Taxpayers are strongly encouraged to avoid the rush and pay before January 31. Placing payments in a USPS dropbox does not guarantee a postmark for that day and using a bank’s online bill pay could delay payment, both of which could result in additional penalties and interest. If paying on or near the last day, we strongly encourage using our dropbox or paying online.
