If you drive for Uber in Illinois, your tax bill has two main pieces: federal self-employment tax of 15.3% on your net earnings, and Illinois income tax of 4.95% on the same net figure. Nothing is withheld from what Uber pays you, so you’re expected to send both the IRS and the Illinois Department of Revenue quarterly estimated payments through the year. Chicago adds a per-trip Ground Transportation Tax, but Uber collects that from passengers directly, so it affects what shows up on your annual summary rather than what you personally owe. The rest of this guide walks through each layer, the deductions that bring the net number down, and the deadlines that trigger penalties if you miss them.
The Three Layers of Tax You’ll See
Federal Self-Employment Tax
Uber treats you as an independent contractor, which means no employer is splitting Social Security and Medicare with you. You pay both halves yourself through self-employment tax: 15.3% of your net earnings, broken into 12.4% for Social Security and 2.9% for Medicare.1Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) For 2026, the Social Security portion only applies to the first $184,500 of net self-employment income.2Social Security Administration. Contribution and Benefit Base The Medicare portion has no cap. If your total earnings cross $200,000 as a single filer or $250,000 married filing jointly, an extra 0.9% Medicare surtax kicks in on top.
You get one break on this: you can deduct half of your self-employment tax as an above-the-line adjustment on your federal return.3Internal Revenue Service. Self-Employed Individuals Tax Center That lowers your federal adjusted gross income, and because Illinois starts its calculation from your federal AGI, it lowers your state bill too.
Illinois State Income Tax
Illinois applies a flat 4.95% rate to net income at every earnings level.4Illinois General Assembly. Illinois Compiled Statutes 35 ILCS 5/201 – Tax Imposed Your “net income” for this purpose is your gross fares minus allowable business deductions like mileage and phone costs. A driver with $30,000 of net income owes roughly $1,485 in state tax before any credits.
You file Form IL-1040 if a federal return was required, or if your Illinois base income exceeds the personal exemption allowance ($2,850 for 2025).5Illinois Department of Revenue. 2025 IL-1040 Instructions Most active drivers clear that line quickly. If you live outside Illinois but drive within the state, you still owe Illinois tax on the Illinois-source income. The IL-1040 starts with your federal AGI, which already includes the Schedule C net profit from driving, so there’s no separate state business form to fill out.
Chicago’s Ground Transportation Tax
For trips that start or end inside Chicago, the city charges a Ground Transportation Tax under Chapter 3-46 of the Municipal Code. Uber collects it from the passenger at the time of the ride and sends it to the city. The money doesn’t pass through your bank account.
Why it matters anyway: the fees still appear in gross receipt totals on your Uber tax summary. If you don’t recognize them for what they are, you can mistake pass-through tax collected from riders for your own earnings. The per-trip rates stack by ride type, time, and location, with higher amounts in the downtown Congestion Zone and a $5.00 surcharge on any ride touching O’Hare, Midway, Navy Pier, or McCormick Place.6American Legal Publishing. Municipal Code of Chicago 3-46-030 – Tax Imposed7City of Chicago. Ground Transportation Tax (7595) A single evening ride to O’Hare in the Congestion Zone can carry $7.63 in combined fees. Review your weekly earnings statements against your trip count so these amounts don’t inflate what looks like earned income.
Quarterly Estimated Payments
Since nothing is withheld, both the IRS and Illinois expect you to pay through the year rather than once in April.
Federal Estimates
You owe federal estimated payments if you expect to owe $1,000 or more in tax after withholding and credits. Payments are due April 15, June 15, September 15, and January 15 of the following year. To avoid an underpayment penalty, pay at least 90% of your current-year tax or 100% of your prior-year tax (110% if your AGI topped $150,000).8Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty If your driving income swings season to season, using last year’s total liability as your safe harbor is usually easier than forecasting the current year.
Illinois Estimates
Illinois requires estimated payments when you expect state tax over $1,000 after withholding and credits.9Illinois Department of Revenue. 2026 IL-1040-ES Estimated Income Tax Payments for Individuals Due dates match the federal schedule. You can pay the full year with the first installment or split evenly across four.
