4 How To Use This Filing Guide This filing guide will assist you with completing your Colorado Income Tax Return. Please read through this guide before starting your return. Once you have all of the information for your return, file it and pay any amount due on 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 with a paid tax preparer. Filing electronically significantly reduces the chance of errors. If you cannot file electronically, mail your return as instructed. Please ensure that you submit any supporting forms, schedules, and documentation as requested in the instructions. All Colorado income tax forms and guidance publications are available at our official website, Tax.Colorado.gov. The following symbols appear throughout this guide and point out important information, reminders and changes to tax rules. This points out a topic that is the source of common filing errors. Filing your return on Revenue Online will reduce the risk of errors; however, it is important to understand the information on your return. Errors cause processing delays and erroneous bills. This points out subtractions and tax credits that require you to provide supporting documentation. Not submitting the required documentation will cause processing delays or denial of the subtractions and credits. These documents can be scanned and attached to your electronic filing through Revenue Online or most tax software, mailed with the DR 1778 or included with your paper return. In-depth tax information is available in our easy to understand guidance publications, which include examples and worksheets. This symbol lets you know when such a publication is available for a subject. All guidance publications are available at Tax.Colorado.gov/guidance-publications. Filing Information Who Must File This Tax Return Generally, you must file a Colorado income tax return if you: • Are required to file a federal income tax return with the IRS for the tax year, or • Have a Colorado income tax liability for the tax year, And you are: • A full-year Colorado resident (you must file DR 0104 or DR 0104EZ), or • A part-year Colorado resident who received taxable income while residing here (you must file DR 0104 with DR 0104PN), or • Not a Colorado resident, but received income from Colorado sources (you must file DR 0104 with DR 0104PN). Colorado residents must file a Colorado return if they are required to file an income tax return with the IRS, even if they do not have a Colorado tax liability. Otherwise, the Department may file a return on your behalf and our return might not consider your unique tax situation. Also, the only way to determine if you are entitled to a refund is to file a return. Due Date Your Colorado income tax return and payment for any tax owed are due April 15. Revenue Online will accept returns as timely filed until midnight. Mailed returns and payments must be postmarked by April 15. An automatic extension to file is granted until October 15, but there is no extension to pay. If you need to make a payment before filing, see form DR 0158 in this book. If a due date falls on a weekend or legal holiday, the return or payment will be due the next business day.

5 Deceased Persons A surviving spouse or personal representative may file a return for a deceased taxpayer. A personal representative can be an executor, administrator, or anyone who is in charge of the deceased taxpayer’s property. If a deceased taxpayer had tax withheld, a return must be filed to get a refund. Enter the Return • Use the deceased taxpayer’s federal filing status for the tax year. For a joint return, also enter the surviving spouse’s information. • Mark the Deceased checkbox after the deceased taxpayer’s name. • Enter the address where you want to receive any correspondence from the Department regarding the return. • Claim all credits, subtractions, and deductions to which the deceased taxpayer is entitled. Sign the Return • A surviving spouse must sign on the appropriate line and write “Filing as Surviving Spouse” after the signature. • A legal representative must complete the Third Party Designee section, sign in place of the deceased, and write “Filing as Legal Representative” after the signature. You must submit with the return: • A copy of the death certificate; and • If applicable, a Claim for Refund on Behalf of a Deceased Taxpayer (DR 0102). Filing Status You must file using the same filing status on both your federal and Colorado income tax returns. Any two individuals who legally file a joint federal income tax return must also file a joint Colorado income tax return. Individuals filing jointly must enter the taxpayer and spouse in the same order on both the federal and Colorado returns. For married filing separately, do not list your spouse’s information on your return. Claiming Credits from a Partnership or S Corporation To claim a tax credit as a partner or shareholder, obtain Colorado form DR 0106K from the partnership or S corporation. Enter the credit from DR 0106K on your return, and submit a copy of DR 0106K with your return. The partnership or S corporation must also file DR 0106K with their return, and the Department will verify your credit claim by reviewing the partnership or S corporation’s return. Instructions for the DR 0104 First, complete the federal income tax return you will file with the IRS. You will use information from that return on your Colorado return. Colorado income tax is based on your federal taxable income, which has already considered your deductions. Residency Status Mark the appropriate box for your residency status. If you are filing a joint return, and one person is a full-year Colorado resident and the other is either a part-year resident or a nonresident, mark the Part-Year Resident/Nonresident box. Part-Year Colorado Residents and Nonresidents Tax is prorated so that it is calculated only on income received in Colorado or from sources within Colorado. We recommend you review Income Tax Topics: Part-Year Residents & Nonresidents if this applies to you. You will calculate your prorated tax by completing the DR 0104PN. You must submit the DR 0104PN along with the DR 0104.

