What Is New With Dormancy Period Unclaimed Property in September 2026? Latest state treasury and federal records and Key Takeaways

Compare September 2026 state changes, notice windows, dormancy periods, and the separate federal refund deadline.

No nationwide dormancy-period change took effect in September 2026. The main September development is Arizona's revised definition of unclaimed property, while Florida, Connecticut, Maine, and federal programs have separate 2026 rules or deadlines. A dormancy period is the time property remains inactive before it may be presumed abandoned. Most periods depend on state law and property type; federal agencies operate separate programs and search tools, according to USAGov's unclaimed-money guidance.

What changed in Arizona in September 2026?

Arizona Senate Bill 1336 changes the statutory definition of unclaimed-property "property" effective September 12, 2026. The Arizona Department of Revenue announced the amendment on July 31, making it the clearest September-specific development in the available records. The change does not create one new dormancy period for every asset.

Arizona still applies different periods by property type: one year for wages, three years for demand, savings, and time deposits, and 15 years for traveler's checks, as shown in the Arizona Legislature's statutory schedule. Owners and holders should therefore identify the property category before calculating a deadline. A payroll balance, bank deposit, and traveler's check do not become presumptively abandoned on the same timetable.

How do Florida's 2026 rules affect reporting?

Florida now requires two conditions before property becomes reportable and remittable: the applicable dormancy period must expire, and the holder's required due diligence must fail. This distinction matters because dormancy alone does not complete the reporting process. Florida generally uses a five-year dormancy period for intangible property unless a more specific rule applies.

Demand deposits, savings deposits, and matured time deposits generally reach abandonment after five years without the owner activity listed by statute. For property worth at least $50, holders must send notice 90 to 180 days before reporting. An owner who responds can prevent the property from being transferred to state custody. Florida's searchable database must include identified property worth at least $10, according to the 2026 Chapter 717 provisions.

Connecticut changes when holders must notify owners

Connecticut Public Act 26-94 took effect July 1, 2026. It requires holders to provide notice between July 1 and September 30 of the year in which the property is presumed abandoned.

Mailed notice applies when the property is worth $50 or more. If the owner has consented to email, the holder must send electronic notice regardless of value under Connecticut Public Act 26-94. For owners, this makes late-summer mail and authorized email especially important. For holders, it creates a defined notice window that must be incorporated into the reporting calendar.

Maine's manual limits when gift obligations are reportable

Maine's 2026 reporting manual says gift obligations last active in 2022 or later are not yet reportable. They remain liabilities of the business until redeemed rather than immediately transferring to state custody. Maine is also moving stored-value-obligation reporting to the November 1 cycle, beginning with reports due November 1, 2027.

That is a future reporting-cycle change, not a September 2026 dormancy-period change. Businesses should separate gift and stored-value obligations from other property categories. Applying a general dormancy assumption could cause an early or incorrectly scheduled report.

What owners and holders should do now

Owners should not rely on a single national deadline. A practical check starts with the property type, the state connected to the property, and the date of the last qualifying owner activity.

Holders should document both the dormancy calculation and completed notice attempts. Florida demonstrates why these are separate requirements, while Connecticut shows how the timing and delivery method of notice can also matter.

  • Review recent holder notices before they expire.
  • Respond directly to the holder when the property is still in due diligence.
  • Search the appropriate state treasury or unclaimed-property database after remittance.
  • Check relevant federal programs separately rather than expecting state databases to contain every missing payment.
  • Verify the governing property category before calculating any dormancy period.

Federal tax refunds do not follow state dormancy schedules

Federal tax refunds have their own claim deadlines. The IRS estimated that more than 1.3 million people had approximately $1.2 billion in unclaimed 2022 refunds, but the filing deadline was April 15, 2026.

That deadline has passed. Unclaimed federal refund amounts generally become property of the U.S. Treasury after three years, so state dormancy periods and treasury claim procedures do not extend the federal filing window.
