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.
Italy taxes residents on worldwide income, while Thailand operates on a remittance basis — foreign income is taxed only when brought into the country — a structural difference that shapes how each country treats foreign-source income. Italy's top marginal rate of 43% is 8 percentage points above Thailand's 35%, 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, Thailand produces the lower effective burden at 23.0% versus 39.7% in Italy — a 16.7 percentage-point gap that compounds to roughly $16,710 of additional take-home annually. The 8-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 43% in Italy but only 35% in Thailand. Social-security contributions also differ: Italy charges 9.2% versus 5.0% in Thailand, 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: Italy's Foreign Pensioner 7% (7% flat) and Thailand's Thailand LTR Visa (17% flat). On headline rate alone, Italy's Foreign Pensioner 7% at 7% beats the alternative at 17% — a 10-point advantage before eligibility is considered.
For a digital nomad or remote worker on a $100k income, Thailand edges Italy by 16.7 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Regime-eligible movers should check whether Italy's Foreign Pensioner 7% (7%) outperforms Thailand's default 23.0% effective rate — for qualifying applicants it often does. Italy taxes residents on worldwide income, so the headline effective rate applies to total global earnings — not just locally-sourced pay.