6 Persons Traveling or Residing Abroad If you are traveling or residing outside the United States on April 15, the deadline for filing your return is June 15. If you need additional time to file your return, you will automatically have until October 15 to file. Interest is due on any tax paid after April 15. To avoid any late payment penalties, you must pay 90% of your tax liability by April 15, file your return by October 15 and pay any remaining tax due at the time of filing. If the due date falls on a weekend or legal holiday, return will be due the next business day. When filing your return, mark the “Abroad on Due Date” box on Revenue Online or the paper return. Active Duty Military Under federal law, a military servicemember’s state of legal residence does not change solely as the result of the servicemember’s assignment for service in another state. Consequently, a Colorado resident who enters into military service will remain a Colorado resident unless they officially change their state of legal residence as described in DD Form 2058. In general, military servicemembers who are Colorado residents are subject to the same income tax filing requirements as other Colorado residents, even if they are serving in another state. These requirements are described on the preceding page, under the heading “Who Must File This Tax Return.” However, a military servicemember who spends at least 305 days of the tax year stationed outside of the United States on active military duty may elect to be treated as a nonresident. The servicemember may make this election by filing a return and checking the applicable box on Form 104PN. Military servicemembers who are stationed in Colorado, but are not Colorado residents, are not required to pay Colorado tax on their military income. However, any other Colorado source income of a nonresident servicemember is subject to Colorado taxation. Please see Tax.Colorado.gov/military-servicemembers for additional information. These rules also apply generally to a servicemember’s spouse who is residing with the servicemember either inside or outside of Colorado in compliance with the servicemember’s military orders. If a servicemember and their spouse are nonresidents stationed in Colorado, any wages earned by the spouse for work performed in Colorado are not subject to Colorado taxation. The military spouse must complete a DR 1059, provide a copy to their employer when hired for employment, and submit a copy to the Department, along with a copy of their military ID card, with their Colorado return each year. The DR 1059 may be filed through Revenue Online, with DR 1778, or included with a DR 0104 filed by paper. Taxpayer and Spouse Information Enter the following information in the provided fields. If filing jointly, enter your spouse’s information. Otherwise, leave the spouse’s information blank. • First name, last name, and date of birth. • Social Security Number (S S N) or Individual Taxpayer Identification Number (I T I N). • The following information from your current driver license or state identification card: The state of issuance, the last four characters of the ID number, and the date of issuance. • Your mailing address and phone number. The Department will use the address provided to mail letters regarding your income tax account. Dependents Enter the name, Social Security Number (S S N) or Individual Taxpayer Identification Number (I T I N), and year of birth for all of your dependents.

7 Check the “Deceased” box for a child who was born and died in this tax year and was not assigned an S S N or I T I N. Unless this box is checked, each dependent listed must have an S S N or I T I N issued by the IRS on or before the due date for this return (including extensions). If you check the “Deceased” box, you must submit a copy of the child’s birth certificate, death certificate, or hospital records showing a live birth with your return. If you have more than five dependents, you must file your return electronically. You can use our free and secure system at Colorado.gov/RevenueOnline, private e-File software, or a paid tax preparer. Filing electronically significantly reduces the chance of errors. Who qualifies as your dependent? For Colorado income tax purposes, your dependents will generally be the same as the dependents you claimed on IRS form 1040. The instructions for IRS form 1040 and IRS Publication 501, can help you determine whether a person is your dependent. There may be additional or different requirements for you to claim a particular Colorado tax credit for a dependent. However, you should list all of your dependents in this section even if you cannot claim them for any Colorado tax credits. Also include in this section any child who is not your dependent for federal income tax purposes but for whom the following conditions are met: • You are the custodial parent for the child. • You signed IRS Form 8332 allowing the noncustodial parent to claim the child as a dependent. • The child is your qualifying child for the purpose of the federal Earned Income Tax Credit and the Colorado Earned Income Tax Credit. • You are claiming the Colorado Earned Income Tax Credit on your return. Please see IRS Form 8332, IRS Publication 501, and IRS Publication 596 for additional information. Does the dependent qualify for the Colorado child tax credit? If a dependent meets the following requirements, check the Child Tax Credit box. In general, the dependent must be a qualifying child for federal income tax purposes in order to check the box. • The dependent must be your son, daughter, stepchild, foster child, brother, sister, half brother, half sister, stepbrother, or stepsister, or a descendant of any of them (for example, your grandchild, niece, or nephew) (see Relationship Test in the Qualifying Child section of IRS Publication 501). • The dependent must be under age 17 at the end of the tax year. • The dependent must have lived with you for more than half of the tax year (see Residency Test in the Qualifying Child section of IRS Publication 501). • The dependent must not have provided more than half of their own support for the tax year (see Support Test in the Qualifying Child section of IRS Publication 501). • The dependent must not be filing a joint return for the tax year (unless that joint return is filed only to claim a refund of withheld income tax or estimated tax paid) (see Joint Return Test in the Qualifying Child section of IRS Publication 501). If you check the Child Tax Credit box, go to form DR 0104CN to determine whether you qualify for the Colorado child tax credit. If you are the custodial parent of a child you cannot claim as a dependent for federal income tax purposes, and for whom you cannot claim a Federal Child Tax Credit, you cannot claim a Colorado Child Tax Credit for that child.

