Self-Employed & Gig Income: Every Guide, In One Place

1099 income, quarterly estimates, and self-employment tax trip up more taxpayers than anything else. These guides are written for freelancers, contractors, and gig workers.

If your net earnings from self-employment were $400 or more, you owe self-employment tax and must file Schedule SE with Form 1040. Self-employment tax is 15.3%: 12.4% for social security and 2.9% for Medicare. Gig income is taxable even if it was paid in cash and never reported on a 1099-K, 1099-NEC or 1099-MISC. As a self-employed individual, you may have to file estimated taxes quarterly.

• The self-employment tax rate is 15.3%, made up of 12.4% for social security and 2.9% for Medicare hospital insurance.

What do self-employed and gig workers actually owe?

Self-employment tax is a tax consisting of Social Security and Medicare taxes primarily for individuals who work for themselves. It is similar to the Social Security and Medicare taxes withheld from the pay of most wage earners, except that no employer calculates it for you. You figure it yourself using Schedule SE, Self-Employment Tax, attached to Form 1040.

The rate is 15.3%: 12.4% for social security (old-age, survivors, and disability insurance) and 2.9% for Medicare (hospital insurance). For 2024, the first $168,600 of your combined wages, tips, and net earnings is subject to the social security part. The 2.9% Medicare part applies to all of your net earnings. If your wages, compensation, or self-employment income (together with your spouse's if you file jointly) exceed the threshold for your filing status, you are also liable for an additional 0.9% Medicare Tax.

If you work as a sole proprietor or independent contractor, you generally use Schedule C, Profit or Loss from Business, to figure net earnings, then Schedule SE to figure the tax. These rules apply no matter how old you are and even if you are already receiving Social Security or Medicare.

When do I have to pay tax on gig or freelance income?

Nobody withholds tax from a gig payment, so the IRS collects it during the year instead. As a self-employed individual, you may have to file estimated taxes quarterly, and you can use those estimated tax payments to pay your self-employment tax. Publication 505, Tax Withholding and Estimated Tax, covers how to work out what to send in.

To pay self-employment tax at all, you must have a Social Security number (SSN) or an individual taxpayer identification number (ITIN). If you never had an SSN, you apply using Form SS-5, Application for a Social Security Card, available at any Social Security office or by calling 800-772-1213. The IRS will issue an ITIN if you are a nonresident or resident alien who does not have and is not eligible to get an SSN; you apply on Form W-7.

Falling behind on estimated payments is a common reason self-employed people end up with a balance due at filing time. If that has already happened, the IRS offers payment options through Your Online Account and payment plan (installment agreement) channels, and the sooner you address the balance the fewer collection steps you have to unwind.

What if I never got a 1099 for my gig work?

You must report income earned from the gig economy on a tax return even if it was not reported on an information return form like a Form 1099-K, 1099-MISC, 1099-NEC, W-2 or other income statement. The same is true if the work was part-time, temporary or side work, and if you were paid in cash, property, goods, or virtual currency.

Gig work is activity you do to earn income, often through an app or website, such as:

• Driving a car for booked rides or deliveries
• Renting out property or part of it
• Running errands or completing tasks
• Selling goods online or renting equipment
• Providing creative or professional services, or other temporary, on-demand or freelance work

Because platforms do not always issue a form, your own records matter. Keeping records of what you earned and what you spent lets you deduct expenses and figure net earnings correctly on Schedule C, which in turn drives the self-employment tax you report on Schedule SE. If you file Form 1040 with Schedule C, you may also be eligible to claim the Earned Income Tax Credit.

Frequently asked questions

Do I owe self-employment tax if gig work is only a side job?

Yes, if your net earnings from self-employment were $400 or more. The IRS says you must report income earned from the gig economy on a tax return even when it comes from part-time, temporary or side work, and even when it is not reported on a Form 1099-K, 1099-MISC, 1099-NEC or W-2. Payment in cash, property, goods or virtual currency still counts.

How do I pay self-employment tax during the year?

As a self-employed individual, you may have to file estimated taxes quarterly, and you can use those estimated tax payments to pay your self-employment tax. Publication 505, Tax Withholding and Estimated Tax, explains the calculation in more detail. You also need a Social Security number or an individual taxpayer identification number before you can pay self-employment tax at all.

What if my wages already reached the social security wage limit?

If your wages and tips are subject to social security tax or railroad retirement tier 1 tax and total at least $168,600, you do not pay the 12.4% social security part of the self-employment tax on your net earnings. The 2.9% Medicare part of the self-employment tax still applies. An additional 0.9% Medicare Tax can also apply above the threshold for your filing status.

Can I deduct any part of my self-employment tax?

You can deduct the employer-equivalent portion of your self-employment tax when figuring your adjusted gross income. This deduction only affects your income tax; it does not reduce your net earnings from self-employment or the self-employment tax itself. Self-employed individuals are also allowed a deduction for the cost of health insurance, which is taken into account when calculating net earnings from self-employment.
