Your question is not clear about whether you and your husband each have your own separate LLC, or if you and your husband are both members of the same LLC. But in all cases it will almost certainly be better to file jointly, as xmasbaby0 said.
If you have two separate LLCs, and each LLC has only one member, the LLCs are disregarded for income tax purposes. You file your tax return as if the LLCs did not exist. You have two separate businesses. You report each business on Schedule C in your joint personal tax return.
If you and your husband are both members of the same LLC, then it's a multi-member LLC. If you do not live in a community property state, the multi-member LLC has to be treated as a partnership. The LLC has to file a partnership tax return, Form 1065. The partnership return includes a Schedule K-1 for each member. You each have to enter information from your Schedule K-1 in your joint personal tax return.
If you do live in a community property state, you have a choice as to how you treat the LLC on your tax return. You can choose to treat the LLC as a partnership, as described above. The other choice, if you and your husband are the only members of the LLC, is to treat the LLC as a "disregarded entity." You would file your joint tax return as if the LLC didn't exist. You and your husband would each file a Schedule C for your respective shares of the business income and expenses.
The community property states are Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin.
Again, in all cases it will almost certainly be better to file jointly.
