Side Hustle and 1099 Taxes in 2026: What You Owe and How to Prepare
The rise of gig work, freelancing, and online income has made 1099 tax situations more common than ever. Whether you drive for a rideshare service, sell on Etsy, take on freelance clients, or deliver food on weekends, income from side activities is taxable and must be reported on your federal return. For the 2026 filing season covering the 2025 tax year, this guide explains what you owe, how to calculate your tax liability, and what you can do to reduce it.[1][2]
All Side Hustle Income Is Taxable
Income from side gigs is taxable regardless of the amount and regardless of whether you receive a formal tax document. Payers who paid you $600 or more during 2025 are required to send you Form 1099-NEC by January 31, 2026. But even if you earned less than $600 from a single client, that income is still taxable and must be included on your return.[1][3]
Payment app income, cash payments for services, income from online marketplaces, and barter income are all taxable. The IRS receives copies of 1099 forms filed on your behalf, and any discrepancy between what a payer reports and what you report on your return will draw attention.[2]
Self-Employment Tax: The 15.3 Percent Factor
When you work as an employee, your employer withholds payroll taxes for Social Security and Medicare and pays the employer's matching share. When you are self-employed, you pay both sides yourself. The self-employment tax rate is 15.3 percent of net earnings (12.4 percent for Social Security up to the wage base of $176,100 for 2025 and 2.9 percent for Medicare on all net earnings).[1][2]
This means that a side hustle generating $20,000 in net profit carries roughly $2,826 in self-employment tax on top of whatever income tax applies to that $20,000 at your marginal rate.[3]
The Importance of Deducting Business Expenses
You pay self-employment tax on your net earnings, meaning your gross income minus allowable business expenses. Claiming every legitimate expense reduces both your income tax and your self-employment tax. Common deductible side hustle expenses include:[1][2]
Mileage for business driving at the 2025 IRS standard rate of 70 cents per mile, with a mileage log as documentation
Tools, supplies, and materials used for your work
Platform fees charged by apps or marketplaces
Portion of phone and internet bills attributable to business use
Home office expenses if you have a dedicated workspace
Advertising and marketing costs
Professional fees and subscriptions
Quarterly Estimated Payments
If you expect to owe at least $1,000 in federal taxes from your side hustle income in 2025, you are required to make quarterly estimated tax payments throughout the year. For 2025 income, the payment deadlines are April 15, June 16, and September 15, 2025, and January 15, 2026. Failing to make adequate estimated payments results in an underpayment penalty.[2][3]
A simple approach to estimating your payment is to set aside 25 to 30 percent of your net self-employment income in a separate savings account and pay it in quarterly installments. This rate roughly covers self-employment tax plus income tax for most middle-income earners.[1]
1099-K Reporting: What Changed
Form 1099-K is issued by payment platforms when you receive payments above certain thresholds. The IRS has been in the process of lowering the threshold from $20,000 and 200 transactions to $5,000 as a transitional measure, with the eventual statutory threshold of $600. For 2025, more side hustle workers and online sellers may receive 1099-K forms than in prior years. Check your payment platform or marketplace for your expected form before filing.[2][3]
Tracking Income and Expenses Year-Round
Accurate records are essential for side hustle taxes. Recommended practices include:[1][2]
Keeping business income and expenses in a separate bank account
Using accounting software or a simple spreadsheet to track transactions monthly
Saving receipts, invoices, and payment confirmations for all business expenses
Maintaining a mileage log if you drive for business
Noting the business purpose of each expense at the time it occurs
Schedule C: Reporting Your Business
Most side hustle income is reported on Schedule C of Form 1040, which calculates net profit or loss from self-employment. Net profit from Schedule C flows to your Form 1040 as taxable income and is also the basis for your self-employment tax calculation on Schedule SE.[1][3]
Conclusion
Side hustle income carries real tax obligations, but careful expense tracking and timely estimated payments keep the process manageable. The key is understanding that you owe both income tax and self-employment tax on net earnings, that deductions reduce both, and that paying quarterly prevents a large and potentially penalized balance at filing time. Free resources from the IRS, including the self-employed tax center at IRS.gov, can help you navigate the specifics of your situation.[1][2][3]
