Most of the gap is opened by Croatia's Croatia Digital Nomad Visa regime, which displaces the standard schedule. Both countries are indicated in USD at the displayed FX.
Both Spain and Croatia operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Spain's top marginal rate of 47% is 17 percentage points above Croatia's 30%, 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, Spain produces the lower effective burden at 38.7% versus 44.5% in Croatia — a 5.8 percentage-point gap that compounds to roughly $5,776 of additional take-home annually. The 17-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 47% in Spain but only 30% in Croatia. Social-security contributions also differ: Croatia charges 20.0% versus 6.3% in Spain, adding a second layer to the effective-rate spread that doesn't show in the income-tax brackets alone. 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.

Both countries offer dedicated regimes for incoming professionals: Spain's Beckham Law and Croatia's Croatia Digital Nomad Visa (0% flat). Spain's regime runs for 6 years versus 2 in Croatia — a longer runway worth factoring into a multi-year relocation plan.
For a digital nomad or remote worker on a $100k income, Spain edges Croatia by 5.8 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset.
