Choosing between Corp-to-Corp vs W2 comes down to who bears the tax and administrative load and who controls the work. As a W2 employee, the hiring company withholds your taxes, pays half of your Social Security and Medicare, offers benefits, and directs how you work. Under a Corp-to-Corp (C2C) arrangement, you form your own LLC or S-Corporation, contract with the client business-to-business, keep the gross payment, and handle every tax, benefit, and insurance cost yourself. The right choice depends on your income level, appetite for running a business, and how much you value predictability against flexibility and deductions.
What Each Arrangement Actually Is
In a W2 arrangement, the hiring organization engages you directly as an individual. The employer sets your schedule, location, methods, and reporting structure, and you fit inside the company’s policies and hierarchy. The person doing the work and the person receiving the paycheck are the same legal entity, which keeps the relationship simple but limits your independence.
A Corp-to-Corp arrangement is a contract between two businesses. The client signs with your legal entity — usually an LLC or S-Corporation that you own — and pays your company, which then pays you. To set this up, you form the entity with your state, obtain a federal Employer Identification Number (EIN) from the IRS, register for applicable state taxes, and keep the entity in good standing.1Internal Revenue Service. Employer Identification Number Annual state filing fees to keep an LLC or corporation active range from nothing in some states to several hundred dollars in others.
The entity type matters. A single-member LLC is treated as a sole proprietorship by default, so all net income flows to your personal return and is subject to self-employment tax. An S-Corporation lets you split income between a salary (subject to payroll taxes) and distributions (not subject to those taxes). S-Corporation owners must pay themselves a reasonable salary before taking distributions, and the IRS can reclassify distributions as wages if the salary is unreasonably low.2Internal Revenue Service.

Taxes and Take-Home Pay
This is where the two arrangements diverge most sharply. As a W2 employee, your employer withholds federal and state income taxes from every paycheck along with FICA: 6.2 percent for Social Security and 1.45 percent for Medicare. The employer matches those amounts out of its own pocket.3Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates Social Security tax applies only up to $184,500 in earnings for 2026.4Social Security Administration. Contribution and Benefit Base Year-end, the employer reports everything on Form W-2.
In a C2C arrangement, the client pays the full contract amount to your business with no withholding. Your business handles every tax obligation. If your entity is a sole proprietorship or single-member LLC, you owe self-employment tax of 15.3 percent on net earnings — the full employer and employee shares of Social Security (12.4 percent) and Medicare (2.9 percent) combined.5Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) If your net self-employment earnings exceed $200,000 ($250,000 for married couples filing jointly), an additional 0.9 percent Medicare tax applies to the amount above the threshold.3Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates
Two things soften the blow. You can deduct the employer-equivalent half of your self-employment tax when calculating adjusted gross income, which reduces income tax liability.6Internal Revenue Service. Topic No. 554, Self-Employment Tax And if you operate as an S-Corporation and pay yourself a reasonable salary, self-employment tax applies only to the salary portion, not distributions. At higher income levels, that split can produce meaningful savings.
Business Expenses and the QBI Deduction
C2C contractors deduct ordinary and necessary business expenses — equipment, software, travel, home office costs, professional development, and business insurance premiums — before arriving at taxable income.7Office of the Law Revision Counsel. 26 U.S. Code 162 – Trade or Business Expenses These reduce both income tax and self-employment tax. W2 employees largely lost the ability to deduct unreimbursed work expenses after 2017 tax reform eliminated the miscellaneous itemized deduction. If your employer doesn’t reimburse a purchase, you generally cannot write it off.
Through the 2025 tax year, owners of pass-through entities like S-Corporations and sole proprietorships could deduct up to 20 percent of their qualified business income under Section 199A, a break unavailable to W2 employees.8Internal Revenue Service. Qualified Business Income Deduction The deduction was scheduled to expire after December 31, 2025, though legislation was introduced to extend and increase it to 23 percent starting in 2026. Confirm the current status before factoring it into your planning.
Benefits and Legal Protections You Give Up
W2 employment comes bundled with a package of benefits and legal protections that C2C contractors must replace on their own or forgo entirely.
