Colorado Tax Form 104 - Individual Income Tax Return Instructions
Filing Information
Who must file a return
You must file a 2008 Colorado income tax return if during 2008 you were:
- A full-year resident of Colorado, or
- A part-year resident of Colorado with taxable income during that part of the year you were a resident, or
- A nonresident of Colorado with Colorado source income;
AND
- You are required to file a 2008 federal income tax return,
or - You have a 2008 Colorado income tax liability.
TIP: Even if no tax is due, you may wish to file a return to get a refund of wage withholding.
Part-year residents and nonresidents
Part-year and nonresidents of Colorado should refer to Form 104PN on page 17 of this booklet. See FYI 6.
Active members of the armed forces
If you were a Colorado resident when you joined the armed forces, you remain a Colorado resident unless you change it with the military. This means that you must file as a Colorado resident even if you are stationed outside the state. If you were stationed outside of the United States for at least 305 days during 2008 you may file as a nonresident if you wish. See FYI 21. If you are in Colorado on military orders but are not a Colorado resident, Colorado does not tax your military pay. However, you must file a Colorado return for any other earned income from Colorado sources.
Filing on behalf of a deceased taxpayer
If you are a surviving spouse or legal representative of someone who died during 2008, you may file a return on the deceased’s behalf. Write “deceased” in large letters across the top of the return, check the box after the deceased person’s name and write the date of death next to the deceased person’s name. Additionally, you must sign the return and write “filing as surviving spouse” or “filing as legal representative” by your signature. Any person other than the surviving spouse who files a return and requests a refund on behalf of a deceased person must file Form 102 and a copy of the death certificate with the return.
Filing status
Your Colorado filing status will always be the same as your federal filing status. For example, if you file a joint federal return, you must file a joint Colorado return even if one spouse is not a Colorado resident.
Spouse’s intercepted refund
If you file a joint return and one spouse owes money to a state agency that is going to intercept your refund, the injured spouse (the person not in debt) may claim his/her portion of the refund.
The portion is determined by dividing the injured spouse’s gross income by the joint gross income and multiplying the resulting percentage by the income tax refund. A written claim, along with a copy of your federal return or federal form 8379 and copies of all W-2s, must be filed to receive the refund. Do not send this claim with your return. Mail it in a separate envelope to the attention of the “Injured Spouse Desk.”
When to file
Your Colorado income tax filing and tax payment are due by April 15, 2009. You may file your return electronically anytime up to midnight April 15th. If you choose to complete a paper return, mail your return and, if applicable, your tax payment to:
Colorado Department of Revenue
Denver, CO 80261-0005
The envelope must be postmarked by April 15, 2009. If you cannot complete your return by the April 15 deadline, you may be able to file under extension. See page 11 of this booklet for details.

Line by Line Instructions
The following instructions apply whether you file electronically or on paper. Electronic filers should use the forms in this guide as worksheets prior to entering the information in NetFile, TeleFile or other tax software.
HOW DOES FORM 104 WORK?
You must complete your federal income tax filing/return before you can start your Colorado return because line 1 of the Colorado form is your federal taxable income, which has your deductions and exemptions already subtracted out. You then may have to add or subtract certain types of income on lines 2 through 12. This gives you the Colorado taxable income you take to the tax table to determine the Colorado tax you owe. You will then subtract any credits you have on lines 19 through 29. These credits include items from Form 104CR, and any tax you have prepaid through withholding from your wages or estimated tax payments. If these credits are more than the tax due, you get a refund. If these credits are less than the tax due, you must pay the difference.
RESIDENCY STATUS
Check the proper box at the top of Form 104 to indicate whether you are filing as a full-year resident, a part-year resident or as a nonresident. If one spouse is a full-year resident and the other is a part-year resident or a nonresident, check only the part-year resident/nonresident box.
NAME AND ADDRESS
Print your name, address, and social security number in the spaces provided. If you are filing a joint federal return, you must file a joint Colorado return and include your spouse's name and social security number. For Privacy Act Notice, see FYIGeneral 2.
