See what your Colorado paycheck is worth after taxes
A $100,000 salary in Colorado does not mean $100,000 will reach your bank account. Federal income tax, Colorado income tax, Social Security, Medicare and Colorado FAMLI contributions can all affect the amount you receive.
Use the calculator below to estimate take-home pay for 2026. Enter your salary or hourly wage, choose a filing status, and add retirement or health deductions if applicable. You can also include the Denver occupational privilege tax when your work qualifies.

What taxes come out of a Colorado paycheck in 2026?
A Colorado employee typically has federal income tax, Colorado income tax, Social Security and Medicare deducted from wages. Most covered employees also contribute toward the state’s Family and Medical Leave Insurance program, known as FAMLI.
Colorado generally uses a flat 4.4% individual income tax rate, but the taxable amount is based on modified federal taxable income. Therefore, 4.4% of gross salary is not always the correct final state tax calculation.
Colorado state income tax
Applied to Colorado taxable income, generally beginning with federal taxable income and accounting for required state additions, subtractions and applicable credits.
Regular federal payroll taxes
The typical employee pays 6.2% Social Security tax on covered wages up to the annual cap and 1.45% Medicare tax on Medicare-taxable wages.
Colorado FAMLI share
For 2026, employees can generally pay 0.44% of wages toward FAMLI, up to the applicable wage ceiling. Employer payment arrangements may differ.
Federal income tax
Federal tax depends on filing status, progressive tax brackets, deductions, credits and other household information.
Unlike federal income tax, which uses multiple brackets, Colorado’s ordinary individual income tax is generally calculated at one state rate. However, exemptions, modifications and credits can still affect the actual amount owed.
What is $100,000 after taxes in Colorado in 2026?
Consider someone earning $100,000 in annual W-2 wages, filing as single, using the $16,100 federal standard deduction, and having no bonus, eligible credits or optional retirement and health deductions.
Assume the normal 0.44% Colorado FAMLI employee share, no Denver occupational tax, no Colorado income modifications and no other income.
| Tax or deduction | Annual amount | Calculation |
|---|---|---|
| Gross annual salary | $100,000.00 | Before taxes |
| Federal income tax | $13,170.00 | 2026 single filing status and standard deduction |
| Colorado income tax | $3,691.60 | 4.4% of estimated $83,900 taxable income |
| Social Security | $6,200.00 | 6.2% of covered wages |
| Medicare | $1,450.00 | 1.45% of wages |
| Colorado FAMLI | $440.00 | 0.44% employee share |
| Estimated annual take-home | $75,048.40 | Before additional benefit deductions |
| Monthly equivalent | $6,254.03 | Annual net divided by 12 |
| Biweekly equivalent | $2,886.48 | Annual net divided by 26 |
Common Colorado salaries before tax
| Annual gross salary | Monthly gross | Biweekly gross | What to review |
|---|---|---|---|
| $40,000 | $3,333.33 | $1,538.46 | Filing status and refundable tax credits |

How Colorado income taxes are calculated for 2026
1. Colorado starts with federal taxable income
Colorado’s tax calculation generally begins with federal taxable income, not simply gross W-2 wages. Required state additions and allowed state subtractions can then produce a different Colorado taxable income.
This distinction matters when you contribute to a traditional retirement account, claim eligible deductions or have income requiring a Colorado-specific adjustment.
2. Federal income tax brackets for 2026
Federal income tax has seven marginal brackets. A higher bracket applies only to the taxable dollars falling within that bracket.
| Federal rate | Single taxable income | Married jointly taxable income |
|---|---|---|
| 10% | $0–$12,400 | $0–$24,800 |
| 12% | Over $12,400–$50,400 | Over $24,800–$100,800 |
| 22% | Over $50,400–$105,700 | Over $100,800–$211,400 |
| 24% | Over $105,700–$201,775 | Over $211,400–$403,550 |
| 32% | Over $201,775–$256,225 | Over $403,550–$512,450 |
| 35% | Over $256,225–$640,600 | Over $512,450–$768,700 |
| 37% | Over $640,600 | Over $768,700 |
3. 2026 federal standard deductions
| Filing status | 2026 basic standard deduction |
|---|---|
| Single | $16,100 |
| Married filing jointly | $32,200 |
| Married filing separately | $16,100 |
| Head of household | $24,150 |
These are basic deductions. Additional standard deductions for eligible taxpayers age 65 or older or blind, and limitations for dependents and married separate filers, are not automatically modeled.
