If the LLC is a disregarded entity for tax purposes, you just claim the rental property income and expenses on your personal return using Schedule E. If the LLC is treated as a partnership, then the partnership's return will provides the information on the property's income/expenses to IRS, and then you each get a schedule K-1 to use for paying the tax on your personal return. If the LLC is treated as a corporation, then it depends whether it is an "S" or "C" corporation and gets taxed as a pass-thru entity or a separate entity, respectively.
