The gap is driven by the headline tax structure — no special regime applied. Both countries are indicated in USD at the displayed FX.
Both Czech Republic and Spain 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 24 percentage points above Czech Republic's 23%, 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, Czech Republic produces the lower effective burden at 26.4% versus 38.7% in Spain — a 12.4 percentage-point gap that compounds to roughly $12,384 of additional take-home annually. The 24-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 23% in Czech Republic. Social-security contributions also differ: Czech Republic charges 11.0% 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: Czech Republic's Paušální Daň (Flat Tax for Self-Employed) (6% flat) and Spain's Beckham Law.
For a digital nomad or remote worker on a $100k income, Czech Republic edges Spain by 12.4 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset.