4. Colorado has important federal deduction differences
Colorado follows many federal taxable-income calculations, but not every federal deduction receives identical state treatment.
For tax year 2026, Colorado generally requires an addback when a taxpayer claims the federal deduction for qualified overtime compensation. An ordinary payroll overtime amount included in gross wages is not automatically a separate Colorado addback; the addback concerns the federal deduction actually taken.
The Colorado Department of Revenue’s January 2026 guide also states that the corresponding federal qualified tips deduction does not require that specific state addback.
5. Social Security and Medicare in Colorado
Social Security
Most covered employees pay 6.2% on wages up to the 2026 taxable maximum of $184,500.
Medicare
Regular Medicare tax generally applies to all Medicare-taxable wages, without the Social Security wage limit.
Additional Medicare
An extra tax may apply above the filing-status threshold. Employer withholding begins once that employer pays an employee over $200,000 in Medicare wages.
Employees filing jointly may have a different final Additional Medicare Tax liability from the amount withheld on an individual employer’s payroll. The calculator uses annual filing-status thresholds for its planning estimate.
How much is Colorado FAMLI tax in 2026?
Colorado’s Family and Medical Leave Insurance program helps provide paid leave benefits to qualifying covered workers. Contributions are generally collected through payroll for covered employees.
For 2026, the total program premium is 0.88% of eligible wages. Under the standard contribution structure, the employee portion is 0.44% and the employer portion is 0.44% for employers required to pay an employer share.
Employee contribution
The ordinary employee share that can be deducted from covered payroll. Some employers may cover it instead.
Combined program premium
The total premium rate for 2026. It is not normally an additional 0.88% employee paycheck deduction.
FAMLI employee contribution examples
| Annual eligible wages | Employee 0.44% contribution | Notes |
|---|---|---|
| $40,000 | $176.00 | Assuming full employee share |
| $60,000 | $264.00 | Assuming full employee share |
| $80,000 | $352.00 | Assuming full employee share |
| $100,000 | $440.00 | Assuming full employee share |
| $150,000 | $660.00 | Assuming full employee share |
| $200,000 | $811.80 | 2026 premium calculated up to $184,500 wage base |
The employee FAMLI premium generally stops increasing once the applicable annual wage ceiling is reached. Employers with approved private plans or special arrangements may have different collection procedures.
Does Denver or another Colorado city charge an additional paycheck tax?
Colorado cities generally do not use ordinary city income-tax brackets like some municipalities in other states. However, certain cities impose occupational privilege taxes related to working within the municipality.
Denver occupational privilege tax
Denver’s employee occupational privilege tax is $5.75 for a month in which the employee performs qualifying work in Denver and meets the $500 compensation requirement for that month.
If all 12 months qualify, that is $69 per year. The employer also has a separate obligation, which is not deducted as an additional employee tax.
What about Colorado Springs, Boulder, Aurora or other cities?
Municipal rules vary. You should not assume every Colorado city charges the same occupational tax as Denver. Some municipalities have different rates, qualifying earnings requirements, or no current employee occupational tax.
This estimator automatically includes only the optional Denver employee tax. It does not compute other city occupational taxes or employer-side obligations.
How to calculate Colorado hourly wages after taxes
For hourly employees, begin with the actual hourly wage and the number of hours expected to be paid during the year. Include overtime separately only when it is reasonably predictable.
Regular hourly wages
Multiply your hourly rate by regular weekly hours and paid weeks.
Example: $25/hour × 40 hours × 52 paid weeks = $52,000 in annual gross wages.
Overtime pay
For a qualifying 1.5× overtime situation, multiply overtime hours by 1.5 times the regular hourly rate.
Example: Five overtime hours weekly at a $25 regular rate add $9,750 in annual gross overtime pay over 52 weeks.
What if hours change from week to week?
