Most founders choose a business structure on an afternoon, while filling a formation website, based on what a friend did. It seems a formality, but the choice will determine how your profits are taxed, what potential investors will accept, and how much bureaucracy you'll have to deal with every year. And it's much more expensive to change a structure later than to get it right at launch.
An LLC and a Corporation both offer limited liability, meaning that the debts and liabilities of the business are kept separate from the personal assets of the owner. They differ in taxation, management structure and ease of compliance, and the desirability of its shares for outside investment.
For most small private companies planning on retaining earnings, an LLC is much simpler to setup and manage. For a large firm planning to raise venture capital, a C Corporation (usually formed in Delaware) is the standard the industry expects.
The regret I see most often runs in both directions. One version is a consulting firm or a small eCommerce brand that incorporated in Delaware because it's what startups do, and is now paying corporate tax, franchise tax, and a registered agent in two states for a business that was never going to raise a dollar. Before you pick a structure, decide whether you'll ever take outside equity.
Anu Gupta, CA, EA, B.Tech · LinkedInLLC vs Corporation: Core Comparison
An LLC (Limited Liability Company) and a corporation are both formal business structures that provide limited liability protection, your personal assets are generally shielded from business debts and lawsuits. The key differences are in taxation, management structure, regulatory burden, and ability to raise capital.
| Dimension | LLC | Corporation (C-Corp) |
|---|---|---|
| Legal Status | Separate legal entity; owners called 'members' | Separate legal entity; owners called 'shareholders' |
| Formation | Articles of Organization + state filing fee | Articles of Incorporation + state filing fee; more formalities |
| Taxation | Pass-through by default (income taxed on members' returns) | Double taxation: corporate tax + shareholder dividend tax (unless S-Corp elected) |
| Management | Flexible, member-managed or manager-managed | Formal, Board of Directors + Officers; annual meetings required |
| Profit Distribution | Flexible, members can agree on any allocation | Dividends, must be proportional to share ownership |
| Equity/Fundraising | Cannot issue stock; harder to bring in investors formally | Can issue multiple classes of stock; preferred by VCs and investors |
| Ongoing Compliance | Minimal, operating agreement, annual state report | Significant, bylaws, board minutes, annual meetings, officer appointments |
| IPO Potential | LLCs cannot go public directly, must convert to C-Corp | Can go public via IPO |
| Best For | Small businesses, single-owner businesses, service firms | Venture-backed startups, businesses seeking institutional investment or IPO |
Types of LLC
| LLC Type | Key Feature |
|---|---|
| Single-Member LLC | One owner, taxed as sole proprietorship by default (Schedule C) |
| Multi-Member LLC | Two or more members, taxed as partnership by default (Form 1065) |
| Series LLC | Multiple 'cells' under one umbrella, each cell protected from other cells' liabilities. Available in limited states. |
| Professional LLC (PLLC) | For licensed professionals (doctors, lawyers, accountants, architects), provides liability protection within the professional services context |
Types of Corporation
| Corp Type | Key Feature |
|---|---|
| C Corporation | Standard corporation, unlimited shareholders, multiple stock classes, subject to corporate income tax (21%). Required for VC investment and IPOs. |
| S Corporation | Pass-through taxation, avoids double taxation. Max 100 shareholders, US citizens/residents only, one class of stock. Popular for profitable small businesses to reduce self-employment tax. |
| Nonprofit Corporation | Tax-exempt, no profit distributed to owners. Can receive tax-deductible donations. Requires 501(c)(3) IRS approval for charitable status. |
| Professional Corporation (PC) | For licensed professionals, similar to C-Corp with additional restrictions depending on state |
How Each One Is Taxed -LLC vs Corporation
LLC (default). Profits pass through to the members' personal returns and are taxed at individual rates, with no tax at the entity level. Members who work in the business also pay self-employment tax on their share. Many pass-through owners can take the qualified business income (QBI) deduction on part of that income.
LLC or corporation with an S-Corp election. Owners who work in the business pay themselves a reasonable salary through payroll, and the remaining profit comes out as distributions that aren't subject to self-employment tax. The savings are real, but so are the costs of running payroll, filing an 1120-S, and defending the salary figure. The election usually starts to make sense once profit reaches the low six figures.
C Corporation. The company pays 21% federal tax on its profits. Profits paid out as dividends are taxed again on the shareholder's return, at up to 20% plus the 3.8% net investment income tax. At the top rates, the combined federal tax on distributed profits comes close to 40% before state tax. Founders accept this because venture-backed companies reinvest instead of paying dividends, and because C-Corp stock may qualify for the qualified small business stock (QSBS) exclusion on a future sale.
Choosing Based on Where the Business Is Going
For most businesses the decision comes down to one question: will you ever sell equity to outside investors? If the honest answer is no, the C-Corp's advantages mostly go unused while its tax and compliance costs don't. An LLC keeps things simpler, and if profits grow, an S-Corp election captures much of the tax benefit people associate with incorporating.
If you do plan to raise institutional money, the calculation flips. Forming as a C-Corp from the start avoids a conversion under deadline pressure, keeps the cap table in a form investors already understand, and starts the QSBS holding period sooner.
We had been operating as an LLC for several years, but as our profits grew, we wanted to understand whether an S-Corp election made sense for us. Profitjets reviewed our income, owner compensation, and tax position and helped us make the change. After the election, we had a clearer structure for payroll and owner compensation and a better understanding of our ongoing tax obligations.
Profitjets advised on approximately 85 S-Corp elections over the past year, with LLCs representing roughly 70% of the businesses it serves.

FAQs
Should a startup choose an LLC or a C-Corp?
If you plan to raise venture capital, form a Delaware C-Corp. Investors expect preferred stock, founder vesting, and a cap table they can read, and most VC funds can't hold LLC interests without creating tax problems for their own investors. If you don't plan to raise institutional money, an LLC is usually the better starting point. Form it in the state where you actually operate. Forming elsewhere typically means registering in your home state anyway and paying two sets of fees.
Is an S Corporation an LLC or a corporation?
Neither. It's a tax status. A corporation can elect it, and so can an LLC, which keeps its legal structure and changes only how the IRS taxes it. To qualify, the business can have no more than 100 shareholders and one class of stock, and generally no corporate, partnership, or nonresident alien shareholders.
Can you convert an LLC to a corporation later?
Yes. Many states allow a direct statutory conversion, and there are other methods, such as contributing the LLC's assets or membership interests to a new corporation. Done properly, a conversion is often tax-free. It can still trigger tax in some situations, for example when the LLC's liabilities exceed the tax basis of its assets. Work through the method with a CPA and an attorney before filing anything, because the method you pick decides the tax result.
Does an LLC protect me from everything?
No. Limited liability covers business debts and claims against the business, but courts can set it aside if you mix personal and business money, skip basic record-keeping, or leave the company undercapitalised. It also won't help with anything you personally guarantee, which includes most small business loans and many leases. A separate bank account and clean books do more to preserve that protection than most owners realise.
Which is cheaper to run each year?
Usually the LLC. A single-member LLC often files no separate federal return, and state costs are typically a modest annual report fee or flat tax. A C-Corp needs its own federal return, board and shareholder records, and franchise tax. In Delaware, that tax can be much higher than necessary if it's calculated under the default method, so check which method your bill uses.
