Mr. LLC has many personalities depending on the number of owners, management, and taxation.
If you plan on having one owner in your business, then you’re a single-member LLC. If you plan on having more than one owner, then you’re a multi-member LLC.
If you plan on having all the owners involved in the day-to-day management of your business, then you’re a member-managed LLC. If not, then you need to select your manager and your LLC will be manager-managed.
If you plan on having assets or employees that make you money, then you’ll want to work with your CPA and probably elect to be taxed as an S Corporation to save on social security and medicare taxes. In some cases you may still elect to be taxed as a partnership, but you can arrange things to minimize these taxes. Otherwise you’ll want to be taxed as a disregarded entity if you’re a single member LLC or as a partnership if you’re a multi-member LLC.
Once you’ve answered these questions, you’ll want to draft an operating agreement.