If your schedule changes, use realistic average weekly hours rather than assuming every week will be identical. Vacation, unpaid leave, seasonal employment and periods without work can change the full-year result.
Employees with tips, commissions or large bonuses should also review actual payroll treatment. The taxable annual total may be different from the withholding that appears on a specific supplemental paycheck.
How to read a Colorado paycheck deduction line by line
| Common paystub label | What it means | What to verify |
|---|---|---|
| FIT / FITW / Federal withholding | Federal income tax withheld from wages | Form W-4 and payroll withholding method |
| CO SIT / Colorado withholding | Colorado income tax withheld | Form DR 0004, W-4 and state withholding rules |
| OASDI / Social Security | Employee Social Security tax | 6.2% and annual wage cap |
| MED / Medicare | Regular Medicare tax | 1.45% and possible Additional Medicare withholding |
| FAMLI / CO PFML | Colorado paid family and medical leave premium | Employee share, covered wages and employer plan |
| 401(k) / 403(b) | Retirement contribution | Traditional or Roth treatment |
| Health / Medical / FSA / HSA | Selected health benefit deductions | Whether the benefit is qualified pre-tax or after-tax |
| Denver OPT | Qualifying employee occupational privilege tax | Qualifying Denver employment months |
Why does my paycheck show more withholding than this calculator?
Employers calculate withholding using payroll rules, pay dates, the relevant employee certificates and year-to-date information. This calculator estimates annual income tax liability and divides net income across pay periods for planning.
Federal withholding is not necessarily identical to eventual federal income tax liability. The same distinction applies to Colorado withholding and final Colorado income tax.
How to review and update Colorado paycheck withholding in 2026
Colorado has an optional state withholding certificate, Form DR 0004. It works alongside the federal Form W-4. If you do not submit DR 0004, your employer generally calculates Colorado withholding using the federal W-4 information under the state withholding rules.
- Review your latest paycheck. Find year-to-date gross wages, federal income tax withholding, Colorado withholding, Social Security, Medicare and FAMLI amounts.
- Check federal withholding. Open the official IRS Tax Withholding Estimator. Enter your current job, wages, withholding and relevant family or tax information.
- Review Form W-4 if an adjustment is recommended. Use the IRS recommendations and provide a completed W-4 to your employer or payroll department.
- Open Colorado Form DR 0004. Download the official 2026 Colorado Employee Withholding Certificate. Read the instructions to determine whether a state-specific change is appropriate.
- Consider jobs, deductions and credits. The Colorado certificate can be particularly useful when you expect Colorado credits, have relevant nonstandard deductions, earn substantial other income or need to adjust state withholding.
- Give the certificate to your employer. Submit the completed DR 0004 to payroll. Your employer uses it with the applicable Colorado withholding rules, including the 2026 DR 1098 worksheet.
- Verify the next paycheck. Compare your federal and Colorado withholding with the previous paystub. Recheck after a job change, marriage, significant salary increase or other major tax change.
When is updating DR 0004 helpful?
- You last reviewed your Colorado withholding several years ago.
- You changed jobs or started an additional job.
- Your income or filing status changed significantly.
- You anticipate state tax credits or a different federal deduction.
- You expect substantial income beyond your current wages.
- You received an unexpectedly large Colorado refund or balance due.
Employers can consult the official 2026 Colorado DR 1098 withholding worksheet.
Colorado resident, part-year resident or remote worker?
Full-year Colorado resident
Colorado generally taxes qualifying income of residents, subject to its taxable-income rules and applicable adjustments or credits.
Part-year resident
A person moving into or out of Colorado may need to allocate income and apply state residency rules rather than using a full-year Colorado tax assumption.
Nonresident working in Colorado
Income earned from work performed in Colorado may be subject to Colorado income tax, even if the worker resides elsewhere.
Working remotely for a Colorado employer
Your employer’s headquarters alone does not necessarily determine where all wages are taxable. Residency, actual work location and relevant state sourcing rules can change the result.
Workers in more than one state should review possible credits for income taxes paid to another state and the appropriate filing requirements.
Colorado tax return forms
Most qualifying Colorado individual taxpayers use Form DR 0104. The return generally begins with federal taxable-income information and includes Colorado adjustments, credits, withholding and payment amounts.
