Whether it's birthdays, holidays or tax deadlines — some appointments come back every year. While missed birthdays may just put you in a bad mood, forgotten tax deadlines can be really expensive. Depending on the type of tax, there are binding deadlines for advance declarations and payments, which companies must comply with. Anyone who does not comply with these risks default interest or penalties. Since deadlines fall on weekends and can be postponed as a result, planning ahead is essential.
