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 Bulgaria operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Argentina's top marginal rate of 35% is 25 percentage points above Bulgaria's 10%, making the statutory gap one of the largest variables in this comparison. Bulgaria 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, Bulgaria produces the lower effective burden at 13.8% versus 35.0% in Argentina — a 21.2 percentage-point gap that compounds to roughly $21,206 of additional take-home annually. The 25-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 35% in Argentina but only 10% in Bulgaria. Bulgaria 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.

Neither Argentina nor Bulgaria offers a dedicated special regime for incoming professionals in the Comparely model — both apply their standard schedules to all new residents from day one. Argentina runs a flat 35% rate on all taxable income — simple to model, with no bracket cliff effects at any income level. Bulgaria also uses a flat rate — 10% — so the effective burden tracks the statutory rate closely across income levels. Without regime optionality, the comparison between these two jurisdictions rests entirely on bracket structure, social-security charges, and cost-of-living — digital nomads who qualify for regimes in other countries may find those alternatives more compelling on a pure tax basis.
For a digital nomad or remote worker on a $100k income, Bulgaria edges Argentina by 21.2 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset.
