Late payment interest in Czech Republic 11,75% (8% plus repo rate).
In CZ late payment interest is calculated from the amount of the tax overdue. The rate is 8% plus the repo rate of the Czech National Bank effective on the first day of the calendar half-year when the default took place (repo rate as of 1 January 2022 is 3,75%). The interest arises from the fourth day after the due date until the tax was paid.
