This question comes up constantly from people just getting started in government contracting. The good news: the federal government does not have a preference for one business structure over another. What matters is that you are a legal entity with a valid EIN and an active SAM registration.
Can a Sole Proprietor Win Government Contracts?
Yes. Sole proprietors can register in SAM.gov, bid on contracts, and receive awards. You register under your own name with your Social Security Number as the tax ID (or with an EIN if you have one). Nothing in FAR prohibits sole proprietors from contracting with the federal government.
That said, most experienced contractors eventually move to a formal business structure — usually an LLC or S-Corp — for liability protection and tax efficiency.
LLC vs S-Corp vs C-Corp: The Practical Differences
LLC (Limited Liability Company) is the most common choice for new government contractors. It provides personal liability protection, is relatively cheap to set up ($50–$500 in state filing fees), and is flexible in how it is taxed. Single-member LLCs are taxed as sole proprietors by default; multi-member LLCs are taxed as partnerships. You can elect S-Corp taxation.
S-Corporation makes more sense once your net profit exceeds roughly $50,000–$80,000 per year. The S-Corp lets you split income between salary and distributions, reducing self-employment taxes. The savings can be meaningful at higher income levels. Downside: more administrative complexity, payroll requirements, and restrictions on ownership (cannot have foreign shareholders, limited to 100 shareholders).
C-Corporation is rarely the right choice for small government contractors. C-Corps pay corporate income tax, and profits are taxed again when distributed — the dreaded double taxation. They are primarily relevant if you plan to raise venture capital or go public, which is not the typical path for a small government contractor.
How Business Structure Affects Certifications
Some certifications are sensitive to business structure:
- 8(a) — Requires that a socially and economically disadvantaged individual own and control at least 51% of the business. Structure affects how ownership and control are demonstrated.
- WOSB — Requires that women own and control at least 51%. Same issue.
- SDVOSB — VA's Vets First program and SBA's SDVOSB certification both require veteran ownership and control.
For all of these, the ownership and control analysis looks through the business structure to the actual humans involved. An LLC with clear single ownership is simple. Complex corporate structures with multiple layers can create certification problems.
What Most New Contractors Do
The practical answer for most people starting out: form a single-member LLC in your state, get an EIN from the IRS (free, instant online), open a business bank account, and register in SAM.gov. This setup handles the liability protection concern, is clean for tax purposes, and does not create complications for certifications.
Work with a CPA who has government contractor clients to figure out when switching to S-Corp taxation makes sense for your income level.
