How the Colorado hourly rate calculator works
This calculator finds the minimum hourly rate needed to reach your target after-tax income in Colorado for 2026. It integrates federal taxes and Colorado state income tax into a single binary-search solver.
The solver logic
The calculator runs 60 iterations of binary search to find the gross annual revenue G where:
G − SE tax(G) − Federal income tax(G) − Colorado income tax(G) − non-deductible overhead = target take-home
The minimum hourly rate = G ÷ (billable weeks × hours per week).
Colorado income tax in the solver
Colorado income tax (4.4%) applies to federal taxable income (G minus SE deductible half minus federal standard deduction). The solver recomputes this at each iteration as G changes.
Scope and limitations
Not included: Excludes Colorado local taxes and any TABOR-triggered temporary rate adjustments that may apply in a given year. SDI is not applicable in Colorado. Local income taxes, self-employed health insurance deduction (IRC §162(l)), and state-specific credits are not modeled. These can change your actual required rate.
Use this for planning, not filing. Federal figures from IRS Rev. Proc. 2025-32; state figures from CO Dept. of Revenue — Individual Income Tax (4.4% flat rate, 2026) for 2026.

Frequently asked questions
How does Colorado's flat 4.4% rate affect the minimum hourly rate?+
Colorado's flat 4.4% rate on federal taxable income adds a predictable, consistent amount to the required gross revenue. At $70,000 target take-home (single), CO adds approximately $3,000–$4,000 to the annual gross revenue needed, translating to roughly $2–$3 per billable hour more than in a no-income-tax state.
How does Colorado income tax affect my minimum hourly rate?+
Colorado state income tax is included in the binary-search solver that computes your minimum hourly rate. Because state income tax increases your total tax burden, you need to charge a higher hourly rate to achieve the same take-home income than if you lived in a no-income-tax state. The calculator accounts for all three taxes — SE tax, federal income tax, and Colorado income tax — in a single integrated calculation.
How does this calculator find the minimum hourly rate?+
The calculator uses a binary search algorithm (60 iterations, converges to within $0.01) to find the gross annual revenue where: (gross revenue − SE tax − federal income tax − Colorado income tax − non-deductible overhead) = your target take-home. It divides that gross revenue by billable hours per year to give you the minimum hourly rate.
Why is my minimum hourly rate in this state higher than federal estimates?+
Adding Colorado state income tax to the calculation means you need to earn more gross income to cover the additional tax and still reach your target take-home. The state tax effectively increases the required gross revenue, which increases the minimum hourly rate. The exact increase depends on your income level and Colorado's rate structure.
Should I include the 20% QBI deduction in my hourly rate calculation?+
Most freelancers qualify for the 20% QBI deduction if their taxable income is below the 2026 threshold ($201,775 single / $403,550 MFJ). Checking the QBI box lowers your federal taxable income, which reduces federal income tax and therefore the gross revenue you need to charge. The QBI deduction does not reduce Colorado state income tax. Enable QBI in the calculator to see the lower required rate when you qualify.
What non-deductible overhead should I include?+
Non-deductible overhead includes personal costs your income must cover but that aren't deductible as business expenses: individual health insurance premiums (if not deductible under IRC §162(l)), personal equipment, and other non-business costs. Deductible business expenses (software, home office, professional fees) should NOT be entered here — they reduce your Schedule C net profit and are already factored into how the calculator models SE tax.
