Gig Work Taxes: 1099 Forms, Quarterly Payments, Mileage Deduction

You're an "independent contractor," not an employee — what that actually means

Most rideshare and delivery platforms classify drivers as independent contractors, not employees, so nothing is automatically withheld from your payouts for income tax or Social Security, unlike a W-2 job. Three practical consequences follow:

• You calculate and pay your own tax — not Uber, not DoorDash.
• You pay self-employment tax in addition to regular income tax, because you're considered your own employer.
• You can deduct business expenses (fuel, maintenance, phone, mileage) before your taxable net profit is calculated — something a W-2 employee usually can't do.

1099-K vs. 1099-NEC: which form will you get?

These two get mixed up constantly. Per the IRS:

The most important point in the IRS's own guidance: you must report all your self-employment income regardless of whether you receive a 1099-K or 1099-NEC. If you were paid in cash or through an app that didn't issue a form because you were under the threshold, that doesn't excuse you from reporting it.

The 15.3% self-employment tax isn't a random extra charge

Per the IRS, once your net self-employment earnings hit $400 or more in a year, you owe self-employment tax at 15.3%, split into 12.4% for Social Security and 2.9% for Medicare. This replaces the combined share an employee and employer each pay in a regular W-2 job (where that percentage is split roughly between them); in self-employment, you're both sides.

This tax is calculated on your net profit (income minus allowed deductions), not your gross platform payout. You can also deduct half of your self-employment tax from your regular taxable income — a detail your filing software usually handles automatically. If your combined income (wages plus self-employment) crosses certain thresholds that vary by filing status, an additional 0.9% Medicare tax applies, per IRS.gov.

Quarterly estimated payments: why and when

Since nobody withholds your tax automatically, the IRS requires many self-employed people to pay in four installments through the year instead of waiting for the annual filing deadline. Per IRS.gov, you owe quarterly payments if you expect to owe $1,000 or more after subtracting withholding, and your withholding and credits don't cover 90% of this year's tax or 100% of last year's tax (110% if your prior-year adjusted gross income exceeded $150,000).

If any of these falls on a weekend or holiday, it moves to the next business day. These payments are made with Form 1040-ES, and you can pay electronically through IRS Direct Pay or EFTPS.

The mileage deduction: a gig driver's biggest legitimate write-off

The IRS publishes a standard mileage rate for business use instead of requiring you to track every fuel and maintenance receipt separately. For 2026, two rates apply because of a rare mid-year adjustment:

• 72.5 cents per mile for January 1 through June 30, 2026.
• 76 cents per mile for July 1 through December 31, 2026, after the IRS's exceptional mid-year adjustment in response to rising fuel prices.

Apply the correct rate to the miles driven in each period, not one rate for the whole year. This rate roughly bundles fuel, maintenance, and depreciation, so don't separately deduct a fuel receipt if you're using the standard mileage method; choose either the standard rate or documented actual expenses, not both for the same car in the same year.

Other expenses you can deduct

• The business-use share of your phone and data plan if you use it for apps and navigation.
• Direct work supplies like a phone mount, delivery bags, or snacks/water you provide Uber riders if you use the actual-expenses method.
• Platform fees and payment card processing fees.
• Part of your car insurance if you choose the actual-expenses method instead of the standard rate; see our car insurance guide to understand the difference between personal and commercial coverage.

A worked example: what do you actually pay?

Say Karim drives for DoorDash and grossed $42,000 across apps this year, driving 18,000 business miles (roughly split evenly across the two rate periods). Mileage deduction math: 9,000 miles × 72.5 cents = $6,525, plus 9,000 miles × 76 cents = $6,840, for a combined mileage deduction of about $13,365 — before any other expenses like phone or platform fees. Add $1,500 in other documented expenses, and his taxable net profit is roughly 42,000 − 13,365 − 1,500 = $27,135. Self-employment tax on that net figure runs 15.3% (about $4,151), plus regular federal income tax at his bracket, and possibly a state tax if his state charges one. This is a rough illustration only, not an official calculation — use IRS-approved filing software or a preparer for your exact numbers.

Record keeping: the habit that saves the most money

The costliest mistake for gig drivers usually isn't a missed payment — it's having no documented record if you're ever reviewed. A reasonable minimum:

• A daily mileage log with date, distance, and purpose, either through an independent tracking app or a paper log updated right after each trip.
• Every expense receipt (fuel, maintenance, accessories) if you use the actual-expenses method, kept as a photo or original, not just a number you remember.
• A separate business bank account that makes it easy to reconcile the income reported on a 1099-K or 1099-NEC against what you actually received.
• A copy of every 1099 form you get from each platform, even if the number looks familiar.

Many accountants recommend keeping these records for at least 3 years after you file, since that's the common window for a standard IRS review in most cases.

Common mistakes new gig drivers make

• Waiting for the annual filing deadline instead of paying quarterly, letting an underpayment penalty build up.
• Not logging mileage daily and relying on a rough year-end estimate.
• Combining the standard rate and actual expenses for the same car in the same year, which isn't allowed.
• Assuming no 1099-K means no income to report.
• Forgetting that personal car insurance may not cover accidents during commercial work without added commercial coverage.
• Not keeping a separate bank account for work income and expenses, making it harder to track everything at filing time.

What to do next

1. Start a mileage tracking app today if you don't already have one, and log every business trip from now on.
2. Calculate your next quarterly payment using Form 1040-ES before the upcoming deadline.
3. Open a separate bank account for work income and expenses.
4. Get the broader picture of the US tax system in our first tax return guide, and if you're considering forming a business entity later, see our LLC formation guide.