- Health insurance. Employers with 50 or more full-time employees must offer affordable coverage or face potential penalties under the Affordable Care Act, and they typically pay a substantial share of the premium. As a C2C contractor, you buy coverage on the individual market or marketplace, though premiums are generally deductible as a business expense.9Internal Revenue Service. Employer Shared Responsibility Provisions
- Overtime and minimum wage. The Fair Labor Standards Act guarantees non-exempt employees at least minimum wage and time-and-a-half beyond 40 hours a week. Independent contractors are excluded from these protections.10Federal Register. Employee or Independent Contractor Classification Under the Fair Labor Standards Act
- Unemployment insurance. Employers pay federal unemployment tax (FUTA) at an effective rate of 0.6 percent on the first $7,000 of each employee’s wages, plus state unemployment taxes. C2C contractors cannot collect unemployment benefits when a contract ends.11Internal Revenue Service. Topic No. 759, Form 940, Employers Annual Federal Unemployment Tax Act (FUTA) Tax Return
- Family and medical leave. W2 employees at covered employers may qualify for unpaid, job-protected leave under the Family and Medical Leave Act. Independent contractors have no equivalent protection.
- Retirement plan access. Many employers offer 401(k) plans with matching contributions. C2C contractors set up their own retirement accounts instead.
Health insurance premiums, retirement matching, and payroll tax contributions together can represent a substantial share of total compensation. When comparing a W2 salary to a C2C hourly or contract rate, price out what it will cost to replace these on your own. A common rule of thumb is that a C2C rate needs to be meaningfully higher than the equivalent W2 salary to come out ahead once benefits and self-employment tax are accounted for.
Costs You Take On
W2 employers provide the tools you need and carry mandatory coverage like workers’ compensation and unemployment insurance. You never see those costs, but they’re baked into what it costs the employer to keep you.
C2C contractors carry these costs directly. Clients commonly require your business to hold insurance before signing:
- General liability insurance for bodily injury and property damage claims. Many contracts require at least $1,000,000 per occurrence.
- Professional liability (errors and omissions) insurance for claims arising from mistakes in your professional services. Required limits often start at $1,000,000 per occurrence.
- Cyber liability insurance, increasingly required for IT and technology contractors handling sensitive data. Some large clients require limits of $5,000,000 or more.
Beyond insurance, you buy your own equipment, maintain professional certifications, and pay for accounting and legal help. Workers’ compensation for yourself is generally optional — most states let business owners exempt themselves — though some clients require it.
How and When You Get Paid
W2 employees are paid on a recurring cycle, usually biweekly or semimonthly, and most state labor laws require payment at least semimonthly or monthly.12U.S. Department of Labor. State Payday Requirements Miss a payday and there is legal recourse. C2C contractors invoice the client’s accounts payable department, and payment timing is governed by the contract. Net 15, Net 30, and Net 60 are common, meaning payment is due 15, 30, or 60 days after the invoice date. Your business may wait a month or two after finishing work before cash arrives, so budget for the gap or line up credit before starting out.
Retirement Savings Options for C2C
W2 employees typically save through an employer-sponsored 401(k), often with a match. C2C contractors can set up their own accounts, and the contribution limits are higher than most W2 workers see.
- Solo 401(k). Available to self-employed individuals with no employees other than a spouse. For 2026, you can defer up to $24,500 as the employee, plus make employer profit-sharing contributions of up to 25 percent of net self-employment income. Catch-up contributions apply at 50 and older. The combined total can exceed $70,000 depending on your age and income.13Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
- SEP IRA. Simpler to set up and administer. You can contribute up to 25 percent of net self-employment income, capped at $69,000 for 2026. All contributions come from the employer side; there is no separate employee deferral.14Internal Revenue Service. SEP Contribution Limits (Including Grandfathered SARSEPs)
A Solo 401(k) generally allows higher total contributions at moderate income levels because of the employee deferral. A SEP IRA wins on simplicity and lower administrative burden. Contributions to either are typically due by your tax filing deadline, including extensions.
Getting Classification Right
The choice between W2 and C2C isn’t purely yours or the client’s. Labeling a worker as a C2C contractor when the relationship actually functions like employment creates legal exposure for both sides. The IRS, the Department of Labor, and state agencies each apply their own tests, and any of them can investigate independently.15Internal Revenue Service. Worker Classification 101: Employee or Independent Contractor If the IRS reclassifies a contractor as an employee, the hiring company can be liable for unpaid employment taxes and penalties, and state agencies may pursue unpaid unemployment insurance and workers’ compensation premiums. For the worker, reclassification can mean losing business expense deductions and amending prior returns.
A genuine C2C relationship looks like independence in substance, not just on paper: you use your own tools, control your schedule, have the freedom to take on other work, and operate through a real business entity. Simply calling someone a contractor without changing how the work actually happens protects no one.
