Wondering how much house you can afford with your net pay?
Mortgage Loan CalculatorColorado runs a flat income tax rather than the tiered brackets most states use — every resident pays the same 4.4% marginal state rate regardless of income level, which keeps the math simple but offers no relief for lower earners. That flat rate has actually been trimmed a few times over the past several years as state revenue triggers kicked in, dropping from 4.63% down to today's 4.4%. Compared with neighbors, Colorado sits in the middle of the pack: it's noticeably cheaper than California or nearby New Mexico brackets that climb higher, but it's not a bargain like income-tax-free Wyoming just across the border. Front Range cities including Denver, Boulder, and Aurora also layer on small local occupational privilege taxes (often just a few dollars per paycheck), so your real take-home may be a touch lower than a state-only estimate suggests. Use the calculator below with the pre-filled 4.4% rate as your starting point, then adjust it upward slightly if you want to account for federal withholding and any local flat fees your employer deducts.
🏆 Decoding Your Colorado Paycheck
Everything you need to know about using this calculator and the math behind it.
How it Works
Strips away estimated federal and Colorado state taxes plus common deductions from your gross salary to reveal your actual take-home (net) pay.
The Formula
Net Pay = Gross Pay − (Federal Tax + Colorado State Tax (4.4%) + FICA + Pre-tax Deductions).
Pro Tip
Check whether your city or county adds any local wage tax on top of the 4.4% state rate before you finalize your budget.
Frequently Asked Questions
Does Colorado have a flat income tax? +
Yes. Colorado is one of a small handful of states with a single flat income tax rate rather than progressive brackets. As of the current tax year the rate is 4.4%, applied to all taxable income regardless of how much you earn. This is simpler to calculate than bracket-based systems but means high earners don't get the same relief low earners do from a lower first-bracket rate.
How does Colorado compare to neighboring states? +
Colorado's 4.4% flat rate is lower than California's top marginal rate (13.3%) and generally lower than Nebraska or Kansas brackets at higher incomes, but higher than income-tax-free neighbors like Wyoming. Utah also runs a flat tax, currently just below Colorado's. Overall Colorado lands as a moderate-tax state for income purposes.
Do Denver or other Colorado cities add local income tax? +
Denver, Aurora, and a few other Colorado municipalities charge an Occupational Privilege Tax — a small flat monthly fee (often $2-$5.75 from the employee plus a matching employer share) rather than a percentage-based local income tax. It's modest but does slightly reduce take-home pay beyond the state 4.4% rate.
Has Colorado's tax rate changed recently? +
Yes. Colorado's flat rate has stepped down several times in recent years — from 4.63% to 4.55% and then to 4.4% — driven by state revenue-limit provisions under TABOR (the Taxpayer's Bill of Rights) that can trigger automatic rate reductions when collections exceed certain thresholds.
What deductions reduce my Colorado taxable income? +
Colorado generally starts from your federal taxable income and applies state-specific additions and subtractions, including deductions for certain retirement income, 529 plan contributions, and other state-specific adjustments. Because the state uses a flat rate, any reduction to taxable income saves you exactly 4.4% cents on the dollar.