Illinois uses its own safe harbor: no penalty if you pay 90% of current-year liability or 100% of prior-year liability, provided the prior year was a full 12 months and you filed a return showing tax owed.10Illinois Department of Revenue. Pub-103, Penalties and Interest for Illinois Taxes First-year drivers have no prior number to anchor to, so aim for 90% of what you expect to owe.
Deductions That Lower What You Owe
Every legitimate business expense cuts both your federal and Illinois taxable income, because the state return starts from the federal profit figure.
Mileage
The IRS standard mileage rate for 2026 is 72.5 cents per business mile.11Internal Revenue Service. IRS Sets 2026 Business Standard Mileage Rate at 72.5 Cents Per Mile, Up 2.5 Cents That single rate covers gas, insurance, depreciation, and maintenance. Twenty thousand business miles produce a $14,500 deduction.
You can instead track actual vehicle expenses and deduct the business-use percentage, but there’s a catch: you must pick the standard mileage rate in the first year the car is used for business if you want the option open later.12Internal Revenue Service. Topic No. 510, Business Use of Car Most rideshare drivers find the standard rate simpler and often more generous. Tolls and parking fees for business trips are deductible on top of either method, so hold onto those receipts.
Phone and Supplies
Your phone is a tool of the job, but the IRS only lets you deduct the business-use portion. If you estimate 60% of your use is for driving, you deduct 60% of the bill. Also deductible: water and chargers you keep for passengers, car washes, and the service and booking fees Uber takes from your earnings.
Self-Employed Health Insurance
If you aren’t eligible for coverage through a spouse’s employer plan, you can deduct health, dental, and vision premiums for yourself, your spouse, and your dependents above the line on your federal return.13Internal Revenue Service. Instructions for Form 7206 For a Schedule C filer, the policy can be in either your name or the business name. The deduction lowers federal AGI, which in turn lowers the Illinois base.
Forms Uber Sends and Forms You File
Uber issues a 1099-K if your gross customer payments reached $20,000 and you completed more than 200 transactions in the year.14Internal Revenue Service. IRS Issues FAQs on Form 1099-K Threshold Under the One, Big, Beautiful Bill That form reports gross rider payments, not your take-home. You’ll also get a 1099-NEC if promotions, referral bonuses, and similar non-ride payments totaled $600 or more. You owe tax on all your driving income regardless of whether a 1099 arrives, so work from Uber’s annual tax summary even if you fall under either threshold.15Internal Revenue Service. Gig Economy Tax Center
On the federal side, you report ride income and expenses on Schedule C and compute self-employment tax on Schedule SE. Both attach to Form 1040.3Internal Revenue Service. Self-Employed Individuals Tax Center For Illinois, you file IL-1040. Your federal AGI (which already reflects Schedule C net profit) is the starting number. Illinois has no separate business income schedule. You can file electronically through the MyTax Illinois portal, which handles identity verification and generates a confirmation number.16Illinois Department of Revenue.

Keep a Mileage Log You Can Defend
The single most important record is a contemporaneous mileage log. The IRS wants trips tracked as they happen, not reconstructed from memory in April. A GPS-based tracking app running in the background while you drive is the cleanest approach. Cross-reference the app’s totals against your Uber trip history and fix gaps while they’re still fresh. Beyond mileage, keep receipts for tolls, car washes, phone bills, and anything else you plan to deduct.
Penalties if You Miss a Deadline
Illinois late-payment penalties scale with how late the money arrives:10Illinois Department of Revenue. Pub-103, Penalties and Interest for Illinois Taxes
- 1 to 30 days late: 2% of the unpaid amount.
- More than 30 days late: 10% of the unpaid amount.
- Paid after an audit begins: 15% to 20%, depending on timing.
Illinois also charges simple daily interest at the federal underpayment rate, which resets every six months. The same 2%/10% structure applies to missed quarterly estimated installments.
Filing late is penalized separately: the lesser of $250 or 2% of the tax due. If you still haven’t filed 30 days after a nonfiling notice, add the greater of $250 or 2% of the tax due, capped at $5,000.10Illinois Department of Revenue. Pub-103, Penalties and Interest for Illinois Taxes The reliable way to avoid every one of these numbers is to send your quarterly estimates on time and file by the April deadline, amending later if you need to.
