What we do not model
For Colorado: Taxable income starts from federal taxable income (after the federal standard deduction). The figures above exclude local and municipal income taxes, tax credits, itemized deductions, phase-outs, alternative minimum tax, state disability insurance, and the Form W-4 details that change real withholding. They are an estimate, not tax advice — see the full disclaimer for what the model does and does not cover.
Common questions
- How does Colorado income tax work?
- Colorado uses a single flat rate of 4.4% on its own taxable income, after a standard deduction of $16,100 for single filers or $32,200 for married couples filing jointly. There are no brackets to climb, so every additional dollar is taxed at the same rate.
- What is the top Colorado income tax rate?
- The top Colorado rate is 4.4%, and it only applies to income above the highest bracket threshold shown above — not to your whole salary. The rate on your first dollars is 4.4%.
- What is the Colorado standard deduction for 2026?
- $16,100 for single filers and $32,200 for married couples filing jointly; there is no separate dependent exemption. Taxable income is what remains after that deduction, and it is what the brackets are applied to.
- What is the take-home pay on $100,000 in Colorado?
- For a single filer paid biweekly with no 401(k) deferral and no health premiums, a $100,000 salary in Colorado leaves $2,903.40 per paycheck — $75,488.40 a year, an effective rate of 24.5% after $13,170 of federal income tax, $3,692 of Colorado tax and $7,650 of FICA.
- Do remote workers pay Colorado income tax?
- A Colorado resident is generally taxed by Colorado on wages earned anywhere, including wages for a remote job whose employer sits in another state. Days worked physically outside Colorado can matter in some cases, and a non-resident working in Colorado is generally taxed on income earned here. Nothing here is tax advice — the details depend on your situation.
- Does Colorado have local income taxes?
- Taxable income starts from federal taxable income (after the federal standard deduction). This calculator does not model that layer — treat the number above as state plus federal only.
