You can get these forms from the IRS on their website at www.irs.gov. Send the tax return and schedules, along with your self-employment tax, to the IRS. Even if you don’t owe any income tax, you must complete Form 1040 and Schedule SE to pay self-employment Social Security tax. This is true even if you already get Social Security benefits. Family business arrangements Family members may operate a business together. For example, a husband and a wife may be partners or run a joint venture. If you operate a business together as partners, you should each report your share of the business profits as net earnings on separate self-employment returns (Schedule SE). This is the case even if you file a joint income tax return. The partners must decide the amount of net earnings each should report (for example 50% and 50%). Also, a husband and wife who both materially participate in a jointly owned business, and file a joint return, can make an election to be taxed as a qualified joint venture instead of a partnership. Each must file a separate Schedule C or C-EZ.
