Connecticut State Department of Revenue Services

Walk-in services at all DRS branch office locations remain suspended. Email DRS at drs@po.state.ct.us. Email the Priority One Taxpayer Assistance Program: DRSPriorityOne_CollectionsAssist@po.state.ct.us. Please check our Frequently Asked Questions page.

To pay by mail: Make your check or money order payable to the "Commissioner of Revenue Services."
Mail the check to DRS using the address found on the business return you are paying for.

Remember: To avoid penalty and interest, your balance must be paid on or before the due date of the return. To be timely, the check must be received or must bear a U.S. postmark on or before that date.

If you filed electronically DO NOT SEND a copy of the return with your payment.

You can always make a payment through the TSC-BUS, the Department's secure online filing and payment system.
