Not tax advice: This calculator provides estimates for educational purposes only. It is not tax, legal, or financial advice. Your actual paycheck is determined by your employer's payroll system and your W-4. Consider speaking with a qualified tax professional about your situation.
Assumptions disclosed: Estimates use an annualized model: your annual tax is calculated from 2026 federal and state rules and divided evenly across your paychecks. Actual per-paycheck withholding uses IRS Publication 15-T tables and may differ. Bonuses, overtime, credits, deductions beyond the fields shown, and local taxes (except an amount you enter) are not modeled. Amounts are rounded to the nearest cent.
Data sources / updated: Federal parameters: IRS Revenue Procedure 2025-32 (2026 tax year). State parameters: official state department of revenue sources, verified 2026-10-12; sources per state are listed in the methodology. Page last updated: 2026-10-20.
How your take-home pay is calculated in Colorado
Every figure on this page starts from annual pay. The calculator adds up a full year of gross pay, subtracts the pre-tax deductions entered (traditional 401(k), HSA contributions and health insurance premiums), and applies the 2026 federal brackets after the standard deduction — $16,100 for single filers and $32,200 for married couples filing jointly in the federal model used here. Social Security is calculated at 6.2% of FICA wages up to the 2026 wage base of $184,500, and Medicare at 1.45%, with the additional 0.9% Medicare tax on FICA wages above $200,000 (single) or $250,000 (married). Traditional 401(k) contributions do not reduce FICA wages; HSA contributions and health premiums paid through payroll do. The annual tax is then divided evenly across the paychecks in the chosen frequency. That is an annualized estimate: an employer payroll system withholds per paycheck using IRS Publication 15-T tables, the employee W-4 and year-to-date wages, so a real paycheck differs somewhat from the figures here, and the annual totals are the reliable comparison.
One further limit: the effect of HSA contributions and health premiums on state tax varies by state and is not modeled in this version; on the state side, only the 401(k) contribution is applied. All amounts are before tax credits and are rounded to the nearest cent.
In the verified 2026 model, Colorado applies a flat rate of 4.4% to taxable income. Taxable income is pay after traditional 401(k) contributions and a standard deduction of $16,100 for single filers or $32,200 for married couples filing jointly.
The Colorado calculation on this page is deliberately plain: subtract the 401(k) contribution, subtract the standard deduction, multiply by 4.4%. There are no bracket thresholds to cross-check and no special branch in the model, which makes Colorado a good control case when comparing states. A pay raise changes the state line by 4.4 cents per additional taxable dollar, and a larger 401(k) contribution reduces the state line by the same 4.4% of the added contribution, before the federal effect is counted.

Worked example: take-home pay on $80,000 in Colorado
The example below uses the Colorado benchmark salary with a 5% traditional 401(k) contribution, paid every two weeks. Because the rate is flat, the interesting comparison on the stub is between the marginal rate and the effective rate in the annual summary: the standard deduction pulls the effective rate on the full salary noticeably below the 4.4% headline.
Benchmark salary $80,000 — BLS QCEW 2024 average annual pay for Colorado, rounded to the nearest $1,000.
| Line | Per paycheck | Annual |
|---|---|---|
| Gross pay | $3,076.92 | $80,000.00 |
| 401(k) contribution | $153.85 | $4,000.00 |
| Federal income tax | $303.46 | $7,890.00 |
| Social Security | $190.77 | $4,960.00 |

What is the Colorado state income tax rate for 2026?

Taxable income is pay after traditional 401(k) contributions and a standard deduction of $16,100 for single filers or $32,200 for married couples filing jointly. With no graduated brackets, every additional dollar of taxable pay is taxed at the same 4.4%.
Does Colorado have local income taxes that change take-home pay?
A small number of Colorado cities levy local taxes on wages, and those are not built into the state model on this page. The calculator provides a local tax field where an annual amount can be entered directly; the stub then shows it as its own line. The state figure itself stays the flat 4.4% calculation described in the tax notes on this page.
How does a 401(k) contribution change take-home pay in Colorado?
A traditional 401(k) contribution is subtracted before federal income tax is calculated, so the federal line falls. Social Security and Medicare are worked out on pay before the 401(k) contribution, so the FICA lines stay the same. On the state side, this calculator applies the contribution inside the verified Colorado model, as described in the tax notes on this page. The stub recalculates every line when the contribution changes.
What changes between biweekly and semimonthly pay?
The annual tax is the same in this annualized model; only the division changes. Biweekly pay means 26 paychecks a year and semimonthly means 24, so each semimonthly check is larger while the yearly total lands in the same place. The frequency strip above the annual summary shows the same pay divided all four ways: weekly, every two weeks, twice a month and monthly.
