for more information.
General Rule
In most cases, a corporation is required to pay estimated tax if
it can reasonably expect the net tax liability will exceed $5,000
for 2021. For taxpayers with a short taxable year, please see
FYI Income 51 or refer to Department regulation 39-22-606
available at for more information.
Required Payments
The required annual amount to be paid is the smaller of:
70% of the actual net Colorado tax liability; or
100% of the preceding year’s net Colorado tax liability.
This rule only applies if the preceding year was a
12-month tax year, the corporation led a Colorado
return, and the corporation is not dened as a large
corporation* under section 6655 of the federal Internal
Revenue Code.
*Any large corporation may base their rst quarter estimated
tax payment on 25% of the tax liability from the previous year.
However, the remaining payments must be based on the actual
tax liability for the current year. If, after calculating the tax liability
for the current year, it is determined that the rst quarter was
underestimated the shortage shall be calculated into and paid
with the second quarter.
Calculating the Payment
Use the provided worksheet to calculate the amount of estimated
tax owed. Payments and forms should be submitted using the
same method (separate, consolidated, combined) and using
the same account number as will be used on the C Corporation
Income Tax Return (DR 0112). If, for any reason, the account
numbers are inconsistent, the department must be notied in
writing prior to ling DR 0112.
Mail this notication to:
Colorado Department of Revenue

Remit payments on or before the due date table provided on
the next page (adjust for scal year taxpayers). It is strongly
recommended that payments be remitted electronically to
avoid processing delays. This form can be copied and used for
each of the four quarterly payments, if an electronic payment
cannot be made for any reason.
Failure to timely remit estimated tax as necessary will result
in an estimated tax penalty. Penalty will be calculated for
each missed payment, late payment, or underpayment. For
calculation specics, or to remit this penalty before being billed,
see form DR 0205, Underpayment of Corporate Estimated Tax.
Go Green with Revenue Online allows taxpayers to le
taxes, make payments and monitor their accounts. The
DR 0112EP is not required to be sent if electronic payment
is made through this site. Please be advised that a nominal
processing fee may apply to online payments.
Pay by Electronic Funds Transfer (EFT)
EFT payments can be made safely, for free, and can
be scheduled up to 12 months ahead of time to avoid
forgetting to make a quarterly payment. This requires
pre-registration before payments can be made.
Visit for registration information.
