§ 01 · The verdict

South Africa leaves you with $19,922 more per year — a 28.1% net advantage over United Kingdom on a $100,000 gross.

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.
