Can I change my structure later?

Yes. Many owners start as an LLC and elect S corp taxation once profits grow, without forming a new company. Converting to a C corporation later is also possible, though it takes more paperwork.

Why not just operate under my own name?

Without an entity, you are personally on the hook for business debts and lawsuits. An LLC is inexpensive to form, separates business from personal assets and makes banking and bookkeeping cleaner, which is why we recommend it as the starting point.

Do I need an operating agreement?

Washington doesn't require you to file one, but every LLC should have one. It sets out ownership, decision-making and what happens if an owner leaves, and banks often ask for it. We prepare it as part of formation.

Can a multi-member LLC be an S corp?

Yes, as long as every owner is an eligible shareholder (generally US citizens or residents), there are no more than 100 owners and profits are split by ownership percentage.
