Open the Calculator →The self-employment tax percentage for 2025–2026 is 15.3%, applied to 92.35% of your net SE income. The rate breaks down as 12.4% Social Security (on income up to $184,500) + 2.9% Medicare (no cap). You deduct 50% of SE tax from gross income before calculating income tax. This deduction does not require itemizing.
- SE tax = 15.3% × (net SE income × 92.35%)
- Social Security: 12.4% on net earnings up to $184,500
- Medicare: 2.9% on all net earnings. No cap.
- Additional Medicare Tax: 0.9% on earnings over $200,000 (single) / $250,000 (MFJ)
- SE threshold: $400 net SE income triggers SE tax filing requirement
- Deduct 50% of SE tax above-the-line when computing AGI
What Is Self-Employment Tax?
Self-employment (SE) tax is the Social Security and Medicare tax paid by self-employed individuals. This covers sole proprietors, freelancers, independent contractors, partners in a partnership, and LLC members taxed as sole proprietors or partnerships.
W-2 employees split FICA taxes evenly with their employer: each pays 7.65% (6.2% SS + 1.45% Medicare). Self-employed individuals pay both halves. The combined rate is 15.3%. For how FICA withholding works on W-2 wages, see our FICA Tax Guide.
To partially offset this, the IRS provides two benefits. First, SE tax is calculated on 92.35% of net SE income, not 100%. Second, you can deduct 50% of SE tax from gross income before calculating income tax. This is the SE tax deduction.
Who Must Pay Self-Employment Tax?
You must pay SE tax if your net self-employment earnings are $400 or more for the tax year. Net earnings = gross SE income minus deductible business expenses reported on Schedule C.
SE tax applies to income earned as:
- Sole proprietor (Schedule C)
- Freelancer or independent contractor (1099-NEC income)
- Partner in a partnership (your distributive share of income)
- LLC member (single-member LLC taxed as sole proprietor, or multi-member LLC taxed as partnership)
- Certain statutory employees (including licensed real estate agents and direct sellers)
Self-Employment Tax Rates for 2026
| Component | Rate | Income Cap |
|---|---|---|
| Social Security Tax | 12.4% | $184,500 (2026 wage base) |
| Medicare Tax | 2.9% | No cap |
| Total SE Tax Rate | 15.3% | SS cap applies to SS portion |
| Additional Medicare Tax | 0.9% | Earnings over $200,000 (single) / $250,000 (MFJ) |
The 2026 Social Security wage base is $184,500, up from $176,100 in 2025. Once your net SE earnings exceed $184,500, the 12.4% SS tax stops. The 2.9% Medicare tax continues on all earnings with no cap.
How to Calculate Self-Employment Tax (Step-by-Step)
Example: A freelance graphic designer has $80,000 in net 1099 income and files as single.
SE Tax Base: $80,000 × 0.9235 = $73,880. SE Tax: $73,880 × 0.153 = $11,304.
SE Deduction: $11,304 × 0.50 = $5,652. AGI: $80,000 − $5,652 = $74,348.
Standard deduction (single, 2026): $16,100. Taxable Income: $74,348 − $16,100 = $58,248. Apply 2026 brackets to $58,248 for income tax.
Use our 1099 Tax Calculator to automate this calculation for any income level and filing status.
Schedule SE: Reporting SE Tax
Use Schedule SE (Form 1040) to calculate and report your SE tax. Attach it to your Form 1040 when filing your return. The IRS provides a short form and a long form. Most self-employed individuals use the short form.
If you have multiple types of self-employment income (e.g., freelance income and a Schedule E partnership distributive share), combine all SE income when completing Schedule SE.
Enter your SE tax from Schedule SE on Form 1040 Schedule 2, Part II. The SE deduction (50% of SE tax) goes on Form 1040 Schedule 1, line 15.
The SE Tax Deduction
The SE tax deduction is one of the most valuable above-the-line deductions for self-employed workers. You deduct exactly 50% of your SE tax from gross income. This reduces your adjusted gross income (AGI). You do not need to itemize to claim it.
The deduction exists because W-2 employees do not pay the employer's share of FICA (7.65%). Their employer pays that portion, and it is not considered income to the employee. Self-employed individuals pay both halves. The deduction partially compensates by reducing the income subject to income tax.
The SE deduction reduces your AGI. A lower AGI can improve eligibility for other deductions and credits that phase out based on income. Examples include IRA contributions, student loan interest, and certain education credits.
Workers who have both SE income and W-2 income may qualify for additional above-the-line deductions under the One Big Beautiful Bill Act. W-2 employees who receive tips in qualifying occupations can claim the No Tax on Tips deduction (IRC § 224) — see our No Tax on Tips Guide for eligibility rules and the qualifying occupation list. W-2 employees who earned FLSA-required overtime pay can claim the No Tax on Overtime deduction (IRC § 225) — see our No Tax on Overtime Guide. These deductions reduce federal income tax only and do not reduce self-employment tax.
