The gap is driven by the headline tax structure — no special regime applied. Both countries are indicated in USD at the displayed FX.
Bulgaria taxes residents on worldwide income, while Panama uses a territorial system — only locally-sourced income enters the tax base — a structural difference that shapes how each country treats foreign-source income. Panama's top marginal rate of 25% is 15 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 28.1% in Panama — a 14.3 percentage-point gap that compounds to roughly $14,306 of additional take-home annually. The 15-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 25% in Panama but only 10% in Bulgaria. Social-security contributions also differ: Bulgaria charges 13.8% versus 9.8% in Panama, 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 Panama 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. Panama runs a 3-bracket progressive schedule with a top rate of 25%; 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 Panama by 14.3 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. Panama's territorial system means foreign-source income stays off the resident tax base entirely — a structural advantage for nomads paid by overseas clients that no rate comparison fully captures.
