SARS compliance: the complete tax guide for South African businesses

South African businesses answer to plenty of authorities, but only one of them can help itself to your bank account without first going to court, and that is SARS. The South African Revenue Service administers income tax, VAT, PAYE and a handful of smaller taxes under some of the most powerful collection machinery in the statute book — and unlike a once-off registration, tax compliance is a cadence. Returns fall due every month, every second month, twice a year and once a year, each on its own clock, each with its own penalty for being late.

This guide maps the taxes a typical SA business actually deals with, in the order they tend to matter: what each one is, who has to register, when it’s due, and what it costs when you miss. It’s written for the owner, financial manager or bookkeeper who needs the whole picture on one page — not a deep dive on any single return, but a working map of the lot, current to the 2026 changes that moved several of the thresholds.

The taxes a South African business actually deals with

Most businesses meet SARS through four or five separate taxes, and the confusion is rarely about any single one — it’s about keeping all of them on the same calendar. A company pays income tax on its profits and files an ITR14 once a year; it pays that same tax in advance through provisional tax twice a year; if it has employees it withholds PAYE every month; and once it’s big enough it charges and remits VAT every second month. Each has a different form, a different due date, and a different part of SARS chasing it.

The figure above uses a February year-end, the most common in South Africa. Shift your financial year and the anchors move with it, but the shape holds: a monthly obligation, a bi-monthly one, two or three provisional payments, and the annual return. The rest of this guide takes them one at a time.

Income tax and the ITR14

Every company registered in South Africa pays income tax on its taxable income at a flat rate of 27%(for years of assessment ending on or after 31 March 2023). There’s no sliding scale for an ordinary company — the first rand of taxable profit is taxed at the same rate as the millionth. The return that declares it is the ITR14, and it’s due 12 months after the end of your financial year. A company with a February year-end files by the following February; a June year-end, by the following June. That rolling deadline is exactly why company tax slips through the cracks — it isn’t tied to a national date everyone remembers.

Smaller companies get a genuine break. If yours qualifies as a Small Business Corporation(SBC) — broadly, all shareholders are natural persons, turnover is under R20 million, it isn’t a personal-service provider, and no more than 20% of income is investment income — you pay on a graduated scale instead of the flat 27%, with the first slice taxed at 0%:

Those are the SBC rates for years of assessment ending between April 2026 and March 2027; SARS updates the brackets most years, so check the current table when you file. For a genuinely small, profitable company the saving over the flat 27% is real — but the qualifying conditions are strict, and a single disqualifying shareholder or too much investment income drops you back to the standard rate.

Provisional tax: the one that catches people

Provisional tax isn’t a separate tax — it’s income tax paid in advance, in instalments, so you don’t face one enormous bill at assessment. Every company is automatically a provisional taxpayer. So is every individual earning meaningful income that isn’t salary with PAYE already deducted, which catches most business owners drawing dividends, rent, or director’s income. If your only income is a salary taxed through PAYE, you’re generally out.

There are two compulsory payments and one optional one, all worked off your estimate of the year’s taxable income:

• First payment— within six months of the start of your tax year, so the end of August for a February year-end.
• Second payment— by the last business day of your tax year, the end of February.
• Third payment (voluntary top-up)— the end of September, six months after year-end, to settle any shortfall before interest builds up.

The trap is the estimate. SARS lets you base the first-period estimate on your basic amount— essentially your last assessed taxable income (bumped up 8% a year if that assessment is more than 18 months old). But the second payment is judged against reality. If your taxable income comes in under R1 million and your estimate was below 90% of the actual figure and below the basic amount, or it comes in over R1 million and your estimate was below 80% of actual, SARS levies an underestimation penalty of 20%of the shortfall. Pay the tax itself late and there’s a further 10% penalty on top, plus interest. Provisional tax punishes optimism.

VAT — and the R2.3 million question

Value-added tax is charged at 15%. Ignore anything you read about 15.5% or 16% — those increases were announced in the 2025 Budget and then reversed before they ever took effect, so the rate never actually moved. VAT is the tax businesses most often register for too early or too late, and the 2026 Budget changed the answer.

From 1 April 2026, you must register for VAT once your taxable turnover exceeds R2.3 millionin any consecutive 12 months — up from R1 million, where it had sat for the better part of two decades. That’s a real reprieve for growing firms: many businesses that would have been dragged into VAT at R1 million now sit comfortably below the line. You may still register voluntarily once turnover passes R120,000 (raised from R50,000), which is worth doing mainly if your customers are themselves VAT-registered and you want to claim input VAT on your costs.

Once registered, you file a VAT201. Most businesses fall into Category A or B and file every second month; larger vendors (turnover above R30 million) file monthly. The return and payment are due by the 25th of the month after the tax period if you pay by EFT, or by the last business dayof that month if you file and pay through eFiling. The eFiling extension is free, so there’s no reason not to use it.

PAYE: employees’ tax, every month

The moment you have employees, you withhold employees’ tax (PAYE) from their pay and remit it to SARS, along with the Unemployment Insurance Fund (UIF) and Skills Development Levy (SDL) amounts that ride alongside it. This is the most relentless SARS obligation: the EMP201 declaration and payment are due by the 7th of every month(or the last business day before, if the 7th is a weekend or public holiday). Miss it and penalties and interest attach immediately — you’re remitting money you already deducted from someone else, so SARS is unforgiving about it.

