Delaware S-Corp vs C-Corp: Which Structure Fits Your Stage
Maya Rodriguez
Founder & CEO
The S-corp vs C-corp question depends entirely on your growth plan and funding strategy. Here is how to think through the decision for a Delaware company.
Core Tax Differences
A C-corporation is taxed at the entity level at the federal rate of 21%. When profits are distributed as dividends, shareholders pay tax again at their individual rate, creating double taxation. An S-corporation is a pass-through entity. The corporation itself pays no federal income tax. Instead, income and losses flow through to shareholders' personal returns and are taxed once at individual rates. For a profitable company with no plans to raise VC funding, the S-corp structure can save significant tax. For a pre-revenue startup burning cash, the pass-through losses can offset other income on the founders' personal returns, subject to basis, at-risk, and passive activity limitations.
Why VCs Require C-Corps
S-corporations cannot have more than 100 shareholders, cannot have non-US shareholders, cannot have entity shareholders (which excludes most VC fund structures), and can only issue one class of stock. Venture deals require preferred stock with liquidation preferences, anti-dilution provisions, and other structural features that demand multiple stock classes. An S-corp cannot accommodate any of this. If you plan to raise institutional venture capital, you must be a C-corp. There is no negotiation on this point. The practical implication is that the S-corp election makes sense for bootstrapped companies, professional service firms, and companies funded by individual angels who are comfortable with pass-through taxation.
The Conversion Path
If you start as an S-corp and later need to become a C-corp, the conversion is straightforward. You revoke the S election by filing a statement with the IRS signed by shareholders holding more than 50% of the stock. The revocation can be effective on a specified future date. There is no tax at the entity level on the conversion itself, though any built-in gain on assets may be subject to the built-in gains tax under Section 1374 if the company later reverts to S-corp status. Converting from C-corp to S-corp is more complex, with a five-year built-in gains recognition period and restrictions on accumulated earnings and profits. If you think there is even a modest chance of raising VC, start as a C-corp.
Practical Recommendation by Stage
For venture-track startups at any stage, use a C-corp. The QSBS exclusion under Section 1202 can eliminate up to $10 million in capital gains tax, which more than compensates for double taxation in most exit scenarios. For bootstrapped SaaS companies with one to three founders and no plans to raise institutional capital, the S-corp can save 10% to 15% on self-employment taxes by allowing you to split income between a reasonable salary and distributions. For consulting firms, agencies, and professional services, the S-corp is often the right choice for the same self-employment tax reasons. At SpryTax, about 70% of our clients are C-corps because they are on the venture track, but we structure S-corps regularly for profitable bootstrapped businesses.
