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 Portugal operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Portugal's top marginal rate of 48% is 20 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, Brazil produces the lower effective burden at 35.5% versus 40.1% in Portugal — a 4.6 percentage-point gap that compounds to roughly $4,555 of additional take-home annually. The 20-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 48% in Portugal but only 28% in Brazil.

Both countries offer dedicated regimes for incoming professionals: Brazil's 10% Foreign Investment Income (10% flat) and Portugal's IFICI (NHR 2.0) (20% flat). On headline rate alone, Brazil's 10% Foreign Investment Income at 10% beats the alternative at 20% — a 10-point advantage before eligibility is considered.
For a digital nomad or remote worker on a $100k income, Brazil edges Portugal by 4.6 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Regime-eligible movers should check whether Portugal's IFICI (NHR 2.0) (20%) outperforms Brazil's default 35.5% effective rate — for qualifying applicants it often does.