8 Colorado Health Coverage Easy Enrollment Colorado taxpayers can now share certain information from their state tax return with the Colorado Health Benefit Exchange (Connect for Health Colorado) and the Colorado Department of Health Care Policy & Financing to find out if they qualify for free or reduced-cost health coverage (Colorado Law: 39-21-113(25) C.R.S). To share your information, complete form DR 0104EE and submit it with your return. Please see form DR 0104EE and its instructions for additional information. Line 1 Federal Taxable Income Enter your federal taxable income from your federal income tax form 1040, 1040 SR, or 1040 SP, line 15. If your federal taxable income is a negative amount, enter the amount as negative on your Colorado return. On a paper return, put the negative amount in parentheses, for example ($1,234). Do not enter your total income or wages on this line because it will make your tax too high. The Department will compare the amount you list here to the return you file with the IRS, so be careful to complete this correctly. Additions Line 2 State Income Tax Addback You must enter on line 2 any state income tax deducted on Schedule A of your federal return, subject to certain limitations. If you are a partner or shareholder in a partnership or S corporation that claimed a federal deduction for state income taxes, you must also include on line 2 your distributive or pro rata share of any state income tax deducted by the partnership or S corporation. Your distributive or pro rata share of state income taxes deducted by a partnership or S corporation should appear on line 9 of the Colorado form DR 0106K that you received from the partnership or S corporation. Do not enter on line 2 any general sales taxes or local income taxes that you deducted on Schedule A of your federal return. For additional information, please see the Department publication Income Tax Topics: State Income Tax Addback. Line 3 Qualified Business Income Deduction Addback There are two cases where you may be required to add back the amount of a deduction for qualified business income under section 199A of the Internal Revenue Code. If you claimed a deduction for qualified business income under section 199A of the Internal Revenue Code (IRS form 1040, line 13a), and your adjusted gross income is greater than $500,000 ($1,000,000 if filing jointly) (IRS form 1040, line 11a), you are required to add to federal taxable income an amount equal to that deduction. You must add back the entire deduction regardless of the extent to which your adjusted gross income exceeds the threshold. This addback does not apply to a taxpayer who is required to file a federal Schedule F, Profit or Loss From Farming, with their federal income tax return. Alternatively, if you are a partner in a partnership that made a SALT Parity Election or a shareholder in an S corporation that made a SALT Parity Election, you are required to add to federal taxable income an amount equal to your qualified business income under section 199A of the Internal Revenue Code. You must add back the entire deduction regardless of your adjusted gross income. This addback is not limited to the deduction taken with respect to the electing partnership or S corporation. The partnership or S corporation will indicate that it made the election by marking the SALT Parity Election box on the Colorado K-1 (DR 0106K) issued to you. Line 4 Standard or Itemized Federal Deduction Addback Taxpayers who have federal adjusted gross income exceeding $300,000 in tax year 2025 may be required to add back itemized or standard deductions over a certain amount in this line.

