The gap is driven by the headline tax structure — no special regime applied. Both countries are indicated in USD at the displayed FX.
Both Bulgaria and Colombia operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Colombia's top marginal rate of 39% is 29 percentage points above Bulgaria's 10%, 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, Bulgaria produces the lower effective burden at 13.8% versus 33.8% in Colombia — a 20 percentage-point gap that compounds to roughly $19,991 of additional take-home annually. The 29-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 39% in Colombia but only 10% in Bulgaria. Social-security contributions also differ: Bulgaria charges 13.8% versus 8.0% in Colombia, 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.

Neither Bulgaria nor Colombia offers a dedicated special regime for incoming professionals in the Comparely model — both apply their standard schedules to all new residents from day one. Bulgaria runs a flat 10% rate on all taxable income — simple to model, with no bracket cliff effects at any income level. Colombia runs a 7-bracket progressive schedule with a top rate of 39%; the marginal rate climbs in steps, so the effective burden on a $100k profile stays well below the headline. Without regime optionality, the comparison between these two jurisdictions rests entirely on bracket structure, social-security charges, and cost-of-living — digital nomads who qualify for regimes in other countries may find those alternatives more compelling on a pure tax basis.
For a digital nomad or remote worker on a $100k income, Bulgaria edges Colombia by 20 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset.
