The IRS can hold your refund for 30 days to several months while reviewing your return, depending on what triggered the review and how complex the issue is

When the IRS flags your return for review, there is no single answer to how long you will wait. A routine review — where the IRS double-checks math or verifies a deduction — often takes 30 to 60 days. A more involved examination, where the IRS requests documents or questions your income, can stretch to six months or longer. The clock starts when the IRS receives your return, not when they send you a notice.

The length depends on what the IRS is checking. If they are verifying a single item like a charitable donation, the hold is usually shorter. If they are examining multiple years of returns or investigating whether income was reported correctly, the review takes longer. The IRS also prioritizes cases — some get reviewed faster than others based on the type of issue and current workload.

Key Takeaways

  • Routine reviews typically take 30 to 60 days, while more complex examinations can take six months or longer.
  • The IRS will send you a notice in the mail if your return is selected for review; you do not find out through your bank or tax software.
  • You can contact the IRS during the review to ask for a status update, though they may not have new information yet.
  • If the IRS holds your refund beyond a certain point without resolution, you may be owed interest on the delayed amount.

What triggers a refund review and how the timeline works

The IRS reviews returns for several reasons: math errors, inconsistencies between your return and IRS records, claimed deductions that seem unusually large, or income that does not match what employers or banks reported to the IRS. When your return is selected, the IRS does not immediately release your refund. Instead, they set it aside and begin their examination.

The timeline depends on the type of review. An automated check — where a computer flags a discrepancy — can be resolved in 30 days if you respond quickly or if the IRS corrects the error on their own. A manual review, where an IRS employee examines your documents, typically takes 60 to 90 days if you provide what they ask for promptly. An audit, which is a formal examination, can take six months to over a year, especially if the IRS needs to request multiple rounds of documents or if your case is complex.

How the IRS notifies you and what to do when you receive a notice

The IRS always sends a notice by mail — never by email, text, or phone call. The notice will explain what they are reviewing and what documents or information they need from you. It will also include a deadline for your response, usually 30 days. If you miss the deadline, the IRS can proceed without your input, which often results in a smaller refund or no refund at all.

When you receive a notice, respond within the deadline even if you need more time. If you cannot gather the documents by the date listed, send a letter to the address on the notice explaining why and asking for an extension. The IRS often grants extensions if you have a legitimate reason. Keep copies of everything you send and send it by certified mail so you have proof of delivery.

Checking the status of your refund review

You can check the status of your return through the IRS website using the "Where's My Refund?" tool, though during a review it may show limited information. You can also call the IRS at 1-800-829-1040 and speak to a representative, though wait times are often long. Have your Social Security number, filing status, and the exact refund amount ready when you call.

The IRS representative can tell you whether your return is still under review, whether they have received your response to a notice, or whether a decision has been made. They cannot always speed up the process, but they can confirm that your case is moving forward and answer questions about what the IRS needs from you next.

What happens if the IRS takes longer than expected

If the IRS holds your refund for an unusually long time without resolution, you may be owed interest. Federal law requires the IRS to pay interest on refunds that are delayed beyond 45 days from the date you filed your return. The interest rate is set quarterly and is currently low, but it does accumulate. The IRS calculates and pays this interest automatically once your refund is issued — you do not have to request it.

If your refund has been delayed for several months and you have not heard from the IRS, you can file a complaint with the Taxpayer Advocate Service, which is an independent office within the IRS that helps resolve disputes. You can reach them at 1-877-777-4778 or through their website. They can investigate why your case is delayed and sometimes push it forward.

Reasons your refund review might take longer than typical

Some returns take longer to review because of the nature of the issue. If the IRS is examining self-employment income, rental property deductions, or business expenses, the review is more involved because these areas require more documentation. If you claimed a large refundable tax credit like the Earned Income Tax Credit, the IRS may review more carefully because these credits are subject to fraud. If you filed an amended return, the review can take longer because the IRS has to compare both the original and amended versions.

Staffing and workload also affect timing. During peak tax season, the IRS processes millions of returns and reviews move more slowly. If your case requires a specialist — for example, someone who handles business income — it may wait in a queue until that person is available. You cannot control these factors, but understanding them helps explain why your specific timeline may differ from someone else's.

What you can do while your refund is on hold

While the IRS reviews your return, you can still file future returns normally. Your current refund being held does not prevent you from filing next year's return. You should also continue to pay any taxes you owe during the review period — do not assume the review means you do not owe anything. If the IRS eventually determines you owe money instead of receiving a refund, they will send you a bill with payment instructions.

If you need the money urgently, you have limited options. You cannot force the IRS to speed up the review, but you can ensure you respond to any notices immediately and provide complete documentation the first time. The faster you respond, the faster the review can move forward. If you are facing financial hardship, the IRS has hardship programs, but these are separate from the review process and have their own requirements.

Frequently Asked Questions

Can the IRS hold my refund indefinitely?

No. The IRS must complete a review and issue a decision within a reasonable time frame. If a review drags on for over a year without resolution, you can contact the Taxpayer Advocate Service for help. The IRS also owes you interest if the refund is delayed beyond 45 days from your filing date.

Will I owe interest if the IRS delays my refund?

Yes, if the delay exceeds 45 days from the date you filed. The IRS pays interest automatically once your refund is issued. The rate is set quarterly and is currently low, but it does accumulate. You do not have to request it or file a separate claim.

What if I do not respond to an IRS notice about my review?

If you miss the deadline to respond, the IRS can close your case without your input. This often results in a reduced refund or no refund at all. If you miss the deadline, send a response anyway and explain why you were late. The IRS may reopen your case if you have a reasonable excuse.

Does a refund review mean I am being audited?

Not necessarily. A review and an audit are different. A review is usually automated or involves a quick check of one item. An audit is a formal examination and is more serious. The IRS will use the word "audit" in the notice if that is what is happening. Most refund reviews are not audits.

Can I get my refund early if I need the money?

No. The IRS will not release your refund until the review is complete. If you are facing financial hardship, you can ask the IRS about hardship programs, but these do not speed up the refund itself. Your best option is to respond to any IRS notices as quickly as possible to move the review forward.
