When does a side hustle need to be reported on taxes in 2025?

All side hustle income is taxable regardless of the amount. There is no minimum threshold for reporting self-employment income. Even if you earned $50 from a one-time freelance gig, it is technically taxable.

When you owe self-employment tax: If your net self-employment income is $400 or more for the year, you must file a tax return and pay self-employment tax (15.3%). This applies even if your total income is below the standard filing threshold.

1099 forms vs. reporting obligations: You may receive a 1099-NEC (for freelance work, $600+) or 1099-K (for payment platform transactions, $5,000+ for 2024). However, not receiving a 1099 does not mean the income is tax-free. Cash payments, Zelle transfers, and small payments below the 1099 thresholds are all reportable.

How to track expenses: Keep a dedicated notebook, spreadsheet, or app to log all income and expenses related to your side hustle. Deductible expenses include supplies, equipment, mileage, software, advertising, and professional services. The more organized you are during the year, the easier (and cheaper) tax time will be.

Quarterly estimated taxes: If you expect to owe $1,000 or more in taxes (including SE tax) when you file, make quarterly estimated payments using Form 1040-ES. Alternatively, if you also have a W-2 job, you can increase withholding on your W-4 to cover the additional tax. This is often simpler than making quarterly payments.
