DR 0112 — C Corporation Income Tax Return
Colorado C Corporation Income Tax Return
S Corporations use the DR 0106 instead This filing guide will assist you with completing your Colorado C Corporation Income Tax Return. Please read through this guide before starting your return. Once you have all of the information for your return, file it with a computer, smartphone or tablet using our free and secure system at Colorado.gov/RevenueOnline. You may also file using private e-File software or a paid tax preparer. Filing electronically significantly reduces the chance of errors. If you cannot file electronically, mail your return as instructed. All Colorado forms and publications referenced in this guide are available for download at Tax.Colorado.gov, the official Taxation website. If you are filing on paper, submitting an incomplete return will delay the processing of your return. Please ensure you provide any supporting schedules or forms and documentation as requested in the instructions.
Filing Requirements
Each C corporation doing business in Colorado must file this return. Please see Part 1 of the Corporate Income Tax Guide for guidance in determining whether a C corporation is doing business in Colorado. Organizations that have been granted tax-exempt status by the IRS are generally exempt from Colorado income tax. However, exempt entities that file federal Form 990-T to report unrelated business taxable income from Colorado sources or from business activity in Colorado are subject to Colorado income tax and are required to file the DR 0112. If a tax-exempt entity or local government that is not required to file federal Form 990-T or Colorado form DR 0112 qualifies for a refundable income tax credit, they can file Colorado form DR 0990 to claim the credit. Any insurance company subject to the tax imposed on gross premiums by section 10-3-209, C.R.S., is exempt from Colorado income tax. Due Date You must file this return and pay any amount due by the fifteenth day of the fifth month following the close of the taxable year, which is May 15 for calendar year filers. For filing there is an automatic extension of six months, or until November 15 for calendar year filers, but no extension is available for payment. Use form DR 0158-C to make an extension payment before filing. If the due date or extension date falls on a weekend or legal holiday, filing or payment will be due the next business day.
Estimated Tax
If next year's Colorado tax liability will be greater than $5,000 after subtracting credits, you must make estimated tax payments using the DR 0112EP. For more information, see Part 9 of the Corporate Income Tax Guide. DR 0112 Instructions First, complete the federal income tax return to be filed with the I R S. You will use information from that return to complete the Colorado income tax return. Taxpayer Information Enter the following information in the provided fields. • Fiscal year beginning and ending dates if the tax year is not a calendar year. You must use the same tax year and accounting method for Colorado as for federal tax purposes; • Name of Corporation; • Colorado Account Number (CAN). This 8 digit number is also used on sales tax and wage withholding forms;
• Federal Employer Identification Number (FEIN); • Mailing Address, for the Department to mail letters regarding your income tax account; and • Mark the appropriate box if this is a final return or if you are submitting a statement disclosing a listed or reportable transaction. Section A Mark the appropriate box related to your apportionment method. C corporations that have income from business activity outside of Colorado must apportion and allocate their income to determine the share of their income attributable to Colorado. We recommend that you read the Colorado Corporate Income Tax Guide for more information. Generally, income is apportioned using the receipts factor. • Not Apportioning Income The C corporation has no income from business activity outside of Colorado. Tax will be calculated on 100% of the Colorado taxable income. • Receipts Factor Apportionment All apportionable income must be apportioned pursuant to section 39-22-303.6, C.R.S., using a single factor: receipts. Nonapportionable income must be directly allocated to the appropriate state, unless the taxpayer has checked the applicable box on Schedule RF to elect to treat all income as apportionable income, subject to the receipts factor. The DR 0112RF is required for interstate corporations apportioning and allocating income and can be completed by clicking the appropriate edit button on Revenue Online. Otherwise, submit via the e-Filer Attachment on Revenue Online or send with the paper return. Note that for tax years beginning on or after January 1, 2023, the numerator of the receipts factor for a combined group includes amounts sourced to Colorado regardless of the separate entity to which those factors may be attributed. The numerator is no longer limited to those affiliated corporations doing business in Colorado. • Apportionment Using Special Rule Income from certain industries must be apportioned and allocated in accordance with special rules established by the Department in 1 CCR 201-2. • Exemption Under P.L. 86-272 P.L. 86-272 prohibits a state from imposing a net income tax on the income of a person derived within the state from interstate commerce if the only business activities within the state conducted by or on behalf of the person consist of the solicitation of orders for sales of tangible personal property, provided that the orders are sent outside the state for acceptance or rejection, and, if accepted, are filled by shipment or delivery from a point outside the state. A taxpayer filing a return claiming exemption from Colorado taxation under P.L. 86-272 must complete the return and applicable schedules, but enter $0 tax on line 19. • Other Apportionment Method If the apportionment and allocation provisions of section 39-22-303.6, C.R.S., do not fairly represent the extent of the taxpayer's business activities in Colorado, the taxpayer may request (or the Department might require) an alternative apportionment method. The taxpayer must prove, by a preponderance of the evidence, that the allocation and apportionment provisions of section 39-22-303.6, C.R.S., do not fairly represent the extent of their business activity in Colorado and that the taxpayer's proposed alternative method is reasonable.