DO NOT enter a name or social security number on the "spouse" line if you are not filing a joint return. If you are entering an address for a foreign country, place any postal code at the end of the address line and enter Xs in the ZIP code box.
INCOME
Line 1 FEDERAL TAXABLE INCOME
Enter your federal taxable income from:
- federal Form 1040, line 43
- federal Form 1040A, line 27 or,
- federal Form 1040 EZ, line 6.
If your federal deductions exceed your federal adjusted gross income, enter the excess as a negative amount (in brackets) on line 1. The amount you enter on line 1 will be compared to the amount you report on your federal income tax return.
Your federal taxable income is your total income minus your federal exemptions and deductions. Do not put your total income or wages on this line because it will result in your tax being computed too high. Do not deduct your personal exemptions, standard deduction, or itemized deductions on your Colorado income tax return because they have already been allowed on line 1.
ADDITIONS TO INCOME
Line 2 STATE INCOME TAX DEDUCTION ADDBACK
If you filed federal form 1040A or 1040EZ for 2008, enter $0 on line 2.
If you did not itemize deductions on your 2008 federal income tax return, enter $0 on line 2.
If you did itemize deductions on your 2008 federal income tax return but deducted general sales taxes on line 5, schedule A, Form 1040, enter $0 on line 2.
If you did itemize deductions on your 2008 federal income tax return and deducted income taxes on line 5, Schedule A, Form 1040, you must add back on your Colorado return any state income tax included in your federal itemized deductions. If your federal itemized deductions exceed the standard deduction you could have claimed by an amount that is less than the state tax deduction, you add back only the difference between the itemized and standard deduction amounts.
| Complete the following schedule to determine your state income tax deduction addback | |
| (a) State income tax deduction from line 5, Schedule A, federal Form 1040 | $ |
| (b) Total itemized deductions from line 29, Schedule A, federal Form 1040 | $ |
| (c) The amount of federal standard deduction you could have claimed (See line 40, federal Form 1040 for allowable federal standard deductions). | $ |
| (d) Line (b) minus line (c), but not less than $0 | $ |
Enter the smaller of line (a) or line (d) on Form 104, line 2. For most Colorado taxpayers who itemize deductions, the state income tax deduction addback will be the amount from line 5, Schedule A, Form 1040. See FYI 4.
Individuals with high incomes who are not allowed to claim all of their federal itemized deductions can refer to publication FYI 3.
Married persons filing separate returns should refer to 4 to determine the amounts to enter in the worksheet.
Line 3 OTHER ADDITIONS TO FEDERAL TAXABLE INCOME
Enter on line 3:
- The amount of interest you earned during 2008 from bonds issued by any state or any state political subdivision other than bonds issued on or after May 1, 1980 by the State of Colorado or any of its political subdivisions. The amount you report on line 3 should be the gross amount of state and local bond interest minus amortization of bond premium and expenses required to be allocated to such interest income under provisions of the Internal Revenue Code. See FYI 52.
- The amount of lump-sum distribution from a pension or profit sharing plan you reported on federal Form 4972. Because this income is not included in federal taxable income on line 1, these distributions must be added on line 3. The distribution should be reduced by any estate tax allocated to the distribution on Form 4972.Distributions included on this line are subject to 10year averaging on the federal return. If the lump-sum distribution is not subject to 10-year averaging and is included in federal taxable income on line 1, then it should not be reported again on line 3. Amounts entered on this line may be eligible for the pension exclusion on lines 7 or 8.
- The smaller of the amount from line 14, federal Form 8814 or $900 if you are electing to report your child's income for federal tax purposes. • Any federal charitable contribution deduction on which you also claimed a Colorado gross conservation easement credit. See FYI 39.
- Any fiduciary adjustment or partnership modification that increases your federal taxable income.
SUBTRACTIONS FROM INCOME
Line 5 STATE INCOME TAX REFUND SUBTRACTION
Enter any state income tax refund you reported as income on line 10 of your federal Form 1040. Enter $0 if you filed federal Form 1040EZ or 1040A.
