Super-Gross Was Abolished 2021 — Now Standard Calculation
Until 2020, Czech employees were taxed on the 'super-gross' wage (gross + employer's social contributions). The 2021 reform abolished super-gross — now income tax is based on gross salary directly. This simplification raised effective net pay by 7-10% for most workers. The 23% surcharge replaced the previous solidarity tax. Source: Income Tax Act §6.
23% Surcharge Bracket for High Earners
Monthly tax base above CZK 131,901 (36× minimum wage CZK 19,500 in 2027) is taxed at 23%. The threshold is annualized at CZK 1,582,812. High earners benefit from spreading bonuses across years. The surcharge replaces the old 7% solidarity tax. Pension and health insurance also have an income ceiling — pension capped at 48× average wage.
Tax Credits Reduce Final Tax — Not Tax Base
Czech tax credits work like tax CREDITS, not deductions. They reduce the tax owed CZK-for-CZK, not the taxable income. Credits can also turn into tax bonus (refund) for child credit if exceeds tax owed. Most common: basic taxpayer CZK 30,840, child CZK 15,204-27,840, working spouse credit CZK 24,840 (low-income spouse). Disability credit CZK 2,520-5,040.
