Contact Information

Enter your name and other contact information as required.

User Profile

First time users of the TSC must create a user profile which includes a User ID and password and must answer two identity questions.

The User ID is chosen by the user. Once created, it cannot be changed. Your User ID will be required for all future filings.

The password is case sensitive and must be between 6 and 30 characters long. The password must contain at least two of the following character types: letters; numbers; special characters. The two identity questions and answers will enable you to enter the TSC in the event you forget your password.

STORE YOUR USER ID AND PASSWORD AND KEEP IT IN A SAFE PLACE.  YOU WILL NEED TO ENTER THESE EACH TIME YOU LOGIN TO THE TSC.

On subsequent visits to the TSC, you will simply enter your tax registration number on the TSC Welcome page and then enter the User ID and password you have created on the next web page.

Main Menu

From the main menu, depending on your access rights, you may do all or some of the following:

  • File Returns

  • View Returns and Payment History

  • Make Payments

  • Make Changes to the Business Profile

The TSC Administrator for your business assigns the access rights. If you have any questions about your rights, you must contact your TSC Administrator.  See Administrator Contact on the left hand toolbar of the TSC main menu page. (DRS personnel cannot assist you with changing your access rights.)

You can also update your password/profile by clicking on the link on the left hand toolbar of the TSC main menu page.

Add/Update Users

IMPORTANT: TO AVOID LATE RETURNS OR PAYMENTS, WE STRONGLY RECOMMEND THAT THE TSC ADMINISTRATOR CREATE AT LEAST ONE SUB-USER TO FILE AND PAY RETURNS IN THE EVENT OF HIS OR HER UNEXPECTED ABSENCE. 

IF THE TSC ADMINISTRATOR IS THE ONLY PERSON WITH THE RIGHT TO FILE AND PAY, NO ONE ELSE WILL BE ABLE TO PERFORM THESE FUNCTIONS USING THE TSC IF THE ADMINISTRATOR IS NOT AVAILABLE.  THIS PROBLEM WILL BE AVOIDED IF YOU CREATE A SUB-USER AS BACK-UP. 

FOR SECURITY PURPOSES, DRS WILL NOT BE ABLE TO GIVE ACCESS TO THE ACCOUNT TO ANYONE ELSE IN THE ADMINISTRATOR'S ABSENCE.

The TSC Administrator for the business will have the ability to create other “sub-users” within the business and provide these sub-users with different access rights in the TSC.  For example, the TSC Administrator could designate one sub-user in the business to file returns and another sub-user to make payments.

The levels available for assignment are:       

  • View Only - User has rights to view returns, payments, and cancelled payments.

  • File Only - User has rights to prepare, save, and submit a return and receive a confirmation.

  • Pay Only - User has rights to make a payment, cancel a payment, and view history.

  • File and Pay - User has rights to file and pay, cancel a payment, and view history.

  • No Access - User has no rights for this tax type.

To add a new user, click on the Add User button.

Edit Current Users: The TSC Administrator can also add new rights or remove all or some of the rights from current users.  To edit the rights of current users, click on the name of the user below. 

Unlock User

The TSC Administrator for the business is the only one that has the ability to reset and unlock the passwords for other TSC users for that business. DRS cannot unlock the password for these users.

To unlock a TSC User, the TSC Administrator MUST go the Status Box and change the status in the drop down menu from "locked" to "active". 

If the user also forgot his or her password, the TSC Administrator may:

  • Manually enter a temporary password for the user by checking "Generate Temporary Password" box and typing the password in the  Password Box.  The temporary password must be 6-10 characters long and must contain both letters and numbers.  The password is case sensitive; or

  • Click on Generate Temporary Password button to have the system choose a password. 

  • Provide the temporary password to the user. 

  • The user must enter this temporary password the next time he or she logs into the TSC and will then be prompted to create a new password.

Add User

The TSC administrator may create accounts for other users of the TSC by following these steps:

  • Enter a User ID for the new user.  DRS recommends using a User ID that the user will remember, such as the user's last name and first initial.  Write down the User ID and give it to the new user. 

  • Type in the User ID - This is just for identification purposes and is not used in the login process.

  • Generate Password: Either enter a temporary password or click on "Generate Temporary Password" to let the system create it.  Be sure to give the temporary password to the new user.  The new user will be prompted to create his/her own password when they log into the TSC for the first time.

