Most of the gap is opened by Japan's Non-Permanent Resident regime, which displaces the standard schedule. Both countries are indicated in USD at the displayed FX.
Both Argentina and Japan operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Japan's top marginal rate of 45% is 10 percentage points above Argentina'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, Argentina produces the lower effective burden at 35.0% versus 36.9% in Japan — a 1.9 percentage-point gap that compounds to roughly $1,853 of additional take-home annually. The 10-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 45% in Japan but only 35% in Argentina. Japan 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 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.

Japan offers the Non-Permanent Resident (flat 0% 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 Non-Permanent Resident runs for up to 5 years from first qualification, giving Japan a meaningful medium-term advantage for eligible movers who plan to stay. For movers who don't qualify for Japan's Non-Permanent Resident, 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 Japan by 1.9 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. The calculus shifts if the Non-Permanent Resident is available: eligible movers may find Japan the stronger play once the regime replaces the default schedule.
