The gap is driven by the headline tax structure — no special regime applied. Both countries are indicated in USD at the displayed FX.
Both Brazil and Mexico operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Mexico's top marginal rate of 35% is 7 percentage points above Brazil's 28%, making the statutory gap one of the largest variables in this comparison.

On a $100k single-resident employment profile under each country's default schedule, Mexico produces the lower effective burden at 30.4% versus 35.5% in Brazil — a 5.2 percentage-point gap that compounds to roughly $5,164 of additional take-home annually. The 7-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 35% in Mexico but only 28% in Brazil. Social-security contributions also differ: Brazil charges 11.0% versus 4.1% in Mexico, adding a second layer to the effective-rate spread that doesn't show in the income-tax brackets alone. The gap widens at higher incomes as marginal rates diverge further; remote workers earning above $150k or $200k should run the full engine scenario with their actual figures for a more precise read.

Both countries offer dedicated regimes for incoming professionals: Brazil's 10% Foreign Investment Income (10% flat) and Mexico's RESICO (Simplified Regime) (2% flat). On headline rate alone, Mexico's RESICO (Simplified Regime) at 2% beats the alternative at 10% — a 8-point advantage before eligibility is considered.
For a digital nomad or remote worker on a $100k income, Mexico edges Brazil by 5.2 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Regime-eligible movers should check whether Brazil's 10% Foreign Investment Income (10%) outperforms Mexico's default 30.4% effective rate — for qualifying applicants it often does.
