Unclaimed property reports are generally due to Connecticut on March 31, ninety (90) days after the close of the calendar year. Connecticut requires that the reports be received in their unclaimed property offices by this day, in order for the reports to be filed timely.
In 2013, March 31 falls on a Sunday. Furthermore, March 29, the preceding business day, is a state holiday as they observe Good Friday. As such, this year's report is due on March 28, 2013.
