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 United Kingdom operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. United Kingdom's top marginal rate of 45% is 18 percentage points above Brazil's 28%, making the statutory gap one of the largest variables in this comparison. Brazil uses a fixed 184-day threshold for residency; United Kingdom relies on a multi-factor test with no single day-count trigger.

On a $100k single-resident employment profile under each country's default schedule, United Kingdom produces the lower effective burden at 29.2% versus 35.5% in Brazil — a 6.3 percentage-point gap that compounds to roughly $6,350 of additional take-home annually. The 18-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 45% in United Kingdom but only 28% in Brazil. Social-security contributions also differ: Brazil charges 11.0% versus 8.0% in United Kingdom, 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 United Kingdom's FIG (Foreign Income and Gains).
For a digital nomad or remote worker on a $100k income, United Kingdom edges Brazil by 6.3 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset.
