- 4.95% Flat Rate
- Statutory bracket
- Single 4.95% rate
Illinois applies a flat 4.95% individual income tax rate, having flattened its brackets and made the rate permanent in 2024. For a high-earning contractor this is materially less than the state would have charged under the old 4.95% top bracket, because the old structure taxed only the top slice.
Local taxes: Chicago alone can add up to 3.25% in city, county, and transit authority income taxes, and dozens of other Illinois municipalities levy their own. A Chicago-based 1099 worker can face a combined rate above 8% once all local layers stack.

Tax Strategy for notary publics
A notary's two core costs are the state commission renewal fee and the required journal, seal, and insurance. These are fully deductible and are easy to overlook precisely because they are small and routine. Notaries who also perform loan signing add document preparation time, mobile-notary travel mileage, and business insurance to the deduction schedule.
Mobile notary work is often the higher-margin and more seasonal part of the trade, with signing volume tied to the home purchase cycle. Loan-signing income can appear in a single month and then vanish for a quarter, so divide the trailing-twelve-month total rather than extrapolating a strong signing month.
To avoid underpayment penalties, pay at least 90% of your current-year tax, or 100% of last year's total tax — 110% if your prior-year AGI was above $150,000.

That total covers self-employment tax (15.3% on 92.35% of net profit), federal income tax on the remainder after your standard deduction, and Illinois adds roughly 5.0% on your taxable Illinois income. The percentage is measured against gross income rather than net profit because that is the number that actually reaches your bank account and the number you can safely divert.

Illinois requires quarterly estimated payments via Form IL-1120-ST if you owe $500 or more. The Illinois Department of Revenue aligns its due dates with the federal calendar.
What expenses can a notary public write off in Illinois?

Because Illinois taxes self-employment income at 5.0%, each deduction reduces both your federal and your Illinois liability, so a deduction is worth more than its face value.
