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 New Zealand 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 New Zealand at 39% — 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, New Zealand produces the lower effective burden at 28.1% versus 33.8% in Colombia — a 5.7 percentage-point gap that compounds to roughly $5,721 of additional take-home annually. Colombia's uncapped social-security charge lifts its effective burden above what the bracket schedule alone would imply; New Zealand's contributions are capped, so high earners there pay a lower marginal social rate on income above the cap. Social-security contributions also differ: Colombia charges 8.0% versus 1.4% in New Zealand, 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.

New Zealand offers the Transitional Resident (flat 0% 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. The Transitional Resident runs for up to 4 years from first qualification, giving New Zealand a meaningful medium-term advantage for eligible movers who plan to stay. Eligibility requires 10+ years of prior non-residency in New Zealand — the regime is unavailable to returning nationals and anyone who has held New Zealand tax residency recently. For movers who don't qualify for New Zealand's Transitional Resident, 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, New Zealand edges Colombia by 5.7 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset.
