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 Croatia operate on a worldwide-income basis, though each country's bracket structure and available regimes produce materially different outcomes. Croatia's top marginal rate of 30% is 20 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 44.5% in Croatia — a 30.7 percentage-point gap that compounds to roughly $30,728 of additional take-home annually. The 20-point spread in top statutory rates is the primary driver; above their respective thresholds, each additional dollar is taxed at 30% in Croatia but only 10% in Bulgaria. Social-security contributions also differ: Croatia charges 20.0% versus 13.8% in Bulgaria, 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.

Croatia offers the Croatia Digital Nomad Visa (flat 0% on qualifying income) for qualifying incoming residents; Bulgaria has no equivalent ICP-targeted regime currently modelled — new residents there enter the standard Bulgaria schedule immediately. The Croatia Digital Nomad Visa runs for up to 2 years from first qualification, giving Croatia a meaningful medium-term advantage for eligible movers who plan to stay. For movers who don't qualify for Croatia's Croatia Digital Nomad Visa, both countries revert to their default progressive schedules, where Bulgaria's lower top rate still gives it a structural edge.
For a digital nomad or remote worker on a $100k income, Bulgaria edges Croatia by 30.7 percentage points on the default schedule — a real but not overwhelming difference that other variables may offset. The calculus shifts if the Croatia Digital Nomad Visa is available: eligible movers may find Croatia the stronger play once the regime replaces the default schedule.
