You reconcile your bank account and spot something odd: a vendor check you wrote seven months ago just cleared yesterday. Or the reverse — a contractor calls to say the check you mailed last spring never arrived, and asks you to send another. Either way, the same question lands on your desk: how long is a check actually good for, and who decides what happens when it goes stale?
The answer matters more than most business owners expect. An old check that clears without warning can overdraw your account. An old check you forget about can turn into a compliance obligation to the state. Here is how the rules work and the playbook for handling every aging check on your books.
The Six-Month Rule: Your Bank May Pay — or Refuse — a Stale Check
The controlling rule is Section 4-404 of the Uniform Commercial Code (UCC), the law every state has adopted in some form for bank deposits and collections. It says, in substance:
A bank is under no obligation to a customer having a checking account to pay a check, other than a certified check, presented more than six months after its date — but it may charge the customer's account for a payment made thereafter in good faith.
Read that carefully, because both halves bite:
- Your bank is allowed to bounce it. After six months from the date on the check, the bank owes you no duty to honor it. If a nine-month-old check arrives, the bank can return it unpaid, and you cannot complain that it should have paid.
- Your bank is also allowed to pay it. If the bank pays a stale check in good faith, it can charge your account, and you owe the money. "Stale" does not mean "void." The underlying obligation the check represented is not extinguished just because six months passed.
In practice, most checks clear through automated processing that reads the magnetic-ink (MICR) line — which does not include the check's written date — so stale checks routinely sail through. That is exactly why a surprise debit months later is normal, not a bank error. Plan your cash position as though any outstanding check could clear on any given day, no matter its age.
One exception is built into the rule: certified checks are carved out. When a bank certifies a check, it accepts primary liability on the spot, so the six-month discretion does not apply the same way. Cashier's checks and money orders live under related but distinct rules (more on those below).
"Void After 90 Days" Does Not Bind Your Bank
Many business checks carry a printed legend: "Void after 90 days," "Not valid after 180 days," or similar. Owners often assume this gives them an automatic stop-payment after the stated period. It does not.
Courts have treated that legend as a request from you to the payee — please deposit this promptly — not as an instruction to the bank. An Illinois appellate court held that a "void after 90 days" notation is not a stop-payment order and not a reasonable means of directing a bank to stop payment. After the stated period passes, the check is at most "stale" in the colloquial sense; the bank retains the right to pay it in good faith and charge your account.
Your own deposit agreement almost certainly says the same thing. Standard account disclosures provide that the bank may, without inquiry or liability, pay a check bearing special written instructions (void-after legends, amount caps, two-signature requirements), stale-dated checks, and post-dated checks. Banks disclaim these legends because high-speed automated processing cannot realistically police handwriting and fine print on millions of items.
The practical takeaway: print the legend anyway, but never rely on it. "Void after 90 days" genuinely nudges most payees to deposit faster, which shrinks your outstanding-check population. Just understand it is a behavioral nudge, not a legal control. If you need a control, you need a stop-payment order.
Special Cases: Cashier's Checks, Treasury Checks, and Money Orders
Not every payment instrument follows the six-month rule.
Cashier's checks and certified checks. Because the bank itself is the obligor, these do not go stale under Section 4-404. If one is lost, the UCC provides a specific remedy: the person entitled to enforce it can file a written declaration of loss with the bank, and the claim becomes enforceable 90 days after the check's date — a window that lets the original surface before a replacement is issued.
U.S. Treasury checks. Federal law is stricter and simpler: Treasury checks must be negotiated within 12 months of issue. The Treasury automatically cancels uncashed checks after one year and returns the funds to the issuing agency. If you receive a federal tax refund or benefit check, do not sit on it. A replacement can generally be requested, but claims are barred entirely if not filed within six years of issuance.
Money orders and traveler's checks. These are governed more by state unclaimed-property dormancy schedules than by presentment rules, and their dormancy periods run long — commonly several years. Do not assume an old money order is dead; the issuer typically still owes the funds.
