Pay by Credit Card or Debit Card
You may elect to pay your 2020 Connecticut income tax liability using a credit card (American Express®, Discover®, MasterCard®, VISA® ) or comparable debit card. A convenience fee will be charged by the service provider. You will be informed of the amount of the fee and you may elect to cancel the transaction. At the end of the transaction, you will be given a confirmation number for your records. Visit www.officialpayments.com and select State Payments. Your payment is effective on the date you make the charge.
Pay by Mail
Make your check payable to Commissioner of Revenue Services. To ensure proper posting of your payment, write “2020 Form CT‑1040” and your SSN(s) (optional) on the front of your check. Sign your check and paper clip it to the front of your return. Do not send cash. DRS may submit your check to your bank electronically.
