An A/R refund check is a payment a business sends you to return money you overpaid or that the business otherwise owes you after a billing adjustment. Accounts receivable normally tracks what customers owe the company; when your balance goes negative, the company owes you, and the check settles that liability. Most of these are routine, but an unexpected one is worth a closer look before you sign the back.
Why the Check Showed Up
The most common trigger is a plain overpayment. You pay an invoice, a credit gets applied to the same account later, and your balance drops below zero. That surplus sits as a credit on the company’s books until the accounting team catches it and cuts a check. Duplicate payments and miscalculated fees produce the same result.
Canceling a subscription or service mid-cycle is another frequent cause. If you prepaid for a full month or quarter and canceled partway through, the unused portion becomes a refundable credit. Returning a high-value item after your payment cleared works the same way.
Contract closures and account terminations often trigger a final audit. Security deposits, over-estimated final bills, and prorated charges get trued up. Medical providers are especially prone to delayed refunds because insurance claim settlements can take months after you’ve already paid a co-pay or deductible. Once the insurer pays its share, the provider finds a credit on your account.
For credit accounts specifically, federal rules set a timeline. A creditor holding a credit balance over one dollar must refund any remaining balance within seven business days of receiving your written request. If the balance sits untouched for more than six months, the creditor must make a good faith effort to return it by check, cash, or account deposit.1eCFR. 12 CFR 1026.11 – Treatment of Credit Balances; Account Termination Outside the credit context, no single federal rule sets a universal deadline, but most companies process refunds within a few weeks of spotting the overage.
How To Tell the Check Is Real
An unexpected refund should raise a mild flag, not panic. The difference between a legitimate refund and a scam is almost always in what happens next: a real refund asks nothing of you, while a scam asks you to send money back.
The FTC describes the classic overpayment scam this way: someone sends you a check for more than they owe, then asks you to return the difference by gift card, wire transfer, or cryptocurrency. The check clears initially because banks are required to make funds available within a few days, but the check itself can take weeks to bounce. By the time it does, you’ve already sent real money to the scammer.2Federal Trade Commission. How To Spot, Avoid, and Report Fake Check Scams
A legitimate refund lines up with a few markers:
- The check or attached remittance advice references an account number that matches your records with the company.
- Nobody is asking you to wire anything back or buy gift cards. You deposit it and you’re done.
- The issuing bank name and routing number belong to a real financial institution.
- The check has physical security features: a perforated edge, watermarks, and a nine-digit routing number. A flimsy check without these is suspect.
If anything feels off, call the company using a phone number from your original statements, not one printed on the check or the letter that came with it. If the check turns out to be fraudulent, report it to the FTC and your state attorney general.2Federal Trade Commission. How To Spot, Avoid, and Report Fake Check Scams
One note about the name on the check: some companies outsource disbursements to third-party payment processors, so the issuer may be a financial services firm you don’t recognize. The attached documentation should link the payment to the company you actually did business with.
Depositing the Check
Endorse the back and deposit it. For mobile deposit, add a restrictive endorsement like “for mobile deposit only” under your signature; your bank may have its own rules for mobile compared with in-branch deposits.3Consumer Financial Protection Bureau. How Long Can a Bank or Credit Union Hold Funds I Deposited? Hold onto the physical check for at least 30 days after deposit so you can confirm the funds clear.
Federal rules cap how long your bank can hold the funds. For a check drawn on a bank in the same processing region, funds must be available by the second business day after deposit. For a check from a bank in a different region, the limit is the fifth business day.4eCFR. 12 CFR 229.12 – Availability Schedule Banks can extend those holds in certain situations, sometimes up to the ninth business day, and if they do, they have to notify you.5eCFR. 12 CFR 229.13 – Exceptions Many banks release funds faster than required, but with an unfamiliar issuer, wait for the release before spending against the deposit.
Don’t Let It Sit: Stale Dates and Reissues
Under the Uniform Commercial Code, a bank has no obligation to honor a check presented more than six months after the date on its face.6Cornell Law School. Uniform Commercial Code 4-404 – Bank Not Obliged To Pay Check More Than Six Months Old Many business checks print “void after 90 days” or “void after 180 days” on the face, which can shorten the window further. A bank isn’t required to refuse a stale check, but it isn’t required to pay it either, and most will decline.
If your check has gone stale, call the issuing company’s accounting department and ask for a reissue. They’ll typically place a stop payment on the original and cut a new one. That’s straightforward as long as the funds haven’t already been turned over to the state as unclaimed property. Once escheatment happens, the reissue process gets more complicated.
Do You Owe Tax on It?
A refund of money you overpaid is generally not taxable income. You’re getting your own money back. If you overpaid an electric bill by $47 and receive a check for $47, that amount doesn’t go on your tax return.
The exception is the tax benefit rule. If you deducted the original payment on a prior year’s return and that deduction reduced your tax, the refund counts as a recovery and must be included in income for the year you receive it.7Internal Revenue Service. Publication 525 – Taxable and Nontaxable Income This comes up most often with state and local tax refunds: if you itemized and deducted state income taxes one year, then received a refund the next, that refund is taxable to the extent it gave you a tax benefit. The same logic applies to refunds of medical expenses or business expenses you previously deducted.
For a routine refund from a utility, a doctor’s office, or a retailer, there’s usually nothing to report. Businesses are not required to issue a 1099-MISC or 1099-NEC for ordinary customer refunds.8Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC If you’re unsure whether the tax benefit rule applies, IRS Publication 525 walks through the calculation.
What Happens If You Never Cash It
Ignoring a refund check doesn’t mean the money vanishes, but recovery gets harder. Every state has unclaimed property laws that require businesses to turn over dormant funds after a set period. For uncashed checks, the dormancy period across most states runs three to five years, though some states use shorter or longer windows.
Once that period passes, the issuing company reports your uncashed check to the state, and the funds go into the state’s unclaimed property program. You can search for property in your name at MissingMoney.com, the national database endorsed by the National Association of Unclaimed Property Administrators and the National Association of State Treasurers.9MissingMoney.com. Search for Unclaimed Property Claiming involves searching by name, filing a claim, and verifying your identity.
The cleaner path is to deposit refund checks promptly. If you’ve moved and a check may have gone to an old address, contact the issuing company before the dormancy clock runs out. After escheatment, the company can’t help you, and you’ll be working through the state’s unclaimed property office instead.
