Frequently Asked Questions

How is a Montana 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 Montana 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.
