Illinois 1099 Tax Rules
- Rate applied here
- 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 Instacart shoppers
Full-service shoppers carry a heavier deductible load than most gig roles: mileage between stores and homes, insulated totes, and often a second vehicle for over-capacity orders. Batch your store-to-home mileage by shopping region rather than by shopping trip, because the IRS treats a single errand run as one deductible journey and breaking it into too many segments invites scrutiny.
Shopper earnings concentrate around weekends and holidays, so quarterly income is very uneven. Set aside the target percentage at the moment of payout, including tips, because tip income on a 1099-K is reportable and the IRS matches it against your return.
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.
