What changes at 2,000,000 CZK

2,000,000 CZK is exactly the flat-tax revenue ceiling. Invoicing a single koruna more in 2026 would end flat-tax eligibility for the year, so this is a risky revenue level to choose that regime.
The health-insurance minimum still binds for 80% activities at this revenue, because 50% of profit sits below the 293,802 CZK annual minimum base.
Even at 2,000,000 CZK, no lump-sum category reaches the 1,762,812 CZK taxable base where the 23% rate starts. You would only cross it with low actual expenses.

Cash retained is revenue minus tax and mandatory insurance. It is not profit: real business costs, VAT, and voluntary sickness insurance are not deducted. See the methodology for every assumption.
