Washington Single-Member LLC (2026)

Solo Doesn’t Mean Unprotected.

You built this business alone. Protect it properly.

Right now, if you get sued for anything business-related — that lawsuit is against you personally. Your bank account, your car, your home equity. All on the table. With a single-member LLC, that lawsuit is against the LLC. Your personal assets stay out of it — as long as you’ve maintained proper separation: separate bank account, operating agreement, clean records. The LLC takes the hit. You keep your savings. What most people don’t know: single-member LLCs still need an operating agreement. Courts have used the absence of one as evidence the LLC wasn’t truly separate from its owner — destroying protection. Corp Nation fixes all of this in one step. For $149 plus the Washington state filing fee: Articles filed correctly, a Washington registered agent, EIN obtained, and a customized single-member operating agreement. You built the business alone. You don’t have to navigate the legal setup alone. Let Corp Nation handle the paperwork.

Frequently Asked Questions

How is a Washington single-member LLC taxed?

As a disregarded entity by default — income goes on Schedule C of your personal return. You can also elect S-Corp status for tax savings once profits exceed ~$40K.

Does a Washington single-member LLC need an operating agreement?

Not legally required in most states, but strongly recommended. It strengthens liability protection and is required by most banks when opening a business account.

What’s the difference between a single-member LLC and a sole proprietorship?

A sole proprietorship offers zero liability protection. A single-member LLC creates a legal wall between your personal assets and business liabilities. That wall is the entire point.
