Self-employed in the U.S.? Learn key tax obligations for 2026, including estimated payments, filing requirements, and financial strategies to stay compliant and maximize savings.

Who is Considered Self-Employed?

In the U.S., self-employed individuals include sole proprietors, freelancers, contractors, and gig workers. If you earn $400 or more from your business, you are required to file taxes. As a self-employed person, you are responsible for both income tax and self-employment tax (Social Security & Medicare contributions).

Quarterly Estimated Tax Payments

As a self-employed entrepreneur, you are generally required to make quarterly estimated tax payments. These payments cover both your income tax and self-employment tax.

  • Due Dates: Payments are typically due on April 15, June 15, September 15, and January 15.

  • Penalties: If you don’t pay enough throughout the year, you could face penalties, even if you are due a refund when you file your annual return.

  • It’s important to accurately estimate your income and expenses each quarter to avoid underpayment penalties.

Annual Tax Filing

Each year, self-employed individuals must file their tax return using Form 1040, with Schedule C to report business income and expenses. Schedule SE is used to calculate self-employment tax.

Taxes are due by April 15 (extensions available). Be sure to include all business deductions to reduce your taxable income. If you haven't paid enough during the year, you may owe additional taxes when filing.

2026 Inflation Adjustments

The IRS adjusts several tax parameters annually to account for inflation, which may impact self-employed individuals:

  • For 2026, the standard deduction for single filers has increased to $13,850.

  • These adjustments can affect your overall tax liability and may present new opportunities to reduce your taxable income through increased deductions.
