• A resident estate or trust, or
• A nonresident estate or trust with income from Colorado sources;
That also:
• Is required to file a federal income tax return for the tax year, including an information return such
as Form 5227 or 1041A, or
• Has a Colorado tax liability.
Resident Estate or Trust
A resident estate is an estate of a deceased person which is administered in Colorado in any manner
other than by an ancillary proceeding. A resident trust is any trust which is administered in Colorado.
Nonresident Estate or Trust
A nonresident estate or trust is an estate or trust that is not a resident estate or trust. Use Schedule
E to apportion the Colorado tax in the ratio of the Colorado taxable income to the modified federal
taxable income.
Deceased Person
If you are an executor or administrator required to file a federal income tax return for a deceased
person who was a Colorado resident or a nonresident with Colorado-source income, you must also
file a Colorado income tax return. To request a final determination of tax liability, submit form DR 0253
separately from the return.
Supporting Documentation
Please ensure that you submit any supporting forms, schedules, and documentation as requested
in the instructions. Submitting incomplete documentation will delay the processing of your return. All
Colorado tax forms and guidance publications are available at our official website, Tax.Colorado.gov.
The Department currently does not have a Colorado K-1 form for an estate or trust to report items
allocated to beneficiaries.
If the estate or trust is a partner in a partnership or shareholder in an S corporation, you must submit
a copy of any form DR 0106K with the DR 0105.
Bankruptcy Estate
Submit the DR 0105 with supporting documentation for the estate only. The debtor is required to file
an individual tax return for Colorado income on form DR 0104, but do not submit the DR 0104 with
the estate return. DR 0105 is not used as a transmittal form for the debtor’s DR 0104.

• A copy of the purchase invoice or lease agreement; and
• Proof of permanent Colorado registration.
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 34
below instead.
Line 28 Business Personal Property Credit
If the estate or trust 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 the business personal property on the assessor statement, or find
the 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 divided by an assessment rate of 27.9% would
determine an actual value of $25,000.
If the estate or trust was a partner or shareholder in a partnership or S corporation that paid
business personal property tax, it must include in this calculation its 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 the credit amount, which is equal to the tax on up to $18,000 of the actual value of
the business personal property.
a. If the actual value is less than or equal to $18,000, the 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, if a trust’s share of the actual value is $25,000 and its share of the tax
assessment is $2,000, then $18,000 divided by an actual value of $25,000 and multiplied by a
$2,000 tax assessment would result in a credit of $1,440.
If the estate or trust was a partner or shareholder in a partnership or S corporation that paid
business personal property tax, it must include in this calculation its distributive or pro rata
share of the business personal property tax paid by the partnership or S corporation.

estate or trust income reportable to Colorado by nonresident beneficiaries in Schedule D.
Enter in column 1 the component parts of the federal distributable net income. Enter in column 2 that

Expenses claimed on lines 10 through 15 of federal Form 1041 will be Colorado or non-Colorado
expenses depending on the source of the income to which they are assigned by the fiduciary for
federal income tax purposes.

Enter in column 8 for each nonresident beneficiary, that part of his/her federal distributable net
income from this estate or trust that is from Colorado-sources determined by applying the percentage
in column 7 to the income in column 6. If any other method is used to determine the beneficiary’s

amounts to the nearest dollar.

Schedule E

Schedule E is used to compute the tax of a part-year or nonresident estate or trust. Fiduciaries of
part-year or nonresident estates or trusts shall compute a tentative tax as though the estate or trust
were a resident estate or trust. The actual tax shall be the tentative tax apportioned in the ratio of the
Colorado taxable income to the modified federal taxable income.
First complete lines 1 through 11 of the DR 0105 in accordance with the instructions given for full-year
resident estates and trusts.
Then complete lines 1 through 3 of the federal column of Schedule E using the information from the
federal Form 1041. Complete the federal column using the modifications from line 10 of the DR 0105.
On line 1 of Schedule E, Colorado column, enter the Colorado-source income of the estate
or trust. Expenses shall follow the income to which they were assigned for federal income tax
purposes by the fiduciary.
The distribution deduction and the exemption deduction shall be allowed on line 2 of the Colorado
column in the ratio of the federal distributable net income from Colorado-sources over the total
federal distributable net income.
Include the state tax deduction addback modification relating to prior years and the state tax refund
subtraction modification in the Colorado column in the ratio that the estate or trust income was
Colorado-source income for the year to which the deduction or the refund applies.
For example, if the fiduciary paid $2,000 state tax during 2025 for 2024, and the 2024 estate or trust
income was 40% Colorado-source, include 40% or $800 on line 4 of the Colorado column.
DO NOT include the state tax deduction addback modification relating to taxes paid for the current
year on line 4 of either column.
Complete Schedule E in accordance with the instructions given on the form.

