The 15.3% Social Security and Medicare tax you pay on your own net earnings when no employer is withholding half of it for you.
Self-employment tax is Social Security and Medicare tax collected directly from people who work for themselves. An employee sees those taxes come out every payday, with the employer paying a matching half. A sole proprietor, freelancer, gig driver or single-member LLC owner has nobody to split with, so the IRS collects both halves: 12.4% for Social Security and 2.9% for Medicare, a combined 15.3%. It is not charged on everything you invoice. It applies to net earnings — what is left after deductible business expenses — and only 92.35% of that net figure is subject to the tax. The Social Security piece stops once your combined wages and net self-employment earnings reach the annual wage base, $184,500 in 2026. The Medicare piece never stops. Above $200,000 (single, head of household, qualifying surviving spouse), $250,000 married filing jointly, or $125,000 married filing separately, an extra 0.9% applies on top. You owe it once net earnings reach $400 for the year, or $108.28 of church employee income. It is figured on Schedule SE and is separate from income tax, which is why a freelancer can owe no income tax and still owe self-employment tax. One offset softens it: in figuring adjusted gross income you deduct one-half of the self-employment tax. Because nothing is withheld from a 1099 payment, the tax is normally paid in quarterly estimated payments on Form 1040-ES; the IRS generally expects estimated payments from anyone who expects to owe $1,000 or more at filing. These figures change annually — read the IRS page for the year in question, and take your own numbers to a tax professional.
Tax entries on a pay statement depend on taxable wages, current employee elections, filing status, pay frequency, jurisdiction, and current agency instructions. Compare the current-period amount with year-to-date totals and the employer-issued record before treating it as final.
When this term appears on a statement, read its label, current amount, year-to-date amount, pay-period context, and any adjacent rate or hours together. Resolve a mismatch with the original issuer or the cited authority rather than changing a record to force a preferred result.
Example
2026, sole proprietor, $60,000 of net profit. Only 92.35% is taxed: $60,000 x 0.9235 = $55,410. Social Security portion: $55,410 x 12.4% = $6,870.84 (all of it counts, since $55,410 is under the $184,500 wage base). Medicare portion: $55,410 x 2.9% = $1,606.89. Self-employment tax for the year = $8,477.73. Half of that, about $4,239, comes off your income when figuring adjusted gross income. Split across four estimated payments, this one tax runs about $2,119 per quarter.
