How the Illinois freelance take-home calculator works
This calculator estimates annual take-home pay for a freelancer in Illinois after federal and state taxes for 2026. The calculation runs in six steps:
- Net profit = annual revenue − deductible Schedule C business expenses.
- Self-employment tax = net profit × 0.9235 × 15.3% (Social Security + Medicare). The deductible half (7.65% of net profit) reduces AGI.
- Federal AGI = net profit + other income − deductible half of SE tax.
- Federal taxable income = AGI − federal standard deduction − 20% QBI deduction (if eligible). Federal income tax is applied to this base.
- Illinois income tax: Illinois starts from federal AGI, subtracts the Illinois standard deduction, and applies the Illinois graduated brackets.
- Take-home = net profit − SE tax − federal income tax − Illinois income tax.
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. State-specific credits, local income taxes (e.g., Ohio municipal, Maryland county, NYC city), and the self-employed health insurance deduction are not modeled. These can meaningfully change your actual tax bill.
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% income tax affect freelance take-home?+
Illinois taxes net income at a flat 4.95% regardless of income level. For a freelancer with $80,000 net profit, Illinois adds approximately $3,500–$4,000 in state income tax. Illinois allows the SE deductible half to reduce state taxable income since it follows federal AGI. There are no graduated brackets — every dollar of income is taxed at the same 4.95% rate.
How does Illinois income tax reduce my freelance take-home pay?+
After federal self-employment tax and federal income tax, Illinois adds another layer of state income tax on your net profit. The combined federal + state tax burden is what reduces your actual take-home pay below the federal-only estimate.
What is the order in which taxes are applied to freelance income?+
Taxes are applied in this order: (1) Self-employment tax on 92.35% of net profit (15.3%); (2) Deductible half of SE tax reduces Adjusted Gross Income; (3) Standard deduction reduces AGI further; (4) Optional 20% QBI deduction on net profit; (5) Federal income tax on taxable income; (6) State income tax based on the state's taxable income definition. The calculator applies all six steps in sequence.
Does the 20% QBI deduction reduce my state income tax in this state?+
The 20% QBI deduction is a federal deduction only. It reduces your federal taxable income but does NOT reduce your Illinois state income tax. The QBI benefit reduces the federal portion of your tax bill, but the state tax is computed separately from the state's own taxable income base.
Can I deduct my freelance business expenses on my state tax return?+
Yes. Illinois generally follows the federal definition of net profit from Schedule C — revenue minus deductible business expenses. This means your deductible expenses reduce your Illinois taxable income as well as your federal taxable income, delivering a combined federal + state tax benefit on every legitimate business deduction.
How much should a freelancer in this state set aside for taxes each quarter?+
In Illinois, a rule of thumb is to set aside 28–35% of net profit for combined taxes — covering federal SE tax (~14.1%), federal income tax (10–22%), and Illinois state income tax. For higher earners in Illinois, the combined rate can exceed 35%. The calculator shows your exact combined rate.
