$55,000 After Taxes in Colorado (2026)

A single filer paid $55,000 in Colorado has $38,900 of federal taxable income after the $16,100 standard deduction. The top slice of that income falls in the 12% federal bracket, which starts at $12,400 of taxable income, and federal income tax comes to $4,420, or 8.04% of the salary.

Payroll tax is federal and the same in Colorado as everywhere else: on $55,000 of wages it is $4,208, made up of $3,410 of Social Security at 6.2% of every dollar and $798 of Medicare at 1.45%.

Colorado taxable income is $38,900, and Colorado taxes it at its flat 4.4% rate. State income tax is $1,712, 3.11% of the salary. Colorado applies a single flat rate to *federal* taxable income, not to a separately computed state taxable income. This is unusual: most flat-tax states build their own base.

Altogether $10,339 of a $55,000 Colorado salary goes to tax, an effective total rate of 18.80%, which leaves $44,661 a year: $3,722 a month, $1,718 every two weeks, $859 a week, or $21 an hour over 2,080 hours.

At $55,000, Colorado ranks 29th of 51 jurisdictions for take-home pay, highest first. A no-tax state leaves $1,712 more a year, and the median state $57 more than Colorado. The lowest take-home at $55,000 is $42,783, in Oregon, $1,878 less than in Colorado.

Across the state line the same $55,000 leaves a single filer: Wyoming $46,373, $1,712 more; Nebraska $44,750, $89 more; Kansas $44,103, $558 less; Oklahoma $44,443, $218 less; New Mexico $44,953, $292 more; Utah $44,419, $242 less; Arizona $45,391, $730 more.

These Colorado figures treat the whole $55,000 as wages, take the standard deduction, claim no dependents and include no federal credits. A pre-tax 401(k) contribution or health premium would lower taxable income and raise take-home; a second income or itemized deductions would change it again.
