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 Mexico operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Mexico's top marginal rate of 35% is 12 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 30.4% in Mexico — a 4 percentage-point gap that compounds to roughly $4,009 of additional take-home annually. The 12-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 35% in Mexico but only 23% in Czech Republic. Social-security contributions also differ: Czech Republic charges 11.0% versus 4.1% in Mexico, adding a second layer to the effective-rate spread that doesn't show in the income-tax brackets alone.

Both countries offer dedicated regimes for incoming professionals: Czech Republic's Paušální Daň (Flat Tax for Self-Employed) (6% flat) and Mexico's RESICO (Simplified Regime) (2% flat). On headline rate alone, Mexico's RESICO (Simplified Regime) at 2% beats the alternative at 6% — a 4-point advantage before eligibility is considered.
For a digital nomad or remote worker on a $100k income, Czech Republic edges Mexico by 4 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Regime-eligible movers should check whether Mexico's RESICO (Simplified Regime) (2%) outperforms Czech Republic's default 26.4% effective rate — for qualifying applicants it often does.
