Legal representatives and surviving spouses may file a return on behalf of a deceased person whose date of death was during the tax year. Surviving spouses may complete the return as usual and indicate the deceased status on the return. They can file the return and submit a copy of the death certificate through Revenue Online. Legal representatives may file the return and submit a copy of the death certificate through Revenue Online, but they must complete the Third Party Designee portion of the return. Either a surviving spouse or legal representative can avoid problems when filing on paper by marking the box next to the name of the deceased person, writing “DECEASED” in large letters in the white space above the tax year of the return, writing “FILING AS SURVIVING SPOUSE” or “FILING AS LEGAL REPRESENTATIVE” after their signature, and attaching the DR 0102 and a copy of the death certificate to the return.
To claim a refund on behalf of a deceased person, complete the DR 0102and submit it, as well as a copy of the death certificate, when filing the return.
If you can’t file your Colorado income tax return by the deadline you may take advantage of the state’s automatic six-month extension of time to file. There is no form, paper or electronic, to fill out to notify the Department of Revenue that you are taking the extension. There’s no extension for tax due.
The extension applies to filing Colorado income tax information, either on paper or electronically, not to any state income tax you may owe. If you expect to get a refund this year but do not make the filing deadline, you can still file your state income tax on or before October 16.
But, if you owe state income tax, 90 percent of the tax liability must be paid on or before the April 18 to avoid penalties. Any remaining balance due would be subject to interest only.
Note: If you were living or traveling abroad on April 18, the deadline for filing your return and paying any taxes owed is June 15. However, if you need more time to file you will automatically have until October 16, to file your state tax return. This extension of time to file only applies to the actual return not to funds owed.
If you owe tax, you must either pay through Revenue Online or submit your payment with the appropriate year and tax type Payment Voucher as follows:

A Colorado resident is a person who has made a home in Colorado, or a person whose intention is to be a Colorado resident.

A Colorado resident reporting U.S. federal taxable income must continue to file Colorado returns as a full-year resident no matter how long he or she is out of the country. Most such individuals are working on a temporary assignment, and plan on returning to Colorado. However, all foreign income that is exempt for federal purposes is also exempt for Colorado purposes.
Individuals who abandon their Colorado domicile and become permanent residents of a foreign country no longer have to file Colorado returns. However, they would have to file a Colorado tax return as a nonresident if they had Colorado-source income (e.g., rental income). Such individuals bear the burden of proving their abandonment of Colorado residency. Continued Colorado residency will be presumed if the individual has not severed all Colorado connections; for example, if the individual still carries a Colorado driver license, votes in Colorado by absentee ballot, and/or still owns a home in Colorado, or returns to Colorado.
If you were living or traveling abroad on April 15, the deadline for filing your return and paying any taxes owed is June 15. However, if you need more time to file you will automatically have until October 15, to file your state tax return. This extension of time to file only applies to the actual return -- not money owed. If tax is owed, you can avoid any late payment penalties if you pay at least 90 percent of your tax liability by June 15.
Every person in the military service must have a home state. A service member remains a resident of the state in which he/she resided at the time he/she entered the service unless he/she declares residency in another state. The service member would declare residency in another state by changing his/her residency with the Consolidated Base Personnel Office or Military Pay Office. Only the service member's home state may tax his/her military income. Find out more about special filing information for military service members at Military Service Members -- Quick Answers.

This is NOT claimed on your Colorado income tax return because the figure has already been taken out of your federal taxable income when you start to complete your Colorado return. The ownership tax is listed on the back of the car registration receipt with the address listed.
