Mississippi

Mississippi’s unclaimed property program is governed by the Uniform Disposition of Unclaimed Property Act and administered by the Mississippi State Treasury. Whether you’re managing dormant accounts or aging checks, staying compliant means taking a proactive and well-documented approach.

Overview of Mississippi’s Unclaimed Property Law

Mississippi law requires businesses and other organizations, referred to as “holders”, to report and remit unclaimed property after a period of inactivity, known as the dormancy period. The Mississippi Treasurer’s Office receives, safeguards, and attempts to return unclaimed property to its rightful owners.

Common types of reportable property include:

• Checking and savings accounts
• Uncashed checks (payroll, vendor, dividends)
• Insurance benefits
• Customer credit balances
• Safe deposit box contents
• Securities and investment proceeds

Once the dormancy period is met, holders must perform due diligence and submit their reports through Mississippi’s online reporting portal. Learn more in our guide on the escheatment process.

Due Diligence Requirements in Mississippi

Before reporting, Mississippi requires holders to make a good-faith effort to reunite owners with their assets. This due diligence step is essential for minimizing escheatment and ensuring compliance.

Key requirements include:

• Sending a written notice via first-class mail at least 60 days before the report for any property valued over $50
• Notices must include the nature of the property and instructions for reclaiming it
• While not required, additional outreach (email, phone) is encouraged to improve recovery rates and demonstrate proactive escheatment compliance

• Report Period: July 1 - June 30
• Report and Payment Deadline: November 1

Additional requirements include:

• Reports must be filed electronically in NAUPA II format via the Mississippi Unclaimed Property Portal
