🇨🇿 Czech Republic — Real Expenses Effective Rate in 2026

What's the effective tax rate under Czech real expenses in 2026?

Roughly 33–43% in zero-expense examples. It bottoms out just under 600,000 CZK of revenue and rises in both directions from there — the minimum insurance bases dominate below that, while above it the fixed 30,840 CZK personal credit shrinks as a share of the bill (and past 1,762,812 CZK the 23% income-tax bracket adds on top). That usually makes it much more expensive than recognized expenses or paušální daň.

Why is it so much higher than recognized expenses?

Because health and social insurance are calculated on your tax base (gross minus expenses), and with real expenses that base only shrinks if you actually spent the money. Recognized expenses give you a flat deduction with no receipts required — pure paper reduction, no cash actually leaves your pocket. Real expenses only help if your genuine, documented costs are large enough to beat that.

When does real expenses actually win?

Only when your documented business costs genuinely exceed the recognized expenses rate of gross income — the same share the recognized-expenses flat rate already gives you for free. For example, with a 60% recognized-expense rate and 1,000,000 CZK revenue, the two methods give the same deduction at exactly 600,000 CZK of real costs; real expenses produce a lower tax base only above that amount.
