This form, new in 2016, was previously part of the CO104 form. It is used to record subtractions from Colorado income.
The total subtractions from this form carries to line 5 of the CO DR 0104 form.
TaxSlayer entry: State Section
 State Income Tax Refund (FYI Income 12):
The taxable portion of the Colorado refund from Form 1040 line 10.
 U.S. Government Interest (FYI Income 20):
Automatically filled in as specified in TaxSlayer interest and dividend forms.
[3,4] Pension subtraction (FYI Income 25):
TaxSlayer calculates and enters this amount.
- $20,000 of annuities and pensions for each person is non-taxable for ages 55-64, $24,000 for 65 and over or
- beneficiaries of any age (such as a widowed spouse or orphan child) who are receiving a pension or annuity because of the death of the person who earned the annuity or pension.
- Conversion of a traditional IRA to a ROTH IRA can also be included in this subtraction.
- Also included are taxable Social Security benefits, but see FYI Income 18 for how to calculate the amounts for each person.
- Nonqualified deferred compensation payments received by persons 55 years of age or older qualify for the pension subtraction even if such payments may be reported as wages for federal income tax purposes to the extent they qualify as retirement income.
- ☣ SOFTWARE ERROR – If there is an entry in box 11 of a W-2, it should, but does not, properly carry across to the CO pension exclusion lines 3(TP) or 4(SP).
- If the exclusion amount is already at the $20,000/$24,000 limit, there is no need to fix the problem.
- To fix the software error, find the Pension Exclusion Worksheet (immediately following the CO 104) and manually add the amount to the Allowed Pension Exclusion (up to the $20,000/$24,000 limit). Then, enter in the State Section > Subtrations from Income > Other Subtractions Tax Slayer page for the affected taxpayer’s exempt pension line.
 Colorado Source Capital Gain Subtraction (FYI income 15):
- Taxable capital gains from the sale of real or tangible personal property located in Colorado.
- Acquired after May 8, 1994 but before June 4, 2009 and owned continuously for five years prior to the sale date.
 College tuition contribution (CollegeInvest, 529 plan) (FYI Income 44):
- The amount claimed can be no more than the Federal taxed income.
- Contributions to other states are not eligible.
- Starting in 2014, there is an option that permits a refund to be applied to a 529 plan. See instructions on the College Invest site.
 Charitable contribution deduction (FYI Income 48):
Always enter in Schedule A forms
- If not itemizing using Schedule A, total contributions (minus $500) can be deducted on the Colorado 104 – enter on the A Details worksheet.
- It is possible that by paying slightly more federal tax (by not itemizing) and less CO tax that the overall tax payment will be smaller, so try both ways.
- Any single non-cash contribution greater than $500 claimed on the CO return must have an appraisal or 1098C (for vehicles) scanned or sent in. (See the Colorado 104CR resource page for more information on how).
 Qualified Reservation Income:
- Income derived wholly from reservation sources by a recognized tribal member and included as taxable income.
- Tribal membership proof, residence and source of income must be submitted every 3 years.
 PERA or DPSRS Subtraction (FYI Income 16):
- If contributions were made between 7/1/1984 – 12/31/1986 (PERA) or any time in 1986 (DPSRS), a subtraction may be taken.
- The taxpayer will have to provide you the records to show what was contributed and what has already been subtracted.
 Railroad Retirement Subtraction (FYI Income 25):
Tier I and Tier II Railroad retirement pensions are not taxable in the state of Colorado.☣ SOFTWARE ERROR – Tier 1 (social security equivalent) is not distinguished from other social security amounts. Both Tier 1 and Tier 2 amounts are included in the 20K/24K pension exclusion and should not be. This produces erroneous results for the CO state return. Correct this using the RRB Worksheet.
- If there is a federal taxable amount for the RR pensions, that amount is subtracted from state income.
- If there is other pension income, the full $20,000/$24,000 still applies to that pension source.
 Wildfire Mitigation Measures Subtraction(FYI Income 65):
- Must be the owner of the property
- Allows the lesser of: 50% of expenses, $2500, or owner’s Federal taxable income.
