Tax calendar
The dates below are the general dates published by the tax authority. Your own notice wins if it says something else. Income tax withheld from wages is not one of these dates: the employer pays it.
If a date is missing from the alert file, it is not replaced. Your tax notice and the official page give yours.

Questions
Are the online date and the postal date the same?
Often no. Each tax's text repeats both when the source distinguishes them.
Where is the monthly tax payment?
Tax withheld from wages is paid by the employer. It is not one of the deadlines above. For a bill you pay yourself, put the date from your notice on the Fleuris calendar.
