Connecticut State Tax Refund: Status, Timing and Delays

Connecticut refunds are handled by the Department of Revenue Services (DRS). The department publishes one status page, an automated phone line and a short list of reasons a refund can be held, offset against a debt or sent as a paper check. This guide puts those rules in one place and says where the department has not given a number.

It is based on the DRS refund status page, the DRS filing season FAQ (marked reviewed 5 December 2025) and the DRS resident income tax pages for 2025 returns ("Other Helpful Information" and "Tax Information"), all read on 2 November 2026. DRS writes these pages for the current filing season and updates them each year, so check the live pages for the season you are in. We cannot see your return or your refund; only DRS can.

How to Check Your Connecticut Refund Status

The department gives two routes, and both ask for your Social Security number (the primary number if it is a joint return and your spouse's number is entered first) and the exact amount of the refund as reported on your Connecticut return. The online tool also has you choose the tax year; the phone instructions do not mention a tax year.

• Online: open myconneCT, go to the Welcome Page and select the Where's my Refund? link on the Individuals panel. Enter the whole dollar amount you requested, without cents. DRS gives the example that a $375 refund request is entered as 375.
• Telephone: the automated refund system runs 24 hours a day on 860-297-5962 from anywhere, or 800-382-9463 for Connecticut calls outside the Greater Hartford calling area only. On the phone you enter the whole dollar amount followed by the # sign. DRS says that by telephone you can only check the refund for the current filing season.

The number you enter must be the amount on the return, so copy it from your filed return.

How Long a Connecticut Refund Takes

DRS does not publish a processing time for electronically filed returns on the pages we read, so we do not give one. On its Tax Information page DRS says paper filers must allow 10 to 12 weeks from the date the return was mailed before checking on the refund. What it does state:

The table is our arrangement of the department's statements, not a department table.

What Can Delay or Redirect a Refund

The pages we read name these causes. They do not give a complete list of review triggers, and DRS does not say how long any of them adds.

• Suspected fraud. If DRS suspects a return was filed fraudulently, it says the refund request will be delayed while it confirms with the taxpayer that the filing and the request are legitimate. Where it finds a high probability of fraud, it ignores a direct deposit request and issues a paper check. If you receive a refund before you have filed, DRS asks you to contact its Fraud Unit at 855-842-1441.
• Debts. DRS states that a refund due to you from the IRS or the State of Connecticut will be applied to your bill if you owe the department, even if you have an established payment plan, and that the refund is not treated as your monthly instalment.
• Identity checks. DRS says a refund could be delayed if additional information or identity verification is required to prevent refund theft.
• Choosing a paper check. Not electing direct deposit, or being a first-time filer, means a check is issued and processing may be delayed.
• A paper return. The 10 to 12 week period above.

Offsets Against Debts and a Spouse's Share

On a joint return where only one spouse owes past-due child support, a debt to any Connecticut state agency, or tax due to another state or the IRS, the spouse who is not obligated may be eligible to claim a share of the joint refund. DRS says that spouse claims it on Form CT-8379, Nonobligated Spouse Claim.

CT-8379 is not for a refund applied to a spouse's federal tax liability; DRS says to use the IRS telephone number on the Notice of Refund Offset for IRS offsets. The pages we read do not list which other debts DRS offsets beyond those named above, and do not give an order of priority.

If the Refund Has Not Arrived or Is Missing From Your Bank

DRS links a form for reporting a lost, stolen or missing refund check or direct deposit. In its FAQ, if DRS indicates the refund was direct deposited but your bank records do not show it, the answer is to complete Form CT-3911, Taxpayer Statement Regarding State of Connecticut Tax Refund, using myconneCT.

The order we suggest, which is ours rather than the department's: check the status tool for the tax year and exact amount; if the return was on paper, wait out the 10 to 12 weeks; then call 860-297-5962; if the status shows a deposit you cannot find, file CT-3911.

Amended Returns and the Time Limit to Claim a Refund

DRS says that generally the Connecticut statute of limitations for refunding or crediting an overpayment expires three years after the due date of the return. If a timely extension was filed, it expires three years after the extended due date or three years after the date of filing, whichever is earlier. A Form CT-1040X filed to get an overpayment refunded must be filed before the limit expires; the form's instructions list exceptions to the three-year limit.

If you have received a paper refund check and your liability will increase on an amended return: an uncashed check should be returned to DRS as soon as possible, with a letter explaining that an amended return will be filed. If you cashed the check, you must pay the amount due on the amended return. The pages we read give no processing time for amended returns, so we give none.

Interest on a Connecticut Refund

DRS says that if it does not issue your refund on or before the ninetieth day after it receives your claim for refund, you may be entitled to interest on your overpayment. Interest is computed at two thirds of one percent (2/3%) for each month or fraction of a month between the ninetieth day after DRS receives your properly completed refund claim, or the due date of your return if that is later, and the date of notice that your refund is due. DRS says interest is not paid on refunds from a PE Tax Credit claim.

This is DRS's description on its Tax Information page for 2025 returns. The refund status page links to an "Am I entitled to Interest on My Refund?" question, but the FAQ page it links to does not answer it, so check how DRS applies the rule to your refund.

Refunds Can Be Reportable on a Federal Return

DRS says Form 1099-G reports refunds, credits or offsets of state or local income tax, and that the amount reported includes the total overpayment from your Connecticut return. It adds that the amount may be subject to tax on your federal return and included in your Connecticut adjusted gross income. Whether it is taxable for you depends on your own return.
