What changes at 2,100,000 CZK

At 2,100,000 CZK you are above the 2,000,000 CZK flat-tax revenue ceiling, so the flat-tax regime is not available in any category. The comparison below is between lump-sum categories only.
The lump-sum allowance no longer scales with revenue here: 60% (capped at 1,200,000 CZK), 40% (capped at 800,000 CZK), 80% (capped at 1,600,000 CZK). Every additional koruna above the cap is fully taxable profit, which is why actual expenses start to matter at this level.
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 2,100,000 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.
