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 Spain operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Spain's top marginal rate of 47% is 19 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 38.7% in Spain — a 3.2 percentage-point gap that compounds to roughly $3,211 of additional take-home annually. The 19-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 47% in Spain but only 28% in Brazil. Social-security contributions also differ: Brazil charges 11.0% versus 6.3% in Spain, adding a second layer to the effective-rate spread that doesn't show in the income-tax brackets alone.

Both countries offer dedicated regimes for incoming professionals: Brazil's 10% Foreign Investment Income (10% flat) and Spain's Beckham Law.
For a digital nomad or remote worker on a $100k income, Brazil edges Spain by 3.2 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset.
