Rate schedule source
Colorado Department of Revenue, 2026 Form DR 0004 Colorado Employee Withholding Certificate (applies 4.40%); Individual Income Tax Guide, January 2026 edition; corroborated by pack B (guide rate table, 2025 = 4.4%) (https://tax.colorado.gov/sites/tax/files/documents/DR_0004_2026.pdf)
Tax year of the schedule
2026
Worked out from Franchise Tax Board, 2025 California Tax Rate Schedules and 22 other sources.
Statutory base rate 4.40% of Colorado taxable income (s.39-22-104(1.7)(c) C.R.S.), applied by the DOR 2026 Form DR 0004. TABOR CARRY-OVER: the rate can be temporarily reduced under s.39-22-627 C.R.S. when a TABOR surplus is certified (2024 was 4.25%); neither pack could determine whether a temporary reduction applies to tax year 2026 and the DOR guide rate table stops at 2025, so the 4.40% here is the unreduced statutory rate and the entry stays flagged unverified until the DOR publishes the 2026 rate. Colorado starts from FEDERAL TAXABLE INCOME, so the federal standard or itemized deduction is already embedded - the standard deduction is null and no separate state deduction or personal exemption must be applied (the DR 0004 "standard allowance" of $14,000 / $22,000 / $30,000 is a payroll-only figure).
Some 2026 figures for Colorado are not yet confirmed from the state's own 2026 publication and are carried from 2025; the note above names them. Treat the figure as indicative and confirm it with the Colorado revenue authority before relying on it.
An estimate from each state's published rate schedule. State credits, add-backs, part-year and non-resident apportionment, and local taxes other than New York City are not modelled. Check your state return or a tax professional before relying on it.

How this is worked out

4 steps
  1. Colorado (tax year 2026): Colorado applies its flat rate to FEDERAL TAXABLE INCOME (after the federal standard or itemized deduction), not to AGI.
  2. Income 85000 less deduction 0 = taxable income 85000
  3. 4.4% on 85000 (0 to and above) = 3740
  4. Total state and local tax = 3740
