Most of the gap is opened by Italy's Regime Impatriati regime, which displaces the standard schedule. Both countries are indicated in USD at the displayed FX.
Both United Kingdom and Italy operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Top statutory rates are close — United Kingdom at 45% vs Italy at 43% — so the outcome turns on bracket structure, social charges, and available regimes rather than the headline rate alone. Italy uses a fixed 183-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 39.7% in Italy — a 10.6 percentage-point gap that compounds to roughly $10,554 of additional take-home annually. 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: United Kingdom's FIG (Foreign Income and Gains) and Italy's Foreign Pensioner 7% (7% flat). Italy's regime runs for 10 years versus 4 in United Kingdom — a longer runway worth factoring into a multi-year relocation plan.
For a digital nomad or remote worker on a $100k income, United Kingdom edges Italy by 10.6 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset.
