Welcome New Business
Thank you for registering your business with our Department. We appreciate your cooperation and look forward to serving you. The primary mission of the Department of Revenue Services is to administer the tax laws of the state. We seek to achieve the highest level of voluntary compliance by providing helpful information on your tax obligations and online options.
Please use the links provided under Taxpayer Service Center (TSC) to access electronic options and Tax Information to Assist You to obtain valuable tax information.
Access electronic options using the Personal Identification Number (PIN) that DRS has assigned to you. Connecticut business taxpayers can electronically file most Connecticut business tax returns and make direct tax payments using the Taxpayer Service Center (TSC-BUS). The TSC-BUS is an interactive tool that provides a free, fast, easy, and secure way to conduct business with DRS. Some of the features of the TSC include the ability to securely file, pay, and manage your tax accounts.
If you choose to file on paper and you are not mandated to file electronically, you may visit the DRS Forms Page to download the form you need.
