The solid line is what you keep in Colorado; the dashed line is the median of all 51 jurisdictions at the same salary (single filer). Where the lines cross is where Colorado stops being the better deal.
Figure B Take-home pay as salary rises
If every dollar you earned from January 1 went to tax, this is the day you'd stop paying and start keeping.
Figure C The tax year, day by day
You work until Mar 19 — day 78 of 365 — to pay your total 2026 tax bill of $15,999. Everything you earn after that is yours.
On $75,000, a single filer here keeps $59,001. The median state keeps $59,018 — you are $17 behind. See all 51 states ranked by take-home pay.

Single filer, no pre-tax deductions. The $75,000 row is the calculator's default above.
The state-specific rules behind the numbers above — the things a generic calculator gets wrong about Colorado.
Colorado has no state standard deduction of its own. The state return starts from federal taxable income — the figure after the federal standard deduction ($16,100 for a single filer in 2026) or federal itemized deductions — then applies Colorado additions and subtractions before the flat 4.40% rate. The practical effect: Congress effectively sets Colorado's deduction, and federal changes such as the One Big Beautiful Bill Act flow straight into Colorado tax bills without any vote in Denver.

Colorado is one of the few states that taxes Social Security, but with a large age-based subtraction. Taxpayers 65 and older can subtract the entire amount of Social Security included in federal taxable income. Taxpayers 55 to 64 can also subtract it in full if their AGI is no more than $75,000 (single) or $95,000 (joint); above those limits the subtraction falls under the general pension cap. The broader pension and annuity subtraction is up to $20,000 a year at ages 55–64 and up to $24,000 at 65+, and Social Security subtracted counts against those caps for other pension income — so retirees must plan the two subtractions together.

Colorado's Taxpayer's Bill of Rights (TABOR), added to the state constitution in 1992, caps how fast state revenue can grow — roughly inflation plus population growth — and requires any revenue above the cap to be refunded to taxpayers unless voters approve keeping it. Refunds are usually delivered through the income tax return (and in some years partly as a temporary rate reduction), which is why Coloradans sometimes receive a TABOR refund on top of an ordinary refund. TABOR also requires voter approval for tax increases, which is why Colorado's flat rate changes only at the ballot box.

Colorado has no county income taxes, but a few cities levy local employment taxes: Denver charges an occupational privilege tax (a small flat monthly amount on employees and a matching amount on employers for work in the city), and Greenwood Village, Glendale and a few others have similar small flat levies. Local sales taxes, by contrast, are significant — combined state, county, city and district sales tax rates vary widely by address.

A flat 4.40% of Colorado taxable income. Colorado starts from your federal taxable income, so the federal standard deduction ($16,100 for a single filer in 2026) is already baked in before the 4.40% is applied.
Colorado starts there, yes — there is no separate Colorado standard deduction. Your federal standard deduction or itemized deductions reduce the starting figure, then Colorado additions and subtractions apply. That is why a change in federal tax law can move your Colorado bill even when Colorado law doesn't change.
It depends on your age. At 65 or older you can subtract all of the Social Security included in your federal taxable income. At 55 to 64 you can subtract it in full if your AGI is $75,000 or less (single) or $95,000 (joint); above those limits it counts toward the $20,000 pension and annuity subtraction cap.
On $75,000 of wages as a single filer, this page estimates Colorado state tax of $2,592, federal income tax of $7,670 and FICA of $5,738 — total tax $15,999 and take-home pay of $59,001. Any TABOR refund for the year would come back on top of that when you file.
TABOR — the Taxpayer's Bill of Rights in Colorado's constitution — caps state revenue growth at inflation plus population growth. Revenue above the cap must be refunded to taxpayers (through the return, sometimes partly via a temporary rate cut) unless voters approve letting the state keep it. You must file a Colorado return to claim your share.
Ages 55 to 64 can subtract up to $20,000 a year of qualifying pension and annuity income (including IRA and 401(k) distributions); ages 65 and over can subtract up to $24,000. Social Security subtracted counts toward those caps for the pension subtraction, so the two breaks interact.
