" to an existing name is not enough to make it distinct. Before searching on the portal, do a quick Google search to see if your proposed name is already in use , even if it is not formally registered, CAC may still flag it.

2. Incomplete or Poor-Quality Document Uploads

Blurry passport photos, expired IDs, and utility bills older than three months are common reasons for rejection. Scan your documents at a minimum of 300 DPI and ensure all text is legible. Save files as PDF for documents and JPEG for photographs.

3. Wrong Business Classification

Choosing an incorrect business activity code can create problems down the line, especially if you need sector-specific licences or permits. For example, if you plan to operate a fintech company but classify yourself as "general trading," you may have difficulty obtaining CBN approvals later. Be specific and accurate with your business description.

4. Not Using a Valid Registered Address

CAC requires a physical address in Nigeria , not a PO Box, not a virtual office (unless it provides a physical address), and not a residential address if your local government prohibits home-based businesses. If you work from home, check your local government's rules before using your home address.

5. Ignoring Annual Returns

Many business owners register and then forget about CAC until they need to renew or update something. All registered businesses must file annual returns with CAC. For a Business Name, the annual return fee is NGN 2,000. For an LTD company, it ranges from NGN 5,000 to NGN 10,000 depending on share capital. Failure to file can result in penalties and eventually the striking off of your business from the register.

Do You Need a Lawyer?

The answer depends on what you are registering.

Business Name , Usually DIY

A Business Name registration is straightforward enough for most people to handle themselves through the CAC portal. The forms are simple, the requirements are minimal, and there is no legal document (like a Memart) that requires professional drafting. If you can fill out an online form and upload documents, you can register a Business Name without help.

That said, if you are not comfortable with technology or simply want someone else to handle it, registered CAC agents charge NGN 5,000 – NGN 15,000 to handle the entire process for you. Many accounting firms and business centres offer this service.

Private Limited Company , Recommended

For an LTD registration, using a lawyer is strongly recommended. The Memorandum and Articles of Association is a legal document that governs how your company operates, and CAC requires it to be prepared by a legal practitioner. A poorly drafted Memart can create problems when you want to bring in investors, issue new shares, or resolve disputes between directors.

Expect to pay NGN 20,000 – NGN 50,000 for a lawyer to prepare the Memart and handle the full registration. Some law firms offer fixed-fee packages that include everything from name search to certificate delivery.
