Where do these Colorado numbers come from?
Rates and deductions come from Tax Foundation, 2026 State Individual Income Tax Rates and Brackets (Feb 2026 snapshot), updated for 2026 legislation in GA, SC, WV, UT and AR, updated where a state changed its law later and checked against the state's own revenue department where we could reach it. The section above lists exactly what each estimate leaves out.
What these Colorado figures leave out
- Colorado can temporarily lower its rate in a year when state revenue exceeds its TABOR limit; the standard 4.4% rate is used.
- Some local payroll or wage taxes are not included.
- Assumes no dependents, no itemized deductions and no state tax credits beyond those described.
- Head-of-household filers use the single-filer schedule and deduction, except where a state's own head-of-household amount is built in.
- State payroll taxes such as disability or family-leave insurance are not included.
- Reflects state law as we last reviewed it (September 2026). Legislatures sometimes change rates mid-year, so confirm the current figures with your state's revenue department before relying on them.
Checked against official sources (September 2026): the 4.4% flat rate still applies — the bills that would have cut it to 4.0% (HB24-1065) or 4.25% (SB25-138) did not pass — Colorado General Assembly and Department of Revenue. Official source.
