Start with the IRS, but know what they can and cannot tell you

The Internal Revenue Service (IRS) is your first call for a federal tax refund delay. They maintain the refund status for every return filed, and they can tell you whether your return is still being processed, held for review, or sent out. Call the IRS at 1-800-829-1040 (individual returns) or 1-800-829-4933 (business returns). Have your Social Security number, filing status, and the exact refund amount from your return ready.

The IRS can confirm that your return arrived, show you the current processing stage, and tell you the expected delivery date if one has been set. They cannot speed up processing or override a hold, but they can tell you why a hold exists — for example, whether the IRS is verifying income, requesting documents, or flagging the return for identity verification. That information tells you what to do next.

Wait times at the IRS phone line are long, especially during tax season (January through May). The IRS also offers a refund status tool on their website at irs.gov/refunds that works 24 hours a day. You enter your Social Security number, filing status, and refund amount, and the system shows you the same information a phone representative would give you. This tool updates once per day, usually overnight.

Key Takeaways

  • Call the IRS at 1-800-829-1040 to confirm your return was received and learn why processing is delayed.
  • The IRS refund status tool at irs.gov/refunds works 24 hours and shows the same information as a phone call without the wait.
  • If the IRS is requesting documents or verification, they will tell you what they need and where to send it; ignoring this request extends the delay.
  • State tax refunds are handled by your state revenue department, not the IRS, and require a separate call to that agency.
  • If your refund was sent but never arrived, contact the IRS about reissuing it; if it was deposited to the wrong account, your bank can help trace it.

What the IRS will tell you about your specific delay

When you call or check online, the IRS categorizes your refund into one of four statuses: accepted (received but not yet processed), processing (under review), approved (ready to send), or sent (on its way to you). Each status comes with a timeline. An "accepted" return typically moves to "processing" within 24 hours. A return in "processing" usually takes 21 days from the filing date, though some returns take longer if they require additional review.

If your return shows "processing" after 21 days, the IRS has flagged it for one of several reasons: the return contains math errors, income reported on the return does not match what employers or financial institutions reported to the IRS, the return claims a refundable credit (like the Earned Income Tax Credit) that requires verification, or the IRS suspects identity theft. The IRS will not tell you which reason applies over the phone — they will only say "your return is under review." You can request a transcript of your account at irs.gov/transcripts to see notes the IRS has added, though these notes are often vague.

If the IRS is requesting documents, they will send you a letter (called a notice) to your mailing address. This letter explains what documents you need to send and where to send them. If you have not received a letter but the IRS says your return is under review, ask whether a notice was mailed. If one was mailed but you did not receive it, the IRS can resend it or tell you the deadline for responding.

Contact your state revenue department for state refund delays

If you filed a state return and your state refund is delayed, the IRS cannot help you — each state handles its own refunds. Find your state's tax agency by searching "[your state] department of revenue" or "[your state] tax commission." Most states have a phone number for refund status and a website tool similar to the IRS's.

State processing times vary widely. Some states issue refunds within two weeks of receiving a return; others take six to eight weeks. If you filed electronically, your state refund usually arrives faster than a paper return. Some states offset refunds against unpaid child support, student loans, or other debts owed to the state, which adds time to processing. The state revenue department can tell you whether an offset is holding your refund.

A few states use third-party vendors to process returns and issue refunds. If your state uses a vendor, the state revenue department will direct you to call that vendor instead. For example, some states contract with Refund Advance or other companies to handle refund delivery. The state can give you the vendor's phone number.

If the IRS says your refund was sent but you never received it

The IRS marks a refund as "sent" once it has been delivered to your bank (for direct deposit) or mailed to you (for a check). If the IRS says your refund was sent but you have not received it, the next step depends on the delivery method.

For direct deposit, call your bank and ask whether the deposit arrived. Provide the bank with the refund amount and the date the IRS says it was sent. Banks can see deposits that were rejected or returned, which happens if the account number or routing number on your return was wrong, the account was closed, or the account holder's name did not match the return. If the deposit was rejected, the IRS will reissue the refund as a check, which takes an additional two to three weeks. The IRS will send you a letter explaining the rejection.

For check refunds, wait 21 days from the date the IRS says the check was sent before assuming it is lost. Checks can take up to three weeks to arrive by mail. If 21 days have passed, call the IRS and ask them to issue a replacement check. The IRS will verify that the original check was not cashed, then send a new one. This process takes another two to three weeks.

What to do if the IRS requests documents or verification

If the IRS sends you a notice requesting documents, respond as soon as you receive it. The notice includes a deadline — usually 30 days from the date of the letter. If you miss the deadline, the IRS may deny your refund or reduce it. Send the requested documents by the method the notice specifies: mail, fax, or online upload through your IRS account.

Common requests include proof of income (W-2s, 1099s, pay stubs), proof of expenses (receipts, invoices), proof of dependent status (birth certificates, Social Security cards), or proof of identity (driver's license, passport). If you no longer have the documents, explain that in writing and provide what you do have. The IRS will work with you, but the process takes longer.

If you are unsure whether the letter you received is real, verify it by calling the IRS directly. Scammers send fake IRS letters to trick people into sending money or personal information. A real IRS letter has a specific notice number, your name and address, and a phone number you can call to verify. The IRS will never ask you to pay by gift card, wire transfer, or cryptocurrency.

Identity theft holds and how to resolve them

If the IRS suspects your return was filed fraudulently or your identity was stolen, they will place a hold on your refund and send you a letter. This is one of the longest delays — identity theft cases can take several months to resolve. The IRS will ask you to verify your identity, usually by providing a copy of your driver's license or passport and answering security questions about your personal history.

Once you respond with verification, the IRS will review your return to confirm it is legitimate. If they confirm it is yours, they will release the refund. If they determine that someone else filed a fraudulent return in your name, they will deny that return and you will need to file a corrected return. The IRS has a dedicated identity theft hotline: 1-800-908-4490. This line is faster than the general refund line for identity theft cases.

If you believe your identity has been stolen, also file a report with the Federal Trade Commission (FTC) at identitytheft.gov. The FTC will create a record of the theft and provide you with a recovery plan. This does not speed up your tax refund, but it protects you against future fraud.

Frequently Asked Questions

How long should I wait before calling about a delayed refund?

The IRS processes most returns within 21 days of filing. If you filed electronically and it has been more than 21 days, you can call. If you filed a paper return, wait up to 30 days. Calling before 21 days usually results in being told your return is still processing.

Can a tax professional or CPA call the IRS about my refund?

Yes, but only if you have given them power of attorney. You can authorize a tax professional to discuss your return with the IRS by filing Form 2848. Without this form, the IRS will not discuss your return with anyone but you.

What if the IRS says my refund was sent but my state says it has not been issued?

This usually means you are waiting for a state refund, not a federal one. The IRS and your state process refunds separately. Call your state revenue department to check on the state refund status. If both are delayed, you have two separate issues to track.

Can the IRS speed up my refund if I need the money urgently?

No. The IRS cannot expedite processing for any reason. If your return is held for review, it will remain on hold until the review is complete. If you need money immediately, you may have other options, but the IRS refund timeline cannot be changed.

What if I filed my return but never received a confirmation?

Call the IRS and provide your Social Security number and filing status. They can tell you whether your return was received. If it was not received, you will need to file again. If it was received but you lost the confirmation number, the IRS can provide it.
