With the rise of the gig economy and remote work, more people than ever are pursuing side hustles to supplement their income. Whether you’re driving for a ride-share company, freelancing online, selling handmade crafts, or tutoring part-time, any money you earn outside your main job is considered taxable income by the IRS. Properly reporting your side hustle income is essential not only for staying compliant with tax laws but also for maximizing deductions and avoiding penalties.
This blog will walk you through everything you need to know about reporting side hustle income, including what qualifies as a side hustle, how to track earnings and expenses, which tax forms to use, and tips for staying organized throughout the year.
What Is Considered Side Hustle Income?
Side hustle income refers to money earned outside your full-time job, often through self-employment or gig work. It can come from a wide variety of sources, including:
- Freelance services (writing, graphic design, programming, etc.)
- Driving for Uber, Lyft, or DoorDash
- Delivering groceries with Instacart or Shipt
- Selling goods on Etsy, eBay, Amazon, or Facebook Marketplace
- Teaching, coaching, or consulting
- Renting equipment or property (non-Airbnb short-term)
The IRS considers most side hustles as self-employment, and income earned must be reported—even if you don’t receive a 1099 form or the income is paid in cash.
Do You Have to Report All Side Hustle Income?
Yes. All income earned through a side hustle must be reported on your tax return, regardless of the amount or whether you receive a tax form. For example:
- If you earned $100 freelancing and were paid via PayPal or Venmo, you still need to report it.
- If you sell products online and your total revenue exceeds $400, it’s considered self-employment income.
- Even if you did a one-time job and got paid in cash, that income is taxable.
Failure to report side hustle income can lead to audits, penalties, and interest on unpaid taxes.
Common Tax Forms for Side Hustle Income
The forms you use depend on how you earned your income and how much you made:
Form 1099-NEC
If you earned $600 or more from a client or platform in a year, you may receive a Form 1099-NEC. This form reports income earned as an independent contractor. You must report the full amount shown on this form.
Form 1099-K
This form is used by third-party payment processors like PayPal, Venmo, and Square. For 2025, platforms must issue a 1099-K if your total gross payments exceed $600 in the calendar year. Even if you don’t receive a 1099-K, the income must still be reported.
Schedule C (Form 1040)
This is the primary form used by sole proprietors to report business income and expenses. If you’re self-employed or earn money from a side hustle, you’ll typically file a Schedule C with your tax return.
Schedule SE (Self-Employment Tax)
In addition to income tax, self-employed individuals must pay self-employment tax to cover Social Security and Medicare contributions. This is reported using Schedule SE. If your net earnings from self-employment exceed $400, you are subject to this tax.
Tracking Your Income and Expenses
Good record-keeping is crucial for anyone with a side hustle. Not only does it make tax filing easier, but it also allows you to claim deductions that reduce your taxable income. Here’s what you should track:
- Income: All payments received, regardless of source or amount
- Expenses: Any costs related to your hustle, such as supplies, marketing, travel, subscriptions, or software
- Mileage: If you use your personal vehicle for business, track your mileage carefully
- Receipts: Maintain digital or physical copies of receipts and invoices
Using accounting software like QuickBooks, Wave, or a dedicated spreadsheet can simplify this process.
What Deductions Can You Claim?
If your side hustle qualifies as a business (rather than a hobby), you can deduct ordinary and necessary business expenses. Some common deductions include:
- Home office expenses
- Internet and phone usage
- Office supplies and equipment
- Marketing and advertising costs
- Travel and transportation (including mileage)
- Professional fees (legal, accounting, software)
- Business-related education and certifications
The IRS requires that all expenses be directly related to your business and properly documented.
Hobby vs. Business: Why Classification Matters
The IRS distinguishes between hobbies and businesses. If your side activity is a hobby, you can’t deduct expenses in excess of income. However, if it’s a business, you can deduct losses against other income. The IRS considers a variety of factors to make this determination, including:
- Profit motive
- Consistency of operations
- Dependence on income for livelihood
- Effort put into the activity
If your side hustle turns a profit in three out of five consecutive years, the IRS is more likely to consider it a business.
Do You Need to Pay Estimated Taxes?
Yes, possibly. Unlike regular employment, side hustle income typically has no tax withheld. If you expect to owe $1,000 or more in taxes for the year (after withholding and credits), the IRS requires you to make quarterly estimated payments using Form 1040-ES.
Estimated payments are due on:
- April 15
- June 15
- September 15
- January 15 of the following year
Failure to make timely payments may result in penalties and interest.
Tips for Staying Compliant and Efficient
- Open a separate bank account for your side hustle
- Set aside 25–30% of your income for taxes
- Use apps to track mileage, time, and receipts
- Review your finances quarterly to assess profitability and tax obligations
- Hire a tax professional if your side hustle grows in complexity
How Side Hustle Income Affects Your Refund
Side hustle income can either increase or reduce your refund, depending on how much tax you owe and what deductions you claim. If you haven’t made estimated payments and owe self-employment tax, your refund could be reduced. Conversely, tracking expenses and maximizing deductions can reduce your tax liability and increase your refund potential.
What Happens If You Don’t Report Side Hustle Income?
Failing to report side income can lead to serious consequences:
- IRS audits
- Accuracy-related penalties
- Interest on unpaid taxes
- Criminal charges for intentional tax evasion in extreme cases
Many digital platforms now report income to the IRS through 1099-Ks or 1099-NECs, so it’s easier than ever for the IRS to detect unreported earnings.
Conclusion: Don’t Overlook the Importance of Tax Reporting
Running a side hustle can be incredibly rewarding—both financially and personally. However, with that freedom comes the responsibility of proper tax reporting. By keeping good records, understanding your tax obligations, and filing accurately with the correct forms, you can avoid costly mistakes and maximize your earnings. Whether your side hustle is a weekend gig or a pathway to full-time entrepreneurship, treating it like a business from the start ensures long-term success and peace of mind.
