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 publication FYI Income 6 if this applies to you. You will calculate your prorated tax by completing the DR 0104PN. You must submit the DR 0104PN with your return.
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, 2020. If you need additional time to file your return, you will automatically have until October 15, 2020, to file. Interest is
due on any tax paid after April 15, 2020. To avoid any late
payment penalties, you must pay 90% of your tax liability by June 15, 2020, file your return by October 15, 2020 and pay any remaining tax due at the time of filing. 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 service-
member’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, any 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 “Military Service Members — Special Filing Information” webpage on our website for additional information.
The residency rules described above for military servicemembers also apply generally to a
servicemember’s spouse if the spouse 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, when they file their Colorado return each year. The DR 1059 may be filed with the Department through Revenue Online, with DR 1778,
or as an attachment to a DR 0104 filed by paper.
Name and Address
Provide your name, mailing address, date of birth, Social
Security number, as well as the state of issue, last four digits, and the date of issuance of your state issued ID card in the provided spaces. If filing Married Filing Joint, provide the spouse’s information where prompted. Provide the spouse’s information ONLY if filing a joint return. Otherwise leave blank. All Departmental correspondence will be mailed to
the mailing address provided. We recommend you read publication FYI General 2 for the Privacy Act Notice.
Line 1 Federal Taxable Income
Refer to your federal income tax return to complete this line:
• Form 1040 line 11b
If your federal taxable income is a negative amount, be sure to enter the amount as such on your Colorado return. If submitting 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 very careful
to complete this correctly.
Additions
Line 2 State Addback
Refer to your federal income tax return to complete this line.
Enter $0 if you filed Form 1040 or 1040SR but did not itemize
your deductions on Schedule A.
Taxpayers who deduct general sales taxes on Schedule A
line 5a, Form 1040 or 1040SR, are not required to calculate this addback. If you deducted state income tax on Schedule
A line 5a, complete the worksheet below to calculate the Income Tax Deduction.
