The most convenient and tax friendly option is certainly LLC in your case. Why? Because, by default, LLCs are taxed through to the members--similar to partnerships--so that you avoid double taxation (ie first taxes on the company's profits and then taxes on your personal income).
Disregarded tax status is a good option for most business owners, especially new owners, as this is a simple taxation option that can automatically be applied to the LLC. In addition, this option does not require any additional paperwork to be taxed as a pass-through entity.
An LLC will file one of the following returns, depending on the situation: Single-member LLCs: Form 1040 (Schedule C, E, or F) Multiple-member LLCs (Partnership): Form 1065. S corporation: Form 1120-S.
