The gap is driven by the headline tax structure — no special regime applied. Both countries are indicated in USD at the displayed FX.
Both Mexico and New Zealand operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Top statutory rates are close — Mexico at 35% vs New Zealand at 39% — 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, New Zealand produces the lower effective burden at 28.1% versus 30.4% in Mexico — a 2.3 percentage-point gap that compounds to roughly $2,307 of additional take-home annually. Mexico's uncapped social-security charge lifts its effective burden above what the bracket schedule alone would imply; New Zealand's contributions are capped, so high earners there pay a lower marginal social rate on income above the cap.

Both countries offer dedicated regimes for incoming professionals: Mexico's RESICO (Simplified Regime) (2% flat) and New Zealand's Transitional Resident (0% flat). The two regime rates are nearly identical (2% vs 0%), so eligibility criteria and duration will determine which is more accessible rather than the rate itself.
For a digital nomad or remote worker on a $100k income, New Zealand edges Mexico by 2.3 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Regime-eligible movers should check whether Mexico's RESICO (Simplified Regime) (2%) outperforms New Zealand's default 28.1% effective rate — for qualifying applicants it often does.
