Before law school, I co-founded companies on two continents, and I made entity decisions the way most founders do: quickly, based on whatever a friend or an internet forum said. Now that I am studying the law behind those choices, I want to write the explainer I needed then.
Why the choice matters at all
Both structures do the one thing sole proprietorships and handshake partnerships do not: they create a legal entity separate from you, so business debts and lawsuits generally stop at the business. That liability shield is the main reason to form anything.
Past that shared feature, the two structures diverge on taxes, formalities, ownership, and who will invest in you. Entity law is state law, so details vary by state, but the broad strokes hold everywhere.
The LLC: flexible by design
A limited liability company is the newer, looser structure. Its owners are called members, and its rulebook is a contract called an operating agreement, which members can write almost however they want.
Taxes. By default, an LLC is a pass-through: the company itself pays no federal income tax, and profits and losses flow to the members’ personal returns. No tax at the entity level, no second tax on distributions.
Formalities. Fewer. Most states do not require annual shareholder meetings, a board of directors, or formal officer roles. That is a real advantage for a two-person business that would otherwise fake its way through corporate rituals.
Flexibility. Members can split profits in ways that do not match ownership percentages, if the operating agreement says so. Corporations generally cannot do that within a single class of stock.
The catch. Flexibility cuts both ways. If your operating agreement is silent or sloppy, you fall back on default state rules that may not match what the founders assumed. Many LLC disputes I have read about trace back to an operating agreement nobody wrote or nobody read.
The corporation: rigid, and sometimes that is the point
A corporation has shareholders who own it, a board of directors who govern it, and officers who run it, even if all three are the same person at the start. The formalities are mandatory: bylaws, board approvals, stock issuance, annual meetings, minutes.
Taxes. A standard C corporation pays corporate income tax, and shareholders pay tax again on dividends. That is the famous double taxation. Smaller corporations that qualify can elect S corporation status with the IRS, which restores pass-through treatment but caps the company at 100 shareholders, one class of stock, and generally US-individual owners.
Stock. Corporations can issue different classes of shares, grant stock options, and put equity into the standardized packages that employees and investors expect.
Investors. This is the deciding factor for many startups. Venture capital funds overwhelmingly prefer, and often require, a corporation, typically a Delaware C corporation. Their fund structures, preferred-stock terms, and option pools are all built for corporate stock, not LLC membership interests. If your realistic plan is to raise institutional money, that plan is effectively choosing your entity for you.
A rough sorting rule
- Small business, professional practice, real estate holding, or a company you plan to fund from revenue: the LLC’s simplicity and single layer of tax usually win.
- Startup planning to raise venture capital, grant employee stock options, or eventually sell or go public: corporation, and probably a Delaware C corporation.
- Mission-driven venture: you may be choosing between a nonprofit and a for-profit entity before you ever reach LLC vs corporation. That is a different fork; see the public charity explainer.
And remember conversion exists. Companies convert from LLC to corporation regularly, often right before a first institutional financing. Starting as an LLC is rarely fatal; it is just paperwork and tax analysis later.
The mistakes that actually hurt founders
The entity choice gets the attention, but in my experience the damage comes from what happens after formation:
- No written operating agreement or bylaws. The state’s default rules become your deal, and nobody knows what they say.
- Commingling money. Paying personal expenses from the business account is the classic way courts justify “piercing the veil” and holding owners personally liable, which defeats the entire point of forming an entity.
- Handshake equity. Founders who never document who owns what, or what happens when someone leaves, are setting up the dispute that ends the company.
- Ignoring the formalities you signed up for. If you chose a corporation, hold the meetings and keep the minutes. Courts notice when a corporation exists only on paper.
The honest bottom line
For a genuinely simple business, either structure protects you if you respect it. The choice becomes consequential when investors, employees with equity, multiple owners, or multi-state operations enter the picture, and that is exactly when a few hundred dollars of a business lawyer’s time, plus a conversation with an accountant about the tax side, is the cheapest insurance you will ever buy.
