Introduction
Unclaimed property refers to liabilities recorded on a company’s books that are owed to another party but remain unclaimed or unresolved for a specified period—known as the dormancy period. The company holding the liability (debtor) is commonly referred to as the ‘holder,’ and the party to whom the liability is owed (creditor) is the ‘owner.’
There are more than a hundred categories of unclaimed property. Common examples include uncashed payroll and vendor checks, accounts receivable credit balances, gift cards, refunds, consumer rebates, stock and dividend-related property and unclaimed mineral interests. In essence, any outstanding obligation owed to a third party can become unclaimed property.
Every U.S. jurisdiction has its own unclaimed property laws that dictate when a liability becomes reportable and must be remitted to the state. Dormancy periods vary by state and property type, but most range from three to five years, with payroll items typically requiring one year. The rules for determining which state has jurisdiction were established by the U.S. Supreme Court in Texas v. New Jersey, 379 U.S. 674 (1965). Under this framework, the state with first priority is the owner’s state of last known address. For example, if a payroll check is issued to an employee with an Illinois address, Illinois would be the state with jurisdiction over that check if it remains uncashed. If the address of the owner is unknown, the liability defaults to the holder’s state of domicile. ‘Domicile’ typically means state of incorporation or formation. States have also expanded the concept of ‘unknown address’ to allow the use of estimates to fill gaps in incomplete records during audits or voluntary disclosures, as well as taking claim to foreign-addressed property.
Audit landscape
Unclaimed property has become a significant revenue source for many states. In Delaware, the Delaware Economic and Financial Advisory Council has indicated Fiscal Year 2025 unclaimed property revenues of over $500 million with claim payments at only approximately $130 million. Meanwhile, Illinois’ Treasurer’s Office has reported receiving over $560 million in cash in Fiscal Year 2025, while only paying out approximately $304 million. This persistent gap between collections and payouts underscores why states continue to increase their focus on enforcement.
Because unclaimed property serves as a non‑tax revenue stream, holders have experienced heightened enforcement activity nationwide. Most states rely on third‑party audit firms, oftentimes compensated on a contingency‑fee basis, to conduct examinations. These firms also maintain contracts with multiple states, meaning that once one jurisdiction initiates an audit, others can easily be invited to join.
Although state‑driven triggers are not always transparent, several factors commonly increase the likelihood of an audit:
