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 Argentina and South Africa operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. South Africa's top marginal rate of 45% is 10 percentage points above Argentina's 35%, making the statutory gap one of the largest variables in this comparison. South Africa uses a fixed 183-day threshold for residency; Argentina relies on a multi-factor test with no single day-count trigger.

On a $100k single-resident employment profile under each country's default schedule, Argentina produces the lower effective burden at 35.0% versus 35.7% in South Africa — a 0.7 percentage-point gap that compounds to roughly $708 of additional take-home annually. The 10-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 45% in South Africa but only 35% in Argentina. The narrow effective-rate gap means the decision between the two countries is unlikely to rest on the default schedule alone — regime availability, cost of living, and social-security treatment will be the tiebreakers.

South Africa offers the Foreign Employment Income Exemption (s10(1)(o)(ii)) (flat 0% on qualifying income) for qualifying incoming residents; Argentina has no equivalent ICP-targeted regime currently modelled — new residents there enter the standard Argentina schedule immediately. For movers who don't qualify for South Africa's Foreign Employment Income Exemption (s10(1)(o)(ii)), both countries revert to their default progressive schedules, where Argentina's lower top rate still gives it a structural edge.
For a digital nomad or remote worker on a $100k income, Argentina edges South Africa by 0.7 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. The calculus shifts if the Foreign Employment Income Exemption (s10(1)(o)(ii)) is available: eligible movers may find South Africa the stronger play once the regime replaces the default schedule.
