You own only one business, that is your LLC. If you choose to operate under two different DBAs, that is a matter for state regulation, not the IRS. Because you choose to perform both sets of business activities under the single LLC, you must file a single tax return for the LLC.
Under most circumstances, an LLC with more than one member or owner must file a form 1065 partnership tax return. This creates a K-1 statement for each partner that is entered on the partners personal tax return. However, if you live in a community property state, and if the only two members of the LLC are spouses, then you may file as a qualified joint venture. You will file 2 schedule C ‘s, one in the name of each spouse, and each LLC will list half the business income and half the expenses.
