See publication FYI Income 51 available at Tax.Colorado.gov
for more information.
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 Tax.Colorado.gov for more information.
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 dened as a large
corporation* under section 6655 of the federal Internal
*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.
