How the Illinois hourly rate calculator works
This calculator finds the minimum hourly rate needed to reach your target after-tax income in Illinois for 2026. It integrates federal taxes and Illinois 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) − Illinois income tax(G) − non-deductible overhead = target take-home
The minimum hourly rate = G ÷ (billable weeks × hours per week).
Illinois income tax in the solver
Illinois income tax applies to G minus the SE deductible half minus the Illinois standard deduction ($2,925 single). The solver recomputes at each iteration.
Scope and limitations
Not included: Excludes Illinois local taxes and the 1.5% Personal Property Replacement Tax (PPRT) that applies to S-Corps and partnerships at entity level. SDI is not applicable in Illinois. Age-related additional exemption ($1,000 per qualifying condition) is excluded. 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 IL Dept. of Revenue — Income Tax Rates (4.95% flat rate) for 2026.

Frequently asked questions
How does Illinois's flat 4.95% rate affect the minimum hourly rate?+
Illinois's flat 4.95% income tax rate adds a consistent amount to the required gross revenue at every income level. At $70,000 target take-home (single, 1,440 billable hours), IL adds approximately $3,000–$4,000 to the gross revenue needed — roughly $2–$3/hour more than in a no-income-tax state. The flat rate makes Illinois's impact on hourly rate easy to estimate.
How does Illinois income tax affect my minimum hourly rate?+
Illinois 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 Illinois 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 − Illinois 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 Illinois 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 Illinois'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 Illinois 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.
