What changes at 1,700,000 CZK

At this revenue the flat-tax band depends on your category: 60% and 80% activities stay in Band 2 up to 2,000,000 CZK, while 40% activities have moved to Band 3 at 27,139 CZK per month.
For 80% activities the statutory minimum social-insurance base is higher than 55% of profit, so the 5,005 CZK monthly minimum sets the pension bill rather than your revenue.
