Being self-employed means you earn your income by running your own trade or business instead of drawing a paycheck from an employer. For federal tax purposes, once your net earnings from that work hit $400 in a year, you owe self-employment tax: a 12.4% Social Security levy on the first $184,500 of earnings in 2026, plus a 2.9% Medicare levy on all of it.1Office of the Law Revision Counsel. 26 USC 1401 – Rate of Tax2Social Security Administration. Contribution and Benefit Base The label also changes which forms you file, what you can deduct, and which retirement accounts you can open.
Who Counts as Self-Employed
The most common form is the sole proprietorship. You and the business are the same legal entity, you don’t file formation paperwork with the state, and you just start working. Freelancers, gig workers, and independent contractors usually fall here, whether they serve one client or dozens.
Partners in a partnership are self-employed too, because they own the business rather than work for it. The IRS applies that treatment to partners in limited liability partnerships and limited liability limited partnerships as well.3Internal Revenue Service. Self-Employment Tax and Partners Owners of a single-member LLC that has not elected corporate tax treatment are in the same bucket. An LLC shields you from some personal liability for business debts, but it doesn’t change your self-employment status for federal tax purposes.
You can generally use your Social Security number to operate as a sole proprietor. If you hire employees or set up a retirement plan, you’ll need an Employer Identification Number from the IRS. Many sole proprietors get one anyway to keep personal and business banking separate.4Internal Revenue Service. Get an Employer Identification Number
Employee or Independent Contractor
Calling yourself an independent contractor in a contract doesn’t make you one. The IRS looks at how the relationship actually works and weighs three categories of evidence.5Internal Revenue Service. Worker Classification 101: Employee or Independent Contractor
- Behavioral control. Does the hiring party dictate how, when, and where the work happens? Step-by-step training on company methods looks like an employee relationship. A genuinely self-employed person picks their own approach.
- Financial control. Do you invest in your own equipment, advertise to the public, and stand to make a profit or take a loss? Unreimbursed expenses and the freedom to take on other clients point to self-employment.
- Relationship factors. Health insurance, a pension, or a written contract describing permanent employment all signal an employer-employee bond.
No single factor is decisive. The IRS looks at the full picture, and a contract label won’t override the day-to-day reality of the arrangement.
How the Self-Employment Tax Works
Self-employment tax covers Social Security and Medicare, the same payroll taxes traditional employers and employees split. When you work for yourself, you pay both halves. The combined rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.1Office of the Law Revision Counsel. 26 USC 1401 – Rate of Tax
The Social Security portion applies only to the first $184,500 of net self-employment earnings in 2026.2Social Security Administration. Contribution and Benefit Base Every dollar above that is exempt from Social Security tax. Medicare has no cap and applies to all earnings. High earners face an additional 0.9% Medicare surtax on self-employment income above $200,000 for single filers or $250,000 for married couples filing jointly.6Internal Revenue Service. Topic No. 560, Additional Medicare Tax
You don’t pay the tax on every dollar of net profit. The IRS applies it to 92.35% of your net earnings, mirroring the break traditional employees get because their employer’s share of payroll tax isn’t counted as wages.7Internal Revenue Service. Topic No. 554, Self-Employment Tax A Schedule C showing $100,000 in net profit produces a taxable base of $92,350.
You can then deduct half of your self-employment tax when calculating adjusted gross income. This is an above-the-line deduction, so you get it whether you itemize or take the standard deduction.8Office of the Law Revision Counsel. 26 USC 164 – Taxes It doesn’t reduce the self-employment tax itself, but it does lower your income tax. Many self-employed people miss it.
Filing and Paying as You Go
Sole proprietors and single-member LLC owners report business income and expenses on Schedule C (Form 1040), which produces your net profit or loss for the year.9Internal Revenue Service. About Schedule C (Form 1040), Profit or Loss from Business (Sole Proprietorship) That figure flows to Schedule SE, where the self-employment tax is computed.10Internal Revenue Service. About Schedule SE (Form 1040), Self-Employment Tax Partnership income comes through a Schedule K-1 instead, but Schedule SE works the same way.
