The gap is driven by the headline tax structure — no special regime applied. Both countries are indicated in USD at the displayed FX.
Both Spain and Netherlands operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Top statutory rates are close — Spain at 47% vs Netherlands at 50% — so the outcome turns on bracket structure, social charges, and available regimes rather than the headline rate alone.

On a $100k single-resident employment profile under each country's default schedule, Netherlands produces the lower effective burden at 34.1% versus 38.7% in Spain — a 4.6 percentage-point gap that compounds to roughly $4,622 of additional take-home annually. Spain 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.

Both countries offer dedicated regimes for incoming professionals: Spain's Beckham Law and Netherlands's 30% Ruling (Expat Scheme) (30% flat). Spain's regime runs for 6 years versus 5 in Netherlands — a longer runway worth factoring into a multi-year relocation plan.
For a digital nomad or remote worker on a $100k income, Netherlands edges Spain by 4.6 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset.
