Last updated: September 2026. The difference is registration, not size or sophistication. A formal business is registered with the authorities, pays tax, keeps records and is counted in official statistics. An informal business trades outside that system. Plenty of informal businesses are profitable, long-running and employ people. What they cannot do is access the things that require proof of existence, and that is the real cost of staying informal.
What makes a business formal
A formal enterprise is registered with the Companies and Intellectual Property Commission or operates as a registered sole proprietor for tax purposes, has a tax number and files returns, holds any sector licences required, keeps financial records, and complies with labour law for the people it employs.
That last point matters more than people expect. Employing someone brings obligations regardless of whether the business is registered, so an informal employer is not exempt from labour law, only harder to hold to it.
What the informal sector actually looks like
Street trading, spaza shops, backyard workshops, informal transport, home-based food production, hairdressing, repairs and countless services operate here. It is a substantial part of South African employment, particularly in townships and rural areas, and much of it is genuine entrepreneurship rather than survival activity.
The advantages are real: you can start today, with almost no paperwork or cost, and test whether anyone wants what you sell.
The practical differences
Access to finance. Lenders and funders require registration, tax compliance and records. An informal business with good cash flow and no paperwork will still be declined, because there is no way to verify it.
Who you can sell to. Corporates, government and most established businesses cannot buy from an unregistered supplier. They need an invoice, a tax clearance and a company they can put on a purchase order. Formalising is often what converts a business from serving individuals to serving organisations, which is where the larger and more reliable money is.
Banking. A business bank account requires registration, and trading through a personal account makes it impossible to separate business from personal finances or to prove turnover later.
Legal protection. Registration lets you protect a name and brand, enforce contracts as a business, and limit personal liability through a company structure. An informal trader carries personal liability for everything.
Growth and exit. An informal business generally cannot be sold, because there is nothing to transfer beyond goodwill. A registered business with records has a value.
The costs of formalising, honestly
Registration itself is inexpensive and can be done online. The real costs are the ongoing ones: annual returns, filing tax returns, keeping records, and complying with labour law once you employ people.
There is also an adjustment in how you operate. Income becomes visible and taxable, which for a business previously keeping everything in cash is a genuine change. Small businesses do benefit from turnover tax and small business corporation regimes designed to reduce that burden, and those are worth understanding before assuming the tax cost is prohibitive. Check the current thresholds with the South African Revenue Service.
When to formalise
The usual answer is: when you are turning away work you cannot invoice for, when you need finance to grow, when you want to employ people properly, or when a larger buyer asks for documents you do not have.
The sequence that works is registration first, then a tax number, then a business bank account, then any sector licence. That order matters because each step depends on the one before it.
Support with the process is free. The Small Enterprise Development and Finance Agency, formed in 2024 from the merger of SEDA, SEFA and the Co-operative Banking Development Agency, provides business diagnostics, registration help and planning support at no cost, and administers funding programmes aimed specifically at township and informal businesses.
Frequently asked questions
What is the main difference between formal and informal business?
Registration. A formal business is registered, pays tax and keeps records. An informal one trades outside that system regardless of how large or profitable it is.
Is informal trading illegal?
Not inherently, but specific activities need permits, such as street trading bays and food handling certificates, and income remains taxable once you pass the threshold.
Why does formalising matter for growth?
Because finance, corporate and government customers, business banking and legal protection all require proof the business exists. Informality closes those doors regardless of performance.
What does it cost to formalise?
Registration is inexpensive. The ongoing costs are annual returns, tax filing, record keeping and labour compliance, partly offset by small business tax regimes.
In what order should I do it?
Register the entity, then get a tax number, then open a business bank account, then obtain any sector licence. Each step depends on the previous one.
Is there free help with the process?
Yes. The national small enterprise agency provides registration support, diagnostics and business planning at no charge, alongside funding programmes for township businesses.
