Self-employment (SE) tax is the mechanism by which self-employed individuals pay into the Social Security and Medicare systems. When you work as an employee, your employer pays half of your Social Security and Medicare taxes (7.65%) and withholds the other half from your paycheck. When you are self-employed — as a freelancer, sole proprietor, independent contractor, or single-member LLC — you are simultaneously the employer and the employee, so you pay both halves: a combined rate of 15.3% of net self-employment income. The self-employment tax breaks down into two components. The Social Security portion is 12.4% of net SE income, but it is capped at the Social Security wage base ($168,600 for 2024 — indexed annually for inflation). Income above this threshold is not subject to the 12.4% Social Security tax. The Medicare portion is 2.9% of all net SE income with no cap. Additionally, under the Affordable Care Act, high earners pay an Additional Medicare Tax of 0.9% on SE income above $200,000 (single filer) or $250,000 (married filing jointly). The effective SE tax rate is not quite 15.3% on all gross income. First, SE tax is computed on net SE income (revenue minus business expenses). Second, the IRS allows a deduction of half of SE tax when computing both net SE income and personal income tax — this adjustment partially compensates for the fact that employees get to exclude their employer's payroll tax contribution from their gross income. As a result, the effective SE tax rate on gross SE income is approximately 14.13%. Understanding SE tax is essential for self-employed individuals because it represents a large additional tax obligation beyond income tax — and because there are legitimate strategies to reduce it, particularly through entity structure (S-corporations can reduce SE tax on owner compensation above the reasonable salary threshold) and through meticulous tracking of business deductions.
Net SE Income = Self-Employment Revenue − Business Deductions SE Tax Base = Net SE Income × 92.35% (×0.9235) SE Tax = SE Tax Base × 15.3% (up to SS wage base) + excess × 2.9% Deductible portion of SE Tax = SE Tax × 50% Effective SE Tax on net income ≈ 14.13% (below SS wage base)
- 1Calculate net self-employment income: total SE revenue minus all deductible business expenses (home office, vehicle, equipment, health insurance, professional fees, etc.).
- 2Multiply net SE income by 92.35% to arrive at the SE tax base. This adjustment (= 1 − 7.65%) simulates how employees have their employer-side taxes excluded from gross wages before payroll taxes are computed.
- 3Apply 12.4% Social Security tax to the lesser of the SE tax base or the Social Security wage base ($168,600 in 2024).
- 4Apply 2.9% Medicare tax to the full SE tax base (no cap). If income exceeds $200,000 (single) or $250,000 (married), add 0.9% Additional Medicare Tax on the excess.
- 5Deduct half of the total SE tax when computing adjusted gross income on Form 1040 (above-the-line deduction). This deduction reduces both SE tax (in a circular but IRS-approved calculation) and income tax.
- 6Pay SE tax quarterly via estimated tax payments to avoid underpayment penalties. SE tax is reported on Schedule SE attached to your Form 1040.
SE Tax Base = $73,000 × 0.9235 = $67,416. Since $67,416 < $168,600 (SS wage base), full 15.3% applies: $67,416 × 15.3% = $10,315, or approximately $10,343 using exact IRS computation. The self-employed designer can deduct $5,171 (half of SE tax) from gross income, reducing both income tax and AGI. Total tax obligation on $73K net SE income: SE tax $10,343 + income tax (varies by bracket) + possibly state income tax.
SS portion: $168,600 × 12.4% = $20,906. Medicare on full base: $203,170 × 2.9% = $5,892. Additional Medicare Tax (0.9%) on income above $200,000: ($220,000 − $200,000) × 0.9% = $180. Total SE tax ≈ $26,978. The Additional Medicare Tax kicks in because net SE income exceeds $200,000 for a single filer, adding to the already significant SE tax burden. The deductible half = approximately $13,489.
As a sole proprietor, SE tax = $150,000 × 0.9235 × 15.3% ≈ $21,226. As an S-corp owner: payroll taxes on $70,000 salary = both halves ≈ $10,710 (employer + employee). Distributions are not subject to SE tax. Total payroll tax cost ≈ $10,710. Annual savings ≈ $10,516 + additional savings from deductible employer payroll taxes. S-corp formation costs and accounting fees reduce the net benefit — it typically makes economic sense when SE income exceeds $60,000–$80,000 annually.
Each spouse computes SE tax separately on their own Schedule SE. Spouse 1: $95,000 × 0.9235 × 15.3% = $13,430. Spouse 2: $65,000 × 0.9235 × 15.3% = $9,193. Each deducts half their own SE tax from their own income. The Additional Medicare Tax ($200K single threshold) does not apply because neither individual exceeds $200K — however, the $250K threshold for MFJ does not trigger it either at $160K combined.
