How to Calculate and Pay Self-Employment Tax: Complete Guide 2026

8 min read

BURBANK, Calif. — Self-employment tax, which includes Social Security and Medicare taxes, applies to net earnings from self-employment for the 2026 tax year. For individuals earning $400 or more, understanding how to calculate and pay this tax is essential for compliance with IRS regulations.

Understanding Self-Employment Tax

Self-employment tax is comprised of two parts: Social Security and Medicare taxes. According to the IRS, the total self-employment tax rate for 2026 is 15.3%, with 12.4% allocated to Social Security and 2.9% to Medicare.[1] This tax applies to any earnings from self-employment, including wages, commissions, and bonuses, but excludes most passive income such as dividends and interest.

Who is Subject to Self-Employment Tax?

Self-employment tax applies to individuals who earn at least $400 in net profit from self-employment during the tax year. This encompasses freelancers, sole proprietors, and partners in a partnership.[2] Individuals should file Schedule SE (Form 1040) to determine their self-employment tax.

Calculating Self-Employment Tax

Calculating self-employment tax involves a few key steps, which are detailed below.

Step 1: Calculate Your Net Earnings

To determine taxable income, subtract all business expenses from gross income. The IRS defines net earnings from self-employment as the total business income minus allowable business deductions. According to IRS guidelines, sole proprietors report this on Schedule C (Form 1040).

Step 2: Apply the Self-Employment Tax Rate

The net earnings are then multiplied by 92.35% (value as of 2026) to account for the deduction allowed under Section 162(l) of the Internal Revenue Code, which indicates that only 92.35% of one's net earnings counts towards self-employment tax.[3] The resulting figure is then multiplied by the 15.3% self-employment tax rate.

For example, if net earnings are $50,000:

  • Step 1: $50,000 (net earnings)
  • Step 2: $50,000 x 0.9235 = $46,175 (taxable income)
  • Step 3: $46,175 x 15.3% = $7,060.88 (self-employment tax)

Step 3: Complete Schedule SE

To report self-employment income and calculate the tax, complete Schedule SE and attach it to your Form 1040. Make sure to include any applicable deductions on your prior year’s tax return, or for any estimated payments made during the year.

Paying Self-Employment Tax

Self-employment tax is typically due with an individual’s federal income tax return. For 2026, the deadline for filing is April 15. However, self-employed individuals are also responsible for making estimated tax payments throughout the year.

Estimated Tax Payments

For those likely to owe $1,000 or more in tax, estimated tax payments may be required quarterly, with due dates on April 15, June 15, September 15, and January 15 of the following year.[4] These payments should be calculated using Form 1040-ES.

Failure to Pay Penalties

Failure to pay self-employment tax can lead to penalties and interest. The IRS penalizes underpayment of estimated tax payments when there is a 10% or more shortfall in the estimated amount owed. Keeping accurate records and making timely payments is key to avoiding these penalties.

State Considerations

Self-employed individuals should also be aware of California state taxes. California typically mirrors federal tax policies, but taxpayers must also pay the state’s self-employment tax as part of the California income tax return.

Local Taxes

Additionally, some cities impose local business taxes. It is essential for business owners in California to consult local regulations to ensure compliance, particularly in Burbank where local ordinances may apply.

Record-Keeping

Maintaining accurate records of income and expenses is crucial for compliance and effective calculation of self-employment tax. Utilize accounting software or spreadsheets to track finances consistently. The IRS recommends keeping records for at least three years from the date the tax return is filed.[5]

Preparing for Potential Changes

Changes in tax law are anticipated for upcoming years, making it imperative for self-employed individuals to stay informed. Regular review of IRS publications and annual tax guidelines will help in effective tax planning.

For example, the IRS has proposed expanding the Self-Employment Income Tax Revisions for the 2027 tax year, which may impact how earnings and taxes are assessed.[6]

Tax professionals counsel individuals to review their gross income regularly and plan ahead for tax implications associated with business growth.

Broader Implications

Understanding self-employment tax is vital for effective business operation and compliance with federal and state taxes. As tax laws continue to evolve, staying informed will mitigate risks associated with penalties and optimize tax obligations.