Section B Mark the appropriate box to designate a separate, consolidated, combined, or combined/consolidated return. There are four possible filing alternatives for C corporations. We recommend that you read the Corporate Income Tax Guide for additional information. • Separate This designation is for a single corporation, regardless of its membership in an affiliated group. A single corporation cannot use this filing alternative if it elects to be part of a consolidated return or if it is required to be included in a combined filing. • Consolidated This designation is for members of an affiliated group of C corporations, as defined by section 1504 of the Internal Revenue Code. However, only those members doing business in Colorado, as defined in Rule 39-22-301(1), can be included in the consolidated return. This filing alternative is binding for four years and requires consent of the Colorado members of the group. Filing such a return shall be deemed consent. • Combined This designation is for members of an affiliated group of C corporations, as defined by section 39-22-303(12), C.R.S., that meet at least three of the six-part intercompany business relationship tests for this year and the preceding two years. This is a required filing alternative. • Combined/Consolidated This designation is for group of C corporations including some members required to file a combined report and other members not required to be included in the combined report, but electing to be included in a consolidated filing along with those members included in the combined report.

If you assigned the credit to a financing entity or motor vehicle dealer, you cannot claim the credit. If you are a motor vehicle dealer or financing entity with assigned credits, use form DR 0619 and line 43 below instead. Line 32 Business Personal Property Credit If you paid business personal property tax in 2025, calculate and claim this credit as follows. Real property (real estate) is not eligible for this credit. 1. Either find the actual value of your personal property on your assessor statement, or find your assessed value and assessment rate and use this formula: Actual Value = Assessed Value / Assessment Rate The assessment rates for tax year 2024 paid in 2025 are 26.4% (0.264) for agricultural or renewable energy production property or 27.9% (0.279) for all other nonresidential property. For example, an assessed value of $6,975 and an assessment rate of 27.9% would give a calculation of $6,975/0.279 for an actual value of $25,000. If you are claiming credit as a partner in a partnership that paid business personal property tax, you must include in this calculation your distributive share of the total actual value of the personal property on which the partnership paid the tax. 2. Determine your credit amount, which is equal to the tax on up to $18,000 of the actual value of your personal property. a. If the actual value is less than or equal to $18,000, your credit is equal to the tax assessment. b. If the actual value is more than $18,000, use this formula: Credit = (18,000 / Actual Value) * Tax Assessment For example, an actual value of $25,000 and tax of $2,000 would give a calculation of ($18,000 / $25,000) * $2,000 for a credit of $1,440, which is 72% of the tax. If you are claiming credit as a partner in a partnership that paid business personal property tax, you must include in this calculation your distributive share of the business personal property tax paid by the partnership. 3. Enter the credit on your return, and you must submit a copy of the assessor statement with your return. Line 33 Renewable Energy Tax Credit Enter the amount from form DR 1366 line 28. You must submit the DR 1366 and a copy of each certificate with your return. The Department strongly recommends electronic filing for taxpayers with enterprise zone credits.
