Are you self-employed? You are self-employed if you carry on a trade or business as a sole proprietor or an independent contractor.

Sole proprietor. A sole proprietor is someone who owns an unincorporated business by himself or herself. However, 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.

Trade or business. A trade or business is generally an activity carried on to make a profit. The facts and circumstances of each case determine whether or not an activity is a trade or business. You do not need to actually make a profit to be in a trade or business as long as you have a profit motive. You do need to make ongoing efforts to further the interests of your business.

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 may be self-employment.

Independent contractor. People such as doctors, dentists, veterinarians, lawyers, accountants, contractors, subcontractors, public stenographers, or auctioneers who are in an independent trade, business, or profession in which they offer their services to the general public are generally independent contractors. However, whether they are independent contractors or employees depends on the facts in each case. The general rule is that an individual is an independent contractor if the payer has the right to control or to direct only the result of the work and not how it will be done. The earnings of a person who is working as an independent contractor are subject to self-employment tax. For more information on determining whether you are an employee or independent contractor, see Publication 15-A, Employer's Supplemental Tax Guide.

Statutory employee. A statutory employee has a checkmark in box 13 of his or her Form W-2, Wage and Tax Statement. Statutory employees use Schedule C or C-EZ to report their wages and expenses.

Limited liability company (LLC). A limited liability company (LLC) is an entity formed under state law by filing articles of organization. Generally, a single-member LLC is disregarded as an entity separate from its owner and reports its income and deductions on its owner's federal income tax return. An owner who is an individual may use Schedule C or C-EZ.

Husband and wife business. If you and your spouse jointly own and operate an unincorporated business and share in the profits and losses, you are partners in a partnership, whether or not you have a formal partnership agreement. Do not use Schedule C or C-EZ. Instead, file Form 1065, U.S. Return of Partnership Income. For more information, see Publication 541, Partnerships.

Exception—Community income. If you and your spouse wholly own an unincorporated business as community property under the community property laws of a state, foreign country, or U.S. possession, you can treat the business either as a sole proprietorship or a partnership. The only states with community property laws are Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin. A change in your reporting position will be treated as a conversion of the entity.

Exception—Qualified joint venture. If you and your spouse materially participate as the only members of a jointly owned and operated business, and you file a joint return for the tax year, you can make a joint election to be taxed as a qualified joint venture instead of a partnership. To make this election, you must divide all items of income, gain, loss, deduction, and credit between you and your spouse in accordance with your respective interests in the venture. Each of you must file a separate Schedule C or C-EZ.
