The gap is driven by the headline tax structure — no special regime applied. Both countries are indicated in USD at the displayed FX.
Both Argentina 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 13 percentage points above Argentina's 35%, making the statutory gap one of the largest variables in this comparison. Portugal uses a fixed 183-day threshold for residency; Argentina 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, Argentina produces the lower effective burden at 35.0% versus 40.1% in Portugal — a 5.1 percentage-point gap that compounds to roughly $5,089 of additional take-home annually. The 13-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 48% in Portugal but only 35% in Argentina. Portugal levies a social-security contribution on employment income; Argentina does not model one in the engine, so the bracket comparison here is relatively clean for Argentina. 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.

Portugal offers the IFICI (NHR 2.0) (flat 20% on qualifying income) for qualifying incoming residents; Argentina has no equivalent ICP-targeted regime currently modelled — new residents there enter the standard Argentina schedule immediately. The IFICI (NHR 2.0) runs for up to 10 years from first qualification, giving Portugal a meaningful medium-term advantage for eligible movers who plan to stay. Eligibility requires 5+ years of prior non-residency in Portugal — the regime is unavailable to returning nationals and anyone who has held Portugal tax residency recently. For movers who don't qualify for Portugal's IFICI (NHR 2.0), both countries revert to their default progressive schedules, where Argentina's lower top rate still gives it a structural edge.
For a digital nomad or remote worker on a $100k income, Argentina edges Portugal by 5.1 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. The calculus shifts if the IFICI (NHR 2.0) is available: eligible movers may find Portugal the stronger play once the regime replaces the default schedule.
