Computed by our open tax engine — assumes no deductible expenses, full-year tax residency. Rules as of Jan 1, 2026.
Modeled with the folded rates the engine needs: social 0.1606 = 29.2% × 55% assessment base, capped at 48× average wage (max levy 686,341.47 = 0.292 × 2,350,416); health 0.0675 = 13.5% × 50% assessment base, no upper cap. The 30,840 CZK annual taxpayer credit (sleva na poplatníka) is modeled as an equivalent 205,600 CZK base allowance (30,840 ÷ 0.15), exact while taxable income stays in the 15% band. In Czechia social and health contributions are NOT deductible from the PIT base (unlike SK/PL), so PIT is levied on the full profit. The 2026 minimum social advance is 5,005 CZK/mo — the minimum assessment base was cut from 40% to 35% of average wage retroactively for the whole of 2026 (lower payments collected from June, January–May overpayments refunded), giving an annual minimum of 60,060 CZK. Real 2026 minimum monthly health advance is 3,306 CZK. First-year and side-activity relief, spouse/child credits, and the paušální-daň alternative are separate schemes/not modeled.
