With one exception (we're looking at you, Mississippi) states require holders to report and deliver unclaimed property on an annual basis. While the deadline in a majority of the states is in the fall (typically October 31 or November 1), there is a substantial minority of states where the reports are due in the Spring,* including Florida, Illinois, Pennsylvania, Tennessee and Vermont. Of course, there is no rest for the weary unclaimed property professional. After getting out the spring reports in May, it will soon be time to get due diligence letters out for the fall reporting cycle.
* Note that the reporting deadlines discussed above are for general corporations. In many states, life insurers have their own reporting deadlines which tend to fall in May.
