If Connecticut’s “Where’s My Refund?” tool shows your CT tax refund under review, it means the Department of Revenue Services (DRS) pulled your return out of automated processing to verify something before releasing the money. It’s not an accusation, and it’s not rare. DRS screens every return for errors, fraud indicators, and mismatches with third-party records, and thousands of legitimate returns get flagged each filing season. The review usually adds weeks, sometimes months, to your wait. What you do next depends on why it was flagged.
Why DRS Flagged Your Return
Most reviews start with a discrepancy between your return and data DRS already has. The single most common trigger is a mismatch between the income, withholding, or credits on your Form CT-1040 and the W-2 or 1099 information your employer or payer filed with the state. Filing early, before employers submit wage reports, is a frequent cause. So is a typo in a withholding box. DRS will not release a refund based on withholding it cannot verify, and it will disallow your Connecticut withholding entirely if you fail to complete all required columns in Section 3 of your return.1Connecticut Department of Revenue Services.

Returns claiming certain credits draw extra scrutiny. The Connecticut Property Tax Credit, currently worth up to $300 and phasing out at higher income levels, requires proof you actually paid property tax to a Connecticut municipality.2Connecticut Governor’s Office. Governor Lamont Proposes Additional Tax Relief The Connecticut Earned Income Tax Credit, a percentage of your federal EITC, is another frequent flag because small changes in reported earnings can shift eligibility.3Connecticut State Department of Revenue Services. CT Earned Income Tax Credit
Estimated tax payment errors are another common cause. If the quarterly payments you reported don’t match what DRS has recorded, the refund holds until the numbers reconcile. Part-year and nonresident returns get flagged more often too, because residency controls which income Connecticut can tax and the allocation has to be right.
Identity Verification Holds Are Different
If DRS suspects someone may have filed using your identity, the hold works differently. Connecticut runs a dedicated verification system that asks you a short series of questions to prove you are who you say you are. Answer correctly and the refund moves forward. Miss some, and you may get a second set of questions. If you can’t pass, the refund stays frozen until the DRS Fraud Prevention Unit works with you directly to confirm your identity.4Connecticut Department of Revenue Services. DRS Refund Verification
First-time Connecticut filers, people who recently moved to the state, and taxpayers who switched from paper to electronic filing are the most likely to land here. The system tends to flag returns tied to a Social Security number with no recent Connecticut filing history.
When the Refund Was Taken for a Debt
Sometimes the status reads as a review but the real story is an offset. Connecticut law requires DRS to intercept your refund if you owe money to another state or federal agency. When that happens, your refund (or part of it) goes to the agency instead of to you. Common reasons include unpaid Connecticut income tax from a prior year, overdue child support, and debts submitted through the federal Treasury Offset Program.5Connecticut Department of Revenue Services. Treasury Offset Program
DRS mails a written notice showing your original refund, the amount taken, which agency received it, and that agency’s contact information. If the entire refund was intercepted, that explains why your status may never move to “Approved.” A dispute over the underlying debt belongs with the agency that claimed the money, not with DRS.5Connecticut Department of Revenue Services.

How Long the Review Takes
Once a return is flagged, a tax examiner compares what you reported to third-party records such as federal filings, W-2s, and 1099s. If the examiner can clear the discrepancy internally, the hold lifts and the refund processes without you hearing anything. If the examiner needs something from you, DRS mails a letter to the address on your return explaining exactly what.
DRS does not publish a timeline for manual reviews. It does publish that paper returns take 10 to 12 weeks under normal conditions and asks that you not call before 12 weeks have passed if you filed on paper.6Connecticut State Department of Revenue Services. Check the Status of Your Income Tax Refund Electronic returns are faster in the ordinary course, but a review can push either type well past those windows. The practical range for reviewed returns is six to twelve weeks, and cases involving identity verification or missing documents can run longer.
The clock effectively stops whenever DRS is waiting on you. If they mail a letter requesting documents, the timeline doesn’t resume until they receive everything they asked for. Incomplete responses or documents sent to the wrong address restart the wait.
What to Send If DRS Writes to You
The notice itself will spell out what’s needed, but the common requests are:
- Copies of all W-2s and 1099s, especially if the withholding is in question.
- A complete copy of your federal Form 1040, including all schedules.
- Cancelled checks or bank statements proving quarterly estimated payments to Connecticut.
- Residency proof such as utility bills, a lease, or mortgage statements if Connecticut residency is being questioned.
- Municipal tax bills or payment confirmations if you claimed the Property Tax Credit.
Make sure every copy is legible and that the figures match your return. Include a copy of the DRS notice so your documents reach the right examiner, and use the specific mailing address printed on the notice.
You can also upload documents through the myconneCT portal, which is DRS’s online system for filing, payments, and communication with the department. Electronic submission is faster than mail and gives you a confirmation of receipt. The portal has a secure messaging feature if you need to communicate with an examiner.7Connecticut Department of Revenue Services. About myconneCT

If DRS Reduces or Denies the Refund
If the review ends in a reduction or denial, DRS must mail a “notice of proposed disallowance” that explains the reasons and the adjusted amount. You have 60 days from the date on that notice to file a written protest with the Commissioner of Revenue Services. The protest has to spell out the specific grounds for your disagreement. If you request it, the Commissioner may grant an oral hearing.8Justia Law. Connecticut Code Title 12 – Section 12-732
After reviewing the protest, the Commissioner issues a written decision with findings of fact and reasoning. That decision becomes final one month after it is mailed unless you seek judicial review under Connecticut General Statutes ยง 12-730 within that window.8Justia Law. Connecticut Code Title 12 – Section 12-732 Missing the 60-day protest deadline is costly: the proposed disallowance becomes final automatically and you lose the right to challenge it administratively.
You have the right to be represented by a tax professional or attorney during any interaction with DRS, to receive a clear written explanation of any adjustment, and to seek review of adverse decisions through formal or informal proceedings.9Connecticut General Assembly.

When to Call the Taxpayer Advocate
If you’ve been going back and forth with DRS and the normal process isn’t moving, Connecticut maintains a Taxpayer Advocacy Office for exactly this situation. The advocate’s role is to help resolve problems the regular channels have not fixed. Write to the Taxpayer Advocacy Office, Department of Revenue Services, 25 Sigourney Street, Hartford, CT 06106.10Connecticut Department of Revenue Services. TSSN-45, Your Rights as a Connecticut Taxpayer The office cannot help with cases already in litigation or under active enforcement, but a stalled review is squarely within its purpose.
Interest When DRS Holds the Money Too Long
Connecticut pays interest on refunds held past a certain point. Interest accrues at 0.75% per month beginning on the 91st day after DRS received your refund claim, or the 91st day after the filing deadline, whichever is later.11Justia Law. Connecticut Code Title 12 – Section 12-227 That runs roughly 9% annually, and it continues until DRS issues the refund. Any period in which DRS was waiting on documents from you is not counted in your favor.
