Colorado Part Year Worksheet

  1. Enter all full-year amounts of federal income and adjustment items in the table below.
    • Enter all income amounts before adjustment amounts because Colorado adjustments are calculated based on the ratio of Colorado to total earned or gross income, depending on the particular adjustment.
    • "From" and "Thru" entries indicate when the account was active during the year.
  2. If W-2 or 1099 state withholding does not accurately indicate the income distribution between multiple states, modify the entry of the W-2 or 1099 in TaxSlayer to indicate the correct income amounts and match those distributions in this calculator. DO NOT adjust the withholding amounts.
  3. Entry of annuities/pensions/Social Security/RR Retirement benefits automatically calculate the correct exclusion amounts for Colorado Subtractions from AGI using age limits and owner as needed.
    • For annuities and pensions enter the taxable amounts.
    • For Social Security and RRB Tier I benefits enter the gross amounts; the taxable amount will be calculated.
  4. The Colorado allocation will be calculated automatically based on residency dates, account dates and income ratios as appropriate for the entry type.
    • If ownership is joint (J), each half will be distributed based on each of the taxpayer and spouse residency dates and/or income ratios.
  5. If manual adjustment is needed, change the amount in either of the two state result boxes, the other will adjust automatically.
    • Click "CALC" to restore the calculated distribution for that line.
  6. Finally, enter the amounts in the "Colorado Part Year Input" list into TaxSlayer in the Colorado "Income Subject To Tax" and "Subtractions From Income" form.
