Walk into the accounts payable folder of any company that has been operating for more than five years and you will almost certainly find a small graveyard: vendor checks that were issued, mailed, and never cashed; payroll checks for a barista who quit before payday; a stack of rebate credits no customer ever redeemed; gift card balances that have not been touched since the holiday season three years ago.
To the controller, those balances feel like found money — a quiet pickup that boosts other income on next quarter's P&L. To the state where the owner of that money last lived, they are something different. They are unclaimed property. And under every single state's escheat statute, that money is not yours to keep. It belongs to the state in trust for the rightful owner, and your company has a legal duty as the "holder" to identify it, run a final outreach to find the owner, and turn it over on a schedule the state sets — typically once a year, in a specific electronic format, with a specific cover affidavit, on a specific date.
Approximately one in seven Americans has unclaimed property sitting with a state administrator. Roughly $77 billion is being held nationwide right now. A meaningful slice of that came from small and mid-sized businesses that quietly wrote off stale checks to miscellaneous income instead of reporting them. Some of those businesses are about to get an audit letter. Here is how to stay out of that envelope.
What Counts as Unclaimed Property (and What Does Not)
Unclaimed property is a state-law concept, not a federal one. The IRS plays no role here. Each state — plus the District of Columbia, Puerto Rico, and Guam — runs its own program, usually out of the state treasurer's or comptroller's office, and each one has its own statute, dormancy table, due diligence rule, and filing deadline.
The unifying idea is simple. If your business is holding intangible property that legally belongs to someone else, and you have lost contact with that person for a defined period (the "dormancy period"), the property is presumed abandoned. Once it is presumed abandoned, you stop being a creditor and start being a holder, and the state takes custody of the money on the owner's behalf. The owner can claim it from the state forever — there is no statute of limitations on the rightful owner's right to recover it — but you, the business, lose the ability to use it.
The categories that catch small businesses off guard:
- Uncashed vendor checks. Your vendor moved, forgot to deposit a check, or the check got eaten by the office printer. Three to five years later it is still sitting on the bank reconciliation as outstanding.
- Uncashed payroll checks and final paychecks. Especially common in restaurants, retail, construction, and any business with high turnover. Most states give these a one-year dormancy clock — the shortest of any property type.
- Customer credits, refunds, and overpayments. A customer paid twice, you booked the credit, and they never asked for it back.
- Unredeemed gift cards and store credit. Whether these escheat depends on the state and whether the card has an expiration date or fees. Some states fully exempt them; some take the full face value; some take only a percentage.
- Rebates and promotional credits. Issued, never claimed.
- Security deposits. Especially landlord, utility, and equipment-rental deposits.
- Stock dividends, mineral royalties, and insurance proceeds. Less common for small businesses, but they exist.
- Unidentified deposits and stale cash receipts. Money came in, you booked it, and you never figured out whose it was.
A useful test: if a line item on your trial balance represents a liability you owe to a specific, identifiable third party, and you have not heard from that third party in a couple of years, it is a candidate.
Dormancy Periods: When the Clock Starts and Stops
The dormancy period is the length of time, measured from the date of last owner contact or last activity, after which the property becomes reportable. The Revised Uniform Unclaimed Property Act of 2016 (RUUPA) — the model statute the Uniform Law Commission has nudged states toward — sets a general dormancy period of three years. In practice, you have to look at each state separately because none of them adopted RUUPA in pure form.
Rough ranges by property type:
- Wages, payroll, commissions: one year in most states.
- Vendor checks and accounts payable credits: three to five years.
- Customer credit balances: three to five years.
- Gift cards and stored-value cards: highly variable. Pennsylvania, for instance, treats gift cards as abandoned two years after the listed expiration date, or five years after issuance if there is no expiration. Many states exempt them entirely if the card has no expiration and no service fee. Others escheat only the unused balance, sometimes at less than face value.
- Money orders and traveler's checks: seven years.
- Securities and dividends: three years after the position becomes "lost."
The clock starts on the "trigger event" — usually the issue date of a check, the date of last owner contact, or the last activity on the account. Mailing a statement that comes back as "return to sender" generally does not reset the clock. A signed delivery receipt, a returned phone call, or a logged email response usually does.
Which State Gets the Money: The Texas v. New Jersey Rule
If you have a Texas vendor, a New York payroll employee, and a California customer, which state do you report to? The Supreme Court answered this in Texas v. New Jersey (1965) with a two-step priority rule that every state and every holder still follows today:
- First priority: the state of the owner's last known address as shown on your books and records.
- Second priority: if you do not have a last known address (or the address is in a foreign country), the state of the holder's incorporation.
That second-priority rule is why Delaware — the legal home of more than a million U.S. corporations — has the most aggressive unclaimed property program in the country. If your books say "uncashed AP check, payee Acme Widgets, address unknown," and your company is incorporated in Delaware, that money is reportable to Delaware. The same logic applies to your state of incorporation, whatever it is.
This is also why the books and records you keep matter so much. A complete vendor master with current addresses keeps property out of the second-priority bucket. A sloppy master sends it to your incorporation state, which is almost always the worst place for a holder.
Due Diligence Letters: Your Last Chance to Avoid Reporting
Before you can turn the property over to the state, every state requires you to try one more time to find the owner. This is the due diligence letter — the last call before escheat.
The mechanics vary widely, but the structure is the same. A few weeks to a few months before the holder report is due, you mail a letter to the owner at the last known address on your books. The letter has to identify the property, state that it will be turned over to the state if the owner does not respond by a deadline, and tell the owner how to claim it from you directly. If the owner responds and confirms they still want the property, you remove that item from the report and pay them. If the letter comes back undeliverable, or the owner never responds, the property stays on the report.
