The core difference is simple: a W2 worker is an employee, and a C2C worker is a business.
A W2 (named after the W-2 tax form) is a traditional employee. The company you hire is their official employer, even if they’re a contractor through a staffing agency. The employer handles all payroll tasks—withholding income taxes, paying their portion of Social Security and Medicare taxes, and offering benefits like health insurance, paid time off, and 401(k) plans. This model gives the company a high degree of control over the worker’s schedule, methods, and responsibilities.
A C2C (Corp-to-Corp) is an arrangement where a company hires another corporation—in this case, the worker’s own incorporated business, such as an LLC or S-Corp—to provide a service. It’s a business-to-business transaction. The company pays the worker’s business, not the individual. The C2C worker is then responsible for all of their own expenses, including paying all taxes (both the employer and employee portions), managing their own benefits, and handling their business’s administration.
Why the Choice Matters to Your Business
The decision to hire a W2 or C2C worker isn’t just about semantics; it has significant implications for how you manage your workforce, your costs, and your legal risks.
- Cost & Overhead: With a W2 employee, you are responsible for a range of payroll taxes and benefits that can add an extra 20-30% to the employee’s base salary. With a C2C contractor, you pay a single negotiated rate, and they handle all their own overhead. C2C rates are typically higher to compensate the worker for their expenses, but your costs are more predictable.
- Control & Liability: Hiring a W2 worker gives you control over how and when they perform their work, which can be crucial for roles that require close supervision and collaboration. This relationship, however, comes with legal obligations. If you misclassify a C2C worker and treat them like an employee (e.g., controlling their hours or requiring them to use your equipment), you run the risk of a serious and costly audit from the IRS.
- Flexibility & Talent Pool: C2C arrangements are great for project-based work that requires specialized, independent expertise. They allow you to bring on a highly skilled individual for a specific outcome without the long-term commitment of hiring a full-time employee. This gives you flexibility and access to a wider pool of talent who prefer to work as independent consultants.