Because $90,000 of W-2 wages already count toward the SS wage base, only $168,600 − $90,000 = $78,600 of the $30,000 SE income is subject to SS tax (all of it, since $30K < $78,600 remaining). SE Tax Base = $30,000 × 0.9235 = $27,705. SS: $27,705 × 12.4% = $3,435. Medicare: $27,705 × 2.9% = $803. Total SE tax ≈ $4,238 — much less than if the freelance income were the only income because the W-2 already consumed most of the SS wage base.

Why is SE tax 15.3% when employees only pay 7.65%?
Employees pay 7.65% of wages (6.2% SS + 1.45% Medicare) while their employer pays a matching 7.65% — for a combined 15.3% total. Self-employed individuals don't have a separate employer, so they pay both halves themselves. This is why the SE tax rate appears to be double the employee's share. To partially level the playing field, the IRS allows self-employed individuals to deduct half of their SE tax as an above-the-line adjustment to income.
How do I calculate my SE tax deduction?
You can deduct 50% of your self-employment tax as an adjustment to gross income on Schedule 1 of Form 1040. This deduction reduces your adjusted gross income (AGI), which in turn can reduce your income tax liability. It does not reduce your SE tax itself. The deduction recognizes that the employer's share of payroll taxes is deductible as a business expense for regular employers — this gives self-employed individuals a similar (though not identical) benefit.
What business expenses reduce SE tax?
Any legitimate business deduction reduces net SE income, which directly reduces SE tax. Key deductions include: home office deduction (square footage method or simplified $5/sq ft), vehicle expenses (actual cost or standard mileage rate of 67 cents/mile in 2024), equipment and technology (often 100% first-year deduction via Section 179), professional development, health insurance premiums (self-employed health insurance deduction is separate and above-the-line), retirement plan contributions (SEP-IRA, Solo 401k), and professional fees.
Can I avoid SE tax by forming an LLC?
A single-member LLC (SMLLC) is a 'disregarded entity' for federal tax purposes — you still file Schedule C and pay SE tax exactly as a sole proprietor. A multi-member LLC is taxed as a partnership by default. To reduce SE tax, you need to elect S-corporation status (either by forming an S-corp or electing S-corp tax treatment for an LLC) and pay yourself a 'reasonable salary' for the work you perform, with remaining profits distributed without SE tax.
How do I pay SE tax — is it quarterly?
SE tax is not withheld from paychecks because you are self-employed. Instead, you must make quarterly estimated tax payments to the IRS (typically due April 15, June 15, September 15, and January 15 of the following year). These payments cover both income tax and SE tax. Failing to pay adequate quarterly estimates can result in an underpayment penalty, even if you pay all taxes owed when you file your return. Use IRS Form 1040-ES to calculate estimated payments.
What is the self-employed health insurance deduction and does it reduce SE tax?
Self-employed individuals can deduct 100% of health insurance premiums paid for themselves and their families as an above-the-line deduction from gross income. However, this deduction does NOT reduce net SE income (the base for SE tax) — it only reduces income tax. This is different from other business deductions that reduce Schedule C net profit and therefore reduce SE tax. To reduce SE tax, health insurance must be treated as a business expense on Schedule C if you are an S-corp owner/employee.
How does a SEP-IRA or Solo 401(k) affect SE tax?
Retirement plan contributions (SEP-IRA, Solo 401k, SIMPLE IRA) are deducted from gross income as above-the-line adjustments, reducing income tax but NOT SE tax. SE tax is computed on net Schedule C income before retirement deductions. However, the maximum SEP-IRA contribution (25% of net SE income, up to $69,000 in 2024) is calculated based on the reduced net SE income after the SE tax deduction — making the calculation circular and requiring a specific IRS worksheet or tax software.
What happens to my Social Security benefits if I pay SE tax?
Your SE tax payments (specifically the Social Security portion) directly fund your Social Security benefit credits. Each year of SE income at or above the annual threshold ($6,920 in 2024) earns you 4 Social Security credits (the maximum per year). Your future retirement benefit is calculated based on your 35 highest-earning years, whether from W-2 wages or SE income. Self-employed individuals who diligently pay SE tax on their actual income accrue full Social Security benefits — but years with minimal reported SE income permanently reduce future benefits.
Pro Tip
If your net SE income consistently exceeds $60,000–$80,000 per year, model the S-corporation strategy carefully. The annual accounting costs ($1,500–$3,000) must be weighed against the payroll tax savings. At $100K net income, the savings can be $5,000–$10,000 annually — a compelling return on the administrative investment.
Did you know?
The self-employment tax has been 15.3% since 1990. It funds one of the largest programs in the US federal budget — Social Security and Medicare. In 2023, Social Security and Medicare together cost approximately $2.7 trillion, representing about 44% of all federal spending.
