About Colorado income tax
On top of federal income tax and payroll withholding, Colorado adds a state income tax around 4.4% on wages earned in the state.
The 4.4% figure overstates what typical earners actually pay — for $50,000–$200,000 in Colorado income, deductions and credits usually pull the effective rate a few points lower. Use the calculator above for your exact number.

What This Colorado Income Tax Calculator Does
Enter an income and filing status and the tool works through every layer that gets subtracted before a Colorado paycheck actually lands: state tax, federal tax, and payroll taxes.
Whether you're a Colorado employee double-checking a paystub, a freelancer setting aside money for quarterly taxes, or someone comparing Colorado against another state before a move, this breaks the number down.
Colorado's flat 4.4% rate means the math stays simple year-round, but withholding tables still lag behind real changes in income — a raise or bonus can leave you under-withheld without the paycheck ever looking wrong.
Understanding Your Results
Colorado Tax Owed
The dollar amount you'd owe Colorado for the year after the standard deduction — stack this against what's already been withheld to see whether a refund or a balance due is coming.
Effective State Tax Rate
The share of every dollar earned that actually goes to Colorado, not just the headline rate quoted in news articles. This is the number worth using when comparing states.
After-Tax Income (State)
What survives after Colorado tax is removed, before federal tax and payroll deductions are subtracted. The fully-loaded take-home figure sits above the calculator.
Colorado Income Tax Overview
Colorado keeps it simple with a single flat rate — 4.4% applies to every dollar of taxable income, regardless of how much you earn.
Current Tax Rate: 4.4%
Local Taxes
Some municipalities inside Colorado charge additional local income tax on top of the state rate, which this calculator doesn't account for — check local rules if you live or work in one.
Factors That Affect Your Colorado Tax Bill
A few things move the Colorado number beyond the headline rate:
| Factor | Effect |
|---|---|
| Filing status (single vs. married) | Affects deduction amount and bracket thresholds |
| Dependents | May reduce taxable income through exemptions or credits |
| Self-employment income | Fully taxable; must make estimated quarterly payments |
| Investment income | Generally taxable as ordinary income at state level |
| Retirement distributions | Treatment varies — check current Colorado guidance |
| Residency period | Part-year residents file on pro-rated income only |
Planning Tip
Circle back to the numbers any time income actually changes. Payroll withholding rarely adjusts itself for a raise, bonus, or new side income, and a surprise Colorado balance due at filing time is avoidable with a mid-year look.
Real-World Examples
Example 1: Single Filer, $55,000 Salary
For a $55,000 single-filer salary in Colorado, the standard deduction applies before any tax is calculated, which is why the effective rate ends up noticeably lower than the top-line number.
Example 2: Married Couple, $130,000 Combined Income
A married couple in Colorado filing jointly on $130,000 combined gets the joint standard deduction first, which typically lands their effective rate a bit below what two single filers earning the same amounts separately would pay.
Example 3: Self-Employed Individual, $80,000 Net Profit
Self-employed Colorado residents don't have taxes withheld automatically — a freelancer with $80,000 in net business income has to budget for and submit quarterly estimated payments to avoid a penalty at filing time.
Example 4: Relocating To or From Colorado
Someone earning $250,000 comparing Colorado against Texas, which has no income tax, would see the state-tax difference alone reach well into five figures annually, separate from property or sales tax differences.
Common Colorado Tax Mistakes
Confusing marginal rate with effective rate
Because Colorado taxes every dollar at the same 4.4%, the widely-quoted headline rate and the actual effective rate are one and the same — no bracket math needed.
Ignoring withholding adjustments after a major income change
Colorado withholding doesn't self-adjust when pay changes mid-year — catching a raise or bonus early beats finding out about the gap at tax time.
Not accounting for Colorado-specific deductions or credits
This tool applies the standard deduction, but Colorado may offer additional credits — for dependents, low income, or other circumstances — that a generic estimate won't capture. Current Colorado Department of Revenue guidance fills that gap.
Part-year residents filing as full-year residents
A mid-year move in or out of Colorado calls for part-year resident filing status — only income earned during actual residency gets taxed by the state, not income earned before or after the move.
Tips for Colorado Taxpayers
- Check Colorado withholding once a year, and again after any raise, job change, or major life event.
- If self-employed, set aside Colorado estimated tax quarterly — due dates generally track the federal schedule (April, June, September, January).
- Run the numbers in October or November so there's still time to adjust withholding or make a final estimated payment before year-end.
- Weigh Colorado's full tax picture, not income tax alone — property tax and sales tax vary by state too and affect the real comparison.
