How Your CO Paycheck Works
Colorado paychecks start with federal income tax withholding under IRS Publication 15-T, using the wage-bracket or percentage method tied to Form W-4, pay frequency, and taxable wages. FICA is calculated separately: 2026 employee Social Security is 6.2% up to the $184,500 wage base, and employee Medicare is 1.45% with no wage cap. Employers must add the 0.9% Additional Medicare Tax after an employee's Medicare wages exceed $200,000 in the calendar year. Colorado uses a flat state income tax rate of 4.4% of Colorado taxable income, per the Colorado Department of Revenue. Colorado also has FAMLI payroll premiums: for 2026, the total FAMLI premium is 0.88% of wages, generally split 0.44% employee and 0.44% employer, with employee deductions capped at the Social Security wage base. Whether FAMLI appears in your paycheck calculation depends on your employer's enrollment status; some small employers and self-insured plans operate differently. FAMLI deductions may apply but are not included in this estimate. Estimates assume standard 2026 withholding, single filing status, and no pre-tax deductions; actual paycheck may differ.
