Biweekly (every two weeks, 26 pay periods) is not the same as semi-monthly (twice a month, 24 pay periods). Semi-monthly checks are slightly larger because there are two fewer of them per year.

Where every dollar goes

Here's the honest breakdown for a married filing jointly filer on $600,000 in Colorado (2026). The IRS takes $136,269 in federal income tax — that's after the $32,200 standard deduction knocks your taxable income down. FICA (Social Security plus Medicare, the combined line you always see on your pay stub) adds another $23,289. Colorado collects $24,983 in state income tax.

Add it all up and $184,541 goes to taxes, leaving $415,459 in take-home pay. That's the number that actually lands in your bank account.

Sources: IRS Rev. Proc. 2025-32 (federal brackets for 2026); SSA Contribution and Benefit Base (2026); Colorado Rev. Stat. §39-22-104(1)(b) — flat individual income tax rate of 4.40% on Colorado taxable income, applied to filers' federal taxable income (federal AGI minus federal standard deduction) per the statutory definition. Rate has been 4.40% since TY2022 (post-Proposition 116 reduction); no further phase-down enacted for TY2026. Colorado does not have a state-level standard deduction or personal exemption — the federal standard deduction has already been applied upstream when computing federal taxable income, and the federal personal exemption is $0 under TCJA. The calculator encodes Colorado's standardDeduction equal to the federal SD per filing status to preserve the correct math through stateAdjustedGross..

Frequently Asked Questions

What is the take-home pay on $600,000 in Colorado?
For a married filing jointly filer earning $600,000 in Colorado (tax year 2026), the take-home pay is approximately $415,459 per year after $136,269 federal income tax, $23,289 in FICA (Social Security and Medicare), and $24,983 in state and local taxes. This is an effective tax rate of 30.76%.
Does this include pre-tax deductions like 401(k), HSA, or health insurance premiums?
The numbers on this page assume no pre-tax deductions. If you contribute to 401(k), HSA, healthcare FSA, or dependent care FSA, your actual federal tax will be lower. Use the live calculator to model exact pre-tax deductions — it applies them to your federal taxable wages and, for verified states (currently Pennsylvania, Michigan, and California), to your state taxable wages too.
Why does my actual paycheck differ from this estimate?
Common reasons: (1) pre-tax deductions your employer withholds — if you haven't entered them in the live calculator, your paycheck shows lower taxes; (2) W-4 withholding is an IRS safe-harbor estimate, not your true tax owed — you reconcile at filing; (3) state and local tax credits (EITC, property tax relief, child tax credit) that we don't model; (4) post-tax deductions like Roth 401(k) contributions or wage garnishments; (5) multiple jobs or side income changing your effective bracket.
What HSA contribution limit should I use — self-only or family?
The live calculator caps HSA input at the 2026 family limit ($8,750). If you have self-only HDHP coverage, your limit is $4,400 — enter no more than that. The age-55+ HSA catch-up contribution ($1,000) is not yet modeled. HSA contributions are pre-tax for FICA only when made through a §125 cafeteria plan (standard employer payroll deduction); standalone HSA contributions are post-FICA-tax.
Why is the Dependent Care FSA limit $7,500 now?
The One, Big, Beautiful Bill Act (signed July 2025) raised the Dependent Care FSA limit from $5,000 to $7,500 starting tax year 2026. For married filing separately, the limit is $3,750 (raised from $2,500). The live calculator applies the correct limit based on your filing status. This is the first DCFSA limit increase since 1986.
Can I add 401(k) or HSA catch-up contributions for older taxpayers?
Not yet. The live calculator exposes only the regular limits ($24,500 for 401(k), $8,750 for HSA family). Age-50+ adds $8,000 to 401(k) under §414(v); age-60-63 adds $11,250 under SECURE 2.0; age-55+ adds $1,000 to HSA under §223(b)(3). Catch-up support is on the roadmap; for now, treat the calculator's results as an upper bound on tax for older filers using catch-up.
What does 'verified' mean on this site?
A state or city is verified when its tax tables, rates, and brackets have been cross-checked against the official Department of Revenue publications for the given tax year. We list our primary-source citations on every page. Unverified jurisdictions are excluded from search indexing (with a noindex tag) and labeled "coming soon" — we don't show approximate data presented as authoritative. As of tax year 2026, six US jurisdictions are verified.
What is the difference between effective and marginal tax rates?
Your effective tax rate (30.76%) is your total tax divided by your gross income — the average percentage of your income that goes to taxes. Your marginal tax rate (41.75%) is the rate that applies to your next dollar of income. Marginal rates are always equal to or higher than effective rates in a progressive tax system.
How does Colorado state income tax work?
Colorado imposes a flat individual income tax of 4.40% under Colorado Rev. Stat. §39-22-104(1)(b). The rate has been 4.40% since TY2022 (post-Proposition 116 reduction) and applies uniformly to all filers regardless of income. Unlike most states, Colorado uses federal taxable income (federal AGI minus federal standard deduction) as its starting point for state taxable income — this calculator applies the federal standard deduction to your wages before the 4.40% Colorado rate to match this statutory mechanic. Pre-tax 401(k), HSA, healthcare FSA, and dependent care FSA contributions all reduce your Colorado state taxable income via federal-AGI conformity (Colorado has no add-backs on Form DR 0104).
Why does Colorado not have a state standard deduction line?
Colorado's tax base is federal taxable income, which already reflects the federal standard deduction (TY2026: $16,100 single / $32,200 MFJ). Adding a separate state standard deduction would double-count the reduction. This calculator preserves the correct math by encoding Colorado's standard deduction equal to the federal standard deduction per filing status — the result matches what you'd compute by taking your federal taxable income directly and multiplying by 4.40%. Colorado also has no per-filer or per-dependent personal exemption (the federal $0 personal exemption under TCJA flows through).
What is TABOR and how does it affect my Colorado refund?
Colorado's Taxpayer's Bill of Rights (TABOR, Article X §20 of the Colorado Constitution) requires the state to refund revenue collected above a constitutional cap. TABOR refunds are paid as post-tax rebates the year after collection — either via a six-tier sales-tax-refund mechanism, a temporary income-tax-rate reduction at filing time, or other mechanisms. This calculator does not model TABOR refunds because they are post-tax and do not affect the rate at withholding or in-paycheck math. Filers receive any applicable TABOR refund when they file their Form DR 0104 the following year. Your actual Colorado take-home in years with a TABOR refund will be slightly higher than this calculator shows.
What if I itemize federal deductions instead of taking the standard deduction?
This calculator applies the standard deduction ($32,200 for Married Filing Jointly). If you itemize using IRS Schedule A — typically when your mortgage interest, state and local taxes (capped at $10,000), charitable donations, and qualified medical expenses exceed the standard deduction — your federal taxable income will differ. We don't model itemization because it requires line-by-line input and is highly individualized. Use IRS Schedule A worksheets or consult a tax professional for itemized scenarios.
How accurate is this calculator?
Federal income tax, FICA (Social Security + Medicare + Additional Medicare), and state income tax are computed from official 2026 IRS, SSA, and state Department of Revenue tables. This page assumes no pre-tax deductions, no itemized deductions, no tax credits, and W-2 wage income only. The live calculator supports 401(k)/HSA/FSA pre-tax deductions; itemized deductions, credits, self-employment income, and multi-state allocation aren't modeled.
