What actually reaches your account after federal tax, Social Security, Medicare, and Colorado’s own brackets — with every line shown separately, so you can check it against a real payslip.
One paycheck line by line, and the pay period in which Social Security stops and every remaining cheque gets bigger.
What a raise leaves you after tax, and what a bonus is withheld at versus what it actually costs.
The bracket ladder drawn out — every bracket, the income that landed in it, and why a raise can never leave you with less.
What actually comes out of an American paycheck in 2026 — federal brackets, FICA, and all fifty states' own rules — plus the take-home spread on one identical salary, computed rather than asserted.
A bonus arrives with a third missing and everyone concludes bonuses are taxed punitively. They are not. Withholding and tax are different things, and the difference comes back to you.
Convert every offer to take-home before you answer, match offers across state lines, and counter with scripts that work — with the arithmetic computed rather than asserted.
Self-employment tax is 14.13% of profit, not 15.3%. Price your rate, reserve on receipt, hit the safe harbour, and know when an S-corp is worth it — computed, not asserted.
Colorado guide
Almost every article about Colorado's income tax leads with the rate: a flat 4.4%, one number for everyone. The rate is the least interesting thing about it.
What matters is what the 4.4% is charged on. Colorado's return begins at line 1 with "Enter Federal Taxable Income from your federal income tax form" — not your salary, not your adjusted gross income, but the figure that already has the federal standard deduction taken out of it.
That is why Colorado records no standard deduction and no personal exemption of its own. It does not need them. It inherits the federal ones, which for 2026 shelter $16,100 for a single filer — several times what most states allow.
On $85,000 a single filer pays $3,032 and takes home $65,596.
A note before you start. This is general education, not tax advice. Federal figures are tax year 2026, from IRS Revenue Procedure 2025-32 and the Social Security Administration; Colorado's rate and base come from this site's own sourced 50-state dataset, citing C.R.S. 39-22-104 and the Department of Revenue's January 2026 Individual Income Tax Guide. Every dollar figure is computed by the same engine the site's calculators use, on a single filer taking the standard deduction with no dependents or pre-tax deferrals unless stated. TABOR refunds, sales tax and property tax are discussed qualitatively.
Across incomes, single filer:
The statutory rate is 4.4% and nobody in that table pays it. At $175,000 the effective rate is 4.00%; at $30,000 it is 2.04%. The gap is the $16,100 the federal deduction shelters, which is a large share of a small salary and a small share of a large one.
This is the mechanism worth understanding, because it explains results that otherwise look wrong.
