Estimated Payment Requirements
In general, a C corporation must remit Colorado estimated tax payments if its net Colorado tax liability for the tax year exceeds $5,000. For more information, review the Corporate Income Tax Guide.
Partnerships & S Corporations
Partnerships and S corporations (also referred to as “pass-through entities") may file composite returns on behalf of some or all of their nonresident partners and shareholders. Pass-through entities are not required to make estimated payments, but individual partners and shareholders included in a composite return may be subject to the estimated payment requirements if their individual Colorado income exceeds $1,000.
Pass-through entities may use the Composite Nonresident Estimated Tax Payment Form (DR 0106EP) to remit payments on behalf of any nonresident partner or shareholder included in a composite who is subject to estimated payment requirements. For additional information, see the FYI Income 51 guidance publication.
Business Income Reported on Individual Income Tax Returns
Generally, an individual or married couple filing jointly must remit Colorado estimated tax payments if their total Colorado tax liability, less withholding and credits, exceeds $1,000. For more information, visit the Individual Income Tax Estimated Payments web page.

How to Make Estimated Payments
Estimated tax payments must be submitted in the same manner, whether separate, consolidated or combined, and using the same account number that the corporation expects to use when filing the Colorado corporation income tax return. For more information, see publication FYI Income 51.
Partnerships & S Corporations
Estimated tax is the method used to pay tax on income that is not subject to withholding. Individuals who are not residents of Colorado (nonresidents) must pay tax on any Colorado-source income. This is intended for nonresident individuals who are included in a partnership or S corporation composite filing. In most cases, you will pay estimated tax if an individual partner expects to owe more than $1,000 in net tax for the year, after subtracting any withholding or refundable credits they might have. This rule must be calculated for each individual included in the composite return, and not as the composite as a whole. Use the Partnerships and S Corporation Estimated Payment Form (DR 0106EP) to submit your business' estimated payments.
You may also use Revenue Online to submit your partnership or S corporation estimated payments.
In most cases, a C corporation is required to pay estimated tax if it can reasonably expect the net tax liability will exceed $5,000 for the year. For taxpayers with a short taxable year, please see FYI Income 51 for more information. C corporations use the C Corporation Estimated Payment Form (DR 0112EP).