Self-employed filers who itemize and pay high state income taxes and property taxes may benefit from the OBBBA SALT cap increase. The cap rose from $10,000 to $40,000 for TY 2025–2029, providing additional Schedule A deduction space for filers in high-tax states. See our SALT Deduction Increase Guide to understand the itemizing requirement and phase-out rules before claiming the higher cap.
Self-employed filers who financed a qualifying new U.S.-assembled vehicle purchased after December 31, 2024 may also be eligible for the OBBBA qualified motor vehicle loan interest deduction. The deduction is capped at $10,000 per return per year for TY 2025–2028 and is above the line — itemizing is not required. If you also use the vehicle in your business, coordinate carefully: the same interest cannot be deducted on both Schedule C and Schedule 1-A. See our Auto Loan Interest Deduction Guide for vehicle eligibility rules, phase-out thresholds, and the MFS disqualification, or use the Auto Loan Interest Calculator to estimate your deduction.
Self-employed filers with young children may also want to review Trump Accounts, a new type of federally created savings account established by the OBBBA. The account provides a $1,000 federal seed for children born after December 31, 2024 and allows annual contributions up to $5,000. Contributions are after-tax and do not affect Schedule SE or current-year tax liability. See our Trump Account Guide for the full structure and distribution rules, or use the Trump Account Calculator to project account growth.
Multiple OBBBA provisions can apply to the same return. The OBBBA Tax Changes Guide covers all six provisions side by side — eligibility rules, phase-outs, Schedule 1-A coordination, and how to stack deductions without double-counting.
Quarterly Estimated Tax Payments
If you expect to owe $1,000 or more in federal tax for the year (after withholding and credits), you are required to pay quarterly estimated taxes throughout the year. Missing payments or underpaying results in an IRS underpayment penalty.
2026 quarterly due dates: Q1 — April 15, Q2 — June 15, Q3 — September 15, Q4 — January 15, 2027.
To avoid penalties, pay the lesser of: (a) 90% of your current year tax liability, or (b) 100% of your prior year tax liability (110% if your prior year AGI exceeded $150,000). This is the safe harbor rule.
Use our Self-Employment Tax Calculator to calculate your SE tax, SE deduction, and estimated income tax for any net earnings amount. For quarterly payment planning, the Quarterly Tax Calculator shows your safe harbor amount, per-quarter payment, and all four 2026 due dates.
Practitioner Insight
At LMN Tax Inc, we see two consistent errors with self-employment tax. First, clients who skip the 92.35% multiplier and calculate SE tax on 100% of gross income instead of net earnings. Second, clients who assume the Medicare portion has a wage base cap. It does not. Every dollar of net SE income is subject to the 2.9% Medicare rate regardless of total earnings. Both errors produce an understated liability and a surprise balance due in April.
Real-World Scenario
James, freelance graphic designer, single filer, TY 2025: James earned $82,000 in gross 1099 income in 2025. After deducting $11,400 in Schedule C business expenses (software, equipment, home office), his net self-employment income is $70,600.
SE tax base: $70,600 x 92.35% = $65,159. SE tax: $65,159 x 15.3% = $9,969. He then deducts 50% of SE tax paid ($4,985) as an above-the-line deduction on Schedule 1. His federal AGI is reduced by that $4,985 before the standard deduction is applied. Total federal income tax on $70,600 minus $4,985 SE deduction minus $15,750 standard deduction = $49,865 taxable income. Federal income tax on $49,865 (single): approximately $6,750.
James's total federal obligation is $9,969 (SE tax) + $6,750 (income tax) = $16,719. He made quarterly estimated payments throughout 2025. Without the SE deduction and the Schedule C deductions, his federal liability would have been significantly higher. The interaction of the 92.35% factor, the 50% SE deduction, and Schedule C expenses is where most of the SE tax savings occur.
When Self-Employment Tax Does Not Apply as Expected
- W-2 income from a business you own through an S-Corp: S-Corp owner-employees pay FICA on their salary only. Distributions above salary are not subject to SE tax. SE tax does not apply to S-Corp distributions. The entity structure changes the tax base entirely. Use the S-Corp Savings Calculator to estimate how much SE tax an S-Corp election could save on your income level.
- Rental income without services: Passive rental income is not self-employment income for SE tax purposes. A landlord who does not provide substantial services to tenants does not pay SE tax on rental profits. Real estate dealers and agents who provide services may be subject to SE tax depending on facts and circumstances. For the full Schedule E mechanics, $25,000 passive loss allowance under IRC §469(i), and depreciation rules, see our Rental Income Tax Calculator and Rental Income Tax Guide.
- Limited partners in a partnership: A limited partner's share of partnership income is generally not subject to SE tax (with limited exceptions). General partners and members in managing member roles are subject to SE tax on their distributive shares.
- Ministers and clergy: Church employees may be subject to SE tax even if the church treats them as employees and issues a W-2. SE tax rules for ministers and clergy are complex and governed by IRC §1402(c). Standard W-2 withholding may not apply.
- Income below $400: SE tax applies only when net self-employment income is $400 or more for the year. Below that threshold, no SE tax is owed and Schedule SE is not required. The $400 threshold applies to net income, not gross receipts.
