Tax League World Cup, Matchday 1: The World Cup Opened With Chaos. The Tax Results Were Just As Brutal.

The Tax League World Cup runs daily during the 2026 FIFA World Cup. Every match gets a tax comparison. Same rules as always: €500K salary benchmark, best available regime, no cherry picking.

Day 1 is done. Some countries won twice. Some lost twice.

June 11, 2026. The biggest World Cup in history kicked off at Estadio Azteca with three red cards, two goals, and a comeback win in Guadalajara. On the pitch, Mexico and South Korea took the points.

Off the pitch? The verdict was just as decisive.

Match 1: Mexico 2 to 0 South Africa

On the pitch: Mexico were ruthless. Quiñones nutmegged the keeper in the 9th minute to score the first goal of the tournament. Jiménez headed in the second in the 67th. South Africa had a player sent off, then conceded two more red cards in a chaotic second half. Three red cards. Two goals. One very happy home crowd.

Off the pitch:

🇲🇽 Mexico: 35% top rate. No special flat tax expat regime. Executives taxed under the standard progressive system with normal treaty relief only. Take home on €500K: around €340K to €350K.

🇿🇦 South Africa: 45% top rate. There is a foreign employment income exemption up to R1.25M per year (around €64K at current rates), but on a €500K salary that covers barely 13% of your income. The remaining 87% gets hit at up to 45%. Take home on €500K: around €295K to €305K.

Tax winner: 🇲🇽 Mexico. By around €45K per year.

South Africa lost on the pitch. They lost off it too. Not a great Tuesday for the Bafana Bafana.

Neither country would beat Portugal though. Just saying. 🇵🇹

Match 2: South Korea 2 to 1 Czechia

On the pitch: Czechia took the lead through a brilliant set piece. Krejčí headed in from a throw in that should be illegal. South Korea refused to panic. Lee Kang-in equalised with a chipped finish that had no right to go in. Then substitute Oh sealed the comeback. South Korea wins 2 to 1. Czechia's set piece genius wasn't enough.

Off the pitch:

🇨🇿 Czechia: Two rate system. 15% up to around €70K, 23% above. No dedicated expat flat tax regime. Straightforward, competitive on headline rate, but no special relief for relocating talent. Take home on €500K: around €335K.

🇰🇷 South Korea: Standard top rate is 49.5%. Brutal. But here's the twist. Foreign employees starting work in Korea by end of 2026 can elect a flat 19% national rate (around 20.9% total) for up to 20 years. No salary cap. For high earners, this completely changes the picture. Take home on €500K with flat tax election: around €395K.

Tax winner: 🇰🇷 South Korea. By around €60K per year.

And here's the headline nobody expected: South Korea's flat tax regime almost matches Portugal's IFICI. At around 20.9% vs Portugal's 20%, it's the closest any country has come in this entire series. The catch? Portugal's regime lasts 10 years and covers foreign income too. South Korea's covers employment income only.

Almost Portugal. Not quite.