9 If your federal return filing status was single, married filing separately or head of household AND the following conditions apply: Your federal adjusted gross income as reported on line 11a of IRS Form 1040 exceeds $300,000 and Your itemized or standard deductions on line 12e of IRS Form 1040 exceed $12,000. Then the required addback amount is calculated by subtracting $12,000 from the amount on line 12e of IRS Form 1040. This amount should be reduced by any state income tax deduction from Schedule A of your federal return that is already added back on line 2 of Colorado Individual Income Tax Return DR 0104. The required addback is not reduced by any amount of state income tax addback on line 2 of your Colorado form 104 attributable to your share of state income tax deducted by a partnership or S corporation. If the filing status for your federal return was married filing jointly AND the following conditions apply: Your federal adjusted gross income as reported on line 11a of IRS Form 1040 exceeds $300,000 and Your itemized or standard deductions on line 12e of IRS Form 1040 exceed $16,000. Then the required addback amount is calculated by subtracting $16,000 from line 12e of IRS Form 1040. This amount should also be reduced by any state income tax deduction from Schedule A of your federal return that is already added back on line 2 of Colorado Individual Income Tax Return DR 0104. The required addback is not reduced by any amount of state income tax addback on line 2 of your Colorado form 104 attributable to your share of state income tax deducted by a partnership or S corporation. Line 5 Business Meals Deduction Addback Enter on line 5 the full amount of any federal deduction claimed for business meals on line 24b of Schedule C of Form 1040. Also include on line 5 any business meals addition from line 10 in Column A on any Colorado K-1 (DR 0106K) issued to you by a partnership or S corporation. Line 6 Non-qualifying Distribution addback (CollegeInvest Tuition Savings) An account holder must make an addition on their Colorado return for any distribution, refund, or withdrawal from a qualified state tuition program for any reason other than one of the following qualifying reasons: • To pay qualified higher education expenses (discussed in Department publication Income Tax Topics: CollegeInvest Contribution Subtraction); • As a result of a beneficiary’s death or disability; • As a result of receiving a scholarship during the tax year in an amount equal to or greater than the distribution, refunds, or withdrawals made; or • As a result of a change in the designated beneficiary for the account, as described in Chapter 7 of IRS Publication 970. Line 7 Non-qualifying Distribution addback (Colorado ABLE) An account holder must make an addition on their Colorado return for any distribution, refund, or withdrawal from a qualified ABLE program if used for a purpose other than one of the following qualifying reasons: • To pay qualified disability expenses (discussed in Department publication Income Tax Topics: ABLE Contribution Subtraction); • As a result of a beneficiary’s death or disability; • As a result of a change in the designated beneficiary for the account, as described in the “ABLE Account” section of IRS Publication 907.

Correcting Errors or Changing a Return You may amend your return using our free and secure system at Colorado.gov/RevenueOnline, even if the original return was filed on paper. Revenue Online has all the information from your original return, so you will not need to re-enter everything. • If you cannot amend online, you can mail form DR 0104X. Make sure you use the appropriate form version for the year you are amending. • You must amend your Colorado return to report any change to an item or amount determined under the Internal Revenue Code that is used to compute Colorado income tax.

An amended Colorado return is due within 180 days after a federal adjustment is finalized. See Part 8 of the Colorado Individual Income Tax Guide for more information. It is very important that you submit all schedules and supporting documentation for any changes with your amended return. You must submit all schedules, even if you are not changing those values. Estimated Tax Requirements If you expect next year’s Colorado tax liability to be greater than $1,000 after subtracting credits, you should make estimated tax payments using the DR 0104EP. We recommend that you read the Individual Income Tax Guide for additional information. Filing Errors and Incomplete Information It is important to read all the information available for your specific tax situation and to submit all required documentation with your return. Failure to do so may result in delayed processing of your return and refund, if any. We recommend that you file using Revenue Online to avoid common mathematical errors.

If you are filing a joint return, enter on line 3 only the primary taxpayer’s social security benefits that are eligible for the subtraction and enter on line 5 any of the secondary taxpayer’s social security benefits that are eligible for the subtraction. If you were 65 years of age or older on December 31, 2025, you may claim the subtraction for the entire amount of the social security benefits you received that were included in your federal taxable income. If on December 31, 2025, you were at least 55 years old but not yet 65 years old, the subtraction you can claim depends in part on your federal adjusted gross income on line 34 of your form DR 0104. You may claim the subtraction for the entire amount of the social security benefits you received that were included in your federal taxable income if either: • Your filing status was single and your federal adjusted gross income did not exceed $75,000; or • Your filing status was married filing jointly and your federal adjusted gross income did not exceed $95,000.

Line 7 Business Personal Property Credit for Individual Business Owners 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 divided by 0.279 for an actual value of $25,000. If you are claiming credit as partner or shareholder in a partnership or S corporation that paid business personal property tax, you must include in this calculation your distributive or pro rata share of the total actual value of the personal property on which the partnership or S corporation 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.

26 (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 the following calculation: Divide $18,000 by $25,000, then multiply by $2,000, resulting in a credit of $1,440, which is 72% of the tax. If you are claiming credit as partner or shareholder in a partnership or S corporation that paid business personal property tax, you must include in this calculation your distributive or pro rata share of the business personal property tax paid by the partnership or S corporation. 3. Enter the credit on your return, and you must submit a copy of the assessor statement with your return.

The care must be for one or more qualifying persons. 2. You (and your spouse if filing jointly) must have earned income during the year. 3.

If you make payments to your child, he or she cannot be your dependent and must be age 19 or older by the end of the year. You cannot make payments to: a. Your spouse, or b.
