This is from an August communication that the CT Department of Revenue sent out regarding how Connecticut business owners will file returns, make payments, etc. starting September 21, 2020.  If you have any questions, please contact our offices:

The Department of Revenue Services (DRS) is currently undergoing a multi-year, multi-phase information technology (IT) modernization initiative. As part of the initiative, the DRS will begin replacing the Taxpayer Service Center (TSC) with myconneCT, a new, safe, secure, and user-friendly online system.

Beginning Monday, September 21, 2020, taxpayers will use myconneCT to file returns, make payments, view filing history, and communicate with the agency regarding the following taxes:

  • Sales and Use / Business Use
  • Withholding
  • Room Occupancy (B&B Occupancy)
  • Prepaid Wireless E 9-1-1 Fee
  • Admissions and Dues
  • Tourism Surcharge
  • Rental Surcharge
  • Dry Cleaning Surcharge
    IMPORTANT: In preparation for this transition, effective Wednesday, September 2, 2020, the tax types listed above will be disabled in the TSC; however, the TSC will continue to accept required payroll and non-payroll payments (CT-WH and CT-8109) through the end of September.

Only the above tax types are impacted at this time. Taxpayers who do not file or pay any of the tax types listed above are not impacted at this time, and should continue using the current method of filing.

Taxpayers filing both Phase 1 tax types and non‑Phase 1 tax types (e.g. Corporate Income Tax) will be required to use myconneCT for Phase 1 tax types and should continue to use the current method of filing for non-Phase 1 tax types.

Balances displayed in myconneCT only represent the balances for Phase 1 tax types (listed above).
Separate bills for Phase 1 and non-Phase 1 tax types will be issued. Together, these will provide the taxpayer with a “full picture” of their financial status with the agency.
Estimated assessments will occur on all delinquent returns in myconneCT.

Estimated assessments will be processed based on the best available information including, but not limited to: previous filing history, tax type, filing frequency, and industry classification.
Taxpayers receiving an estimated assessment should not send in payment for the estimated tax due. Instead, taxpayers should file the return and pay the actual tax due amount, if any, by the protest expiration date.
Helpful resources, such as Frequently Asked Questions (FAQs) and tutorials, are available online: portal.ct.gov/DRS-myconneCT

When myconneCT goes live, a dedicated hotline will be available with DRS staff ready to assist.
Stay safe!

Sincerely,
Connecticut Department of Revenue Services
