Startup Formation & Entity Structure

Choosing a startup entity is a financing and ownership decision as well as a filing task. A company developing a prototype for outside investment may need a different structure from a closely held service business. Philip Falco, Attorney & CPA, helps founders evaluate the legal documents and tax consequences together.

Start With the Owners and the Funding Plan

Identify who will contribute cash, intellectual property, and services; where the owners live; whether institutional investors are expected; and how employees will participate in ownership. Review expected losses, future distributions, and a potential sale alongside the cost of maintaining the entity.

A corporation may fit a plan involving preferred shares and successive investment rounds. An LLC may fit a business seeking flexible economic arrangements, but partnership taxation and later conversion can add complexity. Neither choice should be made solely from the first year’s tax estimate.

Legal Structure and Tax Classification Are Different

A domestic single-member LLC generally defaults to disregarded treatment for federal income tax, while a domestic multi-member LLC generally defaults to partnership taxation unless it elects corporate treatment. An EIN does not replace formation documents or establish every tax election. See the IRS LLC classification guidance.

S corporation status has ownership and capital-structure limits, including restrictions on eligible shareholders and a one-class-of-stock requirement. These rules can conflict with a proposed investor group or preferred economics. Review the IRS S corporation requirements before electing that treatment.

Complete the Ownership Records, Not Just the State Filing

• Prepare governing documents and initial organizational approvals.
• Document founder contributions, stock purchases or membership interests, and payment.
• Agree on vesting, departure terms, voting, and transfer restrictions.
• Transfer relevant founder-created IP and review existing obligations.
• Establish banking, accounting records, tax accounts, and a filing calendar.
• Reconcile the ownership ledger with executed documents and approved grants.

Formation in another state can create additional registration, reporting, and fee obligations where the company actually operates. Compare the full cost and governance needs before selecting a jurisdiction. Foreign founders or foreign operations also warrant international tax review.

Coordinate the First Equity Issuance

Do not treat a promise of shares as interchangeable with an approved and completed issuance. Establish the transfer date, price, valuation support, and restrictions. Restricted founder stock can create a short §83(b) election window. An employee option program requires a separate valuation and equity-compensation review.

When the Company Already Exists

Bring the actual formation documents, elections, ownership records, and returns. Review missing approvals, undocumented founder loans, personally owned IP, and inconsistent ownership percentages before accepting new money. Changing the structure may require consents and tax analysis; it is not simply a new EIN application.

What to Bring to a Formation Consultation

Provide the founder list, proposed ownership split, locations, existing agreements, development budget, expected financing instruments, and any equity already promised. Explain whether the business is intended to distribute profits or reinvest toward growth and a future exit.
