Payments with the extension request may be made by direct payment from a checking or savings account on the TSC-IND system or may be mailed in separately by check or money order. Extensions and payments made using the TSC will be timely as long as they are completed before midnight on the due date. Payments that are mailed to DRS must be timely filed following the guidelines for timely filing of a return.
IMPORTANT! YOU DON’T NEED TO FILE FOR AN EXTENSION IF BOTH OF THE FOLLOWING ARE TRUE:
- You expect to owe no additional Connecticut income tax for the taxable year, after taking into account any Connecticut income tax withheld from your wages or any estimated Connecticut income tax payments you have made, and any Pass-Through Entity Tax Credit (PE Tax Credit) you are entitled to claim, and
- You have requested an extension of time to file your federal income tax return. Keep a copy of your federal Form 4868 for your records.
A. The fastest and easiest way to file an extension request is to use the TSC-IND. If you use the TSC-IND to file the extension, do not mail anything.

Q. Can I use the credit card option to pay?
A. You may pay this year's Connecticut income tax liability using your Discover®, Visa, MasterCard® or American Express Card®. A convenience fee will be charged by the credit card service provider. You will be informed of the amount of the fee and you may elect to cancel your transaction. The total tax payment and convenience fee will be charged to your account by the credit card provider. At the completion of the transaction you will be given a confirmation number for your records.
To charge your Connecticut tax payment to your credit card:
- Visit www.officialpayments.com and select Payment Center. You will need to enter the Connecticut Jurisdiction Code: 1777.
Q. I know that I paid property tax but I am not sure how much I paid. What should I enter on the property tax schedule?
A. To claim the credit you must know the exact amount of property tax that you paid and must enter that amount on your Connecticut income tax return. You may contact your local town assessor’s office or visit the town website to view your property tax information online.
Otherwise, you may have to file your return and pay the tax you owe without claiming the credit and then amend to claim the credit after you know the exact amount. Or, you may request an extension of time to file.
