LLC vs. Sole Proprietorship: Which Is Right for Your New Business?

"Should I form an LLC?" is one of the first questions almost every new business owner asks. The honest answer is: it depends on your risk, your plans and how much paperwork you're willing to handle. Here's how the two most common structures compare.

What is a sole proprietorship?

A sole proprietorship is the default. If you start doing business on your own and don't form an entity, you're a sole proprietor. There's no state formation filing, though you still need a business license and the right tax registrations.

Pros: simple, inexpensive, minimal ongoing paperwork. Cons: you and the business are legally the same. If the business is sued or can't pay a debt, your personal assets can be at risk.

What is an LLC?

A limited liability company is a separate legal entity you create by filing with the Secretary of State. It's popular because it combines liability protection with flexible taxes.

Pros: helps separate business liabilities from personal assets, looks more established to clients and banks, and gives you tax options later (such as an S-corp election). Cons: formation fee, an annual report every year, and more discipline required to keep business and personal money separate.

How are they taxed?

This surprises many people: by default, a single-member LLC is taxed exactly like a sole proprietorship. The IRS treats it as a "disregarded entity." You report profit on Schedule C of your personal return and pay self-employment tax on it.

A multi-member LLC is taxed as a partnership by default and files its own informational return. Either kind of LLC can later elect to be taxed as an S corporation, which can reduce self-employment tax once profits are high enough.

In Washington, both structures pay the state B&O tax based on gross receipts, and both collect sales tax if they sell taxable goods or services.

When a sole proprietorship makes sense

• You're testing an idea with low risk and low revenue
• You work alone, without employees, and have little liability exposure
• You want the absolute minimum of paperwork while you get started

When an LLC makes sense

• You work in clients' homes, handle physical goods, or give professional advice
• You have (or plan to have) employees or partners
• You want a professional image and a clean separation of finances
• You expect profits high enough that an S-corp election may pay off

A common mistake

An LLC only protects you if you treat it as a separate business. Paying personal bills from the business account or never signing contracts in the LLC's name can weaken that protection. Separate accounts and clean books are part of what makes the LLC work.

The bottom line

For many service businesses, contractors and anyone who works with the public, an LLC is worth the modest cost. For a low-risk side project, a sole proprietorship can be a fine starting point, and you can convert later. Talk through your specific risks with a professional before deciding.
