Instructions for Alternative Minimum Tax
Individual taxpayers are subject to a Colorado alternative
minimum tax equal to the amount by which 3.47% of their
Colorado alternative minimum taxable income exceeds
their Colorado normal tax.
Colorado alternative minimum taxable income is the federal
alternative minimum taxable income modified by any
applicable additions and subtractions. Enter on line 2 of
form DR 0104AMT the sum of lines 3 through 7 from form
DR 0104. Enter on line 4 of form DR 0104AMT the sum
of all subtractions entered on the DR 0104AD excluding
the State Income Tax Refund (line 1, DR 0104AD) and
any interest paid by the State of Colorado or any political
subdivision thereof that is in federal alternative minimum
taxable income. On DR 0104AMT - Computation Schedule,
do not enter any amount on line 2 or line 4 that duplicates
any income or adjustment made in arriving at federal
alternative minimum taxable income.
For additional information about calculating Colorado
alternative minimum tax, please review the Individual
Income Tax Guide at Tax.Colorado.gov
Ordinarily, you will have a Colorado alternative minimum
tax if you have a federal alternative minimum tax.

Part-Year and Nonresidents

In the case of a nonresident, the Colorado alternative
minimum tax shall be apportioned in the ratio of the modified
federal alternative minimum taxable income from Colorado
sources to the total modified federal alternative minimum
taxable income. In the case of a part-year resident, the
Colorado alternative minimum tax shall be apportioned in
the ratio of the modified federal alternative minimum taxable
income applicable to that part of the year the taxpayer was
a resident plus the modified federal alternative minimum
taxable income from Colorado sources, if any, during that
part of the year the taxpayer was a nonresident over the
total modified federal alternative minimum taxable income.
Adjustments relative to the standard deduction and
itemized deductions would be Colorado adjustments to
the extent of the Colorado adjusted gross income ratio
as determined on line 34 of form DR 0104PN. Other
adjustments would be Colorado adjustments to the extent
they relate to items of income from Colorado sources. Tax
preference items are Colorado items to the extent they
relate to a business being carried on in Colorado.
Use the worksheet below to calculate the apportionment
percentage if you are a part-year resident or nonresident
individual. Carry the amount from line 6 of the worksheet to
line 6 of the DR 0104AMT.
