You can formalise a cash trade business for under R1,000 and about three to four weeks of admin, and it unlocks the work informal operators cannot touch: government contracts, formal subcontracts and bankable credit. Roughly 19.5% of all employed South Africans worked in the informal sector in late 2024, and a large share of residential building work is transacted in cash. This guide is the path out, without the sermon.
Why so many stay informal
The informal economy is a survival system, not simply a legal grey area. Many skilled tradespeople operate informally because formalisation feels expensive, bureaucratic and risky. That instinct is not entirely wrong. But the risks of staying informal are real, and they compound.
The real risks of staying cash-only
- No recourse on non-payment. Without a formal contract and a registered business, enforcing payment through the courts or the NHBRC dispute process is much harder.
- No COIDA cover. A worker injured on an informal site cannot claim from the Compensation Fund. You, the operator, carry the liability personally.
- SARS exposure. Cash does not exempt you from income tax. SARS can raise an estimated assessment even without formal books, and penalties and interest compound quickly.
- No government work. Public contracts require CIDB registration, Central Supplier Database (CSD) registration and a valid SARS Tax Compliance Status (TCS) PIN. No registration, no tender.
- No bankable history. Informal operators cannot access trade accounts, materials financing or business loans.
The six-step path
- Register the business. A sole proprietorship costs nothing extra: you trade under your own name and ID number. A (Pty) Ltd costs around R175 via CIPC online and separates personal liability.
- Get a SARS income tax number. Register via SARS eFiling. You only pay income tax on profit above the personal threshold, R99,000 for the 2026/27 year if you are under 65. Qualifying micro businesses on the turnover tax system pay 0% on the first R600,000 of turnover.
- Get a TCS PIN. Once registered and up to date, a Tax Compliance Status PIN generates in minutes on eFiling. Most formal contracts ask for it.
- Register for COIDA. Every business with employees must register with the Compensation Fund via the Department of Employment and Labour. Even sole operators who subcontract need it for the Letter of Good Standing that clients and project managers routinely demand.
- Get CIDB Grade 1. Roughly R450 per class of works, no track record required, just administrative compliance, activated in about 48 hours. It puts you on the register for public contracts up to R500,000 and starts your upgrade clock.
- Register on the CSD. The Central Supplier Database is mandatory for government work. It needs your CIPC registration, SARS number, TCS PIN and a bank letter.
Worked example
A cash plasterer with three years' experience wants to bid on a R200,000 municipal maintenance contract. They: register a sole proprietorship (free, same day); get a SARS income tax number on eFiling (1 to 2 days); generate the TCS PIN; register for COIDA (2 to 3 weeks); register CIDB Grade 1 (about R450, online, 48 hours); and register on the CSD (24 to 72 hours if the documents are right). Total out of pocket: under R1,000. Total time: three to four weeks, mostly waiting on COIDA. The contract they could not legally touch is now biddable.
Common mistakes
- Doing the steps out of order. The CSD needs your SARS number and TCS PIN, so SARS comes before CSD, every time.
- Skipping COIDA because you "only use subbies". Clients ask for the Letter of Good Standing regardless.
- Registering a (Pty) Ltd you do not need yet. A sole proprietorship is free and fine for many small operations; upgrade when liability or clients demand it.
- Going formal and ignoring provisional tax. Once registered, set aside for tax as money comes in, not at filing season.
- Letting compliance lapse. A TCS PIN reflects live status. One missed return and the tender pack fails.
