Please remember that you must claim the state sales tax refund (TABOR refund) when filing your state income tax return. If you claimed a 2023 refund, the TABOR refund will be combined and issued out with your refund. Unlike the 2022 Colorado cashback, no separate check will be issued. 


DR 0233 - 2023 Computation of Penalty Due Based on Underpayment of Colorado Estimated Tax for a Partnership and S Corporation Making a SALT Parity Act Election


This form should be included with your completed DR 0106 form. A partnership or S corporation that has made a SALT Parity Act election is subject to the same requirements for estimated tax payments as C corporations. In general, an electing partnership or S corporation must remit four quarterly estimated tax payments if its net Colorado tax liability for the tax year exceeds $5,000. The electing partnership or S corporation can calculate its estimated tax payments based on its net tax liability for the preceding year only if it made a SALT Parity Act election for that preceding tax year.
