2023 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 2023 DR 0112X, Amended Colorado C Corporation
Income Tax Return, is used to correct your 2023 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 2023.
Visit Tax.Colorado.gov for additional information and
guidance publications.

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.

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.

Payment
Taxpayers can now visit Colorado.gov/RevenueOnline to
pay online. Online payments reduce errors and provide a
payment confirmation. Revenue Online also allows users
to submit various forms and to manage their tax account.
Please be advised that a nominal processing fee may apply
to certain payment methods.

Lines 41 through 47 compute the amount you owe to the
state on the amended return. Any decrease in the amount
of the overpayment (line 41) or increase in the amount
owed (line 42) will indicate that an amount is owed with
the amended return. See FYI General 11 for assistance in
computing the amount of interest to enter on line 44. 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 45 and/or 46.

If you file electronically but are unable to remit payment
electronically, please use form DR 0900C to remit your
payment. Make your check payable to the Colorado
Department of Revenue.

Lines 48 through 52 compute your refund of credit
available on the amended return. Any increase in the
amount of the overpayment (line 48) or decrease in the
amount owed (line 49) will indicate that an overpayment
is available with the amended return. The overpayment
can be credited to estimated tax (line 51) for the tax year
following the period on the amended return, or can be
requested as a refund (line 52).
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.

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.

If you are not submitting your return electronically, please
include your payment with this amended return.