The official Colorado Individual Income Tax Guide explains resident, nonresident, tax calculation, withholding and related filing rules.
Why your actual Colorado net pay may not match
| What seems wrong | Likely reason | What to check |
|---|---|---|
| My paycheck is lower than estimated. | Health insurance, retirement, other deductions or additional withholding is missing. | Match each paystub deduction to the calculator inputs. |
| Colorado income tax looks too high. | State withholding elections differ from annual liability. | Review DR 0004 and payroll’s state withholding calculation. |
| FAMLI is missing or different. | Employer-covered premium, special arrangement or different covered wages. | Ask payroll about the applicable FAMLI plan. |
| Federal tax is much higher. | Multiple jobs, W-4 settings, spouse income or supplemental payroll withholding. | Use the official IRS withholding estimator. |
| Denver OPT appears unexpectedly. | Qualifying work performed in Denver. | Verify city work location and applicable monthly wages. |
| My bonus paycheck seems heavily taxed. | Supplemental wage withholding differs from annual income tax allocation. | Review the payroll method and annual total income. |
| My state tax changed after moving. | Residency, state sourcing or work location changed. | Review the Colorado nonresident/part-year resident rules. |
Practical checklist before making a payroll change
- Confirm the pay period on the paystub.
- Separate federal income tax from Social Security and Medicare.
- Check whether retirement contributions are traditional or Roth.
- Check the correct annual amount of health deductions.
- Review Colorado FAMLI and local occupational taxes separately.
- Confirm W-4 and DR 0004 elections with payroll.
- Compare year-to-date amounts, not only one unusually large or small paycheck.
10 FAQs about the Colorado Tax Calculator 2026
1. What is the Colorado income tax rate for 2026?
The Colorado individual income tax rate used for 2026 is 4.4%. It generally applies to Colorado taxable income, which begins with federal taxable income and includes required state modifications. Applicable tax credits can reduce the final liability.
2. How much is $100,000 after taxes in Colorado?
Under the single-filer assumptions in the worked example, $100,000 in 2026 W-2 wages results in approximately $75,048.40 annual take-home pay, or $2,886.48 biweekly. Actual pay depends on benefits, filing status, credits, withholding and local taxes.
3. Does Colorado have a flat income tax?
Yes. Colorado generally uses a flat individual income tax rate, unlike the progressive federal bracket system. The amount subject to that rate can still change because of state additions, subtractions and credits.
4. What is the Colorado FAMLI deduction for 2026?
The 2026 combined FAMLI premium is 0.88% of covered wages. The ordinary employee share is 0.44%, subject to the applicable wage limit and employer or private-plan arrangements.
5. Does Denver have an extra paycheck tax?
Denver has an employee occupational privilege tax of $5.75 for qualifying months of employment in Denver when applicable compensation requirements are met. The tax is separate from Colorado’s state income tax.
6. How do I calculate Colorado biweekly take-home pay?
Enter your annual compensation, filing status and deductions, then select biweekly pay. This estimator calculates annual net income and divides by 26. Actual withholding may differ by employer and pay period.
7. Does a 401(k) reduce Colorado income tax?
Eligible traditional 401(k) contributions generally reduce federal taxable wages and can also reduce Colorado taxable income through the state’s federal starting point. Roth contributions are different, and traditional 401(k) contributions generally do not avoid regular FICA taxes.
8. Are overtime wages taxed in Colorado in 2026?
Yes, overtime wages are generally taxable. Colorado also has an addback rule for the federal qualified-overtime deduction claimed for 2026. This calculator does not automatically apply that special federal deduction or addback.
9. Do Colorado remote workers owe state income tax?
Tax treatment depends on residency, work location and state income-sourcing rules. A full-year Colorado resident can generally have Colorado taxable income even when working remotely for an employer located elsewhere. Nonresident situations require separate review.
10. Why is my Colorado payroll withholding different from this calculator?
Employers use withholding worksheets, Form W-4, optional Colorado Form DR 0004, payroll frequency and year-to-date details. This calculator estimates annual liability instead of reproducing every employer withholding method, so paystub results can differ.