Twice a year you also reconcile, via the EMP501employer reconciliation, which squares what you declared and paid against your employees’ tax certificates (IRP5s). There’s an interim reconciliation around September to October and an annual one from April to the end of May. Get it wrong and your employees can’t file their own returns cleanly, so it isn’t a formality.

One payroll-linked obligation that doesn’t go to SARS at all is COIDA— workplace-injury cover run by the Compensation Fund — which most employers only remember when a tender asks for a Letter of Good Standing.

Turnover tax: the micro-business shortcut

For the smallest businesses, SARS offers an escape hatch. Turnover tax is a single elective tax that replaces income tax, VAT, provisional tax, capital gains tax and dividends tax with one calculation based on turnover rather than profit. From 1 April 2026 you qualify if your annual turnover is R2.3 million or less (up from R1 million), and the first R600,000of turnover is tax-free (up from R335,000). Above that the rate climbs gently — 1%, then 2%, then 3% — on a small sliding scale.

It’s genuinely simpler, but it isn’t always cheaper: because it taxes turnover rather than profit, a low-margin business can pay more under turnover tax than it would on its actual profit. It also excludes most professional- and personal-service businesses. Worth modelling carefully before you elect it, because the election ties you in for a while — not a decision to make on a whim.

The returns and their deadlines

Every SARS return a typical business files, on one page. Dates shift for weekends and public holidays, and the annual ones move with your own financial year-end:

What it costs to miss a deadline

SARS penalties aren’t a slap on the wrist, and they compound. Three regimes do most of the damage:

• Administrative penaltiesfor late or outstanding returns — a fixed monthly amount scaled to the size of the business, from R250 a month for the smallest up to R16,000 a month for the largest, recurring every monththe return stays outstanding, for up to 35 months (longer if SARS doesn’t have your registered address). One forgotten return can quietly rack up tens of thousands of rand.
• The provisional-tax underestimation penalty— 20% of the shortfall if your second estimate came in too low, as above.
• Late-payment penalties and interest— typically a 10% penalty on the amount paid late, plus interest at SARS’s prescribed rate (a little over 10% a year in early 2026, and it tracks the repo rate). Interest runs from the due date until you pay, so a small liability left alone only grows.

None of these require SARS to take you to court. They’re raised administratively, and the onus is on you to notice and dispute them — which is far harder than never triggering them.

Where SA businesses actually get caught out

The misses are rarely exotic. They’re the same handful, repeated across almost every business that hasn’t put a system around them:

• A provisional taxpayer who forgets the August first payment entirely, because nothing external reminds them.
• A company that crosses the VAT threshold mid-year and registers months late, owing output VAT it never charged its customers.
• An EMP201 paid a few days late most months, because the 7th isn’t in anyone’s calendar.
• An ITR14 that slips because “12 months after year-end” isn’t a fixed national date.
• A second provisional estimate lowballed to ease cash flow, triggering the 20% penalty at assessment.
• Old admin penalties silently recurring on a return nobody realised was still outstanding.

Every one of these is a calendar problem before it’s a tax problem. We built a free tool for exactly this — the SARS & compliance deadline calendar generates your dates from your year-end and lets you export them straight into your own calendar, so the 7th and the end of August stop being surprises.

SARS is one of four regulatory regimes, not the only one

SARS is the tax corner of a bigger compliance picture. The same business usually also carries POPIA data-protection duties, B-BBEE scorecard obligations for procurement access, and — if it operates in financial services — FSCA conduct requirements. Four regulators, four rulebooks, four calendars, none of which talk to each other. We’ve mapped how they fit together, and where they intersect, in POPIA vs B-BBEE vs SARS vs FSCA: the South African compliance stack explained. If B-BBEE is on your radar too, B-BBEE levels explained is the companion piece, and the complete POPIA guide covers the data-protection side.

Frequently asked questions

Do I have to register for VAT?

Only once your taxable turnover exceeds R2.3 million in any consecutive 12-month period (from 1 April 2026 — it was R1 million before). Below that you can register voluntarily from R120,000 of turnover, which is mainly worth doing if your customers are VAT-registered and you want to reclaim input VAT on your costs.

What is provisional tax, and do I have to pay it?

It’s income tax paid in advance, in instalments. Every company pays it, and so does any individual with significant income that isn’t already taxed through PAYE — which is most business owners. If your only income is a PAYE salary, you generally don’t.

When is my company’s tax return due?

The ITR14 is due 12 months after your financial year-end — the following February for a February year-end, and so on. It’s a rolling deadline tied to your own cycle, not a fixed national date, which is exactly why it’s easy to miss.

What happens if I miss a SARS deadline?

It depends which one, but expect an administrative penalty (from R250 to R16,000 a month, recurring while the return is outstanding), and for late payments a 10% penalty plus interest from the due date. Penalties are raised administratively — SARS doesn’t need a court — and the onus is on you to dispute them.

Is turnover tax worth it?

Sometimes. It replaces income tax, VAT and provisional tax with one turnover-based calculation for businesses under R2.3 million, and the first R600,000 is tax-free. But because it taxes turnover rather than profit, a low-margin business can end up paying more than it would on its actual profit. Model it before electing.
