Understanding your paycheck in Colorado involves navigating federal, state, and local tax regulations, as well as other deductions that impact your take-home pay. The ADP Colorado Paycheck Calculator is a tool designed to help employees and employers estimate net pay after accounting for these factors. Below, we break down the key components of paycheck calculations in Colorado, including tax calculations, official guidelines, and practical considerations for accurate results.

Federal Income Tax

Federal income tax is withheld from your paycheck based on your gross income, filing status, and allowances claimed on your IRS Form W- Internal Revenue Service (IRS) uses a progressive tax system, meaning higher earnings are taxed at higher rates. For 2025, federal tax brackets range from 10% to 37%, depending on your taxable income. The IRS provides detailed withholding tables and formulas for employers to calculate the exact amount. Employees can adjust their W-4 to increase or decrease withholdings, ensuring their paycheck aligns with their tax obligations. For the most accurate information, refer to the IRS Publication 15 (Circular E), which outlines employer tax responsibilities.

Colorado State Income Tax

Colorado imposes a flat state income tax rate of on taxable income for the 2025 tax year, as confirmed by the Colorado Department of Revenue. Unlike federal taxes, which vary by income level, Colorado’s flat rate simplifies calculations. Taxable income is determined after subtracting federal standard or itemized deductions and other allowable exemptions. For example, a single filer with a gross income of $50,000, claiming the standard deduction of $14,600 (for 2025), would owe state tax on $35,400, resulting in approximately $1, in state income tax. Employers withhold this amount based on the information provided in the employee’s Form CO-W-4, Colorado’s equivalent of the federal W-

FICA Taxes

Federal Insurance Contributions Act (FICA) taxes fund Social Security and Medicare. For 2025, Social Security tax is on income up to $168,600, and Medicare tax is on all income, with an additional for individuals earning over $200,000 (or $250,000 for married couples filing jointly). Employers match these contributions, but only the employee’s portion is deducted from the paycheck. For instance, an employee earning $60,000 annually would pay $3,720 in Social Security tax and $870 in Medicare tax. The Social Security Administration provides updates on wage bases and rates annually.

Other Deductions

Beyond taxes, paychecks may include deductions for benefits like health insurance, retirement contributions (e.g., 401(k) plans), and wage garnishments. Colorado law requires employers to comply with federal and state garnishment rules, which can affect net pay. Employees should review their pay stubs to understand these deductions and consult their HR department for specifics on voluntary contributions.
