Colorado uses a flat-rate state income tax structure, meaning the same marginal rate applies across income levels for withholding purposes. Your Colorado state withholding amount scales with your gross pay and filing status, but it does not climb through multiple state tax brackets the way progressive systems do. Federal income tax and FICA still apply on top of state withholding.

Most W-2 paychecks in Colorado include several standard withholding categories. Your employer uses IRS Publication 15-T tables for federal income tax, then applies payroll taxes and any state or local taxes required for your work location.
Your annual salary is the same whether you are paid weekly, biweekly, semi-monthly, or monthly, but each paycheck amount differs because the number of pay periods changes. Weekly pay divides your annual gross into 52 checks; biweekly into 26; semi-monthly into 24; and monthly into 12. Withholding tables account for pay frequency, so per-check federal and state amounts may not be a simple annual total divided evenly. Comparing offers or budgeting often requires looking at both per-paycheck net and annual take-home together.
Filing status — Single, Married Filing Jointly, or Head of Household — changes the withholding brackets your employer uses for federal income tax and, in most states with income tax, for state withholding as well. Two employees earning the same salary in Colorado can have different net pay if their filing status or W-4 entries differ. Updating your W-4 after a marriage, divorce, or dependent change is the most common way to align withholding with your expected tax situation.

Net pay is the amount you actually receive after payroll deductions. It starts with gross pay, then subtracts federal income tax, Social Security, Medicare, state or local tax, and any voluntary deductions.
Take-home pay equals gross pay minus taxes and deductions. A paycheck calculator applies federal withholding, FICA, state income tax, local taxes where applicable, and pre-tax or post-tax deductions in the correct order.
Gross pay is earnings before deductions. Net pay is what remains after payroll taxes, benefits, retirement contributions, insurance premiums, garnishments, and other paycheck deductions.
Pre-tax deductions can reduce taxable wages before income tax is calculated. A 401(k), HSA, or FSA may lower federal and state taxable income, but some deductions do not reduce Social Security or Medicare wages.
Post-tax deductions are taken after payroll taxes are calculated. Examples may include Roth 401(k) contributions, certain insurance payments, wage garnishments, or after-tax benefits.
Colorado has a flat state income tax rate. As of 2025, the rate was 4.25%, reduced from 4.4% in 2024 due to TABOR requirements. Confirm the exact 2026 flat rate at colorado.gov/tax.
Colorado does not specify a separate supplemental rate. Employers typically withhold Colorado income tax on supplemental wages using the same flat rate that applies to regular wages.
Colorado uses federal taxable income as the starting point for state withholding, so the federal standard deduction indirectly applies. Colorado does not publish a separate state standard deduction for withholding formula purposes.
Yes. Denver imposes an Occupational Privilege Tax (OPT) on employees earning more than $500 per month in Denver. Several other Colorado cities also levy an OPT. Check your work city for applicability.
Yes. Colorado's Family and Medical Leave Insurance (FAMLI) program requires employee contributions. For 2026, confirm the current employee contribution rate and wage base at famli.colorado.gov.
Because Colorado uses a flat tax rate, filing status affects withholding primarily through the federal withholding step, which Colorado uses as a base. Different federal allowances can change the Colorado withholding amount.
Gross pay is earnings before taxes. Net pay is what remains after federal income tax, Social Security, Medicare, Colorado flat state tax, FAMLI contributions, any Denver OPT, and benefits deductions.
Update your W-4 whenever your filing status, number of dependents, or income situation changes significantly. Colorado does not require a separate state withholding form — the federal W-4 drives Colorado withholding.

ExactTakeHome starts with gross pay, applies your pay frequency, subtracts eligible pre-tax deductions (401k, HSA, FSA) from federal taxable wages, calculates federal income tax withholding using IRS Publication 15-T percentage method tables, applies Social Security (6.2% up to $184,500 wage base) and Medicare (1.45%) taxes on gross wages, then applies Colorado state income tax using the 2026 withholding tables from the Colorado Department of Revenue. Local tax is applied where available (NYC, Philadelphia, Columbus OH). Final take-home is an estimate of paycheck withholding, not your final tax return liability.
Calculate your Colorado take-home pay after federal withholding, FICA, state taxes, local taxes, and pre-tax deductions.
Pre-tax deductions like 401(k), HSA, and health insurance premiums reduce your taxable wages before federal income tax is calculated. This means you pay less tax on every paycheck — not just defer the money.
Why take-home increases: A 6% 401(k) contribution on $75,000 reduces taxable wages by $4,500, cutting both federal income tax and Colorado state income tax on that amount. Social Security and Medicare still apply to the original gross wages.
Pay frequency changes your paycheck size, not your annual salary. Withholding tables annualise each paycheck, so weekly and monthly results may differ slightly from biweekly.

Colorado paychecks can also include state-specific payroll items such as paid family and medical leave contributions. Certain cities have local payroll-related taxes, so a Denver-area paycheck may not look identical to one elsewhere in the state.
Colorado uses a flat state income tax structure for wages. Your final paycheck still depends on federal withholding, FICA, benefits, and any local payroll items.
Colorado's paid family and medical leave program is funded through payroll contributions. It is not the same thing as state income tax, even though both can appear on a pay stub.
