The gap is driven by the headline tax structure — no special regime applied. Both countries are indicated in USD at the displayed FX.
Both Bulgaria and Netherlands operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Netherlands's top marginal rate of 50% is 40 percentage points above Bulgaria's 10%, 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, Bulgaria produces the lower effective burden at 13.8% versus 34.1% in Netherlands — a 20.3 percentage-point gap that compounds to roughly $20,329 of additional take-home annually. The 40-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 50% in Netherlands but only 10% in Bulgaria. Bulgaria levies a social-security contribution on employment income; Netherlands does not model one in the engine, so the bracket comparison here is relatively clean for Netherlands. 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.

Netherlands offers the 30% Ruling (Expat Scheme) (flat 30% on qualifying income) for qualifying incoming residents; Bulgaria has no equivalent ICP-targeted regime currently modelled — new residents there enter the standard Bulgaria schedule immediately. The 30% Ruling (Expat Scheme) runs for up to 5 years from first qualification, giving Netherlands a meaningful medium-term advantage for eligible movers who plan to stay. For movers who don't qualify for Netherlands's 30% Ruling (Expat Scheme), both countries revert to their default progressive schedules, where Bulgaria's lower top rate still gives it a structural edge.
For a digital nomad or remote worker on a $100k income, Bulgaria edges Netherlands by 20.3 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. The calculus shifts if the 30% Ruling (Expat Scheme) is available: eligible movers may find Netherlands the stronger play once the regime replaces the default schedule.
