The IRS mails refund checks in a white envelope with a specific layout and security features
A federal tax refund check arrives in a standard white business envelope, roughly 4.5 inches tall by 9.5 inches wide. The envelope has no window — your name and address are printed directly on the front in the standard mailing position. The return address in the upper left corner reads "Internal Revenue Service" with a city and state, usually Kansas City, MO or another IRS processing center. The envelope itself is plain, with no logos or graphics other than the text.
The check inside is printed on security paper with a watermark and microprinting that make it difficult to counterfeit. The check number appears in the upper right corner. Your name, address, and the refund amount are all printed on the check itself. The check is drawn on the U.S. Treasury and signed by an IRS official. The back of the check has standard banking information and instructions for depositing or cashing it.
Some refund envelopes include a letter explaining the refund amount and any adjustments the IRS made to your return. This letter is usually a single page printed on white paper with the IRS letterhead. If you received a notice of adjustment or correction, that document will be in the same envelope.

How to verify the check is legitimate before you deposit it
Before you cash or deposit the check, confirm that the amount matches what you expected. You can check your refund status on the IRS website using the "Where's My Refund?" tool with your Social Security number, filing status, and the exact refund amount. If the check amount does not match what the tool shows, do not deposit it — contact the IRS at 1-800-829-1040 instead.
Verify that your name and address are spelled correctly on the envelope and check. The IRS will mail to the address you provided on your tax return, so if you have moved since filing, the check may arrive at your old address. If someone else receives your check, they should forward it to you unopened or contact the IRS to report the misdirected mail.
Check the date on the check. IRS refund checks are valid for one year from the date printed on them. If more than a year has passed, the check may no longer be cashable at most banks, though you can contact the IRS to request a replacement.
What to do if the envelope looks suspicious or damaged
If the envelope is torn, wet, or appears to have been opened before it reached you, do not assume the check is counterfeit. Mail carriers sometimes damage envelopes in transit. Open it carefully and inspect the check for damage. If the check itself is readable and the amount is correct, you can usually deposit it normally.
If the envelope has no return address or the return address does not say "Internal Revenue Service," it is not from the IRS. Scammers sometimes send fake refund checks in envelopes designed to look official. Real IRS refund envelopes always show the IRS name and a processing center address on the return line.
If you receive a check you did not expect and cannot find any record of filing a return that year, contact the IRS before depositing it. The check may be a duplicate, a payment for a different tax year, or an error. The IRS can tell you what the check is for and whether it is legitimate.
Timing between mailing and arrival at your address
The IRS typically mails refund checks within 21 days of approving your return, though this can vary depending on processing delays or errors on your return. Once mailed, a check usually arrives within 7 to 10 business days, though mail delivery times vary by location and season. During tax season (January through April), mail can take longer.
If you have not received your check within 10 business days of the mailing date shown in "Where's My Refund?", wait a few more days before contacting the IRS. Postal delays are common, especially in rural areas or during winter months. If more than two weeks have passed since the mailing date, contact the IRS to report the missing check.
What the explanatory letter inside the envelope tells you
If the IRS made changes to your return before issuing the refund, they will include a letter explaining what changed and why. This letter shows the original amount you claimed, the adjustment the IRS made, and the final refund amount. Common reasons for adjustments include math errors, missing documentation, or discrepancies between your return and information the IRS received from employers or financial institutions.
Keep this letter with your tax records. If you disagree with the adjustment, the letter will include instructions for filing an appeal or requesting a reconsideration. You have a limited time to respond, usually 30 days from the date of the letter, so do not discard it.
If the letter mentions a notice of deficiency or a proposed assessment, this is more serious than a simple adjustment. Read it carefully and follow the instructions for responding. You may want to contact a tax professional or the IRS Taxpayer Advocate Service if you do not understand the letter.
Refund checks that arrive after you have moved
If you filed your return before moving and did not update your address with the IRS, your refund check will go to the address on your return. The postal service may forward it to your new address if you filed a change of address form, but this is not may provide. Some forwarding orders expire after a year.
If your check was mailed to your old address, contact the person living there and ask them to forward it to you unopened. If you cannot reach them, contact the IRS and provide your new address. The IRS can issue a replacement check, though this can take several weeks.
To avoid this problem in the future, update your address with the IRS before filing your return. You can do this on the IRS website or by mail. If you have already filed and moved, call the IRS at 1-800-829-1040 to update your address before your refund is mailed.
Frequently Asked Questions
Can I deposit a tax refund check at any bank?
Yes, you can deposit a federal tax refund check at any bank or credit union where you have an account. You can also cash it at most banks even if you do not have an account there, though some may charge a fee. Grocery stores and check-cashing services will also cash IRS checks, though fees may be higher.
What if I lost the check before depositing it?
Contact the IRS at 1-800-829-1040 and report the lost check. Provide your Social Security number, filing status, and the refund amount. The IRS will issue a replacement check, which usually takes four to six weeks. Do not deposit the original check if you later find it, as it will be flagged as a duplicate.
Can someone else deposit my refund check if I sign the back?
Yes, you can endorse the check to another person by signing the back and writing "Pay to the order of [their name]." They can then deposit it in their account. However, some banks require both you and the other person to be present to deposit a third-party check, so call your bank first.
How do I know if a check claiming to be a refund is actually from the IRS?
Check the return address on the envelope — it must say "Internal Revenue Service" with a city and state. Verify the amount using the IRS "Where's My Refund?" tool on irs.gov. If the amount does not match or you have no record of filing a return, contact the IRS before depositing the check. Scammers sometimes send fake checks, so verify before cashing.
What if the refund amount on the check is less than I expected?
The IRS may have adjusted your return or applied part of your refund to other taxes you owe. Check the explanatory letter that came with the check — it will explain any reductions. If there is no letter or you do not understand the adjustment, contact the IRS at 1-800-829-1040 to ask why the amount is lower.
