Taxpayer Service Center (TSC) Update

The TSC now accepts estimated payments electronically on Form CT-1065/CT-1120SI ES.

As a follow-up to prior DRS guidance and Special Notice SN 2018(4), Guidance on 2018 Estimated Payments for the Newly Enacted Pass-Through Entity Tax, taxpayers should note the TSC now accepts estimated payments electronically on Form CT-1065/CT-1120SI ES for tax year 2018.

To file online:

  • Go to the DRS homepage;
  • Click on the TSC logo;
  • Select the ‘For Businesses’ or ‘For Practitioners’ login button; and
  • Log into your business account (you must know your CT tax registration number, User ID, and TSC password).

If you do not have a CT tax registration number:

  • From left hand tool bar on TSC Welcome page, select ‘File/Pay Form CT-1065/CT-1120’; and
  • Follow the prompts.

For tax year 2018, you may also make estimated payments by coupon. Starting with tax year 2019, however, you must make payments electronically.
