Which business structure is right for you?

Choosing how to structure your business is one of the first decisions you'll make — and one of the ones that matters most. It affects your taxes, your liability, how you pay yourself, and how complicated your bookkeeping gets. Get it right early, and a lot of other things fall into place. Get it wrong, and you're either leaving money on the table or dealing with a restructuring conversation later.

Here's a plain-language breakdown of the most common business structures, what they're good for, and where they fall short. If you want something you can save and reference later, I put together a one-page handout that covers all of this in a single view — grab it from the Prism resource library.

Sole proprietorship

The simplest structure there is. You're the business. No separate entity, no formal setup, no separate tax return. You report your income and expenses on Schedule C and pay self-employment tax on your net profit.

The upside: Low friction. Easy to start, easy to run, easy to close. If you're testing an idea, doing seasonal work, or running a home-based business with limited liability exposure, this gets you moving without bureaucracy.

The downside: No liability protection. If someone sues the business, they're suing you personally. You're also paying self-employment tax on every dollar of net profit, and access to fringe benefits as the owner is limited.

Good fit for: Part-time or seasonal businesses, home-based operations, and businesses where the owner doesn't expect to outlive the work.

Single-member LLC

Functionally similar to a sole proprietorship for tax purposes — same Schedule C, same self-employment tax on net profit — but with one important difference: liability protection. The LLC is a separate legal entity, which means your personal assets have a wall between them and the business (with the usual exceptions for your own malpractice or personally guaranteed debt).

The upside: The simplicity of a sole proprietorship with a meaningful layer of protection. Still no separate tax return. Still easy to run.

The downside: You're still paying self-employment tax on the full net profit. LLC rules vary by state, and failure to follow the formalities can cost you your liability protection. Fringe benefit access for owners is still limited.

Good fit for: Businesses with real liability exposure where the owner plans to operate indefinitely.

Multi-member LLC

Two or more owners, taxed as a partnership by default. Each member's share of profits and losses flows through to their personal return. No entity-level income tax.

The upside: Flexible ownership structure, no double taxation, and the ability to transfer membership interests more easily than in a single-member setup. Unlimited number of members. Good for businesses that need equity partners or plan to grow beyond the founding owner.

The downside: Requires a separate tax return (Form 1065). State LLC laws vary, and you need to actually follow the formalities to keep your liability protection intact.

Good fit for: Businesses that need outside capital, have operational liability, or expect ownership to change over time.

General partnership

Two or more owners, no formal incorporation. Profits and losses pass through to partners. No double taxation.

The upside: Flexible profit and loss allocations, no restrictions on partner type or number, favorable tax treatment on liquidation.

The downside: Every general partner has unlimited personal liability for the business's debts and lawsuits. Dissolving or transferring ownership is complicated. Each partner's share of income is subject to self-employment tax.

Good fit for: Two established businesses that want to work together, or partners consolidating multiple entities under one umbrella.

Limited liability partnership (LLP)

A partnership structure where limited partners have liability protection up to their investment. At least one general partner still carries unlimited liability.

The upside: Limited partners aren't on the hook beyond what they've put in. Flexible for businesses with investors who aren't actively running operations.

The downside: Someone always has to be the general partner with full exposure. LLC status can be lost if you don't follow the administrative requirements. Requires a separate return and careful tracking of partner basis.

Good fit for: Businesses with passive investors, significant liability exposure, or equity capital needs.

S corporation

An S corp is a corporation that's elected to be taxed as a pass-through entity. Profits flow to shareholders without being taxed at the entity level. Shareholders who work in the business are paid as W-2 employees.

The upside: The self-employment tax treatment is the big one. As an S corp owner-employee, you pay yourself a reasonable salary (subject to payroll taxes), and distributions above that salary aren't subject to self-employment tax. That can add up to real savings. Losses flow through to offset other income. Liability is limited to your investment.

The downside: Complex and more expensive to set up and maintain. Requires a separate tax return, board meetings, and minutes. Ownership is restricted — only certain entities can be shareholders, and there's a 100-shareholder cap. Fringe benefit deductibility for owner-employees is limited.

Good fit for: Businesses with significant liability exposure and profitable enough to justify the administrative overhead.

C corporation

A full legal entity, taxed separately from its owners. Shareholders pay tax on dividends, meaning profits can be taxed twice — once at the corporate level (21%) and again when distributed.

The upside: No liability for non-active shareholders. Unlimited shareholders, no restrictions on entity type. Perpetual existence. Fringe benefits for owner-employees are broadly available. Raising capital can be as straightforward as issuing stock. Losses stay in the corporation.

The downside: Double taxation on profits distributed as dividends. Complex and expensive to run. Requires formal governance (board meetings, minutes, annual filings). Losses don't flow through to shareholders.

Good fit for: Businesses planning to hold ownership in other entities, those with significant liability exposure, or businesses built to exist indefinitely — especially if they plan to raise outside investment.

A note on business formalities

Whatever structure you choose, follow the rules that come with it. The liability protection of an LLC or corporation isn't automatic — it can be lost if you're mixing personal and business funds, failing to capitalize the business properly, or not maintaining the required records. Courts can pierce the corporate veil if the business looks like an extension of you personally. Keeping clean books and a separate business account isn't just good practice. It's what makes your protection real.