Schedule F

Schedule F is used to compute the alternative minimum tax. The Colorado Alternative Minimum
Tax is the amount by which 3.47% of the Colorado alternative minimum taxable income exceeds
the normal tax. The Colorado alternative minimum taxable income is the federal alternative
minimum taxable income minus the federal AMT exemption and plus the modifications from line
10 of the DR 0105. Do not include modifications that duplicate adjustments made in arriving at
federal alternative taxable income.
Resident estates and trusts complete only lines 1 through 4 of the federal column and lines 7 and 8 of
the Colorado column. Line 1 may be a negative amount.

minimum taxable income. Complete lines 1 through 4 of the federal column as though the estate or
trust were a resident estate or trust.
In computing the amount to enter on line 1, Colorado column, the Colorado-source total income
and the Colorado-source allowable deductions shall be as reported on lines 1 and 2 of Schedule E,
Colorado column. The federal adjustments and tax preference items shall be allocated to Colorado to
the extent they relate to a business being carried out in Colorado or to income from Colorado-sources.
The alternative tax net operating loss deduction shall be allowed to the extent it was from Coloradosources in the year in which it arose.
The income distribution deduction, the estate tax deduction and the federal alternative minimum tax
exemption deduction are allowed in the ratio of the Colorado-source federal distributable net alternative
minimum taxable income to the total federal distributable net alternative minimum taxable income.

Schedule G

Schedule G is used to compute any Fiduciary Tax Credits. Limitation: The credits reported on this
Schedule G are nonrefundable. Consequently, the total credits utilized from this schedule may not
exceed the total tax reported on line 14 of your income tax return, the DR 0105. Enter on lines 5 through
13 the amount(s) of the credit(s) available in Column A and the amount of credit(s) to be applied against
your 2025 liability in Column B. Most unused 2025 credits can be carried forward to tax year 2026.
Line 1 Credit for Tax Paid to Another State
A resident estate or trust may claim credit for income tax paid to another state on income from sources
in that state, including the District of Columbia and territories or possessions of the United States.
Income from intangible assets, such as interest, dividends and gains or losses from the sale or
exchange of securities, unless from a business carried out in the other state, is not considered to be
from sources in the other state. The credit must be claimed on the accrual basis and is limited to the
Colorado tax attributable to such income.
If taxes were paid to two or more states, a separate credit must be computed for each state. The total
credit for taxes paid to other states may not exceed the Colorado tax attributable to non-Coloradosource income. The Department strongly recommends electronic filing for taxpayers with credits
for more than one state. Failure to file electronically may result in delays processing your return.
If income and/or losses are received from two or more other states:
1. Complete lines 1(a) through 1(h) for each state to which taxes are paid, and
2. Complete lines 1(a) through 1(h) (enter “Combined” as name of state) combining all tax paid,
income, and losses from all other states to determine the maximum credit available.
3. The credit will be the lesser of the total credits computed for each state in step 1, or the credit
limitation computed in step 2. Both calculations will be submitted with your return.
Submit a copy of the tax return filed with the other state(s) at Colorado.gov/RevenueOnline or submit
with the DR 1778. If you file a paper return, you must submit the returns, from another state or states,
with your Colorado return.

Line 2 Dual-Resident Trust Credit
A credit is available to a qualifying trust that is a resident trust in both Colorado and another
state. Submit a copy of the tax return filed with the other state at Colorado.gov/RevenueOnline
or submit with form DR 1778. If you file a paper return, you must submit the return(s) from
another state or states with your Colorado return. Additional guidance is available online at
Tax.Colorado.gov/fiduciary-income-tax-guidance-publications.
Line 3 Alternative Minimum Tax Credit
Estates and trusts are allowed a credit of 12% of the federal alternative minimum tax credit for the
same taxable year. Part-year/nonresident estates and trusts must apportion this credit in the ratio
that the modified federal alternative minimum taxable income that gave rise to the prior year federal
alternative minimum tax was considered Colorado alternative minimum taxable income. For example,
if a nonresident estate’s 2024 federal alternative minimum taxable income was 30% Colorado-source,
its credit would be 30% of 12% of the 2025 credit allowed for 2024 minimum tax.

program account administered by CollegeInvest. (§39-22-539, C.R.S.) You must complete and
include form DR 0289 with your return if claiming this credit.
Line 10 Carry forward of prior year credit for employer paid leave of absence for live
organ donation
This credit was allowed only for tax years 2024 and prior. If the allowable credit exceeds the
taxpayer’s tax for the tax year, the excess credit can be carried forward up to five years but
must be applied first to the earliest year possible. Please see section 39-22-540, C.R.S., for
additional information.
Line 11 Nonrefundable Residential Energy Storage Systems Credit
A nonrefundable income tax credit is available for building owners who install qualifying
residential energy storage systems into residential buildings in Colorado and who do not assign
the credit to the seller. The amount of the credit that exceeds the building owner’s income tax
due is not refunded and may not be carried forward to any future years’ income tax due. The
amount of the credit is the amount calculated on line 3 of the Residential Energy Storage
System Credit Eligibility Certification and Assignment Election (DR 1307). Submit the DR 1307
when claiming this credit.
Line 12 Enterprise Zone Contribution Credit
Submit a copy of the credit certificate. For information about the credit, please see Department
