Start your own corporation

Entity structure, limited liability, and separating business risk from personal assets

Garrett Sutton's Start your own corporation is a practical argument for separating business risk from personal assets through legal entity structure.

The central idea is simple: the form through which a business operates changes who bears liabilities, how ownership is organized, how decisions are documented, and how profits may be taxed. Entity choice is therefore not administrative trivia. It is part of risk design.

“Own nothing and control everything.”
— Garrett Sutton, Start your own corporation

Core framework

  • Sole proprietorship — one person and the business are legally inseparable for liability purposes
  • General partnership — partners can expose one another to business liabilities
  • Corporation — a separate legal entity owned by shareholders
  • Limited liability — owners generally risk their investment rather than all personal assets
  • S corporation — a corporation that can elect qualifying pass-through tax treatment
  • LLC — a flexible entity combining limited liability with configurable management and tax treatment
  • Corporate formalities — records, accounts, filings, governance, and separation required to preserve the entity's distinct status
  • Personal guarantee — a contractual decision that can restore personal liability for a particular obligation

The point of an entity is not paperwork. It is to create a legal boundary between the operating risk of the business and the personal balance sheet of the owner.

Separate the person from the business

A sole proprietorship creates no meaningful liability boundary.

“Sole proprietorships and general partnerships provide no asset protection.”
— Garrett Sutton

If the business incurs an obligation or loses a lawsuit, the owner may face personal exposure.

A corporation or LLC creates a separate legal entity.

“A good entity is one that shields and protects your personal assets from business risk.”
— Garrett Sutton

That separation is the core mechanism.

Partnerships multiply agency risk

A general partnership adds another problem: each partner can create obligations for the partnership.

The risk is therefore not only your own judgment.
It is the judgment of people legally empowered to act for the enterprise.

This makes governance important before the business becomes large.

Key idea: Shared ownership without explicit authority, economics, and exit rules converts trust into unpriced legal risk.

Limited liability is conditional

Forming an entity is not enough.

Owners must treat the business as genuinely separate through distinct accounts, records, contracts, filings, and governance.

Sutton emphasizes corporate formalities because courts can sometimes disregard the entity when owners treat it as indistinguishable from themselves.

Personal guarantees create another exception.

A lender, landlord, or other counterparty may require the owner to promise repayment personally even when the company itself is the borrower.

Limited liability is a structure to preserve, not a permanent immunity created by filing one document.

Entity choice follows function

Sutton compares corporations, S corporations, LLCs, and partnerships because no structure is universally optimal.

The right choice depends on variables such as:

  • number and type of owners
  • capital needs
  • desired governance
  • tax treatment
  • expected distributions
  • future investors
  • plans to sell or go public
  • state law

The durable lesson is not which entity to choose. It is that legal structure should follow the economic structure of the business.

Implications

The book's useful contribution is upstream thinking about business formation.

Many founders focus first on product, customers, and revenue. Sutton adds another layer: who owns the risk, what entity signs the contract, what happens if the business fails, and which assets remain exposed.

The key qualification is that entity law and tax rules vary by jurisdiction and change over time. The book is a framework for understanding the design problem, not a substitute for current legal or tax advice.

The practical questions are:

  • Which liabilities can this business create?
  • Which entity will incur them?
  • Which personal assets remain exposed?
  • Am I signing personal guarantees?
  • Are business and personal finances actually separate?
  • Does the ownership structure match future capital needs?
  • Are governance and exit rights explicit?

The enduring idea is straightforward: business formation is partly an exercise in deciding where failure is allowed to stop.
