2024 Amended C Corporation Income Tax Return Instructions
You MUST use the amended return form that corresponds to the tax year you are
amending or your amended return cannot be processed.
The 2024 DR 0112X, Amended Colorado C Corporation Income Tax Return, is used to correct your
2024 C Corporation income tax return. File the return for free using Revenue Online. You can file on
paper if you cannot file electronically, but please note that filing on paper may result in processing
delays. For more information or any questions pertaining to income, deductions, modifications,
credits, etc., refer to the income tax 112 Book for 2024. Visit Tax.Colorado.gov for additional
information and guidance publications.
Supporting Documents
You must submit all required schedules and supporting certifications to this amended return even if
there is no change from the original return. (For example: Schedule RF, DR 0112CR, DR 0074, etc.)
Failure to include this documentation will result in the disallowance of credits, subtractions or reduced
apportioned income and will result in processing delays.
Lines 49 through 55
Compute the amount you owe to the state on the amended return. Any decrease in the amount of the
overpayment (line 49) or increase in the amount owed (line 50) will indicate that an amount is owed
with the amended return. See Tax Topics: Penalties and Interest for assistance in computing the
amount of interest to enter on line 52. If you have previously been assessed a delinquency penalty
or estimated tax penalty and this amended return causes the amount of penalty to change, enter the
increased penalties on lines 53 and/or 54.
Lines 56 through 60
Compute your refund of credit available on the amended return. Any increase in the amount of the
overpayment (line 56) or decrease in the amount owed (line 57) will indicate that an overpayment is
available with the amended return. The overpayment can be credited to estimated tax (line 59) for the
tax year following the period on the amended return, or can be requested as a refund (line 60).
Statute of Limitations
The statute of limitations for filing a Colorado claim for refund is generally four years from the original
due date of the return or three years from the date of the last payment of tax or the year involved,
whichever is later. In the case of an investment credit or capital loss carryback, the claim must be filed
within four years of the due date of the return for the year during which the credit or loss arose. See
the Corporate Income Tax Guide for more information.
Colorado net operating losses may not be carried back to an earlier year. They may be carried
forward for 15 years from tax years beginning before August 6, 1997, and 20 years from tax years
beginning on or after August 6, 1997.
Protective Claims: If this amended return is being filed as a protective claim that is contingent on
future events and may not be determinable until after the time period for filing a claim for refund
expires, check the protective claim box under reason for filing corrected return.
