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 Italy 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 5 percentage points above Italy's 43%, 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, Italy produces the lower effective burden at 39.7% versus 40.1% in Portugal — a 0.4 percentage-point gap that compounds to roughly $350 of additional take-home annually. Portugal's uncapped social-security charge lifts its effective burden above what the bracket schedule alone would imply; Italy's contributions are capped, so high earners there pay a lower marginal social rate on income above the cap. The narrow effective-rate gap means the decision between the two countries is unlikely to rest on the default schedule alone — regime availability, cost of living, and social-security treatment will be the tiebreakers.

Both countries offer dedicated regimes for incoming professionals: Italy's Foreign Pensioner 7% (7% flat) and Portugal's IFICI (NHR 2.0) (20% flat). On headline rate alone, Italy's Foreign Pensioner 7% at 7% beats the alternative at 20% — a 13-point advantage before eligibility is considered.
For a digital nomad or remote worker on a $100k income, Italy edges Portugal by 0.4 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 Italy's default 39.7% effective rate — for qualifying applicants it often does.
