Colorado paycheck breakdown

Calculation parameters: Single filer, standard federal deduction, zero additional withholdings, $75,000 annual salary, 24 pay periods. State tax estimates account for Colorado's adherence to the federal standard deduction. Models use current data sourced from the Colorado Department of Revenue and Department of Labor and Employment.

The Colorado flat tax system

The Colorado Department of Revenue enforces a flat income tax rate, eliminating the progressive bracket structures found in most neighboring states. For 2026, the state income tax is locked at a flat 4.40% on all taxable W-2 wages.

Because Colorado conforms to the federal standard deduction ($16,100 for a single filer in 2026), the 4.40% rate is not applied to the very first dollar earned. Instead, a single earner making $75,000 is taxed a flat 4.40% on their remaining $58,900 of taxable income. To establish precise withholding for this flat rate, employees submit Colorado's specific Form DR 0004 to their payroll department, allowing them to calculate accurate exemptions without relying on the federal W-4.

The FAMLI payroll deduction

Colorado legally mandates that employees fund the Family and Medical Leave Insurance (FAMLI) program through direct payroll deductions. Administered by the Colorado Department of Labor and Employment, the total FAMLI premium is typically split evenly between the employer and the employee.

For the employee, the statutory share is 0.45% of gross wages (half of the 0.90% total premium). On a $3,125 semi-monthly paycheck, this triggers an unavoidable $14.06 deduction. Unlike 401(k) contributions, this premium is exacted on gross wages before standard tax allowances are considered, meaning every working resident in a covered enterprise must pay it from their first paycheck of the year.

Denver's Occupational Privilege Tax (OPT)

While Colorado generally avoids broad municipal income taxes, specific cities target payroll directly through head taxes. The City of Denver assesses an Occupational Privilege Tax (OPT) on anyone working within city limits, regardless of where they sleep at night.

Employees earning more than $500 a month in Denver are liable for a $5.75 monthly OPT deduction. This is not a percentage-based income tax; it is a flat fee stripped directly from the paycheck to fund municipal infrastructure. Similar, though differently priced, occupational privilege taxes exist in Aurora and Greenwood Village.

Colorado state income tax rates (2025)

Colorado charges 4.4% on every dollar of taxable income, with no bands to cross, once the $15,000 standard deduction has come off. On $75,000 that works out to $2,442, an effective 3.26% of gross, and nothing at all is due below $15,957.

Colorado take-home pay by salary

Annual take-home at six salary points for a single filer deferring 6% into a 401(k). The CO column climbs in a straight line from $994 to $7,612, because the same rate applies at both ends.

Formula & Logic — Colorado Withholding

Take-home pay is gross salary minus five separate withholdings, each with its own rule and its own base. Two are federal and fixed nationwide, two are FICA payroll taxes with their own ceilings, and one is set by Colorado. Colorado applies a single flat rate of 4.4% to taxable income, so unlike a progressive state your marginal and average state rates converge as income rises. On $138,000 the state takes $5,048, an effective 3.66% of gross. A flat rate makes the arithmetic simple but it applies from the first taxable dollar, so the deduction matters more than the bracket structure. Note also that the 401(k) contribution comes out before federal income tax is computed but not before Social Security and Medicare — a detail that trips up most hand calculations.

Take-home = Gross − 401(k) − Federal income tax − Social Security − Medicare − State taxFederal = brackets applied to (gross − 401(k) − $15,000 standard deduction)State income tax = (gross − 401(k) − state standard deduction) × 4.4%

where:

Gross
annual salary before any deduction — $138,000 in the example below
401(k)
6% deferred = $8,280; reduces federal and state taxable income, but not FICA
Federal
$20,380 — 2026 single brackets after the $15,000 standard deduction
Social Security
6.2% of wages up to the $184,500 2026 wage base = $8,556
Medicare
1.45% of all wages, no ceiling = $2,001 (+0.9% above $200,000)
State
Colorado — Flat 4.4% income tax = $5,048

Assumptions: Single filer, standard deduction, 6% traditional 401(k), no other pre-tax benefits, credits or local income tax. Health premiums, HSA contributions and city taxes (where they exist) would each change the result. 2026 federal figures.

Step-by-Step Example: $138,000 in Colorado

Rather than a round number, this example uses the salary Colorado's own housing costs imply: a median-priced $545,000 home carries a $3,216 monthly payment, and the 28% front-end ratio lenders underwrite to puts that within reach at about $138,000 a year. Here is where that salary actually goes for a single filer contributing 6% to a traditional 401(k).

  • Gross salary$138,000 (28% rule on a median home)
  • Filing statusSingle, standard deduction
  • 401(k)6% ($8,280)
  • Colorado regimeFlat 4.4% income tax
  1. Start from gross and take out the 401(k). $138,000 × 6% = $8,280 deferred, leaving $129,720 subject to federal income tax.
  2. Federal income tax. After the $15,000 standard deduction, the 2026 single brackets produce $20,380 — an effective 14.8% of gross.
  3. Social Security. 6.2% on wages up to the $184,500 wage base = $8,556. This is charged on the full salary, not the post-401(k) figure.
  4. Medicare. 1.45% with no ceiling = $2,001.
  5. Colorado income tax. Flat 4.4% income tax applied to income after the 401(k) and the state deduction = $5,048.
  6. Subtract everything. $138,000 − $8,280 − $20,380 − $8,556 − $2,001 − $5,048 = $93,736 take-home.

Result$93,736 a year — $7,811 a month, $3,605 per biweekly cheque

Total tax burden is $35,984, an effective 26.1% of gross — of which Colorado takes 3.66%. The $8,280 401(k) deferral is not a tax; it is still your money.

Frequently Asked Questions — Colorado Paychecks

Generally, yes. If your employer has 10 or more employees nationwide, they must remit the full 0.90% premium, funding half of it themselves while deducting the remaining 0.45% from your paycheck. Employers with fewer than 10 employees do not pay the employer share, but they must still deduct and remit your 0.45% portion.
Because Colorado operates a universal flat tax rather than progressive brackets, supplemental wages such as performance bonuses or severance pay are generally withheld at the exact same 4.40% rate as your regular salary.
Yes. Because Colorado taxable income begins with your federal adjusted gross income, any pre-tax deferrals you make into a traditional 401(k) or 403(b) automatically lower your state tax burden. The 4.40% rate is applied to the smaller, post-deferral amount.
