How Do I Choose the Right Business Entity for My Startup?
When starting a new business, the creation of the entity itself is one of the first major decisions you will need to make. How you decide to proceed is extremely important for protecting yourself from legal liability, partner disputes, and tax consequences.
Before we talk about the types of entities, it helps to start with why entities exist at all.
When a person starts a business without creating a legal business entity, their business is referred to as a sole proprietorship. The law draws no distinction between you and the business: its debts are your debts, and a claim against the business can reach your home and personal assets. Forming a legally recognized business entity changes that by limiting your potential liability only to the assets of the company. Forming an LLC, a Corporation, or other business entity creates a separate legal person that can own property, sign contracts, borrow, and sue or be sued in its own name, while shielding the owners’ personal assets if things go wrong. This also allows a company to outlive its founders, take on investors, and divide ownership into shares. Companies are created for the protection of the owners, and the operational flexibility that comes with it.
Typically, there are a few different issues to consider when forming the company:
What type of entity to create;
In what state (and county) to create that entity;
How company decisions will be made;
Who owns how much (if you have more than one shareholder);
How the company and its shareholders will be taxed?
This is an oversimplification, but its a good starting point for thinking about this.
The LLC
A limited liability company gives you liability protection and pass-through taxation with little paperwork. Profits flow to the owners’ personal returns, and you skip the C-corp’s second layer of tax. For consultants, agencies, real estate, and most local businesses, it is the right tool. The limits appear the moment you raise institutional money: venture funds are reluctant to invest in an LLC (it happens but its rare, and usually only as pre-seed rounds), option grants are awkward, and the QSBS tax break, discussed below, is off the table. If a priced round is likely, starting as an LLC just means paying to convert later. For bootstrappers though, LLCs are an attractive option.
The S-corporation: a tax election, not an entity
We often hear prospective clients tell us they want to form an S-Corp. It’s a common misnomer, as an S-Corp is not a type of company, it’s a tax election. An S-corp is a corporation or LLC that elects to be taxed under Subchapter S, combining pass-through treatment with a way to cut self-employment tax. But it can have no more than 100 shareholders, all U.S. individuals or qualifying trusts, and only one class of stock. A venture fund is an entity, and even individual investors typically expect preferred shares, so you can’t elect to be taxed as an S-Corp and also expect VC funding. S-corps fit profitable, closely held businesses, not companies built to raise capital.
The C-corporation, and why Delaware
Most VCs will insist on investing in Delaware C-Corps. A C-corporation is a separate taxpayer: it pays the 21% federal rate, and dividends are taxed again at the shareholder level (this is one reason why LLCs are favored where there is no investment involved). For an early-stage startup that rarely matters, because young companies seldom pay dividends and often operate at a loss. What the C-corp gets you is what investors require: unlimited shareholders, multiple stock classes, a clean option pool, and QSBS eligibility. For venture-track companies the state is almost always Delaware, whose corporate law and Court of Chancery are what investors and term sheets assume. There are reasonable debates about how much it really matters, but the fact is that VCs want Delaware C Corps so they and their attorneys don’t have to operate in several different state legal system. If you are looking for VC investment, 10,000,000 shares are considered standard.
That said, by default Delaware bills a franchise tax on the number of authorized shares method. On 10,000,000 authorized shares it comes to roughly $85,000. To avoid this, recalculate and pay under the assumed par value capital method instead, since the state lets you use whichever method is lower: with a low par value (most startups use $0.0001 per share) and modest gross assets, that method usually drops the tax to a few hundred dollars, often the $400 minimum. Just keep par value very low and don’t authorizing more shares than the company's assets justify.

The QSBS reason to incorporate early
Section 1202 lets shareholders of a qualified small business exclude much of their gain from federal tax on a sale, but only for original-issue stock in a domestic C-corporation. The 2025 federal tax law made it more generous for stock acquired after July 4, 2025: a tiered exclusion of 50% at three years, 75% at four, and 100% at five, a cap of the greater of $15 million or ten times basis, and a $75 million gross-asset ceiling. Confirm the thresholds and your eligibility with a tax adviser, since the rules turn on timing.
Delaware does not get you out of your home state
A Delaware entity does not mean you answer only to Delaware. If you live and work in, say, New York, you are doing business there and must register as a foreign entity and pay local taxes. New York requires new LLCs to publish formation notice in two newspapers for six weeks within 120 days (LLC Law Section 206); miss it and the state can suspend your LLC’s right to sue. California will charge you additional fees if you’re late in registering.
The bottom line
Match the entity to the plan. Funding and scaling points to a Delaware C-corp, and incorporating early starts the QSBS clock. A business you will own and operate points to a home-state LLC, with an S-election if the tax math favors it. The costly mistakes are almost always cleanup later: converting to a C-corp the week before a financing, or finding an unmet New York publication requirement in diligence.
