Self employment tax basics for young adults

Short answer

Self-employment tax is a special tax self-employed young adults pay to cover Social Security and Medicare benefits. It applies to your net earnings from gigs, freelance work, or small businesses at a rate of about 15.3%. Understanding how to calculate, report, and pay it helps avoid surprises and keeps you on track financially.

What is self-employment tax in plain words?

Self-employment tax is the money you pay to fund Social Security and Medicare when you work for yourself instead of a company. If you have a regular job, your employer takes these taxes out of your paycheck automatically. But if you earn money independently—like tutoring, freelancing, or running an online shop—you are responsible for paying this tax yourself.

This tax covers benefits you could get later in life, such as retirement income and medical care through Medicare. For young adults aged 18 to 24 who start earning money on their own, knowing about self-employment tax helps you stay compliant with tax laws and build your future benefits. It’s separate from income tax, meaning you need to pay both if you have taxable income.

Even if your earnings are small, self-employment tax rules apply once your net income passes a certain amount. For example, if you earn $500 net from freelance work, you’ll generally owe self-employment tax on that amount. Missing this can lead to owing money plus penalties later.

How does self-employment tax work with an example?

Self-employment tax applies to your net earnings from self-employment, which means the money you make after subtracting your business expenses. The tax rate is about 15.3%, combining 12.4% for Social Security and 2.9% for Medicare.

Imagine you earn $600 a month from selling handmade jewelry online. You spend $150 monthly on supplies and shipping costs. Your net earnings are $450 per month ($600 - $150), which totals $5,400 for the year. To calculate your self-employment tax, multiply $5,400 by 0.153, which equals about $826.

When you file your taxes, you enter this amount on IRS Schedule SE. You will also be able to deduct half of the self-employment tax ($413 in this example) from your income when figuring your income tax. Although 15.3% seems high, the deduction helps lower your overall tax burden.

If your net earnings are below $400 annually, you typically do not owe self-employment tax, but you might still need to file a tax return if you have other income or meet filing requirements.

Why is self-employment tax important for young adults?

Self-employment tax is important because it contributes to Social Security and Medicare, which provide benefits like retirement funds, disability income, and health care when you get older. Starting to pay these taxes early helps you earn credits toward those benefits.

For young adults just starting side jobs or small businesses, paying self-employment tax is often their first experience with tax responsibilities. Unlike regular jobs, no one withholds taxes for you, so you must save money to cover your tax bills. Without planning, you might face unexpected tax payments or penalties.

Understanding how self-employment tax works builds good financial habits. It encourages budgeting for taxes, keeping accurate records, and filing returns on time. These habits help you avoid stress during tax season and increase your confidence managing money as you become more independent.

Several tax terms can be confusing when learning about self-employment tax:

Knowing these terms helps avoid mistakes like missing estimated payments or confusing income types, which can lead to penalties or delayed refunds.

How do you report and pay self-employment tax step-by-step?

Reporting and paying self-employment tax involves several clear steps:

  1. Track income and expenses: Keep careful records of every payment you receive and all business-related costs. For example, keep receipts for materials or software subscriptions.
  2. Calculate net earnings: Add your gross income and subtract your business expenses to find your net earnings. For instance, if you earned $1,000 and spent $200 on supplies, your net earnings are $800.
  3. Fill out Schedule SE: Use IRS Schedule SE to calculate the exact self-employment tax based on your net earnings. The form walks you through multiplying your net income by the tax rate and applying deductions.
  4. File your tax return: Include Schedule SE with your Form 1040 when filing taxes. The self-employment tax amount is added to your total tax owed.
  5. Make quarterly estimated payments: If you expect to owe $1,000 or more in taxes, pay estimated taxes four times a year using Form 1040-ES. The deadlines are usually April, June, September, and January.
  6. Deduct half your self-employment tax: When calculating income tax, deduct half of your self-employment tax from your taxable income to reduce your overall tax bill.

This routine helps you stay organized and avoid penalties. For example, if you earn $2,000 net this year, expect to pay about $306 in self-employment tax ($2,000 x 0.153). Setting aside a portion of each paycheck prevents surprises at tax time.

What should young adults do next if they are newly self-employed?

If you’re new to self-employment, follow these practical steps to manage your tax responsibilities:

For example, if you earn $400 monthly net from freelance writing, save $100 monthly to cover taxes. This habit makes tax season less stressful and helps you avoid penalties.

Frequently asked questions

If I only make a small amount from self-employment, do I still have to pay self-employment tax?

If your net earnings from self-employment are less than $400 per year, you generally do not owe self-employment tax. However, filing a tax return might still be required depending on your total income and other factors.

Can I reduce my self-employment tax by deducting expenses?

Yes. You deduct legitimate business expenses that directly relate to your work, such as supplies or phone costs, from your gross income. This lowers your net earnings and reduces the amount subject to self-employment tax.

How often should I pay self-employment tax?

You pay self-employment tax at tax time when filing your annual return. If you expect to owe $1,000 or more in taxes, you should make quarterly estimated tax payments to avoid penalties.

What if I have a regular job and also do freelance work?

Taxes on your regular wages are taken out by your employer. For freelance income, you are responsible for paying self-employment tax on that income by filing your tax return and possibly making estimated payments.

Where can I get help if I’m filing self-employment taxes for the first time?

Free help is available through IRS resources, Volunteer Income Tax Assistance (VITA), community programs, and tax preparation software. Trusted adults or tax professionals can also provide guidance.
