How to use the Colorado Paycheck Calculator

Review the 2026 IRS and Colorado source dates, certificate entries, which deductions are actually FICA-exempt, every year-to-date wage base, locality, exemptions, and whether the employer pays any employee program premium.

Read the estimate basis, estimated net pay, federal and FICA items, Colorado income tax withholding, supported local and payroll-program items, and total estimated taxes and premiums.

Formula

Colorado estimated net pay = gross pay − pre-tax deductions − 2026 federal withholding − Social Security − Medicare − calculated Colorado withholding − supported local taxes and employee payroll premiums.

Example

If a Colorado pay period has $2,000 gross pay, no pre-tax deduction, and the displayed federal, FICA, state, and local taxes total $410, estimated net pay is $1,590.

Assumptions and limitations

Colorado withholding must use the selected year’s Department of Revenue worksheet, rate, and employee adjustment inputs. This is a 2026 planning estimate, not payroll or tax advice; employer benefit treatment, reciprocity, exemptions, supplemental wages, and unlisted local programs can change the actual check.
Colorado Paycheck Calculator treats the entered values as estimates and does not infer missing project, account, or personal details.
Calculations retain working precision except where the cited method requires an intermediate rounding step; displayed values are then formatted separately. Source rules and dated rates must be rechecked when they change.
