Each state keeps a database that lists people and companies that did not claim money that was legally due. If you need some cash, you and your company may want to check with state taxing authorities to claim money that the state may be holding for you. You can do it online.
The flip side to this statement is that companies must file reports that identify people and entities that are owed money or property and remit the items to the state taxing authority.
This article is about a boon and a "gotcha!" State taxing authorities may grant filing extensions. It is highly unlikely that unclaimed property requirements will not be enforced. It takes time to file these reports.
When your company writes a check to anyone, i.e. an employee, vendor etc., if the person doesn't cash it, you can take the money back into income. Right? WRONG!
