September 2026 sits inside the annual unclaimed property reporting season, not at its deadline. Most states require holders — the banks, employers, insurers and utilities sitting on your forgotten money — to file their reports and remit the funds by October 31 or November 1, covering property that hit its dormancy period as of June 30, 2026. The Arizona Department of Revenue describes exactly this structure in its reporting requirements guidance, and it is the pattern most fall-filing states share.
What makes September matter is the notice window that closes in it. This is the month when the last "we are about to turn your account over to the state" letters go out, which is why so many people search for answers about annual reports right now. Below are the questions that come up most, answered from state treasury and revenue department sources.

Why a letter arrived in your mailbox this month
Before a holder escheats your property — escheatment is the legal transfer of abandoned funds to state custody — most states require a written attempt to reach you first. That step is called due diligence, and its timing is fixed by statute. Wisconsin, for example, requires holders to mail first-class letters between July 1 and September 1 to owners of property worth $50 or more, unless the last known address is known to be invalid, with the report and remittance due November 1. That schedule appears in the Wisconsin Department of Revenue's Publication 82 holder report guide.
So a September letter is usually the end of the notice period, not the beginning. If you respond before the holder files, the money never leaves the company and you skip the state claims process entirely. If you do nothing, the property goes to the state treasury, where it waits for you — states hold unclaimed property indefinitely in most cases. The practical read: a due diligence letter is the cheapest possible moment to recover your own money. Verify the letter is genuine by contacting the company through a number you look up yourself, not one printed in the notice.
Is November 1 the deadline everywhere?
No, and assuming it is will cause a holder to miss a filing by four months. Texas runs on an entirely different calendar: holders report and remit by July 1, using a March 1 annual cutoff for abandonment periods, and must send due diligence notices no later than 60 days before that July 1 due date. The Texas Comptroller sets this out in its how-to-file instructions for holders. California complicates the picture in a different way, by splitting one filing into two.
The Notice Report is due before November 1 — before May 1 for life insurers — and the Remit Report that actually transfers the property follows the next June 1 through June 15, or December 1 through 15 for life insurers. The California State Controller's Office explains the two-step sequence in its how to report guidance. For owners, that split has a concrete consequence. A California property reported this November will not appear as claimable state-held funds until the following summer. Searching a state database in December and finding nothing does not mean the property was never reported.
How long before property is considered abandoned?
Dormancy periods vary by property type, not only by state, and the spread is wide. Payroll, wages, commissions and utility deposits are generally presumed abandoned after one year. Most other property types — bank accounts, credit balances, insurance proceeds — run three to five years.
Arizona's holder guidance on determining when to report lays out that split. That one-year clock on wages is the detail that surprises people most. A final paycheck from a job left in mid-2025 can already be sitting in a fall 2026 holder report, while a dormant savings account opened the same year has years left to run.
- Uncashed final paycheck or commission: often one year
- Utility security deposit after service ends: often one year
- Checking and savings accounts: typically three to five years
- Insurance and investment proceeds: typically three to five years
What happens to a holder who files late or not at all
The penalties are ordinary state tax penalties, and they stack. Wisconsin assesses a $150 penalty for a late-filed holder report plus a late payment penalty of 15% of the value of the property, and requires all holder reports to be filed electronically. Both figures come from the same Wisconsin Publication 82 guide cited above. Audit exposure is the larger risk, and Delaware has built an explicit fork in the road.
Holders invited to the Secretary of State's Voluntary Disclosure Agreement program on August 14, 2026 may enroll through November 12, 2026; those who do not enroll receive a Notice of Examination from the Office of Unclaimed Property. The state's voluntary disclosure program page records that it issued those examination notices by July 13, 2026 for the earlier April 10, 2026 invitation round. Whether a holder must file anything when it finds no reportable property depends on the state. South Carolina requires an annual records review and a negative report filed through the Treasurer's site; Arizona and Montana do not require one at all. Checking that single question per state prevents a compliance gap that generates no money and still draws penalties.
Cryptocurrency is now inside the system
Digital assets have moved from an open question to a reporting obligation. California's SB 822, effective January 1, 2026, requires holders of virtual currency to attempt owner contact after three years of inactivity, according to the signing announcement from Senator Josh Becker's office. It is part of a broader 2026 wave of state digital-asset escheat rules.
The significant shift in those newer rules is the form of the remittance. States increasingly require crypto to be reported in native form rather than liquidated into dollars first, which means the owner receives the asset back rather than its value on some past date. For anyone with a dormant exchange account, the inactivity clock is now running the same way it does on a bank balance.
Two things to do before October 31
If you are an owner, treat this month as a deadline of your own. Any letter from a former bank, employer, insurer or brokerage asking you to confirm you are still there is a notice with a real expiry, and responding to it is faster than any state claim form.
If you file on the holder side, the early-review option is worth knowing about. Arizona is running a preliminary review for the cycle ending November 1, 2026, asking holders to submit a draft NAUPA II file — the standard national reporting format — about 120 days ahead for validation, with payment still due only with the final filing. A file rejected on November 1 for a formatting error is a late file.
Frequently Asked Questions
I got a due diligence letter about an account I closed years ago. Do I still respond?
Yes. Respond in writing and keep a copy. Closed accounts can retain residual balances, refunds or interest credits, and confirming your status now stops the escheatment and avoids a later state claim.
Does unclaimed property expire if I never claim it?
In most states the property remains claimable indefinitely once the treasury holds it. The practical cost of waiting is the paperwork and the proof-of-identity burden, not forfeiture.
My property was reported in California last November but the state database shows nothing. Why?
California's Notice Report and the Remit Report are separate filings. The property does not transfer until the following June 1–15 window, so it will not be searchable as state-held funds until then.
Do small amounts get reported at all?
They get reported, but they may not get a letter. Wisconsin's due diligence mailing requirement applies to property worth $50 or more, so smaller balances can reach the state without any notice to you.
