The gap is driven by the headline tax structure — no special regime applied. Both countries are indicated in USD at the displayed FX.
Both Colombia and Mexico operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Top statutory rates are close — Colombia at 39% vs Mexico at 35% — 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, Mexico produces the lower effective burden at 30.4% versus 33.8% in Colombia — a 3.4 percentage-point gap that compounds to roughly $3,414 of additional take-home annually. Social-security contributions also differ: Colombia charges 8.0% versus 4.1% in Mexico, adding a second layer to the effective-rate spread that doesn't show in the income-tax brackets alone.

Mexico offers the RESICO (Simplified Regime) (flat 2% on qualifying income) for qualifying incoming residents; Colombia has no equivalent ICP-targeted regime currently modelled — new residents there enter the standard Colombia schedule immediately. For movers who don't qualify for Mexico's RESICO (Simplified Regime), both countries revert to their default progressive schedules, where Colombia's lower top rate still gives it a structural edge.
For a digital nomad or remote worker on a $100k income, Mexico edges Colombia by 3.4 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset.
