When to upgrade to a limited company
Consider a limited company once your business grows, you take on larger contracts, bring in partners or need investors.
Choosing a business name that will be approved
- Make it unique: names too similar to existing businesses are often rejected.
- Avoid restricted words: words like “Bank”, “Insurance” or “Federal” may need special approval.
- Match your activity: a clear name helps customers and speeds up approval.
- Check social handles and domains: make sure you can use the same name online.
- Submit alternatives: prepare two or three options in case your first choice is taken.
Common mistakes that delay registration
- Uploading blurry ID or signature images.
- Entering a residential address that does not match your documents.
- Choosing a vague business description.
- Paying unofficial agents without receipts.
- Not checking the application status regularly on the portal.
Tax basics for small businesses in Nigeria
After registering, learn your tax obligations. Sole proprietors are generally taxed through personal income tax in their state of residence, while limited companies pay companies income tax. Small businesses may qualify for reduced rates or exemptions depending on turnover. Get a Tax Identification Number, keep records of income and expenses, and check the FIRS and your state internal revenue service for current rules.
Building credibility after registration
- Use your registered name on invoices and receipts.
- Open a corporate account and accept payments into it.
- Create a simple website or social media profile with your CAC details.
- Keep professional records to support future loan or grant applications.

How much does it cost to register a business name in Nigeria?
The official fee to register a business name in Nigeria is set by the CAC and can change, so always check the current amount on the official CAC portal. On top of the registration fee, you may pay for name reservation, certified copies and any agent or lawyer you choose to use.
Agents can be helpful if you are busy or unsure, but some charge far more than the official fees. If you use one, ask for a breakdown of costs and official receipts, and make sure the registration is in your own name with your own details.
Budget for ongoing costs too, such as annual returns, a business bank account and any licences your industry needs.
