Small Business Tax, Explained: Six Things Every South African Owner Should Understand

Most small business owners do not have a tax problem. They have an information problem.

You started your business because you are good at something. Nobody handed you a manual explaining what SARS expects, when it expects it, and what it costs you when you get it wrong. So tax becomes the thing you deal with once a year, usually in a panic, usually too late to do anything clever about it.

It does not have to work that way. Here are the six areas that matter most, in plain language.

1. Income Tax: your structure decides the rules

How your business is set up changes how it is taxed. This is the first thing to get right, and the most expensive thing to get wrong.

• Sole proprietors and freelancers: your business profit is taxed as part of your personal income, on the individual sliding scale that runs up to 45 percent.
• Private companies: taxed at the corporate rate of 27 percent on taxable income. Qualifying small business corporations may access a lower graduated rate, which is worth checking.
• Taking money out of a company as salary or as dividends carries its own tax consequences, and they are not the same.

Your structure is a tax decision, not just a legal one. If you registered a company because someone told you to and never looked at it again, it is worth a conversation.

2. VAT: the rules changed this year

This is the biggest shift for small business in years, and plenty of owners have missed it.

From 1 April 2026, the compulsory VAT registration threshold rose from R1 million to R2.3 million in taxable supplies over any consecutive 12 month period. The voluntary registration threshold moved from R50 000 to R120 000. The compulsory figure had not been touched since 2009.

What that means in practice:

• Growing businesses now have significantly more runway before VAT registration becomes compulsory.
• If you are already registered and sitting below R2.3 million, deregistration is an option, not an obligation. There are exit VAT consequences, so run the numbers before you apply.
• The threshold works on a rolling 12 months, not your financial year. Watch it monthly as you grow, not at year end.
• Once you cross it, you have 21 business days to apply. Late registration gets backdated, with penalties and interest on VAT you never charged your customers.

The standard VAT rate remains 15 percent.

3. PAYE and UIF: the moment you employ someone

The day you take on your first employee, a new set of obligations starts. Directors drawing a salary count. Part time staff count.

• Register as an employer with SARS.
• Deduct PAYE from salaries and pay it over monthly on an EMP201, due by the 7th of the following month.
• UIF contributions are 1 percent from the employee and 1 percent from the employer.
• Submit EMP501 reconciliations twice a year, at the end of May and the end of October.

Payroll is the area where small errors compound quietly and surface as a large SARS bill eighteen months later.

4. Provisional Tax: paying as you go

If you earn income that does not have PAYE deducted from it, whether that is business profit, freelance work, rental income or investment income above the thresholds, you are likely a provisional taxpayer. Companies are automatically in the system.

Provisional tax is not an extra tax. It is the same income tax, paid in advance so the full bill does not land at once on assessment.

• For a February year end, there are two payments: the first at the end of August and the second at the end of February.
• An optional third top up payment can be made later to reduce interest.
• Payments are based on your estimate of taxable income. Underestimate meaningfully and SARS charges penalties and interest on the shortfall.

The practical fix is boring and it works. Put a percentage of every payment you receive into a separate account and leave it there.

5. Deductible Expenses: what you can actually claim

The general rule is that expenses incurred in the production of income are deductible. Common ones include stock, salaries, business insurance, professional fees, software subscriptions, business travel, marketing, and a home office where it genuinely qualifies.

The rules are rarely the problem. Proof is.

A claim you cannot support is a claim you cannot make. Most of the money business owners lose at tax time is not lost to the rules, it is lost to a missing slip, a personal account doing the work of a business one, and expenses nobody categorised.

6. SARS Compliance: the dates that matter

Missing a deadline is expensive in a way that has nothing to do with how much tax you owe. Administrative non-compliance penalties for outstanding returns run from R250 to R16 000 per month, and can be charged for up to 35 months.

The pattern behind almost every tax problem

Across all six of these areas, the same thing goes wrong.

Business owners rarely walk in with a tax problem. They walk in with a record keeping problem that has quietly become a tax problem. One bank account doing two jobs. Slips in a drawer. Twelve months of expenses that nobody sorted.

By the time it reaches an accountant, the deductions are gone, the estimate is wrong, and the penalty is already running.

Good records are not admin for the sake of admin. They are the cheapest tax planning available to a small business.
