Side Hustle Taxes: What You Need to Know
Overview
This page is an informational summary only. It reflects general federal tax information for tax year 2025 (returns filed in 2026) drawn from IRS publications. Tax rules change; confirm current requirements at irs.gov or with a qualified tax professional before filing.
Side hustle income is taxable. Whether you drive for a rideshare app, freelance on weekends, sell handmade goods online, or do odd jobs for neighbors, the income counts as taxable income under federal law — even when it is paid in cash, through a payment app, or without any tax form arriving in the mail. Once net self-employment earnings reach $400, self-employment (SE) tax applies on top of regular income tax, and you report business activity on Schedule C.
Is side hustle income taxable?
Yes. Federal tax law taxes income from all sources unless a specific exclusion applies. A side hustle — regardless of how part-time it is or how the payment arrives — produces taxable income.
The most common misconception is that income is only taxable if a payer sends a Form 1099-NEC or 1099-K. That is not correct. The obligation to report and pay tax on income exists independently of whether you receive a form. If a client pays you $200 cash to paint a fence, or a customer pays through Venmo for a piece of furniture you built, that income is reportable on your federal return.
The IRS Gig Economy Tax Center consolidates guidance for workers earning income outside traditional employment. It covers rideshare drivers, freelancers, online sellers, and anyone exchanging services or goods for payment.

When do I owe self-employment tax?
Self-employment (SE) tax applies when net self-employment earnings — gross income from the activity minus allowable business expenses — reach $400 or more for the year. Net earnings below that threshold are still includible as income but do not trigger SE tax.
The SE tax rate is 15.3 percent: 12.4 percent for Social Security and 2.9 percent for Medicare. This rate applies because self-employed workers pay both the employee and employer share of these payroll taxes. (Employees at traditional jobs see only 7.65 percent withheld from their paychecks; their employer remits the other 7.65 percent separately.)
SE tax is calculated on Schedule SE and added to the income tax shown on Form 1040. You may deduct one-half of the SE tax as an adjustment to income when computing your adjusted gross income — this mirrors the deduction that employers receive for their share of payroll taxes.
Note that SE tax and income tax are separate obligations. A side hustle generating $400 net could owe SE tax even if total income is too low to generate income tax liability.
What tax forms apply to a side hustle?
Several federal forms come into play for self-employed workers and gig earners. The table below summarizes the primary ones.
| Form | Purpose | Who files or receives it |
|---|---|---|
| Schedule C (Form 1040) | Report profit or loss from a sole proprietorship or single-member LLC treated as a sole proprietor | You file; attached to Form 1040 |
| Schedule SE (Form 1040) | Calculate the self-employment tax owed on net earnings from Schedule C | You file; attached to Form 1040 |
| Form 1099-NEC | Reports nonemployee compensation paid to you by a client or business | Client or payer sends to you when payments generally reach $600 or more (confirm current threshold at irs.gov) |
| Form 1099-K | Reports payments processed through third-party payment networks and marketplaces | Platform or payment processor sends to you; threshold has changed by recent legislation — confirm current rules at irs.gov |
Schedule C
Schedule C is the core reporting document for most self-employed individuals and sole proprietors. You list gross receipts, subtract allowable business expenses, and arrive at net profit or loss. Net profit flows to Form 1040 as income and also to Schedule SE for SE tax computation. The IRS provides detailed instructions at its Schedule C resource page.
Form 1099-NEC
A client that pays $600 or more for services during the year generally issues a Form 1099-NEC (confirm the current threshold at irs.gov, as thresholds can change). Receiving a 1099-NEC does not create the tax obligation — the obligation exists because of the income itself. Not receiving one does not eliminate the obligation. Report the income on Schedule C regardless of whether a form arrives.
Form 1099-K
Payment apps and online marketplaces report transactions on Form 1099-K. The reporting threshold for this form has been the subject of recent legislative changes and IRS transitions. Rather than state a specific dollar amount that may be outdated, review the current rules directly at the IRS understanding your Form 1099-K page. As with 1099-NEC, the absence of a 1099-K does not eliminate your obligation to report income received through these platforms.

