How to Pay Your CarMax Bill Online and by Mail

Where to pay your CarMax bill

CarMax accepts payments through their website, by phone, by mail, and in person at CarMax locations. The method you choose depends on how quickly you need the payment to post and whether you prefer online or offline options.

The fastest way to pay is through the CarMax website or mobile app, where payments typically post within one business day. Phone payments also process quickly but require speaking with a representative. Mail and in-person payments take longer — mail usually takes 7 to 10 business days to reach CarMax and post to your account, depending on postal delivery times in your area.

Key Takeaways

• CarMax payments made online or by phone post within one business day, while mailed payments take 7 to 10 business days.
• You can pay online through the CarMax website or app without creating an account if you have your account number and payment amount ready.
• Phone payments require calling CarMax customer service, and you will need your account number and a payment method (debit card, credit card, or bank account).
• Mailed payments should be sent to the address printed on your bill, and you should mail them at least 10 days before your due date to avoid late fees.
• In-person payments at CarMax locations are available during business hours, though not all locations may accept payments.

Paying online through the CarMax website or app

Visit carmax.com and look for a "Pay Bill" or "Make a Payment" link, usually located in the customer account section. You can also use the CarMax mobile app if you have it installed on your phone. You will need your account number, which appears on your bill or in your account login.

Enter your account number, the amount you want to pay, and your payment method. CarMax accepts debit cards, credit cards, and bank account transfers. Review the payment details before confirming, and you will receive a confirmation number when ready. The payment posts to your account within one business day.

If you do not have an online account set up, you can still make a one-time payment without logging in — you will just need your account number and payment method ready.

Paying by phone

Call CarMax customer service at the phone number on your bill or statement. A representative will ask for your account number and the amount you want to pay. Have your debit card, credit card, or bank account information ready.

Phone payments process the same day you call and post within one business day. The representative will give you a confirmation number before the call ends. Keep this number for your records in case you need to reference the payment later.

Paying by mail

Write a check or money order payable to CarMax. Include your account number on the check or money order — this helps CarMax match the payment to your account quickly. Place the check in an envelope with the payment coupon from your bill if you have one, or write your account number clearly on a separate piece of paper.

Mail the payment to the address printed on your bill. Do not send cash through the mail. Allow 7 to 10 business days for the payment to arrive and post to your account, so mail your payment at least 10 days before your due date to avoid a late fee.

If you are unsure of the mailing address, call CarMax customer service or check your online account — the correct address will be listed there.

Paying in person at a CarMax location

Some CarMax locations accept in-person payments during business hours. Call ahead to confirm that the location near you accepts payments, since not all locations may offer this service. Bring your account number and a payment method — cash, check, debit card, or credit card.

In-person payments post to your account within one business day. Ask for a receipt before you leave, and keep it with your records.

What to do if you miss a payment important date

If your payment does not post by the due date, contact CarMax customer service when ready. Explain when and how you made the payment — this information helps them locate it in their system. If you paid by mail and the payment has not arrived yet, provide the date you mailed it and the address you sent it to.

Late fees vary depending on your contract terms, so check your bill or account for the specific amount. If you are having trouble making a full payment, call CarMax to discuss your options — some situations may allow for a payment plan or extension.
