Estimated Payment Deadline Extensions for Tax Year 2020
To provide relief to Connecticut taxpayers during the COVID-19 pandemic, the Connecticut Department of Revenue Services (DRS) extended the deadlines for the first and second quarter 2020 income tax estimated payments to July 15, 2020. Form CT-2210, Underpayment of Estimated Tax by Individuals, Trusts, and Estates, has been updated for the 2020 tax year to account for these deadline extensions. Ensure you are using the 2020 form to properly calculate the amount of interest due. You may use Form CT-2210 to calculate and report any interest due with your return. Alternatively, DRS will calculate interest on any underpayment of estimated tax and send you a bill.
