Self-Employed

You're a sole proprietor if you own an unincorporated business by yourself.

If you are the sole member of a domestic limited liability company (LLC), you are not a sole proprietor if you elect to treat the LLC as a corporation. 

You're an independent contractor if the payer has the right to control or direct only the result of the work and not what will be done and how it will be done. The earnings of a person who is working as an independent contractor are subject to Self-Employment Tax.

A partnership is the relationship between two or more people or business entities who join to carry on a trade or business.

Each person contributes money, property, labor, or skill, and expects to share in the profits and losses of the business.

A partnership must file an annual information return to report the income, deductions, gains, losses, etc., from its operations, but does not pay income tax. Instead, it passes through any profits or losses to its partners. Each partner includes his or her share of the partnership's income or loss on their tax return.

You do not have to carry on regular full-time business activities to be self-employed. Having a part-time business in addition to your regular job or business also may be self-employment.
