The gig economy turned millions of Americans into small-business owners overnight — often without realizing it. Whether you drive, deliver, sell crafts, or freelance on the side, the IRS sees you as self-employed. That brings a tax bill most W-2 workers never face, but also deductions they can't take. Here's how to handle it.
You're a business now
The moment you earn money from gig work, you're running a business in the eyes of the IRS. You report the income (and expenses) on Schedule C, and your net profit is subject to two taxes: ordinary income tax and the 15.3% self-employment tax that covers both halves of Social Security and Medicare. That second tax is the surprise that catches new gig workers.
The forms: 1099-K and 1099-NEC
- 1099-NEC — reports nonemployee compensation of $600 or more, common for freelance and contractor work.
- 1099-K — reports payments processed through platforms and apps (rideshare, delivery, marketplaces, payment apps). The reporting threshold has dropped sharply, so many more casual sellers and part-time gig workers now receive one.
The deductions that cut your bill
Here's the upside of being self-employed: you deduct business expenses, and every dollar of legitimate expense lowers both your income tax and your self-employment tax. Common gig deductions:
- Vehicle — for drivers and delivery workers, usually the biggest one: the standard mileage rate (72.5¢/mile for 2026) or actual costs. See the vehicle deduction guide.
- Phone and data — the business-use percentage of your cell plan.
- Supplies and equipment — delivery bags, crafting materials, a laptop, a camera.
- Platform and payment fees — Etsy, Uber, PayPal, and marketplace commissions.
- Home office — a portion of rent and utilities if you have a dedicated workspace.
Track these all year with a separate account and a mileage app — at tax time, good records can easily save a driver several thousand dollars.
Set aside money and pay quarterly
Because no employer withholds tax from gig income, the IRS expects quarterly estimated payments if you'll owe $1,000 or more. The simplest discipline: move 25–30% of each payout into a separate savings account and pay your estimates from it. Skip this and you risk both a large April bill and an underpayment penalty. The self-employment tax calculator turns your expected profit into the tax you'll owe.
Business vs. hobby
If you pursue the activity regularly and intend to profit, it's a business — and you can deduct expenses. If it's a genuine hobby, you must still report the income but generally can't deduct expenses against it. Most consistent gig work clearly qualifies as a business.
When gig income grows
As a side hustle becomes serious income, two moves matter: open a SEP-IRA or Solo 401(k) to shelter profit for retirement (and cut taxes), and once profit is consistently high, ask a professional whether an S-corp election would reduce self-employment tax. Both are covered in the self-employment guide.
Juggling multiple gigs — and mixing W-2 and gig work
Many gig workers have several income streams at once: a W-2 job plus rideshare, or two or three platforms. A few rules keep it manageable. Combine all your self-employment income and expenses on a single Schedule C (or one per distinct business). If you also hold a W-2 job, you can raise that job's withholding on your W-4 to cover the gig tax — often simpler than quarterly payments. And remember the Social Security wage base applies across all your earnings combined, so high earners may stop owing the 6.2% Social Security portion partway through the year.
Key takeaways
- All gig income is taxable, with or without a 1099.
- You owe 15.3% self-employment tax on net profit, plus income tax.
- Deduct mileage, phone, supplies, fees, and home office to cut both taxes.
- Set aside 25–30% and pay quarterly estimated taxes.
- Track everything — records are what protect your deductions.
