For tax years beginning on or after January 1, 2024, partnerships and S corporations must remit quarterly estimated payments if their net Colorado tax liability for the year with a nonresident composite return exceeds $5,000. The rules for calculating a partnership’s or S corporation’s required estimated payments are generally the same as the rules for calculating a C corporation’s estimated tax payments. Please see Part 9 of the Colorado Corporate Income Tax Guide for additional information.
For information about payment methods, please visit Tax.Colorado.gov/pay.
For computation of the penalty based on underpayment of Colorado estimated tax, please see form DR 0233.
