First-Year Self-Employed Taxes: What Changes and What to Expect

What Counts as Self-Employment for Tax Purposes?

For federal income tax purposes, you are generally considered self-employed if you operate a trade or business as:

• An independent contractor
• A freelancer
• A gig worker
• A sole proprietor
• A single-member limited liability company treated as a sole proprietorship
• Part of a qualified joint venture
• A self-employed person receiving church employee income
• Partners filing Form 1065 Partnership return

If you receive earnings from self-employment and are not treated as an employee, you are typically responsible for reporting that business income yourself.

Self-employment income includes:

• Payments reported on Form 1099-NEC
• Certain payments reported on Form 1099-K
• Direct client payments
• Cash income you are required to report

Your net profit is generally your business income minus ordinary and necessary business expenses reported on Schedule C. That net profit flows to Schedule SE to calculate self-employment tax.

If you are unsure whether you are considered self-employed, classification depends on multiple IRS factors. Worker classification is not determined by a job title alone.

What Changes in Your First Year of Self-Employment

Becoming self-employed changes how your taxes work, even if your day-to-day job feels similar.

No automatic withholding

When you were a W-2 employee, your employer withheld federal income tax, social security tax, and Medicare taxes from each paycheck.

As a self-employed person, there is generally no automatic withholding. That means you may need to set aside money to pay taxes yourself.

Many first-time filers assume their previous payroll withholding covers everything. However, they do not automatically cover self-employment income.

Self-employment tax may apply

In addition to income tax, you may need to pay self-employment tax, sometimes called SE tax. This generally covers the Social Security and Medicare portions that would normally be split between you and your employer.

Learn more about how this works on our self-employment tax explained page.

Estimated tax payments may be required

If you expect to owe at least $1,000 in tax after credits and withholding, you may need to make estimated tax payments during the year. To avoid penalties, you generally must pay at least 90% of your current-year tax or 100% of your prior-year tax (110% if your prior-year AGI exceeded $150,000).

New forms may appear on your tax return

Your federal income tax return may now include additional forms:

• Schedule C to report business income and expenses
• Schedule SE to calculate self-employment tax
• Form 1040 as your main individual tax return

You can review how these forms relate to each other in our Common Tax Forms guide.

If this is your first Schedule C, that alone can feel intimidating. The good news is that these forms are common for small business owners and self-employed people.

For many people, the confusion increases when self-employment income is added to an existing job. A mixed-income year can change how your tax return looks and how much you may owe.

If You Have Both W-2 and 1099 Income in the Same Year

Many people are self-employed for the first time while still working a regular job. This creates a mixed-income year.

You may have:

• W-2 wages from an employer
• 1099 income as an independent contractor
• Side hustle taxes to account for

This situation is often described as W-2 and 1099 in the same year.

Here is what generally happens:

• Your W-2 wages are reported as usual
• Your self-employment income is reported separately on Schedule C
• Both amounts are included in your gross income
• Self-employment tax may apply to net earnings from self-employment only

W-2 withholding does not automatically cover the self-employment tax portion. That surprise is one of the most common reasons first-year self-employed individuals feel blindsided.

Quarterly Estimated Tax Payments

Estimated tax payments are periodic payments that some self-employed individuals may need to make during the year to cover income tax and self-employment tax.

Details are explained in our Quarterly Estimated Taxes page.

Common First-Year Misconceptions

Let’s clear up a few big ones.

“If I got a 1099, I owe tax on the full amount.”

Not necessarily. Taxes generally apply to net profit, not total gross income. Business expenses may reduce taxable income, but the reporting requirement still exists.

“I only pay income tax.”

Self-employed individuals may owe both income tax and self-employment tax. Self-employment tax covers Social Security and Medicare contributions.

“It was just a small side hustle.”

Even part-time or gig income may need to be reported. Whether you must pay self-employment tax depends on your net earnings and other factors.

“Self-employment tax is optional.”

It is not optional if your earnings exceed applicable thresholds. It is part of federal tax law.

Special Situations

Worker misclassification

Sometimes workers are treated as independent contractors but believe they should be employees. Classification depends on multiple IRS factors involving behavioral control, financial control, and the nature of the relationship.

If there is a dispute, workers can request an official determination using IRS Form SS-8. This process does not automatically reclassify you, but it allows the IRS to review the facts.

Hobby vs business distinction

If the IRS determines your activity is a hobby rather than a business, you’re still required to report any income you earn. However, hobby-related expenses cannot be deducted as business expenses. If your activity is reclassified as a hobby, you may owe back taxes, along with penalties and interest on any losses previously claimed.

To decide whether an activity qualifies as a business or a hobby, the IRS looks at several factors. One key guideline is whether the activity shows a profit in at least three out of five years. This classification directly impacts how your income and expenses are reported on your tax return.

Part-year self-employment

You may have started self-employment mid-year. In that case, only the earnings from self-employment during that portion of the tax year are reported as business income.

Ending self-employment mid-year

If you stopped being self-employed before the end of the tax year, you still report income earned during the active period. Ending the activity does not remove the reporting requirement for that year.

Tax Forms Involved in First-Year Self-Employed Taxes

Here are the primary forms commonly associated with first-year self-employed taxes:

• Schedule C to report business income and expenses
• Schedule SE to calculate self employment tax
• Form 1040 for your individual income tax return
• Form 1099-NEC for nonemployee compensation
• Form 1099-K for certain payment processor transactions

These forms work together to calculate your adjusted gross income and total tax for the year.

What Happens If Ignored

If self-employment income is not reported, the IRS may assess additional tax, as well as failure-to-pay penalties and interest.

This is not meant to alarm you. It simply reflects that tax obligations continue even if income is informal or part-time.

When in doubt, reviewing IRS publications or speaking with a qualified tax professional may provide clarity.