Line 6 UNITED STATES GOVERNMENT INTEREST
Enter any interest you earned during 2008 from U.S. government bonds, treasury bills and other obligations of the United States or its territories, possessions and agencies that was included in federal taxable income. Do not enter interest earned from Federal National Mortgage Association and Government National Mortgage Association (Fannie Mae and Ginnie Mae). Dividends received from mutual funds may not be 100% exempt. See FYI 20.
Line 7 PENSION AND ANNUITY SUBTRACTION
If you received pension or annuity income and
- the income is included in your federal taxable income, or
- a lump-sum distribution is reported on line 3, above,
Then
- if, as of December 31, 2008, you were 65 or older, enter the smaller of the income or $24,000;
- if, as of December 31, 2008, you were at least 55 but not yet 65, enter the smaller of the income or $20,000;
- if, as of December 31, 2008, you were under 55, you do not qualify for the pension subtraction unless you are receiving the income as a secondary beneficiary (e.g., a widow, dependent child, etc.) due to the death of the person who earned the pension, in which case you enter the smaller of the income or $20,000.
For information and exceptions, see 18 and 25.
To qualify for the subtraction, a payment must be:
- pension or annuity income that is not considered a premature distribution, and
- reported on the federal return as taxable IRA distributions, pensions and annuities, or social security benefits (lines 15b, 16b, or 20b of federal Form 1040; lines 1lb, 12b, or 14b of federal Form 1040A), or reported as a lump sum distribution on line 3 of Colorado Form 104.
Example: Joseph (age 66) and Catherine (age 63) receive social security benefits in 2008 of $20,000, $6,000 of which was taxable on their joint federal return. Joseph received $12,000 of the benefits while Catherine received $8,000. Catherine also earned a private pension of $22,000, $18,000 of which was taxable on the federal return.
- Joseph's pension subtraction is computed by taking his share of the total social security benefits paid times the taxable benefits (60% of $6,000), which is $3,600.
- Catherine's pension subtraction is computed by taking her share of the social security benefits times the taxable benefits (40% of $6,000) and adding her taxable private pension ($18,000), which is $20,400. Because Catherine is under age 65 her subtraction is limited to $20,000.
Line 8 PENSION AND ANNUITY SUBTRACTION SPOUSE
If you are filing a joint return, enter the spouse's pension or annuity subtraction, if any, on line 8. See line 7 instructions for a definition of excludible pension/annuity income. The spouse must also qualify by age to claim the pension/annuity subtraction. Each spouse's subtraction is computed separately and no part of one spouse's $20,000 or $24,000 subtraction may be claimed by the other. See FYI 25.
Line 9 COLORADO SOURCE CAPITAL GAIN
You can subtract capital gain income IF:
- Federal taxable income-the income is included in your federal taxable income;
AND
- Colorado sources–the income is earned from:
- the sale of real or tangible personal property located in Colorado at the time of the transaction, or
- the sale of stock or ownership interest in a "Colorado company;"
AND

Payments or contributions you made during 2008 to a qualified state tuition program administered by CollegeInvest can be deducted, but only to the extent they are included in federal taxable income. See FYI 44.
Line 11 QUALIFYING CHARITABLE CONTRIBUTION
Taxpayers who claim the federal standard deduction instead of itemizing their deductions on the federal return may be able to subtract a portion of their charitable contributions made during the year. Enter only the amount in excess of $500 that you could have deducted on federal Schedule A under the "Gifts to Charity" section had you itemized your federal deductions. See FYI 48.
| Complete the following schedule to determine your qualifying charitable contribution subtraction: | |
| (a) Did you itemize your deductions on the federal Schedule A? | Yes No |
| (b) Did you deduct your charitable contributions on the federal return as a business or other deduction? | Yes No |
| If you answered yes on lines (a) or (b), enter $0 on line 11, you do not qualify for this subtraction. If you answered no on lines (a) and (b), continue with line (c). | |
| (c) Enter the amount you could have deducted for charitable contributions on lines 16 and 17 of federal Schedule A. | $ |
| (d) Nondeductible contributions | $ 500 |
| (e) Qualifying charitable contribution subtraction, line (c) minus line (d), but not less than $0 | $ |
| $ Enter the amount from line (e) on Form 104, line 11. | |