Your Outstanding-Check Playbook: Review, Contact, Stop-Pay, Reissue
A disciplined monthly routine prevents nearly all stale-check pain. Here is the sequence that works:
1. Age your outstanding checks every month
Your bank reconciliation should produce an outstanding-check list with the issue date of each item. Sort it into buckets — under 30 days, 30–90 days, 90–180 days, over 180 days — and treat the older buckets as action items, not trivia. Checks sitting past 90 days deserve a phone call; checks past 180 days deserve a decision.
2. Contact the payee before you do anything else
Most stale checks have boring explanations: the check is in a drawer, the bookkeeper changed, the vendor applied it to the wrong account. A short call or email resolves the majority. Document the outreach with dates — that record becomes your due-diligence evidence later if the item drifts toward escheatment.
3. Stop-pay and reissue when the original is lost
If the payee confirms the check never arrived or was destroyed, place a formal stop-payment order and issue a replacement. Know the mechanics under UCC Section 4-403:
- A stop order is effective for six months and can be renewed in writing for additional six-month periods.
- An oral order lapses after 14 calendar days unless you confirm it in writing — so follow up the phone call with the bank's written form or online confirmation the same day.
- Banks charge a fee per order, commonly in the $15–$35 range, and renewals cost again. Factor that into whether a small-dollar check is worth reissuing versus crediting the payee's account another way.
- The burden of proving loss from a payment made over a valid stop order falls on you, the customer — another reason to confirm orders in writing and keep the confirmation.
Never reissue without stopping the original. Double payment on the same obligation is a common and entirely avoidable loss, and "I assumed the old one was too stale to clear" is exactly the misunderstanding Section 4-404 punishes.
4. Book the reissue correctly
When you stop-pay and reissue, void the original in your books (credit cash, debit the outstanding-checks or accounts-payable clearing rather than leaving the stale item floating), then record the replacement as a new disbursement. For a lost check you agree to reissue after a long delay, consider sending the replacement by a trackable method or switching the payee to ACH — every paper reissue restarts the same aging clock.
When Outstanding Checks Become the State's Money
Here is the part that surprises owners most: you cannot simply write an old outstanding check back into income and move on. Uncashed checks are unclaimed property, and every state has an escheatment regime that eventually transfers the funds to the state for safekeeping on the payee's behalf.
Key points for a small business holding outstanding payroll or vendor checks:
- Dormancy periods depend on the property type and the payee's address. Payroll and wage checks commonly go dormant after one year in many states, while most other property — including vendor checks — typically runs three years, with some states longer. Because the applicable period follows the owner's last known address, a multi-state payee list means a multi-period tracking obligation.
- Due diligence comes first. Before reporting, holders must attempt to locate the owner — typically a first-class letter to the last known address within a set window before the property is presumed abandoned. Keep copies; states audit this step.
- Then you report and remit. Outstanding amounts are reported on the state's unclaimed-property return and the funds are turned over to the state. The liability never converts to your revenue.
- Penalties are real. Late reporting draws interest and penalties, and states increasingly audit small and mid-size businesses specifically for unclaimed-property compliance, with lookback periods stretching a decade or more in some jurisdictions.
Build this into your year-end close: an outstanding check approaching its dormancy birthday should be flagged the same way an expiring contract is. The journal entry when escheatment hits is a reclass — from outstanding checks payable to unclaimed-property liability — not a gain.
Keep Your Outstanding Checks Under Control From Day One
Stale checks are a bookkeeping problem before they are a legal problem. A few habits keep the population small and the aging list honest:
- Reconcile bank accounts monthly without exception. The outstanding-check list is a byproduct of a real reconciliation, not a report you glance at quarterly.
- Track checks in a dedicated clearing account or detailed subledger, so voided, stopped, and reissued items leave an audit trail instead of vanishing into a miscellaneous expense line.
- Prefer electronic payments for recurring payees. ACH and bill-pay transfers cannot go stale, cannot be lost in the mail, and reconcile themselves.
- Calendar dormancy. When a check crosses 90 days, contact the payee. When it crosses a year, start the due-diligence file. When the state's clock runs out, report and remit.
A check is a promise that lingers. The bank may honor it months late, the legend you printed will not stop it, and the state will eventually claim it if nobody cashes it. Owners who age their outstanding checks monthly, stop-pay before reissuing, and escheat what they cannot deliver keep all three of those risks where they belong — on a checklist, not in a crisis.