Without an employer withholding taxes from each paycheck, you’re expected to pay as you earn. If you expect to owe $1,000 or more in federal tax for the year after subtracting withholding and credits, you generally have to make quarterly estimated payments.11Internal Revenue Service. Estimated Taxes The four deadlines for 2026 are April 15, June 15, September 15, and January 15, 2027.12Internal Revenue Service. 2026 Form 1040-ES – Estimated Tax for Individuals You can skip the January payment if you file your full return and pay the balance by February 1, 2027.
You avoid underpayment penalties by hitting one of two safe harbors: pay at least 90% of the tax you’ll owe for 2026, or pay 100% of what you owed for 2025. If your 2025 adjusted gross income exceeded $150,000 ($75,000 if married filing separately), that second safe harbor rises to 110% of prior-year tax.12Internal Revenue Service. 2026 Form 1040-ES – Estimated Tax for Individuals First-year filers with no prior baseline typically aim for the 90% threshold.
This is where new freelancers get burned. They treat all their revenue as spendable cash, then face a five-figure bill in April. Setting aside roughly 25% to 30% of each payment in a separate account is a rough but reliable cushion for most earners below the Social Security cap.
Deductions That Come With the Status
Home Office
Use part of your home exclusively and regularly as your principal place of business and you can deduct a portion of housing costs. The simplified method allows $5 per square foot of dedicated office space, up to 300 square feet, for a maximum of $1,500 a year.13Internal Revenue Service. Simplified Option for Home Office Deduction The regular method calculates the actual business-use percentage of your home and applies it to real expenses like rent, utilities, and insurance. It can produce a larger deduction but demands better records.
Self-Employed Health Insurance
You can deduct premiums for medical, dental, and vision insurance for yourself, your spouse, and your dependents. The deduction is taken on your personal return, not Schedule C, and reduces adjusted gross income directly. One catch: you can’t claim it for any month in which you were eligible to participate in a subsidized health plan through a spouse’s employer, even if you didn’t enroll.14Internal Revenue Service. Instructions for Form 7206
Qualified Business Income
The Section 199A deduction lets many sole proprietors, partners, and S corporation owners deduct up to 20% of qualified business income from taxable income.15Internal Revenue Service. Qualified Business Income Deduction Originally set to expire at the end of 2025, it was made permanent under the One Big Beautiful Bill Act. Income earned through a C corporation or as a W-2 employee doesn’t qualify.
The full 20% is available without restriction if 2026 taxable income falls below $201,750 for single filers or $403,500 for married couples filing jointly. Above those thresholds, limits based on wages paid and property held by the business begin to phase in, and service-based businesses like law, accounting, and consulting face steeper restrictions as income climbs. Below the threshold the math is simple: a Schedule C showing $80,000 in qualified business income supports a $16,000 deduction.
Retirement Accounts You Can Open
You don’t have a company 401(k) with an employer match, but you do have access to retirement accounts with generous contribution limits that can meaningfully reduce taxable income.
A SEP IRA takes contributions of up to 25% of your net self-employment earnings, capped at $72,000 for 2026. Setup is simple and contributions are tax-deductible. There is no catch-up provision for older workers, and the percentage cap means you need very high earnings to reach the dollar ceiling.16Internal Revenue Service. SEP Contribution Limits (Including Grandfathered SARSEPs)
A solo 401(k) lets you contribute in two roles. As the employee, you can defer up to $24,500 in 2026. As the employer, you can add a profit-sharing contribution of up to 25% of net self-employment earnings. Combined totals cap at $72,000 under age 50, $80,000 at 50 or older, and $83,250 between ages 60 and 63 thanks to the enhanced catch-up under SECURE 2.0.17Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
The solo 401(k) is the stronger tool for most self-employed people earning less than roughly $290,000, because the employee deferral lets you shelter more income at lower earning levels than the SEP’s percentage-only formula. At very high incomes the two converge. The solo 401(k) also offers an optional Roth feature that the SEP does not.
What to Keep and For How Long
Every deduction needs documentation. Keep receipts, bank statements, invoices, and mileage logs supporting the income and expenses on your return. The IRS generally requires you to retain these records for three years from your filing date. Underreport gross income by more than 25% and the window stretches to six years. Claims involving worthless securities or bad debts require seven years.18Internal Revenue Service. How Long Should I Keep Records Going digital and keeping everything for seven years is the simplest approach. Storage is cheap. Reconstructing records during an audit is not.