Key parameters that differ state by state:
- Dollar threshold. Most states only require due diligence letters above a floor. Many states set that floor between $25 and $50. Texas sits at $250. Some states require the letter regardless of size.
- Mailing window. Most states require the letter to go out 60 to 120 days before the report is filed. RUUPA pushes the window to 60 to 180 days. California is an outlier — its first-cycle letter must go out six to twelve months before the report.
- Delivery method. First-class mail covers most states. A few — including Ohio and New York — require certified mail when the property exceeds $1,000. Some states accept email if you have a verified electronic address on file.
- Content. Several states publish a model letter or required elements. Boilerplate from a service provider is fine in most states; in a few, it is not.
A surprisingly large number of items get claimed at the due diligence stage. Owners get the letter, remember they meant to deposit the check, and cash it. Every item that closes out at this stage is one less item on the state report, one less liability transfer, and one less data point that could trigger an audit.
The Holder Report: Format, Filing, and Funds Transfer
After the due diligence window closes, you assemble the annual holder report. The report has three parts: a summary of the property by type and total value, a detail file listing every item with the owner's name, address, property type code, and amount, and a cash remittance for the total balance.
Almost every state accepts (and most now require) the NAUPA II electronic file format, a standardized layout the National Association of Unclaimed Property Administrators has maintained for more than two decades. If you file in multiple states — and once you reach any kind of scale, you will — using the NAUPA II format end-to-end is non-negotiable. It is the difference between filing fifteen reports in three hours and filing them in three weeks.
Filing deadlines split into two camps:
- November 1 is the most common deadline. Most states require general business holders to file by November 1 for property that became reportable during the prior fiscal year ending June 30.
- March 1 is Delaware's deadline for general holders (banks file November 10). Several other states use March 1 as well.
The funds transfer happens at the same time as the report. Most states accept ACH; many also accept wire and physical check.
Penalties, Audits, and the Delaware Problem
States have grown progressively less patient over the last decade. The carrots — voluntary disclosure agreements, amnesty programs, abbreviated lookback periods — are still on the table, but the sticks have gotten bigger:
- Interest typically runs at 10% to 18% per year on the unreported balance.
- Civil penalties range from $100 to $200 per day per item, capped in some states and uncapped in others.
- Fraud penalties can double the assessment if the state proves willful failure to report.
- Audit lookback periods can extend ten, fifteen, or in Delaware's case effectively back to 1981, the year the state's escheat program took its modern form. If you have never filed a report and Delaware decides to audit you, the dollar exposure on a thirty-plus-year lookback is the existential risk most CFOs do not see coming.
Delaware is the state most likely to drop the audit envelope on a corporation it has never heard from before, because so many companies are incorporated there. It contracts with third-party audit firms that work on a contingency basis — they keep a cut of what they collect — which means there is a real economic engine pushing the audit pipeline forward.
The most important defensive move available to a non-filer is the Voluntary Disclosure Agreement, or VDA. Delaware (and most other states) will waive penalties and interest, and shorten the lookback period to roughly ten years, if you proactively raise your hand before they show up. Once an audit notice arrives, the door to the VDA program closes. If you have never filed and you might owe something, get in line for the VDA before the line gets to you.
A Practical Workflow for a Small Business
You do not need a six-figure compliance team to handle this. A small business can run the whole cycle with a checklist and a couple of weekends:
- Inventory the candidate liabilities. Pull aging reports for outstanding checks (AP and payroll), customer credit balances, gift card liability, and any other contra-revenue or refund accruals. Anything older than the shortest possible dormancy period (one year) gets flagged.
- Identify the owner state for each item using the last known address on your records. Items with no address default to your state of incorporation.
- Build the dormancy table for your states. Pull each state's current statute and confirm the dormancy period for each property type. A spreadsheet works; software is faster if you have hundreds of items.
- Send due diligence letters to every owner above the state's threshold within the state's mailing window. Track responses. Pay anyone who claims their property and remove them from the report.
- Generate the NAUPA II file, sign the holder affidavit, fund the report (ACH or check), and file before the state's deadline.
- Document everything. Keep the dormancy analysis, the due diligence mailing log, the responses, the final report, and proof of transmission for the audit retention period (usually ten years).
- Repeat annually. The first cycle is the hard one. After that, it is a steady-state process.
If your books reveal a problem that goes back further than the past year — say, three years of stale checks that were quietly written off to miscellaneous income — talk to a state unclaimed property specialist about a VDA before you file. Filing a clean report this year does not erase prior-year exposure; only a VDA does.
The Bookkeeping Hook
The two operational habits that prevent the unclaimed property mess in the first place both come out of your accounting system:
- Don't write stale checks off to miscellaneous income. Carry them on the balance sheet as a liability until they escheat. Booking them to income makes them invisible to the audit team that later needs to identify them, and it overstates net income in the year you wrote them off.
- Keep your vendor, customer, and employee master files current. Every undeliverable address is a future escheat item. Address quality is the single biggest lever you have over your second-priority exposure.
Both habits live in your general ledger and chart of accounts. Both are trivially easy if your books are clean and almost impossible to fix retroactively if they are not.
Keep Your Records Defensible from Day One
Unclaimed property compliance is a paperwork problem at its core. The companies that get audited and settle quickly are the ones that can produce, on demand, a complete vendor master, an aged trial balance, a check register tied back to the bank, and a documented history of due diligence outreach. The companies that get audited and get hurt are the ones whose books are a black box.
