As the gig economy continues to grow, more individuals are earning income through freelance work, side gigs, and self-employment. While this offers flexibility and independence, it also introduces new responsibilities—especially at tax time. Filing Form 1040 correctly when you have freelance or gig income is essential to staying compliant and avoiding penalties.
Whether you’re a U.S. individual taxpayer or a CPA managing multiple freelancer clients, understanding how to handle self-employment income on Form 1040 is crucial.

What Counts as Freelance or Gig Income?
Freelance or gig income includes earnings from:
- Freelance writing, design, programming, consulting, etc.
- Driving for Uber, Lyft, or delivery apps
- Renting out rooms via Airbnb
- Online marketplaces like Fiverr, Upwork, or Etsy
- Contract work where you receive a 1099-NEC
If you earn $400 or more from self-employment, you must file a tax return and pay self-employment tax in addition to income tax.
Which Forms to File With Your 1040
When you’re self-employed, your freelance or gig income must be reported on Schedule C (Profit or Loss from Business), which attaches to Form 1040. If you made more than $400 in net earnings, you’ll also need to file Schedule SE (Self-Employment Tax).
- Form 1040: The main individual income tax return
- Schedule C: Reports income and expenses for your business
- Schedule SE: Calculates self-employment tax (Social Security and Medicare)
- Form 1099-NEC: Received from clients who paid you $600 or more
Step-by-Step Guide to Filing Your Taxes
1. Gather Your Income Records
Collect all Forms 1099-NEC, PayPal earnings, cash payments, and receipts for your freelance or gig work. If you didn’t receive a 1099, you’re still required to report your income.
2. Track Your Business Expenses
Legitimate business expenses reduce your taxable income. Examples include:
- Internet and phone bills
- Office supplies
- Advertising and software tools
- Home office deduction
- Mileage or vehicle use
Use accounting software or spreadsheets to log expenses throughout the year.
3. Fill Out Schedule C
Use Schedule C to calculate your net profit or loss. You’ll list total income, subtract deductible business expenses, and determine the net income that flows into your Form 1040.
4. Fill Out Schedule SE
This form calculates your self-employment tax. For 2024–2025, the self-employment tax rate remains at 15.3% on net earnings. You can deduct half of your SE tax as an adjustment to income on Form 1040.
5. Complete Form 1040
Include your business income, adjustments, and other income sources. Don’t forget to claim applicable deductions and tax credits such as:
- Earned Income Tax Credit (EITC)
- Child Tax Credit
- Health insurance premium deductions if self-employed
6. Submit Your Return and Pay Estimated Taxes
If you expect to owe $1,000 or more in taxes, you must pay estimated taxes quarterly using Form 1040-ES. This prevents underpayment penalties.
