Year-over-year comparison
How the 2027 budget affects your tax.
SARS jargon, translated
Which tax bracket are you in?
Drag the slider to your annual income and we will show you exactly how SARS calculates your tax — in plain English.
Where you sit
Your bracket: 31%
You earn between R383 101 and R530 200
SARS says
“R79 998 + 31% of taxable income above R383 100”
“On the R16 900 above R383 100 (up to your R400 000), you pay 31%. That's R5 239.”
What this actually means
You DON'T pay 31% on your whole salary. You pay 18% on the first R245 100, then 26% on the next R138 000, then 31% on the R16 900 above R383 101. Your actual tax rate is 16.85%, not 31%.
