Illinois 1099 Tax Rules

- 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 real estate agents
Commission-based agents have an unusually clear deduction set: the vehicle used to show property, marketing materials and photography, brokerage fees, and licensing and continuing-education costs. Mileage is the largest single item for an agent who drives to listings daily, and the standard mileage rate is usually more favourable than actual expenses for a vehicle that is also used personally.
Commission income is the most volatile of any role in this catalogue: a single closing can represent a year of income. Never set a quarterly voucher from a good quarter alone. Use the trailing two-year average, and remember the IRS compares your payments against a year that may have had a closing you did not repeat.
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.
