Side hustle taxes catch many people off guard in their first year: the income is taxable from the first dollar, whether or not a platform sends you a form, and no employer is withholding tax for you.

Driving for a rideshare app, reselling sneakers, designing logos on weekends, walking dogs or renting out a spare room all count. The IRS describes the gig economy as activity where people earn income providing on-demand work, services or goods, often through an app or website. Its rule is simple: gig income is taxable, and you must report it even if it is part-time, temporary or side work, even if you were paid in cash, property, goods or virtual currency, and even if no information return was issued.

The good news is that a side business is also a business for tax purposes. That means you can deduct real expenses, and a few habits from day one make tax season routine instead of stressful. This guide covers the rules as of November 2026, including the reporting changes from the One, Big, Beautiful Bill Act signed in July 2025.

What changed for 2026: fewer forms, same tax

Two thresholds moved, and both mean you may receive fewer forms. Neither changes what you owe.

• Form 1099-K (payment apps and online marketplaces). After the One, Big, Beautiful Bill, the IRS says payment apps and marketplaces must report payments for goods or services only when they exceed $20,000 in more than 200 transactions in a year. The law reinstated the threshold in effect before 2021, so the much-discussed $600 rule never took effect. Payments you take by credit or debit card are different: the IRS says there is no minimum for card transactions.
• Form 1099-NEC (clients who pay you for services). Businesses report payments to non-employees of $2,000 or more for payments made after December 31, 2025, up from $600. A client who pays you $1,500 for a website in 2026 may send no form at all.

Gifts and shared bills are not income

Money a friend sends to split rent or dinner, or a birthday gift through a payment app, is not taxable income and should not be reported on a 1099-K. The IRS suggests marking those payments as personal or non-business in the app when you can. If you sell personal items, such as old furniture, income from items sold at a gain must be reported.

Hobby or business?

The IRS says a key feature of a business is that you do the activity to make a profit; a hobby is done mainly for sport or recreation. The distinction matters because a business reports income and deducts its ordinary and necessary expenses on Schedule C, while hobby income is still taxable but does not get the same treatment. If you advertise, keep books, set prices to earn money and track profit, you are acting like a business. When the line is unclear, ask a tax professional before you file.

The two taxes on side income

Side hustle profit is taxed twice over, in a sense: once as income, and once for Social Security and Medicare. An employer pays half of those payroll taxes for its employees; when you work for yourself, you pay both halves.

• Income tax: your side profit is added to your wages and other income and taxed at your federal bracket, then again by California.
• Self-employment tax: you owe it, and file Schedule SE, when net earnings from self-employment are $400 or more.
• A partial offset: the IRS lets you deduct the employer-equivalent portion of your self-employment tax when figuring adjusted gross income. It lowers income tax, not the self-employment tax itself.
• High earners: an additional 0.9% Medicare tax applies above $200,000 for single filers and $250,000 for married couples filing jointly.

If you also have a W-2 job, your wages count toward the $184,500 Social Security limit first, so a high-salary employee may owe only the 2.9% Medicare part on side profit above that line.

Deductions that lower side hustle taxes

You pay tax on profit, not on gross receipts. Every legitimate business expense you record reduces both income tax and self-employment tax. The most common ones for side businesses:

The IRS raised the business mileage rate in the middle of 2026, so drivers should split their log at June 30. A delivery driver who logs 4,000 business miles in the first half and 4,000 in the second half would deduct $2,900 plus $3,040, or $5,940, using the standard rate.

Paying as you go: estimated taxes

No one withholds tax from side income, so the IRS expects you to pay during the year. You generally must make estimated payments if you expect to owe $1,000 or more when you file. California applies a lower threshold of $500 for most filers and wants the money on a different schedule.

If you have a day job, there is an easier route: ask your employer to withhold more from each paycheck by filing a new Form W-4. Withholding is treated as paid evenly through the year, which can cover the tax on side income without quarterly vouchers.

California and Sacramento extras

• Local business license: many cities and Sacramento County require a business operations tax certificate even for home-based work; see our Sacramento business license guide.
• Seller’s permit: if you sell taxable goods in California, the California Department of Tax and Fee Administration (CDTFA) may require a seller’s permit and sales tax returns. Some marketplaces collect sales tax for you; check before you register.
• State taxes on the business: an LLC owes California’s $800 annual tax even in a slow year; our California small business taxes guide explains when a side hustle should and should not become an LLC.

Common mistakes

• Reporting only what is on a 1099. All income counts, including cash and payments under the new thresholds.
• Ignoring self-employment tax. The 15.3% applies on top of income tax once net earnings reach $400.
• Mixing personal and business money. It hides deductions and makes an audit harder to answer.
• Using one mileage rate for all of 2026. The IRS rate changed on July 1.
• Skipping estimated payments. A big April bill can come with an underpayment penalty.

Key terms

• Form 1099-K: a report of payments you received through payment apps, marketplaces or card processors.
• Form 1099-NEC: a report from a client that paid you $2,000 or more for services in 2026.
• Schedule C: the form that reports a sole proprietor’s business income and expenses.
• Schedule SE: the form that figures self-employment tax.
• Standard mileage rate: the IRS rate per business mile you can deduct instead of actual car costs.

The bottom line: side hustle taxes are manageable when you treat the side hustle like a business from the first sale. Keep income and expenses in their own account, log miles and receipts, set money aside from every payout, and file Schedule C and Schedule SE. Fewer 1099 forms in 2026 change the paperwork, not the tax.
