Delaware C-Corp vs. LLC for Spinouts
Why VC-backed university spinouts use Delaware C-corps over LLCs: preferred stock, UBTI exposure, QSBS eligibility, and 2025 Section 1202 changes.
Side-by-side comparison
| Dimension | Delaware C-Corp | LLC |
|---|---|---|
| Default tax treatment | Entity-level tax on profits, then shareholder-level tax on dividends ("double taxation") | Pass-through partnership taxation by default; profits/losses flow to members' personal returns |
| Equity instrument for VCs | Preferred stock with standard NVCA model terms (liquidation preference, anti-dilution, board seats) | Membership units / operating-agreement provisions -- no standardized VC market documents |
| QSBS (IRC Section 1202) eligible | Yes -- only domestic C-corp stock qualifies | No -- membership interests never qualify, regardless of tax election |
| Exposure for tax-exempt/offshore VC investors (UBTI) | None -- entity-level tax blocks pass-through exposure | Active trade/business income can pass through as UBTI to exempt/foreign LPs unless a blocker structure is added |
| Governance formalities | Board of directors, required meetings/minutes, statutory officer roles | Minimal statutory formalities; governance set almost entirely by the operating agreement |
| Profit/loss allocation flexibility | Rigid -- tied to share class and ownership percentage | Highly flexible -- can be allocated by negotiated agreement, not just ownership percentage |
| Typical university equity instrument | Common stock (plus possible royalty), sits directly on the cap table alongside investor preferred stock | Membership interest percentage; conversion mechanics into future C-corp shares must be addressed in the license/operating agreement |
| Best fit | Spinouts planning to raise institutional VC and/or maximize QSBS tax benefit at exit | Spinouts funded by grants, royalties, revenue, or a small angel group with no near-term priced VC round |
| Conversion path | N/A -- already the VC-standard entity | Can convert to a Delaware C-corp via statutory conversion or merger before a VC round, at added legal/accounting cost |
Common questions
FAQ
Can a university spinout start as an LLC and convert to a Delaware C-corp later?+
Yes -- typically via a statutory conversion or a merger into a newly formed Delaware C-corp shortly before a priced VC round. It adds legal and accounting cost, and founders should plan the QSBS holding-period start date around the conversion date, since QSBS eligibility only begins once C-corp stock actually exists.
Does an S-corporation solve the VC problem instead of an LLC?+
No. S-corps are pass-through for tax purposes and are capped at 100 shareholders, one class of stock, and no non-individual or non-US-resident shareholders -- incompatible with a VC fund as an investor and with issuing preferred stock.
Does the choice of entity affect the university's Bayh-Dole obligations?+
Not directly -- Bayh-Dole governs the university's own election to retain title and licensing conduct, not the licensee's corporate form. But an LLC-to-C-corp conversion typically requires an assignment-and-assumption amendment to the existing license.
Is a Delaware C-corp always better for a spinout that might never raise VC?+
No. A spinout funded by SBIR/STTR grants, licensing royalties, revenue, or a small angel group with no near-term VC round may be better served by an LLC's pass-through taxation and flexible governance.
