Every business begins with a decision that most founders make too quickly: what kind of legal entity to form, and how to structure it. That choice — made in the first days of a company’s life — shapes everything that follows. It determines how the business is taxed, how liability flows, who can own shares, whether venture capital is possible, and what happens when owners disagree, exit, or die. Getting it right is not a matter of paperwork. It is one of the most consequential legal decisions a business owner will make.
This section covers the full arc of business formation law in plain language, from choosing the right entity on day one through the complex equity and governance structures that define a venture-backed startup’s cap table. Whether you are a solo founder incorporating for the first time or a seasoned operator restructuring an existing company, the pages here explain what the law requires, what your options are, and what the real-world tradeoffs look like.
Choosing the Right Entity
The most fundamental formation decision is entity type. A Delaware C corporation, the default for venture-backed startups, offers flexible equity structures, favorable tax treatment for qualified small business stock, and the governance framework that institutional investors expect. But it is not always the right answer. An LLC may offer more flexibility and pass-through taxation for businesses that do not need outside investment. An S corporation can work well for closely held businesses that want to avoid double taxation while maintaining corporate formalities. Partnerships, benefit corporations, professional entities, and series LLCs each serve specific purposes that a generic formation approach would miss.
The choice is not permanent, but changing it later is expensive and sometimes impossible without triggering tax. Understanding the differences before you file is far cheaper than restructuring after the fact. This section explains each entity type in detail — its formation requirements, ownership restrictions, tax treatment, governance rules, and the circumstances in which it makes sense.
Formation Documents and the First 90 Days
Filing articles of incorporation or an LLC certificate is only the beginning. The documents that actually govern a company — the certificate of incorporation, bylaws, stockholder agreements, LLC operating agreements, and founder equity grants — are where the meaningful legal work happens. These documents define who controls the company, what protections shareholders have, how decisions get made, and what happens when things go wrong. Founders who skip or rush this step often discover years later that they have no enforceable rights, no protection against dilution, and no clear process for resolving disputes.
The post-formation period is equally important. New businesses must obtain a federal employer identification number, register in every state where they operate, apply for required business licenses and permits, open dedicated business banking accounts, and elect how the entity will be taxed. Missing any of these steps can create compliance gaps, pierce the liability shield the entity was meant to provide, or cost money in penalties that could have been avoided entirely.
Equity, Vesting, and the 83(b) Election
How founders and early employees receive equity — and under what terms — is one of the most important and most misunderstood aspects of company formation. A founder who receives shares subject to vesting but fails to file an 83(b) election with the IRS within thirty days will pay ordinary income tax on the full value of those shares as they vest, often at the worst possible time. A co-founder who does not negotiate for meaningful protective provisions in the stockholder agreement may find herself voted off her own board. An early employee who accepts stock options without understanding the difference between ISOs and NSOs may face a six-figure tax bill when she exercises.
This section covers equity compensation from first principles: how to split founder equity fairly and protect it with vesting, how to size and administer an option pool, when to use ISOs versus NSOs, how profits interests in LLCs compare to stock options in corporations, and how to structure section 1202 qualified small business stock from day one to preserve the potential for a ten-million-dollar federal tax exclusion on exit.
Early-Stage Financing
Most startups raise their first outside capital before they are ready for a priced round of venture financing. The instruments used for that early capital — SAFEs, convertible notes, and the various hybrid structures that have emerged over the past decade — are simple to sign but complex in their long-term consequences. A SAFE that looks founder-friendly can become dilutive in ways the founder did not anticipate when a priced round closes at a down-cap valuation. A convertible note with a high interest rate and a short maturity can create a default right when a startup can least afford it.
When institutional venture capital enters the picture, the equity structure becomes significantly more complex. VC-backed companies issue preferred stock with liquidation preferences, anti-dilution protections, and consent rights that can fundamentally limit what a founder can do. Understanding those terms before signing is not optional — it is the difference between a founder who retains meaningful control and one who has signed away the ability to make major decisions without investor approval.
Governance, Control, and Founder Protection
Corporate governance is not just a concern for public companies. Even a small startup with two founders and one investor needs to think carefully about how the board is composed, who has voting rights on major decisions, what happens if a founder wants to leave or is asked to leave, and whether the company’s charter documents adequately protect the founding team’s ability to run the business they built. Dual-class stock structures, voting agreements, protective provisions, founder-friendly charter amendments, and carefully negotiated employment agreements are all tools that sophisticated founders use to preserve meaningful control even as they take on outside capital.
The Delaware board of directors, with its fiduciary duties of care and loyalty and the business judgment rule that protects most good-faith decisions, operates under a specific legal framework that founders need to understand. The same is true for LLC managers and managing members, who owe duties defined partly by statute and partly by the operating agreement itself.
Tax Planning at Formation
Formation is the optimal moment for tax planning because it is the moment before value has been created. Founders who think carefully about entity classification, the check-the-box regulations, S corporation elections, section 1202 qualification requirements, and carried interest structures at formation can position their companies — and themselves personally — to minimize the tax cost of future growth and exit. The same planning that would be simple and inexpensive at formation can become enormously complex, expensive, or simply unavailable once the company has raised money, hired employees, and started generating revenue.
Delaware franchise tax, often ignored at formation, can produce surprising bills for companies that use the authorized-shares method of calculation. Understanding how to structure the initial capitalization to minimize franchise tax exposure is a practical concern for any Delaware corporation.
