After IRS Code 971 appears on your transcript, most refunds arrive within two to ten weeks, but the actual timing depends entirely on the notice behind the code and whether you have to respond to it. A simple math correction can clear in two to four weeks with no action from you. An identity verification or credits audit can stretch past two months, and only starts moving once you reply. The 971 itself is not the delay; the letter it points to is.
What Code 971 Is Telling You
TC 971 is a general-purpose administrative code the IRS uses when it sends a notice or records certain actions on your account. It is not a denial, an adjustment, or an audit flag on its own. Dozens of different situations can trigger it, from a corrected math error to an installment agreement confirmation to an identity check.
The date next to TC 971 is the posting date, which is roughly when the IRS generated and mailed the letter. Allow about 10 to 14 days from that date for the paper copy to arrive. If you have an IRS Individual Online Account, the notice often appears there before the mail catches up. The notice number printed on that letter (CP05, CP12, CP75, 5071C, CP49, and so on) is the single best predictor of how long your refund will actually take.
How Long Each Notice Typically Takes
CP12: Two to Four Weeks
A CP12 says the IRS found and corrected a math mistake, and your refund amount changed as a result.1Internal Revenue Service. Understanding Your CP12 Notice If you agree with the correction, you do nothing. The adjusted refund usually processes within two to four weeks of the notice date. Disagreeing and contacting the IRS adds time.
CP49: About Three Weeks for Any Remainder
A CP49 means the IRS applied all or part of your refund to a tax balance from a previous year.2Internal Revenue Service. Understanding Your CP49 Notice The refund can also be offset against past-due child support, federal student loans, and other government debts. If any refund is left after the offset, expect it within about three weeks. If your spouse’s debt caused the offset and you weren’t responsible for it, Form 8379 (Injured Spouse Allocation) lets you claim your share.
CP05: Up to 60 Days, Sometimes Longer
A CP05 means the IRS is taking extra time to verify your income, withholding, or credits before releasing the refund. You don’t need to do anything. The IRS specifically instructs taxpayers not to call until 60 days have passed from the notice date without receiving a refund or further correspondence.3Internal Revenue Service. Understanding Your CP05 Notice If the review continues, the IRS may follow up with a CP05A requesting specific documents such as wage records or withholding statements. After you send those in, expect up to another 60 days.
5071C or CP5071: Four to Nine Weeks After You Verify
This letter means the IRS flagged your return as potentially fraudulent and needs you to confirm your identity before it will process the return. Verify online at irs.gov/verifyreturn or call the number on the notice, with your tax return and supporting documents ready.4Internal Revenue Service. Understanding Your CP5071 Series Notice Your refund does not move until verification is complete.5Taxpayer Advocate Service. Identity Verification and Your Tax Return Once verified, most refunds release within four to nine weeks.
CP75: Six to Ten Weeks After You Respond
A CP75 is more serious. The IRS is auditing your return, typically to verify eligibility for credits like the Earned Income Tax Credit. You must send the requested documentation by the deadline on the notice, or the IRS proceeds with proposed changes to your return.6Internal Revenue Service. Topic No. 654, Understanding Your CP75 or CP75A Notice These reviews commonly take six to ten weeks after documents are submitted, and sometimes longer during peak filing season.
Reading the Codes Around 971 on Your Transcript
When TC 971 is tied to a refund delay, it usually appears alongside other codes that show exactly where you stand.
- TC 570 (Additional Account Action Pending) is the actual hold on your refund. If your transcript shows 971 without 570, the notice may be informational only and the refund can still process normally.
- TC 571 (Resolved Additional Account Action) means the hold has been lifted.
- TC 846 (Refund Issued) is the finish line. The date beside it is when Treasury scheduled the payment. Direct deposits typically arrive within one to three business days of that date; paper checks take longer.
The gap between TC 571 and TC 846 is usually one to two weeks. The real bottleneck sits between TC 570 and TC 571, which is either the IRS waiting on your response or working through its own review. Where’s My Refund only shows Return Received, Refund Approved, and Refund Sent, and lags behind the transcript, so the transcript is where the useful detail lives.7Internal Revenue Service.

If You Claimed EITC or ACTC
Returns claiming the Earned Income Tax Credit or the Additional Child Tax Credit are held by law until mid-February, even if filed in January.8Internal Revenue Service. When to Expect Your Refund if You Claimed the Earned Income Tax Credit or Additional Child Tax Credit The hold applies to the full refund, not just the credits portion. A TC 971 showing up in January or early February on one of these returns may simply reflect that mandatory hold rather than any problem with your return. Neither the IRS nor the Taxpayer Advocate Service can release these refunds early, even for financial hardship.9Taxpayer Advocate Service. Held or Stopped Refunds
How to Keep the Delay as Short as Possible
Failing to respond to the notice is the single biggest reason refund delays stretch from weeks into months. The IRS will not lift the hold until it gets what it asked for.
Read the letter first. Check your IRS online account for a digital copy, or wait for the paper letter to arrive. If it never shows up, call the IRS at 800-829-1040 to request another.10Internal Revenue Service. Understanding Your IRS Notice or Letter
Respond by the deadline. Most notices give you 30 to 60 days. If you need more time to gather documents, call the number on the notice before the deadline rather than letting it lapse. After you respond, allow at least 30 days for the IRS to process what you sent before following up.11Internal Revenue Service. Topic No. 651, Notices – What to Do
If the notice requires no action (a CP05, or a CP12 where you agree with the correction), don’t call early. Wait the full timeframe the notice states. Calling before then doesn’t speed anything up.
When It Has Gone On Too Long
The Taxpayer Advocate Service is an independent organization within the IRS that steps in when the normal process breaks down. You’re not meant to contact them the moment TC 971 appears. But if your refund has been held for an extended period and you’ve already responded to every notice, or if the delay is causing genuine financial hardship such as an inability to pay rent or medical bills, TAS can intervene.
Request assistance by filing Form 911. If you don’t hear back within 30 days, call TAS at 877-777-4778.12Internal Revenue Service. Form 911, Request for Taxpayer Advocate Service Assistance TAS is especially useful when you’re stuck in a loop: the IRS sent a notice, you responded, weeks passed, and your transcript still shows TC 570 with no TC 571 in sight. That pattern usually means your response wasn’t properly matched to your account, and a case advocate can trace where the breakdown happened.
Interest the IRS Owes You
If the IRS holds your refund more than 45 days past the filing deadline (or 45 days from your filing date if you filed late), it owes you interest on the delayed amount. The interest accrues automatically; no separate claim is needed. It compounds daily and gets added to the refund when it’s finally released.
For the first quarter of 2026, the interest rate on individual overpayments is 7% per year, compounded daily.13Internal Revenue Service. Interest Rates Remain the Same for the First Quarter of 2026 Starting April 1, 2026, the rate drops to 6%.14Internal Revenue Service.
