If your tax return status shows Under Review in 2026, the IRS is double-checking the numbers you sent in. Refunds in this spot usually take 6–12 weeks to clear if everything checks out. While they’re looking things over, the IRS might ping you for extra paperwork or a quick explanation.
Quick Fix Summary
Hold tight. Most “Under Review” labels disappear in 6–12 weeks. Peek at your IRS account for updates, and reply fast if they ask for documents. Don’t bother calling unless your refund is way past the usual wait.
What’s going on behind the scenes?
When the IRS slaps an “Under Review” tag on your return, they’re either eyeballing it by hand or running an automated cross-check. Red flags can pop up from mismatched income, credits, or deductions—or you might just be the unlucky winner of a random audit lottery. The IRS technically has up to three years to dig deeper, but most reviews wrap up long before that. Even in 2026, the same 6–12 week window still applies unless they hit a snag.
Sometimes the IRS mails a CP05 notice asking you to prove your income, withholding, or credits. You’ve got a deadline in that letter—meet it or risk a refund freeze. If no letter shows up but the status is still “Under Review,” hop into your IRS account to see if they left a message you missed.
Here’s exactly what to do next
- Log in and look around
Fire up your IRS online account and scan the return status. If they want anything—like a missing form or extra receipts—it’ll show up under “Messages” or “Your Balance/Amount Due.” The IRS refreshes these notes daily, so swing by every few days.
- Answer the IRS immediately
Got a CP05 notice or an inbox message demanding documents? Round up the papers they asked for—W-2s, 1099s, deduction receipts—and send or upload them within the usual 30-day window. Skip this step and your refund could stall or shrink.
- Make sure your withholding matches reality
Run your numbers through the IRS Withholding Estimator to confirm your W-4 is still spot-on. Mismatches between what you reported and what your employer or bank sent the IRS are a top review trigger. Fixing this early can shave weeks off the wait.
- Watch the refund tracker like a hawk
After you drop off the paperwork, check your status again. If the review clears, your refund should pop out soon. If the label flips to “Still Being Processed,” the IRS might need more time for deeper digging or a system hiccup.
- Make the call if the clock runs out
Hit the 12-week mark with no refund? Ring the IRS at 1-800-829-1040 (or the number on your notice). Keep your tax return and any letters handy. Stuck in a maze of red tape? The Taxpayer Advocate Service can cut through the noise.
Still stuck? Try these moves
If “Under Review” lingers after you’ve sent everything they asked for, give these tricks a shot.
- Give the IRS a moment to catch up
Batch updates can lag a week or two. Wait another 1–2 weeks, then check again. If nothing budges, call the IRS to confirm they actually got your paperwork.
- Pull your transcript for a side-by-side
Grab a tax return transcript and line it up with your original filing. Any mismatches usually point right to the issue. If the IRS calls, you can email them the transcript to clear things up.
- Demand a higher-level look
When the IRS goes radio silent or the delay feels unfair, file Form 911 to rope in the Taxpayer Advocate Service. It’s free and built for taxpayers drowning in IRS delays.
How to dodge the “Under Review” label next time
Follow these habits and you’ll cut the odds of another review.
- File online and get paid fast
E-filing slashes typos that paper returns love to hide. Pair it with direct deposit and you can expect your refund in under 21 days if everything’s clean (IRS Statistics). In 2026, more than 90% of returns go this route.
- Proofread like your refund depends on it
Run your numbers through the IRS EITC Assistant and Child Tax Credit Calculator. Common trip-ups include the wrong filing status, inflated deductions, or missing schedules (hello, Schedule C for side gigs).
- Save everything for years
The IRS can audit up to three years after you file—longer if they smell fraud. Keep digital or paper copies of your return, W-2s, 1099s, receipts, and mileage logs. Neat files make reviews feel like a breeze instead of a panic.
- Use free IRS tools for bulletproof accuracy
Earn $79,000 or less? Use IRS Free File—it walks you through the maze and flags errors automatically. Don’t qualify? Free help is still out there: the IRS VITA program offers free prep for eligible taxpayers.
