A registration question, not a tax bill
This tool does not work out how much tax you owe. It answers a narrower and surprisingly common question: must you register as a provisional taxpayer with SARS at all? The distinction matters because provisional status brings extra filing obligations, two payment deadlines a year and the risk of penalties for underestimating. Plenty of people with a small amount of side income worry they have tripped into provisional territory when they have not. The calculator settles it by comparing your non salary taxable income against a single exemption figure.
What counts as non-salary income
The test looks only at taxable income that does not have PAYE deducted at source. Think rental profit from a flat you let, interest and dividends above their own exemptions, freelance or consulting fees, and business profit. Your normal salary, where your employer already withholds PAYE, is deliberately excluded from this calculation, because SARS is already collecting tax on it month by month. The point of provisional tax is to catch the income that would otherwise slip through untaxed until year end.
The exemption that keeps small earners out
Below a threshold of such income, you are not pulled into the provisional net just because you earned a few rands of interest. The figures this calculator applies are an exemption of R30,000 of taxable non salary income if you are under 65, rising to R50,000 from age 65. Cross the line and you must register, sit at or below it and you generally need not on this basis. Those rand thresholds are the numbers to confirm with SARS, though the structure, a flat age based exemption, is settled.
Where you land against the line
Because the rule is a straight comparison, the clearest way to show it is a few examples for someone under 65, whose exemption is R30,000.
| Non-salary taxable income | Against the R30,000 exemption | Provisional taxpayer? |
|---|
Sitting exactly on R30,000 keeps you out, because the rule triggers only when income is strictly above the exemption. Step a single rand higher and you must register. The R60,000 default in the calculator is comfortably over the line, so it returns a clear yes.
A common misunderstanding
People often assume that owning a rental property automatically makes them a provisional taxpayer. It does not. What matters is the taxable profit after deducting bond interest, rates, levies and maintenance. A flat that barely breaks even, or runs at a loss, may produce non salary income well under the exemption, leaving you off the hook for registration. A practical tip: work out the net rental figure first, not the gross rent, before you decide your status, because the deductions can pull you back under the line.
What actually feeds the figure you compare
The income you test against the exemption is taxable income, after the exemptions that apply to each source have already done their work. Interest counts only once it exceeds the annual local interest exemption, the figure this calculator's wider model uses being R23,800 under 65 and a more generous R34,500 from age 65, so older savers can hold a larger interest bearing balance before any of it reaches this test. A taxable capital gain can feed the figure too, since a disposal brings 40 percent of the net gain into taxable income after the annual exclusion, though a one off sale of an asset does not by itself make you a habitual provisional taxpayer. The point is to add up the net, post exemption amounts from each non salary source, not the raw receipts, before judging where you sit against the line. These exemption and inclusion figures are SARS numbers to confirm, but the principle of testing the after exemption total is settled.
I am over 65 with some interest income, am I provisional?
Not necessarily. From age 65 the exemption rises to R50,000, and on top of that older savers get a larger annual interest exemption before interest is even taxable. So a retiree living mostly on a salary or pension with modest interest often stays below the line. Switch the age band in the tool to see your own threshold.
If I must register, what happens next?
You register as a provisional taxpayer with SARS and then make two estimated payments a year, with an optional third top up, on the income that has no PAYE. This status calculator only tells you whether you must register, so once it returns a yes, move to a provisional tax calculator to size the actual payments and note the mid year and year end deadlines.