  • Assign User Rights: Select the user's rights from the drop down boxes.  You must select the user's rights for each tax type for which the business is registered.  Access Level Descriptions are provided at the bottom of the Add User page.

  • Select the Save button.

Edit User

The TSC Administrator can:

  • Activate or Disable users.  To activate or disable a user, scroll down to the Status drop-down box and make the selection.

  • Change the access rights of users. To change access rights, scroll down to User Rights and make the changes in the drop down box(es).

  • Assign Administrator rights to another user.  To temporarily (or permanently) assign your rights as Administrator to another user, scroll down to User Information, and check the "This user is the Administrator" box.  Remember, there is only ONE TSC Administrator per Connecticut Tax Registration Number.  If you make this user the Administrator, you will no longer have those rights.

NOTE on Balance Due: If a return for any of the periods listed below has not yet been filed, the balance due column may not be accurate.  Once the return for the period has been filed and processed, the balance will be updated.  For example: if you did not file a return for the Period End 7/31/18 and DRS mailed you a delinquency notice, the Balance Due column will not show the correct amount due because you have not yet reported what you owe; instead it will show $0.   If you are not certain whether you filed a return for any period, return to the Main Menu and select View Returns.

Penalty Waiver

All tax and interest must be paid before requesting a waiver of the penalty.  Be sure to view your balance due before submitting your request.  If tax and/or interest is due, submit your payment first and do not submit your penalty waiver until that payment has been processed.  Interest cannot be waived and must be paid before your penalty waiver request can be reviewed.  It is recommended that you allow two months for a reply from the Penalty Waiver Unit.  If you have not received a reply at that time, please call the Penalty Waiver Unit at 860-297-4944.

Third Party Bulk Filer

Third Party Bulk Filers (TPBF) are tax preparers or others that have requested and been assigned by DRS the capability to file tax returns on behalf of other taxpayers. If you have been assigned the access rights of a TPBF, you will have the option to key in the information for one client at a time, upload a file for multiple taxpayers, or submit a combined filing for multiple withholding tax payments (CT-WH) for your clients with a single logon using the same bank account.  To become a TPBF, contact the Electronic Commerce Unit (ECU) at 860-297-4973.

Refund Status

Explanation of Refund Status Terms:

 
PROCESSED: Your return has been processed and your refund will be issued in a few days. If you requested Direct Deposit you must allow two-three business days before the refund reflects in your bank account.  Please check your bank statement or call your bank after two-three business days from processed date. (Direct Deposit refunds are not immediately reflected in your account.)

UNDELIVERABLE: Your refund was processed by DRS but was undeliverable because of a problem with your mailing address in our records. Please contact DRS between 8:30 am and 4:30 pm Monday through Friday by calling 860-297-5962.

MODIFIED: The amount of your refund has been modified for one of the following reasons:  a mathematical error was corrected, it was applied to an existing tax bill, or it was offset to pay an outstanding liability to the Internal Revenue Service or another Connecticut State Agency, or after processing your return it was determined that additional information is needed for the Earned Income Tax Credit you are claiming.  You will receive written notification within ten days of your return being processed explaining the reason for modification.

UNDER REVIEW: Your return is currently being reviewed.  If your return was electronically filed more than ten days ago be sure to check that the Department has not sent you correspondence asking for additional information we need from you.  (e.g.  EITC additional info letter, Refund Protection Notice).  You must follow the instructions on the notice before we can further process your return.

If you mailed your return more than twelve weeks ago, please contact DRS at 860-297-5962.

What is a status letter?

The Department of Revenue Services (DRS) issues a status letter (also known as a Letter of Good Standing) to a business, upon request, provided certain conditions or criteria are satisfied.

If DRS determines it is appropriate to issue a status letter, the letter will contain the following information about a business as of the date it is issued:

  • The name of the entity,

  • That they have filed all of its tax returns and,

  • That they paid all taxes that were reported due.

Note: DRS does not make any representations that it has conducted an audit examination or otherwise concluded that the information reported on the tax return(s) is correct.

This is not a Tax Clearance Certificate under Connecticut General Statutes §§ 12-294, 12-424, 12-546, or 12-707.
