Self Employment Tax — Payroll Definition

What is Self-Employment Tax (SE Tax)?

Self-employment tax generally combines a 12.4% Social Security component and a 2.9% Medicare component, applied through Schedule SE to the portion of net earnings specified by IRS rules. The Social Security wage base also applies, including wages from an employee job, and Additional Medicare Tax may apply. A person with $400 or more of net earnings from self-employment generally must file Schedule SE. The income-tax deduction is for the employer-equivalent portion of self-employment tax, not a blanket deduction of gross receipts.

How to apply this payroll definition

Locate the label beside its current-period amount, taxable-wage basis, and year-to-date total. Compare it with prior genuine statements, benefits materials, the employer's payroll documentation, and the primary source linked on this page. The same abbreviation can carry a different employer-specific meaning.

What the label does not prove

A familiar term or plausible amount does not authenticate a pay statement or confirm identity, employment, wages, deductions, tax compliance, or eligibility. Ask the verified payroll contact about an unknown code. Use current agency instructions or a qualified adviser when a rate, filing, benefit, garnishment, or legal decision depends on the answer.
