Can a husband and wife run a business as a sole proprietor or do they need to be a partnership?

It is possible for either the husband or the wife to be the owner of the sole proprietor business. When only one spouse is the owner, the other spouse can work in the business as an employee. If the spouses intend to carry on the business together and share in the profits and losses, then they have formed a partnership. See Rev. Proc. 2002-69 for Special Rules for Spouses in Community States.

For IRS purposes, how do I classify a limited liability company? Is it a sole proprietorship, partnership or a corporation?

A limited liability company (LLC) is an entity formed under state law by filing articles of organization as an LLC. Unlike a partnership, none of the members of an LLC are personally liable for its debts. An LLC may be classified for Federal income tax purposes as if it were a sole proprietorship (referred to as an entity to be disregarded as separate from its owner), a partnership or a corporation. If the LLC has only one owner, it will automatically be treated as if it were a sole proprietorship (referred to as an entity to be disregarded as separate from its owner), unless an election is made to be treated as a corporation. If the LLC has two or more owners, it will automatically be considered to be a partnership unless an election is made to be treated as a corporation. If the LLC does not elect its classification, a default classification of partnership (multi-member LLC) or disregarded entity (taxed as if it were a sole proprietorship) will apply. The election referred to is made using the Form 8832 (PDF), Entity Classification Election. If a taxpayer does not file Form 8832 (PDF) , a default classification will apply.

Does a small company need a tax ID number?
