The application required for incorporating as a Limited Liability Company (LLC) is called the Articles of Incorporation (also referred to as a Certificate of Incorporation). This document contains basic information about the company, its owners, and its directors. Depending on your state of incorporation, there may also be state-level fees or taxes that must be paid.
On the other hand, if you are not responsible for its tax, then you should declare the equipment in Part III of the Business Property Statement (Equipment belonging to others). Where equipment is declared in Part III of the Business Property Statement, the Assessor will also send a Notice to File to the person reported as the equipment's actual owner.
