Dealer won't take my cashier's check? How to pay for a car
Direct answer: Yes, a dealer can refuse a cashier's check, because fakes look real and can take weeks to surface. Fixes: let the dealer call your bank at the number on its website to verify the check, send a wire after confirming the account by phone, or have your bank or credit union pay the dealer directly.
By the numbers: On a car sale over $10,000, a dealer must file IRS Form 8300 within 15 days if it receives more than $10,000 in cash, which includes cashier's checks and money orders of $10,000 or less. Source: IRS Form 8300 Reference Guide
Quick Q&ACan a car dealer refuse a cashier's check?
Yes. A dealer chooses which payment methods it accepts. Many verify a cashier's check with the issuing bank first or ask for a wire instead.
Does a cashier's check over $10,000 count as cash for Form 8300?
No. Per the IRS, a single cashier's check over $10,000 is not cash for Form 8300; cashier's checks of $10,000 or less are, when used in a sale over $10,000.
Is wiring money to a dealer safe?
Confirm the dealer's account details by phone at a number you already know. Faked wiring instructions sent by email are a common scam, and wires are hard to reverse.
As of Oct. 16, 2026
Short answer: A dealer is allowed to refuse a cashier's check. Fakes look real even to bank employees and can take weeks to surface (FTC). The easy fixes: let the dealer verify the check with your bank at the number on the bank's website, send a wire after confirming the account by phone, or have your bank or credit union pay the dealer. On a car over $10,000, the dealer must file Form 8300 if it gets more than $10,000 in currency plus cashier's checks or money orders of $10,000 or less. One cashier's check over $10,000, a wire, a personal check or a card doesn't count. Check my payment.
Type how you plan to pay. Nothing you type leaves your phone.
Best move: agree on the payment method before you go
Call the dealer before you go and agree on how you'll pay. Ask which methods it takes, whether it verifies cashier's checks with the issuing bank, and its card limit and fee. If you're wiring, get the account details in person or confirm them by phone at a number you already know.
The math:
$32,000 car: $20,000 credit union loan + $6,000 cashier's check + $6,000 currency → the IRS counts $12,000 as cash → the dealer files Form 8300.
Same car: $20,000 loan + one $12,000 cashier's check → $0 counts as cash (the check is over $10,000) → no Form 8300.
$9,500 car paid with a $9,500 cashier's check → not a designated sale (price not over $10,000) → $0 counts as cash.

Your roadmap
Pick your method with the table below.
Call the dealer and confirm it takes that method, and for how much.
Cashier's check? Get it from your bank, and bring the bank's phone number from its website so the dealer can verify it.
Wire? Confirm the dealer's account by phone at a known number, send it, then call to confirm it arrived.
Keep the paper: buyer's order, receipt showing each payment, and any Form 8300 statement the dealer sends you by Jan. 31.
Every way to pay, side by side
“Counts as cash” is for a retail car sale over $10,000, per the IRS. Bank availability times are the federal maximums under Regulation CC; many banks are faster.

Sending a wire without getting scammed
Scammers send spoofed emails with fake wiring instructions at the last minute. The CFPB says never follow wiring instructions from an email and don't use phone numbers or links in one.
Confirm the account name and number in person, or by calling a number you already had (the dealership's main line from its website or your buyer's order).
If the instructions “changed,” treat it as a scam until you've confirmed by phone.
Sent it to the wrong place? Call your bank right away and ask for a wire recall, then file at ic3.gov. Regulation E's error rules don't cover Fedwire-type wires (12 CFR 1005.3(c)(3)), so speed matters.
Who files: the business, not you. A car dealer files when it receives more than $10,000 in cash in one sale or related sales. Payments within 24 hours are related, and so are connected payments further apart.
What counts as cash: U.S. and foreign currency. On the retail sale of a car priced over $10,000 (a “consumer durable”), also cashier's checks, bank drafts, traveler's checks and money orders with a face value of $10,000 or less.
What doesn't: personal checks; a cashier's check, bank draft, traveler's check or money order over $10,000; any transmittal of funds from a financial institution, such as a wire. The IRS example: $4,000 currency + $15,000 wire = no filing.
Deadlines: the dealer files within 15 days and must give you a written statement by Jan. 31 of the following year. A copy of the form itself isn't required.
Structuring: breaking a large cash payment into smaller ones to dodge the report. The IRS says the penalties can apply to any person, including the payer.
Private sales: if you sell your own car for cash, you don't file. Form 8300 is for people in the business.
Exceptions we don't model: checks received more than 60 days before the sale under a down-payment plan, and payments on installment contracts that meet IRS conditions.
Why a dealer may hold the car until a check clears
The dealer's bank must make a cashier's check deposited in person available the next business day (second business day if not deposited in person) (12 CFR 229.10(c)).
But that only applies to the first $6,725 of check deposits a banking day. The bank can hold the rest longer under the large-deposit exception and must give notice (12 CFR 229.13(b)).
And “available” isn't “good.” The FTC says fakes can take weeks to be discovered, and the OCC says the person who deposited a fake may owe the bank the full amount.
Not legal or tax advice. Federal rules only; we didn't find a Tennessee law that requires a dealer to take any particular payment, but check your own state.
Dealer policies (card limits, card fees, check holds) vary by store. Ask the dealer.
Bank availability times are federal maximums. Your bank's funds-availability policy may be faster.

Not legal or tax advice. We republish federal rules with dates and do the arithmetic on what you type. Your dealer's policy and your bank's rules decide what happens on deal day.
Yes. No federal law requires a business to accept a particular form of payment. A cashier's check isn't legal tender (31 U.S.C. 5103 covers U.S. coins and currency), and the Federal Reserve says private businesses set their own payment policies unless a state law says otherwise. Dealers worry about fakes: the FTC says fake checks can look real even to bank employees and take weeks to discover.
Does a cashier's check over $10,000 trigger Form 8300?
No. The IRS says a cashier's check, bank draft, traveler's check or money order with a face value of more than $10,000 is not cash for Form 8300. On a car priced over $10,000, instruments of $10,000 or less do count, along with any currency. A $12,000 cashier's check alone is not reported; a $6,000 check plus $6,000 currency is.
Does a wire transfer to a car dealer get reported on Form 8300?
No. The IRS says any transmittal of funds from a financial institution, such as a wire, is not cash for Form 8300. Its example: $4,000 currency plus a $15,000 wire is not reported.
What happens if a dealer files Form 8300 on me?
The dealer files the report with the IRS and FinCEN within 15 days and must send you a written statement by January 31 of the next year. It's an information report, not a tax bill. Breaking payments up to avoid it (structuring) can bring penalties, including for the buyer.
How do I verify a cashier's check?
Call the bank that issued it using the phone number on the bank's official website, not the number printed on the check, and give the check number, issue date and amount (FDIC). Don't rely on money showing as available: the OCC says a fake can take weeks to discover and the depositor may owe the bank the full amount.
How do I wire money to a dealer safely?
Get the wiring instructions in person or confirm the account name and number by calling a number you already know. Never follow instructions in an email (CFPB). If a wire goes to the wrong place, call your bank immediately for a wire recall and report it at ic3.gov.
