How to Pay Connecticut State Taxes Online?

Connecticut residents, nonresidents, and partial-year residents who earn income within the state must file an annual Connecticut income tax return. Connecticut taxpayers can choose to have their refund directly deposited into their bank account or pay taxes online using credit, debit, or an e-check. Whether you are filing a return with a refund or paying tax, you must include all supporting documents with your payment. You must also keep copies of your return and any completed worksheets or schedules for your records. Keep these until the statute of limitations expires for that return, typically three years from the filing date.

Connecticut State Tax Payment Process

Individuals can file and pay their Connecticut state taxes online using myconneCT, the official portal for filing, paying, and managing state tax responsibilities. In addition, they can pay through the state’s Taxpayer Service Center. This option allows them to authorize a direct transfer from their bank account, and it’s available at any time of the year. Those who need to pay by check can write the check or money order to the Commissioner of Revenue Services and address it to PO Box 2977, Hartford, CT 06102.

To make a payment by check, write “2024 Form CT-1040” and your social security number (SSN) or individual taxpayer identification number (ITIN) on the front of the check. If you are filing a joint return, both spouses’ SSN or ITIN numbers must be written on the check. You must also fill out a Direct Deposit Authorization Form to have the refund directly deposited into your bank account.

You must use the same taxable year for Connecticut income tax purposes as you used for federal income tax purposes. If you change your taxable year or method of accounting for both Connecticut and federal income tax purposes, you must file an amended return. If you are a nonobligated spouse, you may claim your share of a joint refund by filing Form CT-8379, Nonobligated Spouse Claim.

The time for having an overpayment of Connecticut income tax refunded or credited expires three years after the date your return was due, or the date you filed your return, if later. If you are a legally disabled person, the time for having an overpayment of Connecticut income refunded or credited is extended for as long as you remain financially disabled.
