If you attempt to log in three times in a row using the wrong combination of SE number and TastSelv PIN, your TastSelv PIN will be blocked. After reordering the PIN, it will be reopened, but if there are three failed log-in attempts in a row on the same day again, the PIN will not be reopened upon reordering. You can contact SKAT on tel. 7222 1818 or via SKAT's contact page (by clicking ‘Kontakt' (Contact) at www.skat.dk) in order to have the PIN reopened. SKAT can usually reopen a blocked PIN immediately.
