Every founder who walks into the Corporate Affairs Commission portal for the first time hits the same fork in the road. Do you register as a business name, commonly called a sole proprietorship, or do you go straight for a limited liability company? The form asks you to choose before you have context to choose wisely, and that single decision affects your taxes, your personal risk, and how seriously banks and clients take you for years afterward.
This guide breaks down both structures in plain terms, using real Nigerian costs and scenarios, so you can pick the one that fits where your business actually is, not where you hope it will be someday.
What a Sole Proprietorship Actually Is
A sole proprietorship, registered with CAC as a business name, is the simplest way to formalize a business in Nigeria. You and the business are legally the same entity. There is no separation between your personal bank account and your business, at least not in the eyes of the law, even if you keep them apart in practice.
Registration is fast and cheap. As of 2026, business name registration through CAC costs around ₦10,000 to ₦15,000 when done directly, though many agents charge more for the paperwork and follow up. You typically get your certificate within a few days if your documents are in order.
This structure suits a tailor in Aba running a one person operation, a freelance graphic designer in Ibadan, or a food vendor in Onitsha who wants a proper business name on receipts without the complexity of company law.
What a Limited Liability Company Is
A limited liability company, or Ltd, is registered as a separate legal person under the Companies and Allied Matters Act. The business can own property, sign contracts, sue, and be sued in its own name, independent of the founders. This separation is the entire point of the structure.
Registering a limited company costs more and takes more paperwork. CAC fees start from roughly ₦50,000 depending on your share capital, and most founders pay a lawyer or accredited agent between ₦80,000 and ₦200,000 all in, including professional fees, depending on complexity. You need at least one director and one shareholder, a registered office address, and a memorandum and articles of association.
This structure fits a tech startup in Lagos raising investment, an import and export business in Port Harcourt dealing with large contracts, or any founder planning to bring in partners, apply for grants, or eventually sell equity.
The Core Difference: Liability
This is the single most important distinction, and it is right there in the name.
Under a sole proprietorship, if your business owes money and cannot pay, creditors can pursue your personal assets. Your car, your house, your personal savings account are all fair game if a court rules against your business. There is no legal wall between you and your business debts.
Under a limited company, your personal liability is generally capped at what you invested as share capital. If the company fails and owes ₦5 million to suppliers, your personal house is not automatically on the line, provided you have run the company properly and not used it as a shield for fraud or personal spending disguised as business expenses.
For a business owner selling low risk goods with cash upfront, this distinction may matter less. For anyone taking on loans, signing supplier contracts, or hiring staff, it matters enormously.
Tax Treatment: A Real Difference in Your Pocket
A sole proprietorship's profit is treated as your personal income and taxed under personal income tax rules administered by your state's internal revenue service, LIRS if you are in Lagos. Rates are progressive, and many small operators fall into lower bands, which can actually mean a lighter tax burden in the early years.
A limited company pays Companies Income Tax to the Federal Inland Revenue Service. Small companies with turnover below ₦25 million are currently exempt from Companies Income Tax, and companies with turnover between ₦25 million and ₦100 million pay a reduced rate, while larger companies pay the standard rate. On top of that, a company must file annual returns with FIRS and CAC whether or not it made a profit, and directors face penalties for late filing.
In practice, many founders start as a business name to keep tax filing simple, then convert to a limited company once turnover and risk both grow. CAC allows this conversion, and it is far cheaper than most people assume.
Credibility and Access to Capital
Banks, government contracts, and many corporate clients simply will not deal with a business name. If you want to open a proper corporate account with lending features, apply for a Bank of Industry loan, bid for a government tender, or bring in an investor, you almost always need a registered limited company with a Tax Identification Number and up to date CAC filings.
Fintech partners like Paystack and Flutterwave will onboard both structures for payment collection, but the moment you want a merchant account tied to a company name rather than your personal name, or you want to raise money from angel investors, the limited company becomes close to mandatory.
Which One Should You Choose?
Ask yourself three questions.
First, how much risk does your business carry? A retail shop selling phone accessories in Computer Village carries different risk than a logistics company moving goods across state lines with trucks and drivers who could be involved in an accident.
Second, do you plan to raise outside capital or bring in partners in the next two years? If yes, register a limited company now rather than converting later under pressure from an investor's lawyer.
Third, can you handle the compliance workload? A limited company means annual returns, proper bookkeeping, and often an accountant on retainer, even a part time one. If you are not ready for that discipline, a business name buys you time to formalize without the full weight of company law.
The Bottom Line
Neither structure is universally better. A sole proprietorship gets you registered fast and cheap, ideal for testing an idea or running a low risk, owner operated business. A limited company protects your personal assets, opens doors to funding and larger contracts, and signals seriousness to partners, but it comes with real ongoing obligations.
Many successful Nigerian businesses start as one and graduate to the other. What matters is making the choice with your eyes open, not defaulting to whatever the CAC agent recommends because it is easier for them to process.
