Most of the gap is opened by Ireland's Irish Non-Dom Remittance regime, which displaces the standard schedule. Both countries are indicated in USD at the displayed FX.
Both Argentina and Ireland operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Ireland's top marginal rate of 40% is 5 percentage points above Argentina's 35%, making the statutory gap one of the largest variables in this comparison. Ireland 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, Ireland produces the lower effective burden at 30.4% versus 35.0% in Argentina — a 4.6 percentage-point gap that compounds to roughly $4,638 of additional take-home annually. The 5-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 40% in Ireland but only 35% in Argentina. Ireland 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.

Ireland offers the Irish Non-Dom Remittance (flat 30% 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. For movers who don't qualify for Ireland's Irish Non-Dom Remittance, 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, Ireland edges Argentina by 4.6 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset.