Is my side gig a business or a hobby?
The distinction matters because it affects how expenses are treated. An activity carried on for profit is treated as a business; one not carried on for profit may be treated as a hobby.
- Business: Income is reported on Schedule C. Ordinary and necessary business expenses are deductible on Schedule C, reducing taxable net profit.
- Hobby: Income is still taxable and reportable. However, hobby expenses are generally not deductible under current law for federal income tax purposes.
The IRS does not apply a single bright-line test. It weighs a range of factors to determine whether an activity is profit-motivated, including:
- Whether the activity is carried on in a businesslike manner, with records and separate accounts
- The time and effort put into the activity
- Whether the taxpayer depends on the income for a livelihood
- Whether losses are due to circumstances beyond control or are typical of a startup period
- Whether the taxpayer has changed methods of operation to improve profitability
- The history of income and losses across years
- Whether the taxpayer has made a profit in similar activities in the past
There is a general presumption that an activity is for profit if it produces net profit in at least three of the five consecutive tax years ending with the current year (two of seven years for activities involving horses). This is a presumption that can be rebutted, not an automatic rule. A tax professional can help evaluate the facts.
If you are uncertain whether your activity is a business or hobby, keeping thorough records of your profit motive — business plans, marketing efforts, time logs, and financial records — supports a business classification if the IRS ever inquires.
Do I need to pay quarterly estimated taxes?
Employees in traditional jobs have income tax withheld from each paycheck throughout the year. Self-employed workers generally do not have withholding, so the federal tax system requires them to prepay taxes in four installments called estimated tax payments.
The general rule: if you expect to owe $1,000 or more in federal taxes after accounting for any withholding and credits, estimated payments are typically required. Failing to pay enough during the year can result in an underpayment penalty — even if you pay the full balance when you file.
For a side-hustle worker who also has a W-2 day job, one alternative to making separate estimated payments is increasing the withholding on the W-2 job. If the additional withholding from the day job covers the tax liability from the side activity, separate quarterly payments may not be necessary. The IRS withholding estimator at irs.gov can help you determine whether current withholding is sufficient.
Estimated tax due dates for most taxpayers generally fall in April, June, September, and January of the following year. Confirm the specific dates for the current year on the IRS estimated taxes page.

Keeping records for your side hustle
Good recordkeeping is not optional — it is the foundation of an accurate return and your primary protection if the IRS asks questions. At minimum, maintain records of:
- All income received, including cash and app payments not covered by a 1099
- Receipts and invoices for business expenses you intend to deduct
- Mileage logs if you use a vehicle for business purposes
- Bank and payment-app statements showing business transactions
- Any contracts or written agreements with clients
Business expenses must be both ordinary (common and accepted in your trade or business) and necessary (helpful and appropriate). Personal expenses are not deductible, and mixed-use items — a phone used for both personal and business calls, for example — require an allocation based on actual use.
Keep records for at least three years from the date you filed the return, which is the general statute of limitations for the IRS to assess additional tax. Longer retention may be appropriate in certain circumstances.

Frequently asked questions
I did not get a 1099 — do I still have to report my side hustle income?
Yes. The obligation to report income comes from receiving it, not from receiving a form. If a client paid you under the 1099-NEC threshold, paid you in cash, or paid through an app that did not issue a 1099-K, the income is still taxable. Report all income on Schedule C regardless of whether any form was issued.
I only earned $300 from my side gig. Do I owe anything?
The $300 in income is taxable and must be included in gross income on your return, subject to your overall filing obligation thresholds. Self-employment tax (15.3 percent of net earnings) applies once net self-employment income reaches $400 for the year. If net earnings from your side work are below $400, SE tax does not apply — but the income itself may still affect income tax depending on your total income and filing status. Confirm your specific situation with a qualified tax professional.
Can I deduct the expenses from my side hustle?
If the activity qualifies as a business rather than a hobby, ordinary and necessary expenses directly related to the business are generally deductible on Schedule C. Examples include materials, software subscriptions used for the business, home office space used regularly and exclusively for the business, and business-related travel. Personal expenses are not deductible. Keep receipts and records for every expense you claim.
What if my side hustle loses money?
A net loss on Schedule C generally offsets other income on Form 1040, reducing overall taxable income — provided the activity is treated as a business rather than a hobby. Repeated losses across multiple years can trigger IRS scrutiny about whether the activity is profit-motivated. Documentation of your profit motive and businesslike operation is important if losses recur.
