Most of the gap is opened by South Africa's Foreign Employment Income Exemption (s10(1)(o)(ii)) regime, which displaces the standard schedule. Both countries are indicated in USD at the displayed FX.
Both Spain and South Africa operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Top statutory rates are close — Spain at 47% vs South Africa at 45% — so the outcome turns on bracket structure, social charges, and available regimes rather than the headline rate alone.

On a $100k single-resident employment profile under each country's default schedule, South Africa produces the lower effective burden at 35.7% versus 38.7% in Spain — a 3 percentage-point gap that compounds to roughly $3,037 of additional take-home annually. Spain levies a social-security contribution on employment income; South Africa does not model one in the engine, so the bracket comparison here is relatively clean for South Africa.

Both countries offer dedicated regimes for incoming professionals: Spain's Beckham Law and South Africa's Foreign Employment Income Exemption (s10(1)(o)(ii)) (0% flat).
For a digital nomad or remote worker on a $100k income, South Africa edges Spain by 3 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset.
